Protecting Your Privacy on GEDmatch

Recently, I posted my misgivings about law enforcement agencies using GEDmatch to solve cold cases. In that post, I said I would follow up on privacy options for GEDmatch users. I'll also be demonstrating how to delete various kinds of data from the site, for those who feel they are best served by that option.




Public, Private, and Research Settings


Up until this point, my main method of finding and interacting with cousin matches has been the One-to-Many match list. This would also be the primary means that law enforcement agents and their representatives would use to find me on GEDmatch. So the best way to keep them from being able to do that would be to change the privacy options of my match data.

  • Public - allows anyone on GEDmatch to see you kit number in their match list, and to run comparison utilities across the site to establish relationships. Is the best option if you don't care who accesses your data on GEDmatch and how they use it.
  • Private - removes your kit number from the match list. Doesn't allow for anyone to use your kit number in the comparison utilities on GEDmatch, even if they know it. Is the best option if you want to establish a completely invisible presence on GEDmatch to see your match list, but have no intentions to communicate with anyone there or to use their analysis utilities.
  • Research - removes your kit number from the match list, but allows those who already have your kit number to use other GEDmatch utilities to analyze your data. Is the best option if you want to control who has access to your kit numbers and how they use them.
I weighed each of these options and chose the one that most closely reflects how I want my data to be used, and what I want my relationship with GEDmatch users to look like going forward.


My New Approach to Using GEDmatch


I want to continue having access to GEDmatch and the tools and data it offers. I'm not interested in removing my data or locking myself out of the comparison utilities that GEDmatch offers. The Research option, therefore, is the best one that fits my needs for now. As long as my data is present and available in any form on GEDmatch, I know I can't ultimately stop someone who tries hard enough from getting access to my data. But I can make it sufficiently inconvenient for the wrong people who don't want to go that far out of their way. My hope is that this will be an effective deterrent to people I don't want to have access to my data.

Instead, I'm choosing to make my kit number available in places where family and other genealogists are most likely to see it. By making it available on my profiles with testing companies, social media, and in the Facebook groups for the surnames and locations where I research, I'm still allowing others to use GEDmatch with me. Rather than relying on the One-to-Many match list as the source of those connections, I can create those opportunities where they're most likely to produce real results.

Rather than passively waiting for connections to happen, this approach puts the onus on me to go and make those connections myself. In conjunction with all the other tools available to me, this seems like the best option for me going forward with GEDmatch. And if that ever changes, I won't hesitate to make more adjustments.

Questioning the Ethics of Law Enforcement Using GEDmatch to Solve Cold Cases

No one has been a stronger, more willing advocate of GEDmatch.com than I have been over these past several years. I believe in the ideals of sharing and cooperation that brought that website into existence. It seemed like a win-win for all. Buy one DNA test, then share your results with other genealogists who tested at other companies? It's like buying all the DNA tests for the price of one!

And let's not forget that GEDmatch exists to fill a market gap, which AncestryDNA created purposefully by refusing to provide full segment data to its users. In many respects, I wouldn't need GEDmatch if AncestryDNA would provide the same amount of information between its users that every other testing company does. It's the single biggest dependence on GEDmatch that I currently experience as a user of that site.

Because of how much I've encouraged people to use GEDmatch in the past, I would be remiss if I didn't dive into the changing landscape of DNA testing and GEDmatch's place in it. I never thought I would have to say this, but it's time for every person who uses GEDmatch to reconsider their presence on that website because of the problematic, invisible relationship it currently has with law enforcement.

You may have seen cases in the news related to the Golden State Killer, and the role that GEDmatch played in the solving of that case. I was alarmed the moment I heard that story. I have been watching for how the situation would play out, to see if that case would somehow exist in isolation. I wasn't ready to consider losing one of the most important tools I use for genetic genealogy. I had naive hopes that the situation wouldn't progress beyond that point, and everything could go back to the way it was before.

Except it hasn't. And I see now that it won't. Several more cases have been solved by using crime scene DNA, in comparison with DNA submitted by hobbyist genealogists from all over the world to GEDmatch. And I personally don't understand why more people aren't deeply troubled by this situation. There are so many legal, moral, and ethical issues in that one sentence alone. I'm no legal expert, so I can't pretend I have all/the best/the right answers.

But I'm a concerned person with questions, a conscience, and Constitutional rights. So that's what I want to explore today.

Transparency


The first issue I see in this situation is one of transparency--both on the part of the law enforcement community and the genealogists who represent them. Just roaming around on GEDmatch (like you do), you can't tell who could be a law enforcement agent and who isn't. You can't tell who their representatives are. There's no system in place that allows them to identify themselves. That's the entire point of cops carrying badges--so people can properly identify them, their jurisdiction, and their activities as being official uses of tax dollars and community resources, and to report them if there's a problem.


"Why should they identify themselves
if they're not police?"

If you think that's never going to change,
I have a bridge in Brooklyn I want to sell to you.
Instead, investigators have hired professional genealogists like CeCe Moore through Parabon, a consulting agency who specializes in forensics. This changes the legality of what is being gathered and used by law enforcement, since the agents themselves are not the ones gathering and interpreting information from the database. No court order or warrant is needed.

And that may be completely legal in the sight of the law. But there is still something to be said for a certified, professional genealogist using the research and samples of others in a criminal investigation--without directly asking for and receiving informed, written consent BEFORE their information is used.

Before a professional genealogist hired by law enforcement ever puts my kit number into a One-to-One analysis with a known rapist/serial killer, I want my name on a signed legal document saying I gave them permission to use my data in that way. Before you submit my tree and a positive connection to my DNA sample as evidence in a criminal investigation, let alone a criminal trial, I deserve the ability to give or revoke my consent from you. I deserve a say in what your choice could do to my name, my family, and the way my work and identity becomes part of that case in the public record.

For those appealing to the GEDmatch Terms and Conditions in this situation, let me be perfectly clear and upfront with you: I don't care what the GEDmatch Terms and Conditions say. Especially since the Terms and Conditions exist to establish legal permissions and consent between me and GEDmatch, not me and the rest of the world who shows up there.The Terms and Conditions on that website do not invalidate my personal legal rights in the state and country where I live.

Legal behavior is not the same thing as moral and ethical behavior. Professional genealogy, like the professionals in any other industry, have ethical standards they agreed to abide by when they were certified. And if those ethical standards don't reflect how a genealogist should behave in their relationships with law enforcement, perhaps it's time for those ethical standards to be reexamined and expanded.

Note: Jeff Goldblum is one of only a handful of people who doesn't end up eaten by dinosaurs in this scenario.

Always listen to Jeff Goldblum.


Hobbyists as the Legally Admissible


In the realms of "genetic genealogy," there still are no certified professionals or a certifying body to speak of. While there are certifying boards for traditional genealogists, there is no such equivalent for genetic genealogy. It's a new frontier to all of us, which I don't think enough of the general public understands. We're all still figuring out what that means and what it should look like, especially as we are catapulted into the future by the popularity of commercial DNA testing by the masses.

GEDmatch wasn't created by "professionals." It was created by hobbyists, for hobbyists. Curtis Rogers is a businessman from Florida, and John Olson is an engineer from Texas. Neither one of them is a professional genealogist, from what I can tell. (Please correct me if I'm wrong about this and I will correct it in the post.) It was only very recently that GEDmatch even started taking money for their services. And I question any judge who, being familiar with the age and operational history of this website, would allow their matches and services to be considered legally admissible in court.

GEDmatch's creators being hobbyists DOES matter. Being hobbyists is going to be reflected in the operation they run. It's going to be reflected in the security of the platform, the quality and reliability of the matches being produced, and the administrative decisions being made on behalf of their users. And it matters that we examine each of these now that GEDmatch is becoming a tool to find and catch criminals.

Is the GEDmatch database secure enough not to be manipulated by outside attackers, who may want to manipulate or change the data in the system to misrepresent relationships between people? I don't know the answer to that question. But I don't think law enforcement officers do either.

With that question comes another that is very closely related, regarding professional standards of identification and accuracy. Just because a website links two people together and says they're related doesn't make it true. Likewise, just because it says they're not related doesn't make it true. What is the foundation, the reliability of those claims? Because you can't point to any formal qualification that the founders at GEDmatch have for two reasons--because they either don't have them, or that information isn't available for consideration. Their personal information and backgrounds are not posted anywhere on GEDmatch that I can find. (Someone please advise me if this is incorrect or if it changes, and I'll change the post to reflect it.) According to his Facebook profile, Curtis Rogers received his MS/MBA from either Denison University, Michigan State, or Berry University. I can find only credit mentions to John Olson for utilities that he implemented into the website.

In terms of exploring who else may be on the GEDmatch team, I've found two additional names: John Hayward and Blaine Bettinger. John Hayward has answered support questions to users, which suggests he has administrative capacities on the website and can make changes to its matching operations. Blaine Bettinger is a professional genealogist with a PhD in Biochemistry and Molecular Biology, and is affiliated with GEDmatch in what has been described as a legal capacity. To what extent he consults or provides any additional expertise to GEDmatch is not something I can comment on, because I don't know the answer.

And to be clear, I'm not trying to accuse the GEDmatch team or any individual person on it of being guilty of some kind of oversight or negligence, or being untrustworthy in any way. How can I, when I don't even know who they are, and I've had to search through news articles and forum posts to find what little information I now possess? But I think pointing out this lack of transparency is important, in the event that legal action becomes necessary for users who may be injured in some way by using this site. It may be legal for the team at GEDmatch to conceal their identities from the website, thereby making it difficult to hold them accountable for potential oversight or negligence on their part. But is it an ethical thing to do?

Just this week, I came across an example of a woman whose brother was given the same GEDmatch kit number as another user on GEDmatch. She thought she had a niece she knew nothing about, when in reality the GEDmatch website was presenting match information to her that simply wasn't accurate. It led her to confront her family with false allegations regarding the paternity of this woman, based entirely on a relationship presented to her by GEDmatch. Fortunately, the error was "immediately" corrected by GEDmatch, according to the woman involved.

While no website is completely free from human error 100% of the time, how often do these errors happen on GEDmatch? Does anyone actually know? Do the people behind the scenes at GEDmatch know? What is their turnaround time on mistakes like these? Do they have systems in place to find and correct them? And does this administrative error overlap with certain minority populations--like Jewish and African populations--being more susceptible to Identical by State (IBS) false positives?

I'm not saying any of this has happened in the criminal cases being worked by the genealogists on the Parabon consulting team. I can't possibly know that. I do know that certified professional genealogists are well-trained, and their work deserves respect. They are qualified to be legal experts in the tracing and documenting of familial relationships. And I trust the professional genealogists in this community to recognize and work around the weaknesses of tools like GEDmatch to the best of their abilities.

If we learn nothing else from Karen Keegan and
Lydia Fairchild, it should be that DNA doesn't lie...

But we don't always understand the story it's telling us either.
But genealogists, professional or otherwise, simply cannot account for all the errors in the tools they use. Those errors exist on every platform, to varying degrees and for a variety of reasons. And to be honest, I don't trust law enforcement agents, legal professionals, juries, and the general public to understand those limitations with enough nuance to prevent people from being falsely accused, based on what a DNA match on the internet allegedly says.

Before more cases are subjected to the matching abilities of commercial websites (and third-party websites like GEDmatch), there needs to be a unified standard for DNA matching, and for the consistent performance of algorithms to make positive, accurate matches without false positives. There need to be policies and protections in place to consider and recognize when DNA is not foolproof. We need a greater cultural awareness beyond the familiar adage that "DNA doesn't lie."

If we learn nothing else from Karen Keegan and Lydia Fairchild, it should be that DNA doesn't lie. But we don't always understand the story it's telling us either.

I would trust the technology from GEDmatch to tell me my mother has a half brother we had no idea existed. I would trust it to help me find and identify the birth fathers of my grandmothers. I have/would trust it to back up genealogical claims in low-stakes situations that few, if any other people outside of my own family are ever going to care about or be affected by.

But I wouldn't stake my life on GEDmatch, or the life and death of another human being on it--as will no doubt be the case in some of these trials. And I defy anyone who has used GEDmatch when more than 400 people are on it at the same time to tell me they would trust a human life to any assertion made by that website.

I expect inconsistent performance, and even mistakes, from a website I know is run by volunteers--who created this website as a service to help bring hobbyists together to do genealogy. I don't expect it from a website whose performance is going to be treated as legally admissible in a court of law for a criminal murder trial. GEDmatch may have access to a wide variety of user-submitted data from multiple testing companies. But should they be on the same legal footing with those testing companies, who have more resources and employees to guarantee consistent results in presenting reliable, accurate claims about relationships between people?

What qualifies GEDmatch, their founders and their current team as presently constituted, to occupy that position in someone else's criminal trial?

You'd think with me asking these kinds of questions, I want to see murders and rapists go free. I want exactly the opposite of that. I want the right person, who is guilty of the crime of which they stand accused, to be convicted and sentenced to a punishment that fits their crime. I want the law enforcement officers in charge of those investigations to use legal, ethical means to gather information and vet suspects in their investigation. I want eyes on the future in terms of dangerous legal precedents that could lift up a system that is too quick and hasty to judge the falsely accused. I want fairness and justice under the law for everyone. And I'm speaking up because I fear we're on the cusp of creating an international situation that is not in keeping with those values.

If we've learned nothing from #MeToo stories, can we please acknowledge how notoriously difficult it is to convict a rapist? Any weakness in the defenses and the bastard walks free. I'm not saying all of this because I want that to happen. I'm saying this because I think it will. It inevitably will if part of the foundation of evidence can not stand up in court due to it being declared inadmissible. (If you're interested in reading more about the admissibility of DNA evidence in court and all the powers that will be at play in these trials, I recommend reading this and this.) Inadmissible evidence is how criminal cases fall apart, and families who thought they were going to receive justice for unspeakable violence do not get it.

I'm saying all of this because I know how that feels. I know how it feels to watch a man who deserves to be punished walk free when he should be in prison. I know the games that lawyers play with evidence. I couldn't bear to see that happen, and to see GEDmatch at the center of it. As genealogists and as citizens, regardless of where we live, we all deserve better than this.

And if the legal precedents that are already being established by these cases don't disturb you, it's because you're not thinking concretely enough about the future they could lead to.


Civil and Constitutional Rights


Imagine a world where law enforcement agencies want a universal DNA database of all citizens, for the purpose of criminal investigations. Imagine if they had to publicly petition for the existence of that database. Imagine if they had to go to the legislators in their respective communities and countries, to publicly justify the existence of such an assemblage of human data.

Imagine the outrage people would have to that request. Imagine the legal and ethical conversations we would be having about many of the points I've already raised. Who should keep such a database? Who would maintain it? Who would keep it secure? Who would have jurisdiction over it? Who could access it? What kinds of legal permission would they need? How does using such a database violate or co-exist with (in the US) our 4th amendment due process rights, and our legal protections against "unreasonable searches and seisures"?

"It'll never happen," I've heard people say already. The sheer scope of the obstacles to be overcome is what they always appeal to. No one in their right minds would trust law enforcement agents to respect those rights when they have unrestricted access to DNA. Why bother with warrants when you could just pop a DNA sample into a computer and know exactly who it belongs to? The people who have no problem with this picture tell themselves, "if the person is guilty, why does it matter?"

Because when law enforcement agents do this, it's not just a justified search for one person. It's a warrantless, undocumented search against everyone else in the database. Everyone in that database is a suspect, over and over again, until the DNA says they're not. There is no presumption of innocence. There is no consent. There is no accountability to how and why that system might be manipulated--either from without or within--to make the database reflect whatever anyone with access to it wants it to say.

By allowing law enforcement agents to use GEDmatch to solve cold cases, we are one step closer to living in this reality. The genetic genealogists involved in researching these cases are on the front lines of giving away a DNA database that isn't subject to warrants and court orders. It's a threat to our rights against "unreasonable search and seizures." And that behavior is being normalized at the expense of users, many of whom are from an older generation who is deeply uncomfortable with technology. They may not understand the legal consent they are giving by participating in GEDmatch, or even the very act of when they gave consent by clicking on a check box.

Their consent may be legal, but in many cases it is not informed. It cannot be considered ethical. And it angers me to know that if many GEDmatch users truly understood the situation they were in, the future they are helping to create, they would likely want to remove themselves from GEDmatch. And they may not even have the necessary technological understanding to remove their information from the website, thereby revoking their consent.

The entire reason for reading or reciting a person's rights at the time of arrest is so they understand the boundaries of their relationship with law enforcement agents. We do this because we care about people being able to make informed decisions about their conduct in relation to police and their investigations. But being informed in this way isn't just necessary for those accused of crimes. It matters to everyone, including witnesses or assistants to any kind of formal investigation by law enforcement.

We deserve to have our rights explained to us in any interaction with police. How can we expect that when the officers involved in these investigations never show their faces to us, don't identify themselves, never speak to us directly, and use intermediaries that purposefully circumvent our legal protections under the law?

If you're okay with assisting law enforcement in the United States with their cold cases and criminal investigations, feel free to stay on GEDmatch and not take any additional action.

For the rest of us, we need to understand, in no uncertain terms:

By participating in GEDmatch, you agree to let anyone with access to the website use your public DNA match results in whatever way they want. GEDmatch is not going to attempt to limit, stop, or control the behavior of their users--even if that behavior is unethical, immoral, or in violation of your legal rights. They have absolved themselves of any and all responsibility for how the data on their website is being used, or may be used. They will not legally defend or protect you as a user. Your presence there is your sole legal responsibility.

If you are a citizen in a country outside the United States, and you upload your results publicly to GEDmatch, you give consent for them to be used in an untold number of criminal investigations--outside of the local and national jurisdictions where you live. Even if you are not a positive match to someone accused of a crime, your results are going to be used by an algorithm to narrow down the people who are. And if convicted, those who are accused will likely receive the death penalty or life sentences in prison, regardless of your personal or ethical feelings on those forms of punishment.

I've already changed my relationship with GEDmatch in response to this situation, and I will be doing follow-up posts to help you understand your options going forward.

If GEDmatch is going to let anyone in through an unguarded revolving door and leave with anything they want, it's not a safe place for its users to save money on additional DNA testing anymore.

And now I'm beginning to wonder if it ever was.

Downloading Your Raw Data from AncestryDNA



If you've tested your DNA with AncestryDNA, you might be wondering if you should invest even more money taking additional tests from other companies. If you're looking to find someone, or the answers to a very specific question, it can make sense to fish in as many ponds as you can access?

But why not see if the matches you're looking for are already available without having to spend that extra money?

That's where GEDmatch.com comes in. Because people from various testing companies have uploaded their results there, it's like taking multiple DNA tests for the price of one. And since you have upload your results there yourself, the people you reach out to are looking to make connections and actually write back to you!

But before you can upload your results to GEDmatch, you have to download your raw data from the AncestryDNA website first. And with this video, you'll know exactly where to go, what to click, and how to get the data that rightfully belongs to you.

Uploading Your Tree to GEDmatch

GEDmatch has become an essential tool to everyone who is serious about genetic genealogy. I'm not sure how many matches you have there. But the last time I saved my match list as a PDF, it was 23 pages long. And the last time I checked, the last page of matches stopped at about 10 cM. As more people take these tests and upload their raw data to GEDmatch, making traceable connections to our distant cousins becomes easier every day.




But are you taking full advantage of everything GEDmatch has to offer you? If you don't have a tree uploaded, the answer is "No!"

Why You Should Have a Tree on GEDmatch


In order to take full advantage of what genetic genealogy has to offer, you need three types of information:

  1. Segment data
  2. A tree
  3. Shared matches
I like to compare this to a car. In order for a car to function, at the bare minimum it needs wheels, an engine, and a fuel source. Without any one of those elements, the car simply couldn't move. In genetic genealogy, these same three elements are THAT fundamental. Some testing companies create this data scarcity by not providing tools to convey this essential information to their users. And given that some of the newest testing companies are gravitating away from this bare minimum, it leaves some newcomers in our community at a disadvantage.

Whenever a testing company has refused to offer one of these necessities to its customers, GEDmatch has been the equalizer. AncestryDNA won't provide segment data? GEDmatch will do that. MyHeritage DNA won't provide segment data or shared matches? GEDmatch will do that. That same capacity for tree sharing is also available. The ability to cross reference people on all of the sites on which they've tested is there. But how many of us are taking advantage of it?

I've used trees on GEDmatch to match users there to their original testing companies. Once I know I have the right person on AncestryDNA, their shared matches become a powerful finding tool. I compare those shared matches to what I know about the segment data. A much clearer image of the relationships at work in my DNA begins to emerge. It makes my job on GEDmatch AND AncestryDNA easier. And when I invite these shared matches to upload to GEDmatch, and they accept that invitation, documenting and preserving this record becomes possible.

How to Upload a Tree to GEDmatch


Now that I've been focused on linking GEDmatch users to their original testing companies, I'm noticing a trend. Many who provide trees at their original testing companies haven't done so on GEDmatch. Some of these users may not realize the capability to add a tree exists, or how to do it. So I've made a video for our YouTube channel to explain the process.




The trees they produce are not fancy, by any stretch of the imagination. But they provide needed information to the discoveries we're all trying to make. If you haven't uploaded a gedcom to your GEDmatch kits, be sure to add one today!

10 Tips for Making the Most of GEDmatch.com

I'm not really shy when it comes to how much I love GEDmatch.com, the open-source tool for anyone who has taken a DNA test for genetic genealogy. And really, what's not to love? I get matched up with relatives from all of the major testing companies, for free, without having to take or pay for multiple tests. It presents me with all of the segment information for my matches, and gives me the tools to analyze and work with my own results. I can decide for myself what matching criteria I want to use. Without GEDmatch, my experience as a genetic genealogist would be controlled and limited by corporate interests and objectives.




A downside to GEDmatch is that it has a steep learning curve. I've been using the website for several years now, and I'm still discovering new ways to use it all the time. To say nothing of all the ways I could be using it better. So in the spirit of helping us all to make the most of what GEDmatch has to offer, here are some of the tips that are making life a little easier for me.

1. Use Internet Explorer


I know. Let's party like it's 1999, right?
I'm not an expert on the technology behind web browsers, what makes them work, and why it matters which ones you use for which site. All I can tell you is what I've seen on my computer, in the hundreds of times I've used GEDmatch over the past several years. The sum of all that experience has shown that Google Chrome is the browser most likely to time out, crash, or just not load at all. Firefox is hit or miss, depending on the number of users on the site.

The only browser that consistently loads GEDmatch for me, regardless of the time of day or function I'm using, is Internet Explorer.

2. You Can Identify the Testing Company from the Kit Number


Am I the only person who didn't know the letter in the kit numbers corresponds to testing company? A is for AncestryDNA, T (and previously F) for Family Tree DNA, and M for 23&Me. (I recently saw an H, which I'm assuming is for MyHeritage.)

3. Printing your One-to-Many Match List as a PDF


In order to view all of the cousins and relatives that match with you, you have to load them all onto a single page. Called the One-to-Many list, this page takes the longest to load, and is the first thing to stop working when the site gets busy.

Rather than loading this page over and over again, print your results as a PDF document. That way, you can reference all of the information on it without creating extra strain on the site.

4. Sorting the Match List


Another feature I discovered by accident, you can actually sort by different columns on the One-to-Many match list. By default, it sorts by Total Autosomal DNA. Because of the way I sort and organize my data, however, I prefer to view it by Largest Segment. Every time I load the page, it's the first thing I change. But depending on what you want to view, you can reorganize the page and save a PDF of that version

This is especially useful when you want to create a match list of your X-DNA matches. By sorting with that column, your match list will load with a completely different set of matches. Based on the experience I had processing these matches for the first time, GEDmatch doesn't include all of the X-DNA matches on the default match list. The only way to see all of these matches is to use the sort arrow in that column. Keeping a separate list of these matches as a PDF is also helpful.

5. Use the X-DNA One-to-One Analysis


Speaking of X-DNA, which I also discovered in the past week, let me eliminate some confusion. X-DNA is Chromosome 23, and determines gender. It is not the same thing as mitochondrial DNA, which is inherited from your direct maternal line only. X-DNA is inherited by both men and women, and follows different inheritance paths according to gender. Being female, I inherited an X chromosome from my father, and my mother. My father got his X chromosome from his mother, and back through several different men and women along her lines. My mother, however, got her X chromosomes from a much larger collection of male and female relatives from both her paternal and maternal lines.





GEDmatch provides X DNA matches and analysis. If the only tools you ever use are the default match list and the general One-to-One analysis, you might not know that. There is a separate One-to-One utility for X DNA matches, which is the only one that will display those results. For relatives that share both autosomal and X DNA with you, you'll have to run their kits through both One-to-One match utilities to see all of the segments they share with you.

6. There's a Facebook Group!


Do yourself a favor and join this Facebook group. When I was first starting out, I had to ask a lot of questions that, looking back, I realize were really basic. The people there didn't have to take the time to explain such fundamental stuff to me. But they did, and it has made all of the difference in the choice I made to stick it out until I could understand. And they helped me without making me feel stupid, which is always an awesome thing.

7. STOP UPLOADING MULTIPLE KITS FOR YOURSELF!


To do DNA analysis, you have to process and compare literally hundreds of pieces of unique data. It's time-consuming and slow. From GEDmatch alone, I've processed over 1,500 samples. And I still haven't made it through half of the 23 pages of matches GEDmatch has to offer me. Let alone all of the matches on other websites I haven't gotten to yet. I may actually die before I process them all. And I know I'm not unique in that respect.

The number of people who upload duplicate kits for themselves, especially when they don't make it obvious, does a disservice to everyone. They take up precious space on the site servers with duplicated information. They waste everyone else's time in processing extra samples for the same person. And as much as I hate this behavior, I can at least understand it if you upload results from different testing companies. I seriously wish you wouldn't. But I get it.

But y'all who are uploading duplicate kits from the same testing company. Why? WHY?! What did you think it was going to tell you the second, third, fourth, or fifth time that it didn't say the first time? And before you think I'm blowing my stack about nothing, I'm not making this up. I have seen multiple people in my match list upload as many as five kits for themselves, and they're all from the same testing company.


I'VE HAD IT WITH YOUR CRAP SANDRA!

Just stop it already!

(Note: You can tell if it's a duplicate if you do a One-to-One comparison with the Graphics turned on. The bars that show up will be solid blue and green)

8. Link Your Kit Number and Tree Together


DNA segment data isn't useless without a tree. Certainly adoptees have had to make do with less. But everything about genetic genealogy is so much easier with a tree. So the more you do to connect your GEDmatch kit number and your online tree together, the better.

I post my kit number all over the place. It's on my blog, in my Ancestry.com profile, and on my Find a Grave profile. On Twitter, I put my kit number in the location field of my profile. I made a graphic of my kit number with a template on Canva.com. Then I set it to be a Featured Photo in the sidebar of my Facebook profile. You can also share it on Instagram, Pinterest, and other forms of social media. Put your kit number anywhere a relative might see it, and who knows? Maybe one day, it'll pay off.




I only wish it were that simple to link to our various online trees on GEDmatch. While the site allows people to upload gedcom files, the interface is dated and limited. It doesn't display any source information, and does nothing to connect users to their profiles or trees from their original testing companies. Links to online trees, usernames, and testing company user profiles would be much more useful, in terms of building bridges between trees and segment data. I'd love to see that in future builds for the site.

9. Tell Your Cousin Matches About GEDmatch


Whenever I contact cousin matches on AncestryDNA, I tell them about GEDmatch. I always send along my kit number, in case they're already users. If it's someone I'm particularly interested in connecting with, I tell them they can access more free matches from other testing companies at GEDmatch. Quite a few people have taken me up on that invitation, and some of my best matches are with people I've introduced to the site.

GEDmatch exists entirely from word of mouth. Everyone who uses it heard about it from someone else once upon a time. If we want the site to keep growing, we have to keep telling people about it.

10. Do Descendancy Research!


When I took my DNA test, I thought it was going to tell me who my ancestors were. Now I see that isn't how it works, at least not directly. The thing DNA tests are best at is connecting me to other living descendants of my ancestors. It's up to us to figure out where the connection is through collaboration and traditional research.

Since cousins and distant relatives are primarily what my test gives to me, it makes sense to spend time researching who they are. The more you know about the descendants of your ancestors, the more easily your will recognize them when they take a DNA test. Since most of us start a new tree with only biological ancestral connections anyway (or at least you should!), it makes sense to include descendants on that same tree.

When your biological tree becomes a more complete record of every person who is biologically related to you, the more DNA testing will reward you for those efforts.

Learning to use segment data can seem like a daunting task. It requires an investment of time that some of us may question. Is the value of what I've going to get back in the end worth the time I'm taking away from traditional research? I know that was a question I once had. I know it's a question that many people ask themselves before and after taking a DNA test. Is it worth the time and money I'm about to spend on it?

Even as many are asking themselves those questions, they still underestimate the investment that goes into doing genetic genealogy well. There truly is no royal road to geometry, no easy way to learn to use DNA, and no credible way to make it easier. We all have to pay what it costs to achieve understanding.

Your DNA Cousin Match Database: Getting Started with my Excel Template

A reader from a recent post requested a template for setting up a DNA matching database. Because it's quick and easy to set one up in Excel, I threw one together quickly. Please feel free to reuse for non-commercial purposes, but not to repost.






When you open this file, it's going to be a View Only file in my Google Drive. In order to use it yourself, you need to download it. The link to do so is on the top right corner, next to the Print option. You'll then be free to use it in Excel, or with whatever other spreadsheet software you want to use that is compatible with Microsoft Excel.

I've got the Filters already set up and enabled, which means you'll be able to sort and filter information when you analyze the data. In order to see those matches with the greatest similarity/longest segments, sort your Segment Length column from largest to smallest. If you want to see the other matches that might also connect to a given cousin on the same chromosome, sort the Starting or Ending Point from largest to smallest. Reading the ranges between these two numbers, determine where there may be overlap. Use the matching utilities from your testing company or analysis website of choice to determine whether a match exists. Record your findings in your Notes section. If you're able to determine who the common ancestor(s) are that you share with a match, record that information in the Most Recent Common Ancestors (MRCA) column.

If you decide you want to move different columns around, or add more columns, I recommend turning off the Filters (highlight headers, Data > Filter button toggled off), changing things around, then turning the filters back on.

If you use the table in Excel, I've frozen the column headers, so they continue to show up as you scroll down through the data. To enable or disable this option, highlight the headers, go to View > Freeze Panes > Unfreeze Columns, Freeze Top Row, or Freeze First Column, according to what your preferences are. I don't know if this option works in Google Sheets or not, or in any other spreadsheet software. So bear that in mind.

However, now that I'm seeing this open in Google Sheets, I think anyone who decides to use this may want to consider using it there. Not only will this allow you to access your spreadsheet from multiple devices at once, the layout of the file itself is much nice in Sheets than in Excel. Because of the way Excel scrolls the tabs across the bottom of the screen, you have to click through a series of tabs over and over again to get from Chromosome 1 to Chromosome 22. In Google Sheets, however, all of the tabs display across the bottom without any of them being hidden. This may not be an issue, depending on the size of your monitor or display resolution. But definitely check around to see what you like/makes your life easier!

Free DNA Discoveries from GEDmatch.com



DNA testing is among the many technological revolutions taking place in the genealogical community. With a little help from AncestryDNA, 23&Me, and Family Tree DNA, you can connect with other descendants of your ancestors to increasingly remote corners of the globe. By collaborating with them, many genealogists are tearing down long standing brick walls and making incredible discoveries.

However, there are limitations to genetic genealogical testing--and not just the 8 generation window the technology gives us at this present time. These limitations instead come from expense, and the boundaries between testing companies. If the descendants to whom you need to connect have tested with a different company than you have, you may not see that match until one or the other of you takes a second test with the right company.

But does it have to be that way? In our day and age of open source software and good digital citizenship, there are no necessary boundaries between testing companies anymore.

Introducing GEDmatch.com

GEDmatch.com is a website which allows users from each of these testing companies to upload their DNA test results. No matter where you live or which of the testing companies has performed your test, GEDmatch.com is free for you to use. You are then placed into a database, which includes users from each of the major testing companies.

Learning to use GEDmatch requires a little more than the average sit-down to learn how to use it. Because of that, we've provided a beginners guide with our Genetic Genealogy video series. This final video in that series provides a beginners introduction to GEDmatch, and the three most essential tools on that site: the One-to-Many match list, the One-to-One analysis, and the Admixture utilities.

Have you taken a DNA test and are still waiting to make the right cousin match? Check out GEDmatch.com and see what you can discover today!
