2025 Genetic Genealogy Retrospective: Wow – What a Year!

2025 has been quite a year in genetic genealogy. Genetic genealogy, per se, really isn’t a separate “thing” anymore. DNA testing is now an integral part of genealogy, with the potential to answer questions that nothing else can!

The 76 articles I wrote in 2025 fall into multiple categories and focus on different topics based on what was happening in the industry.

From my perspective, here are the most notable announcements and trends in genetic genealogy, and genealogy more broadly.

#1 for 2025 – Mitochondrial DNA: The Million Mito Project Released the New Mitotree, Updates, and mtDNA Discover

The biggest genealogy news items this year, both industry-wide and genealogy-changing are definitely the release of the new Mitotree, plus two tree updates. But that’s not all.

In addition, full sequence mitochondrial DNA testers received new Mitotree haplogroups, if appropriate, and everyone received a haplotype – a new feature. Along with Mitotree, FamilyTreeDNA introduced mtDNA Discover which provides 13 individual reports based on your haplogroup and matches.

It’s no wonder that mitochondrial DNA articles led the pack with the most views based on the eleven articles about that topic. If you haven’t yet tested your mitochondrial DNA at FamilyTreeDNA, there’s no better time! You never know what you’re going to discover and the more testers, the more matches for everyone.

You don’t know what you don’t know, and you’ll never know if you don’t test. Remember, mitochondrial DNA is for both males and females and tests your mother’s direct matrilineal line (mother to mother to mother, etc.) – reaching beyond known surnames.  Click here to order or upgrade.

#2 – MyHeritage Low Pass Whole Genome Sequence Test Charges into the Future

Another big hitter is the new MyHeritage low-pass whole genome test (WGS) test. It’s new and innovative, but we haven’t seen comparative results yet.

My results from the new low-pass whole genome test just came back, and I haven’t had the opportunity to review them yet, as compared to the earlier tests. That said, I do have roughly the same number of matches, but I need to determine if they are the same matches, and how well they track. I’ll be working on that review soon.

The new whole genome test may be more about future proofing and preparedness than additional current benefit – but we will see. I definately wanted to take the whole genome test so I can receive and benefit from whatever new is coming down the pike.

MyHeritage allows you to maintain multiple DNA tests on your account, so the new whole genome won’t “replace” your older or uploaded test. That way, you can easily compare the results of the whole genome against any DNA test that you curently have at MyHeritage.

#3 – 23andMe Experiences Problems

On a less positive note, but still quite newsworthy is the bankruptcy of 23andMe and subsequent repurchase of 23andMe by the original founder after setting up a new nonprofit. I have real mixed feelings about this topic. However, 23andMe was really never about genealogy, and now, matching segment information is no longer available. Those searching for unknown parents or family may want to test there if they are unsuccessful elsewhere.

Best Genealogy Tool

The FamilySearch full text search continues to have a HUGE impact for genealogists. This tool is not one-and-done, but provides increasing amounts of rich information as more records are added to the “fully scanned” collection. If you haven’t tried it, please do. It’s a game-changer and continues to improve.

A Cautionary Word About AI – Artificial Intelligence

AI is such a hot topic right now that I feel it needs to be included.

The FamilySearch full text search uses a form of AI. However, you’ll quickly notice that it can’t read everything, gets words and names wrong, and if you actually need to fully depend on it for accuracy, you cannot. (That said, it’s still an amazing tool, and I’m not picking on FamilySearch.)

Aside from FamilySearch, AI in its current form is both wonderful and terrible. I’ll be writing about AI in the new year, but for now, don’t ever rely on AI for anything that you can’t verity. It’s your assistant, not an expert, no matter how insistent it is. Never trust and always verify.

This is ESPECIALLY TRUE WHEN RELATED TO GENETICS and genetic related topics. I can’t even begin to tell you how very wrong it has been, and how much people fall in love with inaccurate results. No, just no – at least for now.

You need to know your AI tool, your skill set, your understanding of AI broadly, the tool’s limitations, and yours, and that’s all before verifying the actual AI results. If you want to educate yourself, and everyone should, treat yourself to anything, anyplace by either Mark Thompson or Steve Little, the dynamic AI duo. They offer YouTube videos and classes in a wide variety of places – but keep in mind that AI tools and technology literally change every few weeks.

AI is, indeed, a specialty all unto itself, much like genetic genealogy. And right now, it’s not soup yet, but it is cooking.

Tried and True Genetic Genealogy Staples – DNAPrint and Genetic Affairs

I haven’t written about either one this year, but I use both DNAPainter and Genetic Affairs regularly.

I consistently paint segments from matches at both MyHeritage, FamilyTreeDNA, and GEDmatch that are newly identified to an ancestor or ancestral couple at DNAPainter.

Unfortunately, neither Ancestry nor 23andMe provide matching cM location information for your matches (chromosome browser), but you may find some people who have tested at those companies at both FamilyTreeDNA and GEDmatch if they have uploaded to either of those vendors. Both vendors provide segment information and a Chromosome Browser, enabling you to paint that information to DNAPainter when you can identify your common ancestor.

MyHeritage also provides a Chromosome Browser, but unfortunately, no longer accepts uploads from any other vendor. You can paint segments from MyHeritage, but no longer upload DNA files to MyHeritage.

Thanks to DNAPainter, I have 90% of my segments identified to specific ancestors – which is actually rather remarkable given that my mother’s grandfather was a Dutch immigrant, and her great-grandparents on her other side were German immigrants, meaning we don’t have many matches on either of those lines.

Genetic Affairs continues to develop new, advanced clustering tools, one of which I’ll be reviewing soon.

Major Vendor Releases

Aside from what’s listed above, most of the major vendors released new features.

MyHeritage released a VERY COOL new tool called Cousin Finder that finds your relatives in the MyHeritage database, whether they match you on a DNA test, or not. They may not have even taken a DNA test. Cousin Finder identifies your common ancestor and shows your relationships. It’s a wonderful way to initiate communications, discuss your common ancestors, and ask about DNA testing.

Of my 378 Cousin Finder matches, only 23 (about 6%) are on my DNA match list, so that leaves 355 people to message, several of whom represent Y-DNA and mtDNA lines I don’t have. You can bet I’ll be offering testing scholarships.

Additionally, MyHeritage released a new ethnicity version.

FamilyTreeDNA, in addition to the new Mitotree, Discover, and associated features, released a new match matrix so you can see if and how selected matches are related to each other in a grid format. In other words, you can create your own cluster.

A new built-in “Share” feature blurs private information to make sharing easier both on the website and in Discover.

Discover improvements include thousands of new Y-DNA and mtDNA tree branches, plus thousands of new Ancient DNA samples. Discover is evergreen, so once you’ve taken that Big Y-700 test or the mitochondrial DNA test, your learning never stops as more content is added.

Tree integration with WikiTree is super-easy and means you don’t have to choose between trees. You can choose to retain your archived tree at FamilyTreeDNA, or move your tree to MyHeritage, PLUS link yourself to your family at WikiTree.

Ancestry released match clustering and a new beta pedigree view of ThruLines, but that’s back in the shop for more work. I’d expect to see it rereleased in 2026.

Conferences

RootsTech is the granddaddy of genealogy conferences, and it’s always fun to attend and write about the experience. Many vendors release new tools or products during the conference.

The ECGGC (East Coast Genetic Genealogy Conference), held in the fall, is the only conference that focuses entirely on genetic genealogy, new tools, how to use existing tools, and more. The 2025 conference was virtual and provided a great deal of focused content. Attendees particularly appreciate the deep dive in a particular topic presented in DNA Academy.

I’ll be at RootsTech in 2026, will write about that soon, and hope to see you there.

Concepts, Techniques and Plain Old Genealogy

In the past, my Concepts series and genealogy “how to” articles have been very popular, so, in 2025, I penned a half-dozen articles focusing on frequently asked questions about relationships and DNA.

For example, how does one go about finding DNA testing candidates? The number of options may surprise you and includes both Cousin Finder and Relatives at RootsTech.

By testing ONE PERSON for either Y-DNA or mitochondrial DNA that represents an ancestor, you actually receive information about that entire lineage of ancestors. So, on my Estes line, by locating an Estes male from my line to test, I received relevant information for every Estes male in my line, back to and beyond the progenitor.

Eventually, we hit a brick wall in every line, and those tools are the perfect way to break through those brick walls.

Other articles discuss things like how to use Discover’s Ancient Connections, and the difference between half and full relationships, both in your tree and genetically. Plus, what does a cousin “once removed” mean anyway? And why do I care?

Another question I receive is how far back, based on the shared amount of DNA, should I look in my matches’ trees for our common ancestor? In other words, how many generations back should I click? That article was fun and produced some unexpected results.

Memorial Articles

Because we are part of a community, I write memorial articles when one of our friends passes on. This year, sadly, Schelly Talalay Dardashti, well-known Jewish genealogist, and another very close friend joined the ancestors, so I’ve recognized the best in both of their lives which constitutes their legacy.

Be the Storyteller

Last, but not least, I wrote about my ancestors in the “52 Ancestors” series, which launched several years ago with Amy Johnson Crow’s challenge to write about one ancestor per week. She hosts this every year, and you can join (free) now.

I’m now on ancestor #467, so yes, it’s addictive, but it’s also AMAZING how many wonderful cousins I’ve met who have information that I did not. Not only that, but after publishing about an ancestor, I’ve discovered that I’m related to people I’ve known for years. We were SOOOooo excited!

I’ve been writing about the lives of my ancestors for several years now, and the articles include attempts to identify Y-DNA and mtDNA testers for each ancestor, where appropriate. There’s so much to learn that can’t be revealed any other way.

Plus, people seem to like the “mystery” and “short story” aspect, and I salt each story with the history of the region and relevant historical events of the timeframe. You might find your ancestors here too, or other helpful information.

Find a way to share about your ancestors!

RootsTech 2025 – The Year of Discover and the New Mitotree

Last week, RootsTech was a whirlwind and full of discoveries – which, ironically, was the 2025 theme.

I always take you along with me and share the RootsTech experience, start to finish, so here’s my 2025 “feet on the ground” report.

I might, just might, have overcommitted myself. I taught the half-day DNA Academy,  three more sessions, plus several other commitments such as book signings, get-togethers, and interviews.

One class, “DNA for Native American Genealogy,” was a live webinar from the floor of the expo hall. You can watch that here for free, if you’re interested.

Unfortunately, none of my other sessions were recorded, but I’ll see what other alternative options may be available to bring those to you.

Additionally, I did two book signings at the GenealogyBank booth, along with two other authors, Drew Smith and Sunny Morton. I’m sorry, I don’t have any pictures. I should have asked someone to take some.

There were long lines and books sold out. Still, you can order either of my books, The Complete Guide to FamilyTreeDNA – Y-DNA, Mitochondrial, Autosomal and X-DNA or DNA for Native American Genealogy, at Genealogical.com. Thank you to GenealogyBank for being so welcoming.

The book signing was particularly fun because people shared their success stories or their hopes of what they want to achieve. I met a couple of new cousins too! Even people waiting in line were helping each other with information about research resources.

I had created my “RootsTech plan” for sessions I wanted to attend, but I was only able to actually attend one of those. Several were happening at the same time as mine, or directly before or after. As a presenter, you arrive early to get set up and make sure everything is working correctly.

Then, after your session, attendees have questions and are interested in your topic, which is a good thing. So essentially, you can’t attend sessions either before or after your session either.

Before I share photos, I’d like to share something else.

It’s About the People

I have never attended RootsTech for the classes, although there are wonderful offerings – and I have enjoyed them immensely.

Having said that, for me, the best part of RootsTech is the people. People I know and love but never get to see – many of whom I met in-person at RootsTech initially. I get to meet my blog followers. I meet with or reconnect with friends and cousins from around the world. I am privileged to talk with people about their challenges and their victories – when they’ve broken through a brick wall using DNA that they could never have otherwise achieved. People collaborating and helping each other. It’s all beautiful.

The reason I started blogging in the first place, and the reason all 1750 articles are free, is because I wanted to help people do just that – confirm ancestors, find ancestors, and connect with their fsmily.

My cousins that I’ve met through genealogy are some of my closest friends and closest family members. Outliving everyone is a mixed blessing but it makes me extremely grateful for my various cousins since all of my siblings and close family, with the exception of the next generation, have transitioned to the land of the ancestors.

So, yea, for me, RootsTech is about connecting and reconnecting with the people.

That’s also why I never get anything done because I’m always talking with someone.

Additionally, this particular RootsTech was a celebration.

Mitotree Release

Just a few days before RootsTech, the Million Mito Team at FamilyTreeDNA released the brand new Mitotree, 5 years in the making, reconstructing the tree of humankind to reflect our combined heritage more accurately.

At RootsTech 2020, I was honored to announce the Million Mito Project, and the new Mitotree initiative was born.

At some point, I will write about the deep, personal significance of the Mitotree for me,  but for now, suffice it to say that there is something profoundly moving about rewriting the tree of humankind and in doing so, giving a voice to our ancestors from long ago. Yes, I know many of them are thousands or even tens of thousands of years old, but had they not survived, we would not be here today. Now we can identify who they are and that they lived.

Million Mito Team, left to right, Goran Runfeldt, Dr. Paul Maier, me, Dr. Miguel Vilar, Bennett Greenspan, John Detsikas

Our amazing Dream Team has given life to our ancestors and said their names once again, even if their name is a mitochondrial DNA haplogroup. Four team members, Goran, Paul, me and Bennett were at RootsTech. Where else can you actually approach and speak with the actual scientists?

When I say RootsTech is about the people, I know that I am related to every single individual at RootsTech, it’s just a matter of how far back in time. So are you.

Just think about the significance of that for a minute.

Every. Single. Person.

The other end of the mitochondrial DNA spectrum is genealogy, of course, and the new Mitotree with it’s haplotype clusters brings mitochondrial DNA results into the genealogical timeframe. In future articles, I’ll be writing about each one of the new tools, what they mean, and how to use them.

Dr. Paul Maier, lead scientist doing most of the hard science behind Mitotree, had the much-deserved honor of introducing the Mitotree to genealogists at RootsTech.

I’m not sure the audience understood they were witnessing history unfold, but they clearly were. We needed a drum roll and some balloons!

This wasn’t like most vendor announcements of a new product or feature – this was a major scientific achievement that led to genealogical benefits.

In celebration, I asked my friend to make double helix zipper pulls so that I could give them to colleagues, friends and cousins that I ran into at RootsTech. It’s my way of celebrating and sharing the joy!

Five years is a very long time to work on a project. The Mitotree is a massive accomplishment. Every customer at FamilyTreeDNA who has taken the full sequence test received their new haplogroup either the week before or during RootsTech, AND, the second updated version of the tree was released too.

While this is truly wonderful, the true highlight is the testimonials – seeing how Mitotree is actually helping people break through their brick walls.

Here’s just one.

Breathless Testimonial

I’m going to try to convey this exactly as it happened.

A lady that I don’t know literally runs up to me in the hallway. This isn’t unusual. She was so excited that what she said was one long breathless sentence, which I’m going to try to reconstruct here, although I’m adding a bit of punctuation. I also can’t remember how many “greats” were attached to the “grandmother,” but you’ll get the idea.

Roberta, Roberta, I’m so excited – I just wanted to let you know – I found my ancestor using mitochondrial DNA. I got my new haplogroup and I had like 47 matches before but now they are clustered together so I could focus…and there were three matches in my cluster…and one of them had an EKA but the other didn’t…so I built out the EKA matches’ tree and guess what??? They were from the same place and then I found that her great-great-grandmother’s sister is my great-great-grandmother but she had her surname so now I have more generations too. OMG I ‘m so excited I could never have broken through this wall without mtDNA because I had no surname. This is THE MOST CONSEQUENTIAL DNA TEST I’VE EVER TAKEN, and I’ve taken them all. Thank you, thank you!

And with that she quickly hugged me and ran off to something she was obviously late for.

I never got to say one word, which was fine, but I stood there with tears in my eyes, thinking to myself, “This – this is what it’s all about.”

It doesn’t get better than this!

I want to hear your stories too. I just scaled my fourth brick wall last night using the new Mitotree and mtDNA Discover features.

RootsTech Week

RootsTech week started early for me – as in leaving the house at 3 AM Sunday. I fly on Sunday because the flights are cheaper and because the pre-conference meetings and events begin on Monday.

We took off into the dawn, jetting our way westward through the azure blue sky.

I have never gotten over the majesty and beauty of the Rocky Mountains.

And then, of course, the Great Salt Lake, for which Salt Lake City is named.

Looking at the Salt Palace across the street from the Marriott hotel. The silver building is the new Hyatt which is attached to the conference center behind the windmills which extends another very long block to the right, out of view. The mountain range is visible in the distance, and the beautiful sunset.

Speaking of the Marriott hotel, several people have asked if it was any better this year, and if I got trapped in the fire exit again, like last year.

No, I didn’t get stuck because I didn’t tempt fate again. It looked just the same though, so I’m presuming nothing has changed. Furthermore, there was no heat in my room, so they gave me a space heater and a pass to the concierge level – which they did not do last year.

That was kind of them, but food ran out, and there was only one poor server in the restaurant. I’m not even going to mention the nauseating thing that happened with my food. Let’s just say I’m not picky, but I will NEVER eat there again, and that makes it particularly difficult because there’s very little close by, especially when you’re exhausted.

I’m hoping that RootsTech will negotiate someplace different for speakers in the future. I’ve stayed in a lot of Marriotts and most of them are just fine. I have never had issues like this with any of them, let alone repeat issues year after year.

The good news is that we’re not there for the hotel, and the fun began on Monday.

Monday

My interviews began on Monday morning with “Mondays with Myrt” at the FamilySearch Library, which you can view here beginning about 16 minutes.

Mondays with Myrt is a RootsTech tradition and Myrt incorporates people present in person and tuning in virtually as well. Left to right, Kirsty Gray from England, John Tracy Cunningham, me and Myrt. Kirsty had a huge breakthrough that she shared with us just a few minutes after it happened.

I met John at the ECGGS Conference last October. He’s one of the few people I know whose 8 great-grandparents were born in the same county. I’m so jealous. Mine were either born in or first generation immigrants from four countries.

Sometimes the broadcast waiting area is just as much fun as the actual broadcast – in part because it’s the first day of RootsTech week and everyone is so excited to see their friends that they haven’t seen in forever. Call is a reunion!

Do Kirsty Gray and I look like we’re about to get into mischief?

Behind me is the first group of folks to be interviewed.

Pat Richley-Erickson, aka Myrt, Cheryl Hudson Passey, Laura Wilkinson Hedgecock, and Jenny Horner Hawran.

This is the livestream room at the FamilySearch Library. The waiting area for the next group is to the right, and the three presently being interviewed are sitting on the left beside Myrt.

For those who know Gordon, aka Mr. Myrt, he’s coordinating interviewees outside the livestream room. His job is herding cats and he’s the nicest cat-herder you’ll ever meet!

Pre-RootsTech Library Research

I love the FamilySearch Library. It feels like coming home to me.

So many passionate genealogists at every level – learning and searching. Lots of volunteer helpers available, too.

Normally, I create a research plan for the library, but I had been so utterly slammed between preparing my several RootsTech sessions and the Mitotree release that I hadn’t really been able to prepare anything.

I did, however, have a group of ancestors in mind that settled in the Oley Valley in Pennsylvania, so I decided to focus on the Berks County books.

I won’t bore you with the details, but among other things, I found confirmation that the Hoch surname is also the same as High and Hoy, which explains some very confusing Y-DNA results. So even though I didn’t get much productive time there, I did find something very useful in the land records.

I also ran into cousins and friends, of course, which is why I didn’t get more actual research done.

I knew Judy Nimer Muhn, at left, was going to be at RootsTech as a speaker, and I knew we connected through Acadian lines, but we never took the time to really piece together that puzzle.

My cousins, Mark and Manny were also coming for RootsTech, and to visit the library, for the first time. Mark, Manny and I visited Nova Scotia together in the summer of 2024, chasing our ancestors.

You know, fate is a funny thing.

We all descend from Acadian, Francois Savoie who was born about 1621 in France, but settled in Acadia, today’s Nova Scotia. Mark, Manny and I knew that we are cousins through Francois, but Judy and I did not. Mark, Manny and I ran into a local historian, Charlie Thibodeau, the Acadian Peasant, last year, outside of Port Royal. It just so happened that he was taking another couple to see the remains of the Savoie homestead deep in the salt marshes at BelleIsle.

We asked if we could join them, and Charlie was kind enough to include us. It was a long, brutally hot, tick-infested hike through the swamp, but oh so worth it!

We also found the well, located between three homesteads.

The year before, Judy had been in the same place in Nova Scotia, found the same man, Charlie, at the BelleIsle Hall Acadian Cultural Centre, and he had taken her to the remains of the same homestead.

And here we all four are in Utah.

What are the chances?

Needless to say, we had a LOT to talk about, and still do. Unfortunately, I wasn’t able to get to Judy’s talk, but Mark and Manny attended.

I ran into Katy Rowe-Schurwanz, the FamilyTreeDNA Product Manager at the library too, and look what she’s wearing – a mitochondrial DNA scarf. How cool is that!

The rest of Tuesday and most of Wednesday morning were spent trying to update my several presentations to reflect newly released information by various vendors and practicing the timing of the presentations. I had another interview, and more people were arriving.

I found time to visit Eva’s Bakery about 3 blocks from the Salt Palace. If you’re ever in Salt Lake City, Eva’s is a must! Lunch is wonderful, and so are their French pastries.

Wednesday is “tech prep” day at RootsTech, along with speaker instructions and then the Speaker Dinner.

Steve Rockwood, President and CEO of FamilySearch always delivers an inspirational message and this year did not disappoint.

If you’ve wondered about RootsTech conference stats, they provided this information. I can’t even imagine trying to coordinate all of this – and that’s not including the vendors, expo hall, technology in the presentation rooms, food, security and so much more.

Last year, in 2024, the final attendance numbers were more than 16,000 people in person and 4 million virtual attendees. I noticed a few days ago that there were more than half a million people participating in Relatives at RootsTech, which is still live until April 12th.

On Wednesday evening, after the Speaker’s Dinner, vendors in the Expo Hall were putting the final touches on their booths and preparing for the thousands of excited genealogists who would descend Thursday morning.

Discover

This year’s RootsTech theme was “discover” and attendees were greeted with this display just inside the door.

Attendees listed their discoveries on Post-its and could either post them on the board or plastic boxes, or on the green tree.

I placed my discovery from the day before at the library on the Rootstech tree.

Some people place their wishes here, kind of like a technology wishing well.

I couldn’t help but think of the new Mitotree, now forever green and growing, so I posted a second discovery, “Mitotree.”

Thursday – Opening Day

For those who don’t know, the Salt Palace Convention Center is two lengthy blocks long, a block wide, and two or three stories high, depending on whether you are in the front or rear portion. In other words, it’s massive and you need a map!

The huge Expo Hall with vendors is located in the center on the first floor and vendors have aisle addresses. The show floor is always very busy, and this year was no exception. One of the things I love is that spontaneous conversations just spring up between people who often find commonalities – common ancestors, common locations, and more. People compliment each other and join others at tables. It’s like a big family gathering of sorts.

I always try to walk the entire Expo Hall, because I really enjoy seeing the vendors and their wares, but this year, I never actually had enough time to traverse all the aisles. I took several pictures as I was passing through and running into people, but not nearly enough. I know I missed a lot, but there just wasn’t enough time and I arrived at RootsTech already tired.

However, the energy of RootsTech is like no place else and just infects you.

It’s like you can’t drink from the genealogy firehose fast enough!

Let’s Take a Walk

Ok, come along on a walk with me.

Left to right, Lianne Kruger, a speaker, and Courtney, in the FamilyTreeDNA booth. I believe they said they are cousins.

Daniel Horowitz, genealogist extraordinaire, in the MyHeritage booth. More about MyHeritage’s announcements shortly.

Geoff Rasmussen in the Legacy Family Tree Webinars booth. For those who don’t know, there’s lots of good material at Legacy, and the freshly recorded webinars are always free for a week.

Several vendors offer booth talks, including MyHeritage. I love their photo tools and use their site in some capacity almost daily.

One of the RootsTech traditions is ribbons. Collect one, collect ‘em all. Liv’s ribbons almost reach the floor. I think she wins!

Selfies are also a RootsTech tradition. Me, here with Jonny Perl of DNAPainter fame. I owe Jonny an apology as he asked me if I had a minute, and I had to say no because I was on the way to one of my own classes. I never got back to his booth to view his new features. Sorry Jonny – don’t take it personally!

Jonny released a new Ancestral tree version titled Places, so take a look here at his blog. I need to go look at my ancestors Places.

You’ll find this new feature under Ancestral Trees, Places. These are my most recent 8 generations. Just think of all those brave souls who climbed on a ship and sailed for the unknown. Check this feature out and have fun.

In a booth talk, Dave Vance, Executive Vice-President and General Manager at FamilyTreeDNA is speaking about the three types of DNA, which are, of course, Y-DNA, mitochondrial and autosomal DNA – all useful for genealogy in different ways.

Dave is explaining how in-common-with matches, also known as shared matches, operate with the chromosome browser. You can use the chromosome browser, shared matches, the new Matrix Tool, and download your match segment information at FamilyTreeDNA, a combination of features not available at any other vendor.

WikiTree, a free a moderated one-world-tree is one of my favorite genealogy tools. One of their best features is that you find your ancestor, and in addition to lots of sources, their Y-DNA, mitochondrial DNA, and those who are related autosomally are listed. Here’s my grandfather, for example.

Several DNA connections are listed. The further back in my tree, the more DNA connections are found, becuase those ancestors have more descendants.

WikiTree volunteers were wandering around taking pictures of “WikiTreers” holding fun signs.

Paul Woodbury, a long time researcher with Legacy Tree Genealogists, who specializes in DNA. I don’t take private clients anymore, and regularly refer people to Legacy Tree.

Me with Janine Cloud taking our annual RootsTech selfie. Janine, the Group Projects Manager at FamilyTreeDNA and I co-administer one of those projects and accidentally discovered a few years ago that we are cousins too. How fun is this!!!

I wanted this shirt, but by the time I got back to the booth, it was too late. I’m going to order it online from Carlisle Creations, in case you want one too. This is so me.

Land records are critically important to genealogists. Rebecca Whitman’s class was about plotting land plats. What she’s holding is a surveyor’s chain. You’ve read about chain carriers? This is what they carried to measure land boundaries – literally metes and bounds. Some of my best discoveries have been thanks to land records.

The only session I actually got to attend was Gilad Japhet’s “What’s New and Exciting at MyHeritage.” For those who don’t know, Gilad is the founder and CEO of MyHeritage and it’s always great to hear about the new features straight from the top executive who is, himself, a seasoned genealogist. That’s why he started MyHeritage in the first place – 22 years ago in his living room.

Gilad had several wonderful announcements, but the one I’m most excited about is their new Cousin Finder. Cousin Finder finds and reveals cousins who are DNA candidates if they have not yet taken a DNA test.

I’ll be writing more about the MyHeritage announcements soon, but you can read their blog about Cousin Finder now, here, and their Roundup here about the rest of their announcements!

My Last Class – Reveal Your Maternal Ancestors & Their Stories

My last class at the end of the final day of RootsTech was “Reveal Your Maternal Ancestors & Their Stories – Solving Mitochondrial DNA Puzzles.”

Had I tried to coordinate this presentation with International Women’s Day, I could never have done it, but fate winked and here I was.

I’m often asked what it’s like from the presenters’ perspective. This is one of the smaller ballrooms. My earlier sessions were in larger rooms, maybe 3 times this size. I took this picture about 15 minutes before the session started as people were beginning to drift in.

The amazing RootsTech techs had me wired up to microphones and had verified that the audio and video equipment was working correctly, so now it was just waiting.

My cousin, John Payne, who co-administers the Speaks surname project with me, came by and took this great picture of the two of us. We’ve made huge inroads connecting the various Speake(s) lines in America, plus finally proving our home village in England, thanks to the Big Y-700 test, followed by church records. All is takes, sometimes, is that one critical match.

As I sat there, waiting to begin the mitochondrial DNA session, I couldn’t help but reflect upon all of the women who came before me and how fortunate I was to have been in the right place at the right time to be a member of the Million Mito team.

These are my direct matrilineal ancestors who give me, and my daughter, pictured at left, their mitochondrial DNA. I felt them with me as I sat there, waiting.

The woman at furthest right, Barbara Drechsel (1848-1930), immigrated to Indiana from Germany as a child with her parents in the 1850s. Before her came thousands of generations of women with no photos, of course, and no names before Barbara Freiberger, another eight generations earlier, born about 1621 in Germany.

Before that, which was before church and other records, prior to the 30 Years War, this lineage came from Scandinavia where some of my exact matches are still found today.

Before beginning, I said a positive affirmation and thanked my ancestors – so very honored to introduce them. I know they were proud of me, a member of the team that opened the door to the distant past. I wouldn’t be here if not for every one of their lives.

In this session, I would discuss, for the first time ever, the new Mitotree and my/our connection to all of humanity some 7000 generations ago, more or less.

The mutations we carry over those generations form an unbroken chain of breadcrumbs, connecting us to mitochondrial Eve who lived about 145,000 years ago. We revealed that breakthrough finding in the Haplogroup L7 paper, published in 2022.

I’m still in absolute awe that we have been able to both reach that far back in time AND, at the same time, make the newest haplogroups and haplotype clusters genealogically relevant. I will write more about that soon, but for now, I wrote about the Mitotree release here and you can find articles by Katy Rowe-Schurwanz here and here.

I’m very excited about my new mitochondrial DNA results for my ancestral lines that I track and have already made headway on several.

I’m not the only one.

Not only was I excited about my results, many other people have had breakthroughs too, including Mark Thompson, one of our genealogy AI experts who also spoke at RootsTech. I particularly love his AI generated image.

If you haven’t yet, check your mitochondrial DNA results.

It’s a Wrap

Another year done, another RootsTech under our belts. Hopefully everyone is over the “conference crud” by now and are busily applying their newfound knowledge.

You can view either live-cast sessions or RootsTech webinars, here.

I saw a meme posted sometime during the conference that coined the term “exhausterwhelmulated,” a combination of exhausted, overwhelmed and overstimulated at the same time.

I added exhilarated and elated to the mix and asked ChatGPT to draw me a picture of someone at a genealogy conference feeling those simultaneous emotions.

ChatGPT titled this request “Genealogy Conference Overload,” which made me laugh.

The first two attempts looked like the person had a headache, which I fully understood, so I asked ChatGPT to make the person look happy to be there.

This person, carrying a coffee like I often do, looks like they have just discovered the great irony that they have chased the wrong ancestor for some 20 years – with “laugh or I’ll cry” mania being their overwhelm “go to” in that minute.

This one made me laugh too!

Yes, indeed, I think every single one of us, especially at RootsTech, has experienced this exact adrenaline-fueled emotion.

We leave with a VERY long to-do list, exhausted but full of anticipation and buoyed by excitement. Filled with so much gratitude for our cousins and fellow genealogists, the speakers, vendors, DNA to solve thorny problems, new tools and records, FamilySearch who sponsors RootsTech itself and their amazing employees, plus the legions of the volunteers who make it all work.

Thank you! Thank you! Thank you!

FamilyTreeDNA’s New Matrix Shows How Your Matches Are Related to Each Other

Click on any image to enlarge

FamilyTreeDNA’s new reworked Matrix includes relationships, in other words, how your matches are related to each other. But there’s more. It also includes the number of shared segments and the number of cMs shared between your matches.

You can then push those matches through to the chromosome browser to see exactly which segments overlap between you and your matches.

This is a game-changer!!

Why Are These Features Important?

For genealogists, knowing how your matches are related to each other, or not, is a HUGE clue about your common ancestor. Clusters of people who match each other are an important road sign directing you to a specific ancestor who contributed the same DNA segment or segments to all of you.

FamilyTreeDNA just released several VERY cool updates for their Matrix comparison tool. Plus, you get to select a group of 10 people to compare.

The purpose of the Matrix tool is to select Family Finder autosomal matches who are then displayed in a grid matrix for comparison, showing if and how those matches match each other.

Specifically:

  • Do your matches match each other?
  • What is their estimated relationship to each other?
  • How many segments of DNA do they share with each other?
  • How many cMs (centiMorgans) of DNA do they share with each other?

You can then push 7 matches through to the chromosome browser to see if they match on any of the same segments.

Automated Triangulation

If you are comparing bucketed (maternal or paternal) matches, or matches known to belong to the same side of your tree, the shared segments are automatically triangulated.

How cool is this?!!!

Keep in mind, though, that you may be related to someone through multiple ancestors, and they could be from both parent’s sides, so pay attention to the ancestral segment history.

Remember, every segment has its own unique history.

Let’s step through the new Matrix features and see how they work.

Select the Matrix

Navigate to the Matrix tool under “See More” under Autosomal DNA Results and Tools.

Under “Select Matches” you can select “All Matches” to choose from all of your matches, or you can select a grouping of matches to be displayed in the menu, below.

These groupings are shortcuts for you so you don’t have to pick everyone individually. You can also search for a name.

Click on the individuals you want to compare in the Matrix. The people you’ve selected from the group, at left, will appear in the box, at right. That’s who will be compared to each other.

Next, select which type of data will be compared.

I’m selecting “Close Relatives” for this example and “Relationship range.” First, I added my mother so I could see who matches with her.

Then I added the rest of the people I want to compare. In this case, I’ve added my closest matches, even though they are from both sides of my tree.

Relationship Range

I’ve selected “Relationship range,” which will show me how my matches estimated relationships to each other.

Based on the identity of these matches, and how they match each other, I can now determine their ancestral connection.

If I didn’t know who was related maternally and paternally, this grid would remove all doubt became I’m comparing to one of my parents.

If you don’t have a parent, adding close, known relatives on one or both sides will help immensely.

Be sure to make notes about what you’ve discovered on your matches page, and paint to DNAPainter if that’s how you’re tracking your segments to ancestors.

Number of Segments Shared

Now, I’ve selected “Number of segments shared” to compare the same group of people.

You can see the number of shared segments between Mom’s matches. Donald and Cheryl are full siblings.

The display shows how these people match Mom, and each other.

Melissa is Mom’s paternal second cousin. I was able to piece this together with the help of how she matches Mom and Mom’s known paternal first cousins, Cheryl and Donald.

Total cMs Shared

Next, I’m selecting “Total cMs shared” for comparison.

Looking at the number of shared cMs, even if I didn’t know that Donald and Cheryl were full siblings, I would now.

You can also push these through to the chromosome browser. I’ll illustrate in a minute.

Bucketed or Parental Side Matching

My favorite groupings for the new Matrix are the bucketed, meaning parental or maternal “side” matching.”

When your matches are already bucketed, thanks to having linked known matches to their profile card in your tree, the system does a lot of the “side” work for you behind the scenes.

When you select “Maternal, “Paternal” or “Paternal and Maternal” matches, the people who have been bucket to either side, or those related to you on both sides, are listed in the selection box.

I’m selecting 7 of my maternal bucketed matches because I’m going to push them through to the chromosome browser for additional evaluation. I’m not including my mother because I already know these people are related to both me and her, because they are bucketed maternally.

They’re compared in the various matrix configurations.

From the Shared cM comparison table, I can easily click to display matches in the chromosome browser.

If you’re comparing more than 7 people, you’ll need to reduce it to 7. I excluded my Mom because I already know she matches all of them.

Click on the Compare Chromosome Browser at the bottom for the 7 people selected.

I know that cousin Charles descends from Mom’s paternal Lentz line, and has no other connection, so I know that these other cousins who also match me on that same segment are also from Mom’s Lentz line.

I can also tell that the shared segments on chromosome 1 are from Mom’s maternal Lore line.

Shown here are the common ancestors in Mom’s pedigree chart. They are 4 and 5 generations back in time for me.

Look how easy that was!

I love this new Matrix tool.

Triangulation

Because three or more people, including me, match on the same segments, this means they also triangulate.

In the example above, we have two distinct triangulation groups. I’m only showing chromosomes 1-3 for illustration purposes, but there are also more triangulation groups on the other chromosomes. If I add other people, new triangulation groups will form!

Of course, these are my maternal bucketed matches, so I’m safe to reach that conclusion. If my father’s matches were also loaded here, I would have to check the matrix and see if these people also matched each other before I could determine that they triangulate.

Check Your Matches and Upload

Be sure to upload any tests to FamilyTreeDNA that you manage at other vendors, and encourage your cousins to upload too.

This combination of features is unique to FamilyTreeDNA. The more relatives you have available to match, especially when you already know the common ancestor, the better. Be sure to link your matches to their placard in your tree so that FamilyTreeDNA can do the bucketing for you.

Even if you don’t link people, you can still benefit greatly from the new matrix tool by just having your DNA available for matching. The matrix will help you sort out matches and identify who is related to whom, and how.

Take a look! What are you discovering?

Six Ways to Figure Out How We’re Related

In my latest Webinar, Six Ways to Figure Out How We’re Related, I discuss the various tools from Ancestry, FamilyTreeDNA, MyHeritage, and 23andMe – plus clusters from Genetic Affairs and the amazing DNAPainter.

This webinar lives in the Legacy Family Tree Webinar library, but as part of the “webtember” lineup, you can view it for free through the end of September.

It’s always exciting to discover a new match at one of the DNA testing companies, which, of course, begs the question of how you’re related.

So, what are the six ways to figure out how you’re related, and how do you use them?

Come along for a step-by-step guide!

Shared Matches

We begin with how each vendor handles shared matches, what that feature is called, where to find the information, and how to interpret what they are telling you.

23andMe goes a step further and creates a genetic tree, of sorts, although that functionality has changed since their breach last October.

Bucketing and Sides

Two vendors go a step further and provide unique tools to divide your matches maternally and paternally.

FamilyTreeDNA buckets your matches maternally and paternally (or both) based on matches you link to their profile cards in your tree. FamilyTreeDNA then uses your linked matches to triangulate with other matches and assign your matches accordingly, providing a maternal and paternal match list. Bucketing, also known as Family Matching, is one of my favorite tools.

Note that linking matches at FamilyTreeDNA requires that you have transferred your tree to MyHeritage. I wrote about that and provided instructions here and here, and produced a complimentary webinar, too.

Ancestry also divides your matches by parent, but they use a different technique based on their Sideview technology and either ethnicity or shared matches.

Surnames and Locations

Surnames and locations, either separately or together, provide HUGE hints!

MyHeritage provides a nice summary for each of your matches that includes ancestral surnames, a map of locations in common, and “Smart Matches” which shows you people in common in both of your trees. There are several ways to use these tools.

FamilyTreeDNA also provides a list of surnames. You can view either the surnames in common with a match, or all of their ancestral surnames, with locations if provided. The tester enters these surnames, and we review how to complete that step.

Ancestry also provides shared surnames, with clickable links to the number of people in your matches tree with that surname, plus common locations.

X-DNA

X-DNA is probably the most underutilized DNA matching tool. While each of the vendors actually test the X chromosome, only one, FamilyTreeDNA, provides X-matching. You can obtain X-matching results by uploading your DNA file to FamilyTreeDNA. I’ve provided upload/download instructions for all companies, here.

X-DNA has a very unique inheritance pattern because males only inherit an X chromosome from their mother which limits the number of potential common ancestors for any two testers. In other words, X-DNA matching does half your work for you!

Clustering Technology – AutoClusters, the Matrix and DNAPainter

In the past few years, match clustering has become a very useful tool. Clustering shows which of your matches match you and each other.

Genetic Affairs offers several flavors of these clusters, and both MyHeritage and GEDmatch have incorporated Genetic Affairs clusters into their product offerings.

If you haven’t used AutoClusters yet, by all means, try them out.

FamilyTreeDNA offers the Matrix, a slightly different version of clustering. You can select 10 people from your match list to see if they also match each other. Shared matches don’t automatically mean triangulation between you and those two people, or even that all three people descend from the same line. However, if the people are bucketed to your same side (parent) and they share common segments with you in the chromosome browser, they triangulate.

You’ll want to paint those matches to DNAPainter to determine which ancestor you share, especially if they haven’t provided a tree.

DNAPainter provides your chromosomes as the “canvas” upon which to paint your matches in order to correlate segments with ancestors and identify common ancestral lines with mystery matches.

Three vendors, FamilyTreeDNA, MyHeritage, and GEDmatch provide segment information with matches for you to paint. I illustrate how I walk segments back in time, identifying our most distant common ancestor possible.

Theories of Family Relativity and ThruLines

Both MyHeritage and Ancestry provide a combination of DNA matching and tree triangulation, where they search the trees of your DNA matches to find common ancestors with you – although their implementation is different.

MyHeritage’s Theories of Family Relativity provides varying theories about common ancestors for you and a specific match using both trees and historical documents. You can review the various pathways and confirm or reject theories. I love this tool.

Ancestry’s Thrulines functions a bit differently, showing you all of your matches that descend from a common ancestor in all your matches’ trees. Sometimes, the trees are incorrect, but Theories of Family Relativity and ThruLines should still be used as hints.

I showed how ThruLines helped me discover what happened to one of my ancestor’s grandchildren who was lost to the family at his mother’s death – and to all of us since. Not anymore.

Bonus – Y-DNA and Mitochondrial DNA at FamilyTreeDNA

Only FamilyTreeDNA offers both Y-DNA and Mitochondrial DNA testing and matching. All of the tools above pertain to autosomal DNA testing, which is named Family Finder at FamilyTreeDNA. Illustrated by the green arrow below, autosomal DNA testing measures and compares the DNA you inherited from each ancestral line, but that’s not the only game in town.

Y-DNA, in blue, for males, tracks the direct paternal line, which is the surname line in Western cultures. Mitochondrial DNA, in red, is passed from mothers to all of their children. Therefore, everyone can test, revealing matches and information about their mother’s direct matrilineal lineage.

Y-DNA testing includes the amazing Discover tool with a baker’s dozen different reports, including ancient DNA. Mitochondrial DNA will soon have its own MitoDiscover after the rollout of the new Mitotree.

Both tests include “Matches Maps” to help you determine how you are related to your matches, as well as where your ancestors came from before the advent of surnames.

The Advanced Matching feature allows you to select multiple tests to see if your matches match you on combined types of tests.

Tune In

Now that you know what we cover in the webinar, please tune in to see how to use these awesome tools. Be sure to fish in all four “ponds” plus GEDmatch, where you may find people who didn’t test at a company that provides a chromosome browser or matching segment information.

Tools provided by the DNA testing vendors facilitate multiple ways to determine how we match and which ancestor(s) we have in common.

You can watch the webinar, here.

Additionally, subscribers to Legacy Family Tree Webinars have access to the 25-page syllabus with even more information!

A Legacy Family Tree Webinar subscription normally costs $49.95 per year, but through the end of September, there’s a coupon code good for 20% off. Just click here, then enter webtember24 at the checkout.

Which DNA Test Should I Buy? And Why?

Which DNA test should I buy, and why?

I receive questions like this often. As a reminder, I don’t take private clients anymore, which means I don’t provide this type of individual consulting or advice. However, I’m doing the next best thing! In this article, I’m sharing the step-by-step process that I utilize to evaluate these questions so you can use the process too.

It’s important to know what questions to ask and how to evaluate each situation to arrive at the best answer for each person.

Here’s the question I received from someone I’ll call John. I’ve modified the wording slightly and changed the names for privacy.

I’m a male, and my mother was born in Charleston, SC. My maternal grandmother’s maiden name was Jones and a paternal surname was Davis. The family was supposed to have been Black, Dutch, Pennsylvania Dutch, and Scots-Irish…only once was I told I was 3/16 Indian, with Davis being 3/4 and Jones being full Indian.

Do I have enough reasonable information to buy a test, and which one?

Please note that it’s common for questions to arrive without all the information you need to provide a sound answer – so it’s up to you to ask those questions and obtain clarification.

Multiple Questions

There are actually multiple questions here, so let me parse this a bit.

  1. John never mentioned what his testing goal was.
  2. He also never exactly said how the paternal line of Davis was connected, so I’ve made an assumption. For educational purposes, it doesn’t matter because we’re going to walk through the evaluation process, which is the same regardless.
  3. John did not include a tree or a link to a tree, so I created a rudimentary tree to sort through this. I need the visuals and normally just sketch it out on paper quickly.
  4. Does John have enough information to purchase a test?
  5. If so, which test?

There is no “one size fits all” answer, so let’s discuss these one by one.

Easy Answers First

The answer to #4 is easy.

Anyone with any amount of information can purchase a DNA test. Adoptees do it all the time, and they have no prior information.

So, yes, John can purchase a test.

The more difficult question is which test, because that answer depends on John’s goals and whether he’s just looking for some quick information or really wants to delve into genealogy and learn. Neither approach is wrong.

Many people think they want a quick answer –  and then quickly figure out that they really want to know much more about their ancestors.

I wrote an article titled DNA Results – First Glances at Ethnicity and Matching for new testers, here.

Goals

Based on what John said, I’m going to presume his goals are probably:

  • To prove or disprove the family oral history of Black, Dutch, Pennsylvania Dutch (which is actually German,) Scots-Irish, and potentially Native American.
  • John didn’t mention actual genealogy, which would include DNA matches and trees, so we will count that as something John is interested in secondarily. However, he may need genealogy records to reach his primary goal.

If you’re thinking, “The process of answering this seemingly easy question is more complex than I thought,” you’d be right.

Ethnicity in General

It sounds like John is interested in ethnicity testing. Lots of people think that “the answer” will be found there – and sometimes they are right. Often not so much. It depends.

The great news is that John really doesn’t need any information at all to take an autosomal DNA test, and it doesn’t matter if the test-taker is male or female.

To calculate each tester’s ethnicity, every testing company compiles their own reference populations, and John will receive different results at each of the major companies. Each company updates their ethnicity results from time to time as well, and they will change.

Additionally, each company provides different tools for their customers.

The ethnicity results at different companies generally won’t match each other exactly, and sometimes the populations look quite different.

Normally, DNA from a specific ancestor can be found for at least 5 or 6 generations. Of course, that means their DNA, along with the DNA from all of your other ancestors is essentially combined in a communal genetic “pot” of your chromosomes, and the DNA testing company needs to sort it out and analyze your DNA for ethnicity.

DNA descended from ancestors, and their populations, further back in people’s trees may not be discerned at all using autosomal DNA tests.

A much more specific “ethnicity” can be obtained for both the Y-DNA line, which is a direct patrilineal line for men (blue arrow,) and the mitochondrial DNA line (pink arrows,) which is a direct matrilineal line for everyone, using those specific tests.

We will discuss both of those tests after we talk about the autosomal tests available from the four major genealogy DNA testing companies. All of these tools can and should be used together.

Let’s Start with Native American

Let’s evaluate the information that John provided.

John was told that he “was 3/16 Indian, with Davis being 3/4 and Jones being full Indian.”

We need to evaluate this part of his question slightly differently.

I discussed this in the article, Ancestral DNA Percentages – How Much of Them is in You?

First, we need to convert generations to 16ths.

You have two ancestors in your parent’s generation, four in your grandparents, and so forth. You have 16 great-great-grandparents. So, if John was 3/16th Native, then three of his great-great-grandparents would have been fully Native, or an equivalent percentage. In other words, six ancestors in that generation could have been half-Native. Based on what John said, they would have come from his mother’s side of the tree. John is fortunate to have that much information to work with.

He told us enough about his tree that we can evaluate the statement that he might be 3/16ths Native.

Here’s the tree I quickly assembled in a spreadsheet based on John’s information.

His father, at left, is not part of the equation based on the information John provided.

On his mother’s side, John said that Grandfather Davis is supposed to be three-quarters Native, which translates to 12/16ths. Please note that it would be extremely beneficial to find a Y-DNA tester from his Davis line, like one of his mother’s brothers, for example.

John said that his Grandmother Jones is supposed to be 100% Native, so 16/16ths.

Added together, those sum to 28/32, which reduces down to 14/16th or 7/8th for John’s mother.

John would have received half of his autosomal DNA from his mother and half from his non-Native father. That means that if John’s father is 100% non-Native, John would be half of 14/16ths or 7/16ths, so just shy of half Native.

Of course, we know that we don’t always receive exactly 50% of each of our ancestors’ DNA (except for our parents,) but we would expect to see something in the ballpark of 40-45% Native for John if his grandmother was 100% Native and his grandfather was 75%.

Using simple logic here, for John’s grandmother to be 100% Native, she would almost assuredly have been a registered tribal member, and the same if his grandfather was 75% Native. I would think that information would be readily available and well-known to the family – so I doubt that this percentage is accurate. It would be easy to check, though, on various census records during their lifetimes where they would likely have been recorded as “Indian.” They might have been in the special “Indian Census” taken and might be living on a reservation.

It should also be relatively easy to find their parents since all family members were listed every ten years in the US beginning with the 1850 census.

The simple answer is that if John’s grandparents had as much Native as reported, he would be more than 3/16th – so both of these factoids cannot simultaneously be accurate. But that does NOT mean neither is accurate.

John could be 7/8th or 40ish%, 3/16th or 18ish%, or some other percentage. Sometimes, where there is smoke, there is fire. And that seems to be the quandary John is seeking to resolve.

Would  Ethnicity/Population Tests Show This Much Native?

Any of the four major testing companies would show Native for someone whose percentage would be in the 40% or 18% ballpark.

The easiest ethnicities to tell apart from one another are continental-level populations. John also stated that he thinks he may also have Black ancestry, plus Dutch, Pennsylvania Dutch (German), and Scots-Irish. It’s certainly possible to verify that using genealogy, but what can DNA testing alone tell us?

How far back can we expect to find ethnicities descending from particular ancestors?

In this table, you can see at each generation how many ancestors you have in that generation, plus the percentage of DNA, on average, you would inherit from each ancestor.

All of the major DNA testing companies can potentially pick up small trace percentages, but they don’t always. Sometimes one company does, and another doesn’t. So, if John has one sixth-generation Native American ancestor, he would carry about 1.56% Native DNA, if any.

  • Sometimes a specific ethnicity is not found because, thanks to random recombination, you didn’t inherit any of that DNA from those ancestors. This is why testing your parents, grandparents, aunts, uncles, and siblings can be very important. They share your same ancestors and may have inherited DNA that you didn’t that’s very relevant to your search.
  • Sometimes it’s not found because the reference populations and algorithms at that testing company aren’t able to detect that population or identify it accurately, especially at trace levels. Every DNA testing company establishes their own reference populations and writes internal, proprietary ethnicity analysis algorithms.
  • Sometimes it’s not found because your ancestor wasn’t Native or from that specific population.
  • Sometimes it’s there, but your population is called something you don’t expect.

For example, you may find Scandinavian when your ancestor was from England or Ireland. The Vikings raided the British Isles, so while some small amount of Scandinavian is not what you expect, that doesn’t mean it‘s wrong. However, if all of your family is from England, it’s not reasonable to have entirely Scandinavian ethnicity results.

It’s also less likely as each generation passes by that the information about their origins gets handed down accurately to following generations. Most non-genealogists don’t know the names of their great-grandparents, let alone where their ancestors were from.

Using a 25-year average generation length, by the 4th generation, shown in the chart above, you have 16 ancestors who lived approximately 100 years before your parents were born, so someplace in the mid-1800s. It’s unlikely for oral history from that time to survive intact. It’s even less likely from a century years earlier, where in the 7th generation, you have 128 total ancestors.

The best way to validate the accuracy of your ethnicity estimates is by researching your genealogy. Of course, you need to take an ethnicity test, or two, in order to have results to validate.

Ethnicity has a lot more to offer than just percentages.

Best Autosomal Tests for Native Ethnicity

Based on my experience with people who have confirmed Native ancestry, the two best tests to detect Native American ethnicity, especially in smaller percentages, are both FamilyTreeDNA and 23andMe.

Click images to enlarge

In addition to percentages, both 23andMe and FamilyTreeDNA provide chromosome painting for ethnicity, along with segment information in download files. In other words, they literally paint your ethnicity results on your chromosomes.

They then provide you with a file with the “addresses” of those ethnicities on your chromosomes, which means you can figure out which ancestors contributed those ethnicity segments.

The person in the example above, a tester at FamilyTreeDNA, is highly admixed with ancestors from European regions, African regions and Native people from South America.

Trace amounts of Native American with a majority of European heritage would appear more like this.

You can use this information to paint your chromosome segments at DNAPainter, along with your matching segments to other testers where you can identify your common ancestors. This is why providing trees is critically important – DNA plus ancestor identification with our matches is how we confirm our ancestry.

This combination allows you to identify which Native (or another ethnicity) segments descended from which ancestors. I was able to determine which ancestor provided that pink Native American segment on chromosome 1 on my mother’s side.

I’ve provided instructions for painting ethnicity segments to identify their origins in specific ancestors, here.

Autosomal and Genealogy

You may have noticed that we’ve now drifted into the genealogy realm of autosomal DNA testing. Ethnicity is nice, but if you want to know who those segments came from, you’ll need:

  • Autosomal test matching to other people
  • To identify your common ancestor with as many matches as you can
  • To match at a company who provides you with segment information for each match
  • To work with DNAPainter, which is very easy

The great news is that you can do all of that using the autosomal tests you took for ethnicity, except at Ancestry who does not provide segment information.

Best Autosomal Test for Matching Other Testers

The best autosomal test for matching may be different for everyone. Let’s look at some of the differentiators and considerations.

If you’re basing a testing recommendation solely on database size, which will probably correlate to more matches, then the DNA testing vendors fall into this order:

If you’re basing that recommendation on the BEST, generally meaning the closest matches for you, there’s no way of knowing ahead of time. At each of the four DNA testing companies, I have very good matches who have not tested elsewhere. If I weren’t in all four databases, I would have missed many valuable matches.

If you’re basing that recommendation on which vendor began testing earliest, meaning they have many tests from people who are now deceased, so you won’t find their autosomal tests in other databases that don’t accept uploads, the recommended testing company order would be:

If you’re basing that recommendation on matches to people who live in other countries, the order would be:

Ancestry and 23andMe are very distant third/fourth because they did not sell widely outside the US initially and still don’t sell in as many countries as the others, meaning their testers’ geography is more limited. However, Ancestry is also prevalent in the UK.

If you’re basing that recommendation on segment information and advanced tools that allow you to triangulate and confirm your genetic link to specific ancestors, the order would be:

Ancestry does NOT provide any segment information.

If you’re basing that recommendation on unique tools provided by each vendor, every vendor has something very beneficial that the others don’t.

In other words, there’s really no clear-cut answer for which single autosomal DNA test to order. The real answer is to be sure you’re fishing in all the ponds. The fish are not the same. Unique people test at each of those companies daily who will never be found in the other databases.

Test at or upload your DNA to all four DNA testing companies, plus GEDmatch. Step-by-step instructions for downloading your raw data file and uploading it to the DNA testing companies who accept uploads can be found, here.

Test or Upload

Not all testing companies accept uploads of raw autosomal DNA data files from other companies. The good news is that some do, and it’s free to upload and receive matches.

Two major DNA testing companies DO NOT accept uploads from other companies. In other words, you have to test at that company:

Two testing companies DO accept uploads from the other three companies. Uploads and matching are free, and advanced features can be unlocked very cost effectively.

  • FamilyTreeDNA – free matching and $19 unlock for advanced features
  • MyHeritage – free matching and $29 unlock.for advanced features

I recommend testing at both 23andMe and Ancestry and uploading one of those files to both FamilyTreeDNA and MyHeritage, then purchasing the respective unlocks.

GEDmatch

GEDmatch is a third-party matching site, not a DNA testing company. Consider uploading to GEDmatch because you may find matches from Ancestry who have uploaded to GEDmatch, giving you access to matching segment information.

Other Types of DNA

John provided additional information that may prove to be VERY useful. Both Y-DNA and mitochondrial DNA can be tested as well and may prove to be more useful than autosomal to positively identify the origins of those two specific lines.

Let’s assume that John takes an autosomal test and discovers that indeed, the 3/16th Native estimate was close. 3/16th equates to about 18% Native which would mean that three of his 16 great-great-grandparents were Native.

John told us that his Grandmother Jones was supposed to be 100% Native.

At the great-great-grandparent level, John has 16 ancestors, so eight on his mother’s side, four from maternal grandmother Jones and four from his maternal grandfather Davis.

John carries the mitochondrial DNA of his mother (red boxes and arrows,) and her mother, through a direct line of females back in time. John also carries the Y-DNA of his father (dark blue box, at left above, and blue arrows below.)

Unlike autosomal DNA which is admixed in every generation, mitochondrial DNA (red arrows) is inherited from that direct matrilineal line ONLY and never combines with the DNA of the father. Mothers give their mitochondrial DNA to both sexes of their children, but men never contribute their mitochondrial DNA to offspring. Everyone has their mother’s mitochondrial DNA.

Because it never recombines with DNA from the father, so is never “watered down,” we can “see” much further back in time, even though we can’t yet identify those ancestors.

However, more importantly, in this situation, John can test his own mitochondrial DNA that he inherited from his mother, who inherited it from her mother, to view her direct matrilineal line.

John’s mitochondrial DNA haplogroup that will be assigned during testing tells us unquestionably whether or not his direct matrilineal ancestor was Native on her mother’s line, or not. If not, it may well tell us where that specific line originated.

You can view the countries around the world where Y-DNA haplogroups are found, here, and mitochondrial haplogroups, here.

If John’s mitochondrial DNA haplogroup is Native, that confirms that one specific line is Native. If he can find other testers in his various lines to test either their Y-DNA or mitochondrial DNA, John can determine if other ancestors were Native too. If not, those tests will reveal the origins of that line, separate from the rest of his genealogical lines.

Although John didn’t mention his father’s line, if he takes a Y-DNA test, especially at the Big Y-700 level, that will also reveal the origins of his direct paternal line. Y-DNA doesn’t combine with the other parent’s DNA either, so it reaches far back in time too.

Y-DNA and mitochondrial DNA tests are laser-focused on one line each, and only one line. You don’t have to try to sort it out of the ethnicity “pot,” wondering which ancestor was or was not Native.

My Recommendation

When putting together a testing strategy, I recommend taking advantage of free uploads and inexpensive unlocks when possible.

  • To confirm Native American ancestry via ethnicity testing, I recommend testing at 23andMe and uploading to FamilyTreeDNA, then purchasing the $19 unlock. The free upload and $19 unlock are less expensive than testing there directly.
  • For matching, I recommend testing at Ancestry and uploading to MyHeritage, then unlocking the MyHeritage advanced features for $29, which is less expensive than retesting. Ancestry does not provide segment information, but MyHeritage (and the others) do.

At this point, John will have taken two DNA tests, but is now in all four databases, plus GEDmatch if he uploads there.

  • For genealogy research on John’s lines to determine whether or not his mother’s lines were Native, I recommend an Ancestry and a MyHeritage records subscription, plus using WikiTree, which is free.
  • To determine if John’s mother’s direct matrilineal female line was Native, I recommend that John order the mitochondrial DNA test at FamilyTreeDNA.
  • When ordering multiple tests, or uploading at FamilyTreeDNA, be sure to upload/order all of one person’s tests on the same DNA kit so that those results can be used in combination with each other.

Both males and females can take autosomal and mitochondrial DNA tests.

  • To discover what he doesn’t know about his direct paternal, meaning John’s surname line – I recommend the Big Y-700 test at FamilyTreeDNA.

Only males can take a Y-DNA test, so women would need to ask their father, brother, or paternal uncle, for example, to test their direct paternal line.

  • If John can find a male Davis from his mother’s line, I recommend that he purchase the Big Y-700 test at FamilyTreeDNA for that person, or check to see if someone from his Davis line may have already tested by viewing the Davis DNA Project. Like with mitochondrial DNA, the Y-DNA haplogroup will tell John the origins of his direct Davis male ancestor – plus matching of course. He will be able to determine if they were Native, and if not, discover the origins of the Davis line.
  • For assigning segments to ancestors and triangulating to confirm descent from a common ancestor, I recommend 23andMe, MyHeritage, FamilyTreeDNA and GEDmatch, paired with DNAPainter as a tool.

Shopping and Research List

Here are the tests and links recommended above:

More Than He Asked

I realize this answer is way more than John expected or even knew to ask. That’s because there is often no “one” or “one best” answer. There are many ways to approach the question after the goal is defined, and the first “answer” received may be a bit out of context.

For example, let’s say John has 2% Native ancestry and took a test at a vendor who didn’t detect it. John would believe he had none. But a different vendor might find that 2%. If it’s on his mother’s direct matrilineal line, mitochondrial DNA testing will confirm, or refute Native, beyond any doubt, regardless of autosomal ethnicity results – but only for that specific ancestral line.

Autosomal DNA can suggest Native across all your DNA, but Y-DNA and mitochondrial DNA confirm it for each individual ancestor.

Even when autosomal testing does NOT show Native American, or African, for example, it’s certainly possible that it’s just too far back in time or has not been passed down during random recombination, but either Y-DNA or mitochondrial DNA will unquestionably confirm (or refute) the ancestry in question if the right person is tested.

This is exactly why I attempt to find a cousin who descends appropriately from every ancestor and provide testing scholarships. It’s important to obtain Y-DNA and mitochondrial DNA information for each ancestor.

Which Test Should I Order?

What steps will help you decide which test or tests to take?

  1. Define your testing goal.
  2. Determine if your Y-DNA or mitochondrial DNA will help answer the question.
  3. Determine if you need to find ancestors another generation or two back in time to get the most benefit from DNA testing. In our example, if John discovered that both of his grandparents were enrolled tribal members, that’s huge, and the tribe might have additional information about his family.
  4. Subscribe to Ancestry and MyHeritage records collections as appropriate to perform genealogical research. Additional information not only provides context for your family, it also provides you with the ability to confirm or better understand your ethnicity results.
  5. Extend your tree so that you can obtain the best results from the three vendors who support trees; Ancestry, FamilyTreeDNA, and MyHeritage. All three use trees combined with DNA tests to provide you with additional information.
  6. Order 23andMe and Ancestry autosomal DNA tests.
  7. Either test at or upload one of those tests to MyHeritage, FamilyTreeDNA, and GEDmatch.
  8. If a male, order the Big Y-700 DNA test. Or, find a male from your ancestral line who has taken or will take that test. I always offer a testing scholarship and, of course, share the exciting results!
  9. Order a mitochondrial DNA test for yourself and for appropriately descended family members to represent other ancestors. Remember that your father (and his siblings) all carry your paternal grandmother’s mitochondrial DNA. That’s often a good place to start after testing your own DNA.
  10. If your parents or grandparents are alive, or aunts and uncles, test their autosomal DNA too. They are (at least) one generation closer to your ancestors than you are and will carry more of your ancestors’ DNA.
  11. Your siblings will carry some of your ancestors’ DNA that you do not, so test them too if both of your parents aren’t available for testing.

Enjoy!!!

Chromosomes and Genealogy

Sometimes people ask about how chromosomes relate to genealogy. Every single one of us started with that question, right?

Are chromosomes different sizes, and does that matter? What are the mystery terms, cMs and SNPs? How does all of this intersect with genealogy? Do I care?

These are all great questions, and of course, there are different ways to answer. Let’s start with some basics.

Chromosomes 1-22

First, you have two copies of each of chromosomes 1-22.

The karyogram above, a photo taken through a microscope, courtesy of the National Human Genome Research Institute, shows the chromosomes of a human male. I’ve added the numbering and labeled the X and Y chromosomes (23).

You inherit one copy of each chromosome from each of your parents. You can see the two halves of each chromosome, above. One half of each chromosome is contributed by the person’s mother, and the other half is contributed by the father.

That’s why DNA matching works, and each match can be designated as “maternal” or “paternal,” depending on how your match is related to you.

Each match will be related either maternally, paternally, or sometimes, both. Of course, that’s presuming the matches are identical by descent, and not identical by chance, but that’s a different discussion. For this article, we’re referencing valid matches with whom you share common ancestors – whether you know who they are or not.

Your 23rd chromosome is different than chromosomes 1-22.

Chromosome 23 Determines a Child’s Sex

Your 23rd chromosome is your sex-determination chromosome and is inherited differently.

You still inherit one copy of chromosome 23 from each parent.

  • Males inherit a Y chromosome from their father, which is what makes males male.
  • Males inherit an X chromosome from their mother.
  • Females inherit an X chromosome from both parents, which makes them female.
Chromosome 23 Father Contributes Mother Contributes
Male Child Y chromosome X chromosome
Female Child X chromosome X chromosome

Because males don’t inherit an X chromosome from their father, X chromosome matching for genealogy has a unique and specific pattern of descent which allows testers to immediately eliminate some potential common ancestors.

The Y chromosome can be tested separately for males and follows the direct paternal line. You can read about the 4 Kinds of DNA for Genetic Genealogy, here.

The X chromosome is quite useful for genealogy due to its unique inheritance path and is included by both FamilyTreeDNA and 23andMe in matching.

Picture This

Three of the four major vendors, plus GEDmatch, provide a visual match depiction of your chromosomes using a chromosome browser:

Unfortunately, Ancestry does not provide a chromosome browser or segment location information.

Using your chromosomes as the canvas, matches to your father and mother are shown using the chromosome browser at FamilyTreeDNA, below.

You can see that a tester matches both parents on the entire covered region of all of their chromosomes. The beginning and the end tips of each chromosome sometimes aren’t covered, and neither are some other regions that are very SNP-location-poor. Omitted regions are shown by hashes. Regions that are light grey, but not hashed, are covered, but the match’s test didn’t produce results in that region.

This is why you may have a slightly different size match with one parent versus the other, especially if they both didn’t test at the same vendor at the same time.

The chromosome browser graphic visually answers the chromosome size question, but there’s more to this answer. It’s easy to see that there’s a significant difference in the physical chromosome size, but there’s more to the story.

SNPs – Chromosome Street Addresses

SNPs, known as Single Nucleotide Polymorphisms, are mutations recorded at specific addresses on chromosomes. Each chromosome holds a specific number of addresses that are read during sequencing and used for match comparison.

All of your other matches that are not parent-child and not your identical twin will match on some subset of these locations.

The Rest of the Answer – Centimorgans and SNPs

Centimorgans (cMs) are units of recombination used to measure genetic distance. You can read a scientific definition here.

For our conceptual purposes, think of centimorgans as lines on a football field. They represent distance on the chromosome.

SNPs are locations that are compared between two people to see if a match occurs.

Think of SNPs as addresses for blades of grass on that football field where an expected value occurs. If values at that address are different, then they don’t match. If values are the same, then they do match. For autosomal DNA matching, we look for long runs of SNPs that match between two people to confirm a common ancestor.

Think of SNPs as blades of grass growing between the lines on the football field. In some areas, especially in my yard, there will be many fewer blades of grass between those lines than there would be on either a well-maintained football field, or maybe a manicured golf course. You can think of the lighter green bands as sparse growth and the darker green bands as dense growth.

If the distance between 2 lines on the football field is 8 cM, for example, and there are 700 blades of grass growing there, you’ll be a match to another person if (almost) all of your blades of grass between those 2 lines match, assuming the match threshold is minimally 8 cM and 700 SNPs.

For purposes of autosomal DNA, the combination of centimorgans (distance,) and the number of SNPs (locations) within that distance measurement determines if someone is considered a match to you. In other words, you’re listed as a match if the shared DNA is over the minimum or selected thresholds. Think of track and field hurdles. To get to the end (a match), you have to get over all of the hurdles!

For example, a threshold of 8 cM and 700 SNPs means that anyone who matches you equal to or greater than both of these cumulative thresholds will be displayed as a match. Centimorgans and SNPs work in tandem to ensure valid matches.

A Second Yardstick

So, the second measure of chromosome size is the number of cMs from the beginning to the end of the chromosome, and the number of SNPs on that chromosome.

Different vendors, and different DNA testing chips cover slightly different regions. This is my match with my mother, which shows:

  • Total matching cMs on each chromosome
  • Total matching SNPs on each chromosome
  • SNP Density, which is a calculation (cM/SNPs) showing how “thick” the SNP grass is on each chromosome

The higher the matching number of cMs, especially in a row (longest segment,) the higher quality the match, and the closer the relationship.

Note that endogamous, or intermarried populations, may need separate interpretations. I discussed the signs of endogamy in this article.

Calculating Matches

Some vendors provide the ability to select your match cM and SNP thresholds, and others make those selections for you. Most vendors no longer display the number of matching SNPs, given that SNP-poor regions are, for the most part, automatically eliminated, although you can view them in your matching segment download file. In other words, the vendors simply take care of this for you. The accepted rule of thumb has always been that 500 (some said 700) or fewer SNPs was too small to be genealogically relevant, regardless of the cM match size.

Vendors include numerous and varying factors in determining match quality and potential relationships, including:

  • Total shared DNA, meaning total matching cM
  • Longest shared, meaning contiguously matching DNA block
  • X matching
  • Sex of tester (especially with respect to X matching)
  • Endogamy flags
  • Half versus fully identical DNA regions (to positively identify relationships such as half vs full siblings)
  • Triangulated segments
  • Family Matching (maternal and paternal bucketing) at FamilyTreeDNA
  • Tree matching

Not all vendors include all factors, and each vendor utilizes proprietary algorithms for features like triangulation.

The question isn’t chromosome size or even match size alone, but the quality of the match plus additive genealogical features like Theories of Family Relativity at MyHeritage to identify common and even previously unknown ancestors.

Be sure to test at the primary vendors or upload for free to MyHeritage, FamilyTreeDNA and GEDmatch to receive as many matches as possible. You just never know where that match you really need is hiding!

Enjoy!
