FOCUS Step 2: Finding the Y-DNA and Mitochondrial DNA of Your Ancestors

Posted on by

This is the third article in our FOCUS series, providing step-by-step instructions for identifying brick-walled ancestors.

These two articles detail the initial steps:

By now, you will have selected the ancestor you want to focus on identifying, and you have tools in your toolkit for working with DNA matches who have no trees.

You may have ordered DNA tests from multiple vendors and are waiting on results, so while you wait, we’ll start with finding the Y-DNA and mitochondrial DNA of your ancestors and identifying DNA testing candidates.

While it may sound counterintuitive, we’re going to be working with all of the major vendors, including FamilyTreeDNA, who actually tests for Y-DNA and mitochondrial DNA, plus WikiTree, 23andMe, MyHeritage, Ancestry, GEDmatch and FamilySearch. They are all quite useful in different ways.

This Type of Searching Is Different

Normally, when we search for brick-walled ancestors, we are searching backward in time. In other words, we begin with the last person we know and work back from there, hoping to identify the previous generation.

If we don’t know Lucy’s birth surname and she was born about 1750, and married William Moore in the late 1770s, we begin with what we do know in that timeframe.

Searching for our ancestor’s Y-DNA or mitochondrial DNA, and testers who carry that DNA, is fundamentally different because we begin with that ancestor and work forward in time.

In other words, if we want to find Lucy’s mitochondrial DNA, we begin with her daughters and track forward in time to the present. Hopefully, someone has already tested, and we can locate that result, but if not, we need to find people who descend through a specific path that carry Lucy’s mitochondrial DNA.

If we were searching for the Y-DNA of William Moore, we would look for his direct paternal descendant males who would carry the Moore surname.

Chicken or Egg?

I’ve been debating whether I should show you:

  1. How to locate and identify the Y-DNA and mitochondrial DNA of your ancestors first, or
  2. How to use Y-DNA and mitochondrial DNA (mtDNA) to help break through your brick wall first

I decided to write the “how to locate” article first because I don’t want you to skim over and ignore the ‘how to use’ article, thinking it’s irrelevant to your research because you don’t carry the Y-DNA and/or mtDNA of your brick-walled ancestor.

There are lots of avenues to locate the Y-DNA or mitochondrial DNA of your ancestors, something you definitely want to do. You’ll soon see that Y-DNA and mtDNA information can also assist with autosomal DNA results.

These are all pieces of your ancestor’s puzzle, and you never know which one will be the one to topple that wall.

Plus, you don’t know what you don’t know about that ancestor.

Let’s jump right in!

Who Carries the Y-DNA and Mitochondrial DNA of Your Ancestor?

As a quick refresher, only men can test for Y-DNA because only men have a Y chromosome which is inherited from their father. It’s passed in a direct paternal line from father to son, never mixed with DNA from the mother. Because it’s never divided during recombination like autosomal DNA, it’s uniquely useful for connecting lineages both recently and back in time hundreds and thousands of years.

Both Y-DNA and mitochondrial DNA incur occasional mutations that function as genetic breadcrumbs, making them incredibly useful for reassembling those specific family lines where genealogy paper trails have broken or been interrupted.

Mitochondrial DNA is passed from mothers to their children of both sexes, but only daughters pass it on. This means that in the current generation, males and females can both test for the mtDNA of their direct, mother-to-mother, matrilineal line.

Anyone, including males, who descends from an ancestor through all females can test for that ancestor’s mitochondrial DNA.

If you’re lucky, you’ll carry the Y-DNA or mitochondrial DNA of the ancestor you are seeking. If not, you’ll need to do one of two things:

  1. Determine if someone has already tested for that ancestor
  2. If not, find candidates to test

Y-DNA is generally easier because you at least (hopefully) have a surname to work with that has been passed from father to son, along with their Y chromosome.

Mitochondrial DNA is more challenging since surnames change each generation, so I’ve included several mitochondrial examples. Don’t skip over them, because the same research techniques apply to Y-DNA too, especially difficult cases.

If you’re a male, I strongly recommend that you order:

If you’re a female, you can only order the mtFull test, but you may be able to ask your father or brother or a male relative (with the surname in the lineage you seek) to take the Big Y-700 to represent your father’s family line. In other words, if you’re looking for a male Estes, you can ask your 2C Estes male who descends in a direct paternal line of all Estes men from your common ancestor.

Complete Versus Partial Tests

Haplogroup-only results derived from autosomal tests are fine as far as they go – but they don’t go very far. Most are what I would call midrange, providing testers with a haplogroup from maybe 2000 years ago, and some are much more distant than that. That isn’t to say they can’t be useful in a limited capacity, but Y-DNA and mtDNA have so much more potential.

You need comprehensive Y-DNA and mtDNA test results that identify all your haplogroup-defining mutations and can be refined as more people test and match family-level mutations.

Haplogroups are important, but you also need to match with other testers. Additionally, you’ll want the most complete haplogroup possible, because it will help you genealogically by providing a complete breadcrumb trail with the ability to identify your most recent common ancestor (MRCA).

FamilyTreeDNA is the only vendor that offers these complete tests that include matching with other testers, plus additional genealogy tools.

The Big Y-700 test scans for mutations in the stable portion of the Y chromosome and is the only way to obtain that personal-level information. It’s those recent mutations that will help place you within a biological family – or eliminate you from other lines, which prevents barking up the wrong tree.

The benefit of taking the test yourself, or sponsoring a test for someone willing to share their results with you, is that you have ready access to information through FamilyTreeDNA’s tools such as:

  • Matches with other Y-DNA and mtDNA testers
  • Matches Map (ancestor locations)
  • Advanced Matching, which provides a filtered list of people who match you on BOTH your Y-DNA or mitochondrial DNA AND your Family Finder autosomal test
  • Haplotype clusters (for mtDNA)
  • Your mutations
  • Block Tree (for Y-DNA)
  • Customized Discover tools

Click any image to enlarge

  • Discover’s Advanced Tools like the Match Time Tree, shown above, which displays your matches with their earliest known ancestors (EKA) together on the Time Tree
  • Globetrekker™ (for Y-DNA with mtDNA coming soon)
  • Up to 30 Ancient Connections
  • Up to 20 Notable Connections

FamilyTreeDNA’s free Discover tool, here, provides public information for everyone about haplogroups, but if you haven’t taken the test, you won’t receive matching and customized information described above, which is essential to genealogy.

Upgrades for Partial Tests

You may have previously tested at a lower level at FamilyTreeDNA.

For mtDNA, the early mtPlus test examined a portion of the mitochondria and provided matching at lower levels, as do the 12-111 marker Y-DNA tests. Both provide a predicted high-level basic or midrange haplogroup based on the mutation information available in those limited tests.

If you took an earlier, partial test, you can sign on to your account to upgrade by clicking on the “Big Y,” even though it’s greyed out. Grey simply indicates that you don’t currently have that level of test.

Click on “Full” to upgrade to the mtFull test.

Test Features at Various Levels

Depending on the type of test you take, and at which vendor, you may have a fully refined or partial haplogroup.

Discover provides a substantial amount of information if you receive a partial haplogroup:

A partial haplogroup is better than no haplogroup, but it’s also like working with one hand tied behind your back. If at all possible, you need to work with a full haplogroup and matches.

Testers who click through to Discover from their own test, or a test they manage, can view additional features not available in the free version.

The table below shows the four different ways you can access and view your ancestor’s haplogroup. Based on the testing level and/or how they tested, the haplogroup level will vary.

Clearly, the best scenario is when you either take the Big Y-700 or mtFull test yourself, or you have access to the test results of someone who takes that test to represent your ancestor’s DNA. Primary access confers the greatest amount of information, but you can still glean information in other ways.

*Note that often your ancestor’s haplogroup as reported by the Family Finder (autosomal) test is more refined, meaning closer in time, than the Y-DNA haplogroups predicted by STR tests, but both are always substantially less specific than the Big Y-700 test. As of the publication date of this article, Family Finder does not yet report a mitochondrial DNA haplogroup, but that is planned for the future.

This chart only includes features you would specifically use to identify an ancestor or ancestral lineage. There are other reports provided with your test that will be of interest. Discover provides about 14 reports that include various options.

Now we can envision:

  • The benefits of finding our ancestors’ Y-DNA and mtDNA
  • The benefits of obtaining the most refined haplogroup possible
  • The benefits of being able to view the results directly

You may not be able to achieve all of these, but even a partial haplogroup is better than no haplogroup at all, and a fully refined haplogroup, even if you can’t see everything in another tester’s account, is better than a partial haplogroup.

So, let’s see how to find your ancestors’ haplogroups. I collect them all, not just for brick-walled ancestors, but because they tell a part of our story not available through any other means.

Finding Your Ancestor’s Mitochondrial and Y-DNA

If you are the DNA tester for your brick-wall ancestor, then you’re golden, but chances are that you’re not.

If you’re searching for Y-DNA, and you don’t carry that Y-DNA yourself, you’ll need a male relative who carries that Y chromosome to test.

Males carry the Y-DNA of their direct patrilineal ancestors, shown in the image below on the left side in blue, plus the mitochondrial DNA (mtDNA) of their mother, shown with yellow hearts at far right.

At the 4th generation level, we have 4 Y-DNA lineages to collect (light blue, dark green, medium green, and teal), and a total of 8 mtDNA lineages.

Let’s say you’re searching for your father’s mother’s mother as your brick-wall ancestor.

Your father (and his siblings) carry the mtDNA of his mother, shown above in fuchsia, as do her grandchildren through her daughters. That’s why your father has a fuchsia heart. If close family members test, chances are you can arrange to manage their test or view their results. (Be sure they take the autosomal Family Finder test too. You’ll need that later.

If you don’t manage their test for them, you’ll need to ask to see their results to view matches and work with trees.

I have a family project at FamilyTreeDNA that I manage. I ask people who have tested for a particular ancestor to join that project so I can easily view their results while they continue to manage their test, and can select how much they want me to see or do.

FamilyTreeDNA is currently working on a multi-kit management feature that will address the challenge of sharing results.

But I Don’t Know of Any Cousins…

Let’s say you don’t know of and can’t readily identify anyone who descends from your ancestor appropriately.

If the ancestor you seek is a male, mitochondrial DNA is probably not going to help you because men don’t pass their mitochondrial DNA on to their descendants. In order to obtain a male ancestor’s mitochondrial DNA, you’d need to be able to identify a sister or someone known to descend from his mother (or sisters) through all females to the current generation. Needless to say, if you know who his mother is, you probably already know who he is.

If your brick wall is a female ancestor, your first order of business is to find someone who descends from her through all females to the current generation, where the tester can be male or female.

Why is this so important?

Mitochondrial DNA isn’t admixed with the father’s DNA, so it’s not divided in each generation. This means that mitochondrial DNA is the only direct line-of-sight we have that bypasses both changing surnames and genetic recombination for females.

Who Has Tested for Your Ancestor?

If you’re NOT the tester for your brick-walled ancestor or aren’t the curator of the test, your first step is to see if someone else has already tested.

This can sometimes be challenging.

It’s impossible to obtain mitochondrial DNA for an unknown ancestor if there are no known daughters, and for Y-DNA if there are no known sons. You may need to review genealogical resources to make sure you’ve identified all of that ancestor’s children.

Barring those scenarios, there are a surprising number of resources available to find descendants.

WikiTree

The first place I check to see if someone has already tested for a particular ancestor is WikiTree.

WikiTree is the one place where you find the ancestor along with the people who have taken DNA tests who descend from that ancestor. It’s invaluable.

Normally, you have to work with matches to identify your common ancestor. WikiTree works the other way around. Your starting place is with the ancestor.

You can’t Google your mystery ancestor’s name because if you knew their name, they wouldn’t be a mystery ancestor – but you can Google their spouse or a child.

I’m using an example from my own line because my mitochondrial DNA results are connected to her.

I’m Googling:

Barbara Mehlheimer born 1822 died 1906 in Indiana at WikiTree

Google was slightly confused but the results got me to where I needed to go.

Barbara Mehlheimer married George Drechsel and her daughter was Barbara Drechsel who married Jacob Kirsch.

First, check Barbara’s WikiTree profile card to confirm you’ve found the correct person.

Next, click on the DNA tab beneath her profile information (or just scroll down). She has four DNA Connections.

You can see that one person, me, who carries Barbara’s mitochondrial DNA has connected their DNA to Barbara’s profile. I did this by entering my DNA information on my WikiTree profile, then WikiTree connects my DNA haplogroup information from mother to mother to mother to Barbara and propagates my DNA haplogroup to her, her matrilineal ancestors, and their female descendants. If you click on the haplogroup, it takes you directly to that haplogroup in Discover.

Three people have connected their autosomal results to Barbara. This information can be very important, and not just for mitochondrial DNA. It allows us to identify autosomal testers we may match at different testing companies who descend from Barbara.

In your research journal, make notes of these names, testing companies, and kit numbers. Remember that this doesn’t mean the company noted is the only place someone has taken an autosomal DNA test. I’ve tested at all of the major companies, but only GEDmatch and FamilyTreeDNA are listed here.

For Y-DNA and mitochondrial DNA, the haplogroup is shown, although when testers receive a new Y-DNA or Mitotree haplogroup, they seldom think to revise it in WikiTree. This means their current haplogroup may be more specific and improved since the WikiTree information was entered.

Some people may have tested at different levels too. In this case, Buster Estes, who is now deceased, was one of the earliest testers, long before the Big Y tests were available. He only took a 25-marker test, so his haplogroup was predicted as R-M269. Garmon, on the other hand, was able to upgrade his Y-DNA test to the Big Y-700, and his haplogroup is much more refined at R-ZS3700. Their haplogroups don’t match exactly due to the levels at which they tested, but they also don’t preclude the two testers from belonging to the same genetic line.

This screenshot of Discover’s Compare function illustrates how important the Big Y-700 test is when compared to the STR test’s predicted haplogroups. The man who developed the mutation that defines R-ZS3700 lived about 1750 CE, and the man who developed R-M269 lived about 4450 BCE, or 6,450 years ago. That’s a big difference.

Using a combination of multiple testers and genealogy, we’ve identified the man who developed R-ZS3700 and passed it on to his sons. Moses Estes was born in 1711 in Virginia and all of his descendant testers carry R-ZS3700.

Now that’s extremely useful information, because we know that any man with haplogroup R-ZS3700 descends from Moses Estes in a direct paternal line, and any man whose haplogroup is not R-ZS3700 or doesn’t include R-ZS3700 upstream of his haplogroup does not descend from Moses Estes in that way.

Please add your DNA tests, including haplogroups and your kit number, to your profile at WikiTree so that the haplogroup information can be populated appropriately to your ancestors.

Searching for a Test Candidate Using Autosomal Descendants

When you’re searching for a testing candidate at WikiTree, you can click through to the tester’s profile and view exactly how they descend from the ancestor shown.

Let’s say that no one has linked a mitochondrial DNA test to the ancestor you’re searching for, but several people have linked autosomal tests to that ancestor’s profile card.

Click on the tester’s name and then on the DNA Ancestors tab to see how they descend from that ancestor. If you’re lucky, you’ll find someone in the autosomal list who is a mitochondrial DNA testing candidate.

If you’re looking for a Y-DNA tester, begin by looking for a male with the same surname as that ancestor. If you’re looking for a mitochondrial DNA tester, you’ll need to view each tester’s ancestors.

Regardless of whether they are a mitochondrial or Y-DNA testing candidate, you’ll identify your most recent common ancestor (MRCA) for each person, information that will become essential for the autosomal tools that we’ll be discussing in future articles.

In your research journal, I suggest that you record all of their descent information now, including their names, where they tested, your MRCA, kit numbers and any other relevant notes.

If you’d like to ask them to take a specific test, or if they already have and you’d like to know more, you can message WikiTree users by clicking on their profile, and then on the little envelope beside the profile manager’s name.

Finding Your Ancestor’s DNA Descendants at WikiTree

Let’s say that no one in the DNA list of people who have already taken tests descends from your ancestor matrilineally. Don’t worry, there are still more options!

At the top of the WikiTree page for that ancestor, click the down arrow, then on DNA.

The default tab shows the DNA Ancestors of the profile you’re viewing. You’ll see Y-DNA for males, and both mitochondrial and X-chromosome ancestors for everyone.

You may notice that there’s an ancestor listed for your brick wall ancestor. That’s wonderful, but don’t jump for joy quite yet. Remember, WikiTree is a one-world tree, and you need to verify the underlying genealogy in every tree here, and at every vendor.

Always confirm using multiple sources, meaning resources other than trees. The great thing about WikiTree is that there are often several sources listed in each person’s profile, and other resources that can help immensely. I love WikiTree, but I’m always skeptical of information in any tree, and I prove everything to my own satisfaction. I wrote several articles about that topic in the Genealogy Proof Series, here.

To find testers, you’ll need to view your ancestor’s DNA Descendants.

Click on the DNA Descendants tab.

The Mitochondrial DNA Descendants view shows potential candidates for mtDNA testing. Remember, in the current generation, males and females can both test so long as they descend from that ancestor through all females.

In the case of Barbara Mehlheimer Drechsel and her descendants, there are several males who are immediately eliminated because they’ve been deceased for more than a century, and several daughters who didn’t have children.

Not every person’s line on WikiTree has been added or developed. You can see that three daughters’ lines that might hold candidates don’t list all their children, and I still need to research two additional people. That means I still have five candidate lines to extend that have potential mtDNA testers.

So, in summary, if Barbara was the ancestor I was seeking:

  • One person has already tested
  • Three daughters don’t have their families extended.
  • Two have daughters that I need to research.

For both Y-DNA and mitochondrial DNA, I like to have at least two people who descend from different children of the ancestor, and whose tests match at a level that does not preclude that lineage. This helps confirm both the genetic line and the genealogy of both testers.

With male ancestors, having more than one tester for each line through different siblings is essential.

Kit Numbers, Earliest Known Ancestors and Google

When DNA kit numbers are included at WikiTree, you’ll want to Google to see if that kit number is shown in a public Group Project at FamilyTreeDNA where you may find more information.

The exact search string to use to find a specific kit at FamilyTreeDNA within projects is:

“9993” site:familytreedna.com

Replace 9993 with the kit number you’re interested in. You can also add the word “projects”, without quotes, to the end of that string to omit forums and limit the search to within projects. This string both focuses and limits the search, filtering out most noise.

By clicking on “read more,” you’re taken directly to the Estes Family Surname Project Y-DNA page.

The green haplogroups are SNP-confirmed, unlike the red predicted haplogroups from the lower-level 12, 25, 37, 67 or 111-marker tests. The R-ZS3700 haplogroup was obtained from the Big Y-700 test, so it is the most granular and specific. If this is your line, you’ve just found your ancestor’s haplogroup. It’s also possible that, by testing, you could receive an even more specific haplogroup.

Please note that haplogroup R-M269 is the most common haplogroup in Europe, and isn’t specific enough to use for anything other than very basic information. It can rule out two people with different base haplogroups, like haplogroup I or J, for example, as descending from a common patrilineal ancestor.

Project administrators are all volunteers, and each administrator groups their Group Project members differently, so take a few minutes to review the project pages. You may find additional testers who have joined this project who descend from your ancestors or your ancestral line.

You may also find other lines with the same surname and a substantially different haplogroup, which tells you that there are multiple genetic lines with the same surname. I have one example of this in the same county, at the same time, found in men by the same exact name – think John Smith. So frustrating. Without DNA testing, we would NEVER have sorted through those two same-name but completely different lines.

However, finding people who match your ancestor’s DNA but don’t have your earliest known ancestor (EKA) may be just the clue you need to knock down that brick wall. How are your ancestor and that other person’s EKA connected, and in what timeframe? Do they share a surname? A location? Are there other clues?

It’s unlikely that you’ll be able to use a kit number to Google unless you find one at WikiTree, but you can still search using the oldest name in that line that you know.

nicholas ewstas site:familytreedna.com

Replace the kit number with your EKA, in this case, “Nicholas Ewstas” in the search string, either with or without quotes. This takes you to the same page and any other projects that someone may have joined using exactly that earliest known ancestor’s name. Keep in mind that you’re only looking at their oldest ancestor, not every ancestor between them and their EKA. Your brick wall may lie someplace in there, which is why you need to check matches and view their trees.

Since women’s surnames change in every generation, they generally won’t be found in specific ancestral surname projects like men. This makes Googling using the ancestor’s name even more important.

catherine lejeune site:familytreedna.com

We don’t know who Catherine LeJeune’s mother is, so finding that someone has entered Catherine as their EKA may be critically important.

This is especially important for female brick-walled ancestors, since using this Google string with their daughters’ names may reveal someone else’s EKA in that genetic line within a project.

After clicking through to the project page, be sure to enlarge the page to display the full project, and use your browser search since partial results with predicted haplogroups may not be grouped with full mitochondrial sequence results.

Multiple people who descend from Catherine LeJeune have tested. The first six only took the partial test years ago. The bottom two testers took the full sequence test and have a new Mitotree haplogroup – U6a7a1a. We know that Catherine was born about 1633, in France, and we can see that other people have also tested and list different EKAs. Next, it’s time to research the other ancestors shown, or check WikiTree to see if any of these testers are listed there so you can contact them.

Now that you have found your ancestor’s haplogroup, you can use the free version of Discover to learn more. I wrote about using mitochondrial DNA and Discover in the article Mitochondrial DNA A-Z: A Step-by-Step Guide to Matches, Mitotree, and mtDNA Discover.

Now, let’s move to the DNA testing companies to see how we can find our ancestors’ Y-DNA, mitochondrial DNA, or testers, at 23andMe, FamilyTreeDNA, Ancestry, and MyHeritage.

At 23andMe

23andMe is not a genealogy company. That said, if you can figure out how people are related to you, you might be able to obtain a partial haplogroup for an ancestor. 23andMe shows both Y-DNA and mitochondrial DNA haplogroups to autosomal matches, but there is no Y-DNA or mitochondrial DNA matching, or associated tools.

23andMe caps matches without a subscription at only 1,500, and they don’t support trees, so I struggle to find useful haplogroups without an associated surname.

Browsing or searching your 1,500 allowed matches (you can have around 5,000 with a subscription) for a particular surname may provide you with an abbreviated haplogroup for both male and female ancestors.

Despite my best efforts, while my maternal grandfather’s mother is not unknown, nor are her ancestors for several generations reaching back into Germany, I’ve been unable to find her mitochondrial haplogroup. Evaline Miller (1857-1939) was born and died in Kosciusko County, Indiana, where she married Hiram Bauke Ferverda, an immigrant from the Netherlands.

Ferverda is an unusual surname, so let’s use it for our example. Thankfully, I’m not dealing with something like Smith.

I entered Ferverda in the 23andMe search bar and it shows four results, two of which are in the 2C-3C range, and one that’s further distant.

I already have the Ferverda Y-DNA, so I don’t need that, but I do need the mitochondrial DNA of Eva Miller Ferverda, and I really don’t want to sift through Miller surnames.

I know who Mr. Ferverda is on my match list, and which ancestor we share. His mitochondrial DNA is not Eva Miller’s.

Fortunately, I know who Eva’s parents were, as shown above on my MyHeritage tree, so I can search for Ferverda, Miller, Lentz, Ruhle, Wolflin, and Heubach, several of which are unusual. Reaching back into Germany is difficult.

It’s likely I match all four of those people at 23andMe through a common lineage that descends from either Hiram Ferverda, Eva Miller, or both. Let’s see what I can put together.

Emily is estimated to be a 2C2R. She is younger than I am based on the birth year she provided in her profile which I am not showing for privacy reasons. Emily also stated that her maternal grandmother was born in Warsaw, Kosciusko County, Indiana, and provided family surnames that include Ferverda, Miller, Glant, Zimmermann, and others.

Kosciusko County is where Evaline Miller lived with Hiram Ferverda, and their daughter, Margaret, married Chester Glant. Margaret Ferverda Glant’s daughter, Joyce, was born in Kosciusko County and married a Zimmerman.

But now, I was stuck. That’s all I had in my desktop genealogy software.

I shifted to Ancestry, where I discovered a death certificate and other information that provided what I needed to close the gap.

This information confirmed Emily’s statement that her maternal grandmother was born in Warsaw, Kosciusko County, Indiana.

Therefore, drum roll…Emily carries Eva’s mitochondrial DNA haplogroup, which is T2b.

Let’s move on to the other two matches, both of whom carry haplogroup T2b.

Ian’s maternal grandmother’s birthplace is Leesburg, Kosciusko County, Indiana, and his surnames include both Ferverda and Robison.

Eva Miller Ferverda’s daughter, Chloe Ferverda, married Rolland Robison and had a daughter, Charlotte, whose daughter married a man with Ian’s surname. Their information allowed me to connect the dots appropriately. Ian’s mitochondrial haplogroup is also T2b, which confirms Eva Miller’s mtDNA haplogroup through a second child.

Shirley, the third match who carries haplogroup T2b, also shows the surnames of Ferverda and Robison, and tracks back matrilineally to Eva Miller.

In spite of the many challenges at 23andMe, and thanks to the rare surname of Ferverda, I’ve identified Eva Miller’s partial haplogroup, but not her full haplogroup. A partial haplogroup is much better than nothing and gives me something to work with.

I checked at Ancestry, MyHeritage and FamilyTreeDNA to see if any of those three people have tested there and have trees. Indeed, Ian tested at FamilyTreeDNA and I had corresponded with him and made a note that he is a matrilineal descendant of Eva Miller Ferverda, but he has not taken a mitochondrial DNA test there.

We know that if Emily, Ian, Shirley, or another appropriately descended person were to take a full-sequence mitochondrial DNA test, we would learn a LOT more about Eva’s mitochondrial DNA. If I can’t locate someone who has already tested, I’ll reach out to these people at 23andMe and offer a scholarship for a full-sequence mtDNA test.

It’s ironic that at the most restricted and least likely testing company, I found three people descended from Eva Miller. Hope springs eternal.

Unfortunately, T2b was formed about 8450 years ago and is a very broad haplogroup made up of many subclades, but at least I have something now – and this partial haplogroup may be just the seed I need to lead to more.

Now, let’s move to FamilyTreeDNA and hope that someone there has already taken the mtFull test.

At FamilyTreeDNA

There are multiple ways to find the Y-DNA or mitochondrial DNA of your ancestors at FamilyTreeDNA.

Project Search

You can search for surname projects along with other types of projects.

On FamilyTreeDNA’s main page, without signing in, scroll all the way to the very bottom footer where you will see the Group Projects link.

If you’re searching for a surname, enter that surname in the search box.

The next screen shows projects that people with the Estes surname, including females, have joined. This includes all types of projects and does NOT mean that these projects are relevant to your line, but it does include two surname projects you may find useful.

Scrolling down shows you how many people with the surname of Estes have tested. Keep in mind that some will be females, some use married names, and sometimes people use an alias, so they aren’t included in this count.

Surname projects for females aren’t terribly helpful since the surname typically changes in each generation, at least in Western cultures.

You can also search for keywords, such as Acadian. If you know that ancestral line is Acadian, you may find clues there, including descendants of your brick-wall ancestor.

Group Project Time Tree

Many Group Projects at FamilyTreeDNA have enabled the Y-DNA Group Time Tree feature. When visiting the project, if the administrator has the Group Time Tree enabled, click on that link under the DNA results tab.

The Group Time Tree is a genetic tree of Y-DNA testers within that project based on the groups created by the project administrator.

The groups constructed by the administrator are shown at left, the Time Tree in the middle, and the testers with their EKAs and country of origin flags at right. I’ve added the red text to reflect the Estes genealogical lineage.

Based on the timeline at the top, you can see how closely these Y-DNA testers are related in time. Each haplogroup shown represents a different branching genetic lineage – breadcrumbs at work. If you are a genetic Estes male who descends from the Estes family that originated in Kent, England, and you take the Big Y-700 test, you’ll be a member of R-BY482 or its descendant haplogroups.

Keep in mind that not all testers join group projects, so it’s likely that there will be matches on your match list that aren’t here. Furthermore, only Big Y testers appear on any Time Tree.

The Group Time Tree is public, but when you sign in to your account and click on the Match Time Tree from your account, you’ll be able to view more, including testers’ trees and WikiTree connections if your matches have connected themselves to WikiTree.

I’ve converted the Estes genetic tree into a genealogical tree in a spreadsheet based on the trees of DNA matches. I’ve also included STR testers, because they are good candidates to upgrade to Big Y tests, and they are shown in the Estes Group Project. They can’t be included in the Time Trees because they don’t have the SNPs discovered with the Big Y tests. Please note that not all testers were included in this spreadsheet.

You can follow the paths of the various haplogroups. All of the red-background, black-outlined cells are Big Y-500 or Big Y-700 testers. The Big Y-500 was obsoleted several years ago in favor of the much more informative Big Y-700 test, which reveals additional haplogroups because it tests more of the Y chromosome. I’m still hoping that people will upgrade, although some testers are deceased and can’t.

The Big Y-500 tests with red stars are candidates to be upgraded to the Big Y-700 to potentially receive a more specific haplogroup. The balance of the tests in red cells are Big Y-700 tests, which identify several additional Estes haplogroup paths.

Let’s look at an example.

Beginning at the top, we know that R-BY482 is present in Nicholas Ewstas, born in 1496 in Kent, England, because all of his descendant testers carry that haplogroup too. Additionally, three generations later, in Silvester’s generation, he developed the additional mutation named R-BY490. We know it developed in Silvester’s generation for two reasons:

  • The descendants of Silvester’s brother, Robert, born in 1603, do NOT carry R-BY490. Robert’s son Matthew’s descendants only carry R-BY482.
  • The descendants of both of Silvester’s sons, Richard (pink column) and Abraham (the entire green row), all carry R-BY490.

All of the descendants of Silvester’s son, Abraham, born about 1647, the Virginia settler, who have taken the Big Y test carry R-BY490. Additionally, descendants of several of Abraham’s sons, color-coded columns beneath the green row, have developed additional haplogroups. Several more testers would likely have new haplogroups if they took the Big Y-700 test. A new haplogroup requires at least two men with the same unique mutation (breadcrumb), in addition to R-BY490 (in this case), to identify a specific lineage and assign it a new haplogroup name.

Abraham’s son, Moses Estes, born in 1711, is a good example. We know that Moses developed the mutation R-ZS3700 because four of his descendants have taken the Big Y-700 test and have that mutation that is not found in Moses’s brothers’ lines. All four Moses descendants carry R-ZS3700, and two, in the James Carroll Estes line, have developed an additional mutation, haplogroup R-BY154784.

Until Big Y testing became available, descendants of the R-BY154784 lineage didn’t know where they fit in the Estes tree, because the connecting genealogical records between Missouri, where their ancestors are found, and Virginia, where they came from, were missing.

Therefore, if you don’t carry the Estes Y-DNA, but you can find your ancestral line in projects, you can potentially do two things:

  1. Identify the specific lineage to which you belong, especially if you have access to your relative’s test results, including matches and trees.
  2. Without matches, you may still be able to identify at least some haplogroup levels, such as R-BY482 or R-BY490, which opens the door to:
    • Using autosomal results to find matches with Estes-specific haplogroups
    • Using Discover to utilize the dozen+ public reports available for everyone
    • Asking people to upgrade

While I’ve been using the Estes DNA results because it’s a project I administer and the one with which I’m the most familiar, this same approach works for mitochondrial DNA as well, especially if you can identify your ancestor’s DNA in a project.

Finding Projects in Discover

The public version of Discover provides surname and project searches as well, but works a little differently.

Select Group Project and enter the term you wish to search for.

Clicking on the project takes you directly to that project’s Group Time Tree where you can identify your ancestral line.

People who have tested at FamilyTreeDNA can join projects. Many projects accept autosomal testers who descend from that family line.

To join projects, sign in, then from your home page, click on “Group Projects” in the header, and make your selection.

Search for Surnames in Family Finder Autosomal Matches

Now that you’ve identified your ancestor’s haplogroup, you can use that information to find, rule in, or rule out various people in your Family Finder match list as your ancestors’ haplogroup carriers.

FamilyTreeDNA displays the haplogroups of your autosomal matches who have taken the:

The Family Finder test doesn’t test either the Y chromosome or mitochondria fully, but it target-tests a selected number of non-autosomal haplogroup-defining locations. The haplogroups that Family Finder identifies are typically midrange, meaning they are from roughly 2,000 to 5,000 years old. Furthermore, different tests on different chips at different times didn’t always test the same locations. This relatively new Family Finder haplogroup feature is free.

Uploaded DNA tests from other vendors may or may not receive a haplogroup, but regardless, it will NOT be displayed to their matches. Not all other vendors test or include Y-DNA or mtDNA SNP locations in their upload files, and your mileage may vary widely.

My cousin David has taken the mtFull test, so his mitochondrial haplogroup is the most refined possible, but his Y-DNA haplogroup of R-L151 was derived from his Family Finder test. Haplogroup R-L151 is about 5,000 years old. If I needed his haplogroup, it’s useful to rule out other major haplogroup branches that might be found in other men by the same surname. Plus, I can learn quite a bit from Discover.

Haplogroups are displayed in your Family Finder match list for everyone who has taken a Y-DNA or mtDNA test, but currently, only Y-DNA haplogroups are provided for Family Finder results. Midrange mtDNA haplogroups are planned for sometime in the future.

There are several methods to search for either a specific surname or haplogroup within Family Finder matches.

Let’s use my Ferverda/Miller/Lentz haplogroup T2b revealed at 23andMe. That haplogroup would almost assuredly be broken down further with full-sequence testing, and it might have been renamed as a different subgroup of haplogroup T in the new Mitotree.

Let’s begin with searching for haplogroup T2b.

The search bar allows users to select Name, Ancestral Surname, mtDNA Haplogroup or Y-DNA Haplogroup.

You’ll notice that there are a total of 59 results that include T2b as a part of the haplogroup. The mitochondrial lineage I’m seeking is my mother’s paternal grandmother, so the matches should be on my mother’s side, although there is no guarantee I don’t match someone autosomally on my father’s side too.

I checked the trees of all 59 people in the T2b category, and unfortunately, none descended from the line I need.

If you change search terms or categories, be sure to clear your filters.

Under the Filter option, you can filter for several options in addition to searching.

For our next example, I’ve selected both the Big Y-500 and Big Y-700 tests, and searched for Ferverda.

I already have the Ferverda Big Y-700 haplogroup, but if I didn’t, I would now!

Don’t forget that you can sort by any number of fields, and you can download your entire match list into a csv file. I find that easier because I can search, sort and filter at will.

Don’t forget to check back from time to time as more matches are added.

Utilizing Haplogroup Projects

Under the Group Projects header, or by Googling for a haplogroup T2 (or T, or T2b, etc.) at FamilyTreeDNA, you can view the haplogroup T2 project, and filter for haplogroup T2b or any subclade.

Be sure to expand the project’s page size to display the entire project. It defaults to displaying 25 rows at a time, but you can see the number of pages at the bottom of the page. I expanded the page size to 5000 so that I can use my browser search for known surnames in the mitochondrial line.

By using my browser search and searching for each known surname by generation, I searched for Ferverda, Miller, Lentz, Ruhle, Wolflin and Heubach.

I was VERY excited for a minute when I found a Lydia Lentz listed as a tester’s EKA.

Because the female’s surname changes in every generation, there’s only one family in this lineage that Lydia Lentz could have been a member of to represent the mitochondrial DNA of Eva Miller whose mother was Margaret Elizabeth Lentz.

So, the question is whether or not Lydia Lentz is the sister of Margaret Elizabeth Lentz.

Shifting to my desktop software, it’s easy to see that Jacob Lentz and Johanna Frederica Ruhle had four Lentz daughters who lived to marry and have children. None of those daughters were named Lydia, so the Lydia Lentz EKA in the haplogroup T2 project is not representative of Eva Miller’s mother and grandmother.

Margaret Elizabeth Lentz is Eva Miller’s mother, and I had already searched within the project for Miller. I added Yost, Gallagher, and Overlease to the browser search in the haplogroup T2 project with the hope that someone might have listed a woman with one of those surnames as their EKA, but no such luck.

Not everyone joins projects, or provides their earliest known ancestors, but I didn’t find the surnames of any of the females in my known line here.

Let’s see if Ancestry can help.

At Ancestry

Ancestry doesn’t do Y-DNA or mitochondrial DNA testing, so you won’t find your ancestors’ Y-DNA or mtDNA at Ancestry, but their trees can help you find testers.

Let’s shift to Louisa Drechsel, one of the daughters in the Mehlheimer/Drechsel line we were working with earlier that needed more research.

I looked at the hints for Emma Louisa Drechsel, who was always called Louise or Aunt Lou in my family, and discovered another Ancestry member with Emma in their tree.

I clicked through to the tree to discover that the tree’s home person does not descend from Barbara matrilineally, which means they are not a candidate for Barbara’s mitochondrial DNA.

I then clicked on the tree owner’s name to see whether they happen to be an autosomal DNA match to me. They are not. Without messaging them, there’s no way to know whether they have taken a DNA test, and there’s really no point since they are not a mitochondrial DNA candidate.

While I’m at Ancestry, I’m going to check ThruLines to see if anyone who is an autosomal DNA match to me also descends matrilineally from Barbara. There are no autosomal matches shown who have our common ancestor in their tree, and who are mitochondrial candidates.

Remember, a male between the ancestor and the testing candidate always blocks the mitochondrial DNA path.

These people are all autosomal DNA matches.

There may be descendants who either aren’t DNA matches or who haven’t tested who might be mitochondrial candidates. They can be located by checking Ancestry’s trees for our common ancestors and determining how the tree owner relates to that ancestor, if they do.

Compare Trees is New

Ancestry recently introduced “Compare trees”, a new beta feature. It may not be fully rolled out to everyone yet, and because it’s in beta, the feature may change.

To access this feature, go to your tree, not their profile card.

I clicked on Barbara Mehlheimer’s link in my tree, which displays this little mini-profile. Then click on “Compare trees” at the bottom.

Ancestry displays your tree, at right, and the other tree, at left. You can select another tree to compare at top right.

Ancestry’s comparison only shows a total of three generations – the selected person, their parents, and their children.

The person I actually want to follow is Louisa, but if you click on Louisa’s card here, it simply compares the two Louisas – it doesn’t shift down a generation.

This means that to follow more recent generations, you have to go back to your tree, select someone further down in the tree and repeat the process.

This process is cumbersome, but doable thanks to the new Compare Tree function. I’ll come back to this after checking the rest of the “easier to harvest” fruit from other resources. Remember to make notes in your research journal so you don’t forget where you left off – although trees are always changing.

MyHeritage has one of my favorite tools.

At MyHeritage

Recently, MyHeritage has begun providing midrange Y-DNA haplogroups for some of their DNA testers. If you’re one of the lucky testers, you can use the free Discover tool to learn about your haplogroup, but a haplogroup alone won’t help you much with genealogy. You need matching and advanced tools for that.

Unfortunately, you can’t see the haplogroups of your matches, so you can’t search or filter using that criterion. You can, however, ask any men with the surname you’re seeking if their haplogroup is displayed.

Cousin Finder

MyHeritage has an ingenious tool called Cousin Finder that I wrote about here. Cousin Finder helps you find cousins who share common ancestors with you, regardless of whether or not you are a DNA match.

MyHeritage found 531 people in their database that share ancestors according to both their and my trees.

This list of matches doesn’t page; it scrolls, so I made a spreadsheet of the people who are relevant to my search for my brick-walled ancestor. Scrolling becomes difficult and very slow as you proceed down the list. I didn’t want to have to do this twice.

You can improve performance by using the relationship side filter. Because your ancestors match, MyHeritage knows on which “side” of your tree your common ancestor is found.

At this point, I’m interested primarily in identifying Y-DNA or mitochondrial DNA candidates for a specific ancestor.

Using the Drechsel/Mehlheimer line as our example, I’ll search on my mother’s mother’s side.

We already met Patty at WikiTree, but let’s pretend we don’t know Patty. I can click on “View her tree” to see Patty’s whole tree, or I can click on “View Relationship,” which shows how we are both related to our common ancestor.

As we know, for mitochondrial DNA, any male in the line between the ancestor and the testing candidate blocks the mitochondrial DNA path. Patty inherited her mother’s mtDNA, not her father’s.

I didn’t forget about Eva Miller Ferverda either.

I searched for cousins who descended from my mother’s father’s side to find mtDNA candidates for Eva Miller and didn’t find any. But I did find an entirely unexpected bonus.

My mother’s father’s line shows all the connections on that side. While clicking through each one, I quite serendipitously discovered a mitochondrial DNA candidate for Eva Miller’s husband’s great-grandmother, Anna Elizabeth Jonker, AND, separately, a potential Camstra Y-DNA tester too. Oh, happy day!

It was only later, while working on my genealogy for Frederica Ruhle and hoping to discover where she actually lived in Pennsylvania, that I discovered that MyHeritage has put a Cousin Finder link in each ancestor’s profile.

Who doesn’t love a pleasant surprise?!

You no longer need to sift through all of your cousins on a particular side, but remember, had I not done that, I wouldn’t have found either the mitochondrial descendant of Anna Elizabeth Jonker nor the Camstra Y-DNA candidate.

At FamilySearch

FamilySearch is more challenging and is best for fleshing out trees where not much research has been done. Remember that FamilySearch has access to records that are not available at either Ancestry or MyHeritage.

FamilySearch is a one-world tree. Like all trees, it’s subject to errors, so caution is always advised.

At FamilySearch, from your profile card in the tree, locate the ancestor whose Y-DNA or mtDNA you seek.

Then click on that person. Their profile card will pop up. Click on “Tree,” then, at the top right, select Portrait.

Now you can expand their children downward. Note that the little “two people” in the top left corner of the profile card means there are multiple spouses. The only way to view all of the children is to click on that person’s placard, then select the alternate spouse.

Living people have no placeholders on this tree.

You can contact contributors who provided information on a profile in the tree.

Click on the source provider’s name to see if they are related, and click on the little tree icon to see how.

However, once a year, there’s a great way to contact interested descendants.

Relatives at RootsTech

RootsTech is the largest genealogy conference in the world, and it’s sponsored by FamilySearch.

About six weeks before RootsTech takes place each year, and for about a month after, you can participate in Relatives at RootsTech.

During that time, you can select an ancestor and see which other people who have signed up for RootsTech also descend from that ancestor. I wrote about how to do that in the article, Relatives at RootsTech Reveals Cousins and Provides DNA Candidates. I almost always find someone who descends from an ancestor whose Y-DNA or mtDNA I need for my tree.

It’s a wonderful opportunity to meet new cousins and collaborate.

At GEDmatch

GEDmatch is an autosomal DNA upload site that offers a variety of matching and display options. While they don’t attempt to calculate a haplogroup, uploaders can enter their mtDNA and Y-DNA haplogroups, if known.

GEDmatch isn’t normally a resource we think of for either Y-DNA or mtDNA, but it can be useful under some circumstances.

In the One-To-Many limited free version and the Tier 1 subscription model, you can view haplogroups if someone has entered their haplogroup name, but you can’t filter without the Tier 1 version.

I filtered for haplogroup T2b and found one person in the match list with haplogroup T2b4. I then viewed the GEDCOM that this person has also uploaded, but they do not descend from Eva Miller Ferverda’s line.

GEDmatch isn’t built for haplogroups, but sometimes, if you have a known haplogroup that isn’t terribly common, you can catch a lucky break there.

Where AM I?

OK, so where am I in all of this?

I feel like I’ve searched the corners of the earth!

I’ve primarily used two examples.

  • My own mtDNA line which is the Drechsel/Mehlheimer line that I chose because it’s a great example that I knew well.

If I had actually been searching for a testing candidate, we would easily have eliminated several possibilities. Five female lines remained as possibilities that need additional research, plus my own test if someone were actually searching.

  • Then there was Eva Miller Ferverda (1857-1939), whose partial haplogroup, T2b, was discovered at 23andMe in three matches. I was able to reconstruct their trees, confirming that this was her line, but I was unable to find any testing candidates elsewhere.

Each of the DNA testing and genealogy vendors provides a way to communicate with other users of their platform.

  • At both 23andMe and MyHeritage, you can message through their platform.
  • At FamilyTreeDNA and GEDmatch, you can email your matches.
  • At WikiTree, you send an email through their platform to the profile card manager.
  • At FamilySearch, you cannot see placeholder cards for living people, so you need to check to see if people making changes to that ancestor’s profile are related. Then check their children closest to the present day for the same information. You can message through the FamilySearch platform.
  • During Relatives at RootsTech, you can message your cousins through their platform. The great thing about these folks is that you know they are interested and engaged, because they’ve just signed up for RootsTech.

Communicating With Testing Candidates

I’m fortunate that there are three mitochondrial descendants of Eva Miller Ferverda at 23andMe, one of whom is also at FamilyTreeDNA. I will message or email all three of them individually with a short, customized message that contains:

  • How I am related to our common ancestor.
  • A question about whether they have taken the mtFull test, or any test, at FamilyTreeDNA. If they have taken any test there, it’s easy to upgrade.
  • A sentence about how FamilyTreeDNA was the original genetic genealogy founder of this industry and the only company to offer the full mtDNA and Y-DNA tests.
  • Why they can benefit from taking the mtFull test and how it can help us learn more about our common ancestor.
  • An offer for a full-sequence mitochondrial DNA testing scholarship if they have not already taken that test.
  • I ask if they are interested and provide my email in case they have questions or want to discuss further.

Depending on how much space I have for the message, there are two articles I often provide links to in case they are unfamiliar with either Y-DNA or mtDNA testing.

  1. 4 Kinds of DNA for Genetic Genealogy is a very basic article for people who might be unaware that there is any type of DNA testing other than autosomal. This is often the case with Ancestry.
  2. The article Mitochondrial DNA A-Z: A Step-by-Step Guide to Matches, Mitotree, and mtDNA Discover is an in-depth article about using mtDNA. This is a wonderfully educational how-to article, but I always hesitate before sending this one because I don’t want their eyes to glaze over.

Scholarships

I gladly and eagerly offer scholarships for both Y-DNA and mtDNA testers from lines I need to represent my ancestors.

I equate scholarships to finding a rare out-of-print book about that exact family line, with only one or two copies still in existence, and only one accessible in a rare book shop in Podunk, Idaho. I would book a flight tomorrow at 5 AM to go and pick it up in person even if I had to eat beans and hot dogs for the next six months to pay for it. If you know me, you know I’m not kidding! I’ve gone on many wonderful road trips to meet with and collect DNA samples from cousins.

A Y-DNA or mtDNA test doesn’t cost nearly as much as that excursion and is even more reliable, because we know the DNA results are accurate – assuming the tester’s genealogy is accurate, which you should verify, and no undocumented adoptions or broken lineages have occurred.

Good luck on your treasure hunt!

FOCUS: Step 1 – Seven Solutions for DNA Matches with Absent or Shrunken Trees

Posted on by
6

This is the second article in the FOCUS series.

You can read the first article, FOCUS – A New Series Focused on Breaking Down Brick Walls, here.

DNA matches without trees, or bare-bones shrunken trees, can be a significant roadblock whether you’re looking at autosomal, Y-DNA, or mitochondrial DNA matches. To help resolve that issue, I’ve listed seven ways you can create or expand those trees. Not every methodology works every time, but none will work if you don’t invest the effort to try them.

I’ll probably say this in every article because it bears repeating. Everything we are working with is a hint. Breadcrumbs along the way. Sometimes they lead to the next wonderful breadcrumb. Sometimes to a dead end. Sometimes they look like useful breadcrumbs, but they are red herrings and not relevant. And sometimes they are simply wrong. Do not throw the baby out with the bathwater. Also, do not think every hint is accurate, because they aren’t, and many rely upon other people.

Our goal in the FOCUS series is to accrue evidence from multiple sources, tools and methodologies that leads us to our ancestor. So let’s start with trees.

Trees, Trees, But Not Everywhere

DNA testing relies on trees to identify our common ancestors, at least with matches beyond the closest generation or two.

This is true at all vendors, which is why all of the main vendors, except 23andMe, integrate with or provide trees as part of their platform.

Because we need to work with trees for all types of DNA testing and matching, I’m going to share various ways to overcome partial trees or even no tree at all. I’m intentionally using examples from multiple vendors throughout this series.

23andMe is omitted in this article because they don’t support trees, although testers can include a link to a tree elsewhere.

GEDmatch is omitted in this article because they are not a testing company. They are a DNA upload and matching site, so everyone at GEDmatch has tested elsewhere and probably has a tree there. You can upload a GEDCOM file to GEDmatch, though, so it never hurts to check and see if your match is there too.

Some of these techniques are vendor specific, and others can be applied broadly.

What Is a Shrunken Tree?

A shrunken tree is a small tree in which your DNA match has included only a few people. Small or missing trees tend to frustrate genealogists – a lot. I remind myself that these folks maybe seeking their family or new genealogists, trying to piece their tree together themselves.

This is a tree provided by one of my matches. Their mother is deceased, but it’s recent enough that I’ve chosen to obfuscate her name as well, and it’s not relevant to the next steps.

There’s not a lot to work with here, but as it turns out, there’s enough.

Based on this tree, we have no idea where in their tree our Most Recent Common Ancestor (MRCA) is found, so let’s look at a few ways to indirectly expand their tree in order to find our common ancestor.

Step 1 – Check Your Own Tree

I know this sounds like a “duh” moment, but always remember to check your own tree to see if you’ve expanded that branch to include your match’a ancestors and completely forgotten about it. I maintain my primary tree on my computer with lots of notes and information that I’m not comfortable uploading to a public space. I maintain smaller public trees with a couple thousand people at both Ancestry and MyHeritage, along with a link to my ancestors at WikiTree.

If your match is a female, they may be using a married surname, so always keep that in mind. I try their complete name first. Then I search for their surname to see if it’s a “married-in” name – and cross my fingers that it’s not Smith. If they have any ancestors in their tree, I try their oldest generation next.

Step 2 – Reach Out to Your Match

Every vendor provides some way of communicating with your matches. You can either message or email, depending on the vendor, and your match may be very willing to share more about their genealogy. They may have a better tree elsewhere that they will share with you, or may know more than is in their tree.

An Ancestry survey showed that about 53% of Americans can’t name all four grandparents, and only 47% can correctly name all four. Only 4% can name all eight great-grandparents. In the Rolland tree, the tester knew more about their mother’s side, and only knew the first name of their paternal grandmother.

So while shrunken trees are exasperating, they are probably more normal that we think, and we all have to start someplace. Your match might well appreciate some help.

Step 3 – Check Other DNA Testing Sites

If your match has a real name (meaning not just initials or something indecipherable), such as Heather Jacobs (made-up name), who is predicted to be your third cousin and shares 100 cM of (unweighted) DNA at one vendor, sign on to your accounts at the other vendors and see if Heather is a match there.

You’re looking for a Heather, or maybe HJacobs or something similar, who’s approximately a 3C with roughly the same amount of shared DNA. The exact relationship prediction may not match, but it should be close, and the amount of shared DNA may not be identical either. If it varies substantially, it may not be the same person, so exercise care.

Every vendor provides the ability to search for matches by name, and if you can’t find them by name, begin paging until you reach matches at the approximate predicted relationship level. In Heather’s case, that’s third cousins. Beyond third cousins, this paging technique quickly becomes too laborious.

At Ancestry

Only one vendor, Ancestry, “downweights” your DNA with your matches, meaning that they may remove some amount of DNA that they consider “too matchy.” In my case, this is often DNA from my Acadian lines, which collectively forms pileup regions. This does NOT mean those aren’t useful, but that’s not relevant for this discussion other than to alert you that you need to check both the assigned amount of DNA and your unweighted shared DNA with a match when you’re trying to verify that the match is the same person at two vendors.

Assuming you find “HeatherJ” at Ancestry, you’ll want to verify that it’s the same person as Heather Jacobs at the other vendor.

Is your amount of shared DNA roughly the same?

Click on the relationship link to view the amount of unweighted DNA. In this case, weighted and unweighted is the same, and Heather Jacobs matches you with 100 cM at the other vendor.

Heather has a public tree here, and it’s the same size. It’s probably the same person, but check anyway.

Heather’s tree at Ancestry is exactly the same as it was at the other vendor, so this confirms it’s the same person.

There’s an important hint here, and let me emphasize the word HINT.

While Heather’s actual 15-person tree does NOT extend to our common ancestor, Ancestry has pieced together other trees that include and extend beyond her ancestors to show my (purported) common ancestor with Heather. Click on Common Ancestor, which takes you to ThruLines.

This new version of ThruLines has now replaced the older version. Unfortunately it does not show Heather’s path back to our common ancestor, Hiram Bauke Ferverda.

Click on “View all ancestors” in the upper left-hand corner.

Click on any image to enlarge

After clicking on “View all ancestors,” click on Hiram Bauke Ferverda to see the DNA matches who descend from him. Despite what Ancestry provided under my “Common ancestor” with Heather, she isn’t shown anyplace here. This could be a bug, given that I later confirmed this common ancestor using other techniques.

Regardless of the problem, this IS a hint, so don’t disregard it entirely. Just keep your “skeptic” hat handy and wear it liberally. You’ll need to use Ancestry searches and hints, including possibly Quick and Dirty Trees, to piece together the possibilities.

Make a note on Heather’s match at Ancestry so that you know what you found this time through. We’re not done with Heather. Move on to another vendor to see if Heather has tested and has a better tree elsewhere. We’re gathering evidence.

At MyHeritage

Heather is not at MyHeritage, so I’ll use a different example.

Let’s look for Cathy, a 3C match who has no tree at another vendor. I found her at MyHeritage with the same first and last name and approximately the same amount of shared DNA, so I’m confident it’s the same person.

Fortunately, at MyHeritage, Cathy has a tree, which is the first step, of course, but no common ancestor is shown in her tree.

MyHeritage has a wonderful feature called Theory of Family Relativity which are often based on “Smart Matches.” Click on “View theory.”

MyHeritage has found five possible paths to a common ancestor based on multiple documents and trees. In this case, Surrilda Claxton in my tree is the same person as Surelda Clarkson in Cathy’s tree, and MyHeritage made that connection correctly.

I confirmed this Theory at MyHeritage as accurate, and now I know how Cathy at the other vendor with no tree is related to me. I made a note about Cathy at MyHeritage on my match with Cathy at the other vendor too about our common ancestor AND where Cathy’s tree can be found. Add Cathy to her proper place in your trees.

Step 4 – Sleuth at the Same Vendor

At FamilyTreeDNA, when I find a match with no tree, I do two things.

Looking at Patricia’s profile, I immediately see that she has been assigned to the maternal side of my tree. I’ve linked other known matches which allows FamilyTreeDNA to use triangulation to assign Patricia to the proper side.

Then, I notice that even though Patricia doesn’t have a tree, she has provided her ancestral surnames.

Clicking on “View Details,” I can see if any of them match my surnames, or I can view all of her surnames.

Given that this is my mother’s side, these shared surnames give me an idea of a shared lineage.

Next, look for your closest shared match WITH a tree. Clicking on the two little people at far right displays your shared matches which are labeled “in common with.”

I share 122 matches in common with with Patricia, and our closest shared match, other than my mother who is not shown here, is Dennis. Dennis happens to be a known relative, which is why he already has a note.

But for purposes of this exercise, let’s say that I haven’t already figured out how Dennis and I are related. Viewing Dennis’s tree, I see that our common ancestors are Anthony (Antoine) Lore and Rachel Levina Hill. Hmmm, Hill is on Patricia’s list of surnames.

Sleuthing at the same vendor is MUCH EASIER when your matches have at least a couple of generations in a small tree. Having no tree is the most difficult situation at every vendor, but there are multiple ways to begin building a tree for your DNA match, or to expand a shrunken tree.

Step 5 – Google Is Your Friend

Google is your friend. Google cannot reach behind paywalled sites, so you won’t find records other than records from free indexes at Ancestry or MyHeritage in Google searches, but you will find information about people from other genealogy sites.

Let’s go back to Rolland Robison who died in 1963 and his wife, Chloe. And let’s also consider that his surname is often spelled RobiNson. We know from our match’s tree that Rolland’s wife’s first name is Chloe.

Look closely at the search box in the image below. By structuring the query as “rolland robison died 1963 wife chloe”, we combine a full name, a specific vital event year, and a spouse’s first name. This gives Google just enough precise detail to hopefully filter out (most) noise.

That’s interesting. It looks like Rolland can be spelled two ways too.

Not only is there an article (yes, I wrote about this previously), BUT there’s also an obituary and estate distribution in a local newspaper that I have never seen before.

Rolland’s wife’s birth surname is given in his obituary, even though her first name is misspelled. This is the link I need to establish our common ancestor, because Chloe is my grandfather’s sister.

Google can provide you with important links to information and articles that are not yet in genealogical databases, such as:

  • Facebook accounts for individuals: Useful for finding the tester, relatives or family connections.
  • Facebook groups and pages: Forums that contain local historical information and shared community memories.
  • LinkedIn & Instagram accounts: Social footprints that often reveal professional histories, geographic locations, and birth surnames.
  • Mentions elsewhere: Local newspaper archives, digital press releases, and published legal notices regarding estate partitions or land records.
  • Obituaries: Printed family notices that explicitly list surviving family names and relationships along with the Legacy.com tribute archives.
  • Public websites & genealogy blogs: Independent sites where genealogists sometimes publish deep-dive ancestral lineages. Always verify.

Google also provides an easy way to find free resources in public databases without having to search each one individually, including:

  • Collaborative family trees: WikiTree, FamilySearch, and Geni trees.
  • Cemetery registries: FindAGrave and BillionGraves.
  • Digital libraries: Internet Archive and Google Books, which hold a vast assortment of historical information like out-of-print town and county histories.
  • Open-Access portals: The Library of Congress (LOC) and the Digital Public Library of America (DPLA), which pulls photos, maps, and civic documents from libraries across the US.
  • Volunteer projects: Regional repositories like GenWeb.
  • Directories: Local alumni directories and digitized historical yearbooks.

Pro Tip: Resurrecting Old RootsWeb and Genealogy.com Breadcrumbs

RootsWeb was a wonderful resource for genealogists until Ancestry began systematically dismantling it in 2023.

While Google is fantastic at finding obscure text, it will occasionally point you to an old, broken RootsWeb link. Because Ancestry has frozen or removed much of the old platform, don’t let that 404 error stop you in your tracks. Copy the dead URL from Google and paste it into the Internet Archive Wayback Machine where you can sometimes resurrect the exact information you need!

The same methodology applies to the old message board, Genealogy.com.

Step 6 – Search Old Emails and Files On Your Own Computer

I know this probably sounds either ridiculous or incredibly obvious, but if you’re a typical genealogist, you probably have a quarter century of emails on your computer, not to mention reams of photos that you saved because someone gave them to you and you “might need them someday.”

I’ve never thought of myself as the family archivist, but I clearly must be, which is another name for the family packrat. Long live the packrats.

I’ve learned that I need to search all of my email folders for the names in someone’s shrunken tree. I’ve been shocked at what I’ve found there.

Don’t just search for full names. For example, Rolland Robison or Chloe Ferverda. Search for the names individually too. So, Rolland, Roland, Robison, Robinson, and Chloe. I didn’t know Chloe was a Ferverda yet when I was initially searching for her identity.

A middle-of-the-night insomnia-induced epiphany struck – “search your emails.” Who needs sleep? It’s overrated! I hopped right up, searched my emails and my computer and found even more.

As it turns out, I attended a Ferverda family reunion in 2010 where I only knew two people. Thankfully, cousin Cheryl thought to invite me, because someone brought an old photo album AND an old Ferverda family Bible. I took photos of everything in the album even though I had no idea who most of those people were and neither did the album’s owner.

Many photos had no surnames at all, or they were recorded as Mr. and Mrs. SoAndSo.

Here are “Chloe and Rolland” as they were named in the photo, with no last name or additional information.

Here are Mr and Mrs. Rolland Vincent Robison. I carelessly saved this one as Rolland RobiNson. My bad.

A search for just “Rolland” found both, which is exactly why you need to search creatively.

Finding those initially still wouldn’t have told me who they were, but I would have at least had some family context, given that a Ferverda descendant brought the album to the Ferverda reunion.

However, this article about Rolland and Chloe’s 50th wedding anniversary from that same album would have provided that missing context.

My emails revealed now-deceased cousin Cheryl referring to Aunt Chloey, but with nothing else to identify her. A search for simply “Chloe” found Cheryl’s emails.

More tidbits of evidence.

I did a very poor job of saving these images with useful names because they weren’t relevant at the time, although I did store them in a “Ferverda Reunion” folder. Now, I’m going to attach them to Chloe and Rolland’s profiles in my tree at both Ancestry and MyHeritage to make sure they don’t disappear forever.

I’m also going to send them to my match with the abbreviated tree. As Rolland and Chloe’s grandchild, if they don’t have these pictures, I’m positive they will want them.

I’m sure you’ve noticed that I got VERY squirreled during this process, but utilizing all of our resources is exactly how we make discoveries – and sometimes that includes chasing squirrels.

This is also why our research journals are important – so we don’t chase the same squirrel over and over.

Step 7 – Quick and Dirty Trees

I used the Robison example in an earlier article discussing how to build a “quick and dirty” tree. I use quick and dirty trees often because it’s the easiest way to keep track of informational tidbits from different places, including multiple vendors, during the research process.

I’ll say it again here. Quick and dirty trees aren’t meant to be public. They aren’t gospel. They are a structure for you to work through the various hints provided and to evaluate them to see if they are of sufficient quality for you to identify a common ancestor with a DNA tester who provided a minimal tree.

You can read about these investigative workbenches in the article, What is a Quick and Dirty Tree, and When Might I Need One?

What’s Next?

Have you decided which of your brick walls you’re going to focus on? Last week’s article discussed some of the criteria you might want to consider and how to prepare.

Select your ancestor, because next week, we’re going to begin using a variety of tools and techniques to track that ancestor. Bit by bit, we’re going to gather evidence that will hopefully lead to a breakthrough.

The New Family Finder NGS Test Results, Comparison, and Preparation

Posted on by
19

This article is focused on two things.

  1. Comparison of my new NGS and the earlier Family Finder tests
  2. How to prepare for yours if you’ve ordered the upgrade

I compared my results from my older Family Finder test with my new NGS Family Finder test results. As an early beta tester, I have two separate tests, a strategy that is not recommended because it causes duplicate matches for people within the database. Additionally, multiple kits for one person doubles the results and could skew future ethnicity research for myOrigins.

Therefore, FamilyTreeDNA has announced very attractively priced upgrades at $29 for both:

  • People who have taken Family Finder test directly at FamilyTreeDNA
  • People who have uploaded their DNA files into Family Finder from other companies

After seeing my comparison, you may want to compare your own results when they arrive, so I’ve documented that process. Warning: this took between 4 and five days because I was working with a spreadsheet with more than 15,000 rows, and I had to write scripts to perform multiple functions. It was NOT fun and I do not recommend it.

Personally, had I known then what I know now about how reliable the new NGS test is, I wouldn’t have bothered with the comparison. However, I would have downloaded my original match list for posterity, just in case.

If you purchase an upgrade to the new NGS Family Finder, your new test results will replace your older Family Finder test results, but will preserve important account features such as linked matches, any notes you have taken, and more. That’s another reason to upgrade rather than order a separate new test. They’ve done the heavy lifting, not to mention that you’ll save about $50 when compared to the price of a new test.

Why is the New NGS Family Finder Test Better?

The new NGS test holds immense promise for the future. This includes better matching, beginning now. Essentially, FamilyTreeDNA is skating to where the puck is going to be (hockey analogy) and preparing for future tools. That future is not far away!

An amazing new set of tools is goaled for release around the end of the year. And I do mean amazing. They are being beta-tested internally now.

Dave Vance spoke about the new Family Finder NGS test at the ECGGC conference in late August, which you can view through the end of 2026 if you register for the virtual  conference, here, and watch the recorded sessions. You’re looking for the DNA Academy on Saturday evening. I can’t share specific preview slides with you as they are noted in his presentation as “not for distribution,” so my pen is capped for now.

All I can say is that after seeing what’s in store, people were literally throwing their billfold at the folks at the FamilyTreeDNA booth – and I do mean literally. “Here – take my money, please!” as the billfold went sailing. We all had a good laugh, but he was serious.

One presenter (not me, just in case you are wondering) left her credit card and a list of tests to upgrade while she was presenting.

They ran out of swab kits at the conference shortly after Dave’s presentation about what the future holds.

Additionally, you will also be treated to THE absolute best presentation I’ve ever seen about what NGS testing is, how it works, and how it compares to traditional tests, low-pass whole-genome tests, and medical-grade whole-genome tests.

You’ll be a passenger on the Genome Valley train, so climb aboard!

So, without spilling any beans, what’s so great about the NGS test?

To begin with, the older Family Finder tests won’t be able to provide everything the new NGS test will be able to offer – and those completely new tools are in active development today.

Why?

The NGS test targets over 280 million base pairs, up from the currently available 700,000.

That’s more than 400 TIMES the coverage.

This increases coverage in the human genome from about .02% to about 9%.

To quote FamilyTreeDNA, “This change allows us to deliver more precise autosomal results today while creating a strong foundation for future reports and tools.”

You can read the FamilyTreeDNA FAQ here.

Before we move on to the comparison, let’s talk for a minute about test types and uploads from other vendors.

Tests and Uploads

All new Family Finder tests purchased at FamilyTreeDNA since March 2, 2026 have been tested using Next Generation Sequencing (NGS), so the following matrix does not apply to those tests. Those tests don’t need to be upgraded.

If you sign on to your account, on the Family Ancestry dashboard, and see that your NGS button is grey, then you have not upgraded. Click on that grey button to read more and to upgrade. Right now the upgrade is $29, but I don’t know if that is a promotional price or permanent.

If you tested at FamilyTreeDNA prior to March 2, 2026, or uploaded a DNA file from another vendor, your test will fall into one of the following upgrade path categories.

Tested at FamilyTreeDNA before March 2, 2026 Uploaded and purchased the Unlock Uploaded but did not purchase the Unlock
Upgrade Path Can use sample stored in lab if enough DNA remains* If you purchased any other type of test at FamilyTreeDNA, they will use DNA stored in the lab if enough remains. Otherwise, you will be sent swabs. If you purchased any other type of test at FamilyTreeDNA, they will use DNA stored in the lab if enough remains. Otherwise, you will be sent swabs.
New Swabs* If needed, they will notify you Yes, if needed, will notify or send swabs if you have not taken a direct test at FamilyTreeDNA Yes, if needed, will notify or send swabs if you have not taken a direct test at FamilyTreeDNA
NGS Results Will replace existing results Will replace existing results Will replace existing results

*You will be notified if enough DNA does not remain, and you will be sent new swabs. Be sure your address is current.

One of the reasons the NGS test performs better, even with existing matches from earlier tests, is because less imputation is involved. Let’s talk for a minute about imputation and how it works.

The Concept of Imputation

Most vendors change chips internally from time to time, and FamilyTreeDNA is no different. The difference this time is that the new NGS test covers exponentially more DNA than any earlier test, and all earlier tests combined. This means more than 400 times greater coverage, which in turn means less imputation is needed to compensate for the inevitable no-reads and to be compatible with files that tested different DNA locations.

Imputation is also used when comparing DNA files between vendors who don’t test the same locations.

Click to enlarge any image

Here’s an illustration of the concept of how imputation works.

All of the FamilyTreeDNA chip versions over the years have included about 700,000 locations, as have most other vendors. But the locations tested are not universally the same.

In our simplified concept example, FamilyTreeDNA’s tested “locations” are shown with blue cells.

The total of 20 squares shows the maximum amount of DNA tested by any of the three vendors shown, combined.

Green Vendor 1 in our illustration tests the same amount of DNA that FamilyTreeDNA tests, 12 squares, but some locations are the same and some are different. Of the 12 colored squares for both vendors, seven are the same locations, and five are not. The locations that are the same can be compared directly, but the locations that are different have to undergo special handling called imputation.

Looking at any location in our DNA, one of four nucleotides, or letters, can be present: T, A, C or G on each strand of our chromosomes, although we are only looking at one strand in our example.

Using a very simplified model of imputation, think of imputation as “filling in the blanks” using clues from surrounding letters – kind of like a crossword puzzle.

When two vendors’ data doesn’t overlap, imputation is used to fill in the blanks, as accurately as possible, for the missing data.

Using a word analogy, for vendors one and two only, we see that blue location three has no Family Finder data, where green Vendor 1 does, and the same with location five. If blue locations two and four are C and T, and three has to make a word, then there are few options. In this case, let’s say it’s cat, and location five is imputed to an A too.

Now moving to green Vendor 1, their locations two and five need to be imputed. Moving away from the word analogy, let’s look to the human genome, and let’s say that most of the time, location two is a C if location one and three are Gs. So green location two is imputed to C.

If there’s not enough quality surrounding data, imputation can’t be performed reliably. Hence, location six is still in limbo here.

You can see that in our scenario, location three is the only mismatch, out of three imputed locations. Does location three mismatch because imputation was wrong? We don’t know. Do locations two and five match because imputation was wrong? We don’t know.

All things considered, imputation is based on the science of probability, and is usually relatively reliable, but it’s still not the same as comparing actual data. The more locations that have to be imputed, and the longer the stretch, the greater the possibility of error. Every vendor implements imputation differently too. Even vendors who don’t and have never accepted uploads still use imputation internally to equalize their own legacy files from earlier test versions.

Stepping back once again to compare the four vendors, you’ll notice that pink Vendor 3 only tested half as much DNA as the blue Family Finder test and green Vendor 1, and again, not all of the same locations. That’s exactly what happened with one of the vendors last December – they dropped the number of DNA locations tested to about 400,000 from about 700,000. In our example, you can see how much would have to be imputed. Locations 11, 15, 19 and 20 can’t be imputed for the pink vendor’s file because there’s no surrounding DNA. Location 17 can’t be imputed for the green vendor for the same reason.

When vendors impute to match multiple versions of other vendors’ uploaded files, it can quickly become messy.

The answer, of course, is a “supertest,” which tests all of the locations that overlap everyone, including that vendor’s own earlier tests.

Welcome to Family Finder NGS, shown in orange at the bottom of our example comparison.

As you can see, the orange NGS test covers all of the locations tested by all of the other tests.

NGS is targeted testing for a specific set of locations that are known to undergo mutations in the human genome and provides extremely high-quality results. Imputation for the NGS file is rarely necessary, although imputation for the other vendors’ and earlier file versions is still required for them to match to each other.

This is exactly why the upgrade is recommended, and why there’s no benefit to retaining your old test. The NGS test tests far more data and provides much more reliable matching.

NGS is the great equalizer.

NGS Test Comparison Process

I took my NGS test during the initial R&D development and testing phase, so my original Family Finder test was not upgraded. This afforded me the opportunity to compare the two results.

I downloaded the match files for both of my tests, the original Family Finder and the new NGS Family Finder test, color-coded the background of the cells, not the text inside the cells, and dropped them into a single combined spreadsheet.

It doesn’t matter what colors you choose, but be sure you can easily see the difference. I used apricot for the original Family Finder test matches and light purple for the new NGS test.

As we walk through these results together, you’ll notice that I continue to refer to them by color. In part, that’s so I can maintain my own sanity as I compare results. When I write these types of articles, I have to check and recheck results.

When the same person showed as a match to both tests (meaning they had both an apricot and purple row), I calculated the difference in matching amounts of DNA (cMs) between the match’s results on both tests. I added several calculation columns, which are not shown above.

I’ll tell you, this was not a trivial exercise. It was painful and I really don’t recommend it.

Let’s take a look at the results.

Total Matches

I have some matches with the new NGS test that I do not have with the legacy Family Finder, and I have some matches on the older test that are no longer present on the NGS test.

  Old Family Finder (apricot) NGS Family Finder (purple) Difference
Total Matches 9014 7719 1,295
Maternal 1665 Not linked
Paternal 3783 Not linked
X-Matches 2198 1849 349

I have not yet linked the same matches in my NGS test, so I can’t compare the number of maternal and paternal matches. Fortunately, when you upgrade an existing test, FamilyTreeDNA preserves your linked matches, so you won’t need to relink.

Relationship Estimates

  Old Family Finder (apricot) NGS Family Finder (purple)
1st-2nd cousins, Great/Half Uncle/Aunt/Niece/Nephew, Great-Grandparent/Grandchild 6 6
1st-3rd cousin 1 1
2nd-3rd cousin 5 4
2nd-4th cousin 127 132
3rd-5th cousin 1937 1900
4th to remote 6938 5676
Total 9014 7719

The closest relationships remained the same. One 2nd-3rd cousin moved to the 2nd-4th cousin range by losing 10 cM, 194 cM to 184 cM, but they were apparently on the threshold anyway. That match is actually my second cousin, so both ranges are accurate. It was also a transfer kit, so they did not test at FamilyTreeDNA. This revised match is probably the difference between actual reads and imputed reads in some regions, meaning the match is now more accurate.

275 matches had a predicted relationship change, but not uniformly in one direction, and no one moved more than one category in either direction. This all makes sense.

Match Differences

  Number
Matches found in both the apricot and purple spreadsheets 7,352
Unique (comparable) matches in both spreadsheets 7,174
Matches in original Family Finder apricot only 1,681
Matches in NGS purple only 400

A total of 7,352 matches appear in both spreadsheets, meaning the apricot and purple names matched exactly.

Unfortunately, some people had multiple tests, so I couldn’t always compare apples to apples because they appear three times or more on the combined spreadsheet, and I don’t know which of their kits are which.

If someone with the same exact name had more than one match for either or both tests, I did not compare them because their matching amounts were different, and I didn’t know which one(s) my old test matched, versus which one(s) my new test matched. Usually, one was an upload and one was a test at FamilyTreeDNA, but not always. I excluded those 178 match rows from the analysis.

Therefore, 7,174 matches could be directly compared.

There were 1,681 people who match ONLY on the old Family Finder test, and 400 that match only on the new NGS test. And yes, I downloaded the match files at the same time on the same day, so this comparison was controlled for any time difference.

cM Differences

  Number
Largest apricot match not in purple (NGS) list 26.3 cM
Largest purple (NGS) match not in apricot list 27.63 cM
Largest difference 69.86 cM NGS kit more
NGS detected greater over 10 cMs 19
NGS detected less over 10 cM 7
Total NGS greater 2,924
Total NGS less 3,040
No change 1,090

The largest value difference where a match appeared in the original apricot Family Finder test, and not in the purple NGS test, was 26.3 cMs.

The largest value difference where a match appeared in the NGS purple Family Finder test, and not in the apricot original Family Finder test was 27.63 cMs.

The largest difference between the two tests was 69.86 cMs larger detected by the NGS test. This match was a known second cousin whose matching cMs went from 373.06 to 442.92, but the longest block only increased a negligible amount from 87.47 to 87.69.

The next largest difference was with a 1C1R with a 41.56 cMs difference, also with the NGS-detected value being larger.

In all cases where the number of differing cMs was 16 or greater, the NGS had detected more.

There were very few tests that differed more than 10 cMs. In 19 cases, the NGS test detected a greater difference of 10 cMs or higher, meaning if the original test value was 100 cMs, in the NGS test, it was 110 cMs or greater.

In 7 cases the NGS test detected a smaller difference of 10 cMs or more, meaning that if the original test value was 100 cMs, in the NGS test, it was 90 cMs or smaller.

Out of the 7,174 tests being compared, 19 tests with greater than a 10 cM variation isn’t very many, around 0.26%.

In total, 1,090 matches had no change at all, while 2,924 NGS matches had more matching DNA detected, and 3,160 matches had less.

All but 287 of those differences were less than 5 cMs, and 6778 were less than 1 cM. In other words, literally not worth counting.

myOrigins Ethnicity

We all know to expect changes in our ethnicity from time to time at all vendors. The NGS test is exciting because it covers a much larger portion of our genome. As more people test, the reference library also becomes larger, which means that the ethnicity predictions can and will become more refined too

myOrigins Old Family Finder (apricot) NGS Family Finder (purple)
Central Europe 57% 52%
England, Wales, Scotland 28% 33%
Ireland 15% 14%
Magyar <1% <2%
AmerIndian Andes and Caribbean <1 (see below) N/A
AmerIndian North America <1% (chr 1 & 13) <1 (chr 1 & 2)
Anatolia, Armenia, Mesopotamia, North Africa <1 (chr 13) <1% (chr 10)

None of my major categories changed, but the amounts attributed to each category changed somewhat.

Trace regions, which are less than 1%, shifted some as well, as did their chromosome locations.

For me, this is particularly interesting, because I paint my ethnicity segments at DNAPainter in order to overlay my Native American segments over the matches with whom I’ve identified common ancestors.

Those segments, matches, and ancestors, taken together, help identify the source of the Native American segments.

My Native segment on chromosome one stayed essentially the same, but the Native segment on chromosome 13 is not present on the new NGS test. However, a new Native American segment is now shown on chromosome 2 in the same location that 23andMe also shows a Native American segment.

Chromosome one has already been proven to a Native American ancestor on my mother’s side, but I have hit a brick wall on the chromosome 13 segment. Now, I’ve painted the Native Segment on chromosome 2 and it aligns with the same ancestral line as my Native American segment on chromosome 1.

My Middle Eastern/North African segment still exists, but the location has changed. This segment was adjacent to my Native American segment on chromosome 13 before, on my father’s side, which suggested a history of enslavement. I thought I knew which ancestral line they both descend from, but now I need to review my matches and reconsider.

Unfortunately, my parents are both deceased and there’s no DNA available, so I cannot upgrade their tests or purchase new ones for them. No aunts or uncles are available either. In this case, cousin matches and their associated genealogy on those segments become critically important.

Native American and African American segments are often the best, and sometimes the only hints we have to find and identify those ancestors.

Preparing for Your NGS Results

To be very clear, you don’t necessarily need to compare or prepare, BUT, if you order an upgrade to an existing test, your old match list will be replaced with the new one. Your old match list will not be preserved unless you do it.

What may change?

  • Your ethnicity results will probably change somewhat
  • You will have matches you did not have before
  • Some existing matches, especially at low matching levels, will no longer be there
  • The amount of DNA you share with some people will change

Important: Any notes you have recorded on your matches and any matches that you have linked will be preserved and carried over to your new results when your new test is complete.

If you want to preserve your matches from your earlier test, or your myOrigins results, you’ll need to download your match list, and either download or take screenshots of your ethnicity information.

If you match the same person on the NGS test, this information is preserved for that match.

Where to Download

You must have 2FA (Two-Factor Authentication) enabled for all downloads.

The files you may want to download are found on your dashboard in two locations.

  • Family Finder Matches
  • Chromosome Painter (ethnicity)

Family Finder Matches Download

To download your list of matches with their complete information, click on Family Finder Matches on the dashboard, then on “Export CSV.”

This download provides all the fields mentioned above, whereas the Chromosome Browser segment download provides only your matching segment data, without the additional information.

Download MyOrigins Ethnicity Segment Data

To download your myOrigins ethnicity segments, click on Chromosome Painter on your dashboard, then on “Download Segments.” You can also view or copy those segments by viewing the Detailed Segments tab.

I paint these segments at DNAPainter so that I can correlate my ethnicity regions with my ancestors’ segments.

To assign segments accurately, it helps immensely to have at least one parent’s DNA results too, and preferably both.

You may also want to take a screenshot of your myOrigins map. Note the left-side scroll bar when you’re taking screenshots.

  • Link your individual matches to their place in your tree. This allows FamilyTreeDNA to use segments triangulated with linked matches to assign other matches to either the maternal or paternal side of your tree, or both.
  • Add your line to WikiTree. It’s easy. Begin with yourself and add ancestors until you connect with someone who is already in WikiTree. For me, it was the grandparent level.
  • Add your WikiTree link to your FamilyTreeDNA account under the gear in the upper right-hand corner, then Genealogy, then Family Tree. This gives your matches an easy way to identify common ancestors by using WikiTree’s Find Relationships feature, and provides two types of tree resources for you and your matches – MyHeritage and WikiTree.
  • Make sure your Earliest Known Ancestor information is correct and up-to-date with your most recent research, including a specific map location. You’ll find that under the gear too, then Genealogy, then Earliest Known Ancestors.
  • Add your surname list to your profile under the gear, Genealogy, Surnames tab.
  • Use the Matrix tool at FamilyTreeDNA to see how much DNA your shared matches share with each other.
  • Y-DNA – If you’re a male, test your Y-DNA, which is your father’s direct paternal line. The Big Y-700 test provides you with matches and the most detailed information possible.
  • mtDNA – Everyone can take a mitochondrial DNA test, which shows matches and provides information about your mother’s direct matrilineal line.
  • Use Advanced Matching, found under Additional Tests and Tools on your dashboard page, near the bottom, which allows you to select from multiple tests to see who matches you on both types of tests. For example, those who match you on both your full sequence mtDNA test and your Family Finder test.
  • Join projects relevant to your family surname, geography or broader interests. You’ll find Group Projects in the top banner of your dashboard page after signing in.
  • Utilize the Discover tools for both Y-DNA and mitochondrial DNA results.

Check your matches often to see who is new and what might have changed as people upgrade to the new NGS test and more people test.

What is a Quick-and-Dirty Tree, and When Might I Need One?

Posted on by
11

You may have heard genealogists talk about creating a quick-and-dirty tree.

What is that, exactly? When and why would you want one?

Good questions.

Matches and Trees

DNA matches don’t always have useful trees.

They might have:

  • No tree
  • A partial tree with only a few people in the closest generation or two
  • A tree with some lines built out, but others not so much

What’s a genealogist to do? After all, it’s your match’s tree, not your tree, and you have no way to expand their tree.

Except, you do.

It’s called a quick-and-dirty tree.

Quick-and-Dirty Trees

A quick-and-dirty tree is essentially a “throw-away” tree that you construct at Ancestry with the express purpose of obtaining hints, including potential parents, in order to quickly build your matches tree backwards in time until you (hopefully) reach a common ancestor.

And yes, of course trees, hints and suggestions of any kind can be wrong – but that doesn’t mean they’re always wrong, and you’re not adding anything from your quick-and-dirty tree to your tree – or even displaying it publicly.

You’re simply trying to find a common ancestor by using what your match has provided in their tree. Think of a quick-and-dirty tree as a scratch pad of sorts.

Let’s work through an example.

Initial Analysis

In this example, Ancestry has already told me that this match is most probably my half-second-cousin (half 2C) or second-cousin-once-removed (2C1R) based on the amount of DNA that we share, although the full relationship range includes several more options.

Ancestry also tells me that this match is on my maternal side. There’s no information provided about whether this match is on their maternal or paternal side, or even both.

A second-cousin (2C) relationship means that we share great-grandparents, and once removed means that one of us is one step further down the tree than the other person.

In other words, I’m 2C with my match’s parents, or my match is 2C with my mother. I wrote about this in the article, Concepts: What Does a Cousin “Once Removed” Mean?

I see that my match has a public linked tree with 7 people, which probably isn’t going to be terribly helpful.

Of course, the first thing to do is to review my match’s tree and see if I recognize either their surname or the names in their tree.

This tree only reaches back two generations, and our common ancestor, based on the relationships predicted by shared DNA, would be another generation, or two, further removed.

I don’t recognize any of these names, although I’ll review each person for a location to see if I can narrow the scope to the couple most likely to lead to our common ancestor.

On my mother’s side, one of her parents is from northern Indiana, and one is from southern Indiana, but not everyone enters locations in their trees, and they aren’t necessarily accurate.

The list of “all people” in my match’s tree, under “Find in tree”, at far right, provides additional information. Unfortunately, this tree shows Earl Townsend’s wife’s name as Mildred Ideal Thorstenson Townsend Smith here and in her profile, but the name order differs. To begin, I’ll enter Thorstenson Smith, not her married name of Townsend, in the quick-and-dirty tree I’m building. You can refine this shortly.

In this case, it looks like the Townsend line is most promising to find a common ancestor, given that Fulton County is in northern Indiana, but we’ll find out that this isn’t the case when we construct our quick-and-dirty tree.

Building the Quick-and-Dirty Tree

You need to build a new tree, NOT add to your “real” tree.

At Ancestry, go to Trees in the top banner, then click on “Create and Manage Trees.”

You’ll see the list of trees that you own. This is where all of the trees that you create live.

At the far bottom, you’ll see the prompt to create a new tree. Click there.

Next, you’ll see a blank tree.

For the home person, you can enter your match’s name, but be sure to list them as living so you’re not revealing private information.

After adding one parent, you’ll be prompted to save and name the tree. Both the tester, who is designated as male by the Ancestry icon, and his father are either both living, or private, so I’m simply entering the surname of Robinson based on the grandfather’s surname. That could be incorrect of course, but it’s all I have to go on – yet.

Ironically, their grandfather’s surname was spelled Robison, without the “n”, not Robinson, but I accidentally entered Robinson and still got where I needed to go.

Clearly, I’m not going to allow this tree to be viewed by others, aka public, so I’m not checking that box. If it’s checked by default, uncheck it.

I don’t make my quick-and-dirty trees public because they are entirely unproven and unverified. I’m literally quickly searching for hints with every intention of abandoning the tree when I’m finished. If you want to clean the tree up later, you have the option to change the tree’s privacy settings.

Information in Your Match’s Tree Might Be Wrong

Complete the tree to be the same as your match’s tree. After saving your tree, click on the individuals you’ve added to view their hints.

Let’s start with Earl Townsend who appears to be our best candidate based on location.

Earl Russell Townsend has 13 hints, including a marriage license that confirms his birth date and location and provides the names of his parents, plus his wife’s name as Mildred Thorstenson. Based on what we know already, this is probably the correct Earl Townsend.

Of course, the wife’s surname could be incorrect. It could be her first or second marriage, or she could have been a widow when they married, so this surname might not be her birth surname.

Look for additional records in Earl’s hints.

Russell’s death certificate confirms that information, as do the birth and death certificates of their children.

Accept those hints.

If you determine that the original information in your match’s tree is incorrect, you’ll want to correct it in your quick-and-dirty tree. Remember, this is a scratch pad – you can’t hurt this tree.

Let’s change Mildred’s name to reflect her birth surname.

I refined Earl’s wife’s name to Mildred Thorstenson, which then produced 12 hints for her, including her marriage and Social Security record, with her birth and death dates, and her parents’ names. Her name in my match’s tree of Mildred Ideal Thorstenson Townsend Smith had produced zero hints.

Additionally, census records showed Mildred with her parents.

These seem to align, so accept those hints.

Looking at the pedigree view of my quick-and-dirty tree, we now see that both Russell and Mildred’s parents identified in the records are suggested as their potential parents.

Review each suggestion. If they look accurate based on the records identified, accept those potential parents in order to view the next generation.

Based on these names and census information, I can eliminate the Thorstenson line. It’s Swedish, not German or Dutch, which comprise my mother’s northern Indiana lines, My mother has no known Swedish ancestors, and we have proven her Indiana lineage in this timeframe.

Accepting the hints for the parents of both Earl Townsend and Mildred Thorstenson, parent hints appear for John Townsend and Eva Martin.

Now we’re viewing the next group of hints, which would be the great-great-grandparent generation. If these are our common ancestor, that would mean that I’m third cousins with my match, which is beyond the predicted relationship range. Third cousins is not impossible, but it’s beyond the probable match level based on the amount of shared DNA. furthermore, I don’t recognize any surnames.

So, let’s move to the Robison (incorrectly spelled Robinson) line and step through the same process. We can always come back and work with more parental hints on the Townsend/Martin line if we need to.

Rolland Robison only has a death year in my match’s tree, and that combined with the misspelled surname meant he had no hints on Ancestry, so I clicked on “Search” in my quick-and-dirty tree.

I’m searching for a man by this name, with a wife whose first name is Chloe.

AHA!

There it is! Note that Ancestry found Rolland Robison, not Robinson, married to Chloe.

Chloe was a Ferverda. My mother’s father was John Ferverda, and the location is correct for this family.

I saved this record to Rolland Robinson and added Ferverda as Chloe’s surname in our quick-and-dirty tree. This provided Rolland with 12 hints.

Adding Ferverda as Chloe’s surname provides her with a dozen hints too, including potential parents, Hiram B. Ferverda and Evaline Louise Miller – my great-great-grandparents who are indeed the 2C generation.

These common ancestors fall within the expected amount of shared DNA for second cousins, so this aligns well.

My quick-and-dirty tree has revealed at least one pair of common ancestors. Could there be more common lineages? Yes. I would continue building out this quick-and-dirty tree for (at least) another couple of generations on the other lines just to be sure.

What Next?

That depends on what you want to accomplish and your genealogy goals.

I used a DNA match at Ancestry in this example, but your match might be at a different vendor. Regardless, you’ll still want to use Ancestry to build your quick-and-dirty tree based on how they present hints and potential ancestors.

Now that you know how your DNA match connects:

  • Minimally, make a note on the match that indicates the most recent common ancestor(s) identified. I include a link to the quick-and-dirty tree I’ve created.
  • You can add your match and their ancestral path to your common ancestor into your own tree at whichever vendor where the match occurs.
  • If you match at either FamilyTreeDNA or MyHeritage, both of whom provide segment information, I suggest painting your matching segments to DNAPainter.

Painting your segments identifies your matching segments as descending from those ancestors and makes it easier to identify the shared ancestral lineage of anyone else who shares that segment on the same side of your tree (maternal or paternal).

Word of caution here: You can potentially share multiple ancestral paths with any match, so different segments with one match can descend from different ancestors.

  • If your match is at FamilyTreeDNA, you’ll want to link your match to their place in your tree.

Using triangulation, FamilyTreeDNA utilizes linked matches to assign matches who share the same segments to the maternal or paternal side of your tree (or both) using triangulation.

  • You may be trying to break through a brick wall by identifying common ancestors BETWEEN your shared matches that aren’t in your own tree.

This approach is obviously easier the closer your brick wall is in time to the present. Great-grandparents, at the second-cousin level, and great-great-grandparents at the third-cousin level are much easier than 5th- or 6th-generation ancestors who lived before birth and death certificates and detailed census records existed.

Furthermore, the further back in time, the more likely that you may encounter:

  • Pedigree collapse, where the same ancestors appear more than once in your tree
  • Or you share multiple common ancestors with your matches

Of course, there’s always the possibility of endogamy too, where you descend from a historically heavily-intermarried population, such as Ashkenazi Jews or the Amish, for example, which means you may share segments passed down within the population from distant common ancestors you won’t be able to identify. While endogamy in your lineages may increase the amount of shared DNA, which in turn can skew relationship estimates, it won’t prevent you from using quick-and-dirty trees to locate common ancestors.

And finally, unexpected parentage or issues like record destruction may impede your progress, but you’ll never know if you don’t try, which brings us back to the purpose of quick-and-dirty trees.

Building a quick-and-dirty tree is the easiest way to grow your matches’ trees to reveal your common ancestors.

RootsTech 2026 – The Wind Beneath Our Wings

Posted on by
5

I started writing this article on Sunday evening, the day after RootsTech ended, and I’m basking in the afterglow. Also, my back and feet may never forgive me.

As a tongue-in-cheek comment, I think someone coined the word “exhausterwhelmulated” and defined it as being exhausted, overwhelmed, and overstimulated all at once. Yep, that’s me.

However, I need to add another couple of words to this – gratitude and joy.

Gratitude and Joy

I’m going to try to express this without sounding too sappy.

Do you recall the joy you used to feel when you spotted a relative you loved dearly but didn’t get to see often? Think of the unbridled joy as you piled out of your parents’ car and spotted your grandmother coming out of the door because she saw the car pull up. You ran as fast as your little legs could carry you directly into her arms, and got hugged so tightly it nearly squeezed the breath out of you.

I don’t know what the word for that would be, but it’s similar to how RootsTech feels.

Let me explain. Continue reading →

AutoKinship by Genetic Affairs Builds Family Trees from Your Matches at FamilyTreeDNA, and More

Posted on by
8

Genetic Affairs released a new AutoKinship tool designed for FamilyTreeDNA’s autosomal Family Finder matches, which also incorporates information from other sources. I must have fallen asleep at the wheel, because AutoKinship has been available for more than six months now.

I’ve been testing this tool with my matches, and it’s an immense help to those of us trying to untangle complicated family relationships using DNA evidence. I don’t know about you, but I have a long list of brick well where I could use help!

How to Use This Guide

This article is long and there are many steps involved – but it’s well worth it at the end.

My suggestion for using this article effectively is to read it through, at least once, to see what you’re going to be doing, and why.

Then, after you get things set up at Genetic Affairs, and any files you want to include, come back and use this article as a step-by-step guide to navigate these new tools.

Here’s the bottom line. The Genetic Affairs tools use matches, along with shared and bucketed matches at FamilyTreeDNA, plus their archived trees, in addition to external GEDCOM files and other information that you can provide in order to create customized, focused clusters and potential family trees for your clustered matches.

These tools combine DNA matching with internal and external trees for the composite best of both types of information.

So grab your favorite drink and let’s get started.

FamilyTreeDNA

AutoKinship works in conjunction with FamilyTreeDNA’s tools, such as Shared Matching, the Matrix tool, and Family Matching, also known as bucketing, which assigns parental sides to your matches using linked matches.

Linked matches are your matches whose relationship to you is known. If you haven’t already, link them to their profile card on your tree by clicking on “Link on Family Tree.” This allows FamilyTreeDNA, by using triangulation, to “bucket” your matches either maternally or paternally – meaning if they are related to you on your maternal side, paternal side, or both.

In my cousin Patricia’s case, the little pink icon by her profile picture shows that she has been bucketed maternally. That occurred when I linked my mother’s DNA to my tree because Patricia matches us both, plus other linked maternal cousins, on the same segments. For bucketing to occur, you don’t have to do anything except link known relatives to their proper place in your tree. FamilyTreeDNA does the rest by assigning your matches either maternally or paternally if they match on common segments.

Upload DNA Files to FamilyTreeDNA from Other Vendors

If you have not taken the Family Finder test at FamilyTreeDNA or uploaded your DNA file from 23andMe (Dec 2010 to present), Ancestry (May 2012 to present), or MyHeritage (March 2019 to May 7, 2025) to FamilyTreeDNA, you should do so now to take advantage of their tools, plus AutoKinship at Genetic Affairs.

What is AutoKinship and Why is it Different?

AutoKinship takes traditional clustering and kicks it up several notches. Instead of just showing you which matches cluster together, it actually attempts to build family trees based on the shared DNA amounts between your matches.

AutoKinship looks at how much DNA your matches share with you, and with each other, and uses that information to predict their relationships. Then AutoKinship builds potential family trees showing how everyone might connect. Additionally, you get to provide input in the process.

The timing couldn’t be better, especially since FamilyTreeDNA recently launched their updated Matrix tool, showing how your matches are related to each other. I wrote about that, here.

Two Steps

There are two primary steps in the AutoKinship process that build on each other. However, within these steps, there are many stepping-stones, so I’ve documented each one.

We’re going to use these tools, one at a time, in order.

I suggest that you join the Genetic Affairs User Group on Facebook for additional support and information.

Using AutoKinship with FamilyTreeDNA

The AutoKinship functionality for FamilyTreeDNA provides an automated approach using both AutoCluster and AutoKinship, together, then AutoLineage, where you can refine the information in a number of ways.

🔹 Step 1: Automated AutoKinship via Genetic Affairs

The first step involves running the AutoKinship tool directly from the Genetic Affairs members’ site. This process is fully automated:

  • It starts with the FamilyTreeDNA AutoCluster option, which groups DNA matches into shared clusters based on their connections to each other.
  • AutoKinship is then automatically launched on each cluster, adding the DNA tester and generating relationship hypotheses among the group.
  • Several family tree models are produced, showing how the matches and the tester could be connected based on shared DNA and cluster structure.

This step is ideal for getting quick insights into how groups of matches may relate.

🔹 Step 2: Refined Clustering & Relationship Analysis Using AutoLineage

After the automated run, downloadable files for AutoLineage are generated. These files allow you to re-import the match, shared matches, and tree data into the AutoLineage web application for further analysis.

This second step offers greater control and customization:

  • You can redo the clustering, optionally tweaking parameters to fine-tune how matches are grouped.
  • You can redo the common ancestor analysis, optionally tweaking parameters to fine-tune the discovery of MRCAs
  • The AutoKinship tool within AutoLineage becomes available again, this time with additional functionality:
    • Define known relationships between matches, such as parent-child or cousin relationships
    • Define generational information, for instance, if you know certain matches are not on the same generational level
    • Integrate MRCA (Most Recent Common Ancestor) data from reconstructed trees, e.g., from the Find Common Ancestors module.

This enhanced phase is especially useful for integrating genealogical trees for targeted clusters.

By combining both steps, automated clustering with AutoKinship, and manual refinement with known or tree-derived relationships using AutoLineage – you can leverage your FamilyTreeDNA data for in-depth relationship exploration.

Let’s Take AutoKinship for a Spin

As always, I’ll walk you through this process step by step, using my own DNA results as an example.

Getting Started

First things first – you’ll need to be a member of Genetic Affairs, so sign up for their free membership, here. Genetic Affairs’ customers purchase “credits” to spend on various features and reports, but you receive 200 free to start.

The automated AutoKinship analysis available on the Genetic Affairs website can be run using credits from the free tier – perfect for exploring the tool without any commitment. This allows users to generate relationship trees for FamilyTreeDNA clusters right away.

To access the more advanced features in the AutoLineage desktop application—including refined clustering, manual relationship input, and integration of MRCA data from reconstructed trees – you’ll need an active subscription.

To get started, sign in to the Genetic Affairs member site, here.

Let’s walk through the process step by step.

We’ll begin by registering a FamilyTreeDNA profile at Genetic Affairs. Click on “Register a new website” to get started.

FamilyTreeDNA account passwords are not stored at Genetic Affairs.

After clicking “Register profile,” you’ll see a message asking you to double-check the credentials for the kit you’re about to use. This is also a good time to log in to your FamilyTreeDNA account directly to make sure there are no pending actions — such as enabling two-factor authentication or accepting updated terms of service.

Once you click “I understand, continue,” you’ll see a list of all registered FamilyTreeDNA profiles at Genetic Affairs.

Locate the kit you want to analyze and click the blue “Start analysis” button.
This opens a guided wizard that walks you through each step of the setup.

First, select AutoKinship and click “Next.”

You’ll then be asked to define several thresholds:

  • Minimum and maximum shared cM
  • Minimum size of the largest segment
  • Minimum cluster size

A quick word of caution here: selecting a very low minimum cM value may actually reduce the number of usable matches. That’s because the system must download shared match data until it either reaches that threshold, or a preset timer expires, which can limit how much data is downloaded. When in doubt, start conservatively. You can always rerun the analysis later and change the parameters. Unfortunately, there’s no way to simoly “get everything” in one run which is, of course, what everyone would do.

Click “Next” to continue.

This section determines which matches will be included in the analysis.
For your first run, I recommend using the top matches within the selected range. This provides a strong foundation and usually produces the clearest results.

Later, once you’re more familiar with the output, you may want to experiment by analyzing only the shared matches of a specific person or group. For now, keep it simple and click “Next.”

Here, you’ll enter your FamilyTreeDNA password (twice) so the system can retrieve the required data.

If you use two-factor authentication, you can enter the 2FA code here, as well. To do that, log in to your FamilyTreeDNA account, retrieve the code from your email, and paste it into the wizard.

Then click “Next.”

You’ll now see a summary of all the settings you’ve chosen. Take a moment to review everything. When you’re ready, click “Perform analysis” in the bottom right corner.

At this point, the Genetic Affairs servers take over and begin processing your data.

The Results Arrive

When your report is ready, you’ll receive an email with a download link. You can also access it through the notification panel in the top right corner of the Genetic Affairs site.

Downloading the report will result in a zipped file. Save it in a location on your computer where you can find it.

Critical Step

This step is critical and will save you a great deal of frustration: If you’re using a PC, you MUST extract or unzip the files before you can properly use them. I can’t tell you how many people skip this step and then wonder why they’re receiving error messages. Ask me how I know!

This is your zipped file.

If you try to open the HTML file while it’s still zipped, it might appear to work at first, but when you click on any links within the file, you’ll receive an error.

If this happens to you, close everything, right-click on that yellow zipped folder, select “extract all,” and then try again.

Now you’re set up, so on to the fun part – viewing the results.

Exploring Your Results

Once you have everything properly extracted and open the HTML file, you’ll watch your AutoCluster literally fly into place on your screen. I love this part. It’s like watching my family fly into place. I wish the actual genealogy research was this easy.

The new Genetic Affairs reports include significantly more information than previous versions.

You can change what’s displayed using the dropdown menu.

By default, you’ll see the shared cM amounts between your matches, but you can change this to show paternal or maternal information if you’ve identified those lineages by linking your matches.

In my case, my maternal line has fewer matches because my mother’s ancestry includes both recent Dutch and German immigrants, so the majority of my high cM matches are US-centric on my father’s side. My father’s ancestors have been in this country since colonial times, and a lot of testers in the US are looking back to the old country for their origins.

Therefore, in my first several clusters, I see squares with the symbol P, indicating they are paternal matches – designated as such through linked family matches, aka bucketing.

You can see the faint Ps inside the orange cells.

Here’s a close-up so you can see the “P” for paternal. If you haven’t linked your matches, you won’t have bucketed matches. Your Genetic Affairs results don’t require bucketing – it’s just a really beneficial feature.

You can change your AutoCluster settings in several ways. I tend to start with the defaults and then modify from there.

Genetic Affairs functions based on the amount of server time a particular tool takes, so it’s not possible to just “run everything,” or trust me, I would.

The Common Ancestor Magic

In your report, scroll down several sections, and you’ll find Common Ancestors – my favorite feature.

This section shows you the common ancestors that have been identified between your matches’ trees.

Looking at the Common Ancestors cluster report, you can click on three things for each cluster:

  • FamilyTreeDNA Trees of Cluster #
  • Common Ancestors of Cluster #
  • Common Locations of Cluster #

Let’s examine the reconstructed trees based on the common ancestor analysis. The first cluster shows some of my close DNA matches that are descendants of my Vannoy line.

You can see that there are six testers, in addition to me, who descend from Joel Vannoy.

Next, scroll down to the AutoKinship section of your report.

The AutoKinship Analysis

The real treasure lies in the AutoKinship analysis, which is presented in a small table on the main HTML page. When you click on the AutoKinship results for any cluster, you’ll see reconstructed trees based on the shared DNA amounts between matches, meaning between you and each of them, and between each other.

You can see that I have 10 reports available based on the cluster numbers indicated.

I clicked on Cluster 1, which shows some of my close DNA matches who are Vannoy line descendants. This includes testers both with and without trees.

Since the AutoKinship algorithm doesn’t have access to age information, it sometimes struggles with generational differences – but the relationship predictions are still remarkably useful.

Alternative trees are also provided, giving you multiple hypotheses to investigate.

Some matches may not be integrated because of incompatible relationships.

The Next Step with AutoLineage – Adding Genealogical Trees to the Mix

We’ve seen AutoTree and AutoKinship. The new upgraded AutoLineage adds genealogical tree information to genetic information by allowing the user to:

  • Import other trees
  • Integrate most recent common ancestors (MRCAs) in AutoKinship trees
  • Set known relationships
  • Provide generational information.

AutoLineage, Genetic Affairs’ online clustering and tree-building tool, has been around for several years but was recently upgraded to create trees based on shared DNA and incorporate genealogical evidence.

This is where the proverbial rubber meets the road.

Setting Up AutoLineage

Return to the home page at Genetic Affairs and select AutoLineage.

If you’re new to this tool, you’ll see a simplified workflow on the start page that walks you through the process.

First, create a profile representing the DNA test taker – in my case, that’s me.

After creating the profile, you’ll be redirected to the landing page of the profile. From there, you can register DNA tests linked to the profile. From the home page, you can see the different profiles.

You’ll register a new FamilyTreeDNA test specifically for each user whose kit you manage and who took a test.

FamilyTreeDNA is the only DNA testing company for which Genetic Affairs runs automated analyses on their site.

Additionally, you can:

Importing the Data

After registering a FamilyTreeDNA test, you are redirected to the overview of this DNA page, where matches are imported.

Click on “Import matches” and select the CSV file from Genetic Affairs. Here’s where that AutoKinship report we generated earlier comes in handy. The unzipped report contains match and shared match information that we can import directly into AutoLineage.

Navigate to the gephi folder in your report and select the nodes.csv file to import your matches.

After importing the matches, a short dialog shows how many matches were imported.

After closing the dialog box, the DNA matches pane is opened.

You’ll see your DNA matches that were downloaded.

Next, import the shared match information from the edges.csv file in the same gephi folder.

Once both data sets are imported, you’ll see that the ICW (In Common With) column has populated, showing how many shared matches are available for each DNA match.

Clustering in AutoLineage

Now, with the shared match data loaded, you can perform your own clustering analysis.

The wizard allows you to set parameters for which matches to include based on:

  • The amount of shared cMs
  • Weighted or unweighted clustering
  • How much DNA is shared between shared matches

You can also define the cluster characteristics, from sparse to very dense clusters.

Last, you can select the coloring scheme. After setting the parameters, click on “Start Clustering,” at bottom right.

After clustering is finished, the clustering chart is displayed. It looks fairly similar to the ones obtained automatically from Genetic Affairs, but with some differences.

The first thing I noticed is that the large orange cluster 1 in the automated clustering is now mostly represented by the purple cluster 4.

Let’s zoom in on this cluster. By looking more closely at the numbers contained in each cluster, you can already make an estimated guess about the richness in relationship information for cluster members. This cluster has lots of close relationships. Clusters whose matches only share a small amount of DNA with each other are not the best candidates for an AutoKinship analysis because they most likely share a distant common ancestor. Unless, of course, it’s a distant ancestor you’re searching for. (Hello brick wall.)

Adding and Importing Tree Information

Now that we have the new clusters, we could continue to directly run the tree reconstruction on these clusters using the shared DNA information, but let’s wait  since we want to include the tree information as well to guide this process.

To use common ancestors, we need to import the available trees that are linked to the DNA matches. Luckily, just like (shared) match information, the tree information is provided with the automated analysis as well. Let’s import the data.

First, navigate to the tree management page. As you can see, no trees have been created or imported. Let’s start the wizard by clicking on the “Import Trees” button.

An “Import tree” wizard pops up, providing different ways to import tree information. It’s also possible to import GEDCOM files or tree data from other resources, but for now, I’m only using the archived trees at FamilyTreeDNA.

Click on the last option and select the files.

Navigate to the matches folder and select the HTML files contained in the folder.

Each file represents a DNA match report, some of which have a tree associated with them.

After importing the trees, they are automatically associated with the concerned DNA matches (using the unique identifier present in each file name). The tree overview page shows which tree is linked to a profile or DNA test, and the amount of DNA shared with the linked DNA match.

If you have created trees for your matches based on your own research (like quick and dirty trees), now is the time to import these using the “Import Tree” wizard again. This is a wonderful feature, because it means you’re not entirely dependant on your match having uploaded a tree themselves.

If you don’t import trees from GEDCOMs, you don’t need the linking wizard.

Click on the “Import Tree” wizard and select the GEDCOM option.

Now that we have imported additional trees, we need to associate them with DNA matches.

You can use a wizard to link the unlinked trees to the DNA matches, or link them from each DNA match. The wizard will try to guestimate, based on the content of the tree file name, which DNA match could be associated with the tree. Change the search criteria if it does not provide the correct results.

TIP: Save the GEDCOM files with the name of the linked DNA match as well the shared cM, which speeds up the importing process

Don’t forget to import your own tree. I imported my GEDCOM file from my computer genealogy software and associated it with my profile so it’s included in the common ancestor identification. You can easily upload your GEDCOM from your computer software, or download your tree from either Ancestry or MyHeritage to upload here.

Visit the profile, and select the tree pane. The tree pane only shows a single individual and allows you to add ancestors to it manually. To associate that individual with an existing tree, click on “Link to Existing Tree”.

A wizard will be displayed, which shows all available trees on the left side. Sort by clicking on the “Created” column to display the most recent trees.

Next, you need to select the root person.

I selected my tree.

Next, the right side of the wizard fills with the people in the selected tree. Select the root person, which is me, and click on “Save” in the lower right corner.

Finding Common Ancestors

Now that we have associated a tree with the profile and imported trees for the FamilyTreeDNA matches, it’s time to locate some common ancestors. Fingers crossed!

Go back to the profile and select the profile overview. Scroll down to the “Find common ancestors” section and click on the “Find common ancestors” button.

The “common ancestors” wizard shows trees that are associated with this profile in the table on the left and provides information about the different steps on the right. You can change the settings to make the search more restrictive or more relaxed.

After running the common ancestor identification, a dialog shows the number of trees and tree persons that were used, and the number of common ancestors that were identified.

After the analysis runs, you’ll be able to view all reconstructed trees or filter them based on common ancestors, trees, or linked DNA matches.

Common ancestors, not surprisingly, often align closely with what the automated analysis discovered.

All six testers are now shown descending from our common ancestor, in the approximate location where they will fit in our common tree.

But we aren’t quite finished yet.

The Final AutoKinship Analysis

Finally, we’ve arrived. The earlier steps were necessary to pave the way.

We have the common ancestors and clusters, and it’s time to go back to the clusters to begin the reconstruction of trees using trees combined with DNA.

Click on the profile and go to the clustering results pane. Select the 1x view, which will show the clustering chart.

Now select the matches pane that shows the different matches that are contained in each cluster. Scroll down until you reach your cluster of interest, which is four for me.

After clicking on any cluster, you’ll be redirected to a cluster view with only the information for that particular cluster.

Let’s view purple cluster 4, which looks fairly dense, with only a couple of empty cells, indicating that these shared matches with white cells did not share (enough) DNA with each other to be included in the cluster. Now select the matches pane in the dashboard at the top of this cluster, which displays the matches linked to this specific cluster. As you can see, a button is now available that allows us to run the AutoKinship analysis. Click on the button.

Single cluster matches are displayed.

Now back to the wizard.

The wizard provides several important parameters:

  • Maximum number of generations between DNA matches
  • Number of trees to analyze in each iteration
  • Final number of trees to keep
  • Whether to include known relationships and/or MRCA (Most Recent Common Ancestor) relationships

In this example, MRCA relationships were found because we performed the common ancestor identification that resulted in common ancestors between the matches of this cluster.

If you know specific relationships between matches, you can set those manually. Sometimes you might not know the exact relationship, but if you can estimate that a match is one or more generations older or younger than yourself, you can set that too.

In addition to setting the relationship between the test taker (indicated in green in the table) and the DNA matches, it’s also possible to set the relationship between shared matches, if known.

The Hybrid Results

After the analysis has finished, an overview of the identified trees is presented.

The final result is a blended tree where DNA evidence fills in the blanks for matches who haven’t uploaded trees, or you haven’t provided a tree, and known genealogy supports the structure where it exists. This hybrid approach gives us the best of both worlds – the precision of documented genealogy combined with the discovery power of DNA analysis.

I particularly like this approach, because when I identify how a DNA match is related to me from any vendor, I enter their lineage in my desktop genealogy software. Therefore, using that GEDCOM file is the most complete source of my identified relatives.

Testers 1-6 were shown using the regular AutoTree, without the integrated tree, but an additional 11 matches were placed for consideration using all available tools.

I was using this as an experiment because I know how most people in this cluster are related, and those are all placed accurately. There is one person, located on the branch between 1 and 5, who I had no idea how they fit into this puzzle. Now, at least I know where to look.

I can’t imagine trying to do all of this manually.

Why This Matters

For those of us dealing with unknown parent or grandparent situations, poorly documented lines, non-existent trees, or just plain stubborn brick walls, this combination of tools is nothing short of amazing. You can now explore relationship hypotheses even when traditional documentation is scarce.

The reconstructed trees show how common ancestor information provides the template, while the AutoLineage tool fills gaps using shared DNA information. The updated AutoLineage is the genealogical assistant that never gets tired and can deal with relationship possibilities much more effectively than traditional hand-based methods.

In Summary

If you haven’t explored Genetic Affairs recently, give it a look. The integration between AutoKinship and AutoLineage represents a significant step forward in DNA analysis.

While AutoKinship offers valuable insights on its own, its full potential is truly unlocked when you export the data into AutoLineage. The combination creates a comprehensive analysis that was previously impossible.

For researchers dealing with complex family relationships or challenging genealogical puzzles, this hybrid approach that combines matches at FamilyTreeDNA with DNA evidence and genealogical trees could be the key to breaking through stubborn brick walls that nothing else has budged.

Last but not least, I suggest reading Dr. Patricia Coleman’s blog articles about these tools and her methodologies here and here. Patricia works extensively with these tools, and I often recommend her for private autosomal research consultations. Patricia’s 2026 RootsTech Session, DNA Case Study: Finding an 1877 Birth Father with Genetic Affairs, BanyanDNA, and No Birth Record, details her work solving a long-standing problem for my cousin in the Speaks family.

2025 Genetic Genealogy Retrospective: Wow – What a Year!

Posted on by
5

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

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

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

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

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

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

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

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

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

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

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

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

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

Click here to order the new test.

#3 – 23andMe Experiences Problems

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

Best Genealogy Tool

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

A Cautionary Word About AI – Artificial Intelligence

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

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

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

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

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

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

Tried and True Genetic Genealogy Staples – DNAPrint and Genetic Affairs

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

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

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

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

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

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

Major Vendor Releases

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

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

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

Additionally, MyHeritage released a new ethnicity version.

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

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

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

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

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

Conferences

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

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

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

Concepts, Techniques and Plain Old Genealogy

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

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

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

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

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

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

Memorial Articles

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

Be the Storyteller

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

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

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

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

Find a way to share about your ancestors!

Concepts: What is a Half-Relationship, Like Half First Cousins, Anyway?

Posted on by
4

Pretty much everyone knows what a half sibling is – someone who shares one, but not both parents with each other.

If you and your sibling share the same mother, but not the same father (or vice versa), you’re half-siblings. Only one parent is shared between half-siblings.

If you share both parents, you’re full siblings.

Step-Siblings

Step-siblings are often confused and used interchangably with half-siblings, but they aren’t at all the same. And yes, it matters.

If your parent married someone who already had a child, but both you and that child were born to prior (or future) marriages/relationships of your respective parent – you’re step siblings.

In other words, your parents are married to each other, and you may live in the same household, but you don’t share a genetic link with a step-sibling because you don’t share any parent in common.

By way of example, my mom married a man who had a son from a prior marriage, and his son is my stepbrother. The man my mother married is my stepfather.

My mother is my stepbrother’s stepmother.

The real message here, other than clarifying confusing relationship terms that are often used incorrectly, is that:

  • There is a biological relationship between full-siblings and half-siblings
  • There is no biological relationship between step-siblings, unless one exists due to ancestors someplace in the past

I wrote about how much of your ancestors’ DNA you can expect to inherit in the article, Ancestral DNA Percentages – How Much of Them is in You?.

Genetically, Half Versus Full Matters

The amount of autosomal DNA that is expected to be shared between full-siblings and half-siblings differs. Throughout this section, I’m using words like “expected” and “about” because in reality, after parents, “exactly” half of the ancestral DNA in a specific generation does not get passed to the next generation. Random recombination is a factor and therefore, the expected inherited percentages are approximate.

Full siblings share both parents, while half-siblings share only one parent, so full siblings share about 50% of their DNA, while half-siblings share about 25% of their DNA – and only from one parent.

Therefore, every descendant relationship from full or half relationships varies by 50% between the two types of relatoinships.

Half-siblings can be expected to share, on average, half as much autosomal DNA as full siblings – because they only share one parent – not two.

For example, first cousins (1C) share about 12.5% of their DNA, but half first cousins (half 1C) share about 6.25% of their DNA.

In other words, the “half” designation literally means that those two people share half a relationship – one parent (or grandparent, etc.), not both, in the founding generation, and their descendants continue to share half as much DNA as a full relationship in the same generation.

Subsequent Generations

Extending those relationships down the tree generation by generation, we see that in each subsequent generation, the descendants can be expected, on average, to share one-fourth as much DNA with each other as the preceding generation. That’s because two transmission events have taken place, one in Child 1’s line, and one in Child 2’s line.

The same as in full sibling lineages, each subsequent half-sibling descendant generation can also be expected to share one quarter as much autosomal DNA as the preceding one.

“Removed” Relationships

If you encounter a situation where one side of the descendant tree is “longer” than the other by a generation or more, then you’re dealing with a phenomenon known as “removed,” such as first-cousin-once-removed (1C1R), or, in the example above, a third cousin (3C) once removed (1R).

The same concepts still apply. A half 3C1R would share half as much DNA as a 3C1R.

I wrote all about “removed” relationships and their genetic genealogy effects in the article Concepts: What Does a Cousin “Once Removed” Mean.

Summary

In this final chart, I’ve combined the full-sibling and half-sibling charts into one so that you can compare them easily. I’ve also removed the “other” parent that the half-siblings don’t share to conserve space.

I wrote about how much DNA each type of relationship can be expectd to share, both centiMorgans (cMs) and percentages, including relationships not detailed here, such as half-uncles and half-aunts, in the article Shared cM Project 2020 Analysis, Comparison & Handy Reference Charts.

Concepts: What Does a Cousin “Once Removed” Mean?

Posted on by
7

What is a first-cousin-once-removed (1C1R) or a second-cousin-once-removed (2C1R)? In these abbreviations, “R” means “removed.”

Once you understand what “removed” means, it’s really simple, but until then, it’s confusing.

Let’s start with first cousins.

First cousins share common grandparents. Jane and Mark are first cousins. Their parents are siblings.

“Once removed” means one generation offset, or the child of someone in that cousin generation.

Let’s say you’re Jane.

Your child, Jim, is the first cousin once removed to your first cousin, Mark. Said the other way, Mark is a 1C1R to Jim.

Jim and Mark are first cousins once removed.

Flipped around, so that we are comparing Mark’s child instead of Jane’s – Mark’s child, Maurice is a 1C1R to Jane.

Julie and Maurice are both the children of people who are first cousins to each other. They share Steve and Shirley as great-grandparents, so they are second cousins to each other.

Now let’s say that Julie has a son, James.

James and Maurice are second cousins once removed, because they are a generation offset from one another. James is the child of someone who is second cousins with someone else. In this case, James is the son of Julie who is a second cousin (2C) to Maurice.

Now, James has a child, Jill.

Jill and Maurice are second cousins twice removed, because they are another generation offset, or on down their branch of the tree..

Calculating “Removed”

Taking this one step further, Jill is a first-cousin-three-times-removed (1C3R) to Mark.

Cousin relationships are easy to calculate.

Look at the two people you wish to compare. In this case, Jill and Mark.

Find their common generation level. Looking back up Jill’s tree, we find Jane at the same generational level as Mark. Jane and Mark are first cousins (1C). That’s the base relationship before calculating the number of generations your target people, Jill and Mark, are “removed” from each other.

Beginning with the generation below Mark, count how many generations below first cousins Jill is “removed” from Mark.

In this case, in the column at right, you can see that the Julie/Maurice generation is “1”, followed by the James generation at “2” and Jill is generation “3.” Hence, Jill and Mark are 1C3R to each other.

Don’t confused a first-cousin-once-removed (1C3R) with third cousins (3C).

Third cousins would be James and Matthew. Fourth cousins would be Jill and Madison.

It’s easy to calulate the relationship of any two people in your tree.

I wrote about my “chicken scratch” method of calculating relationships in the article, Quick Tip: Calculating Cousin Relationships Easily.

DNA

As you might expect, the amount of expected shared DNA between two people who are second cousins (2C) and second-cousins-once-removed (2C1R) is different, because the DNA has been divided once more in James than it has been in Maurice.

In first-cousins-three-times-removed, the DNA has been divided once again in Jill.

I wrote about DNA and relationship predictions, including half relationships and “removed” relationships in the article, Concepts – Relationship Predications.

You can view expected amounts and ranges of shared DNA for various relationships using DNA Painter’s Shared cM Project tool, here.
