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.

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!

Mitotree is Born

Mitotree is born and I can hardly contain my excitement.

The Million Mito R&D team members, along with many others at FamilyTreeDNA, are proud to introduce the new Mitotree and mtDNA Discover, which were brought to life thanks to one pivotal entrepreneurial figure, Bennett Greenspan, whose support and vision set the ball in motion and made Mitotree possible.

Left to right, the Million Mito science team is:

  • Goran Runfeldt, Head of R&D at FamilyTreeDNA
  • Dr. Paul Maier, Senior Population Geneticist at FamilyTreeDNA
  • Roberta Estes, DNAexplain, scientist, blogger, author, genetic genealogist, and Genographic Affiliate Researcher
  • Dr. Miguel Vilar, Genetic Anthropologist, Lead Scientist with the Genographic Project, and Professor at the University of Maryland
  • Bennett Greenspan, President Emeritus of FamilyTreeDNA, and avid genealogist
  • John Detsikas, Front End Developer who is responsible for the user interface for both Y-DNA Discover and now mtDNA Discover

The Million Mito Project Inception

The Million Mito Project was launched at RootsTech 2020 and encouraged people to test their mitochondrial DNA, both for their genealogy and to help build the database. More than a million samples were candidates, but only high-quality, full sequence results were used. In the process of building the tree, additional samples were incorporated from other public sources for tree construction.

Drum Roll – The Mitotree

A beta version of the Mitotree is being released today, and boy, is this a big deal.

Before we discuss the rest of what’s coming, I need to mention that the Mitotree is now evergreen, meaning that the tree will be updated periodically, as will mtDNA Discover. This lifetime value is included with the cost of your test, so there’s nothing more to purchase.

Haplogroups will change from time to time, as the tree does, so don’t fall in love with yours, and definitely, no tattoos😊

I’m going to be speaking in terms of “we,” meaning the Million Mito team who built the Mitotree and mtDNA Discover, plus an amazing team of FamilyTreeDNA folks who were absolutely essential in getting this out the door and to you.

The Mitotree is new from the ground up, and yes, haplogroup naming consistency with PhyloTree has been maintained where possible.

One of the unanticipated challenges we encountered was that the 2016 PhyloTree had to be recreated, essentially reverse engineered, to determine the rules they used regarding mutations for haplogroup creation. In other words, which mutations were valid and reliable, which weren’t, determining their relative importance, and so forth.

After the existing 2016 tree was recreated, the next hurdle to overcome was that none of the existing phylogenetic software used in academia would scale from 24,000 samples and 5500 subclades to more than a quarter million samples and 40,000 haplogroups, so that software had to be designed and written by R&D team members.

More information about this process will be forthcoming shortly, and a paper will be published with our methodology, but for right now, let’s look at the user experience and what’s being released now.

Here’s what’s coming today and over the next few days.

The beta Mitotree includes:

  • Over 40,000 branches
  • Over 250,000 mtFull Sequences from FTDNA
  • Over 10,000 third-party full sequences from GenBank, 1000 Genomes, etc.
  • Over 1000 Ancient Connections
  • Over 100 Notable Connections

More is on the way.

The new Mitotree is the tree provided in several formats within mtDNA Discover. You can view the public version of the tree, here, or sign on to your FamilyTreeDNA account and click through from your dashboard to see more.

Today’s Releases

The Mitotree doesn’t exist in a vacuum, so several updates and new features will be rolling out today.

  • mtDNA Discover, which includes the new Mitotree
  • New customer haplogroups for those who have taken mtFull sequence tests
  • New mtDNA matches page

New Haplogroups

New haplogroups have been calculated for FamilyTreeDNA customers who have taken the full sequence test. Those who have taken only the HVR1 or HVR1/HVR2 tests are encouraged to upgrade to the full sequence test.

Not everyone will receive a new Mitotree haplogroup that is different from their classic haplogroup, but most people will. Your original haplogroup is displayed with the classic tag, and the new Mitotree haplogroup with the beta tag.

If your classic and Mitotree haplogroups are the same, it means that either you have no more private variants (mutations) available to form a new haplogroup, or no one else from your lineage has tested yet.

New mtDNA Matches Page

If you click on your mtDNA matches, you’ll notice that the page has been redesigned to look and function like the other FamilyTreeDNA match pages.

If you click to view your matches, you’ll be able to view both the “old” classic haplogroup, and your matches’ new Mitotree haplogroup, plus a new haplotype if they have one. We will talk about haplotypes in a minute.

The people you match are the same as before, but matches may be recalculated in the future.

If you click through to the new mtDNA Discover from your dashboard, you’ll be able to view the public portion of mtDNA Discover, plus the additional customized information provided to FamilyTreeDNA mtFull sequence customers.

mtDNA Discover

If you have taken a full sequence test, sign on to your account to view your new haplogroup, then click on the new mtDNA Discover icon on your dashboard.

If you haven’t taken the mtFull sequence test, but the partial HVR1 or HVR2 versions, you can still view mtDNA Discover on your dashboard, but without the mtFull customization.

Customization that occurs exclusively for FamilyTreeDNA mtFull sequence customers includes:

  • Most detailed placement of your branch on Mitotree
  • Haplotype clusters
  • Additional Ancient Connections
  • Additional Notable Connections
  • The Match Time Tree
  • Globetrekker (coming soon)
  • The Group Time Tree (coming soon)

mtDNA Discover is similar to Y-DNA Discover.

You’ll be able to view a dozen new reports about your haplogroup in addition to the tools provided on your dashboard.

The new Mitotree can be viewed in several formats, each with its unique benefit.

  1. Time Tree – a genetic tree that shows when each haplogroup was formed, plus a country flag for where present-day testers report as the location of their earliest known ancestor (EKA)
  2. Classic Tree – a more traditional view of a phylogenetic tree, including the number of testers on each branch, the variants, or mutations that define the haplogroup, the era and approximate date of formation, and other details about the tree topology
  3. Scientific Details Variants Tab – shows the variants that differ in each haplogroup as you reach back in time
  4. Ancestral Path for the selected haplogroup – outlines your path back to early humans, including Denisovans.
  5. Match Time Tree for you and your matches (must be signed in to your account and click on mtDNA Discover icon)
  6. Group Time Tree (coming soon) for those who have joined projects

Match Time Tree

The Match Time Tree is extremely useful because it overlays your matches, plus their earliest known ancestors (EKA), on a genetic Time Tree, by haplogroup and haplotype, so you can see how you may be related, and when.

You can also see your matches that have now fallen into neighboring haplogroups, which suggests that they probably aren’t as genealogically close as people in your haplogroup. However, that’s not always the case, because mutations can occur at any time.

Haplotype Clusters

A haplotype cluster is a new concept introduced specifically for genealogists with the new Mitotree. Haplotypes are identified by numbered “F” groups. Three are shown, below.

There may be groups of people within a haplogroup that have exactly the same mutations, or genetic signature, and no additional mutations. Still, they may not form a new haplogroup. There could be several reasons for not forming a new haplogroup, including known SNP locations where mutations occur that are known to be unstable, such as location  315, which tends to accumulate random insertions and is ignored because of its known instability.

When multiple people share an exactly identical signature, meaning all of the same mutations, they are shown within a haplotype “F” cluster to provide additional specificity to the tree.

The haplotype has been designed to provide additional granularity to the tree and genealogically relevant information. The haplotype “Fxxxxxx” numbers are randomly generated and have no special meaning.

A word of caution here. While the haplotype sequences are identical, it is still possible that another tester from outside the cluster could be a closer relative. For example, they could have accumulated a fast mutating SNP in the last few generations, which would give them a different signature.

Someone who is actually genealogically close to you may be in a different haplotype, or no haplotype at all because no one matches them exactly. For example, if your aunt or sister has a heteroplasmy, they are a close relative and will be in your haplogroup, but won’t be in your haplotype cluster because of the heteroplasmy. So don’t ignore matches who aren’t in your haplotype.

In the above example, under haplogroup V71b, there is one group of three people of unknown origin, meaning they didn’t enter any location for their earliest known ancestor, plus haplotype F9712482 – all of whom are identical matches to each other, but don’t form a new haplogroup.

Beneath V71b is haplogroup V71b1 with nine people, plus two haplotype clusters. F1965416 consists of two people, and F8189900 consists of 16 people.

You can also see haplotype clusters bracketed on any of the Time Trees in mtDNA Discover as well.

More to Come

There’s more information to come in the next few days and weeks, and at RootsTech. I’ll be writing articles when I get back.

For now, take a look to see if you have a new haplogroup. The new haplogroup rollout is being staggered, and you should receive an email when yours has been posted. But there’s no need to wait. Go ahead, sign in and check now, check out mtDNA Discover, and have fun.

Guaranteed, you’ll learn something new, and you may discover the key to a new ancestor!

Welcome to 2025! – Opportunities and New Genetic Genealogy Articles

It’s a new year with new opportunities. Lots of ancestors to find and others to confirm.

For me, the best part is actually learning about my ancestors’ lives. If you’re a subscriber, I’m sure you’ve already noticed that.

These adventures and misadventures are what inspire my blog articles. What works well, what doesn’t and how to use multiple tools to unveil more about our ancestors.

That’s what motivates me. I hope it motivates you, too.

New Articles in the Works

I’d like to share some of the articles and educational events I have planned for 2025, then ask what topics you’d like to see.

Articles on the drawing board include:

  • MyHeritage DNA File Download Instructions Update
  • Mitotree – when released
  • Mitochondrial Discover – when released
  • Genealogy Proof Series – The series continues with autosomal, Y-DNA, and mitochondrial DNA proof.
  • The Forest of the Trees – Lots of different kinds of trees for both Y and mitochondrial DNA at FamilyTreeDNA. How to use them, for what, and when. This will probably be written as a series.
  • New features and developments from vendors as they occur
  • Acadian Ancestors – I hope to complete my Acadian 52 Ancestors articles. For those who don’t know, “52 Ancestors” is a challenge to write about one ancestor each week for a year. You can sign up with Amy Johnson Crow here to learn more and receive weekly prompts. It’s fun and allows you to focus on one ancestor at a time, and the history that occurred in their lifetime.

Other Learning Opportunities

In addition to those articles, I’ll be at RootsTech in person presenting:

  • DNA Academy – the 2025 version, soup to nuts
  • DNA for Native American Genealogy
  • Reveal Your Maternal Ancestors and Their Stories Using Mitochondrial DNA
  • Guide to FamilyTreeDNA – Using Y-DNA, Mitochondrial DNA, Autosomal, X-DNA and Associated Tools

I’ll also participate in other educational events with Legacy Family Tree Webinars, WikiTree, the North Carolina Genealogy Society, and FamilyTreeDNA. I’ll provide more information about them later.

Finding Information

Remember, you can always use a keyword search on this blog to find any topic I’ve written about previously.

Also, Google’s AI has apparently trained itself using my blog articles, as have a couple of other AI tools. I know this because my blog comes up as a resource when I google questions. You can try that, too.

Your Turn – What Do You Want?

There are always new topics, new features, or different ways to explain things.

  • What would you like to see covered in 2025?
  • Are there any hot genetic genealogy topics that you’d love to learn more about?

Please make your suggestions in a comment on this article.

Here’s wishing you a wonderful 2025 with lots of ancestor discoveries.

Leave No Stone Unturned, No Ancestor Behind: 10 Easy Steps to Capture DNA Clues

There’s a lot, a whole lot that DNA testing can tell you. Not just your own tests, but the genetic information carried by your relatives that you do not.

Recently, I’ve been reviewing my brick walls, which led me to realize there are several ancestors who are missing their mitochondrial DNA and/or Y-DNA  results. I need these to learn more about my ancestors that can’t be revealed any other way – and to break down those pesky brick walls.

I’ve solved two mysteries recently, one thanks to a Big Y-700 test, and a second very unexpectedly thanks to mitochondrial DNA – both thanks to cousins who tested. These revelations were very encouraging, especially since there’s no way other than DNA for me to break through these brick walls. The mitochondrial test had been sitting there, waiting for what seemed like forever until just the right other person tested.

I am in the process of unlocking several brick-walled ancestors by providing testing scholarships to people who are appropriately descended from known ancestors in those lines.

Don’t leave information on the table. If I were to tell you there even MIGHT be a book available about your family, you’d overturn Heaven and Earth to find it – but you don’t need to do that. All you need to do is order DNA tests for cousins.

All cousins can provide useful autosomal DNA results, but you do need to find appropriate cousins for Y-DNA and mitochondrial DNA testing.

I’m sharing the steps for how I accomplish this! You’ll be amazed at what’s out there – and someone may already have tested!

Take Advantage of the Holidays

I’m sharing NOW because it’s the holidays and you’re likely to gather with people you don’t see any other time – and because the best sale of the year for both Y-DNA and mitochondrial DNA lasts from now through the end of the year.

These two factors combined mean strike while the iron is hot.

Prices for new tests and bundles are at an all-time low.

If you or your relatives have already taken a lower-level test, now is the time to upgrade to either the Big Y-700 or the mtFull Sequence test.

Step 1 – Test Yourself and Your Known Family

If you’re a male, order both the Big Y-700 test and mitochondrial DNA tests.

Be sure to click on “See More” for more useful tools.

When you receive your results, be sure to click on all of the tabs in your results, and do the same by clicking through to Discover from your account. Discover has 13 more goodies for you to help with your genealogy.

Both your personal page and Discover are essentially chapters of your own personal book about your DNA results. 25 very interesting chapters, to be precise, that are uniquely you.

I’ve written about understanding Y-DNA results here, and mitochondrial results here. My book, Complete Guide to FamilyTreeDNA, covers both along with Discover.

Discover provides robust information for Y-DNA haplogroups. If you’ve taken a Big Y-700 test, you’ll want to click through from your page to receive additional, personalized and more robust information than is available through the free public Discover tool. That said, the public version of Discover is an amazing tool for everyone.

After the new Mitotree is released for mitochondrial DNA, mitochondrial haplogroups will be available in Discover too.

I can’t even begin to stress how important these tools are – in particular the Time Tree, the Group Time Tree for members of group projects, and the Match Time Tree for your own matches.

Who Can Test For What?

Once you’ve tested yourself, you will want to take a look in your pedigree chart at branches further up your tree to see who can be tested to represent specific ancestors.

Let’s begin with my father’s side.

A mother contributes her mitochondrial DNA to all of her children, so your father carries the mitochondrial DNA of his mother.

If you’re a female, and your father is available to test, you’ll want to test BOTH his mitochondrial DNA and Y-DNA, because there’s no way for you to obtain that information from your own test. Females don’t have a Y chromosome, and men don’t pass on their mitochondrial DNA.

If you’re a male, you can test your own mitochondrial DNA and Y-DNA, but you’ll need to test your father’s mitochondrial DNA to obtain his mother’s. You might still want to test your father’s Y-DNA, however, because you may discover a personal family haplogroup. How cool is that??!! Your own tiny branch on the tree of mankind!

Your father’s mitochondrial DNA provides you with mitochondrial matches and haplogroup information for your paternal grandmother – in this case, Ollie Bolton.

If your father and his siblings can’t test, then all of the children of your paternal aunts carry your paternal grandmother’s mitochondrial DNA.

If they have no children or they can’t test, then the children of Ollie Bolton’s mother, Margaret Claxton/Clarkson all carry her mitochondrial DNA, and the children of Ollie’s sisters continue the line of descent through all daughters to the current generation.

The male children of Joseph “Dode” Bolton and Margaret Claxton carry his Y-DNA. Fortunately, that’s not one of our missing haplogroups.

Yes, you may have to climb up your tree and climb down various branches to find a testing candidate.

One of the reasons I’m using this example is because, while I have a high-level haplogroup for my grandmother, Ollie Bolton, we need a full sequence tester – and I’m offering a mitochondrial DNA testing scholarship for anyone descending from Margaret Claxton (or her direct female ancestors) through all females to the current generation, which can be male.

Ok, now let’s switch to the maternal side of your tree.

On the other side of your tree, your maternal grandfather or your mother’s brothers will provide the Y-DNA of your mother’s father’s line. Your mother’s uncles or their sons will provide your grandfather’s Y-DNA line, too. In this case, that’s John Whitney Ferverda, who carries the Y-DNA of his father, Hiram Bauke Ferverda/Ferwerda.

Your maternal grandfather or his siblings will provide the mitochondrial DNA of their mother, Evaline Louise Miller.

If they are deceased or can’t test, for mitochondrial DNA, look to the children of Evaline Miller’s daughters or their descendants through all females to the current generation, which can be male.

And yes, in case you’re wondering, I do need Evaline Miller’s mitochondrial line too and am offering a scholarship.

You might have noticed that I’ve been inching my way up my tree. All of my immediate relatives have passed over already, so I’m now looking for testers that I don’t know but who I’m related to.

If you’re seeing family members anytime soon, figure out if their Y-DNA, mitochondrial DNA, or autosomal DNA would be useful for your common genealogy. Take advantage of the opportunity.

Next, you’ll want to figure out which ancestors need haplogroups and locate appropriate cousins.

Step 2 – Identify Ancestors Who Need Haplogroups

Peruse your tree to determine which of your ancestors you need haplogroup information for. To make it easy, on my computer, but never in a public tree anyplace, I store the haplogroup of my ancestor as a “middle name” so I can easily see which ones I have and which ones I need. Sometimes, I have a high-level haplogroup and either need a new tester or someone to upgrade.

Sometimes, I have one tester from a line but need a second for confirmation.

In this example, I’m not missing confirmation on any Y-DNA haplogroups (although I am further upstream on different lines,) but I do need four different mitochondrial DNA lineages.

For easy reference, make a list of all of the lines you can’t confirm with two testers from different children of the same ancestor.

You just might get lucky and discover that someone has already tested!

Step 3 – Check FamilyTreeDNA Projects

Check FamilyTreeDNA Projects to see if someone has already tested to represent those ancestors on your list.

Click here for the Group Project Search. It’s located at the very bottom of the main FamilyTreeDNA page in the footer.

I’m going to use Estes as an example since I’m the volunteer administrator of that project and am very familiar with the lineages.

I’m searching for projects that include the surname Estes.

The projects displayed on the list are projects where the volunteer administrators listed Estes as a possible surname of interest. It doesn’t mean those projects will be of interest to everyone or every line with that surname, but evaluate each project listed.

You probably want the surname project, but if there’s not a surname project for your surname, try alternate spellings or consider checking other projects.

You can see at the bottom that 384 people of both sexes by the surname of Estes have tested at FamilyTreeDNA.

Now, let’s look at the Estes project. Note that not everyone with the Estes surname has joined the Estes project.

I’ve clicked on the “Estes” link which takes me to an additional information page where I can read a description and click to view the project.

For the Estes project, you do not have to join to view the results. Nor does your surname have to be Estes. All Estes descendants of any line are welcome. Everyone can benefit from the Advanced Matching within project feature to see who else you match within the project by selecting a wide range of individual and combined filters.

Click on the Project Website link shown in the search results.

If you’re searching for a male Estes ancestor, you’ll want to review the project’s Y-DNA Results and the Group Time Tree, for sure, and possibly the Map as well.

Let’s pretend I’m trying to determine if anyone has tested who descends from my ancestor, Abraham Estes, the founding Estes ancestor in Virginia who arrived in the mid-1600s.

In the Estes project, the volunteer administrator has divided the Estes male participants by sons of Abraham, the immigrant. Only three are shown here, but there are several.

Some of the participants have completed their Earliest Known Ancestor information, in the red box. Sometimes people don’t think to update these when they make breakthroughs.

If you descend from Abraham’s son, Sylvester, three men have taken the Big Y-700. That’s the test results you need.

If you descend from Abraham’s son, Abraham, no project participants have taken the Big-Y test to represent that line, although six people have tested, so that’s great news. Maybe you can offer an upgrade scholarship to one or some of those men.

In other words, to establish the haplogroup for that lineage, at least two men need to test or upgrade to the Big Y-700, preferably through two different sons of the common ancestor. A new, more defining haplogroup is often formed every two or three generations for Y-DNA.

Your genetic pedigree chart looks a lot like your genealogy pedigree chart.

Click any image to enlarge

The project Group Time Tree shows selected groups of men who have taken Big Y tests, along with their Earliest Known Ancestor, if they’ve provided the information. This is one of the reasons why the Big Y-700 is so critically important to genealogy. The time granularity is amazing and can answer the question of whether men by the same surname descend from the same common ancestor – and when.

If you’ve taken a Family Finder autosomal test at FamilyTreeDNA, or uploaded an autosomal file from another vendor, you may match one of these men or another male that descends from the Estes line if they, too, have taken an autosomal test.

This same process applies to mitochondrial DNA, but generally surname projects aren’t (as) relevant for mitochondrial DNA since the surname changes every generation. However, sometimes other projects, such as the Acadian AmerIndian Project are quite beneficial if you have Acadian ancestry, or a geographic or regional project like the French Heritage Project, or something like the American Indian Project.

Another great way to find testers is by utilizing your Family Finder test.

Step 4 – Family Finder at FamilyTreeDNA

The next step is to see if you match anyone with the surname you’re searching for by using your autosomal test results, so select your Family Finder Matches.

At FamilyTreeDNA you’ll want to search your matches by the surname you seek. This surname search lists any tester who has that surname, or anyone who has entered that surname in their surname list. Please note that this search does NOT read ancestors in your matches’ trees. You’ll still need to view trees.

Reviewing the 32 Estes Family Finder matches reveals several men, but one man with the Estes surname has already taken a Y-DNA 25-marker test, so he would be an excellent candidate to offer a Big Y-700 upgrade scholarship. If he’s not interested or doesn’t respond, there are several more men to contact.

Click on your match’s name to display the profile card, along with the Earliest Known Ancestors, both Y-DNA and mitochondrial DNA haplogroups if they have tested, and the assigned haplogroup based on their testing level.

Craft an email and offer a testing scholarship. This will help both of you. I’ll provide a sample email at the end of this article.

If you match a female with an Estes surname, her father, brother, uncle or cousin may either have already tested or be willing.

If you match someone who has a different surname, that means they have an Estes surname in their surname list and may know a potential tester. If your match has a tree, click to check.

I’ve found that matching through a company where you’ve both tested is the easiest way to encourage someone to take an additional test, but certainly, it’s not the only way.

Step 5 – WikiTree

WikiTree is a quick and easy way to see if anyone has taken Y-DNA or mitochondrial DNA test that should reflect a particular ancestor’s Y-DNA or mitochondrial DNA.

I just googled “Moses Estes 1711-1787 WikiTree” and clicked to view.

Each ancestor includes both Y-DNA and mitochondrial DNA information, in addition to people who descend from that ancestor through only autosomal lines.

In this case, two men have provided their Y-DNA results that pertain to Moses Estes. They have tested at different levels, which is why they have different haplogroups. That doesn’t mean either is “wrong,” one is just more refined than the other. You can correlate their kit number with the Estes surname project. People often don’t update their haplogroup information at WikiTree when it’s updated at FamilyTreeDNA.

Please note that if the genealogy is wrong, either at WikiTree or individually, the haplogroup may not reflect the appropriate lineage for the ancestor. Check to be sure that there’s no conflict showing between two testers for the same ancestor. For example, the same ancestor clearly can’t have two different base haplogroups, like E and R. The Discover Compare tool can help you evaluate if two haplogroups are in the same part of the Y-DNA tree.

When possible, it’s always best to test a close family member to represent your lineage even if someone else has already tested.

Scan down the list of autosomal testers for that ancestor to see if there’s someone with the Estes surname.

WikiTree provides additional tools to find descendants.

Sign in to WikiTree. You’ll see the ID of the profile you’re viewing – in this case – Estes-167. Click the down arrow and select “Descendants.”

This view shows all descendants through five generations, but you can click on DNA Descendants to see only Y-DNA descendants, X-DNA, or mitochondrial DNA descendants for female ancestors.

You may find people who are living and have added themselves who you can contact to offer a DNA testing scholarship.

Step 6 – MyHeritage

At MyHeritage, you can also search your DNA matches by surname.

Click on “Review DNA Match” to view more detail, including locations. Look to see if you have a Theory of Family Relativity Match which suggests how you may be related. That’s golden!

There’s no Y-DNA information at MyHeritage, BUT, you can search by surname and view DNA matches that either carry that surname or have that surname in their tree as an ancestor.

I have a total of 75 “Estes” matches, and other than the kits that I manage, searching through my matches shows:

  • Two Estes men connected to the same small tree, but that’s OK, I’m a genealogist!

  • One Estes male match with a Theory of Family Relativity. My lucky day!

You can contact your match easily through the MyHeritage messaging system and offer a DNA testing scholarship at FamilyTreeDNA. You may also want to share your email address.

MyHeritage customers may not be familiar with Y-DNA or mitochondrial DNA testing, so you might want to share this article about the 4 Kinds of DNA for Genealogy.

MyHeritage testers can also upload their DNA file to FamilyTreeDNA for free to receive autosomal matches plus a complimentary mid-range Y-DNA haplogroup. This free haplogroup is not even close to the detailed resolution of a Big Y-700 test, but it’s something, and it may well be an enticing first step for people who are only familiar with autosomal testing.

Step 7 – At Ancestry

At Ancestry, select DNA Matches and then search by surname.

You can search by the surname of the tester, which is very useful, or by people who have Estes in their trees.

I started with the surname Estes, because it’s the most straightforward and I may find a perfect male candidate for Y-DNA. If someone’s “screen name” doesn’t show as Estes, they won’t appear in the results of this search. In other words, if your Ancestry screen name is “robertaestes” you won’t show in this search, but “Roberta Estes” will.

For mitochondrial DNA, you would want to search for the surname in your matches’ trees. Unfortunately, you cannot search for the specific ancestor in someone’s tree, at least not directly.

Of my 19 Estes surname matches, ten are males, and of them:

  • Three have unlinked trees
  • Three have very small linked trees, but I can work on extending those if need be
  • Three have public linked trees AND a common ancestor, which means ThruLines

I can review which ancestor we share by clicking on my match’s name

The Estes side of this man’s tree has only one person and is marked “private,” but Ancestry has suggested common ancestors based on other people’s trees. (Yes, I know trees are dicey, but bear with me.)

It’s also worth mentioning that you can be related through multiple lines. I share surnames from Acadian lines with this man, but that really doesn’t matter here because I’m only using autosomal matching to find an Estes male.

Click on “View Relationship” to see our common Estes ancestor’s ThruLine.

The ThruLine shows how Ancestry thinks we’re related on the Estes line.

I can also click on “View ThruLines” to see all Thrulines for John R. Estes, which shows four additional males, some of which did NOT appear in the Estes surname search, and some of which don’t appear further up the tree. In other words, check all Estes ThruLine ancestor generations.

Don’t rely solely on Ancestry’s surname search.

Go directly to your ThruLines on the DNA menu.

Ancestry only reaches back seven generations, which for me is Moses Estes and Luremia Combs. Moses has 95 matches, but he has been given some incorrect children. Again, for this purpose, it doesn’t matter. Within all ThruLine matches, I found three Estes males who all descend through John R. Estes. Check every generation.

However, Luremia Combs shows promise for mitochondrial DNA descendants. Unfortunately, only two of her daughters are represented in ThruLines, and both of their descendants descend through Luremia’s grandsons. That’s too bad, because I need Luremia’s mitochondrial DNA line.

It’s easy to message your Ancestry matches. You may want to mention that they can upload their DNA file to FamilyTreeDNA for free where they will receive more matches and males will receive a complimentary mid-level Y-DNA haplogroup.

Please note that, in general, ThruLines need to be evaluated very carefully and are prone to errors, especially if you accept Ancestry’s suggestions of ancestors instead of carefully building out your own tree. Regardless, you can still find Estes cousin matches in your match list and by using ThruLines to find people that do not show up in an “Estes” match search.

Step 8 – At 23andMe

At 23andMe, you can search for anyone who either has the Estes surname or has included that surname in their “Family surnames” list. Keep in mind that your matches at 23andMe are restricted to either 1500 if you don’t have a subscripition, or about 4500 if you do have a subscription.

On my match list, I have two males with the Estes surname.

23andMe provides a mid-level Y-DNA haplogroup. You can’t use this to confirm the lineage when comparing with FamilyTreeDNA, especially given that 23andMe provides no genealogy or user-provided tree, but it is a clue.

Both Estes men at 23andMe have Y-DNA haplogroup R-CTS241. You could use this in some cases to potentially eliminate these matches at 23andMe. For example, if men in your lineage in the Estes project are in haplogroup R and your 23andMe matches are showing as haplogroup E, or any other base haplogroup, their common ancestor is tens of thousands of years ago.

Comparing the 23andMe haplogroup, which in this case is about 4500 years old, to contemporary testers who have taken the Big Y-700, which reaches within a few generations, isn’t terribly useful. These matches are extremely useful to identify individuals to reach out to for further information and potentially offer a Y-DNA testing scholarship at FamilyTreeDNA.

Remember, this also applies to females who have included Estes in their family surnames, given that they may have Estes male relatives.

By clicking to view your match, you can see if they have provided Family Background information, including a link to a family tree someplace.

Sometimes, there’s great information here, and other times, nothing.

You can’t verify this lineage without genealogy information.

I suggest leaving a genealogy-focused message, including where they can see your tree in addition to your Estes connection. Also include your e-mail.

You may want to say that if they descend appropriately, you have a Y-DNA or mitochondrial DNA testing scholarship, or you may want to wait to see how they descend. You can also ask if they have already taken a Y-DNA or mitochondrial DNA test at FamilyTreeDNA.

Step 9 – FamilySearch and Relatives at RootsTech

We’re getting ready for RootsTech 2025 which takes place in March. In the month or so before the last two RootsTechs, FamilySearch provided an absolutely wonderful tool called “Relatives at RootsTech.”

I’ve written about this several times, but essentially, you can see, by ancestor, other people who are registered both in-person and virtually for RootsTech, and how they descend.

Here’s an example.

In both years, I’ve found several people who descended from common ancestors AND were very willing to take the relevant DNA test. That’s a huge win-win for everyone.

The best part is that because these people have freshly registered for RootsTech, the reply rate is almost 100%.

I’ll write about this as soon as RootsTech makes it available this year. Fingers crossed that they do!

Step 10 – Social Media

Social media wouldn’t be my first choice to find DNA testers, but I have found perfectly willing cousins this way. You may be less successful on Facebook or other social media platforms, but if you’re striking out elsewhere, there’s absolutely no downside to trying.

You can enter a surname and search on Facebook, but I prefer to do a Google search like “Estes genealogy on Facebook” or even just “Estes genealogy,” which will produce far more widespread information, some of which may be irrelevant.

That Facebook Google search provided the names of two groups. People join groups because they have an interest, and I’ve had good luck in Facebook genealogy groups.

A Search of “Estes” on Facebook itself, then selecting “people” provided a list of Estes Facebook users.

I’ve had far better luck by joining a group that is focused on Estes genealogy, or even a county genealogy group that includes Estes families, than individuals. People who join any Estes group or project likely have an interest in that surname.

If you have a common surname, or there’s a park named after your surname, like Estes Park, you’ll probably want to focus by using Google searches for Estes genealogy.

The Descendants of Abraham Estes Facebook group has 222 members, of whom at least 31 are males with the Estes surname. Facebook just might be an underestimated resource.

If there isn’t a genealogy-focused group for your surname, you might want to consider starting one and encouraging people to join.

It can’t hurt, and it just might help. Before you start reaching out to random people on Facebook, please do a privacy checkup – I wrote about how, here.

Sale Prices

Remember, the sale prices at FamilyTreeDNA for new tests and upgrades last through year-end.

In my experience, it’s best to test as soon as someone agrees. You never know what will happen otherwise. I’ve had people pass away before they could swab. And yes, we’ve done funeral home swabs, too.

There’s no one-size-fits-all, but here’s a rough draft contact letter.

Potential Contact Letter

You’ll want to include several critical pieces of information.

Essentially:

  • Introduce yourself
  • Say their full name on their test AND the testing company in the title of an email. I manage many tests and if I receive an email that says, “Hi, can you tell me how we match” without telling me which person they match, I can’t even begin to answer.
  • Explain your genealogy connection
  • State your purpose in writing
  • Explain how a specific test will help them too
  • Offer to answer questions

Be sure to modify this letter to reflect your own voice and circumstances. You don’t want this to read like a form letter.

Dear cousin (insert their full name here,)

It was so nice to find our DNA match at <company name> (or we share a common ancestor, or appropriate circumstance.) (If you are managing someone else’s kit, say the name of who they match and explain that you manage their DNA kit.)

I descend from (ancestor plus birth and death date) who lived in Halifax County, Virginia and was married to (spouse.) You can view my tree at (insert link that does not require a subscription for viewing unless you match them on that platform. I use MyHeritage because everyone can view their trees)

I would very much like to confirm that our line descends from Abraham Estes (or relevant information meaning your reason for wanting them to test.)

Given that my surname is x (or I’m a female), we need to test the Y-DNA of a male who is descended from (ancestor) through all males to the current generation. (Or mitochondrial DNA descended through females to the current generation which can be male.)

FamilyTreeDNA provides this testing and shows who you match on that specific line using the Y chromosome (mitochondrial DNA).

This testing may connect us with earlier ancestors. Genetics can be used to determine when we share common Estes ancestors with others who test, where we come from overseas, and when. Even if we match ancient DNA samples that may tell us where our ancestors lived before surnames. In other words, where did we come from?

(Include a nice paragraph, but not a book about your ancestral lineage here.)

I have a DNA testing scholarship for someone from this line and you are the perfect candidate. I would like to take advantage of the current sales. If you’re interested, I only need two things from you.

First, permission so that I can order (or upgrade) and pay for the test, and second, an address where to send the test (unless it’s an upgrade). (If it’s an upgrade at FamilyTreeDNA, they can use a stored sample or will sent them a new kit if there’s not enough DNA.)

If you have any questions, please let me know. I’m very excited that we may be able to learn more about our heritage.

Please email me at xxx or call me at xxx if you have questions.

Your name

I know one person who offers to review results over Zoom. Someone else stresses that the tester’s email is attached to their test and they are always in control of their results. Another person asks them to join a project they manage to assure that they can follow their matches over time.

Customize this communication in your own voice and to fit the circumstances of each match.

It’s just me, but since I’m ordering while the tests are on sale, unless the person uploads their DNA file from another vendor, I add on a Family Finder test too and explain why. You never know if they will match you or another cousin, and they may have that match that eventually breaks down the next brick wall. Shared matches are powerful evidence and it’s a lot easier to add that test on now than try to contact them again later.

You Don’t Know What You Don’t Know

Which ancestors do you need Y-DNA or mitochondrial DNA results for? Methodically check each line.

There’s so much to learn. Don’t leave information on the table by virtue of omission.

Leave no stone unturned!

You don’t know what you don’t know.

Who’s waiting out there for you?

Why Don’t Our Y-DNA Haplogroups Match?

I’ve been asked this question several times recently, and the answer is resoundingly, “it depends.” There are several reasons why Y-DNA haplogroups might not match and most of them aren’t “bad.”

How Haplogroups Work

Haplogroups are the 79,000+ branches of the Y-DNA phylogenetic tree which you can view here, along with countries where those haplogroups are found. You can think of haplogroups as genetic clans of either closely or distantly related men. Major haplogroup branches have unique letters assigned. Downstream or younger haplogroups are designated by a letter-number sequence that is always preceded by the main haplogroup letter.

Image courtesy FamilyTreeDNA

Major haplogroups were formed tens of thousands of years ago, with more recent haplogroups added as they’ve been discovered. Haplogroups are discovered and added every day thanks to the Big Y-700 test. You can read more about that process, here.

As you look at the pie chart above, you’ll notice that haplogroup R represents about half the men who have tested and has several major subbranches. Every haplogroup R man belongs to all of the branches above his own that lead back to the root of haplogroup R.

Using haplogroup R, which is R-M207, its identifying SNP, as an example, it immediately splits into two branches: R-M173, which has 37,000+ more branches, and R-M479, which has 313 branches. My Estes men fall into a haplogroup several steps beneath R-M173, but they are still members of haplogroups R-M173 and R-M207, even though their descendant haplogroup is R-BY490, which was formed by a mutation that occurred 20,000 years later.

Haplogroup R-M173, then, in turn, leads back to Y-Adam, the first man to have lived and has descendants today.

As we approach the question of why haplogroups of two men might differ, we will review tools to use and how to interpret your findings to reach the appropriate answer for your situation.

What is Your Goal?

You may be looking for a very specific answer, or this may be a more general question.

  • If you’re evaluating closely related men who have different haplogroup assignments, not matching can be very disconcerting. Breathe. There are several perfectly legitimate reasons why they may not match, and we have easy, free analysis tools.
  • If you’re looking at your Y-DNA match list at FamilyTreeDNA, you may or may not match other men closely, but you do “match” at some level if they are on your match list. You may see several different haplogroups in your match list. How closely you match those men is a different question.
  • If you’re looking at autosomal results at FamilyTreeDNA, you may see haplogroups listed for males. You may or may not “match” the haplogroup of men with the same surname. What does this mean, and why don’t you match? Your autosomal match may have nothing to do with your paternal line, or it may be because of your paternal line.

We will cover all of these scenarios.

Where Did You Both Test?

  • Are you comparing apples and apples?
  • Did you both test at the same company?
  • Did you both take the same type or level of test?

These factors all make a difference.

Which Test Did You Take?

There are four types of tests that will provide males with some level of Y-DNA haplogroup.

Autosomal Tests – Some companies include a few Y-DNA location probes in their autosomal test, meaning that they test a few haplogroup-specific Y-DNA locations. LivingDNA, 23andMe, and FamilyTreeDNA’s Family Finder test provide a mid-level Y-DNA haplogroup to customers. The haplogroup that can be determined from these tests depends on a variety of factors, including the vendor, the probes they selected for their chip, the test version, and if that location is successfully read in the test.

Note that FamilyTreeDNA supports autosomal uploads from MyHeritage and Ancestry who do not provide Y-DNA haplogroups to customers, but who do test some Y-DNA locations. Therefore you can upload your autosomal test from those companies to FamilyTreeDNA for free and receive at least a cursory Y-DNA haplogroup.

FamilyTreeDNA is currently processing all of its Family Finder tests, followed by tests uploaded from other vendors, to provide all genetic male testers with a Y-DNA haplogroup at some level. Different vendors and test versions test different Y-DNA SNPs, so your mileage may vary. Y-DNA haplogroups are a free benefit at FamilyTreeDNA.

STR Tests – At FamilyTreeDNA, you can purchase both Y-37 and Y-111 STR (short tandem repeat) Y-DNA tests that provide matching at the number of locations you purchased, plus a predicted haplogroup based on those results. These haplogroup predictions are accurate but are often relatively far back in time.

If you match someone on STR tests, your match may be very recent or before the advent of surnames. For a more specific haplogroup, you need to purchase the Big Y-700 test, which provides at least 700 STR match locations but, more importantly, sequences the entire gold-standard region of the Y-chromosome for the most precise haplogroup and matching possible.

  • When viewing matches of two men who ONLY took STR tests, STR marker matches are more important for genealogy than haplogroups because the haplogroups were formed thousands of years ago.
  • When viewing matches on the Big Y-700 test, haplogroup matching is much more specific and reliable than STR matches because the mutations (SNPs – single nucleotide polymorphisms) that form haplogroups are much more stable than STRs which mutate unpredictably, including back mutations.

SNP Confirmation Tests – Historically, FamilyTreeDNA customers could purchase individual SNPs to confirm a haplogroup, or SNP packs or bundles to do the same for a group of SNPs. With the advent of both the Family Finder haplogroup assignments, and the Big Y-700, these individual tests are no longer necessary or advantageous and are being discontinued.

Big Y-700 Test – At FamilyTreeDNA, the Big Y-700 test provides the most granular and specific haplogroup possible, most often well within a genealogical timeframe. You may be able to tell, based on previously undiscovered mutations, that two people are brothers or father and son, or, depending on who else has tested and when mutations formed, testers may match further back in time. Here’s an example of using the results from multiple testers in the Estes DNA Surname Project.

You can also match men who took the Big Y-500 test which is less specific than the Big Y-700. In the now-obsolete Big Y-500 test, a smaller portion of the Y chromosome was sequenced and testers only received about 500 STR locations. The Big Y-700 test has been enriched to provide a wider range of more specific information. Men who originally took the Big Y-500, then upgraded to the Big Y-700, will very probably have a new haplogroup assignment based on the expanded coverage and increased resolution of the Big Y-700 test. The Big Y-700 ferrets out lineages that the Big Y-500 simply could not, and continues to provide additional value as more men test, which facilitates the formation of new haplogroups.

What Do You Mean by Match?

Matching doesn’t mean you have to have the exact same haplogroup. A perfectly valid match can have a different haplogroup because one haplogroup is more specific or refined than the other. Matching exactly as a result of a predicted STR haplogroup is much less useful than matching closely on a much more recent Big Y-700 haplogroup.

Not all haplogroups are created equal.

I know this is a bit confusing, so let’s look at real-life examples to clarify.

STR to STR or Autosomal to Autosomal Haplogroup Match

Two males might match exactly on a mid-range Family Finder autosomal haplogroup or on a STR-predicted haplogroup like R-M269, which is about 6350 years old.

This haplogroup “match,” even though it might be exact, does not confirm a close match and really only serves to eliminate some other haplogroups and confirm that a closer match is possible. For example, R-M269 men don’t match someone in haplogroup J or E. You may or may not share a surname. You may or may not still “match” if you both upgrade to the Big Y-700.

In this case, a father/son pair would match exactly, as would two men with different surnames whose common ancestor lived 6000 years ago.

Note that if you’re comparing autosomal-derived haplogroups across different vendor platforms, or even different DNA testing chip versions on the same platform, you may see two different haplogroups. Different vendors test different locations. Please note that second cousins and closer will always match on autosomal DNA, but relationships further back than that may not. Y-DNA very reliably reaches far beyond the capabilities of autosomal DNA due to the fact that it is never mixed with the DNA of the other parent – so it never divides or is watered down in time. When comparing two autosomally-generated haplogroups of men who are supposed to be closely related, always check their autosomal match results too.

Use the free Discover Tool to find various categories of information about any haplogroup, including its age. Take a look at R-M269 here.

Using Discover to Compare Haplogroups

You can always use the Discover tool to compare two haplogroups.

Go to Discover (or click through if you’re signed on to your FamilyTreeDNA Y-DNA page), then enter the first haplogroup you’d like to compare.

Click search to view information about that haplogroup.

On the menu bar, at left, click on Compare.

Add the second haplogroup.

I’m selecting E-M35, a completely different branch of the phylogenetic tree.

R-M269 was formed about 6350 years ago, while E-M35 was formed about 25,000 years ago. Their common ancestor was formed about 65,000 years ago. Clearly, these two paternal lineages are not related in anything close to a genealogical timeframe.

These two men would never match on an STR test, but could easily match on an autosomal test on any line OTHER than their direct paternal line.

Now let’s compare two haplogroups that are more closely related.

Haplogroup R-M222 is very common in Ireland, so let’s see how closely related it is to R-M269 which is very common in western Europe.

We see that R-M222 descends from R-M269, so there is no “other haplogroup” involved.

R-M222 was formed about 2100 years ago, around 4250 years after R-M269 was formed.

There are 17 steps between R-M222 and R-M269.

The bottom block shows the lineage from R-M269 back to Y-Adam.

How cool is this??!!

Big Y-700 to Autosomal or STR Haplogroup Comparison

Joe took the Big Y-700 test and discovered that he’s haplogroup R-BY177080.

Joe noticed that his son, who had initially taken an STR test, had been assigned haplogroup R-M269. Then, his son took a Family Finder test and his haplogroup changed to R-FGC8601.

Joe was confused about why he and his son’s haplogroups didn’t match.

First, let’s check Family Finder to confirm the parent/child relationship. Joe’s son is clearly his son.

So why doesn’t Joe’s son’s haplogroup match Joe’s haplogroup? And why did Joe’s son’s haplogroup change?

Joe’s son had not taken a Big Y-700 DNA test, so Joe’s son’s R-M269 haplogroup was initially predicted from his STR test.

Joe’s son’s updated haplogroup, R-FGC8601 was generated by the Family Finder test. Think of this as a bonus. If you’re a male and haven’t yet, you’ll soon receive an email telling you that you’ve received a Family Finder Y-DNA haplogroup. It’s your lucky day!

Family Finder haplogroups always replace STR predicted haplogroups since they are always more specific than predicted STR haplogroups. Big Y-700 haplogroups always replace STR-generated haplogroup predictions and Family Finder haplogroups because they are the most specific.

Let’s compare these results using Discover.

Joe’s son’s original predicted haplogroup was R-M269.

Discover Compare shows us that Joe’s Big Y-700 Haplogroup, R-BY177080, is a descendant of R-M269.

So, they actually do “match,” just several branches further up the tree

Joe’s son’s more precise Family Finder haplogroup was assigned as R-FGC8601.

Discover Compare shows us that Joe’s Big Y-700 haplogroup also descends from R-FGC8601.

You can see that the haplogroup generated by Family Finder is more precise by about 4700 years and improves that comparison.

R-M269 was formed about 6350 years ago, but R-FGC8601 was formed about 1700 years ago.

Joe’s Big Y-700 haplogroup, R-BY177080 was formed about the year 1900, improving the family haplogroup by another 1600 years or so.

Joe’s son’s Family Finder haplogroup moved down the haplotree 21 branches and 4650 years, for free! If Joe’s son were to upgrade to the Big Y-700, they might very well be assigned a new haplogroup that, for the time being, only they share.

Of course, Family Finder doesn’t provide Y-DNA matching so you still need the Y-DNA tests for that important aspect of genealogy.

Big Y to Big Y Comparison

In our next example, a group of men, including a father and son or other very close relative may take the Big Y-700 test and have different haplogroups. If you’re saying, “Whoa Nelly,” hear me out.

George took a Big Y-700 test and discovered that he is haplogroup R-FGC43597. His son and grandsons tested, and they are haplogroup R-FTC50269. What happened? Shouldn’t they all match George?

On George’s Big Y-700 block tree, you can see that a mutation, R-FTC50269, occurred between George and his son. George doesn’t have it, but his son does.

A haplogroup isn’t “named” until there are two men with the same mutation in the same lineage. Therefore, when George’s son initially tested, he would have been assigned to the same haplogroup as George, R-FGC43697, but with one extra variant, or mutation.

Of course, that extra mutation was passed from George’s son to both of his grandsons, so when the first grandson tested, the new haplogroup, R-FTC50269 was assigned as a result of that mutation. Now, George has one haplogroup and his son and grandsons have a different haplogroup, one branch downstream.

Using Discover to check the haplogroup ages and path, we find that indeed, these haplogroups are only one step apart.

Checking Family Finder results can always verify that the match is close or as close as you expected.

Haplogroup Assignments

Haplogroup assignments range from good to better to best.

Good Better Best
STR predicted Yes – but further back in time
SNP Packs (now obsolete) Between good and better
Family Finder autosomal Yes – generally midrange between STR predicted and the Big Y-700
Big Y-500 (need to upgrade) Usually between better and best
Big Y-700 The best – usually within a genealogically relevant timeframe unless your DNA is rare

Where Are You?

Older haplogroups, such as the STR-predicted haplogroups are useful for:

  • Eliminating some potential matches
  • Identifying where that haplogroup originated at that specific point in time. In other words, where your ancestor lived when that haplogroup was born.

If your Y-DNA matches another Y-DNA tester at FamilyTreeDNA, your haplogroups will fall someplace on the same haplogroup branch, although they may be thousands of years apart. STR-predicted haplogroups are “older,” meaning they range in age from about 6500 years to tens of thousands of years ago. They can tell you where the haplogroup originated at that time.

Autosomal haplogroups will be newer, or more recent, than STR-predicted haplogroups, but still (sometimes significantly) older than the Big Y-700 haplogroups..

FamilyTreeDNA provides Y-DNA haplogroups for free for every biological male who either takes the FamilyTreeDNA Family Finder test or uploads an autosomal result from either Ancestry or MyHeritage. Soon, 23andMe uploads will be resumed as well. This means that you will be able to view other men with a similar surname in your Family Finder results and:

  • Rule them out as a paternal line match.
  • Check your STR matches if they have taken a Y-DNA test
  • Check your Big Y-700 test for matches if both men have taken a Big Y test.
  • Encourage your matches to take a Big Y-700 test so you can see how closely you match on your paternal line.
  • Use the Discover Compare and other tools to reveal more information.

Family Finder haplogroups are relatively new, so currently, all new Family Finder testers are receiving haplogroups. Older Family Finder tests are being processed and will be followed by autosomal tests uploaded from other vendors. Haplogroups from autosomal tests are confirmed and will be newer, or more recent, than STR-predicted haplogroups.

The only test that can bring your haplogroup to current, meaning the most refined, recent, personal haplogroup, is the Big Y-700 test. Without taking the Big Y-700 test, you’ll forever be stuck with an older, less informative haplogroup branch. The Big Y-700 allows us to reliably sort families into lineages based on branching mutations.

The Big Y-700 haplogroup is:

  • The most detailed and granular possible.
  • Determined by sequencing the Y chromosome.
  • A test of discovery that continues to provide additional value as more men test and new haplogroups are formed.

Big Y-700 haplogroups generally fall into a genealogically useful timeframe and can be very recent.

The Discover tool and Time Tree provide a wealth of information about your ancestors, including locations, migration paths, ancient DNA, and more.

You Don’t Know What You Don’t Know

Now that you understand how to compare and interpret haplogroup matches, what additional information can you learn?

I always encourage Y-DNA matches to upgrade to the Big Y-700. Why? You don’t know what you don’t know. The article, Bennett Greenspan: Meet My Extended Family & Discover Extraordinary Deep Heritage illustrates the benefits of the Big Y-700 for all matches. Upgrading 12-marker matches is exactly how he made his big breakthrough.

The Big Y-700 test answers many questions beyond simply matching by using Discover and the Group Time Tree.

  • Where were your ancestors?
  • Who do you match, and who were their ancestors?
  • Genetically and genealogically, how do your surname matches fit together?
  • Where were your matches’ ancestors, and when?
  • Which ancient DNA results do you match, and where were they located?
  • What is the history of locations where your ancestors were found along their journey?
  • How closely or distantly are you related to other Big Y-700 matches?
  • Can your matches’ information break down your paternal line brick wall, or at least move it back a few generations?

Where are your Y-DNA results along the spectrum of useful haplogroup information? Do you or your matches need to upgrade? Click here to upgrade or order a Big Y-700 test.

Bennett Greenspan: Meet My Extended Family & Discover Extraordinary Deep Heritage

“My ancestors are in my soul. I can’t get them out of my mind.”

Bennett Greenspan

“And yes, I brake for cemeteries.”

Bennett Greenspan gave an incredibly interesting presentation at the 15th International Genetic Genealogy Conference held by FamilyTreeDNA in November 2023. Since his retirement in January 2021, he has been able to focus on his genealogy. Once a genealogist, always a genealogist.

Bennett said some things I hadn’t thought about, and now I’m viewing Y-DNA matches with a different perspective – based on how he’s using his results.

Ever since I met him, Bennett’s focus has been to use genetics to unravel his complex Jewish heritage.

The questions that drive Bennett are the same ones that motivate most genealogists:

  1. Who are we?
  2. Where did we come from?
  3. Where were we before we were there?
  4. How did my ancestors get there?

Bennett “lost his family lines” before the mid-1800s due to his Jewish heritage, exacerbated in the 1930s by the devastation wrought by the Holocaust. Families were either killed or scattered to survive. It has been through Y-DNA in particular that he has been able to establish unquestionable and confirmed connections with other Greenspan men, sometimes by similar but different surnames, like Green, and sometimes with other surnames entirely.

When Bennett first started down this path, he tested more than 62 men before actually finding one a decade later that matched his Y-DNA. Bennet commented that it was “a little frustrating.”

Persistence is the key, and sometimes, genealogy is a waiting game, but that’s small comfort to genealogists during that unproductive waiting period.

Eventually, Bennett reassembled his family, at least somewhat, but it was a long journey. Here’s Bennett’s incredible story, including surprises, as he tells it.

Bennett discovered genealogy at age 12 and, like many genealogists, created a pedigree chart by talking to his family.

I love the mark-outs. How many of us still have our first chart with its edits?

This is the young Bennett Greenspan, whose interest in genealogy would one day unlock secrets for all of us!

It was a long way from a decade with no matches to finding his genetic kin in Ukraine.

The Big Y-700 Time Tree shows Bennett’s lineage in Ukraine, but stepping back in time, some descendants of his ancestors are found in adjacent locations.

Bennett was passionately discussing his matches on the time tree and in the Greenspan project, so I visited the Greenspan DNA Project, where the earliest known ancestors of Bennett’s Big Y matches are shown on the Group Time Tree.

Bennett’s closest matches are shown as descendants of haplogroup J-ZS1718. He has additional matches who are not in the Greenspan project. Since this is the Group Time Tree, it only displays the people in that project, along with their earliest known ancestors, Isaac and Usher Greenspan.

12-Marker Matches

Bennett never fails to amaze me. He said something very important and profound about 12-marker matches that I really hadn’t thought about – at least not this way.

As a community, we are often guilty of discounting 12-marker matches, those that don’t match us at 25-markers or above, or with different surnames, as “too far back in time” or otherwise irrelevant. I always look at the names and earliest known ancestors of 12-marker matches, because that person may have tested back in the day when fewer markers were available. But if I don’t recognize something, I move on.

However, Bennett said that, ”Y-12 matches reach back to a common ancestor. 12-marker matches are not a quirk. They are related to you, just further back in time. You share a common ancestor with them, someplace. They may be more distant, but they are still your close matches.”

I’ve been in too much of a hurry for a quick win, and ignoring the (apparently not so) obvious.

Determining when and where their ancestors lived also paves the way to discover yours. Your Y-DNA and theirs were in the same place at the same time.

Of Bennett’s 171 12-marker matches, 107 have upgraded to the Big Y, probably mostly due to his encouragement. This benefits both them and Bennett by fleshing out the history of that entire group of men, including how they got to where they are found in the first available records. The Time Tree shows when Big Y testers shared a common ancestor, and based on Earliest Known Ancestor (EKA) locations, where. This provides further information about the lives of ancestors before contemporary records – in other words – people that we can never identify by name. It’s a window into ancestors before surnames.

Bennett notes that testers need to know their ancestral village or location to be most useful within the project, and of course, they need to enter their EKA information. Location information is how the Migration Map, Matches Map, and Discover tools, including the Time Tree, are built.

What Happened in Spain?

Bennett’s ancestors and those of his 12-marker matches are found in Spain, and as Bennett says, “One son stayed and one left about the year 296.”

While we have no idea of their names, based on the Time Tree combined with the cluster of earliest known ancestors, we know that they were in Spain, and when.

Their family story is revealed in the bifurcation of the tree found beneath haplogroup J-L823, formed about 296 CE. One line stayed in Spain, and Bennett’s line migrated to eastern Europe where that man’s descendants, including Bennett’s family, are found in the Russian Federation, Belarus, Poland, Lithuania, Sweden, Slovakia, Ukraine, Germany, Romania, the Czech Republic, and other eastern European locations. The closer to you in the tree and in time, the more relevant to your more recent ancestral story.

However, Bennett’s deeper ancestry, the migration of his ancestors to Spain, was only revealed by testing those more distantly related men. Those same men could well have been ignored entirely because they only matched at 12 markers.

According to Bennett, “Y-12 markers are important because these are the men most closely related to you in a database of 1 million men.”

How incredibly profound. How much have I been cavalierly overlooking?

How does this actually apply to Bennett’s results?

Bennett’s Spanish Matches

Bennett has the following STR panel matches who indicate that their EKA are from Spain. You can see that they match Bennett on a variety of panels.

  • X = yes, match
  • No = no match
  • Blank = not tested at that level.

In the Big Y GD column, the genetic distance (GD) is displayed as 15/660 where 15 is the number of mismatches, or the cumulative genetic distance ABOVE the 111 panel, and 660 is the number of STR markers above 111 with results.

The Big Y-500 test guaranteed a minimum of 500 total STR markers, and the Big Y-700 guarantees a minimum of 700 total STR markers, plus multiple scans of the balance of the Y chromosome for SNP mutations that define haplogroups. Testers don’t receive the same number of markers because the scan technology sometimes doesn’t read a specific location.

Of those 23 Spanish matches, sixteen have upgraded to Big Y tests, 14 of which are Big Y-700s, resulting in nine different haplogroups, all of which are descendants of Haplogroup J-L823. How cool is that?

The “Nos” in the Big Y Match Column aren’t mistakes. That’s right – none of these men match Bennett on the Big Y test, meaning they had more than a 30 mutation difference between them and Bennett on the Big Y test.

At first glance, you’d think that Bennett would have been disappointed, but that’s not the case at all! In fact, it was the information provided by these distant Spanish matches that provided Bennett with the information that his line had split sometime around the year 296 CE, with one branch remaining in Spain and his branch migrating to Eastern Europe, where he has lots of matches.

DNA Plus History

What was happening in Spain or the Iberian peninsula that involved the Jewish people about that time? Historical records exist of Jews living in that region before the fall of the Second Temple in about 70 CE, including records of Jews being expelled from Rome in 139 for their “corrupting influence.”

Furthermore, the Ancient DNA Connections for haplogroup J-L823, the most recent common ancestor (MRCA) for all of those branches, includes connections to multiple burials from:

  • Lebanon
  • Iran
  • Rome (from 1-400 CE)
  • Turkey
  • Jordan

Clearly, Bennett’s ancestor was in the Iberian peninsula around or before 296 CE. One branch stayed, winding up in Spain, and one headed for Europe.

Without these matches, some who didn’t match above the 12 or 25 marker level, how would Bennett have EVER known that his Jewish ancestors left the Middle East for Spain in the early years? How would he have known they migrated from Spain to Eastern Europe, and how would he have known that his line did not migrate directly from the Levant to Eastern Europe in the 9th century?

Big Y matches are typically within about 1500 years, but non-matches are still INCREDIBLY valuable. Without them, you can’t completely assemble your family story.

I noticed on the Time Tree that in Bennett’s Eastern European line, one of his ancestor’s brother lineages includes the Katzenellenbogen Rabbinic Lineage derived from ancient DNA samples.

Bennett’s successes have resulted from contacting his matches and encouraging upgrades. So how did he do it? What’s the magic sauce?

Contacting Matches

How to contact matches successfully is a question I see often. In fact, FamilyTreeDNA recently wrote about that in an article, here.

Bennett’s methodology for contacting his matches to encourage an upgrade is that he sends an email explaining why he’s encouraging them to upgrade, followed by a 2nd email three days later.

Bennett tells the recipient that we are at an inflection point in time. “It’s winter, the wind is blowing hard, and many of the leaves are gone.”

In other words, we need to cast the net wider and capture what we can, while we can. Unfortunately, many early testers have died, and with them, chapters of history are perishing.

Collaboration is key. In addition to encouraging upgrades, Bennett also offers Zoom calls to these groups of men to explain the results if they are interested.

What a GREAT idea! I need to begin offering that as well.

Upgrade Request

Bennett reaches out to his matches at various levels, but he expects his closer STR matches, meaning at the 67 and 111 marker level with the fewest mismatches, to match him on a Big Y-700 test and connect someplace between 300-600 years ago, which helps everyone flesh out their tree.

Bennett’s email:

Hello <name>,

Since you have already made a sizable investment in your Y-DNA, you now know that we come from the dominant male Middle Eastern group (Haplogroup J) of men who <subject here>.

What’s really neat is that our Y-DNA has recently been found in an archaeological site in Northwestern Jordan dated to about 4200 years ago. I know this because I upgraded to the Big Y, which tests SNPs, looking at several million locations on the Y chromosome of each man.

One academic customer recently compared this new technology as the difference between looking into space with binoculars versus the Hubble Telescope.

I don’t know if you are familiar with your list of matches at the highest level you’ve tested for, either Y-67 or Y-111. If you are, you should recognize my name and the names of others who have taken the Big Y test.

You’ll see what you’ll gain by letting me upgrade your test for you and determining whether you are related to my line – probably between about 200 years and 500 years.

This might be the second time that I have written to you on this matter; can I presume if I don’t hear from you that you’re not really interested in the Y-DNA subject anymore?

Can I run the test so that I can see how closely we are related – at my expense? (Of course, you get to see how closely related we are, too).

Please reply to me and say “yes.” You don’t even have to put a 🙂 if you don’t want to.

I started this company and this industry over 20 years ago. I predict that you will be happy with the history of YOU that this upgrade will uncover.

Best,

Bennett Greenspan

As you can see, this email can easily be personalized further and adapted to matches at the 37, 25, and 12 marker levels – or even Family Finder matches, now that intermediate-range haplogroups are being reported.

What’s Next?

I’m going back to every one of the kits I sponsored or that represent descendants of one of my ancestors to review their matches again – focusing not just on the closest matches with common surnames, but also on locations – and specifically at lower matching levels. I’ll also be checking their Family Finder matches for male surname matches, or similar surnames.

As is evident from Bennett’s tests, an entire mine of diamonds is out there, just waiting to be unearthed by a Big Y test.

And to think that some people have been advising people to ignore 12-marker matches out-of-hand because they are “entirely irrelevant.” They aren’t – for two reasons.

  1. First, some early testers only tested to that level
  2. Second, because of the deeper history that Big Y tests from those matches will uncover
