Top Ten RootsTech 2022 DNA Sessions + All DNA Session Links

The official dates of RootsTech 2022 were March 3-5, but the sessions and content in the vendor booths are still available. I’ve compiled a list of the sessions focused on DNA, with web links on the RootsTech YouTube channel

YouTube reports the number of views, so I was able to compile that information as of March 8, 2022.

I do want to explain a couple of things to add context to the numbers.

Most speakers recorded their sessions, but a few offered live sessions which were recorded, then posted later for participants to view. However, there have been glitches in that process. While the sessions were anticipated to be available an hour or so later, that didn’t quite happen, and a couple still aren’t posted. I’m sure the presenters are distressed by this, so be sure to watch those when they are up and running.

The Zoom rooms where participants gathered for the live sessions were restricted to 500 attendees. The YouTube number of views does not include the number of live viewers, so you’ll need to add an additional number, up to 500.

When you see a number before the session name, whether recorded or live, that means that the session is part of a series. RootsTech required speakers to divide longer sessions into a series of shorter sessions no longer than 15-20 minutes each. The goal was for viewers to be able to watch the sessions one after the other, as one class, or separately, and still make sense of the content. Let’s just say this was the most challenging thing I’ve ever done as a presenter.

For recorded series sessions, these are posted as 1, 2 and 3, as you can see below with Diahan Southard’s sessions. However, with my live session series, that didn’t happen. It looks like my sessions are a series, but when you watch them, parts 1, 2 and 3 are recorded and presented as one session. Personally, I’m fine with this, because I think the information makes a lot more sense this way. However, it makes comparisons difficult.

This was only the second year for RootsTech to be virtual and the conference is absolutely HUGE, so live and learn. Next year will be smoother and hopefully, at least partially in-person too.

When I “arrived” to present my live session, “Associating Autosomal DNA Segments With Ancestors,” my lovely moderator, Rhett, told me that they were going to livestream my session to the RootsTech page on Facebook as well because they realized that the 500 Zoom seat limit had been a problem the day before with some popular sessions. I have about 9000 views for that session and more than 7,400 of them are on the RootsTech Facebook page – and that was WITHOUT any advance notice or advertising. I know that the Zoom room was full in addition. I felt kind of strange about including my results in the top ten because I had that advantage, but I didn’t know quite how to otherwise count my session. As it turns out, all sessions with more than 1000 views made it into the top ten so mine would have been there one way or another. A big thank you to everyone who watched!

I hope that the RootsTech team notices that the most viewed session is the one that was NOT constrained by the 500-seat limited AND was live-streamed on Facebook. Seems like this might be a great way to increase session views for everyone next year. Hint, hint!!!

I also want to say a huge thank you to all of the presenters for producing outstanding content. The sessions were challenging to find, plus RootsTech is always hectic, even virtually. So, I know a LOT of people will want to view these informative sessions, now that you know where to look and have more time. Please remember to “like” the session on YouTube as a way of thanking your presenter.

With 140 DNA-focused sessions available, you can watch a new session, and put it to use, every other day for the next year! How fun is that! You can use this article as your own playlist.

Please feel free to share this article with your friends and genealogy groups so everyone can learn more about using DNA for genealogy.

Ok, let’s look at the top 10. Drum roll please…

FamilyTreeDNA Keynote, RootsTech Wrap + Special Show Pricing Still Available

Am I ever whipped. My two live Sessions that were actually a series of three classes each took place on Friday. Yes, that means I presented 6 sessions on Friday, complete with a couple of Zoom gremlins, of course. It’s the nature of the time we live in.

RootsTech tried something new that they’ve never done before. The Zoom class sessions were restricted to 500 attendees each. RootsTech was concerned about disappointed attendees when the room was full and they couldn’t get in, so we live-streamed three of my sessions to Facebook in addition to the 500 Zoom seats.

As of this evening, 6,800 of you have viewed the Facebook video, “Associating Autosomal DNA Segments With Ancestors.” I’m stunned, and touched. Thank you, thank you. Here’s the Facebook link, and here’s the RootsTech YouTube link.

My afternoon sessions, “What Can I DO With Ancestral DNA Segments?” can be viewed here at RootsTech or here on YouTube.

I must admit, I’m really, REALLY looking forward to being together again because RootsTech without the socializing and in-person Expo Hall just isn’t the same. Still, be sure to take a virtual walk through the Expo Hall, here. There’s lots of content in the vendors” booths and it will remain available for all of 2022, until the beginning of RootsTech 2023..

Between prep for my classes and presenting, I didn’t have a lot of time to watch other sessions, but I was able to catch the FamilyTreeDNA keynote and their 2022 Product Sneak Peek. Both were quite worthwhile.

However, I just realized that FamilyTreeDNA’s special show pricing promo codes are still valid for the next two days.

 Special Prices Are Still Available

Every single test that FamilyTreeDNA offers, including UPGRADES, is on sale right now by using special RootsTech promo codes. These prices are good for two more days, through March 7th, so if you want to purchase a Y DNA test, mitochondrial, or Family Finder autosomal test, or upgrade, click here to see the prices only available at RootsTech (and to you through my blog.) It’s not too late, but it will be soon.

FamilyTreeDNA’s Keynote

FamilyTreeDNA’s keynote was titled FamilyTreeDNA: 22 Years of Breaking Down Brick Walls.

I really enjoyed this session, in part because I’ve been a part of the genetic genealogy revolution and evolution from the beginning. Not only that, but I know every single person they interviewed for this video, and have for years. If you’ve been participating in genetic genealogy for some time, you’ll know many of these people too. For a minute, it was almost as good as visiting in person.

I’m going to share a few highlights from the session, but I’m also going to include information NOT in the video. I was one of the early project administrators, so I’ve been along for the ride for just a few months shy of 22 years.

FamilyTreeDNA was the first US company to enter the DNA testing space, the first to offer Y DNA testing, and the only one of the early companies that remains viable today. FamilyTreeDNA was the result of Bennett Greenspan’s dream – but initially, he was only dreaming small. Just like any other genealogist – he was dreaming about breaking down a brick wall which he explains in the video.

I’m so VERY grateful that Bennett had that dream, and persisted, because it means that now millions of us can do the same – and will into the future.

Bennett tells this better than anyone else, along with his partner, Max Blankfeld.

“Some people were fascinated,” Bennett said.

Yep, that’s for sure! I certainly was.

“Among the first genetic genealogists in the world.”

“Frontier of the genetic genealogy revolution.”

Indeed, we were and still are. Today’s genetic genealogy industry wouldn’t even exist were it not for FamilyTreeDNA and their early testers.

I love Max Blankfeld’s story of their first office, and you will too.

This IS the quintessential story of entrepreneurship.

In 2004, when FamilyTreeDNA was only four years old, they hosted the very first annual international project administrator’s conference. At that time, it was believed that the only people that would be interested in learning at that level and would attend a DNA conference would be project administrators who were managing surname and regional projects. How times have changed! This week at RootsTech, we probably had more people viewing DNA sessions than people that had tested altogether in 2004. I purchased kit number 30,087 on December 28, 2004, and kit 50,000 a year later on New Year’s Eve right at midnight!

In April 2005, Nat Geo partnered with FamilyTreeDNA and founded the Genographic Project which was scheduled to last for 5 years. They were hoping to attract 100,000 people who would be willing to test their DNA to discover their roots – and along with that – our human roots. The Genographic Project would run for an incredible 15 years.

In 2005 when the second Project Administrator’s conference was held at the National Geographic Society headquarters in Washington DC, I don’t think any of us realized the historic nature of the moment we were participating in.

I remember walking from my hotel, ironically named “Helix,” to that iconic building. I had spent my childhood reading those yellow magazines at school and dreaming of far-away places. As an adult, I had been a life-long subscriber. Never, in my wildest dreams did I imagine ever visiting Nat Geo and walking the marble Explorer’s Hall with the portraits of the founders and early explorers hanging above and keeping a watchful eye on us. We would not disappoint them.

That 100,000 participation goal was quickly reached, within weeks, and surpassed, leading us all to walk the road towards the building that housed the Explorer’s Hall, Explorers’ in Residence, and so much more.

We were all explorers, pioneers, adventurers seeking to use the DNA from our ancestors in the past to identify who they were. Using futuristic technology tools like a mirror to look backward into the dim recesses of the past.

The archaeology being unearthed and studied was no longer at the ends of the earth but within our own bodies. The final frontier. Reaching out to explore meant reaching inward, and backward in time, using the most progressive technology of the day.

Most of the administrators in attendance, all volunteers, were on a first-name basis with each other and also with Max, Bennett, and the scientists.

Here, Bennett with a member of the science team from the University of Arizona describes future research goals. Every year FamilyTreeDNA has improved its products in numerous ways.

Today, that small startup business has its own ground-breaking state-of-the-art lab. More than 10,000 DNA projects are still administered by passionate volunteer administrators who focus on what they seek – such as the history of their surname or a specific haplogroup. Their world-class lab allows FamilyTreeDNA to focus on research and science in addition to DNA processing. The lab allows constant improvement so their three types of genetic genealogy products, Y, mitochondrial and autosomal DNA.

Those three types of tests combine to provide genealogical insights and solutions. The more the science improves, the more solutions can and will be found.

If you watch the video, you’ll see 6 people who have solved particularly difficult and thorny problems. We are all long-time project administrators, all participate on a daily basis in this field and community – and all have an undying love for both genealogy and genetic genealogy.

You’ll recognize most of these people, including yours truly.

  • I talk about my mother’s heritage, unveiled through mitochondrial DNA.
  • Rob Warthen speaks about receiving a random phone call from another genealogist as his introduction to genetic genealogy. Later, he purchased a DNA test for his girlfriend, an adoptee, for Christmas and sweetened the deal by offering to “go where you’re from” for vacation. He didn’t realize why she was moved to tears – that test revealed the first piece of information she had ever known about her history. DNA changed her and Rob’s life. He eventually identified her birth parents – and went on to found both DNAAdoption.org and DNAGedcom.
  • Richard Hill was adopted and began his search in his 30s, but it would be DNA that ended his search. His moving story is told in his book, Finding Family: My Search for Roots and the Secrets in My DNA.
  • Mags Gaulden, professional genealogist and founder of Grandma’s Genes and MitoYDNA.org tells about her 91-year-old adopted client who had given up all hope of discovering her roots. Back in the 1950s, there was literally nothing in her client’s adoption file. She was reconciled to the fact that “I would never know who I was.” Mags simply could not accept that and 2 years later, Mags found her parents’ names.

  • Lara Diamond’s family was decimated during the holocaust. Lara’s family thought everyone in her grandfather’s family had been killed, but in 2013, autosomal DNA testing let her to her grandfather’s aunt who was not killed in the holocaust as everyone thought. The aunt and first cousin were living in Detroit. Lara went from almost no family to a family reunion, shown above. She says she finally met “people who look like me.”
  • Katherine Borges founded ISOGG.org, the International Society of Genetic Genealogy in 2005, following the first genetic genealogy conference in late 2004 where she realized that the genealogy community desperately needed education – beginning with DNA terms. I remember her jokingly standing in the hallway saying that she understood three words, “a, and and the.” While that’s cute today, it was real at that time because DNA was a foreign language, technology, and concept to genealogy. In fact, for years we were banned from discussing the topic on RootsWeb. The consummate genetic genealogist, Katherine carries DNA kits in her purse, even to Scotland!

Bennett says that he’s excited about the future, for the next generation of molecular scientific achievements. It was Bennett that greenlit the Million Mito project. Bennett’s challenge as a genetic genealogy/business owner was to advance the science that led to products while making enough money to be able to continue advancing the science. It was a fine line, but Max and Bennett navigated those waters quite well.

Apparently, Max, Bennett, and the FamilyTreeDNA customers weren’t the only people who believe that.

In January 2021, myDNA acquired and merged with FamilyTreeDNA. Max and Bennett remain involved as board members.

Dr.Lior Rauchberger, CEO of myDNA which includes FamilyTreeDNA

Dr. Lior Rauchberger, the CEO of the merged enterprise believes in the power of genetics, including genetic genealogy, and is continuing to make investments in FamilyTreeDNA products – including new features. There have already been improvements in 2021 and in the presentation by Katy Rowe, the Product Manager for the FamilyTreeDNA products, she explains what is coming this year.

I hope you enjoyed this retrospective on the past 22 years and are looking forward to crossing new frontiers, and breaking down those brick walls, in the coming decades.

Sneak Peek at FamilyTreeDNA – New Features and Upcoming Releases

You can watch Katy Rowe’s Sneak Peek video about what’s coming, here.

Of course, while other companies need to split their focus between traditional genealogy research records and DNA, FamilyTreeDNA does not. Their only focus is genetics. They plan to make advances in every aspect of their products.

FamilyTreeDNA announced a new Help Center which you can access, here. I found lots of short videos and other helpful items. I had no idea it existed.

In 2021, customers began being able to order a combined Family Finder and myDNA test to provide insights into genealogy along with health and wellness

Wellness includes nutrition and fitness insights.

Existing customers either are or will be able to order the myDNA upgrade to their existing test. The ability to upgrade is being rolled out by groups. I haven’t had my turn yet, but when I do, I’ll test and let you know what I think. Trust me, I’m not terribly interested in how many squats I can do anymore, because I already know that number is zero, but I am very interested in nutrition and diet. I’d like to stay healthy enough to research my ancestors for a long time to come.

FamilyTreeDNA announced that over 72,000 men have taken the Big Y test which has resulted in the Y DNA tree of mankind surpassing 50,000 branches.

This is utterly amazing when you consider how far we’ve come since 2002. This also means that a very high number of men, paired with at least one other man, actually form a new branch on the Y haplotree.

The “age” of tester’s Y DNA haplogroups is now often within the 500-year range – clearly genealogical in nature. Furthermore, many leaf-tip haplogroups as defined by the Big Y SNPs are much closer than that and can differentiate between branches of a known family. The Big Y-700 is now the go-to test for Y DNA and genealogy.

Of course, all these new branches necessitate new maps and haplogroup information. These will be released shortly and will provide users with the ability to see the paths together, which is the view you see here, or track individual lines. The same is true for mitochondrial DNA as well.

Y DNA tree branch ages will be forthcoming soon too. I think this is the #1 most requested feature.

On the Mitochondrial DNA side of the house, the Million Mito project has led to a significant rewrite of the MitoTree. As you know, I’m a Million Mito team member.

Here’s Dr. Paul Maier’s branch, for example. You can see that in the current version of the Phylotree, there is one blue branch and lots of “child” branches beneath that. Of course, when we’re measuring the tree from “Eve,” the end tip leaf branches look small, but it’s there that our genealogy resides.

In the new version, yet to be released, there is much more granularity in the branches of U5a2b2a.

To put this another way, in today’s tree, haplogroup U5a2b2a is about 5,000 years old, but the newly defined branches bring the formation of Paul’s (new) haplogroup into the range of about 500 years. Similar in nature to the Y DNA tree and significantly more useful for genealogical purposes. If you have not taken a mitochondrial DNA full sequence test, please order one now. Maybe your DNA will help define a new branch on the tree plus reveal new information about your genealogy.

Stay tuned on this one. You know the Million Mito Project is near and dear to my heart.

2022 will also see much-needed improvements in the tree structure and user experience, as well as the matches pages.

There are a lot of exciting things on FamilyTreeDNA’s plate and I’m excited to see these new features and functions roll out over the next few months.

Just the Beginning

The three days of RootsTech 2022 may be over, but the content isn’t.

In fact, it’s just the beginning of being able to access valuable information at your convenience. The vendor booths will remain in the Expo Hall until RootsTech 2023, so for a full year, plus the individual instructor’s sessions will remain available for three years.

In a few days, after I take a break, I’ll publish a full list of DNA sessions, along with links for your convenience.

Thank You Shout Outs

I want to say a HUGE thank you to RootsTech for hosting the conference and making it free. I specifically want to express my gratitude to the many, many people working diligently behind the scenes during the last year, and frantically during the past three days.

Another huge thank you to the speakers and vendors whose efforts provide the content for the conference.

And special thanks to you for loving genealogy, taking your time to watch and learn, and for reading this blog.

How to Find RootsTech 2022 Sessions + Other Info You Need to Know

Tomorrow, Thursday, March 3rd is the beginning of RootsTech 2022 which is completely free and entirely virtual this year.

You’ll find a bouquet of speakers from around the world providing sessions in many languages. An auto-translate feature is available through YouTube as well.

I hope you’ve already signed up for RootsTech. If not, here are instructions.

The opening presentation by Steve Rockwood will take place on the “Main Stage, here,” at 10 AM EST.

The Expo Hall opens at the same time, and class sessions begin as well.

The navigation bar is at the top of your page.

New Options

Like last year, RootsTech is offering 15-20 minute sessions, with a few sessions being offered as a series which means there are either two, or three, 15-20 minute sessions that are intended to be viewed serially.

Additionally, some presentations, including several of mine, are live this year. Fingers crossed that Zoom doesn’t act up and technology gremlins don’t attend RootsTech too.

Session Availability

Classes, presentations or sessions, however you refer to them, will be offered for three full days and will be available for some time after as well.

How long they will be available depends on the source of the class/session/presentation. If the presentation is given by a vendor, the vendor’s booths and content won’t be available for as long as sessions presented by individuals.

I don’t know how long keynotes will be available either.

I do know that the RootsTech team told the speakers that their intention is for the sessions to remain online for three years unless they are no longer relevant for some reason.

I’ll explain how to find different classes and create a playlist in a minute. There are a few workarounds that will be very beneficial and several places you’ll want to look to be sure you find everything – including the Expo Hall.

Expo Hall

The Expo Hall, meaning vendor booths, organizations, and supporters will also open at 10 AM EST on Thursday, March 3rd and they will remain open through Saturday, March 5th, closing at 7 PM EST. This is the time that the booth is “staffed.” You can of course stop by anytime. The content in each booth may be available for longer and was last year.

Don’t overlook vendor booths thinking you can only find items for sale there. That’s not the case at all. Many if not most vendors and organizations will also have presentations and other resources available for you there too. What better source to find out about that organization’s tools and how to use them successfully than from the horse’s mouth, or booth, in this case.

Speaker’s Bookstore

There will be a Speaker’s Bookstore this year, and no, you cannot purchase a speaker in the store. You can, however, purchase things the speaker might have to sell, like books or services or whatever is relevant to their specialty. The Speaker’s Bookstore will be found in the Expo Hall.

This is a great way to support the speakers, plus, don’t forget to “like” sessions you enjoy.

Sessions

There are several ways to navigate the RootsTech website, and not all types of sessions are in the same place, so I want to be sure you know how to find everything and how to create a playlist for yourself. Furthermore, RootsTech is still trying to iron out some last-minute issues, so I’ve detailed ways I’ve found to deal with challenges.

Please also note that last year’s 2021 sessions are still available as well. Here’s a comprehensive list of 2021 DNA sessions that I created for your convenience, with links to the session recordings.

Live Sessions Calendar

To view all of the live sessions, including several roundtables, in one place, go to the Calendar, here.

You’ll notice that there are three days, and three groups of presentations, with 9 total sets of live sessions for you to choose from. Some sessions are scheduled “very late” in the US, but remember that late here is early someplace else and vice versa. RootsTech has a worldwide audience.

Be sure to review each group and make your selections.

In order to add a session to your playlist, click on the little “+” sign. It’s OK if you select multiple events for the same timeslot. You’ll just have to choose between them later, or watch some as recordings. All live sessions are being recorded. I don’t know how soon they will be available for viewing.

The PlayList can also serve as a “to do” list for after RootsTech as well. Just uncheck the ones you’ve already seen.

I like to watch live sessions because the speakers often provide time-sensitive information. You may also have the opportunity to ask chat questions of live presenters.

Session Search

Let’s say you’re interested in viewing presentations of a specific speaker.

Click to enlarge any image

Click on “Sessions,” and you’ll see the search box. Type the name of the speaker or any keyword into the search box. Be aware that the search/filter function is one of the aspects that the RootsTech team is still diligently working on. We’ll be discussing different ways to find things so you can be positive you’ve found what’s relevant for you.

Session Filters

On the left side, you see a list of filters. You can use these filters alone, in groups, or in conjunction with the search feature.

I suggest viewing each drop down and experimenting a bit, especially combinations.

I typed the word “dna” in the search box, selected the DNA category under Topic, plus selected only 2022 and I see a total of 151 DNA sessions. That’s a smorgasbord!!!!

Adding 2021 for both years shows a total of 278 sessions.

You could add language or other filters as well.

Series Filter

The “Series Episode” filter under “Content Type” isn’t showing all of the sessions that are a series of 2 or 3 contiguous sessions. My series sessions aren’t showing yet (as of this writing,) but some series sessions are. I hope this will be fixed soon.

Doggone Pesky Bugs

The searches and filters aren’t working consistently correctly right now. I only mention this because you may not see everything available for individual speakers, vendors or categories, so try various avenues, meaning search and filter in multiple ways to be sure you’re seeing everything relevant.

Creating a virtual event to serve over a million attendees is a daunting task, and the team really is working hard to resolve issues.

Add to the PlayList

When you add a session to your playlist, the “+” becomes an “X”.

I definitely want to hear what Paul Maier has to say about the Million Mito Project! You can read more about the Million Mito Project here and here.

Using Your PlayList

Your PlayList can be viewed at the top under the menu.

Your sessions will be listed in chronological order, generally with the day and time displayed, but not always. Hmmm…

I noticed that the first session showing, “The Million Mito Project” by Paul Maier doesn’t display a date or time, so I clicked to view the session. It is scheduled for 8 PM on March 2nd, before the conference actually opens, so be sure to check the session times. I’ll check back later today to be sure this is accurate.

I heartily recommend putting this session on your PlayList.

As a Million Mito team member, I might or might or might not be writing a short article soon on this very topic! 😊

Innovators Portal

Take a look at the Innovators Portal where you’ll find several “incognito sessions.”

I haven’t found all of these sessions listed elsewhere, and several are quite interesting.

This is a great place to see what vendors are doing.

Y DNA age estimates – OMG finally! I’m adding this one to my PlayList for sure!!!

You can also view your PlayList by clicking on the little “play” shortcut arrow.

My Sessions

I want to be sure you can find and view my sessions.

I have 4 sessions this year, two of which are actually a series of three sessions each. If you’re counting, yes, that means I’ve created a total of 8 sessions. If you’re thinking, “she’s nuts,” you’d be right. I’ll likely never do this again. It’s just so easy to get inspired, but then the weeks of work comes later.

If you’d like to view my autosomal DNA session from 2021, DNA Triangulation: What, Why and How, click here.

My 2021 session, Revealing Your Mother’s Ancestors and Where They Came From lives in the RootsTech DNA Learning Center, and you can watch it here.

I’m very pleased to offer four sessions in 2022 that I’ve listed in schedule order, below.

DNA for Native American Ancestryclick here to add to PlayList and view.

Thursday, March 3rd – 10 AM EST

I’ll be talking about the contents of DNA for Native American Genealogy, my new book. I wrote this book to help people identify their Native American ancestors, or put those rumors to rest.

There is a myriad of ways to approach this challenge, beginning with your family history, then using several genetic tools. The book covers methodology, geography, ethnicity results, Y DNA, mitochondrial DNA, autosomal DNA, your cousins as gold nuggets, third-party tools, identifying that elusive Native ancestor, and more.

This session is recorded, so you can watch it anytime after the conference opens.

Native American DNA – Ancient and Contemporary Mapsclick here to add to PlayList and view.

Thursday, March 3rd – 2 PM EST LIVE

One of my very favorite parts of writing the book was working with ancient DNA which informs our understanding of where specific groups of people lived, where they migrated – and where their descendants are found today.

Whether you’re interested in Native American heritage, history, anthropology or you’re a map junkie – join me because we are going to have a GREAT time.

Associating Autosomal DNA Segments With Ancestorsclick here to add to PlayList and view.

Friday, March 4th – 10 AM LIVE, Series

This session is a series of three 20-minute sessions that you can view by simply signing in to the first session. Each individual session will have a short Q&A following the session before moving on to the next one. This series will be recorded live so that the individual sessions can be viewed later, either together or separately.

I discuss why segments are important to genealogy, how to find ancestral segments at each major DNA testing vendor, plus GEDmatch, and identifying which ancestor(s) those segments descend from. You might be surprised to learn that I utilize Ancestry in this process too, even though they don’t have a chromosome browser.

After figuring out how to associate your DNA segments with specific ancestors, there’s so much more you can do! I hope you’ll join me for this next session too!

What Can I DO With Ancestral DNA Segments?click here to add to PlayList and view.

Friday March 4th – 2 PM LIVE, Series

This session is a series of three 20-minute sessions that you can view by simply signing in to the first session. Each session will have a short Q&A following the session before moving on to the next one. This live series will be recorded so that the individual sessions can be viewed later, either together or separately.

In this series, I review the more advanced tools at the DNA testing vendors, plus third-party tools like Genetic Affairs, DNAPainter and GEDmatch.

The great thing is that this painter’s pallet of tools has automated what we had been doing manually for several years – and every vendor and tool has something unique to offer genealogists.

Your Turn

Now it’s time to create your PlayList of sessions and make your RootsTech viewing plan. Hope to “see” you there!

Identify Your Ancestors – Follow Nested Ancestral Segments

I don’t think that we actively think about our DNA segments as nested ancestors, like Russian Matryoshka dolls, but they are.

That’s exactly why segment information is critical for genealogists. Every segment, and every portion of a segment, has an incredibly important history. In fact, you could say that the further back in time we can track a segment, the more important it becomes.

Let’s see how to unveil nested segments. I’ll use my chromosome 20 as an example because it’s a smaller chromosome. But first, let’s start with my pedigree chart.

Pedigree

Click images to enlarge.

Before we talk about nested segments that originated with specific ancestors, it’s important to take a look at the closest portion of my maternal pedigree chart. My DNA segments came from and through these people. I’ll be working with the first 5 generations, beginning with my mother as generation #1.

Generation 1 – Parents

In the first generation, we receive a copy of each chromosome from each parent. I have a copy of chromosome 20 from my mother and a copy from my father.

At FamilyTreeDNA, you can see that I match my mother on the entire tested region of each chromosome.

Therefore, the entire length of each of my chromosomes is assigned to both mother and father because I received a copy from each parent. I’m fortunate that my mother’s DNA was able to be tested before she passed away.

We see that each copy of chromosome 20 is a total of 110.20 cM long with 17,695 SNPs.

Of course, my mother inherited the DNA on her chromosome 20 from multiple ancestors whose DNA combined in her parents, a portion of which was inherited by my mother. Mom received one chromosome from each of her parents.

I inherited only one copy of each chromosome (In this case, chromosome 20) from Mom, so the DNA of her two parents was divided and recombined so that I inherited a portion of my maternal chromosome 20 from both of my maternal grandparents.

Identifying Maternal and Paternal Matches

Associating matches with your maternal or paternal side is easy at FamilyTreeDNA because their Family Finder matching does it automatically for you if you upload (or create) a tree and link matches that you can identify to their proper place in your tree.

FamilyTreeDNA then uses that matching segment information from known, identified relatives in your tree to place people who match you both on at least one significant-sized segment in the correct maternal, paternal, (or both) buckets. That’s triangulation, and it happens automatically. All you have to do is click on the Maternal tab to view your triangulated maternal matches. As you can see, I have 1432 matches identified as maternal. 

Some other DNA testing companies and third-party tools provide segment information and various types of triangulation information, but they aren’t automated for your entire match list like Family Finder matching at FamilyTreeDNA.

You can read about triangulation in action at MyHeritage, here, 23andMe, here, GEDmatch, here, and DNAPainter, which we’ll use, here. Genetic Affairs AutoKinship tool incorporates triangulation, as does their AutoSegment Triangulation Cluster Tool at GEDmatch. I’ve compiled a reference resource for triangulation, here.

Every DNA testing vendor has people in their database that haven’t tested anyplace else. Your best strategy for finding nested segments and identifying matches to specific ancestors is to test at or transfer your DNA file to every vendor plus GEDmatch where people who test at Ancestry sometimes upload for matching. Ancestry does not provide segment information or a chromosome browser so you’ll sometimes find Ancestry testers have uploaded to GEDmatch, FamilyTreeDNA  or MyHeritage where segment information is readily available. I’ve created step-by-step download/upload instructions for all vendors, here.

Generation 2 – Grandparents

In the second generation, meaning that of my grandparents, I inherited portions of my maternal and paternal grandmother’s and grandfather’s chromosomes.

My maternal and paternal chromosomes can be divided into two pieces or groups each, one for each grandparent.

Using DNAPainter, we can see my father’s chromosome 20 on top and my mother’s on the bottom. I have previously identified segments assigned to specific ancestors which are represented by different colors on these chromosomes. You can read more about how to use DNAPainter, here.

We can divide the DNA inherited from each parent into the DNA inherited from each grandparent based on the trees of people we match. If we test cousins from each side, assigning segments maternally or paternally becomes much, much easier. That’s exactly why I’ve tested several.

For the rest of this article, I’m focusing only on my mother’s side because the concepts and methods are the same regardless of whether you’re working on your maternal side or your paternal side.

Using DNAPainter, I expanded my mother’s chromosome 20 in order to see all of the people I’ve painted on my mother’s side.

DNAPainter allows us to paint matching segments from multiple testing vendors and assign them to specific ancestors as we identify common ancestors with our matches.

Based on these matches, I’ve divided these maternal matches into two categories:

  • Maternal grandmother, meaning my mother’s mother, bracketed in red boxes
  • Maternal grandfather, meaning my mother’s father, bracketed in black boxes.

The text and arrows in these graphics refer to the colors of the brackets/boxes, and NOT the colors of the segments beside people’s names. For example, if you look at the large black box at far right, you’ll see several people, with their matching segments identified by multiple colored bars. The different colored segments (bars) mean I’ve associated the match with different ancestors in multiple or various levels of generations.

Generation 3 – Great-grandparents

Within those maternal and paternal grandparent segments, more nested information is available.

The black Ferverda grandfather segments are further divided into black, from Hiram Ferverda, and gold from his wife Eva Miller. The same concept applies to the red grandmother segments which are now divided into red representing Nora Kirsch and purple representing Curtis Lore, her husband.

While I have only been able to assign the first four segments (at the top) to one person/ancestor, there’s an entire group of matches who share the grouping of segments at right, in gold, descended through Eva Miller. The Miller line is Brethren and Mennonite with lots of testers, so this is a common pattern in my DNA matches.

Eva Miller, the gold ancestor, has two parents, Margaret Elizabeth Lentz and John David Miller, so her segments would come from those two sides.

Generation 4 and 5 – Fuschia Segment

I was able to track the segment shown in fuschia indicated by the blue arrow to Jacob Lentz and his wife Fredericka Ruhle, German immigrant ancestors. Other people in this same match (triangulation) group descend from Margaret Elizabeth Lentz and John David Miller – but that fuschia match is the one that shows us where that segment originated. This allows us to assign that entire gold/blue bracketed set of segments to a specific ancestor or ancestral couple because they triangulate, meaning they all match me and each other.

Therefore, all of the segments that match with the fuschia segment also track back to Jacob Lentz and Fredericka Ruhle, or to their ancestors. We would need people who descend from Jacob’s parents and/or Fredericka’s parents to determine the origins of that segment.

In other words, we know all of these people share a common source of that segment, even if we don’t yet know exactly who that common ancestor was or when they lived. That’s what the process of tracking back discovers.

To be very clear, I received that segment through Jacob and Fredericka, but some of those matches who I have not been able to associate with either Jacob or Fredericka may descend from either Jacob or Fredericka’s ancestors, not Jacob and Fredericka themselves. Connecting the dots between Jacob/Fredericka and their ancestors may be enlightening as to the even older source of that segment.

Let’s take a look at nested segments on my pedigree chart.

Nested Pedigree

Click to enlarge.

You can see the progression of nesting on my pedigree chart, using the same colors for the brackets/boxes. The black Ferverda box at the grandparent level encompasses the entire paternal side of my mother’s ancestry, and the red includes her mother’s entire side. This is identical to the DNAPainter graphic, just expressed on my pedigree chart instead of my chromosome 20.

Then the black gets broken into smaller nested segments of black, gold and fuschia, while the red gets broken into red and purple.

If I had more matches that could be assigned to ancestors, I would have even more nested levels. Of course, if I was using all of my chromosomes, not just 20, I would be able to go back further as well.

You can see that as we move further back in time, the bracketed areas assigned to each color become smaller and smaller, as do the actual segments as viewed on my DNAPainter chromosomes.

Segments Get Progressively Smaller

You can see in the pedigree chart and segment painting above that the segments we inherit from specific ancestors divide over time. As we move further and further back in our tree, the segments inherited from any specific ancestor get smaller and smaller too.

Dr. Paul Maier in the MyOrigins 3.0 White Paper provides this informative graphic that shows the reduction in segments and the number of ancestors whose DNA we carry reaching back in time.

I refer to this as a porcupine chart.

Eventually, we inherit no segments from red ancestors, and the pieces of DNA that we inherit from the distant blue ancestors become so small and fragmented that they cannot be positively identified as coming from a specific ancestor when compared to and matched with other people. That’s why vendors don’t show small segment matches, although different vendors utilize different segment thresholds.

The debate about how small is too small continues, but the answer is not simply segment size alone. There is no one-size-fits-all answer.

As segments become smaller, the probability, or chances that we match another person by chance (IBC) increases. Proof that someone shares a specific ancestor, especially when dealing with increasingly smaller segments is a function of multiple factors, such as tree completeness for both people, shared matches, parental match confirmation, and more. I wrote about What Constitutes Proof, here.

In the Family Finder Matching White Paper, Dr. Maier provides this chart reflecting IBD (Identical By Descent) and IBC (Identical By Chance) segments and the associated false positivity rate. That means how likely you are to match someone on a segment of that size by chance and NOT because you both share the DNA from a common ancestor.

I wrote Concepts: Identical by Descent, State, Population and Chance to help you better understand how this works.

In the chart below, I’ve combined the generations, relationships, # of ancestors, assuming no duplicates, birth year range based on an approximate 30-year generation, percent of DNA assuming exactly half of each ancestor’s DNA descends in each generation (which we know isn’t exactly accurate), and the average amount of total inherited cMs using that same assumption.

Note that beginning with the 7th generation, on average, we can expect to inherit less than 1% of the DNA of an ancestor, or approximately 55 total cM which may be inherited in multiple segments.

The amount of actual cMs inherited in each generation can vary widely and explains why, beginning with third cousins, some people won’t share DNA from a common ancestor above the various vendor matching thresholds. Yet, other cousins several generations removed will match. Inheritance is random.

Parallel Inheritance

In order to match someone else descended from that 11th generation ancestor, BOTH you AND your match will need to have inherited the exact SAME DNA segment, across 11 generations EACH in order to match. This means that 11 transmission events for each person will need to have taken place in parallel with that identical segment being passed from parent to child in each line. For 22 rolls of the genetic dice in a row, the same segment gets selected to be passed on.

You can see why we all need to work to prove that distant matches are valid.

The further back in time we work, the more factors we must take into consideration, and the more confirming proof is needed that a match with another individual is a result of a shared ancestor.

Having said that, shared distant matches ARE the key to breaking through brick-wall ancestors. We just need to be sure we are chasing the real deal and not a red herring.

Exciting Possibilities

The most exciting possibility is that some segments are actually passed intact for several generations, meaning those segments don’t divide into segments too small for matching.

For example, the 22 cM fuschia segment that tracks through generations 4 and 5 to Jacob Lentz and Fredericka Ruhle has been passed either intact or nearly intact to all of those people who stack up and match each other and me on that segment. 22 cM is definitely NOT a small segment and we know that it descended from either Jacob or Fredericka, or perhaps combined segments from each. In any case, if someone from the Lentz line in Germany tested and matched me on that segment (and by inference, the rest of these people too), we would know that segment descended to me from Jacob Lentz – or at least the part we match on if we don’t match on the entire segment.

This is exactly what nested segments are…breadcrumbs to ancestors.

Part of that 22cM segment could be descended from Jacob and part from Fredericka. Then of Jacob’s portion, for example, pieces could descend from both his mother and father.

This is why we track individual segments back in time to discern their origin.

The Promise of the Future

The promise of the future is when a group of other people triangulate on a reasonably sized segment AND know where it came from. When we match that triangulation group, their identified segment may well help break down our brick walls because we match all of them on that same segment.

It is exactly this technique that has helped me identify a Womack segment on my paternal line. I still haven’t identified our common ancestor, but I have confirmed that the Womacks and my Moore/Rice family interacted as neighbors 8 generations ago and likely settled together in Amelia county, migrating from eastern Virginia. In time, perhaps I’ll be able to identify the common Womack ancestor and the link into either my Moore or Rice lines.

I’m hoping for a similar breakthrough on my mother’s side for Philip Jacob Miller’s wife, Magdalena, 7 generations back in my tree. We know Magdalena was Brethren and where they lived when they took up housekeeping. We don’t know who her parents were. However, there are thousands of Miller descendants, so it’s possible that eventually, we will be able to break down that brick wall by using nested segments – ours and people who descend from Magdalena’s siblings, aunts, and uncles.

Whoever those people were, at least some of their descendants will likely match me and/or my cousins on at least one nested Miller segment that will be the same segment identified to their ancestors.

Genealogy is a team sport and solving puzzles using nested segments requires that someone out there is working on identifying triangulated segments that track to their common ancestors – which will be my ancestors too. I have my fingers crossed that someone is working on that triangulation group and I find them or they find me. Of course, I’m working to triangulate and identify my segments to specific ancestors – hoping for a meeting in the middle – that much-desired bridge to the past.

By the time you’ve run out of other records, nested segments are your last chance to identify those elusive ancestors. 

Do you have genealogical brick walls that nested segments could solve?

2021 Favorite Articles

It’s that time of the year again when we welcome the next year.

2021 was markedly different than anything that came before. (Is that ever an understatement!)

Maybe you had more time for genealogy and spent time researching!

So, what did we read in 2021? Which of my blog articles were the most popular?

In reverse order, beginning with number 10, we have:

This timeless article published in 2015 explains how to calculate the amount of any specific heritage you carry based on your ancestors.

Just something fun that’s like your regular pedigree chart, except color coded locations instead of ancestors. Here’s mine

The Autosegment Triangulation Cluster Tool is a brand new tool introduced in October 2021. Created by Genetic Affairs for GEDmatch, this tool combines autoclusters and triangulation.

Many people don’t realize that we actually don’t inherit exactly 25% of our DNA from each grandparent, nor why.

This enlightening article co-authored with statistician Philip Gammon explains how this works, and why it affects all of your matches.

Who doesn’t love learning about ancient DNA and the messages it conveys. Does your Y or mitochondrial DNA match any of these burials? Take a look. You might be surprised.

How can you tell if you are full or half siblings with another person? You might think this is a really straightforward question with an easy answer, but it isn’t. And trust me, if you EVER find yourself in a position of needing to know, you really need to know urgently.

Using simple match, it’s easy to figure how much of your ancestor’s DNA you “should” have, but that’s now how inheritance actually works. This article explains why and shows different inheritance scenarios.

That 28 day timer has expired, but the article can still be useful in terms of educating yourself. This should also be read in conjunction with Ancestry Retreats, by Judy Russell.

If I had a dollar for every time I’ve heard someone say that their ethnicity percentages were “wrong,” I’d be a rich woman, living in a villa in sun-drenched Tuscany😊

This extremely popular article has either been first or second every year since it was published. Ethnicity is both exciting and perplexing.

As genealogists, the first thing we need to do is to calculate what, according to our genealogy, we would expect those percentages to be. Of course, we also need to factor in the fact that we don’t inherit exactly the same amount of DNA from each grandparent. I explain how I calculated my “expected” percentages of ethnicity based on my known tree. That’s the best place to start.

Please note that I am no longer updating the vendor comparison charts in the article. Some vendors no longer release updates to the entire database at the same time, and some “tweak” results periodically without making an announcement. You’ll need to compare your own results at the different vendors at the same point in time to avoid comparing apples and oranges.

The #1 Article for 2021 is…

  1. Proving Native American Ancestry Using DNA

This article has either been first (7 times) or second (twice) for 9 years running. Now you know why I chose this topic for my new book, DNA for Native American Genealogy.

If you’re searching for your Native American ancestry, I’ve provided step-by-step instructions, both with and without some percentage of Native showing in your autosomal DNA percentages.

Make 2022 a Great Year!

Here’s wishing you the best in 2022. I hope your brick walls cave. What are you doing to help that along? Do you have a strategy in mind?

Register for RootsTech 2022 Now – It’s Free!

Just the good news we need to end the year. RootsTech 2022, sponsored by FamilySearch, is entirely virtual and completely free – again.

In 2021, over a million people “attended” RootsTech and you can be one of those lucky people in March 2022 too.

In 2022, there will be more than 1500 sessions presented by hundreds of speakers from around the globe in many languages. Of course, that’s in addition to the vendor Expo booths, which I love, and the DNA Basics Learning Center.

The 2022 sessions and speakers aren’t listed yet, but this would be a good time to view any of the 2021 sessions that you never got a chance to. What better thing could you be doing for New Year’s Eve😊

Sign Up!

You can sign up for RootsTech 2022 here, for free.

I’ll let you know as soon as the 2022 sessions are added. The sessions showing are the 2021 classes which RootsTech has graciously made available for the entire year. I don’t know how long they will be viewable, so if you want to watch, please do so now.

As you might imagine, the 2022 speakers are busily (should I say crazily) designing and recording their content. You’ll be seeing me in both recorded sessions (about my new book, DNA for Native American Genealogy,) sharing success-story testimonials, and in several live sessions too.

Yes, some sessions will be live this time and the live sessions will be recorded for later playback. I like to interact with people, so I’ve decided to cross my fingers that the internet gremlins don’t visit me those days! I have seven exciting sessions under construction.

Be sure to test your Y, mitochondrial and autosomal DNA and upload your autosomal DNA to multiple locations in advance so you are prepared to benefit from all of the DNA track presentations and a multitude of wonderful speakers. There’s still time today and tomorrow to take advantage of end-of-the year sales.

FamilyTreeDNA Relaunch – New Feature Overview

The brand-new FamilyTreeDNA website is live!

I’m very pleased with the investment that FamilyTreeDNA has made in their genealogy platform and tools. This isn’t just a redesign, it’s more of a relaunch.

I spoke with Dr. Lior Rauchberger, CEO of myDNA, the parent company of FamilyTreeDNA briefly yesterday. He’s excited too and said:

“The new features and enhancements we are releasing in July are the first round of updates in our exciting product roadmap. FamilyTreeDNA will continue to invest heavily in the advancement of genetic genealogy.”

In other words, this is just the beginning.

In case you were wondering, all those features everyone asked for – Lior listened.

Lior said earlier in 2021 that he was going to do exactly this and he’s proven true to his word, with this release coming just half a year after he took the helm. Obviously, he hit the ground running.

A few months ago, Lior said that his initial FamilyTreeDNA focus was going to be on infrastructure, stability, and focusing on the customer experience. In other words, creating a foundation to build on.

The new features, improvements, and changes are massive and certainly welcome.

I’ll be covering the new features in a series of articles, but in this introductory article, I’m providing an overview so you can use it as a guide to understand and navigate this new release.

Change is Challenging

I need to say something here.

Change is hard. In fact, change is the most difficult challenge for humans. We want improvements, yet we hate it when the furniture is rearranged in our “room.” However, we can’t have one without the other.

So, take a deep breath, and let’s view this as a great new adventure. These changes and tools will provide us with a new foundation and new clues. Think of this as finding long-lost documents in an archive about your ancestors. If someone told me that there is a potential for discovering the surname of one of my elusive female ancestors in an undiscovered chest in a remote library, trust me, I’d be all over it – regardless of where it was or how much effort I had to expend to get there. In this case, I can sit right here in front of my computer and dig for treasure.

We just need to learn to navigate the new landscape in a virtual room. What a gift!

Let’s start with the first thing you’ll see – the main page when you sign in.

Redesigned Main Page

The FamilyTreeDNA main page has changed. To begin with, the text is darker and the font is larger across the entire platform. OMG, thank you!!!

The main page has been flipped left to right, with results on the left now. Projects, surveys, and other information, along with haplogroup badges are on the right. Have you answered any surveys? I don’t think I even noticed them before. (My bad!)

Click any image to enlarge.

The top tabs have changed too. The words myTree and myProjects are now gone, and descriptive tabs have replaced those. The only “my” thing remaining is myOrigins. This change surprises me with myDNA being the owner.

The Results & Tools tab at the top shows the product dropdowns.

The most popular tabs are shown individually under each product, with additional features being grouped under “See More.”

Every product now has a “See More” link where less frequently used widgets will be found, including the raw data downloads. This is the Y DNA “See More” dropdown by way of example.

You can see the green Updated badge on the Family Finder Matches tab. I don’t know if that badge will always appear when customers have new matches, or if it’s signaling that all customers have updated Family Finder Matches now.

We’ll talk about matches in the Family Finder section.

The Family Finder “See More” tab includes the Matrix, ancientOrigins, and the raw data file download.

The mitochondrial DNA section, titled Maternal Line Ancestry, mtDNA Results and Tools includes several widgets grouped under the “See More” tab.

Additional Tests and Tools

The Additional Tests and Tools area includes a link to your Family Tree (please do upload or create one,) Public Haplotrees, and Advanced Matches.

Public haplotrees are free-to-the-public Y and mitochondrial DNA trees that include locations. They are also easily available to FamilyTreeDNA customers here.

Please note that you access both types of trees from one location after clicking the Public Haplotrees page. The tree defaults to Y-DNA, but just click on mtDNA to view mitochondrial haplogroups and locations. Both trees are great resources because they show the location flags of the earliest known ancestors of the testers within each haplogroup.

Advanced Matches used to be available from the menu within each test type, but since advanced matching includes all three types of tests, it’s now located under the Additional Tests and Tools banner. Don’t forget about Advanced Matches – it’s really quite useful to determine if someone matches you on multiple types of tests and/or within specific projects.

Hey, look – I found a tooltip. Just mouse over the text and tabs on various pages to see where tooltips have been added.

Help and Help Center

The new Help Center is debuting in this release. The former Learning Center is transitioning to the Help Center with new, updated content.

Here’s an example of the new easy-to-navigate format. There’s a search function too.

Each individual page, test type, and section on your personal home page has a “Helpful Information” button.

On the main page, at the top right, you’ll see a new Help button.

Did you see that Submit Feedback link?

If you click on the Help Center, you’ll be greeted with context-sensitive help.

I clicked through from the dashboard, so that’s what I’m seeing. However, other available topics are shown at left.

I clicked on both of the links shown and the content has been updated with the new layout and features. No wonder they launched a new Help Center!

Account Settings

Account settings are still found in the same place, and those pages don’t appear to have changed. However, please keep in mind that some settings make take up to 24 hours to take effect.

Family Finder Rematching

Before we look at what has changed on your Family Finder pages, let’s talk about what happened behind the scenes.

FamilyTreeDNA has been offering the Family Finder test for 11 years, one of two very early companies to enter that marketspace. We’ve learned so much since then, not only about DNA itself, but about genetic genealogy, matching, triangulation, population genetics, how to use these tools, and more.

In order to make improvements, FamilyTreeDNA changing the match criteria which necessitated rematching everyone to everyone else.

If you have a technology background of any type, you’ll immediately realize that this is a massive, expensive undertaking requiring vast computational resources. Not only that, but the rematching has to be done in tandem with new kits coming in, coordinated for all customers, and rolled out at once. Based on new matches and features, the user interface needed to be changed too, at the same time.

Sounds like a huge headache, right?

Why would a company ever decide to undertake that, especially when there is no revenue for doing so? The answer is to make functionality and accuracy better for their customers. Think of this as a new bedrock foundation for the future.

FamilyTreeDNA has made computational changes and implemented several features that require rematching:

  • Improved matching accuracy, in particular for people in highly endogamous populations. People in this category have thousands of matches that occur simply because they share multiple distant ancestors from within the same population. That combination of multiple common ancestors makes their current match relationships appear to be closer in time than they are. In order to change matching algorithms, FamilyTreeDNA had to rewrite their matching software and then run matching all over to enable everyone to receive new, updated match results.
  • FamilyTreeDNA has removed segments below 6 cM following sustained feedback from the genealogical community.
  • X matching has changed as well and no longer includes anyone as an X match below 6 cM.
  • Family Matching, meaning paternal, maternal and both “bucketing” uses triangulation behind the scenes. That code also had to be updated.
  • Older transfer kits used to receive only closer matches because imputation was not in place when the original transfer/upload took place. All older kits have been imputed now and matched with the entire database, which is part of why you may have more matches.
  • Relationship range calculations have changed, based on the removal of microsegments, new matching methodology and rematching results.
  • FamilyTreeDNA moved to hg37, known as Build 37 of the human genome. In layman’s terms, as scientists learn about our DNA, the human map of DNA changes and shifts slightly. The boundary lines change somewhat. Versions are standardized so all researchers can use the same base map or yardstick. In some cases, early genetic genealogy implementers are penalized because they will eventually have to rematch their entire database when they upgrade to a new build version, while vendors who came to the party later won’t have to bear that internal expense.

As you can see, almost every aspect of matching has changed, so everyone was rematched against the entire database. You’ll see new results. Some matches may be gone, especially distant matches or if you’re a member of an endogamous population.

You’ll likely have new matches due to older transfer kits being imputed to full compatibility. Your matches should be more accurate too, which makes everyone happy.

I understand a white paper is being written that will provide more information about the new matching algorithms.

Ok, now let’s check out the new Family Finder Matches page.

Family Finder Matches

FamilyTreeDNA didn’t just rearrange the furniture – there’s a LOT of new content.

First, a note. You’ll see “Family Finder” in some places, and “Autosomal DNA” in other places. That’s one and the same at FamilyTreeDNA. The Family Finder test is their autosomal test, named separately because they also have Y DNA and mitochondrial DNA tests.

When you click on Family Finder matches for the first time, you will assuredly notice one thing and will probably notice a second.

First, you’ll see a little tour that explains how to use the various new tools.

Secondly, you will probably see the “Generating Matches” notice for a few seconds to a few minutes while your match list is generated, especially if the site is busy because lots of people are signing on. I saw this message for maybe a minute or two before my match list filled.

This should be a slight delay, but with so many people signing in right now, my second kit took longer. If you receive a message that says you have no matches, just refresh your page. If you had matches before, you DO have matches now.

While working with the new interface this morning, I’ve found that refreshing the screen is the key to solving issues.

My kits that have a few thousand matches loaded Family Matching (bucketing) immediately, but this (Jewish) kit that has around 30,000 matches received this informational message instead. FamilyTreeDNA has removed the little spinning icon. If you mouse over the information, you’ll see the following message:

This isn’t a time estimate. Everyone receives the same message. The message didn’t even last long enough for me to get a screenshot on the first kit that received this message. The results completed within a minute or so. The Family Matching buckets will load as soon as the parental matching is ready.

These delays should only happen the first time, or if someone has a lot of matches that they haven’t yet viewed. Once you’ve signed in, your matches are cached, a technique that improves performance, so the loading should be speedy, or at least speedier, during the second and subsequent visits.

Of course, right now, all customers have an updated match list, so there’s something new for everyone.

Getting Help

Want to see that tutorial again?

Click on that little Help box in the upper right-hand corner. You can view the Tutorial, look at Quick References that explain what’s on this page, visit the Help Center or Submit Feedback.

Two Family Finder Matches Views – Detail and Table

The first thing you’ll notice is that there are two views – Detail View and Table View. The default is Detail View.

Take a minute to get used to the new page.

Detail View – Filter Matches by Match Type

I was pleased to see new filter buttons, located in several places on the page.

The Matches filter at left allows you to display only specific relationship levels, including X-Matches which can be important in narrowing matches to a specific subset of ancestors.

You can display only matches that fall within certain relationship ranges. Note the new “Remote Relative” that was previously called speculative.

Parental Matching and Filtering by Test Type or Trees

All of your matches are displayed by default, of course, but you can click on Paternal, Maternal or Both, like before to view only matches in those buckets. In order for the Family Matching bucketing feature to be enabled, you must attach known relatives’ DNA matches to their proper place in your tree.

Please note that I needed to refresh the page a couple of times to get my parental matches to load the first time. I refreshed a couple of times to be sure that all of my bucketed matches loaded. This should be a first-time loading blip.

There’s a new filter button to the right of the bucketing tabs.

You can now filter by who has trees and who has taken which kinds of tests.

You can apply multiple filters at the same time to further narrow your matches.

Important – Clearing Filters

It’s easy to forget you have a filter enabled. This section is important, in part because Clear Filter is difficult to find.

The clear filter button does NOT appear until you’ve selected a filter. However, after applying that filter, to clear it and RESET THE MATCHES to unfiltered, you need to click on the “Clear Filter” button which is located at the top of the filter selections, and then click “Apply” at the bottom of the menu. I looked for “clear filter” forever before finding it here.

You’re welcome😊

Enhanced Search

Thank goodness, the search functionality has been enhanced and simplified too. Full name search works, both here and on the Y DNA search page.

If you type in a surname without selecting any search filters, you’ll receive a list of anyone with that word in their name, or in their list of ancestral surnames. This does NOT include surnames in their tree if they have not added those surnames to their list of ancestral surnames.

Notice that your number of total matches and bucketed people will change based on the results of this search and any filters you have applied.

I entered Estes in the search box, with no filters. You can see that I have a total of 46 matches that contain Estes in one way or another, and how they are bucketed.

Estes is my birth surname. I noticed that three people with Estes in their information are bucketed maternally. This is the perfect example of why you can’t assume a genetic relationship based on only a surname. Those three people’s DNA matches me on my mother’s side. And yes, I confirmed that they matched my mother too on that same segment or segments.

Search Filters

You can also filter by haplogroup. This is very specific. If you select mitochondrial haplogroup J, you will only receive Family Finder matches that have haplogroup J, NOT J1 or J1c or J plus anything.

If you’re looking for your own haplogroup, you’ll need to type your full haplogroup in the search box and select mtDNA Haplogroup in the search filter dropdown.

Resetting Search Results

To dismiss search results, click on the little X. It’s easy to forget that you have initiated a search, so I need to remember to dismiss searches after I’m finished with each one.

Export Matches

The “Export CSV” button either downloads your entire match list, or the list of filtered matches currently selected. This is not your segment information, but a list of matches and related information such as which side they are bucketed on, if any, notes you’ve made, and more.

Your segment information is available for download on the chromosome browser.

Sort By

The Sort By button facilitates sorting your matches versus filtering your matches. Filters ONLY display the items requested, while sorts display all of the items requested, sorting them in a particular manner.

You can sort in any number of ways. The default is Relationship Range followed by Shared DNA.

Your Matches – Detail View

A lot has changed, but after you get used to the new interface, it makes more sense and there are a lot more options available which means increased flexibility. Remember, you can click to enlarge any of these images.

To begin with, you can see the haplogroups of your matches if they have taken a Y or mitochondrial DNA test. If you match someone, you’ll see a little check in the haplogroup box. I’m not clear whether this means you’re a haplogroup match or that person is on your match list.

To select people to compare in the chromosome browser, you simply check the little square box to the left of their photo and the chromosome browser box pops up at the bottom of the page. We’ll review the chromosome browser in a minute.

The new Relationship Range prediction is displayed, based on new calculations with segments below 6 cM removed. The linked relationship is displayed below the range.

A linked relationship occurs when you link that person to their proper place in your tree. If you have no linked relationship, you’ll see a link to “assign relationship” which takes you to your tree to link this person if you know how you are related.

The segments below 6 cM are gone from the Shared DNA total and X matches are only shown if they are 6 cM or above.

In Common With and Not In Common With

In Common With and Not In Common With is the little two-person icon at the right.

Just click on the little person icon, then select “In Common With” to view your shared matches between you, that match, and other people. The person you are viewing matches in common with is highlighted at the top of the page, with your common matches below.

You can stack filters now. In this example, I selected my cousin, Don, to see our common matches. I added the search filter of the surname Ferverda, my mother’s maiden name. She is deceased and I manage her kit. You can see that my cousin Don and I have 5 total common matches – four maternal and one both, meaning one person matches me on both my maternal and paternal lines.

It’s great news that now Cousin Don pops up in the chromosome browser box at the bottom, enabling easy confusion-free chromosome segment comparisons directly from the In Common With match page. I love this!!!.

All I have to do now is click on other people and then on Compare Relationship which pushes these matches through to the chromosome browser. This is SOOOO convenient.

You’ll see a new tree icon at right on each match. A dark tree means there’s content and a light tree means this person does not have a tree. Remember, you can filter by trees with content using the filter button beside “Both”.

Your notes are shown at far right. Any person with a note is dark grey and no note is white.

If you’re looking for the email contact information, click on your match’s name to view their placard which also includes more detailed ancestral surname information.

Family Finder – Table View

The table view is very similar to the Detail View. The layout is a bit different with more matches visible in the same space.

This view has lots of tooltips on the column heading bar! Tooltips are great for everyone, but especially for people just beginning to find their way in the genetic genealogy world.

I’ll have to experiment a bit to figure out which view I prefer. I’d like to be able to set my own default for whichever view I want as my default. In fact, I think I’ll submit that in the “Submit Feedback” link. For every suggestion, I’m going to find something really positive to say. This was an immense overhaul.

Chromosome Browser

Let’s look at the chromosome Browser.

You can arrive at the Chromosome Browser by selecting people on your match page, or by selecting the Chromosome Browser under the Results and Tools link.

Everything is pretty much the same on the chromosome browser, except the default view is now 6 cM and the smaller segments are gone. You can also choose to view only segments above 10 cM.

If you have people selected in the chromosome browser and click on Download Segments in the upper right-hand corner, it downloads the segments of only the people currently selected.

You can “Clear All” and then click on Download All Segments which downloads your entire segment file. To download all segments, you need to have no people selected for comparison.

The contents of this file are greatly reduced as it now contains only the segments 6 cM and above.

Family Tree

No, the family tree has not changed, and yes, it needs to, desperately. Trust me, the management team is aware and I suspect one of the improvements, hopefully sooner than later, will be an improved tree experience.

Y DNA

The Y DNA page has received an update too, adding both a Detail View and a Table View with the same basic functionality as the Family Finder matching above. If you are reading this article for Y DNA only, please read the Family Finder section to understand the new layout and features.

Like previously, the match comparison begins at the 111 marker level.

However, there’s a BIG difference. If there are no matches at this level, YOU NEED TO CLICK THE NEXT TAB. You can easily see that this person has matches at the 67 level and below, but the system no longer “counts down” through the various levels until it either finds a level with a match or reaches 12 markers.

If you’re used to the old interface, it’s easy to think you’re at the final destination of 12 markers with no matches when you’re still at 111.

Y DNA Detail View

The Y-DNA Detail and Table views features are the same as Family Finder and are described in that section.

The new format is quite different. One improvement is that the Paternal Country of Origin is now displayed, along with a flag. How cool is that!

The Paternal Earliest Known Ancestor and Match Date are at far right. Note that match dates have been reset to the rerun date. At this point, FamilyTreeDNA is evaluating the possibility of restoring the original match date. Regardless, you’ll be able to filter for match dates when new matches arrive.

Please check to be sure you have your Country of Origin, Earliest Known Ancestor, and mapped location completed and up to date.

Earliest Known Ancestor

If you haven’t completed your Earliest Known Ancestor (EKA) information, now’s the perfect time. It’s easy, so let’s do it before you forget.

Click on the Account Settings gear beneath your name in the right-hand upper corner. Click on Genealogy, then on Earliest Known Ancestors and complete the information in the red boxes.

  • Direct paternal line means your father’s father’s father’s line – as far up through all fathers as you can reach. This is your Y DNA lineage, but females should complete this information on general principles.
  • Direct maternal line means your mother’s mother’s mother’s line – as far up through all mothers that you can reach. This is your mitochondrial DNA lineage, so relevant for both males and females.

Completing all of the information, including the location, will help you and your matches as well when using the Matches Map.

Be sure to click Save when you’re finished.

Y DNA Filters

Y DNA has more filter options than autosomal.

The Y DNA filter, located to the right of the 12 Markers tab allows testers to filter by:

  • Genetic distance, meaning how many mutations difference between you and your matches
  • Groups meaning group projects that the tester has joined
  • Tree status
  • Match date
  • Level of test taken

If none of your matches have taken the 111 marker test or you don’t match anyone at that level, that test won’t show up on your list.

Y DNA Table View

As with Family Finder, the Table View is more condensed and additional features are available on the right side of each match. For details, please review the Family Finder section.

If you’re looking for the old Y DNA TiP report, it’s now at the far right of each match.

The actual calculator hasn’t changed yet. I know people were hoping for the new Y DNA aging in this release, but that’s yet to follow.

Other Pages

Other pages like the Big Y and Mitochondrial DNA did not receive new features or functionality in this release, but do sport new user-friendly tooltips.

I lost track, but I counted over 100 tooltips added across the platform, and this is just the beginning.

There are probably more new features and functionality that I haven’t stumbled across just yet.

And yes, we are going to find a few bugs. That’s inevitable with something this large. Please report anything you find to FamilyTreeDNA.

Oh wait – I almost forgot…

New Videos

I understand that there are in the ballpark of 50 new videos that are being added to the new Help Center, either today or very shortly.

When I find out more, I’ll write an article about what videos are available and where to find them. People learn in various ways. Videos are often requested and will be a popular addition. I considered making videos, but that’s almost impossible for anyone besides the vendor because the names on screens either need to be “fake” or the screen needs to be blurred.

So hurray – very glad to hear these are imminent!

Stay Tuned

Stay tuned for new developments. As Lior said, FamilyTreeDNA is investing heavily in genetic genealogy and there’s more to come.

My Mom used to say that the “proof is in the pudding.” I’d say the myDNA/FamilyTreeDNA leadership team has passed this initial test with flying colors.

Of course, there’s more to do, but I’m definitely grateful for this lovely pudding. Thank you – thank you!

I can’t wait to get started and see what new gems await.

Take a Look!

Sign in and take a look for yourself.

Do you have more matches?

Are your matches more accurate?

How about predicted relationships?

How has this new release affected you?

What do you like the best?

FREE LIVE Presentation: Turning AutoClusters into Solutions at MyHeritage

You’re invited to join me for a FREE Facebook LIVE presentation on May 24th, at 2 PM EST.

We’ll be talking about tips and tricks to turn “AutoClusters into Solutions at MyHeritage.”

AutoClusters are a great tool and few of us are using them to their fullest potential. I know I wasn’t.

MyHeritage will be hosting this seminar on their Facebook page, LIVE.

I’ve done a few of these LIVE sessions before and they are SO MUCH FUN for everyone!!! They’re super popular too. We’ve had between 14,000 and 20,000 people view each one.

Want to Hear a Secret?

I’ve made three discoveries while preparing for this presentation – in the first cluster alone. I can barely stop. Who needs sleep anyway?

No, I’m really not kidding. My great-grandmother had a missing brother. We all assumed he died because we, today, couldn’t find hide nor hair of him.

Well, guess what – he’s not missing anymore. His descendants didn’t know where he came from, and we didn’t know where he went. It’s almost impossible to connect someone backward in time if you don’t have any geographic link at all.

AutoClusters ARE genetic links, from either end.

No Registration Required

You don’t need to sign up in advance. Just set a reminder and show up at the proper date and time. There’s enough “seating” for everyone, and no wait either. Can’t join us on May 24th at 2 PM EST? Don’t worry. MyHeritage records the sessions and you can watch them later.

Upload DNA Files Now!

I’m giving you this early heads-up so that you have time to upload your DNA file to MyHeritage, and the DNA of your close relatives whose tests you manage (with permission of course), if you haven’t yet done so. If you upload now, you’ll have access to all of the tools before the session.

Here’s what you need to do.

  1. Download your DNA file from either Ancestry, 23andMe, or FamilyTreeDNA. Step-by-step instructions for downloading your DNA file from each vendor can be found here.
  2. Upload your DNA file to MyHeritage. Step-by-step instructions for uploading to MyHeritage are found here.
  3. Upload or create a tree at MyHeritage or connect your relative’s DNA to their profile card in your existing tree.
  4. If you already have a fully paid data and records subscription plan at MyHeritage, you will receive all of the advanced tools, for free – including AutoClusters. You can try a free subscription if you don’t already have one, here.
  5. If you don’t have a data and records subscription plan, you’ll need to pay the $29 unlock for the advanced DNA tools, including AutoClusters, which is less expensive and quicker than testing again.

If you have close relatives who have tested elsewhere, you might want to ask them to transfer to MyHeritage as well. If they aren’t personally interested but will download their file, you can upload it and manage their DNA from your MyHeritage account.

You’ll find tools and matches at MyHeritage not available in other databases. MyHeritage is very popular in Europe. I’ve found some of my closest Dutch and German matches at MyHeritage, including in clusters.

Which is, of course, another reason to watch “Turning AutoClusters into Solutions at MyHeritage!”

Hope to see you there!

A Triangulation Checklist Born From the Question; “Why NOT Use Close Relatives for Triangulation?”

One of my readers asked why we don’t use close relatives for triangulation.

This is a great question because not using close relatives for triangulation seems counter-intuitive.

I used to ask my kids and eventually my students and customers if they wanted the quick short answer or the longer educational answer.

The short answer is “because close relatives are too close to reliably form the third leg of the triangle.” Since you share so much DNA with close relatives, someone matching you who is identical by chance can also match them for exactly the same reason.

If you trust me and you’re good with that answer, wonderful. But I hope you’ll keep reading because there’s so much to consider, not to mention a few gotchas. I’ll share my methodology, techniques, and workarounds.

We’ll also discuss absolutely wonderful ways to utilize close relatives in the genetic genealogical process – just not for triangulation.

At the end of this article, I’ve provided a working triangulation checklist for you to use when evaluating your matches.

Let’s go!

The Step-by-Step Educational Answer😊

Some people see “evidence” they believe conflicts with the concept that you should not use close relatives for triangulation. I understand that, because I’ve gone down that rathole too, so I’m providing the “educational answer” that explains exactly WHY you should not use close relatives for triangulation – and what you should do.

Of course, we need to answer the question, “Who actually are close relatives?”

I’ll explain the best ways to best utilize close relatives in genetic genealogy, and why some matches are deceptive.

You’ll need to understand the underpinnings of DNA inheritance and also of how the different vendors handle DNA matching behind the scenes.

The purpose of autosomal DNA triangulation is to confirm that a segment is passed down from a particular ancestor to you and a specific set of your matches.

Triangulation, of course, implies 3, so at least three people must all match each other on a reasonably sized portion of the same DNA segment for triangulation to occur.

Matching just one person only provides you with one path to that common ancestor. It’s possible that you match that person due to a different ancestor that you aren’t aware of, or due to chance recombination of DNA.

It’s possible that your or your match inherited part of that DNA from your maternal side and part from your paternal side, meaning that you are matching that other person’s DNA by chance.

I wrote about identical by descent (IBD), which is an accurate genealogically meaningful match, and identical by chance (IBC) which is a false match, in the article Concepts – Identical by…Descent, State, Population and Chance.

I really want you to understand why close relatives really shouldn’t be used for triangulation, and HOW close relative matches should be used, so we’re going to discuss all of the factors that affect and influence this topic – both the obvious and little-understood.

  • Legitimate Matches
  • Inheritance and Triangulation
  • Parental Cross-Matching
  • Parental Phasing
  • Automatic Phasing at FamilyTreeDNA
  • Parental Phasing Caveats
  • Pedigree Collapse
  • Endogamy
  • How Many Identical-by-Chance Matches Will I Have?
  • DNA Doesn’t Skip Generations (Seriously, It Doesn’t)
  • Your Parents Have DNA That You Don’t (And How to Use It)
  • No DNA Match Doesn’t Mean You’re Not Related
  • Imputation

  • Testing Close Relatives is VERY Useful – Just Not for Triangulation
  • Triangulated Matches
  • Building Triangulation Evidence – Ingredients and a Recipe

  • Siblings
  • How False Positives Work and How to Avoid Them
  • Distant Cousins Are Best for Triangulation & Here’s Why
  • Where Are We? A Triangulation Checklist for You!
  • The Bottom Line

Don’t worry, these sections are logical and concise. I considered making this into multiple articles, but I really want it in one place for you. I’ve created lots of graphics with examples to help out.

Let’s start by dispelling a myth.

DNA Doesn’t Skip Generations!

Recently, someone emailed to let me know that they had “stopped listening to me” in a presentation when I said that if a match did not also match one of your parents, it was a false match. That person informed me that they had worked on their tree for three years at Ancestry and they have “proof” of DNA skipping generations.

Nope, sorry. That really doesn’t happen, but there are circumstances when a person who doesn’t understand either how DNA works, or how the vendor they are using presents DNA results could misunderstand or misinterpret the results.

You can watch my presentation, RootsTech session, DNA Triangulation: What, Why and How, for free here. I’m thrilled that this session is now being used in courses at two different universities.

DNA really doesn’t skip generations. You CANNOT inherit DNA that your parents didn’t have.

Full stop.

Your children cannot inherit DNA from you that you don’t carry. If you don’t have that DNA, your children and their descendants can’t have it either, at least not from you. They of course do inherit DNA from their other parent.

I think historically, the “skipping generations” commentary was connected to traits. For example, Susie has dimples (or whatever) and so did her maternal grandmother, but her mother did not, so Susie’s dimples were said to have “skipped a generation.” Of course, we don’t know anything about Susie’s other grandparents, if Susie’s parents share ancestors, recessive/dominant genes or even how many genetic locations are involved with the inheritance of “dimples,” but I digress.

DNA skipping generations is a fallacy.

You cannot legitimately match someone that your parent does not, at least not through that parent’s side of the tree.

But here’s the caveat. You can’t match someone one of your parents doesn’t with the rare exception of:

  • Relatively recent pedigree collapse that occurs when you have the same ancestors on both sides of your tree, meaning your parents are related, AND
  • The process of recombination just happened to split and recombine a segment of DNA in segments too small for your match to match your parents individually, but large enough when recombined to match you.

We’ll talk about that more in a minute.

However, the person working with Ancestry trees can’t make this determination because Ancestry doesn’t provide segment information. Ancestry also handles DNA differently than other vendors, which we’ll also discuss shortly.

We’ll review all of this, but let’s start at the beginning and explain how to determine if our matches are legitimate, or not.

Legitimate Matches

Legitimate matches occur when the DNA of your ancestor is passed from that ancestor to their descendants, and eventually to you and a match in an unbroken pathway.

Unbroken means that every ancestor between you and that ancestor carried and then passed on the segment of the ancestor’s DNA that you carry today. The same is true for your match who carries the same segment of DNA from your common ancestor.

False positive matches occur when the DNA of a male and female combine randomly to look like a legitimate match to someone else.

Thankfully, there are ways to tell the difference.

Inheritance and Triangulation

Remember, you inherit two copies of each of your chromosomes 1-22, one copy from your mother and one from your father. You inherit half of the DNA that each parent carries, but it’s mixed together in you so the labs can’t readily tell which nucleotide, A, C, T, or G you received from which parent. I’m showing your maternal and paternal DNA in the graphic below, stacked neatly together in a column – but in reality, it could be AC in one position and CA in the next.

For matching all that matters is the nucleotide that matches your match is present in one of those two locations. In this case, A for your mother’s side and C for your father’s side. If you’re interested, you can read more about that in the article, Hit a Genealogy Home Run Using Your Double-Sided Two-Faced Chromosomes While Avoiding Imposters.

You can see in this example that you inherited all As from your Mom and all Cs from your Dad.

  • A legitimate maternal match would match you on all As on this particular example segment.
  • A legitimate paternal match would match you on all Cs on this particular segment.
  • A false positive match will match you on some random combination of As and Cs that make it look like they match you legitimately, but they don’t.
  • A false positive match will NOT match either your mother or your father.

To be very clear, technically a false positive match DOES match your DNA – but they don’t match your DNA because you share a common ancestor with your match. They match you because random recombination on their side causes you to match each other by chance.

In other words, if part of your DNA came from your Mom’s side and part from your Dad’s but it randomly fell in the correct positional order, you’d still match someone whose DNA was from only their mother or father’s side. That’s exactly the situation shown above and below.

Looking at our example again, it’s evident that your identical by chance (IBC) match’s A locations (1, 3, 5, 7 & 9) will match your Mom. C locations (2, 4, 6 8, & 10) will match your Dad, but the nonmatching segments interleaved in-between that match alternating parents will prevent your match from matching either of your parents. In other words, out of 10 contiguous locations in our example, your IBC match has 5 As alternated with 5 Cs, so they won’t match either of your parents who have 10 As or 10 Cs in a row.

This recombination effect can work in either direction. Either or both matching people’s DNA could be randomly mixed causing them to match each other, but not their parents.

Regardless of whose DNA is zigzagging back and forth between maternal and paternal, the match is not genealogical and does not confirm a common ancestor.

This is exactly why triangulation works and is crucial.

If you legitimately match a third person, shown below, on your maternal side, they will match you, your first legitimate maternal match, and your Mom because they carry all As. But they WON’T match the person who is matching you because they are identical by chance, shown in grey below.

The only person your identical by chance match matches in this group is you because they match you because of the chance recombination of parental DNA.

That third person WILL also match all other legitimate maternal matches on this segment.

In the graphic above, we see that while the grey identical by chance person matches you because of the random combination of As from your mother and Cs from your father, your legitimate maternal matches won’t match your identical by chance match.

This is the first step in identifying false matches.

Parental Cross-Matching

Removing the identical by chance match, and adding in the parents of your legitimate maternal match, we see that your maternal match, above, matches you because you both have all As inherited from one parent, not from a combination of both parents.

We know that because we can see the DNA of both parents of both matches in this example.

The ideal situation occurs when two people match and they have both had their parents tested. We need to see if each person matches the other person’s parents.

We can see that you do NOT match your match’s father and your match does NOT match your father.

You do match your match’s mother and your match does match your mother. I refer to this as Parental Cross-matching.

Your legitimate maternal matches will also match each other and your mother if she is available for testing.

All the people in yellow match each other, while the two parents in gray do not match any of your matches. An entire group of legitimate maternal matches on this segment, no matter how many, will all match each other.

If another person matches you and the other yellow people, you’ll still need to see if you match their parents, because if not, that means they are matching you on all As because their two parents DNA combined just happened, by chance, to contribute an A in all of those positions.

In this last example, your new match, in green, matches you, your legitimate match and both of your mothers, BUT, none of the four yellow people match either of the new match’s parents. You can see that the new green match inherited their As from the DNA of their mother and father both, randomly zigzagging back and forth.

The four yellow matches phase parentally as we just proved with cross matching to parents. The new match at first glance appears to be a legitimate match because they match all of the yellow people – but they aren’t because the yellow people don’t match the green person’s parents.

To tell the difference between legitimate matches and identical by chance matches, you need two things, in order.

  • Parental matching known as parental phasing along with parental cross-matching, if possible, AND
  • Legitimate identical by descent (IBD) triangulated matches

If you have the ability to perform parental matching, called phasing, that’s the easiest first step in eliminating identical by chance matches. However, few match pairs will have parents for everyone. You can use triangulation without parental phasing if parents aren’t available.

Let’s talk about both, including when and how close relatives can and cannot be used.

Parental Phasing

The technique of confirming your match to be legitimate by your match also matching one of your parents is called parental phasing.

If we have the parents of both people in a match pair available for matching, we can easily tell if the match does NOT match either parent. That’s Parental Cross Matching. If either match does NOT match one of the other person’s parents, the match is identical by chance, also known as a false positive.

See how easy that was!

If you, for example, is the only person in your match pair to have parents available, then you can parentally phase the match on your side if your match matches your parents. However, because your match’s parents are unavailable, your match to them cannon tbe verified as legitimate on their side. So you are not phased to their parents.

If you only have one of your parents available for matching, and your match does not match that parent, you CANNOT presume that because your match does NOT match that parent, the match is a legitimate match for the other, missing, parent.

There are four possible match conditions:

  • Maternal match
  • Paternal match
  • Matches neither parent which means the match is identical by chance meaning a false positive
  • Matches both parents in the case of pedigree collapse or endogamy

If two matching people do match one parent of both matches (parental cross-matching), then the match is legitimate. In other words, if we match, I need to match one of your parents and you need to match one of mine.

It’s important to compare your matches’ DNA to generationally older direct family members such as parents or grandparents, if that’s possible. If your grandparents are available, it’s possible to phase your matches back another generation.

Automatic Phasing at FamilyTreeDNA

FamilyTreeDNA automatically phases your matches to your parents if you test that parent, create or upload a GEDCOM file, and link your test and theirs to your tree in the proper places.

FamilyTreeDNA‘s Family Matching assigns or “buckets” your matches maternally and paternally. Matches are assigned as maternal or paternal matches if one or both parents have tested.

Additionally, FamilyTreeDNA uses triangulated matches from other linked relatives within your tree even if your parents have not tested. If you don’t have your parents, the more people you identify and link to your tree in the proper place, the more people will be assigned to maternal and paternal buckets. FamilyTreeDNA is the only vendor that does this. I wrote about this process in the article, Triangulation in Action at Family Tree DNA.

Parental Phasing Caveats

There are very rare instances where parental phasing may be technically accurate, but not genealogically relevant. By this, I mean that a parent may actually match one of your matches due to endogamy or a population level match, even if it’s considered a false positive because it’s not relevant in a genealogical timeframe.

Conversely, a parent may not match when the segment is actually legitimate, but it’s quite rare and only when pedigree collapse has occurred in a very specific set of circumstances where both parents share a common ancestor.

Let’s take a look at that.

Pedigree Collapse

It’s not terribly uncommon in the not-too-distant past to find first cousins marrying each other, especially in rather closely-knit religious communities. I encounter this in Brethren, Mennonite and Amish families often where the community was small and out-marrying was frowned upon and highly discouraged. These families and sometimes entire church congregations migrated cross-country together for generations.

When pedigree collapse is present, meaning the mother and father share a common ancestor not far in the past, it is possible to inherit half of one segment from Mom and the other half from Dad where those halves originated with the same ancestral couple.

For example, let’s say the matching segment between you and your match is 12 cM in length, shown below. You inherited the blue segment from your Dad and the neighboring peach segment from Mom – shown just below the segment numbers. You received 6 cM from both parents.

Another person’s DNA does match you, shown in the bottom row, but they are not shown on the DNA match list of either of your parents. That’s because the DNA segments of the parents just happened to recombine in 6 cM pieces, respectively, which is below the 7 cM matching threshold of the vendor in this example.

If the person matched you at 12 cM where you inherited 8 cM from one parent and 4 from the other, that person would show on one parent’s match list, but not the other. They would not be on the parent’s match list who contributed only 4 cM simply because the DNA divided and recombined in that manner. They would match you on a longer segment than they match your parent at 8 cM which you might notice as “odd.”

Let’s look at another example.

If the matching segment is 20 cM, the person will match you and both of your parents on different pieces of the same segment, given that both segments are above 7 cM. In this case, your match who matches you at 20 cM will match each of your parents at 10 cM.

You would be able to tell that the end location of Dad’s segment is the same as the start location of Mom’s segment.

This is NOT common and is NOT the “go to” answer when you think someone “should” match your parent and does not. It may be worth considering in known pedigree collapse situations.

You can see why someone observing this phenomenon could “presume” that DNA skipped a generation because the person matches you on segments where they don’t match your parent. But DNA didn’t skip anything at all. This circumstance was caused by a combination of pedigree collapse, random division of DNA, then random recombination in the same location where that same DNA segment was divided earlier. Clearly, this sequence of events is not something that happens often.

If you’ve uploaded your DNA to GEDmatch, you can select the “Are your parents related?” function which scans your DNA file for runs of homozygosity (ROH) where your DNA is exactly the same in both parental locations for a significant distance. This suggests that because you inherited the exact same sequence from both parents, that your parents share an ancestor.

If your parents didn’t inherit the same segment of DNA from both parents, or the segment is too short, then they won’t show as “being related,” even if they do share a common ancestor.

Now, let’s look at the opposite situation. Parental phasing and ROH sometimes do occur when common ancestors are far back in time and the match is not genealogically relevant.

Endogamy

I often see non-genealogical matching occur when dealing with endogamy. Endogamy occurs when an entire population has been isolated genetically for a long time. In this circumstance, a substantial part of the population shares common DNA segments because there were few original population founders. Much of the present-day population carries that same DNA. Many people within that population would match on that segment. Think about the Jewish community and indigenous Americans.

Consider our original example, but this time where much of the endogamous population carries all As in these positions because one of the original founders carried that nucleotide sequence. Many people would match lots of other people regardless of whether they are a close relative or share a distant ancestor.

People with endogamous lines do share relatives, but that matching DNA segment originated in ancestors much further back in time. When dealing with endogamy, I use parental phasing as a first step, if possible, then focus on larger matches, generally 20 cM or greater. Smaller matches either aren’t relevant or you often can’t tell if/how they are.

At FamilyTreeDNA, people with endogamy will find many people bucketed on the “Both” tab meaning they triangulate with people linked on both sides of the tester’s tree.

An example of a Jewish person’s bucketed matches based on triangulation with relatives linked in their tree is shown above.

Your siblings, their children, and your children will be related on both your mother’s and father’s sides, but other people typically won’t be unless you have experienced either pedigree collapse where you are related both maternally and paternally through the same ancestors or you descend from an endogamous population.

How Many Identical-by-Chance Matches Will I Have?

If you have both parents available to test, and you’re not dealing with either pedigree collapse or endogamy, you’ll likely find that about 15-20% of your matches don’t match your parents on the same segment and are identical by chance.

With endogamy, you’ll have MANY more matches on your endogamous lines and you’ll have some irrelevant matches, often referred to as “false positive” matches even though they technically aren’t, even using parental phasing.

Your Parents Have DNA That You Don’t

Sometimes people are confused when reviewing their matches and their parent’s match to the same person, especially when they match someone and their parent matches them on a different or an additional segment.

If you match someone on a specific segment and your parents do not, that’s a false positive FOR THAT SEGMENT. Every segment has its own individual history and should be evaluated individually. You can match someone on two segments, one from each parent. Or three segments, one from each parent and one that’s identical by chance. Don’t assume.

Often, your match will match both you and your parent on the same segment – which is a legitimate parentally phased match.

But what if your match matches your parent on a different segment where they don’t match you? That’s a false positive match for you.

Keep in mind that it is possible for one of your matches to match your parent on a separate or an additional segment that IS legitimate. You simply didn’t inherit that particular segment from your parent.

That’s NOT the same situation as someone matching you that does NOT match one of your parents on the same segment – which is an identical by chance or false match.

Your parent having a match that does not match you is the reverse situation.

I have several situations where I match someone on one segment, and they match my parent on the same segment. Additionally, that person matches my parent on another segment that I did NOT inherit from that parent. That’s perfectly normal.

Remember, you only inherit half of your parent’s DNA, so you literally did NOT inherit the other half of their DNA. Your mother, for example, should have twice as many matches as you on her side because roughly half of her matches won’t match you.

That’s exactly why testing your parents and close family members is so critical. Their matches are as valid and relevant to your genealogy as your own. The same is true for other relatives, such as aunts and uncles with whom you share ALL of the same ancestors.

You need to work with your family member’s matches that you don’t share.

No DNA Match Doesn’t Mean You’re Not Related

Some people think that not matching someone on a DNA test is equivalent to saying they aren’t related. Not sharing DNA doesn’t mean you’re not related.

People are often disappointed when they don’t match someone they think they should and interpret that to mean that the testing company is telling them they “aren’t related.” They are upset and take issue with this characterization. But that’s not what it means.

Let’s analyze this a bit further.

First, not sharing DNA with a second cousin once removed (2C1R) or more distant does NOT mean you’re NOT related to that person. It simply means you don’t share any measurable DNA ABOVE THE VENDOR THRESHOLD.

All known second cousins match, but about 10% of third cousins don’t match, and so forth on up the line with each generation further back in time having fewer cousins that match each other.

If you have tested close relatives, check to see if that cousin matches your relatives.

Second, it’s possible to match through the “other” or unexpected parent. I certainly didn’t think this would be the case in my family, because my father is from Appalachia and my mother’s family is primarily from the Netherlands, Germany, Canada, and New England. But I was wrong.

All it took was one German son that settled in Appalachia, and voila, a match through my mother that I surely thought should have been through my father’s side. I have my mother’s DNA and sure enough, my match that I thought should be on my father’s side matches Mom on the same segment where they match me, along with several triangulated matches. Further research confirmed why.

I’ve also encountered situations where I legitimately match someone on both my mother’s and father’s side, on different segments.

Third, imputation can be important for people who don’t match and think they should. Imputation can also cause matching segment length to be overreported.

Ok, so what’s imputation and why do I care?

Imputation

Every DNA vendor today has to use some type of imputation.

Let me explain, in general, what imputation is and why vendors use it.

Over the years, DNA processing vendors who sell DNA chips to testing companies have changed their DNA chips pretty substantially. While genealogical autosomal tests test about 700,000 DNA locations, plus or minus, those locations have changed over time. Today, some of these chips only have 100,000 or so chip locations in common with chips either currently or previously utilized by other vendors.

The vendors who do NOT accept uploads, such as 23andMe or Ancestry, have to develop methods to make their newest customers on their DNA processing vendor’s latest chip compatible with their first customer who was tested on their oldest chip – and all iterations in-between.

Vendors who do accept transfers/uploads from other vendors have to equalize any number of vendors’ chips when their customers upload those files.

Imputation is the scientific way to achieve this cross-platform functionality and has been widely used in the industry since 2017.

Imputation, in essence, fills in the blanks between tested locations with the “most likely” DNA found in the human population based on what’s surrounding the blank location.

Think of the word C_T. There are a limited number of letters and words that are candidates for C_T. If you use the word in a sentence, your odds of accuracy increase dramatically. Think of a genetic string of nucleotides as a sentence.

Imputation can be incorrect and can cause both false positive and false negative matches.

For the most part, imputation does not affect close family matches as much as more distant matches. In other words, imputation is NOT going to cause close family members not to match.

Imputation may cause more distant family members not to match, or to have a false positive match when imputation is incorrect.

Imputation is actually MUCH less problematic than I initially expected.

The most likely effect of imputation is to cause a match to be just above or below the vendor threshold.

How can we minimize the effects of imputation?

  • Generally, the best result will be achieved if both people test at the same vendor where their DNA is processed on the same chip and less imputation is required.
  • Upload the results of both people to both MyHeritage and FamilyTreeDNA. If your match results are generally consistent at those vendors, imputation is not a factor.
  • GEDmatch does not use imputation but attempts to overcome files with low overlapping regions by allowing larger mismatch areas. I find their matches to be less accurate than at the various vendors.

Additionally, Ancestry has a few complicating factors.

Ancestry Issues

AncestryDNA is different in three ways.

  • Ancestry doesn’t provide segment information so it’s impossible to triangulate or identify the segment or chromosome where people match. There is no chromosome browser or triangulation tool.
  • Ancestry down-weights and removes some segments in areas where they feel that people are “too matchy.” You can read Ancestry’s white papers here and here.

These “personal pileup regions,” as they are known, can be important genealogically. In my case, these are my mother’s Acadian ancestors. Yes, this is an endogamous population and also suffers from pedigree collapse, but since this is only one of my mother’s great-grandparents, this match information is useful and should not be removed.

  • Ancestry doesn’t show matches in common if the shared segments are less than 20cM. Therefore, you may not see someone on a shared match list with a relative when they actually are a shared match.

If two people both match a third person on less than a 20 cM segment at Ancestry, the third person won’t appear on the other person’s shared match list. So, if I match John Doe on 19 cM of DNA, and I looked at the shared matches with my Dad, John Doe does NOT appear on the shared match list of me and my Dad – even though he is a match to both of us at 19 cM.

The only way to determine if John Doe is a shared match is to check my Dad’s and my match list individually, which means Dad and I will need to individually search for John Doe.

Caveat here – Ancestry’s search sometimes does not work correctly.

Might someone who doesn’t understand that the shared match list doesn’t show everyone who shares DNA with both people presume that the ancestral DNA of that ancestor “skipped a generation” because John Doe matches me with a known ancestor, and not Dad on our shared match list? I mean, wouldn’t you think that a shared match would be shown on a tab labeled “Shared Matches,” especially since there is no disclaimer?

Yes, people can be forgiven for believing that somehow DNA “skipped” a generation in this circumstance, especially if they are relatively inexperienced and they don’t understand Ancestry’s anomalies or know that they need to or how to search for matches individually.

Even if John Doe does match me and Dad both, we still need to confirm that it’s on the same segment AND it’s a legitimate match, not IBC. You can’t perform either of these functions at Ancestry, but you can elsewhere.

Ancestry WorkArounds

To obtain this functionality, people can upload their DNA files for free to both FamilyTreeDNA and MyHeritage, companies that do provide full shared DNA reporting (in common with) lists of ALL matches and do provide segment information with chromosome browsers. Furthermore, both provide triangulation in different ways.

Matching is free, but an inexpensive unlock is required at both vendors to access advanced tools such as Family Matching (bucketing) and triangulation at Family Tree DNA and phasing/triangulation at MyHeritage.

I wrote about Triangulation in Action at FamilyTreeDNA, here.

MyHeritage actually brackets triangulated segments for customers on their chromosome browser, including parents, so you get triangulation and parental phasing at the same time if you and your parent have both tested or uploaded your DNA file to MyHeritage. You can upload, for free, here.

In this example, my mother is matching to me in red on the entire length of chromosome 18, of course, and three other maternal cousins triangulate with me and mother inside the bracketed portion of chromosome 18. Please note that if any one of the people included in the chromosome browser comparison do not triangulate, no bracket is drawn around any others who do triangulate. It’s all or nothing. I remove people one by one to see if people triangulate – or build one by one with my mother included.

I wrote about Triangulation in Action at MyHeritage, here.

People can also upload to GEDmatch, a third-party site. While GEDmatch is less reliable for matching, you can adjust your search thresholds which you cannot do at other vendors. I don’t recommend routinely working below 7 cM. I occasionally use GEDmatch to see if a pedigree collapse segment has recombined below another vendor’s segment matching threshold.

Do NOT check the box to prevent hard breaks when selecting the One-to-One comparison. Checking that box allows GEDmatch to combine smaller matching segments into mega-segments for matching.

I wrote about Triangulation in Action at GEDmatch, here.

Transferring/Uploading Your DNA 

If you want to transfer your DNA to one of these vendors, you must download the DNA file from one vendor and upload it to another. That process does NOT remove your DNA file from the vendor where you tested, unless you select that option entirely separately.

I wrote full step-by-step transfer/upload instructions for each vendor, here.

Testing Close Relatives Is VERY Useful – Just Not for Triangulation

Of course, your best bet if you don’t have your parents available to test is to test as many of your grandparents, great-aunts/uncles, aunts, and uncles as possible. Test your siblings as well, because they will have inherited some of the same and some different segments of DNA from your parents – which means they carry different pieces of your ancestors’ DNA.

Just because close relatives don’t make good triangulation candidates doesn’t mean they aren’t valuable. Close relatives are golden because when they DO share a match with you, you know where to start looking for a common ancestor, even if your relative matches that person on a different segment than you do.

Close relatives are also important because they will share pieces of your common ancestor’s DNA that you don’t. Their matches can unlock the answers to your genealogy questions.

Ok, back to triangulation.

Triangulated Matches

A triangulated match is, of course, when three people all descended from a common ancestor and match each other on the same segment of DNA.

That means all three people’s DNA matches each other on that same segment, confirming that the match is not by chance, and that segment did descend from a common ancestor or ancestral couple.

But, is this always true? You’re going to hate this answer…

“It depends.”

You knew that was coming, didn’t you! 😊

It depends on the circumstances and relationships of the three people involved.

  • One of those three people can match the other two by chance, not by descent, especially if two of those people are close relatives to each other.
  • Identical by chance means that one of you didn’t inherit that DNA from one single parent. That zigzag phenomenon.
  • Furthermore, triangulated DNA is only valid as far back as the closest common ancestor of any two of the three people.

Let’s explore some examples.

Building Triangulation Evidence – Ingredients and a Recipe

The strongest case of triangulation is when:

  • You and at least two additional cousins match on the same segment AND
  • Descend through different children of the common ancestral couple

Let’s look at a valid triangulated match.

In this first example, the magenta segment of DNA is at least partially shared by four of the six cousins and triangulates to their common great-grandfather. Let’s say that these cousins then match with two other people descended from different children of their great-great-great-grandparents on this same segment. Then the entire triangulation group will have confirmed that segment’s origin and push the descent of that segment back another two generations.

These people all coalesce into one line with their common great-grandparents.

I’m only showing 3 generations in this triangulated match, but the concept is the same no matter how many generations you reach back in time. Although, over time, segments inherited from any specific ancestor become smaller and smaller until they are no longer passed to the next generation.

In this pedigree chart, we’re only tracking the magenta DNA which is passed generation to generation in descendants.

Eventually, of course, those segments become smaller and indistinguishable as they either aren’t passed on at all or drop below vendor matching thresholds.

This chart shows the average amount of DNA you would carry from each generational ancestor. You inherit half of each parent’s DNA, but back further than that, you don’t receive exactly half of any ancestor’s DNA in any generation. Larger segments are generally cut in two and passed on partially, but smaller segments are often either passed on whole or not at all.

On average, you’ll carry 7 cM of your eight-times-great-grandparents. In reality, you may carry more or you may not carry any – and you are unlikely to carry the same segment as any random other descendants but we know it happens and you’ll find them if enough (or the right) descendants test.

Putting this another way, if you divide all of your approximate 7000 cM of DNA into 7 cM segments of equal length – you’ll have 1000 7 cM segments. So will every other descendant of your eight-times-great-grandparent. You can see how small the chances are of you both inheriting that same exact 7 cM segment through ten inheritance/transmission events, each. Yet it does happen.

I have several triangulated matches with descendants of Charles Dodson and his wife, Anne through multiple of their 9 (or so) children, ten generations back in my tree. Those triangulated matches range from 7-38 cM. It’s possible that those three largest matches at 38 cM could be related through multiple ancestors because we all have holes in our trees – including Anne’s surname.

Click to enlarge image

It helps immensely that Charles Dodson had several children who were quite prolific as well.

Of course, the further back in time, the more “proof” is necessary to eliminate other unknown common ancestors. This is exactly why matching through different children is important for triangulation and ancestor confirmation.

The method we use to confirm the common ancestor is that all of the descendants who match the tester on the same segment all also match each other. This greatly reduces the chances that these people are matching by chance. The more people in the triangulation group, the stronger the evidence. Of course, parental phasing or cross-matching, where available is an added confirmation bonus.

In our magenta inheritance example, we saw that three of the males and one of the females from three different descendants of the great-grandparents all carry at least a portion of that magenta segment of great-grandpa’s DNA.

Now, let’s take a look at a different scenario.

Why can’t siblings or close relatives be used as two of the three people needed for triangulation?

Aunts and Uncles

We know that the best way to determine if a match is valid is by parental phasing – your match also matching to one of your parents.

If both parents aren’t available, looking for close family matches in common with your match is the next hint that genealogists seek.

Let’s say that you and your match both match your aunt or uncle in common or their children.

You and your aunts or uncles matching DNA only pushes your common ancestor back to your grandparents.

At that point, your match is in essence matching to a segment that belongs to your grandparents. Your matches’ DNA, or your grandparents’ DNA could have randomly recombined and you and your aunt/cousins could be matching that third person by chance.

Ok, then, what about siblings?

Siblings

The most recent common ancestor (MRCA) of you and someone who also matches your sibling is your parents. Therefore, you and your sibling actually only count as one “person” in this scenario. In essence, it’s the DNA of your parent(s) that is matching that third person, so it’s not true triangulation. It’s the same situation as above with aunts/uncles, except the common ancestor is closer than your grandparents.

The DNA of your parents could have recombined in both siblings to look like a match to your match’s family. Or vice versa. Remember Parental Cross-Matching.

If you and a sibling inherited EXACTLY the same segment of your Mom’s and Dad’s DNA, and you match someone by chance – that person will match your sibling by chance as well.

In this example, you can see that both siblings 1 and 2 inherited the exact same segments of DNA at the same locations from both of their parents.

Of course, they also inherited segments at different locations that we’re not looking at that won’t match exactly between siblings, unless they are identical twins. But in this case, the inherited segments of both siblings will match someone whose DNA randomly combined with green or magenta dots in these positions to match a cross-section of both parents.

How False Positives Work and How to Avoid Them

We saw in our first example, displayed again above, what a valid triangulated match looks like. Now let’s expand this view and take a look more specifically at how false positive matches occur.

On the left-hand (blue) side of this graphic, we see four siblings that descend through their father from Great-grandpa who contributed that large magenta segment of DNA. That segment becomes reduced in descendants in subsequent generations.

In downstream generations, we can see gold, white and green segments being added to the DNA inherited by the four children from their ancestor’s spouses. Dad’s DNA is shown on the left side of each child, and Mom’s on the right.

  • Blue Children 1 and 2 inherited the same segments of DNA from Mom and Dad. Magenta from Dad and green from Mom.
  • Blue Child 3 inherited two magenta segments from Dad in positions 1 and 2 and one gold segment from Dad in position 3. They inherited all white segments from Mom.
  • Blue Child 4 inherited all gold segments from Dad and all white segments from Mom.

The family on the blue left-hand side is NOT related to the pink family shown at right. That’s important to remember.

I’ve intentionally constructed this graphic so that you can see several identical by chance (IBC) matches.

Child 5, the first pink sibling carries a white segment in position 1 from Dad and gold segments in positions 2 and 3 from Dad. From Mom, they inherited a green segment in position 1, magenta in position 2 and green in position 3.

IBC Match 1 – Looking at the blue siblings, we see that based on the DNA inherited from Pink Child 5’s parents, Pink Child 5 matches Blue Child 4 with white, gold and gold in positions 1-3, even though they weren’t inherited from the same parent in Blue Child 4. I circled this match in blue.

IBC Match 2 – Pink Child 5 also matches Blue Children 1 and 2 (red circles) because Pink Child 5 has green, magenta, and green in positions 1-3 and so do Blue Children 1 and 2. However, Blue Children 1 and 2 inherited the green and magenta segments from Mom and Dad respectively, not just from one parent.

Pink Child 5 matches Blue Children 1, 2 and 4, but not because they match by descent, but because their DNA zigzags back and forth between the blue children’s DNA contributed by both parents.

Therefore, while Pink Child 5 matches three of the Blue Children, they do not match either parent of the Blue Children.

IBC Match 3 – Pink Child 6 matches Blue Child 3 with white, magenta and gold in positions 1-3 based on the same colors of dots in those same positions found in Blue Child 3 – but inherited both paternally and maternally.

You can see that if we had the four parents available to test, that none of the Pink Children would match either the Blue Children’s mother or father and none of the Blue Children would match either of the Pink Children’s mother or father.

This is why we can’t use either siblings or close family relatives for triangulation.

Distant Cousins Are Best for Triangulation & Here’s Why

When triangulating with 3 people, the most recent common ancestor (MRCA) intersection of the closest two people is the place at which triangulation turns into only two lines being compared and ceases being triangulation. Triangle means 3.

If siblings are 2 of the 3 matching people, then their parents are essentially being compared to the third person.

If you, your aunt/uncle, and a third person match, your grandparents are the place in your tree where three lines converge into two.

The same holds true if you’re matching against a sibling pair on your match’s side, or a match and their aunt/uncle, etc.

The further back in your tree you can push that MRCA intersection, the more your triangulated match provides confirming evidence of a common ancestor and that the match is valid and not caused by random recombination.

That’s exactly what the descendants of Charles Dodson have been able to do through triangulation with multiple descendants from several of his children.

It’s also worth mentioning at this point that the reason autosomal DNA testing uses hundreds/thousands of base pairs in a comparison window and not 3 or 6 dots like in my example is that the probability of longer segments of DNA simply randomly matching by chance is reduced with length and SNP density which is the number of SNP locations tested within that cM range.

Hence a 7 cM/500 SNP minimum is the combined rule of thumb. At that level, roughly half of your matches will be valid and half will be identical by chance unless you’re dealing with endogamy. Then, raise your threshold accordingly.

Ok, So Where are We? A Triangulation Checklist for You!

I know this has been a relatively long educational article, but it’s important to really understand that testing close relatives is VERY important, but also why we can’t effectively use them for triangulation.

Here’s a handy-dandy summary matching/triangulation checklist for you to use as you work through your matches.

  • You inherit half of each of your parents’ DNA. There is no other place for you to obtain or inherit your DNA. There is no DNA fairy sprinkling you with DNA from another source:)
  • DNA does NOT skip generations, although in occasional rare circumstances, it may appear that this happened. In this situation, it’s incumbent upon you, the genealogist, to PROVE that an exception has occurred if you really believe it has. Those circumstances might be pedigree collapse or perhaps imputation. You’ll need to compare matches at vendors who provide a chromosome browser, triangulation, and full shared match list information. Never assume that you are the exception without hard and fast proof. We all know about assume, right?
  • Your siblings inherit half of your parents’ DNA too, but not the same exact half of your parent’s DNA that you other siblings did (unless they are identical twins.) You may inherit the exact same DNA from either or both of your parents on certain segments.
  • Your matches may match your parents on different or an additional segment that you did not inherit.
  • Every segment has an individual history. Evaluate every matching segment separately. One matching segment with someone could be maternal, one paternal, and one identical by chance.
  • You can confirm matches as valid if your match matches one of your parents, and you match one of your match’s parents. Parental Phasing is when your match matches your parent. Parental Cross-Matching is when you both match one of each other’s parents. To be complete, both people who match each other need to match one of the parents of the other person. This rule still holds even if you have a known common ancestor. I can’t even begin to tell you how many times I’ve been fooled.
  • 15-20% (or more with endogamy) of your matches will be identical by chance because either your DNA or your match’s DNA aligns in such a way that while they match you, they don’t match either of your parents.
  • Your siblings, aunts, and uncles will often inherit the same DNA as you – which means that identical by chance matches will also match them. That’s why we don’t use close family members for triangulation. We do utilize close family members to generate common match hints. (Remember the 20 cM shared match caveat at Ancestry)
  • While your siblings, aunts, and uncles are too close to use for triangulation, they are wonderful to identify ancestral matches. Some of their matches will match you as well, and some will not because your close family members inherited segments of your ancestor’s DNA that you did not. Everyone should test their oldest family members.
  • Triangulate your close family member’s matches separately from your own to shed more light on your ancestors.
  • Endogamy may interfere with parental phasing, meaning you may match because you and/or your match may have inherited some of the same DNA segment(s) from both sides of your tree and/or more DNA than might otherwise be expected.
  • Pedigree collapse needs to be considered when using parental phasing, especially when the same ancestor appears on both sides of your family tree. You may share more DNA with a match than expected.
  • Conversely, with pedigree collapse, your match may not match your parents, or vice versa, if a segment happens to have recombined in you in a way that drops the matching segments of your parents beneath the vendor’s match threshold.
  • While you will match all of your second cousins, you will only match approximately 90% of your third cousins and proportionally fewer as your relationship reaches further back in time.
  • Not being a DNA match with someone does NOT mean you’re NOT related to them, unless of course, you’re a second cousin (2C) or closer. It simply means you don’t carry any common ancestral segments above vendor thresholds.
  • At 2C or closer, if you’re not a DNA match, other alternative situations need to be considered – including the transfer/upload of the wrong person’s DNA file.
  • Imputation, a scientific process required of vendors may interfere with matching, especially in more distant relatives who have tested on different platforms.
  • Imputation artifacts will be less obvious when people are more closely related, meaning closer relatives can be expected to match on more and larger segments and imputation errors make less difference.
  • Imputation will not cause close relatives, meaning 2C or closer, to not match each other.
  • In addition to not supporting segment matching information, Ancestry down-weights some segments, removes some matching DNA, and does not show shared matches below 20cM, causing some people to misinterpret their lack of common matches in various ways.
  • To resolve questions about matching issues at Ancestry, testers can transfer/upload their DNA files to MyHeritage, FamilyTreeDNA, and GEDmatch and look for consistent matches on the same segment. Start and end locations may vary to some extent between vendors, but the segment size should be basically in the same location and roughly the same size.
  • GEDmatch does not use imputation but allows larger non-matching segments to combine as a single segment which sometimes causes extremely “generous” matches. GEDmatch matching is less reliable than FamilyTreeDNA or MyHeritage, but you can adjust the matching thresholds.
  • The best situation for matching is for both people to test at the same vendor who supports and provides segment data and a chromosome browser such as 23andMe, FamilyTreeDNA, or MyHeritage.
  • Siblings cannot be used for triangulation because the most recent common ancestor (MRCA) between you and your siblings is your parents. Therefore, the “three” people in the triangulation group is reduced to two lines immediately.
  • Uncles and aunts should not be used for triangulation because the most recent common ancestors between you and your aunts and uncles are your grandparents.
  • Conversely, you should not consider triangulating with siblings and close family members of your matches as proof of an ancestral relationship.
  • A triangulation group of 3 people is only confirmation as far back as when two of those people’s lines converge and reach a common ancestor.
  • Identical by chance (IBC) matching occurs when DNA from the maternal and paternal sides are mixed positionally in the child to resemble a maternal/paternal side match with someone else.
  • Identical by chance DNA admixture (when compared to a match) could have occurred in your parents or grandparent’s generation, or earlier, so the further back in time that people in a triangulation group reach, the more reliable the triangulation group is likely to be.
  • The larger the segments and/or the triangulation group, the stronger the evidence for a specific confirmed common ancestor.
  • Early families with a very large number of descendants may have many matching and triangulated members, even 9 or 10 generations later.
  • While exactly 50% of each ancestor’s DNA is not passed in each generation, on average, you will carry 7 cM of your ancestors 10 generations back in your tree. However, you may carry more, or none.
  • The percentage of matching descendants decreases with each generation beyond great-grandparents.
  • The ideal situation for triangulation is a significant number of people, greater than three, who match on the same reasonably sized segment (7 cM/500 SNP or larger) and descend from the same ancestor (or ancestral couple) through different children whose spouses in descendant generations are not also related.
  • This means that tree completion is an important factor in match/triangulation reliability.
  • Triangulating through different children of the ancestral couple makes it significantly less likely that a different unknown common ancestor is contributing that segment of DNA – like an unknown wife in a descendant generation.

Whew!!!

The Bottom Line

Here’s the bottom line.

  1. Don’t use close relatives to triangulate.
  2. Use parents for Parental Phasing.
  3. Use Parental Cross-Matching when possible.
  4. Use close relatives to look for shared common matches that may lead to triangulation possibilities.
  5. Triangulate your close relatives’ DNA in addition to your own for bonus genealogical information. They will match people that you don’t.
  6. For the most reliable triangulation results, use the most distant relatives possible, descended through different children of the common ancestral couple.
  7. Keep this checklist of best practices, cautions, and caveats handy and check the list as necessary when evaluating the strength of any match or triangulation group. It serves as a good reminder for what to check if something seems “off” or unusual.

Feel free to share and pass this article (and checklist) on to your genealogy buddies and matches as you explain triangulation and collaborate on your genealogy.

Have fun!!!
