More Losses at 23andMe – Including No Ethnicity Update for V2, V3 or V4 Chip Customers

Did you test with 23andMe prior to August 2017? If you were among the millions of customers who tested in the decade between 2007 and 2017, you tested on the V1-V4 chip.

Unfortunately, 23andMe has made the decision to no longer provide ethnicity updates for customers who have NOT tested on the current V5 chip.

Moving to the V5 chip is not an upgrade – it’s a completely new test that customers must purchase and spit-to-submit again. This means that if your family member that you purchased a test for died, you’re just out of luck. Too bad – so sad.

Last week, 23andMe published this article detailing their new ethnicity improvements. Everyone was excited, but then the article ended with this spoiler at the very bottom.

I still can’t believe my eyes.

What – No Ethnicity Updates?????

In this industry, no company that I can recall has EVER failed to update ethnicity for earlier chips. Especially given that ethnicity is the hook that companies have used to entice many, many customers to test.

When FamilyTreeDNA changed from the Affymetrix chip to the Illumina chip in 2011, they retested every single customer FOR FREE.

FamilyTreeDNA, MyHeritage, and Ancestry have continued to update results for all customers on any chip level. Those companies would be publicly skewered alive if they did anything else.

As far as I’m concerned, this is a betrayal of the trust of 23andMe customers.

We know now that companies can easily utilize imputation for equalizing different chips for genealogy purposes. All three other major companies do exactly that with their own tests and in the case of MyHeritage and FamilyTreeDNA, with transfers from the other three major companies, including 23andMe’s current and older chip levels. Of course, imputation “fills in blanks” with “realistic values,” which is not appropriate for medical testing – and the underlying goal of 23andMe is medical research, not genealogy

Therefore, genealogy customers are being penalized in an effort to force them to the V5 chip if they want to view their new ethnicity updates or have more than 1500 matches, and then, only with a subscription.

This “sales strategy” is simply not acceptable.

Matches Restricted

This no-ethnicity-update revelation comes on the heels of 23andMe reducing the match threshold to 1500 FOR ALL CUSTOMERS unless customers have tested on the V5 chip AND subscribe, both.

I wrote about that change, here.

That’s Not All – No Search by Common Surname or Ancestral Location

The genealogy community continues to discover more losses. Hat tip to my blog subscriber who noticed that customers can no longer search by common surname or ancestral location.

23andMe confirmed that change in an email saying:

  • You can search for profile names and current locations in the DNA Relatives search section.

Wow, I don’t want my matches knowing where I currently live. is that really what’s happening? Surely not.

But sure enough, here’s one of my matches, minus their name of course.

This gives me cold chills. This information should never, ever, be available unless the tester gives it directly to another specific person.

Why would 23andMe ever implement a feature like this that causes potential physical security risks to their customers? I’d wager most people have no idea that this information is displayed to all of their matches. Fortunately, it’s only displayed if you specifically enter the information.

To check your location status, remove or update this information, click on the down arrow beside your name in the upper right-hand corner of your 23andMe page, then on “Settings”.

Scroll down and click on “Edit Enhanced Profile.”

Make any changes.

This is also the section where you enter other information that will help you connect with matches in a meaningful way. Be sure to share a link to a family tree someplace. While 23andMe is discontinuing some of the features that are important for genealogists, that makes it even more important to utilize the remaining features.

23andMe also confirmed that:

  • You can no longer search for family surnames, other locations, or any other user entered information.

This change is infinitely sad, because surnames, especially unusual ones are critically important to genealogists, and in combination with locations.

You can filter by ancestor birthplaces, but that only means through the grandparent level.

Not terribly useful for genealogists, and the US is a very big place. Knowing someone’s grandparents were born in the US is not helpful. However, if I have an ancestor from a location like Germany, this might be more useful.

You can also filter by SOME of your family surnames, but not all of them. Apparently, only your top 20 in terms of how many people share that surname. Just take a guess which one is highest on my list. Probably yours too.

My own surname and that of all 4 of my grandparents is missing from this list. I don’t find an ancestral surname until one of my great-grandparents’ surnames, Miller, appears. This list is really only a list of the most common surnames in the US that I happen to have in my genealogy.

No Haplogroup Search

Another feature that has disappeared is the ability to search your DNA Relatives by haplogroup. Granted, they were only partial haplogroups, but they could rule out a lineage connection to your direct matrilineal line or, if a male, your patrilineal line. If you knew your grandparents or other haplogroup lineages, you could do the same for them.

But not anymore

Where Are the Genealogists?

How has 23andMe moved so far away from the genealogy community? This feels like death by 1000 tiny cuts. Whittling away our features along with our trust.

At one time, 23andMe had a genealogy ambassadors program where experienced genealogical ambassadors represented the genealogy community and provided input. Unfortunately, 23andMe dissolved the program a year or so ago, but then again, they didn’t seem to listen much to their ambassadors anyway.

Health AND Ancestry

23andMe is increasingly pushing the health AND ancestry test on the V5 chip. I’d wager their medical and research partners want specific data on this chip that’s not available on previous versions.

When clicking on my V4 account, the upgrade available is only for both health and ancestry. There is no “ancestry only” test available like there used to be.

The $99 price for the V5 upgrade is the same for my V3 kit. Yes, I tested twice (three times actually on V2, V3, and V4) to understand the matching differences between the V3 and the V4 chip.

Truthfully, given the way 23andMe is treating their current clients, I have absolutely no desire to gift them with my health information to turn into revenue.

Consent or WithDraw Consent to Share Genetic Information

While 23andMe can utilize research information from surveys in some ways without your explicit consent, assuming you answer their surveys, which I do not, they currently don’t share your genetic data unless you opt-in to consent.

I’m not comfortable with not knowing who is using my DNA information and for what research purpose – but your comfort level may vary. 23andMe’s “designer baby” patent in 2013 ended my participation in research.

If you click on “Research,” then “Surveys and Studies,” 23andMe will remind you if you haven’t opted in for research.

You can check your current consent status by scrolling to the bottom of this page after you sign in.

click to enlarge

You will see your current consent status, and you have the ability to update your status with a different choice. Please read every document provided before consenting.

You can also access your Research Consent and other account settings by clicking on the down arrow by your name, at the far right top, and then on “Settings.”

Research Consent is very near the bottom, under Preferences.

May the Fleas of 1000 Camels Infest Your Armpits

May fleas infest your armpits, 23andMe, for removing the services and features that genealogists purchased and expect to continue to receive. Worse yet, you’ve damaged our collective credibility, because we’ve been recommending 23andMe to our family members and friends for years now, and purchasing kits for them, all in good faith. Now, we get the opportunity to apologize to our family members for your behavior. We trusted you, and we shouldn’t have.

In the past, 23andMe has always updated ethnicity for everyone. New medical and health reports weren’t always added, ostensibly because the necessary genetic locations weren’t on older chips, but genealogy features and updates were never held hostage before – nor was existing functionality removed except for trees.

In retrospect, the removal of trees was probably the first sign that 23andMe was seriously moving away from genealogists and was only paying lip-service in order to obtain our DNA for the very lucrative medical research business.

I haven’t always agreed with the decisions made by 23andMe in the past, but this time, I feel that 23andMe is intentionally acting disingenuously – blatantly arm-twisting their long-time genealogy customers by withholding updates we have every right to expect. Odd way to treat the community that stood by 23andMe and kept buying tests while the FDA had their health and medical reports shut down for two years, from 2013 to 2015 when they finally reached an agreement and began selling their health product again.

As a customer, your only recourse, other than complaining, which I encourage you to do (customercare@23andMe.com), is to opt-out of research consent. 23andMe may not hear our voices or care about our ethnicity or matches, but I bet they will notice the revocation of consent. Our DNA is a cash-cow for 23andMe as a DNA-broker.

Your other alternative to receive your updated ethnicity results, of course, is to purchase an upgrade and pay to test, again. Just like the only way to get more than 1500 matches is to upgrade plus pay a subscription fee – and then you’re still limited to 5000 matches. Upgrade or not, you won’t receive the other features they’ve removed.

Truthfully, there’s no way in bloody h*ll that a company is going to get me to spend MORE money by abusing my trust and attempting to strong-arm me in this fashion. Nada. That’s simply not going to happen.

I’d wager that treating genealogists in this manner is a very short-sighted strategy. We talk within this community and make recommendations to each other. 23andMe is generating a great deal of bad-will right now.

I left wondering what else existing customers will lose, and when the V5 customers will be arm-twisted to purchase a new test, yet again.

23andMe Changes – Download Matches Now or Lose Many

Recently, 23andMe implemented a new subscription model. In their new model, which requires retesting (with a new sample) on the V5 chip, you can pay a yearly subscription fee of $29 to receive up to 4500 matches.

The subscription service is by invitation, which you can see at this link, excerpt below:

click to enlarge

Current Customers Losing Matches and Losing Out

Unfortunately, without notice to customers, 23andMe is reducing (or has already reduced) the match cap for current, existing, customers from 2000 matches to 1500.

In the past, the 2000 cap was minus the number of matches that had not opted-in to sharing. The new 1500 cap is the top 1500 that HAVE opted-in to sharing.

In my case, I went from over 1700 matches to 1500.

In the past, you could actually retain more than 2000 matches if you had issued a sharing invitation or corresponded with your match. Now, all of that work is gone. One of my friends had more than 4700 matches through years of work and now has 1500.

This purge may not have happened to you yet, as they seem to be rolling through the database in stages. Check your matches and if you have more than 1500, work with them immediately.

More Features are Gone

Furthermore, other features have been removed, such as the ability to sort by haplogroup and notes and possibly more. I haven’t tested everything. What’s clear is that current customers are losing matches, features, and are being “downgraded.”

That’s very unfortunate, as this appears to be arm-twisting in order to encourage people to upgrade to the V5 chip and subscription service to retain existing matches.

Many people can’t upgrade because they have died. For example, if you manage a parent’s kit who is deceased, this purge will hurt you immensely because even if you do upgrade, you’ll not be able to phase your matches against their kit.

Preserving Matches

Unless you upgrade and subscribe, you can’t do anything to preserve your actual matches above 1500, but what you can do is to download your matches in spreadsheet format which, for now, still contains your previous matches.

This opportunity won’t last long, as 23andMe support has replied to an inquiry that they will soon be adjusting the download list to match your new 1500 match list.

We don’t know when this will happen, as 23andMe has communicated absolutely nothing about these changes to customers, so download now.

Downloading Your “Aggregate Data”

click to enlarge

On your DNA Relatives page, scroll to the very bottom.

Click on “Download aggregate data.”

A file will be downloaded to your system which will include a significant amount of information from your matches’ profiles. Of course, important information such as matches-in-common won’t be there, but at least something will be.

Download now before it’s too late.

Opinion

23andMe has always been focused on health, with genealogists being a means to an end. That’s why our matches have been limited and functions such as trees, similar to features at the other three major vendors, have never been implemented. This isn’t news.

23andMe has disregarded questions about where my DNA is being stored, which studies it was included in, and for what purposes before they implemented the opt-in system for medical research, as opposed to the opt-out system.

I opted out of research years ago, because I’m not comfortable not knowing how my DNA is being utilized, and by whom. Furthermore, I have an issue with the amount of money 23andMe is being paid for the DNA information I paid to test. 23andMe states that they have received $791 million in venture capital and lists their investors, here. With 12 million customers, that’s about $66 per customer or $99 for opted-in customer.

That being said, I have previously upgraded from V2 to V3 to V4, paying to retest each time, in part, so that I could write about my experiences for my blog followers.

This time, I’m not upgrading and I’m done. They’ve gone too far by reducing the match cap by 25% of the matches we were previously allowed, an artificial barrier not imposed by any other vendor. And that’s assuming you had done nothing to prevent matches from rolling off your list previously. Not only that, but this purge has been done without notice of any type.

I won’t be removing my DNA, because it’s already there (and I’ve paid for it 3 times), but I won’t be answering any questions for the 23andMe surveys which they aggregate for the data, I won’t be spending any money to upgrade, and I certainly won’t be recommending 23andMe except for adoptees and people seeking unknown close family who haven’t found their answers elsewhere.

As Kenny Rogers said; “Know when to hold ‘em, know when to fold ‘em, know when to walk away…”

Quick Tip – Trees, Death Dates and Unintentionally “Private” Ancestors

I manage trees for a number of DNA tests for my relatives at various vendors. DNA and trees work hand-in-hand to identify common ancestors, providing hints to direct you along that path.

If you don’t have a tree at the sites that support trees, meaning FamilyTreeDNA, Ancestry and MyHeritage, please either create one or upload a GEDCOM file from your genealogy software. Many of the features provided by those vendors depend on both your DNA results and the tree you’re linked to. While 23andMe does not support trees, you can include a link to a tree in another site under “settings,” then “enhanced profile” – so do that.

In many cases, especially for Y and mitochondrial DNA at Family Tree DNA, I only enter the relevant line for the tests taken. That way, anyone who matches my cousin can check their tree and easily view the relevant line for the test.

Often, especially if the person tested at my request, I’m the one who has done the genealogy and I don’t research the wives or collateral lines that are not relevant to the test that was taken. I don’t want to do a lot of maintenance work to export only a small branch from my desktop software, so I create each tree by hand from scratch.

Of course, if they have taken a Family Finder test, I upload a more robust tree for them that includes as much of their various lines as I know.

Uploading or creating trees helps us and other genealogists break through their brick walls too.

Ned Matched John – But Encountered a “Privacy” Roadblock

Recently, another Estes tester, we’ll call him Ned, matched the Y DNA of my cousin, John, and emailed me, saying that John’s entire tree was private. I told him that I had not made John’s tree private, so Ned sent me a screenshot.

click to enlarge

There’s no dispute – while the tree itself isn’t private, every single person in the tree is.

What could be causing this? In other words, how do I fix it? That’s not AT ALL what I intended.

Let’s Check the Privacy Settings

The first thing to do, of course, is to check the settings – so I signed in to John’s account.

I checked the privacy settings, located under Account Settings just below the user name of the kit, after you sign in.

According to the Privacy and Sharing settings, John’s tree is not private.

click to enlarge

That seemed odd, so I checked John’s tree myself. It looks fine to me, so I wonder what might be wrong?

click to enlarge

Nothing is showing as private from John’s perspective from within his account.

I decided to send Ned a direct sharing link to see if that made any difference.

The link I shared with Ned made no difference, but reading the information in the red box did! Yay for documentation!

I had not filled in the birth or death dates of the people in question or marked them as deceased. Yes, I know – my bad.

I clicked on the profile and then “View Profile” to verify.

Sure enough – no dates. To edit the profile, click on the pencil.

In order to cause the death date and death location fields to display, you must check the “Deceased” box which then turns blue.

Even if you don’t know the death date or location, marking the person as deceased allows their information to be displayed, such as their name, and NOT to be marked as private.

If you do NOT click the deceased box, the person’s profile WILL be marked “private” and will not be shown to anyone except you, the tester, if you sign in. You’ll have no idea that it isn’t showing to other people when you had intended to share all along.

click to enlarge

I marked each person as deceased and added death dates and locations while I was working on the tree.

Did that take care of the problem?

Let’s take a look from Ned’s perspective.

click to enlarge

Sure did.

In order for people to display, you need to kill them off, again😊

Tree Privacy

Every vendor has a combination of features that control tree privacy and security. You will be able to mark the entire tree private or shareable. You may be able to make it searchable, or not, depending on the vendor.

No vendor will display known living people to others – but the calculations they use to determine who may be living, unless you specifically mark them as deceased, will vary.

Be sure to check all of those factors, and find a way to view the tree from someone else’s perspective to check and be sure it’s functioning the way you expect.

I would never have known that all of John’s ancestors were private if Ned hadn’t contacted me.

At Family Tree DNA, if you view your own tree and you notice that neither dates nor question marks appear in the date field on the pedigree page – that means you have not marked these people as deceased – so no information for them will show to anyone else.

If you see any dates or question marks beneath the names of people on your tree – then that individual’s profile will show and is not private, unless you have marked the entire tree as private.

Check your trees to see if you have an unknown issue. Those valuable trees provide critical information to your matches. They may not contact you to ask why your tree is private – in fact – most won’t. They assume it’s a choice you meant to make.

Be sure you’re not unintentionally driving cousins away. You never know who’s going to have that crucial piece of information or photo, and you want all of your cousin-bait to function as intended!

Ancestry Releases Updated Ethnicity Estimates – Hope You Still Have Your Kilt!

Ancestry has been rolling out their new DNA ethnicity results over the past couple of weeks. By now, pretty much all customers have updated results.

When you sign on and click on your DNA tab, you’ll see a message at the top that tells you whether you have new results or they are coming soon.

I wrote about how ethnicity results are calculated in the article, Ethnicity Testing – A Conundrum. You might want to take a minute and read the article because it applies to methods generally and is not specific to any one vendor.

Ethnicity analysis is quite accurate at the continental level, plus Jewish, but less so within continents like Europe. Your results will vary from vendor to vendor and from update to update with the same vendor over time.

To be very clear, your DNA doesn’t change – and neither does your genealogy, obviously – but the evaluation methods used by various vendors change as more people test, reference populations grow, and the vendors improve their algorithms.

Of course, “improve” is subjective. Changes that “improve” one person’s results have the exact opposite effect on other people.

The Eye of the Beholder

Every time vendors release new population or ethnicity results, everyone runs to check. Then – queue up either “they finally got it right” or teeth gnashing! 😊

Everyone hopes for “better” results – but expectations vary widely and how people determine what “better” means to them is quite subjective.

So yes, the accuracy of the results is truly in the eye of the beholder and often related to how much genealogy they’ve actually done. Surprises in your genealogy can equal surprises in your ethnicity too.

Quantitative Analysis

First, let’s be very clear – you do NOT inherit exactly half of the DNA of each of your distant ancestors in each generation. So you might have NO DNA of an ancestor several generations back in time and multiple segments contributed by another ancestor in the same generation. I wrote about how inheritance actually works in the article, Concepts: Inheritance.

Obviously, if you don’t carry a specific ancestor’s DNA, you also don’t carry any genetic markers for any portion of their ethnic heritage either.

Measuring

The best you can do in terms of ancestral ethnicity percentage expectations is to methodically analyze your tree for the geographic and ethnic heritage of your ancestors.

I explained how I calculated realistic ethnicity estimate percentages in the article, Concepts – Calculating Ethnicity Percentages.

In summary, I made a spreadsheet of my 64 great-great-great-great-great-grandparents, each of which, if the DNA was divided in exactly half and passed to the next generation, would contribute 1.56% of my DNA.

Vendors can typically measure geographically-associated DNA less than 1%. At some point, however, the segments are simply too small to reliably identify and associate with a geographic location or population.

Over time, how different vendors refer to and label different parts of the world both vary and change.

Region Names and Ancestral Assignment

I created a spreadsheet where I track both my “expected” DNA based on my genealogy and the amount of reported DNA from that region by each vendor. As I added vendor results, I sometimes had to add categories since their categories aren’t exactly the same as mine. You’ll observe this in the following sections.

You might notice the “inferred” category. I wrote about this in the Calculating Ethnicity Percentages article, but the inferred locations stem from situations like an unknown wife of a man who is living in England or Germany. We can probably infer that they are from that same country.

In the US, an earlier era spouse’s ethnicity might be inferred from marrying a Scot’s-Irish person, living in a Scots-Irish community or being a member of a Scots-Irish church, for example. Chances are very high that a Scots-Irish man’s wife is also from the “British Isles” someplace.

When creating my spreadsheet, I was intentionally conservative in my genealogical estimates.

Ancestry Update in General

Are there any trends or themes in this most recent Ancestry update? As a matter of fact, yes.

Everybody’s Scottish it seems. I hope you didn’t trade your kilt in for that liederhosen a few years ago, because it looks like you just might need that kilt again.

In fact, Ancestry wrote a blog article about why so many people now have Scotland as an ethnicity location, or have a higher percentage if they already showed Scotland before. I had to laugh, because let me summarize the net-net of the Ancestry article for you, the British Isles is “all mixed up,” meaning highly admixed of course. That’s pretty much the definition of my genealogy!

Another theme is that many testers have Scandinavian origins again.

Back in 2012, Ancestry had a “Scandinavian problem,” and pretty much everyone was Scandinavian in that release, even if they had nary a drop of Scandinavian ancestry. And no, not every person has an unknown paternity event and if they did, the Scandinavians cannot possibly be responsible for all of them. The Viking prowess was remarkable, but not THAT remarkable.

Eight years later, Scandinavian is back.

So, how did Ancestry do on my percentages?

Well, I’m Not Scottish…

In the greatest of ironies, I now show no Scottish at all. My calculations show 5.46%, and it’s probably higher because I descend from Scots-Irish that I can’t place in a location.

I guess I need to turn in my Campbell tartan along with a few others.

I do, however, have Norway back again, but no Scandinavian genealogy.

This chart shows all of the Ancestry updates over time, including this latest, plus a range column for this update.

In addition to the 2020 percentage numbers, I’ve included the ranges shown by Ancestry in the far right column for the 2020 update.

Ranges

When viewing your own results, be sure to click on the right arrow for a population to view the range.

You’ll be able to view the range and additional information.

In this case, Ancestry is confident that I have at least 35% DNA from England & Northwest Europe, and perhaps as much as 41%.

You’ll note that my range for the questionable Scandinavia is 0-5. The only two ethnicities that have ranges that do not include zero are England & Northwestern Europe and Germanic Europe.

My Opinion

I know that I have Native American heritage and that it’s reflected in my ethnicity – or should be.

23andMe results, below, shows me the chromosome locations of Native American segments, and when I track those segments back in time, they track to the ancestors in the Acadian population known to have married Native American partners as reflected in church records. Those ancestors were proven as Native through Y and mitochondrial DNA of their descendants which you can view in the Acadian AmerIndian DNA Project, here.

I wrote about using ethnicity segments identified at 23andMe with DNAPainter to triangulate ancestors in the article, Native American and Minority Ancestors Identified Using DNAPainter Plus Ethnicity Segments.

For me personally, including my Native heritage in my ethnicity results is important. I can’t “do” anything much with that at Ancestry, other than view my match’s shared ethnicity. Since my Native heritage doesn’t show at Ancestry, I can’t use it at all genetically.

Why is this important? Looking at a match on my Acadian line and seeing that we share at least some Native heritage MIGHT, just MIGHT be a hint about a common ancestor. Of course, that’s just a clue, because we might both be native from different sources. If my Native ethnicity is missing at Ancestry, I can’t do that. It’s worth noting that in 2017, Ancestry did report my Native heritage and other vendors do as well.

23andMe provides detailed, downloadable, segment information that translates into useful genealogical information. FamilyTreeDNA has announced that they will be providing ethnicity segment information as well after their new myOrigins release.

The Big 4

How do the Big 4 vendors stack up relative to my genealogy and ethnicity?

And for Native American heritage?

I took the liberty of highlighting which vendor is the closest to my estimated genealogy percentages, but want to remind you that these percentages will only be exactly accurate if the DNA is passed exactly in half in each generation, which doesn’t happen. Therefore, my genealogy is an educated estimate as well. Still, the results shouldn’t be WAY off.

An appropriate sanity check would be that my genealogy analysis and the DNA ethnicity results are relatively close. Many people think they are a lot more of something because those are the family stories they heard – but when they do the analysis, they realize that they might expect a different mixture. For example, my aunt told me that my paternal grandmother’s Appalachian family line was German and Jewish – and they are neither. However, German and Jewish lived in my head for a long time and that was what I initially expected to find.

What’s Next?

Both MyHeritage and Family Tree DNA are slated to release new versions of their population genetics tools – so you’ll be seeing new estimates from both vendors “soon.” Both announced at RootsTech they would deliver new results later in the year, and while I don’t have a release date for either vendor – keep in mind that both FamilyTreeDNA and MyHeritage have brought new labs online from scratch in record time in a humanitarian effort to fight Covid. This critically important work has assuredly interrupted their development schedules. You can read about that here and here.

Kudos to both vendors. Ethnicity can wait.

Deleting DNA Results or Closing Your Account Does NOT Automatically = Destroying Your Original DNA Sample

First and foremost, I want to state unequivocally that I am NOT advocating closing your account at any of the testing vendor sites. That’s not the purpose of this article. In fact, I encourage everyone to use each tool to extract every drop of information possible.

The purpose is to educate and inform you that IF you close your account and/or delete your DNA RESULTS from your account, even if the vendor in question says that the action is irreversible and you will need to resubmit a new sample and purchase a new test if you change your mind, that does NOT necessarily mean that your physical DNA sample itself will be destroyed unless you take separate action to request sample destruction. It also does not automatically reverse any previously-granted research permissions.

Many people presume that if they delete their results and/or close their account, that automatically means that their original spit or swab sample is destroyed – and that’s not necessarily true.

First, we need to understand the difference between:

  • A DNA sample
  • A DNA raw data results file, also referred to as a download file
  • DNA matches or a match file

The Difference Between a DNA Sample, Results and Download Files, and Matches

There are three distinct parts of the DNA testing process that people often confuse. It’s important to understand these distinct pieces because you interact with them differently and vendors do as well. In other words, deleting your DNA results file, or closing your account does not necessarily mean that your original sample is destroyed unless you request (and confirm) that separately.

DNA Sample – The DNA sample itself is the swab or vial of spit that you submit to the vendor for processing. That sample is sent to a lab where DNA is extracted and processed on a specific DNA chip that produces a file with roughly 700,000 locations for autosomal tests.

After your DNA results are processed and the vendor knows that they do not need to rerun your sample, how or if your DNA sample is stored, and where, is a function of each specific vendor and their policies.

One vendor, Family Tree DNA archives your DNA sample vials for 25 years as a free benefit so that you (or your heirs should you pass away) can order additional products or upgrades. FamilyTreeDNA offers various levels of Y DNA and mitochondrial DNA testing along with autosomal (Family Finder) results – so there are several upgrade avenues.

This short article, 4 Kinds of DNA for Genetic Genealogy, explains the difference between various kinds of DNA tests.

It’s less obvious why a vendor who does not offer genealogical DNA products other than autosomal testing would retain a customer’s actual DNA sample. The other three vendors, while they don’t currently offer additional genealogy DNA products, do offer health upgrades and purchase options. They may be retaining samples so that their customers could potentially upgrade and they would have a sample on-hand to rerun, if necessary.

Both MyHeritage and 23andMe offer a combined ancestry/genealogy plus health product initially, or customers can purchase the health add-on later. FamilyTreeDNA offers a high-end comprehensive Exome health product for existing customers, the Tovana Genome Report, but it’s a different test altogether and requires a fresh DNA sample.

Furthermore, both Ancestry and 23andMe either conduct health/medical research internally and/or participate in research partnerships with outside entities and may be hoping that their customers will opt-in to research.

Regardless of the underlying reason why, keep in mind that your actual sample is likely being archived someplace, assuming there is any left after processing, unless you request that your sample be destroyed.

Refer to each vendor’s Terms and Conditions, their Privacy Policy along with any other linked documents to gain insight into how each vendor operates. Furthermore, one of those documents will provide instructions for how to request the destruction of your actual DNA sample, should you choose to do so.

All vendors change the contents of their Terms and Conditions along with other legal documents from time to time, so be sure to refer to the current version.

The DNA sample itself is NOT the same thing as the output from the processing, which is the DNA raw data results file.

DNA Raw Data Results File – The DNA results file contains only a small fraction of the three billion locations found in the human genome. Autosomal DNA tests include only about 700,000 (plus or minus) selected locations produced by the chip the vendor is utilizing. The output of the laboratory process is referred to as a raw data file or the DNA results file. People sometimes refer to this as the download file as well, because it’s the file you can download from each vendor.

The results in a raw data file look like this:

When you download and transfer your file from one vendor to another, the raw data file is what you are transferring. You can find instructions for downloading your data file from each vendor, here.

  • The DNA raw data or download file is NOT your actual DNA, which is what is extracted from the liquid in the vial.
  • The raw data or download file is NOT a list of your matches, which may or may not be a separate file available for downloading, depending on the vendor.

The raw data file only contains letters representing your two genotyped nucleotides (T, A, C or G) for the rsid (accession #) for each genetic address or position tested. Each genetic address contains two SNPs, or single nucleotide polymorphisms. You don’t need to understand the details, just that one nucleotide at that address is received from your mother and one from your father.

The example above shows my first 4 locations in my raw data file. You can see that I received an A from both parents at the first two locations, and a G from both parents and the second two locations.

Match File

The values in your DNA results file are compared to other people in the vendor’s database. If enough contiguous locations match, typically more than 500 matching SNPs, plus additional cM (centiMorgan) threshold match criteria, shown below, you are determined to be a match with that other person. You will each be placed on the other person’s match list, and the vendor will then provide additional processing based on the signature features they offer to their clients.

Of the four main vendors, three, Family Tree DNA, MyHeritage and 23andMe allow customers to download a match file in spreadsheet format that provides additional information about each match. Ancestry, unfortunately, does not.

You cannot upload your match file to other vendors – only your raw data file gets uploaded which the vendor then processes in the same way they would if you had tested at their company.

If someone on your match list wants to be included in the database at another vendor, they will either need to test at that vendor or transfer their file to that vendor. Every vendor has people in their database that the other vendors don’t have, so it behooves all genealogists to be in each of the four databases either by testing directly or uploading their raw data files as a transfer.

Of the four main vendors, FamilyTreeDNA and MyHeritage both accept transfers from other vendors and provide free matching, but 23andMe and Ancestry do not. Note that both FamilyTreeDNA and MyHeritage do charge for advanced features, $19 and $29, respectively, but in both cases, it’s significantly less than the cost of a test.

Deleting Results and Closing Accounts

Again, I am NOT advocating that anyone should close accounts at any vendor. In fact, I would discourage DNA deletion. Some people delete their DNA or close their accounts when other options would better serve their purposes. However, if you decide to do so, you need to be aware of the following:

  • If you have a genealogical tree/records research account at Ancestry or MyHeritage, you can delete your DNA results but maintain your genealogy research account, if you desire. You will lose the benefits of having a DNA test at that vendor if you delete your DNA test.
  • At those two vendors, if you delete your DNA, that does not automatically affect the genealogy side of your account except for combined features like ThruLines at Ancestry and Theories of Family Relativity at MyHeritage.
  • If you DOWNLOAD your DNA file, that does NOT delete the file at the original testing vendor unless you do so separately. Downloading only means that you download a copy of the file. Your original raw data results file is still at the vendor, UNLESS YOU CHOOSE TO DELETE YOUR RESULTS. Do not delete your results file unless you want to lose your matches and no longer participate in DNA testing or DNA-related features at that vendor.
  • If you are planning to delete your DNA results at a particular vendor, download a raw data file first, and verify that the file works correctly by uploading the file to one of the vendors that accepts transfers. Save the raw data file permanently on your computer. This preserves at least some of your testing investment and allows you to utilize your DNA results file elsewhere.
  • If you delete your DNA results at any of the major vendors, you cannot restore the results file at that vendor without repurchasing and resubmitting a new DNA test. For vendors who accept transfers, you could potentially re-upload your file as a transfer, but you would need to pay for advanced features.
  • If you delete your DNA results at vendors who do NOT offer additional genealogical research services, meaning at 23andMe and Family Tree DNA, there is no reason to maintain an account at that vendor.

If you delete your results or close your account at any vendor, it DOES mean that:

  • The DNA result you’ve deleted along with corresponding matches and other features are permanently gone. You cannot change your mind. Delete=permanent.
  • At FamilyTreeDNA, you can delete one kind of DNA test without deleting all types of DNA tests for a particular individual. For example, you could delete a Y DNA result but not delete mitochondrial or the autosomal Family Finder test.
  • You will have to pay to retest should you change your mind.

If you delete your results or close the DNA portion of your account, it DOES NOT necessarily mean that:

  • Your DNA sample is destroyed.
  • You’ve revoked any permissions previously given for participation in research.

You will need to perform both of these tasks separately and independently of deleting your DNA file at a vendor and/or closing your account.

Every Vendor is Different

The process of requesting sample destruction and revoking research permissions is different at each vendor, with or without closing your account.

Every vendor’s terms and conditions are separate and different. Some vendors may automatically close your account if you request sample destruction, and others won’t. Some may automatically delete your sample if you close your account, but I know for certain that’s not uniformly true.

Terms and conditions, as well as standard procedures, change over time as well.

I’m not telling you which vendors operate in which ways, because this article will someday be dated and vendor policies change. I don’t want to take the chance of leading someone astray in the future.

Therefore, if you wish to have your sample destroyed and/or revoke any research permissions previously granted, I strongly suggest that you call the vendor’s customer support and convey specifically what you want, and why. The vendor may offer alternatives to achieve what you desire without deleting your sample and account.

To delete your sample and/or account, you may need to provide your request in writing.

Request verification in writing that your sample has been destroyed and that any previously granted research authority/permission has been rescinded.

Research Permission

Please note that you can rescind previously granted research permission WITHOUT affecting your account in any other way. However, the reverse is not true – deleting your sample and closing your account does not automatically rescind previously-granted research permission.

You can only rescind permission for future research, not research already underway or completed that includes your DNA and corresponding answers to research questions.

Extra Steps

I hope you will continue to enjoy the results of your DNA tests for years to come. New features and benefits are added regularly, as are new matches – any one of which has the potential to break down that pesky brick wall. Equally as important, at least to me, is the legacy I’m leaving with my combined tree, DNA, and research work for future generations.

However, what’s right for me may not be right for you. If you make a different decision, be sure that you fully understand the different parts of DNA testing along with the various options and steps you may need to take to achieve your goal.

23andMe Genetic Tree Provides Critical Clue to Solve 137-Year-Old Disappearance Mystery

DNA can convey messages from the great beyond – from times past and people that died long before we were born.

I had the most surprising experience this week. It began with receiving an email with the sender name of my long-time research buddy, cousin Garmon Estes.

It’s all the more surprising because not only did Garmon never own a computer, despite my ceaseless encouragement, he passed over in 2013 at the age of 85. So, imagine my shock to open my email to see a message from Garmon. Queue up spooky music😊

As it turned out, Garmon’s nephew is also Garmon. I had communicated with the family off and on over the years since the death of Garmon the elder. Garmon, the younger, had written to tell me that the second “great brick wall” that haunted his Uncle Garmon had fallen – and how that happened, thanks to DNA.

Garmon, the Elder

Estes Garmon

Garmon Estes, the elder

I first met Garmon the elder, via letter, back in the 1970s or maybe early 80s. He was an experienced genealogist and I was beginning.

At that time, Garmon had been chasing the identity of the father of our common ancestor, John R. Estes, for decades, and I was just embarking on what would become a lifelong adventure, or perhaps it could better be called an obsession.

John R. Estes had moved from some unknown location to Claiborne County, Tennessee with his wife and family about 1820. That’s pretty much all we knew at that time. Garmon had spent decades before the age of online records researching every John Estes he could find. I can’t even begin to tell you how many John Esteses existed that needed to be eliminated as candidates.

Garmon lived in California, far from Tennessee. I lived in Indiana, then Michigan – significantly closer. He began caring for his ill spouse, and I began traveling to dusty courthouses, sometimes reading musty books page by yellowed page, extracting everything Estes. Garmon worked from his local Family History Center when he could and wrote letters.

Between our joint sleuthing and many theories that we both composed and subsequently shot down, we narrowed John R. Estes’s location of origin to Halifax County, Virginia. However, there were multiple John Esteses living there at the same time, about the same age, none using middle initials reliably, and some not at all. How inconsiderate!

I began perusing every possible record. I had eliminated some Johns as candidates, most often because they clearly remained in the community after our John had moved to Claiborne County. Late one night, in our local family history center, I found that fateful clue – John R. Estes noted as (S.G.) short for “son of George,” on just one tax list. All it takes is that one gold-nugget record.

It was after 10 PM when I left the Family History Center and even later when I got home. I debated whether I should call Garmon or not, but I decided that indeed, he would want to know immediately, even if I did call at an inconvenient time or wake him up.

The discovery of John’s father, of course, opened the door for much more research, and it solved one of Garmon’s two brick walls that had haunted his genealogy life.

He never solved the second one, but it wasn’t for lack of trying.

What Happened to Willis Alexander Garmon Estes?

Willis Alexander Garmon Estes was born on December 21, 1854, in Lenoir, Roane County, TN. His nickname was Willie.

Willie married Martha Lee Mathis in 1874 and they had 4 children beginning with the first child born the next year in Roane County. Sometime between 1875 and the birth of the second child in 1877, they migrated to Greenwood, Wise County, Texas where their next two children were born in 1877 and 1881.

Martha was pregnant for their fourth child in 1883 when something very strange happened. Willie disappeared, and I do mean literally and completely. Just poof, gone.

Not sure what to do, Martha’s father, who lived in Missouri, went to Texas to retrieve his pregnant daughter and her children and took her and the children home to Missouri where their last child was born that September.

Willie was only 28 when he vanished. The family, of course, had many stories about what happened. Texas at that time was pretty much the “wild west” and the stories about Willie reflected exactly that.

Texas was sometimes the refuge of outlaws and shady characters. One story revealed that Willie had shot a man back in Tennessee and the family fled to Louisiana, then Texas. Of course, that doesn’t tell us why he disappeared in Texas, but it opens the door to speculation and casts doubt on his character, perhaps.

Another story was that he was shot by Indians.

A third story stated that Willie settled in Indian Territory north of the Red River, now Oklahoma, and that he had an altercation with an Indian over the supposed theft of firewood, although who was accusing who was unclear. Willie shot the Indian, then had to flee for his life, leaving his pregnant wife and children as a posse of Indian Police surrounded his house. Willie supposedly promised Martha that he would return, but never did. It was reported that he was shot in Mexico, but no further details emerged.

Aren’t these just maddeningly vague???

Yet another story was that Willie headed for the goldfields of California, struck it rich, and was murdered on the way back home. The details varied, but one version had him murdered by a traveling companion on the trail. Another had him becoming ill and dying in a hospital in St. Louis where his wife went to search for him, to no avail. That might explain why she went back to Missouri, Garmon postulated. And yet a third version was some hybrid of the two where “someone” tried to find Willie’s family for years to reveal what had happened, and where, but was never successful. Of course, how did the family know about this if the mystery person was unable to find the family? But I digress.

Garmon desperately wanted to solve that mystery. He wanted closure.

I didn’t realize that the genealogy bug had bitten Garmon’s nephew too, but it clearly has. Garmon would be so proud.

With Garmon the younger’s permission, I’m publishing “the rest of the story,” Connecting the Dots, as written by Garmon the younger, with a few technical interjections from me involving DNA from time to time.

Connecting the Dots

In 2015, My dad Richard Estes, my brother Corey Estes, and I took a trip to Texas and Oklahoma to see if we could find out more about Willis Alexander Garmon Estes’ disappearance.

Estes greenwood

We visited Greenwood, Texas and nearby Decatur where we looked at historical records at the Wise County Clerk Office. We also went up to Oklahoma City to see the state archives and to Tishomingo to look at any records that might be available.

Estes Oklahoma history.png

Interestingly enough, we did not find any clues as to the disappearance of Willis Alexander Garmon Estes. There were no newspaper articles or criminal records concerning any incidents with Willis Alexander Garmon Estes. The only new information that we found was a couple of land deeds showing that Willis Alexander Garmon Estes’ brother Fielding had bought and sold land in Wise County during the time that Willis Alexander Garmon Estes was living in Greenwood.

We left empty-handed on our trip but our curiosity remained strong and we began talking to each other about going on another trip to Tennessee to speak with Estes family members in Loudon County to see if they might know something about Willis Alexander Garmon’s disappearance.

DNA Testing

In December of 2018, my wife, children, and I had our DNA tested using the service 23andMe. We received test results within a month of sending in saliva samples. The results did not reveal anything unusual.

Fast forward to October 2019. 23andMe introduced a new Family Tree feature that automatically creates a family tree based on the DNA results that you share with relatives in 23andMe. This was a fascinating feature and I noticed that all of my family members were automatically placed into the correct position on the family tree without me having to do anything.

[Roberta’s note – this is not always the case, so don’t necessarily expect the same level of accuracy. The tree is a wonderful innovative feature, just treat family placement as hints and not facts.]

Every few weeks as more and more people had their DNA tested on 23andMe, new relatives were added to the family tree.

In February 2020, I noticed something interesting under the location of Willis Alexander Garmon Estes on the family tree. A woman by the name of Edna appeared as a descendent of Willis Alexander Garmon Estes. The first thing I did was to try and get in contact with her on 23andMe. No luck. Next, I thought maybe she was the descendent of one of Willis Alexander Garmon’s sons (James, John, or George). However, after researching the descendants of each of those lines, Edna’s name did not appear.

The next step I took was to look up as many Ednas by that last name on ancestry.com as I could find and trace their ancestry back to see where it led.

There were two Ednas by that last name in the United States whose age matched the one on 23andMe. I traced both of their ancestry lines back to the 1800’s. Neither one had Willis Alexander Garmon Estes as an ancestor.

Breakthrough

During the middle of March 2020, when I was quarantined at home from work due to the COVID-19 virus, I took another look at Edna’s family lines. I noticed there was a gentleman by the name of James Henry Houston mentioned as an ancestor.

The interesting thing about James was that he was born on the same day, same year, and in the same county as Willis Alexander Garmon Estes. James Henry Houston was born on December 26, 1854 in Loudon County, Tennessee. This seemed like possibly more than a coincidence, so I dived into the data a little bit more.

I looked at federal census records to find out more about James Henry Houston’s past. Strangely there were no official records of him until May 12, 1889 when he married Allie Ona Taylor in Erath, Texas. Normally, if someone is born in 1854, they would show up in one of the federal census records of 1860, 1870, or 1880. James Henry Houston does not show up in any official federal census records until 1900.

According to ancestry records, James Henry Houston married Allie Ona Taylor in 1889 and resided in the Hood County region of Texas until 1910. During this time, he raised 8 children with his wife Allie.

In 1920, the federal census placed him and Allie in Whitehall, Montana. The last federal census he appears in is 1930. He lived in Pomona, California where he died in 1933 at the age of 78.

At this point, I thought it was highly likely that James Henry Houston and Willis Alexander Garmon Estes were the same person. If my hunch was correct then a photo of James Henry Houston would most likely show a resemblance to his son, my great grandfather John Alexander Estes.

Estes James Henry Houston

The photos above show a remarkable similarity in the eyes, nose, mouth, and facial structure between the two men. To me, the photo and historical evidence is enough to conclude that Willis Alexander Garmon Estes is James Henry Houston.

Garmon’s Concluding Thoughts

As I reflect on the fact that Willis Alexander Garmon Estes renamed himself James Henry Houston and moved from Wise County down to Hood County, Texas – approximately 60 miles distance to marry and raise a new family, many more questions come to mind.

What exactly happened to cause Willis Alexander Garmon Estes to leave his wife and children behind? Was it simply a marital dispute or did it involve a criminal offense and running from the law as was mentioned in the family lore?

Did my great grandfather know that his father lived in Pomona in 1930, which was only 6 miles away from where he was living in Rancho Cucamonga? Were there other family members that knew what happened but promised not to tell anyone else? We may never know.

Finally, I want to add one more piece to the story that I found fascinating. On ancestry.com, many of the family trees for James Henry Houston state that the mother and father of James Henry Houston was Jennie Bray and Henry Houston. No information is given for their birthdates or where they came from. The mother and father of Willis Alexander Garmon Estes was Jennie McVey and William Estes. The names Jennie Bray and Jennie McVey are very similar. In order to hide his true identity, James Henry Houston would have to make up a surname for his father since he called himself Houston, not Estes. Willis Alexander Garmon Estes had a brother named John Houston Estes. This might explain why James Henry Houston chose to use the surname Houston rather than another name.

Congratulations Garmon

I know this made Garmon the elder puff up with pride for Garmon the younger’s sleuthing skills and leap for joy at the solve. Garmon, the elder, had two main genealogy goals throughout his entire life. One was solved while he was living, but it took another generation to solve this one.

Great job, Garmon!

About the 23andMe Genetic Tree

23andMe is the only vendor to construct a “trial balloon” genetic tree based only on how the tester matches people and how they do, or don’t, match each other. This occurs with no input from testers in the form of genealogical trees of identifying how people are related to the tester.

Family Tree DNA has Phased Family Matching, MyHeritage has Theories of Family Relativity, and Ancestry has ThruLines which all do some sort of DNA+tree+relationship connectivity, but since 23andMe does not support user-created or uploaded trees, anything they produce has to be using DNA alone.

On one hand, it’s frustrating for genealogists, but on the other hand, there is sometimes a benefit to a different “all genetic” approach.

Of course, the only information that 23andMe has to utilize unless your parents have tested is how closely you match your matches and how closely your matches match each other. This allows 23andMe to place your matches at least in a “neighborhood” on your tree, at least approximately accurate, unless your parents are related to each other and that shared DNA causes things to get dicey quickly.

I wrote about 23andMe’s new relationship triangulation tree when it was first introduced in September 2019, nearly a year ago, here. The launch was rocky for a number of reasons, and if you’ve done genealogy for a long time, your research goals are likely to be further back in time than this 4 generation relationship tree will reveal.

23andMe tree

Click to enlarge

This is what my relationship tree looked like at the time the function was launched. You’ll note that 23andMe places relationships back in time 4 generations, to your great-great-grandparents, meaning that you might have 3rd or even 4th cousins showing up on your genetic tree.

I initially had a total of 18 people placed on my tree, with 3 being close family, 4 being accurate, 4 unknown, 1 uncertain and 6, or one third, inaccurate.

Keep in mind that 23andMe doesn’t make any provision to accommodate or take into account half-relationships, like half-brother or half-sister, either currently or historically. Therefore, descendant placement predictions can be “off” because half-siblings only carry the DNA from one common parent, instead of two, making those relationships appear more distant than they really are.

In Garmon’s case, his great-great-grandfather is the ancestor who was MIA, so the genetic tree has the potential to work well for this purpose.

Today, my tree looks somewhat different, with only 14 people displayed instead of 18, and 6 waiting in the wings to see if I can help 23andMe figure out how and where to place them.

Since the initial launch, customers have been given the opportunity to add their ancestors’ names to their nodes. This works just fine so long as nobody married more than once and had children from both marriages.

Here’s a closer image of the left-hand side of my tree where I’ve super-imposed the location of Willis Alexander Garmon Estes and Edna, as they are related to Garmon the Younger, at bottom right. Ignore the other names – I only utilized my own tree for an example tree structure.

One more generation and it’s unlikely that 23andMe would have made the connection between Edna and Garmon the younger.

Not only does this illustrate the perfect reason to test the oldest generations in your family, but also never to ignore an unknown match that seems to be within the past 3 or 4 generations. You never know what mysteries you might unravel.

Four generations actually reaches back in time quite substantially. In my case, my great-great-grandparents were born in 1805, 1810, 1812, 1813, 1815, 1816, 1818 (2), 1820, 1822, 1827, 1829, 1830, 1832, 1841 and 1848.

If you have mysteries within your closest 4 generations to unravel, the genetic tree at 23andMe might provide valuable clues, but only if you’re willing to do the requisite work to figure out HOW these people match you.

You can’t transfer your DNA file TO 23andMe, so if you want to have your results in the 23andMe database, you’ll need to test there.

Acknowledgments: Thank you to Garmon Estes, the younger, for generously sharing this story and allowing publication. My heart was warmed to see your generational research trip.

Thank you to Garmon Estes, the elder, for being my research partner for so many years. You can finally RIP now, although somehow I suspect you already have these answers.

Search Techniques for Y and Mitochondrial DNA Test Candidates

I utilize DNA matches in various ways, some of which are a little unusual. In many cases, I mine autosomal DNA matches to search for people whose Y and mitochondrial DNA can provide descendants, including me and them, with additional insights into our common ancestors.

Y and mitochondrial DNA connects testers to their ancestors in ways that autosomal cannot. It’s a different type of DNA, not combined with the DNA of the other parent, so it’s not diluted and halved in each generation like autosomal DNA. Y and mitochondrial lines each descend from only one ancestral line, rich in historical information, with the ability to reach far back in time along with the ability to connect testers recently.

You First

The very first thing you can do to further your own research is to test yourself in three ways:

  • Autosomal DNA – Test at all 4 primary testing vendors, meaning FamilyTreeDNA, MyHeritage, Ancestry and 23andMe. The reason for testing at (or transferring to) multiple vendors is because they each have a unique focus and tools. Perhaps more importantly, they each have different people in their databases. Each testing company has benefits. FamilyTreeDNA has people who tested as long as 20 years ago and are no longer available for testing. MyHeritage has many European testers and you’ll find matches there that you won’t find elsewhere if your ancestors came from Europe. Ancestry has the largest database, but fewer advanced tools.
  • Full Sequence Mitochondrial DNA Available at FamilyTreeDNA, this test allows focus solely on your matrilineal line, meaning your mother’s mother’s mother’s line directly without confusion introduced by DNA from other lines.
  • Y DNA – For males only, also available at FamilyTreeDNA, provides focus on the direct patrilineal, or surname, line.

Obviously, if you haven’t upgraded your own Y and mitochondrial DNA tests to the highest level possible, the first thing you can do is to test or upgrade to the highest level where you receive the most refined amount of information.

(There’s a sale at FamilyTreeDNA right now, lasting until August 31, 2020, so it’s a great time to upgrade or order Y and mitochondrial. Check it out here.)

Different Kinds of DNA Serve Different Genealogical Purposes

Let’s look, briefly at how the various types of DNA tests benefit genealogy. Autosomal tests that you and family members can take will help you find other family members to test for specific Y and mitochondrial DNA lines.

Remember that you can test family members in addition to yourself, so if you’re a female, you may want to recruit your father or an uncle or brother to represent your patrilineal line DNA. If you’d like to read a brief article about the different types of DNA and their benefits, 4 Kinds of DNA for Genetic Genealogy is a good resource.

Y and Mito Pedigree.png

In this image, you can see that if you’re a male you can test for both your Y (blue-square) and mitochondrial DNA (red-circle) ancestral lines. If you’re a female, you can test only your mitochondrial DNA because females don’t have a Y chromosome. Both males and females, of course, can test (green) autosomal DNA which reveals a different type of connection to all of your ancestral lines, but with autosomal, you have to figure out which people match you on which lines.

Y and mitochondrial DNA provides you with a different type of information about laser-focused specific lines that you can’t obtain through autosomal testing, and reaches back in time far beyond the curtain when surnames were adopted.

personal pedigree

You personally can only test for the red-circle mitochondrial DNA line, and perhaps the blue-square Y DNA line if you’re a male. Unless you find family members to test for the Y and mitochondrial DNA of your ancestors, you’re leaving valuable information unresearched. That means all those colored boxes and squares that aren’t blue or red.

I’ve solved MANY brick walls using both Y and mitochondrial DNA, often in conjunction with autosomal.

Let’s take a look at each type of DNA testing a little more in-depth, so that you understand how each one works and why they are important to genealogy.

The Specifics

Y DNA – Y DNA descends through the direct male paternal line and is inherited by men only. You match against other Y DNA testers, hopefully finding surname links.

The Big Y test and upgrade at FamilyTreeDNA provides testers with all 111 traditional STR markers, plus another 589+ STRs available only in the Big Y test, plus a scan of the balance of the rest of the Y chromosome that is useful for genealogy. SNP results are increasingly being used for genealogy, in addition to STRs.

SNPs group men into genetic lineages and STRs help with defining and refining the closest generations when matching to each other. Often, the benefits of these two tests overlap, which is why I recommend that males test to the Big Y-700 level which provides 700+ STR markers plus all SNPs with mutations that define ancestral lineages.

Y DNA haplogroups, derived from SNPs, reveal the geographic part of the world where the lineage originated, such as Europe, the Americas, Asia and Africa, as well as a migration path across the continents based on where SNPs are and were historically found. Ancient DNA samples are being added to the database.

If you or a family member took an earlier Y DNA test, you can upgrade to the Big Y-700 today which provides you with matching for both the STR markers and separately, SNP markers, along with other genealogical tools.

You can order or upgrade your Y DNA here. Don’t forget family members accounts you may control. They may agree to have their kit upgraded too.

To upgrade, sign in to your account, and click on your desired upgrade level under Y DNA testing.

Then click on upgrades.

ymt upgrade.png

I wrote about Y DNA in these recent articles:

I have more Y DNA articles planned for the future.

You can search for additional articles by going to the main page of this blog and enter “Y DNA” into the search box for additional articles already published.

Many features such as the matches maps, haplogroup origins and ancestral origins pages are the same for Y DNA results as mitochondrial DNA results. You can view mitochondrial articles here.

Mitochondrial DNA (mtDNA) – Mitochondrail DNA descends through the direct matrilineal line to both sexes of children. Everyone has mitochondrial DNA and it is inherited matrilineally by you from your mother, from her mother, from her mother, etc.

The FMS or full mitochondrial sequence DNA test tests the entire mitochondria that provides information about your direct matrilineal line. Family Tree DNA provides matching, which can sometimes lead to genealogical breakthroughs such as when I identified Lydia Brown, the mother of my Phoebe Crumley and then a couple years later, her mother, Phoebe Cole – via mitochondrial DNA. Those discoveries led us to her mother, Mary Mercy Kent, via genealogy records. All we needed was to punch our way through that initial brick wall – and mitochondrial DNA was our battering ram.

Additionally, you’ll receive a full haplogroup designation which allows you to look back in time before the advent of surnames and identifies the location where your ancestral line came from. For those seeking confirmation of Native American heritage, Y and mitochondrial DNA provides unquestionable proof and doesn’t wash out in time as autosomal DNA does.

Mitochondrial DNA includes haplogroups, matching and other genealogical tools.

You can order or upgrade you or a family member’s mitochondrial DNA here.

To upgrade, sign in to your account, and click on the desired upgrade level.

I wrote several mitochondrial DNA articles and compiled them into a summary article for your convenience.

Autosomal DNA – With autosomal DNA testing, you test once and there’s not an upgrade unless the vendor changes DNA testing platforms, which is rare. Each of the four vendors compares your DNA with all other people who’ve taken that test, or transferred from other companies. They match you with descendants from all of your ancestral lines. While the Y and mtDNA tests look back deeply in time as well as recently on one specific line, the autosomal tests are broad but not deep, spanning all ancestral lines, but limited to approximately 10 generations.

Each autosomal vendor has unique benefits and focus as well as shortcomings. I’ve listed the major points for each vendor relative to searching for Y and mitochondrial
DNA testing candidates. It’s important to understand the advantages of each vendor because it will help you understand the testers you are most likely to find in each database and may help focus your search.

FamilyTreeDNA’s Family Finder

  • Because FamilyTreeDNA archives customer’s DNA for 25 years, many people who tested Y or mitochondrial DNA 20 years ago and are now deceased upgraded to autosomal tests when they became available, or have been upgraded by family members since. These early testers often reach back another generation or so into the past to people born a century ago.
  • Advanced autosomal matching integrates with Y and mitochondrial DNA along with surname and other projects
  • Phased Family Matching provides the ability to link family members that match you to your tree which allows Family Tree DNA to group matches as paternal or maternal by utilizing matching segments to the same side of your family
  • Genetic Affairs, a third-party tool available for testers, builds common trees by reading the trees of your matches and comparing their trees with your own to identify common ancestors.
  • Genetic Affairs builds trees and pedigrees of your matches by searching for common ancestors in your MATCHES trees, even if you have no tree or don’t share those ancestors in your tree. This functionality includes Y and mitochondrial DNA if you have tested. This facilitates discovery of common ancestors of the people who you match, which may well lead you to ancestral discoveries as well.
  • Genetic Affairs offers clustering of your shared matches.
  • DNA file transfers are accepted from other vendors, free, with a $19 one time fee to unlock advanced tools.
  • Family Tree DNA has tested people worldwide, with a few location exceptions, since inception in the year 2000.
  • No direct triangulation, but Phased Family Matching provides maternal and paternal side triangulation when matches can be grouped into maternal and paternal sides.
  • Matches and segment match information are available for download.
  • The great thing about the advanced matching tool at Family Tree DNA is that it facilitates searching for people who match you on different kinds of tests, so it helps determine the potential closeness or distance of Y and mitochondrial relationships.

MyHeritage

Ancestry

  • Ancestry has the largest database, but did not begin testing until 2012 and did not test widely outside of the US/UK for some time. They now sell tests in 34 countries. Their testers are primarily focused in the US, Canada, England, Scotland, Ireland, and diaspora, with some overlap into Europe.
  • Ancestry offers ThruLines, a tool that connects testers whose DNA matches with common ancestors in their trees.
  • Ancestry does not provide a chromosome browser, a tool provided by the other three primary testing companies, nor do they provide triangulation or matching segment location information necessary to confirm that you match on the same segment with other people.
  • Ancestry has issued cease and desist orders to third party tools that perform functions such as clustering, autotrees, autopedigrees or downloading of matches. Ancestry does not provide these types of features for their users.
  • Ancestry does not accept transfers, so if you want to be in Ancestry’s database, you must test with Ancestry.
  • No Y or mitochondrial DNA testing available.
  • Match list is not available for download.

23andMe

  • The primary focus of 23andMe has always been health testing, so many people who test at 23andMe are not interested in genealogy.
  • 23andMe tests are sold in about 50 countries, but not worldwide.
  • 23andMe provides a chromosome browser, triangulation, segment information and a beta genetically constructed tree for close matches.
  • 23andMe does NOT support a genealogical tree either uploaded or created on their site, making tree comparisons impossible.
  • Genetic Affairs AutoCluster works at 23andMe, but AutoTree and AutoPedigree do not because 23andMe does not support trees.
  • 23andMe does make match files available for downloading.
  • No Y or mitochondrial DNA full testing or matching, but basic haplogroups are provided.
  • 23andMe caps matches at 2000, less any matches that have opted out of matching. My matches currently number 1770.
  • 23andMe does not accept transfers from other vendors, so if you want to be in their database, you must test with 23andMe.

Reaching Out to Find Testers

Unfortunately, we only carry the mitochondrial DNA of our mother and only men carry the Y DNA of their father. That means if we want to obtain that DNA information about our other family lines, we have to find people who descend appropriately from the ancestor in question and test that person.

I’ll share with you how I search for people who descend from each ancestor. After finding that person, I explain the situation, why the different kinds of tests are important, and offer a testing scholarship for the Y or mtDNA test at Family Tree DNA if they have not already taken that test. If they’ve tested their autosomal DNA elsewhere. I also explain that they can transfer their autosomal DNA file for free too and will receive new matches.

Here’s an article with links to upload/download instructions for each testing company. Feel free to share.

Each DNA testing company has different features, but you can use all of the companies to find people descended in the appropriate way from each ancestor. It’s easier if you know how to utilize each vendor’s tools to optimize your chances of success. I’m going to step you through the search process with hints and tips for each vendor.

Finding Y DNA and Mitochondrial DNA Candidates at FamilyTreeDNA

Because FamilyTreeDNA tests for both Y and mitochondrial DNA and has for 20 years, you stand a better chance of finding a candidate there who may have already tested, so that’s where I always begin.

Y DNA

Let’s say, for example, that I need to find a male descendant of my Ferverda line in order to ask them to test for Y DNA. The person can be descended from either a close relative, if I know of one, or a more distant relative that I don’t know, but need to find through searching other ways.

Search for Surnames and Projects at Family Tree DNA

First, search the FamilyTreeDNA website for your goal surname among existing testers, and then the appropriate surname project to see if your line has already tested.

ymt ferverda

On the main page, here, scroll down to until you see the prompt, above, and enter the surname. Be sure to consider alternate spellings too.

ymt ferverda search.png

In this case, I see that there is a Ferverda surname project with 18 people, and scrolling on down, that 4 people with this specific surname have tested.

ymt results.png

However, searching for an alternate spelling, the way it’s spelled in the Netherlands, I find that another 10 people have tested.

ymt ferwerda

Of course, some may be females, but they probably know males by that surname.

First, I’m going to check the Ferverda DNA project to see if a Ferverda male from my line has tested, and if so, to what level.

Click on the project link in the search results to see the DNA Project.

ymt admin.png

Note two things. First, the administrator’s name, as you may need this later. If you click on their name, their email address is displayed.

Second, click on DNA Results and select Y DNA if you’re presented with a choice. If the project has a public facing page, and most do, you’ll see something like the following information.

ymt project

Hey look, it’s my lucky day, given that both of these men descend from my ancestor. I happen to know that they have both taken the Big Y test, because I’m the project administrator, but you won’t know that. One way to get an idea is if they have less than the full 111 markers showing, they probably haven’t taken the Big Y, because a 111 upgrade is included in the Big Y test today.

You have three options at this point to contact one of these men:

  • See if the people are on your own autosomal DNA match list, or the match lists of kits from that family that you manage. If so, you can view their email address and contact them. If you haven’t yet tested autosomally, meaning the Family Finder test, at Family Tree DNA, you can transfer autosomal tests from elsewhere, for free, which means you will be viewing matches within hours or a couple days. Otherwise, you can order a Family Finder test, of course.
  • If the person with the Ferverda or Ferwerda surname is not on your Family Finder match list, reach out to the project administrator with a note to the person you want to contact and ask the administrator to forward your email to the project member.
  • If the administrator doesn’t answer, contact Family Tree DNA support and make the same request.

Checking Family Finder, one of those people is on my match list and I’m pretty sure it’s the right person, because when I click on his profile, not only does the haplogroup match the DNA project, but so does the ancestor.

ymt ferverda profile.png

Searching Family Finder

If there isn’t a DNA project match you can identify as your direct line ancestor, you can search your Family Finder matches for the surname to find a male with that surname. If your match has a tree, see if your ancestor or ancestral line is showing, then note whether they have taken a Y DNA test. They may have taken a Y test, but have not joined a project or not entered any “earliest known ancestor.” You can see which tests they’ve taken by looking at the little tabs above their profile on their tree, or on their profile card.

ymt ferverda tree

click to enlarge

Regardless, you’re now in touch with a potential contact.

Don’t dismiss females with that surname, or people who show that surname in their ancestral surname list. Women with the surname you’re looking for may have husbands, fathers, brothers or uncles who descend from the line you are seeking.

ymt search field.png

Utilize Genetic Affairs

My ace in the hole at FamilyTreeDNA is the Genetic Affairs AutoTree and AutoPedigree function.

Genetic Affairs is a third-party tool that you can use to assist with analysis of your matches at FamilyTreeDNA.

ymt genetic affairs

click to enlarge

At Genetic Affairs, selecting AutoTree generates trees where common ancestors of you and your matches, or your matches to each other, are displayed.

Your goal is to identify people descended from a common ancestor either directly paternally through all males for Y DNA or through all females to the current generation, which can be males, for mitochondrial DNA.

This article provides step-by-step instructions for the Genetic Affairs AutoTree and AutoPedigree functions.

Mitochondrial DNA

Mitochondrial DNA lineages are a bit more challenging because the surname changes every generation and DNA projects are unlikely to help.

The AutoTree/AutoPedigree report through Genetic Affairs serves the same purpose for mitochondrial DNA – building trees that intersect with a common ancestor. I generally drop the “minimum size of the largest DNA segment shared with the match” to 7 cM for this report. My goal running this report for this purpose isn’t to analyze autosomal DNA, but to find testing candidates based on how my matches descend from a specific ancestor, so I want to include as many matches as possible.

Family Finder Can Refine Y and mtDNA Information

In some cases, a Family Finder test can refine a potential relationship between two people who match on either Y DNA or mitochondrial. Additionally, you may want to encourage, or gift, specific matches with an upgrade to see if they continue to match you at higher testing levels.

Let’s say that two men match closely on a Y DNA test, but you’d like to know how far back the common ancestor lived.

ymt y matches.png

In this instance, you can see that the second match has taken a BIg Y and a Family Finder test, but the exact match (genetic distance of 0) has not. If the first individual cannot provide much genealogy, having them take a Family Finder test would help at least rule out a relationship through second cousins and would give you at least some idea how far back in time your common ancestor may have lived. If you do match on Family Finder, you receive an estimate of your relationship and can check the match level possibilities using the DNAPainter Shared cM Tool. If they upgrade to the Big Y-700 test, you may be able to differentiate your line from theirs, or confirm when and where a split occurred – or that there is no split.

This same autosomal testing scenario works for mitochondrial DNA.

For people who have taken both tests, Family Finder plus either Y or mitochondrial DNA, the Advanced Matching menu allows you to select combinations of tests and projects to query.

Finding Y and Mitochondrial DNA Candidates at MyHeritage

MyHeritage provides a wonderful tool called Theories of Family Relativity (TOFR) which finds common ancestors between you and your DNA matches, even if the ancestor is not in both trees, so long as a path exists between the two testers’ trees using other trees or research documents, such as census records. Of course, you’ll need to verify accuracy.

ymt tofr.png

At MyHeritage, select DNA Matches, then “Has Theory of Family Relativity.”

ymt mh ferverda

click to enlarge

You can see that I have 65 matches with a Theory of Family Relativity. Additionally, I can then search by surname.

ymt mh ferverda tree.png

click to enlarge

If I am looking for a Ferverda Y DNA candidate, I’ve found one thanks to this TOFR.

If you don’t find a tree where your match descends from your ancestor in the desired way, you can also widen the search by de-selecting Theories of Family Relativity and instead selecting SmartMatchs or shared surname combined with the name of your ancestor. There are many search and filter combinations available.

Let’s look at a mitochondrial DNA example where I’m searching for a descendant of Elizabeth Speaks who married Samuel Clarkson/Claxton.

ymt smartmatches

click to enlarge

In this case, I have one SmartMatch, which means that someone by the name of Elizabeth Speaks is found in my matches tree. I need to look to see if it’s the RIGHT Elizabeth Speaks and if my match descends through all females to the current generation. If so, I’ve found my mitochondrial DNA candidate and I can leave them a message.

You can also view SmartMatches (without a DNA match) from your own tree.

I can go to that person in my tree, click on their profile, and see how many SmartMatches I have. Clicking on 13 SmartMatches allows me to view those matches and I can click through to the connected trees.

ymt mt speaks.png

I can also click on “research this person” to discover more.

If you’re still not successful, don’t give up quite yet, because you can search in the records for trees that shows the person whom you seek. A SmartMatch is only created if the system thinks it’s the same person in both trees. Computers are far from perfect.

ymt mh trees

click to enlarge

Narrow the search as much as possible to make it easier to find the right individual, and then view the trees for descent in the proper manner.

Another wonderful tool at MyHeritage is the Genetic Affairs AutoCluster tool, built-in for MyHeritage users.

ymt mh cluster.png

The above cluster shows that one person carries the surname of Elizabeth’s husband. Viewing the accompanying spreadsheet for the AutoCluster run reveals that indeed, I’ve already identified a couple of matches as descendants of the desired ancestral couple. The spreadsheet shows links to their trees, my notes and more.

ymt cluster ss

Clusters show you where to look. Without the cluster, I had only identified two people as descendants of this ancestral couple. I found several more candidates to evaluate and two mitochondrial candidates are found in this cluster.

Finding Y and Mitochondrial DNA Candidates at 23andMe

23andMe is a little more tricky because they don’t support either uploaded or created user trees which makes finding descendants of a particular ancestor quite challenging.

However, 23andMe attempts to create a tree of your closer relatives genetically. which you can find under “DNA Relatives,” under the Ancestry tab, then “Family Tree” at the top.

I’ve added the names of my ancestors when I can figure out who the match is. Please note that this “created tree” is seldom exactly accurate, but there are often enough hints that you’ll be able to piece together at least some of the rest.

Here’s part of my “created” tree at 23andMe. I’m at far right.

ymt23 tree.png

click to enlarge

If you’re a genealogist, your eyes are going to glaze over about now, because the “people” aren’t in the correct locations – with maternal and paternal sides of the tree swapped. Also, please note, the locations in which they place people are estimates AND 23andMe does NOT take into account or provide for half-relationships.

That said, you can still obtain candidates for Y and mitochondrial DNA testing.

In this case, I’m searching for a mitochondrial DNA candidate for Evaline Miller, my grandfather’s mother or a Y DNA candidate for the Ferverda line.

I can tell by the surname of the male match, Ferverda, that he probably descends through a son, making him a Y DNA candidate.

Both Cheryl and Laura are possible mitochondrial DNA candidates for Evaline Miller, based on this tree, depending of course on how they actually do descend.

I can contact all of my matches, but in the event that they don’t answer, I’m not entirely out of luck. If I can determine EXACTLY how the match descends, and they descend appropriately for mitochondrial DNA, I can view the match to see at least a partial haplogroup. Since 23andMe only uses relatively close matches when constructing your tree, I’m relatively likely to recognize the names of the testers and may have them in my genealogy program.

By clicking on the Ferverda male, I can see that his Y haplogroup is I-Z58. That’s not nearly as refined as the Y DNA information at Family Tree DNA, but it’s something if I have nothing else and he doesn’t answer my query that would include the offer of a Y DNA test at Family Tree DNA.

ymt 23 hap

You can search at 23andMe by surname, but unless your match has entered their ancestral surnames and you recognize surnames that fit together, without a tree, unless your match answers your query, it’s very difficult to determine how you connect.

ymt 23 search.png

You can also view “Relatives in Common,” hoping to recognize someone you know as a common match.

ymt relatives in common

Please note that 23andMe does allow testers to enter a link to a tree, but few do.

ymt tree link.png

It’s worth checking, and be sure to enter your own tree link location.

Finding Y and Mitochondrial DNA Candidates at Ancestry

Ancestry’s ThruLines provides an excellent tool to find both Y and mitochondrial DNA participants.

Ancestry organizes their ThruLines by ancestor.

ymt thrulines

click to enlarge

Select your desired Ancestor, someone whose DNA you seek. Clearly, Y DNA candidates are very easy because you simply choose any male ancestor in the correct line with the surname and look for a male match with the appropriate surname.

In this case, I’m selecting Martha Ruth Dodson, because I need her mitochondrial DNA.

ymt dodson.png

By clicking on her “card” I then see my matches assigned to her ThruLine.

Ymt ancestry thruline

Obviously, for mitochondrial DNA, I’m looking for someone descended through all females, so Martha’s daughter, Elizabeth Estes’s son Robert won’t work, but her daughter, Louisa Vannoy, at left is the perfect candidate. Thankfully, my cousin whom I match, at bottom left is descended through all females to the current generation, which can be male or female, so is a mitochondrial DNA candidate.

Finding Y and Mitochondrial DNA Candidates in Trees in General

I’ve utilized the combination of trees and DNA matches at FamilyTreeDNA through Genetic Affairs, Ancestry and MyHeritage, but you can also simply search for people who descend from the same ancestor based on their tree alone at the vendors who support trees as part of genealogical records. This includes both Ancestry and MyHeritage but also sites like Geneanet which is becoming increasingly popular, especially in Europe. (I have not worked extensively with Geneanet yet but plan to take it for a test drive soon.)

My reason for utilizing DNA matches+trees first is that the person has already been introduced to the concept that DNA can help with genealogy, and has obviously embraced DNA testing at least once. Not only that, with the assist of a Theory of Family Relativity, ThruLine or genetic Affairs automation tools, it’s much easier to find appropriate candidates.

Finding Y and Mitochondrial DNA Candidates at WikiTree

If you reach beyond DNA testing companies, WikiTree provides a valuable feature which allows people to specify that they descend from a particular ancestor, and if they have DNA tested, how they descend – including Y DNA, mitochondrial DNA and autosomal.

Here’s an example on the profile of John Y. Estes at WikiTree, one of my Estes ancestors.

ymt wiki.png

If someone descends appropriately for either Y or mitochondrial DNA line, and has taken that test, their information is listed.

In this case, there are two Y DNA testers and two autosomal, but no mitochondrial DNA which would have descended from John’s mother, of course.

You can click on the little green arrow icon to see how any DNA tested person descends from the ancestor whose profile you are accessing.

ymt wiki compare

Of course, the same surname for males is a good indication that the man in question is descended from that paternal line, but check to be sure, because some males took their mother’s surname for various reasons.

Here’s my line-of-descent from John Y. Estes. I can click on anyone else whose DNA information is listed as well to see how they descend from John. If they descend from John through all females, then they obviously descend from his wife though all females too which means they are a mitochondrial DNA candidate for her.

ymt wiki relationship.png

click to enlarge

Clicking on autosomal testers may reveal someone appropriately descended from the ancestor in question.

You can then click on any ancestor shown to view their profile, and any DNA tested descendants.

By clicking on name of the descendant whose DNA test you are interested in, you’ll be able to view their profile. Look for the Collaboration section where you can send them a private message that will be delivered by email from WikiTree.

ymt collaborate

Finding Y and Mitochondrial DNA Candidates at GedMatch

One final avenue to find Y and mitochondrial DNA candidates is through GedMatch, It’s probably the least useful option, though, because the major vendors all have some sort of tree function, except for 23andMe, and for some reason, many people have not uploaded GEDCOM files (trees) to GEDmatch.

Therefore, if you can find someone on GedMatch that tested elsewhere perhaps, such as LivingDNA who also provides a base haplogroup, or 23andMe, and they uploaded a GEDCOM file (tree) to GedMatch, you can utilize the GEDmatch “Find common ancestors” automated tree-matching functionality.

gedmatch mrca matches

click to enlarge

GEDmatch produces a list of your matches with common ancestors in their trees, allowing you to select the appropriate ancestor or lineage.

I wrote step-by-step instructions in the article, GEDmatch Introduces Automated Tree Matching.

Additionally, GEDmatch includes the Genetic Affairs AutoCluster tool in their Tier1 subscription offering,

ymt gedmatch.png

Gedmatch users who know their Y and mitochondrial haplogroup can enter that information in their profile and it will be reflected on the autosomal match list.

ymt gedmatch hap

Summary Chart

In summary, each testing vendor has a different focus and unique tools that can be used to search for Y and mitochondrial DNA candidates. Additionally, two other resources, WikiTree and GEDmatch, although not DNA testing vendors, can lead to discovering Y and mtDNA candidates as well.

I’ve created a quick-reference chart.

  Family Tree DNA MyHeritage Ancestry 23andMe Wikitree GEDmatch
Y DNA Test Yes No No No, partial haplogroup provided No test, listed by ancestor No, user entered
mtDNA Test Yes No No No, partial haplogroup provided No test, listed by ancestor No, user entered
DNA Projects Yes No No No Some Some
Strengths other than mentioned categories 20 year worldwide customer base, phased family matching European focus, SmartMatches, wide variety of filters Largest autosomal database Genetic tree beta DNA by ancestor May include users not found elsewhere who tested outside the major companies
Drawbacks No direct triangulation or tree matching No Genetic Affairs AutoTree or AutoPedigree Can’t download matches, no triangulation, clusters, AutoTree, or AutoPedigree No trees, 2000 match limit “One tree” may be incorrect Few trees, no AutoTree or AutoPedigree
Clustering Genetic Affairs Included in advanced tools No, prohibited Genetic Affairs N/A Included in Tier1
Genetic Affairs AutoTree & AutoPedigree Yes No No No, no tree support N/A No
Tree matching between users No, through Genetic Affairs Theories of Family Relativity ThruLines No Not directly MRCA common ancestors in Tier1

Now it’s your turn. Which Y and mitochondrial DNA lines can you find today?

Happy Hunting!

Concepts: Inheritance

Inheritance.

What is it?

How does it work?

I’m not talking about possessions – but about the DNA that you receive from your parents, and their parents.

The reason that genetic genealogy works is because of inheritance. You inherit DNA from your parents in a known and predictable fashion.

Fortunately, we have more than one kind of DNA to use for genealogy.

Types of DNA

Females have 3 types of DNA and males have 4. These different types of DNA are inherited in various ways and serve different genealogical purposes.

Males Females
Y DNA Yes No
Mitochondrial DNA Yes Yes
Autosomal DNA Yes Yes
X Chromosome Yes, their mother’s only Yes, from both parents

Different Inheritance Paths

Different types of DNA are inherited from different ancestors, down different ancestral paths.

Inheritance Paths

The inheritance path for Y DNA is father to son and is inherited by the brother, in this example, from his direct male ancestors shown by the blue arrow. The sister does not have a Y chromosome.

The inheritance path for the red mitochondrial DNA for both the brother and sister is from the direct matrilineal ancestors, only, shown by the red arrow.

Autosomal DNA is inherited from all ancestral lines on both the father’s and mother’s side of your tree, as illustrated by the broken green arrow.

The X chromosome has a slightly different inheritance path, depending on whether you are a male or female.

Let’s take a look at each type of inheritance, how it works, along with when and where it’s useful for genealogy.

Autosomal DNA

Autosomal DNA testing is the most common. It’s the DNA that you inherit from both of your parents through all ancestral lines back in time several generations. Autosomal DNA results in matches at the major testing companies such as FamilyTreeDNA, MyHeritage, Ancestry, and 23andMe where testers view trees or other hints, hoping to determine a common ancestor.

How does autosomal DNA work?

22 autosomes

Every person has two each of 22 chromosomes, shown above, meaning one copy is contributed by your mother and one copy by your father. Paired together, they form the two-sided shape we are familiar with.

For each pair of chromosomes, you receive one from your father, shown with a blue arrow under chromosome 1, and one from your mother, shown in red. In you, these are randomly combined, so you can’t readily tell which piece comes from which parent. Therein lies the challenge for genealogy.

This inheritance pattern is the same for all chromosomes, except for the 23rd pair of chromosomes, at bottom right, which determined the sex of the child.

The 23rd chromosome pair is inherited differently for males and females. One copy is the Y chromosome, shown in blue, and one copy is the X, shown in red. If you receive a Y chromosome from your father, you’re a male. If you receive an X from your father, you’re a female.

Autosomal Inheritance

First, let’s talk about how chromosomes 1-22 are inherited, omitting chromosome 23, beginning with grandparents.

Inheritance son daughter

Every person inherits precisely half of each of their parents’ autosomal DNA. For example, you will receive one copy of your mother’s chromosome 1. Your mother’s chromosome 1 is a combination of her mother’s and father’s chromosome 1. Therefore, you’ll receive ABOUT 25% of each of your grandparents’ chromosome 1.

Inheritance son daughter difference

In reality, you will probably receive a different amount of your grandparent’s DNA, not exactly 25%, because your mother or father will probably contribute slightly more (or less) of the DNA of one of their parents than the other to their offspring.

Which pieces of DNA you inherit from your parents is random, and we don’t know how the human body selects which portions are and are not inherited, other than we know that large pieces are inherited together.

Therefore, the son and daughter won’t inherit the exact same segments of the grandparents’ DNA. They will likely share some of the same segments, but not all the same segments.

Inheritance maternal autosomalYou’ll notice that each parent carries more of each color DNA than they pass on to their own children, so different children receive different pieces of their parents’ DNA, and varying percentages of their grandparents’ DNA.

I wrote about a 4 Generation Inheritance Study, here.

Perspective

Keep in mind that you will only inherit half of the DNA that each of your parents carries.

Looking at a chromosome browser, you match your parents on all of YOUR chromosomes.

Inheritance parental autosomal

For example, this is me compared to my father. I match my father on either his mother’s side, or his father’s side, on every single location on MY chromosomes. But I don’t match ALL of my father’s DNA, because I only received half of what he has.

From your parents’ perspective, you only have half of their DNA.

Let’s look at an illustration.

Inheritance mom dad

Here is an example of one of your father’s pairs of chromosomes 1-22. It doesn’t matter which chromosome, the concepts are the same.

He inherited the blue chromosome from his father and the pink chromosome from his mother.

Your father contributed half of his DNA to you, but that half is comprised of part of his father’s chromosome, and part of his mother’s chromosome, randomly selected in chunks referred to as segments.

Inheritance mom dad segments

Your father’s chromosomes are shown in the upper portion of the graphic, and your chromosome that you inherited from you father is shown below.

On your copy of your father’s chromosome, I’ve darkened the dark blue and dark pink segments that you inherited from him. You did not receive the light blue and light pink segments. Those segments of DNA are lost to your line, but one of your siblings might have inherited some of those pieces.

Inheritance mom dad both segments

Now, I’ve added the DNA that you inherited from your Mom into the mixture. You can see that you inherited the dark green from your Mom’s father and the dark peach from your Mom’s mother.

Inheritance grandparents dna

These colored segments reflect the DNA that you inherited from your 4 grandparents on this chromosome.

I often see questions from people wondering how they match someone from their mother’s side and someone else from their father’s side – on the same segment.

Understanding that you have a copy of the same chromosome from your mother and one from your father clearly shows how this happens.

Inheritance match 1 2

You carry a chromosome from each parent, so you will match different people on the same segment. One match is to the chromosome copy from Mom, and one match is to Dad’s DNA.

Inheritance 4 gen

Here is the full 4 generation inheritance showing Match 1 matching a segment from your Dad’s father and Match 2 matching a segment from your Mom’s father.

Your Parents Will Have More Matches Than You Do

From your parents’ perspective, you will only match (roughly) half of the DNA with other people that they will match. On your Dad’s side, on segment 1, you won’t match anyone pink because you didn’t inherit your paternal grandmother’s copy of segment 1, nor did you inherit your maternal grandmother’s segment 1 either. However, your parents will each have matches on those segments of DNA that you didn’t inherit from them.

From your perspective, one or the other of your parents will match ALL of the people you match – just like we see in Match 1 and Match 2.

Matching you plus either of your parents, on the same segment, is exactly how we determine whether a match is valid, meaning identical by descent, or invalid, meaning identical by chance. I wrote about that in the article, Concepts: Identical by…Descent, State, Population and Chance.

Inheritance on chromosomes 1-22 works in this fashion. So does the X chromosome, fundamentally, but the X chromosome has a unique inheritance pattern.

X Chromosome

The X chromosome is inherited differently for males as compared to females. This is because the 23rd pair of chromosomes determines a child’s sex.

If the child is a female, the child inherits an X from both parents. Inheritance works the same way as chromosomes 1-22, conceptually, but the inheritance path on her father’s side is different.

If the child is a male, the father contributes a Y chromosome, but no X, so the only X chromosome a male has is his mother’s X chromosome.

Males inherit X chromosomes differently than females, so a valid X match can only descend from certain ancestors on your tree.

inheritance x fan

This is my fan chart showing the X chromosome inheritance path, generated by using Charting Companion. My father’s paternal side of his chart is entirely blank – because he only received his X chromosome from his mother.

You’ll notice that the X chromosome can only descend from any male though his mother – the effect being a sort of checkerboard inheritance pattern. Only the pink and blue people potentially contributed all or portions of X chromosomes to me.

This can actually be very useful for genealogy, because several potential ancestors are immediately eliminated. I cannot have any X chromosome segment from the white boxes with no color.

The X Chromsome in Action

Here’s an X example of how inheritance works.

Inheritance X

The son inherits his entire X chromosome from his mother. She may give him all of her father’s or mother’s X, or parts of both. It’s not uncommon to find an entire X chromosome inherited. The son inherits no X from his father, because he inherits the Y chromosome instead.

Inheritance X daughter

The daughter inherits her father’s X chromosome, which is the identical X chromosome that her father inherited from his mother. The father doesn’t have any other X to contribute to his daughter, so like her father, she inherits no portion of an X chromosome from her paternal grandfather.

The daughter also received segments of her mother’s X that her mother inherited maternally and paternally. As with the son, the daughter can receive an entire X chromosome from either her maternal grandmother or maternal grandfather.

This next illustration ONLY pertains to chromosome 23, the X and Y chromosomes.

Inheritance x y

You can see in this combined graphic that the Y is only inherited by sons from one direct line, and the father’s X is only inherited by his daughter.

X chromosome results are included with autosomal results at both Family Tree DNA and 23andMe, but are not provided at MyHeritage. Ancestry, unfortunately, does not provide segment information of any kind, for the X or chromosomes 1-22. You can, however, transfer the DNA files to Family Tree DNA where you can view your X matches.

Note that X matches need to be larger than regular autosomal matches to be equally as useful due to lower SNP density. I use 10-15 cM as a minimum threshold for consideration, equivalent to about 7 cM for autosomal matches. In other words, roughly double the rule of thumb for segment size matching validity.

Autosomal Education

My blog is full of autosomal educational articles and is fully keyword searchable, but here are two introductory articles that include information from the four major vendors:

When to Purchase Autosomal DNA Tests

Literally, anytime you want to work on genealogy to connect with cousins, prove ancestors or break through brick walls.

  • Purchase tests for yourself and your siblings if both parents aren’t living
  • Purchase tests for both parents
  • Purchase tests for all grandparents
  • Purchase tests for siblings of your parents or your grandparents – they have DNA your parents (and you) didn’t inherit
  • Test all older generation family members
  • If the family member is deceased, test their offspring
  • Purchase tests for estimates of your ethnicity or ancestral origins

Y DNA

Y DNA is only inherited by males from males. The Y chromosome is what makes a male, male. Men inherit the Y chromosome intact from their father, with no contribution from the mother or any female, which is why men’s Y DNA matches that of their father and is not diluted in each generation.

Inheritance y mtdna

If there are no adoptions in the line, known or otherwise, the Y DNA will match men from the same Y DNA line with only small differences for many generations. Eventually, small changes known as mutations accrue. After many accumulated mutations taking several hundred years, men no longer match on special markers called Short Tandem Repeats (STR). STR markers generally match within the past 500-800 years, but further back in time, they accrue too many mutations to be considered a genealogical-era match.

Family Tree DNA sells this test in 67 and 111 marker panels, along with a product called the Big Y-700.

The Big Y-700 is the best-of-class of Y DNA tests and includes at least 700 STR markers along with SNPs which are also useful genealogically plus reach further back in time to create a more complete picture.

The Big Y-700 test scans the entire useful portion of the Y chromosome, about 15 million base pairs, as compared to 67 or 111 STR locations.

67 and 111 Marker Panel Customers Receive:

  • STR marker matches
  • Haplogroup estimate
  • Ancestral Origins
  • Matches Map showing locations of the earliest known ancestors of matches
  • Haplogroup Origins
  • Migration Maps
  • STR marker results
  • Haplotree and SNPs
  • SNP map

Y, mitochondrial and autosomal DNA customers all receive options for Advanced Matching.

Big Y-700 customers receive, in addition to the above:

  • All of the SNP markers in the known phylotree shown publicly, here
  • A refined, definitive haplogroup
  • Their place on the Block Tree, along with their matches
  • New or unknown private SNPs that might lead to a new haplogroup, or genetic clan, assignment
  • 700+ STR markers
  • Matching on both the STR markers and SNP markers, separately

Y DNA Education

I wrote several articles about understanding and using Y DNA:

When to Purchase Y DNA Tests

The Y DNA test is for males who wish to learn more about their paternal line and match against other men to determine or verify their genealogical lineage.

Women cannot test directly, but they can purchase the Y DNA test for men such as fathers, brothers, and uncles.

If you are purchasing for someone else, I recommend purchasing the Big Y-700 initially.

Why purchase the Big Y-700, when you can purchase a lower level test for less money? Because if you ever want to upgrade, and you likely will, you have to contact the tester and obtain their permission to upgrade their test. They may be ill, disinterested, or deceased, and you may not be able to upgrade their test at that time, so strike while the iron is hot.

The Big Y-700 provides testers, by far, the most Y DNA data to work (and fish) with.

Mitochondrial DNA

Inheritance mito

Mitochondrial DNA is passed from mothers to both sexes of their children, but only females pass it on.

In your tree, you and your siblings all inherit your mother’s mitochondrial DNA. She inherited it from her mother, and your grandmother from her mother, and so forth.

Mitochondrial DNA testers at FamilyTreeDNA receive:

  • A definitive haplogroup, thought of as a genetic clan
  • Matching
  • Matches Map showing locations of the earliest know ancestors of matches
  • Personalized mtDNA Journey video
  • Mutations
  • Haplogroup origins
  • Ancestral origins
  • Migration maps
  • Advanced matching

Of course, Y, mitochondrial and autosomal DNA testers can join various projects.

Mitochondrial DNA Education

I created a Mitochondrial DNA page with a comprehensive list of educational articles and resources.

When to Purchase Mitochondrial DNA Tests

Mitochondrial DNA can be valuable in terms of matching as well as breaking down brick walls for women ancestors with no surnames. You can also use targeted testing to prove, or disprove, relationship theories.

Furthermore, your mitochondrial DNA haplogroup, like Y DNA haplogroups, provides information about where your ancestors came from by identifying the part of the world where they have the most matches.

You’ll want to purchase the mtFull sequence test provided by Family Tree DNA. Earlier tests, such as the mtPlus, can be upgraded. The full sequence test tests all 16,569 locations on the mitochondria and provides testers with the highest level matching as well as their most refined haplogroup.

The full sequence test is only sold by Family Tree DNA and provides matching along with various tools. You’ll also be contributing to science by building the mitochondrial haplotree of womankind through the Million Mito Project.

Combined Resources for Genealogists

You may need to reach out to family members to obtain Y and mitochondrial DNA for your various genealogical lines.

For example, the daughter in the tree below, a genealogist, can personally take an autosomal test along with a mitochondrial test for her matrilineal line, but she cannot test for Y DNA, nor can she obtain her paternal grandmother’s mitochondrial DNA directly by testing herself.

Hearts represent mitochondrial DNA, and stars, Y DNA.

Inheritance combined

However, our genealogist’s brother, father or grandfather can test for her father’s (blue star) Y DNA.

Her father or any of his siblings can test for her paternal grandmother’s (hot pink heart) mitochondrial DNA, which provides information not available from any other tester in this tree, except for the paternal grandmother herself.

Our genealogist’s paternal grandfather, and his siblings, can test for his mother’s (yellow heart) mitochondrial DNA.

Our genealogist’s maternal grandfather can test for his (green star) Y DNA and (red heart) mitochondrial DNA.

And of course, it goes without saying that every single generation upstream of the daughter, our genealogist, should all take autosomal DNA tests.

So, with several candidates, who can and should test for what?

Person Y DNA Mitochondrial Autosomal
Daughter No Y – can’t test Yes, her pink mother’s Yes – Test
Son Yes – blue Y Yes, his pink mother’s Yes – Test
Father Yes – blue Y Yes – his magenta mother’s Yes – Test
Paternal Grandfather Yes – blue Y – Best to Test Yes, his yellow mother’s – Test Yes – Test
Mother No Y – can’t test Yes, her pink mother’s Yes – Test
Maternal Grandmother No Y – can’t test Yes, her pink mother’s – Best to Test Yes – Test
Maternal Grandfather Yes – green Y – Test Yes, his red mother’s – Test Yes – Test

The best person/people to test for each of the various lines and types of DNA is shown bolded above…assuming that all people are living. Of course, if they aren’t, then test anyone else in the tree who carries that particular DNA – and don’t forget to consider aunts and uncles, or their children, as candidates.

If one person takes the Y and/or mitochondrial DNA test to represent a specific line, you don’t need another person to take the same test for that line. The only possible exception would be to confirm a specific Y DNA result matches a lineage as expected.

Looking at our three-generation example, you’ll be able to obtain a total of two Y DNA lines, three mitochondrial DNA lines, and 8 autosomal results, helping you to understand and piece together your family line.

You might ask, given that the parents and grandparents have all autosomally tested in this example, if our genealogist really needs to test her brother, and the answer is probably not – at least not today.

However, in cases like this, I do test the sibling, simply because I can learn and it may encourage their interest or preserve their DNA for their children who might someday be interested. We also don’t know what kind of advances the future holds.

If the parents aren’t both available, then you’ll want to test as many of your (and their) siblings as possible to attempt to recover as much of the parents’ DNA, (and matches) as possible.

Your family members’ DNA is just as valuable to your research as your own.

Increase Your Odds

Don’t let any of your inherited DNA go unused.

You can increase your odds of having autosomal matches by making sure you are in all 4 major vendor databases.

Both FamilyTreeDNA and MyHeritage accept transfers from 23andMe and Ancestry, who don’t accept transfers. Transferring and matching is free, and their unlock fees, $19 at FamilyTreeDNA, and $29 at MyHeritage, respectively, to unlock their advanced tools are both less expensive than retesting.

You’ll find easy-to-follow step-by-step transfer instructions to and from the vendors in the article DNA File Upload-Download and Transfer Instructions to and from DNA Testing Companies.

Genetic Affairs: AutoPedigree Combines AutoTree with WATO to Identify Your Potential Tree Locations

July 2020 Update: Please note that Ancestry issues a cease-and-desist order against Genetic Affairs, and this tool no longer works at Ancestry. The great news is that it still works at the other vendors, and you can ask Ancestry matches to transfer, which is free.

If you’re an adoptee or searching for an unknown parent or ancestor, AutoPedigree is just what you’ve been waiting for.

By now, we’re all familiar with Genetic Affairs who launched in 2018 with their signature autocluster tool. AutoCluster groups your matches into clusters by who your matches match with each other, in addition to you.

browser autocluster

A year later, in December 2019, Genetic Affairs introduced AutoTree, automated tree reconstruction based on your matches trees at Ancestry and Family Finder at Family Tree DNA, even if you don’t have a tree.

Now, Genetic Affairs has introduced AutoPedigree, a combination of the AutoTree reconstruction technology combined with WATO, What Are the Odds, as seen here at DNAPainter. WATO is a statistical probability technique developed by the DNAGeek that allows users to review possible positions in a tree for where they best fit.

Here’s the progressive functionality of how the three Genetic Affairs tools, combined, function:

  • AutoCluster groups people based on if they match you and each other
  • AutoTree finds common ancestors for trees from each cluster
  • Next, AutoTree finds the trees of all matches combined, including from trees of your DNA matches not in clusters
  • AutoPedigree checks to see if a common ancestor tree meets the minimum requirement which is (at least) 3 matches of greater to or equal to 30-40 cM. If yes, an AutoPedigree with hypotheses is created based on the common ancestor of the matching people.
  • Combined AutoPedigrees then reviews all AutoTrees and AutoPedigrees that have common ancestors and combine them into larger trees.

Let’s look at examples, beginning with DNAPainter who first implemented a form of WATO.

DNA Painter

Let’s say you’re trying to figure out how you’re related to a group of people who descend from a specific ancestral couple. This is particularly useful for someone seeking unknown parents or other unknown relationships.

DNA tools are always from the perspective of the tester, the person whose kit is being utilized.

At DNAPainter, you manually create the pedigree chart beginning with a common couple and creating branches to all of their descendants that you match.

This example at DNAPainter shows the matches with their cM amounts in yellow boxes.

xAutoPedigree DNAPainter WATO2

The tester doesn’t know where they fit in this pedigree chart, so they add other known lines and create hypothesis placeholder possibilities in light blue.

In other words, if you’re searching for your mother and you were born in 1970, you know that your mother was likely born between 1925 (if she was 45 when she gave birth to you) and 1955 (if she was 15 when she gave birth to you.) Therefore, in the family you create, you’d search for parents who could have given birth to children during those years and create hypothetical children in those tree locations.

The WATO tool then utilizes the combination of expected cMs at that position to create scores for each hypothesis position based on how closely or distantly you match other members of that extended family.

The Shared cM Project, created and recently updated by Blaine Bettinger is used as the foundation for the expected centimorgan (cM) ranges of each relationship. DNAPainter has automated the possible relationships for any given matching cM amount, here.

In the graphic above, you can see that the best hypothesis is #2 with a score of 1, followed by #4 and #5 with scores of 3 each. Hypothesis 1 has a score of 63.8979 and hypothesis 3 has a score of 383.

You’ll need to scroll to the bottom to determine which of the various hypothesis are the more likely.

Autopedigree DNAPainter calculated probability

Using DNAPainter’s WATO implementation requires you to create the pedigree tree to test the hypothesis. The benefit of this is that you can construct the actual pedigree as known based on genealogical research. The down-side, of course, is that you have to do the research to current in each line to be able to create the pedigree accurately, and that’s a long and sometimes difficult manual process.

Genetic Affairs and WATO

Genetic Affairs takes a different approach to WATO. Genetic Affairs removes the need for hand entry by scanning your matches at Ancestry and Family Tree DNA, automatically creating pedigrees based on your matches’ trees. In addition, Genetic Affairs automatically creates multiple hypotheses. You may need to utilize both approaches, meaning Genetic Affairs and DNAPainter, depending on who has tested, tree completeness at the vendors, and other factors.

The great news is that you can import the Genetic Affairs reconstructed trees into DNAPainter’s WATO tool instead of creating the pedigrees from scratch. Of course, Genetic Affairs can only use the trees someone has entered. You, on the other hand, can create a more complete tree at DNAPainter.

Combining the two tools leverages the unique and best features of both.

Genetic Affairs AutoPedigree Options

Recently, Genetic Affairs released AutoPedigree, their new tool that utilizes the reconstructed AutoTrees+WATO to place the tester in the most likely region or locations in the reconstructed tree.

Let’s take a look at an example. I’m using my own kit to see what kind of results and hypotheses exist for where I fit in the tree reconstructed from my matches and their trees.

If you actually do have a tree, the AutoTree portion will simply be counted as an equal tree to everyone else’s trees, but AutoPedigree will ignore your tree, creating hypotheses as if it doesn’t exist. That’s great for adoptees who may have hypothetical trees in progress, because that tree is disregarded.

First, sign on to your account at Genetic Affairs and select the AutoPedigree option for either Ancestry or Family Tree DNA which reconstructs trees and generates hypotheses automatically. For AutoPedigree construction, you cannot combine the results from Ancestry and FamilyTreeDNA like you can when reconstructing trees alone. You’ll need to do an AutoPedigree run for each vendor. The good news is that while Ancestry has more testers and matches, FamilyTreeDNA has many testers stretching back 20 years or so in the past who passed away before testing became available at Ancestry. Often, their testers reach back a generation or two further. You can easily transfer Ancestry (and other) results to Family Tree DNA for free to obtain more matches – step-by-step instructions here.

At Genetic Affairs, you should also consider including half-relations, especially if you are dealing with an unknown parent situation. Selecting half-relationships generates very large trees, so you might want to do the first run without, then a second run with half relationships selected.

AutoPedigree options

Results

I ran the program and opened the resulting email with the zip file. Saving that file automatically unzips for me, displaying the following 5 files and folders.

Autopedigree cluster

Clicking on the AutoCluster HTML link reveals the now-familiar clusters, shown below.

Autopedigree clusters

I have a total of 26 clusters, only partially shown above. My first peach cluster and my 9th blue cluster are huge.

Autopedigree 26 clusters

That’s great news because it means that I have a lot to work with.

autopedigree folder

Next, you’ll want to click to open your AutoPedigree folder.

For each cluster, you’ll have a corresponding AutoPedigree file if an AutoPedigree can be generated from the trees of the people in that cluster.

My first cluster is simply too large to show successfully in blog format, so I’m selecting a smaller cluster, #21, shown below with the red arrow, with only 6 members. Why so small, you ask? In part, because I want to illustrate the fact that you really don’t need a lot of matches for the AutoPedigree tool to be useful.

Autopedigree multiple clusters

Note also that this entire group of clusters (blue through brown) has members in more than one cluster, indicated by the grey cells that mean someone is a member of at least 2 clusters. That tells me that I need to include the information from those clusters too in my analysis. Fortunately, Genetic Affairs realizes that and provides a combined AutoPedigree tool for that as well, which we will cover later in the article. Just note for now that the blue through brown clusters seem to be related to cluster 21.

Let’s look at cluster 21.

autopedigree cluster 21

In the AutoPedigree folder, you’ll see cluster files when there are trees available to create pedigrees for individual clusters. If you’re lucky, you’ll find 2 files for some clusters.

autopedigree ancestors

At the top of each cluster AutoPedigree file, Genetic Affairs shows you the home couple of the descendant group shown in the matches and their corresponding trees.

Autopedigree WATO chart

Image 1 – click to enlarge

I don’t expect you to be able to read everything in the above pedigree chart, just note the matches and arrows.

You can see three of my cousins who match, labeled with “Ancestry.” You also see branches that generate a viable hypothesis. When generating AutoPedigrees, Genetic Affairs truncates any branches that cannot result in a viable hypothesis for placing the tester in a viable location on the tree, so you may not see all matches.

Autopedigree hyp 1

Image 2 – click to enlarge

On the top branch, you’ll see hyp-1-child1 which is the first hypothesis, with the first child. Their child is hyp-2- child2, and their child is hyp-3-child3. The tester (me, in this case) cannot be the persons shown with red flags, called badges, based on how I match other people and other tree information such as birth and death dates.

Think of a stoplight, red=no, green are your best bets and the rest are yellow, meaning maybe. AutoPedigree makes no decisions, only shows you options, and calculated mathematically how probable each location is to be correct.

Remember, these “children,” meaning hypothesis 1-child 1 may or may not have actually existed. These relationships are hypothetical showing you that IF these people existed, where the tester could appear on the tree.

We know that I don’t fit on the branch above hypothesis 1, because I only match the descendant of Adam Lentz at 44.2 cM which is statistically too low for me to also inhabit that branch.

I’ve included half relationships, so we see hyp-7-child1-half too, which is a half-sibling.

The rankings for hypotheses 1, 2, and 7 all have red badges, meaning not possible, so they have a score of 0. Hypothesis 3 and 8 are possible, with a ranking of 16, respectively.

autopedigree my location

Image 3 – click to enlarge

Looking now at the next segment of the tree, you see that based on how I match my Deatsman and Hartman cousins, I can potentially fit in any portion of the tree with green badges (in the red boxes) or yellow badges.

You can also see where I actually fit in the tree. HOWEVER, that placement is from AutoTree, the tree reconstruction portion, based on the fact that I have a tree (or someone has a tree with me in it). My own tree is ignored for hypothesis generation for the AutoPedigree hypothesis generation portion.

Had my first cousins once removed through my grandfather John Ferverda’s brother, Roscoe, tested AND HAD A TREE, there would have been no question where I fit based on how I match them.

autopedigree cousins

As it turns out they did test, but provided no tree meaning that Genetic Affairs had no tree to work with.

Remember that I mentioned that my first cluster was huge. Many more matches mean that Genetic Affairs has more to work with. From that cluster, here’s an example of a hypothesis being accurate.

autopedigree correct

Image 4 – click to enlarge

You can see the hypothetical line beneath my own line, with hypothesis 104, 105, 106, 107, 108. The AutoTree portion of my tree is shown above, with my father and grandparents and my name in the green block. The AutoPedigree portion ignores my own tree, therefore generating the hypothesis that’s where I could fit with a rank of 2. And yes, that’s exactly where I fit in the tree.

In this case, there were some hypotheses ranked at 1, but they were incorrect, so be sure to evaluate all good (green) options, then yellow, in that order.

Genetic Affairs cannot work with 23andMe results for AutoPedigree because 23andMe doesn’t provide or support trees on their site. AutoClusters are integrated at MyHeritage, but not the AutoTree or AutoPedigree functions, and they cannot be run separately.

That leaves Family Tree DNA and Ancestry.

Combined AutoPedigree

After evaluating each of the AutoPedigrees generated for each cluster for which an AutoPedigree can be generated, click on the various cluster combined autopedigrees.

autopedigree combined

You can see that for cluster 1, I have 7 separate AutoPedigrees based on common ancestors that were different. I have 3 AutoPedigrees also for cluster 9, and 2 AutoPedigrees for 15, 21, and 24.

I have no AutoPedigrees for clusters 2, 3, 5, 6, 7, 8, 14, 17, 18, and 22.

Moving to the combined clusters, the numbers of which are NOT correlated to the clusters themselves, Genetic Affairs has searched trees and combined ancestors in various clusters together when common ancestors were found.

Autopedigree multiple clusters

Remember that I asked you to note that the above blue through brown clusters seem to have commonality between the clusters based on grey cell matches who are found in multiple groups? In fact, these people do share common ancestors, with a large combined AutoPedigree being generated from those multiple clusters.

I know you can’t read the tree in the image that follows. I’m only including it so you’ll see the scale of that portion of my tree that can be reconstructed from my matches with hypotheses of where I fit.

autopedigree huge

Image 5 – click to enlarge

These larger combined pedigrees are very useful to tie the clusters together and understand how you match numerous people who descend from the same larger ancestral group, further back in time.

Integration with DNAPainter

autopedigree wato file

Each AutoPedigree file and combined cluster AutoPedigree file in the AutoPedigree folder is provided in WATO format, allowing you to import them into DNAPainter’s WATO tool.

autopedigree dnapainter import

You can manually flesh out the trees based on actual genealogy in WATO at DNAPainter, manually add matches from GEDmatch, 23andMe or MyHeritage or matches from vendors where your matches trees may not exist but you know how your match connects to you.

Your AutoTree Ancestors

But wait, there’s more.

autopedigree ancestors folder

If you click on the Ancestors folder, you’ll see 5 options for tree generations 3-7.

autopedigree ancestor generations

My three-generation auto-generated reconstructed tree looks like this:

autopedigree my tree

Selecting the 5th generation level displays Jacob Lentz and Frederica Ruhle, the couple shown in the AutoCluster 21 and AutoPedigree examples earlier. The color-coding indicates the source of the ancestors in that position.

Autopedigree expanded tree

click to enlarge

You will also note that Genetic Affairs indicates how many matches I have that share this common ancestor along with which clusters to view for matches relevant to specific ancestors. How cool is this?!!

Remember that you can also import the genetic match information for each AutoTree cluster found at Family Tree DNA into DNAPainter to paint those matches on your chromosomes using DNAPainter’s Cluster Auto Painter.

If you run AutoCluster for matches at 23andMe, MyHeritage, or FamilyTreeDNA, all vendors who provide segment information, you can also import that cluster segment information into DNAPainter for chromosome painting.

However, from that list of vendors, you can only generate AutoTrees and AutoPedigrees at Family Tree DNA. Given this, it’s in your best interest for your matches to test at or upload their DNA (plus tree) to Family Tree DNA who supports trees AND provides segment information, both, and where you can run AutoTree and AutoPedigree.

Have you painted your clusters or generated AutoTrees? If you’re an adoptee or looking for an unknown parent or grandparent, the new AutoPedigree function is exactly what you need.

Documentation

Genetic Affairs provides complete instructions for AutoPedigree in this newsletter, along with a user manual here, and the Facebook Genetic Affairs User Group can be found here.

Concepts: Chromosome Browser – What Is It, How Do I Use It, and Why Do I Care?

The goal of genetic genealogy is to utilize DNA matches to verify known ancestors and identify unknown ancestors.

A chromosome browser is a tool that allows testers to visualize and compare their DNA on each chromosome with that of their genetic matches. How to utilize and interpret that information becomes a little more tricky.

I’ve had requests for one article with all the information in one place about chromosome browsers:

  • What they are
  • How and when to use them
  • Why you’d want to

I’ve included a feature comparison chart and educational resource list at the end.

I would suggest just reading through this article the first time, then following along with your own DNA results after you understand the basic landscape. Using your own results is the best way to learn anything.

What Does a Chromosome Browser Look Like?

Here’s an example of a match to my DNA at FamilyTreeDNA viewed on their chromosome browser.

browser example.png

On my first 16 chromosomes, shown above, my 1C1R (first cousin once removed,) Cheryl, matches me where the chromosomes are painted blue. My chromosome is represented by the grey background, and her matching portion by the blue overlay.

Cheryl matches me on some portion of all chromosomes except 2, 6, and 13, where we don’t match at all.

You can select any one person, like Cheryl, from your match list to view on a chromosome browser to see where they match you on your chromosomes, or you can choose multiple matches, as shown below.

browser multiple example.png

I selected my 7 closest matches that are not my immediate family, meaning not my parents or children. I’m the background grey chromosome, and each person’s match is painted on top of “my chromosome” in the location where they match me. You see 7 images of my grey chromosome 1, for example, because each of the 7 people being compared to me are shown stacked below one another.

Everyplace that Cheryl matches me is shown on the top image of each chromosome, and our matching segment is shown in blue. The same for the second red copy of the chromosome, representing Don’s match to me. Each person I’ve selected to match against is shown by their own respective color.

You’ll note that in some cases, two people match me in the same location. Those are the essential hints we are looking for. We’ll be discussing how to unravel, interpret, and use matches in the rest of this article.

browser MyHeritage example.png

The chromosome browser at MyHeritage looks quite similar. However, I have a different “top 7” matches because each vendor has people who test on their platform who don’t test or transfer elsewhere.

Each vendor that supports chromosome browsers (FamilyTreeDNA, MyHeritage, 23andMe, and GedMatch) provides their own implementation, of course, but the fundamentals of chromosome browsers, how they work and what they are telling us is universal.

Why Do I Need a Chromosome Browser?

“But,” you might say, “I don’t need to compare my DNA with my matches because the vendors already tell me that I match someone, which confirms that we are related and share a common ancestor.”

Well, not exactly. It’s not quite that straightforward.

Let’s take a look at:

  • How and why people match
  • What matches do and don’t tell you
  • Both with and without a chromosome browser

In part, whether you utilize a chromosome browser or not depends on which of the following you seek:

  • A broad-brush general answer; yes or no, I match someone, but either I don’t know how are related, or have to assume why. There’s that assume word again.
  • To actually confirm and prove your ancestry, getting every ounce of value out of your DNA test.

Not everyone’s goals are the same. Fortunately, we have an entire toolbox with a wide range of tools. Different tools are better suited for different tasks.

People seeking unknown parents should read the article, Identifying Unknown Parents and Individuals Using DNA Matching because the methodology for identifying unknown parents is somewhat different than working with genealogy. This article focuses on genealogy, although the foundation genetic principles are the same.

If you’re just opening your DNA results for the first time, the article, First Steps When Your DNA Results are Ready – Sticking Your Toe in the Genealogy Water would be a great place to start.

Before we discuss chromosome browsers further, we need to talk about DNA inheritance.

Your Parents

Every person has 2 copies of each of their 22 chromosomes – one copy contributed by their mother and one copy contributed by their father. A child receives exactly half of the autosomal DNA of each parent. The DNA of each parent combines somewhat randomly so that you receive one chromosome’s worth of DNA from each of your parents, which is half of each parent’s total.

On each chromosome, you receive some portion of the DNA that each parent received from their ancestors, but not exactly half of the DNA from each individual ancestor. In other words, it’s not sliced precisely in half, but served up in chunks called segments.

Sometimes you receive an entire segment of an ancestor’s DNA, sometimes none, and sometimes a portion that isn’t equal to half of your parent’s segment.

browser inheritance.png

This means that you don’t receive exactly half of the DNA of each of your grandparents, which would be 25% each. You might receive more like 22% from one maternal grandparent and 28% from the other maternal grandparent for a total of 50% of the DNA you inherit from your parents. The other 50% of your DNA comes from the other parent, of course. I wrote about that here.

There’s one tiny confounding detail. The DNA of your Mom and Dad is scrambled in you, meaning that the lab can’t discern scientifically which side is which and can’t tell which pieces of DNA came from Mom and which from Dad. Think of a genetic blender.

Our job, using genetic genealogy, is to figure out which side of our family people who match us descend from – which leads us to our common ancestor(s).

Parallel Roads

For the purposes of this discussion, you’ll need to understand that the two copies you receive of each chromosome, one from each parent, have the exact same “addresses.” Think of these as parallel streets or roads with identical addresses on each road.

browser street.png

In the example above, you can see Dad’s blue chromosome and Mom’s red chromosome as compared to me. Of course, children and parents match on the full length of each chromosome.

I’ve divided this chromosome into 6 blocks, for purposes of illustration, plus the centromere where we generally find no addresses used for genetic genealogy.

In the 500 block, we see that the address of 510 Main (red bar) could occur on either Dad’s chromosome, or Mom’s. With only an address and nothing more, you have no way to know whether your match with someone at 510 Main is on Mom’s or Dad’s side, because both streets have exactly the same addresses.

Therefore, if two people match you, at the same address on that chromosome, like 510 Main Street, they could be:

  • Both maternal matches, meaning both descended from your mother’s ancestors, and those two people will also match each other
  • Both paternal matches, meaning both descended from your father’s ancestors, and those two people will also match each other
  • One maternal and one paternal match, and those two people will not match each other

Well then, how do we know which side of the family a match descends from, and how do we know if we share a common ancestor?

Good question!

Identical by Descent

If you and another person match on a reasonably sized DNA segment, generally about 7 cM or above, your match is probably “identical by descent,” meaning not “identical by chance.” In this case, then yes, a match does confirm that you share a common ancestor.

Identical by descent (IBD) means you inherited the piece of DNA from a common ancestor, inherited through the relevant parent.

Identical by chance (IBC) means that your mom’s and dad’s DNA just happens to have been inherited by you randomly in a way that creates a sequence of DNA that matches that other person. I wrote about both IBD and IBC here.

MMB stats by cM 2

This chart, courtesy of statistician Philip Gammon, from the article Introducing the Match-Maker-Breaker Tool for Parental Phasing shows the percentage of time we expect matches of specific segment sizes to be valid, or identical by descent.

Identical by Chance

How does this work?

How is a match NOT identical by descent, meaning that it is identical by chance and therefore not a “real” or valid match, a situation also known as a false positive?

browser inheritance grid.png

The answer involves how DNA is inherited.

You receive a chromosome with a piece of DNA at every address from both parents. Of course, this means you have two pieces of DNA at each address. Therefore people will match you on either piece of DNA. People from your Dad’s side will match you on the pieces you inherited from him, and people from your Mom’s side will match you on the pieces you inherited from her.

However, both of those matches have the same address on their parallel streets as shown in the illustration, above. Your matches from your mom’s side will have all As, and those from your dad’s side will have all Ts.

The problem is that you have no way to know which pieces you inherited from Mom and from Dad – at least not without additional information.

You can see that for 10 contiguous locations (addresses), which create an example “segment” of your DNA, you inherited all As from your Mom and all Ts from your Dad. In order to match you, someone would either need to have an A or a T in one of their two inherited locations, because you have an A and a T, both. If the other person has a C or a G, there’s no match.

Your match inherited a specific sequence from their mother and father, just like you did. As you can see, even though they do match you because they have either an A or a T in all 10 locations – the As and Ts did not all descend from either their mother or father. Their random inheritance of Ts and As just happens to match you.

If your match’s parents have tested, you won’t match either of their parents nor will they match either of your parents, which tells you immediately that this match is by chance (IBC) and not by descent (IBD), meaning this segment did not come from a common ancestor. It’s identical by chance and, therefore, a false positive.

If We Match Someone Else In Common, Doesn’t That Prove Identical by Descent?

Nope, but I sure wish it did!

The vendors show you who else you and your match both match in common, which provides a SUGGESTION as to your common ancestor – assuming you know which common ancestor any of these people share with you.

browser icw.png

However, shared matches are absolutely NOT a guarantee that you, your match, and your common matches all share the same ancestor, unless you’re close family. Your shared match could match you or your match through different ancestors – or could be identical by chance.

How can we be more confident of what matching is actually telling us?

How can we sort this out?

Uncertainties and Remedies

Here’s are 9 things you DON’T know, based on matching alone, along with tips and techniques to learn more.

  1. If your match to Person A is below about 20cM, you’ll need to verify that it’s a legitimate IBD match (not IBC). You can achieve this by determining if Person A also matches one of your parents and if you match one of Person A’s parents, if parents have tested.

Not enough parents have tested? An alternative method is by determining if you and Person A both match known descendants of the candidate ancestors ON THE SAME SEGMENT. This is where the chromosome browser enters the picture.

In other words, at least three people who are confirmed to descend from your presumptive common ancestor, preferably through at least two different children, must match on a significant portion of the same segment.

Why is that? Because every segment has its own unique genealogical history. Each segment can and often does lead to different ancestors as you move further back in time.

In this example, I’m viewing Buster, David, and E., three cousins descended from the same ancestral couple, compared to me on my chromosome browser. I’m the background grey, and they show in color. You can see that all three of them match me on at least some significant portion of the same segment of chromosome 15.

browser 3 cousins.png

If those people also match each other, that’s called triangulation. Triangulation confirms descent from a common ancestral source.

In this case, I already know that these people are related on my paternal side. The fact that they all match my father’s DNA and are therefore all automatically assigned to my paternal matching tab at Family Tree DNA confirms my paper-trail genealogy.

I wrote detailed steps for triangulation at Family Tree DNA, here. In a nutshell, matching on the same segment to people who are bucketed to the same parent is an automated method of triangulation.

Of course, not everyone has the luxury of having their parents tested, so testing other family members, finding common segments, and assigning people to their proper location in your tree facilitates confirmation of your genealogy (and automating triangulation.)

The ONLY way you can determine if people match you on the same segment, and match each other, is having segment information available to you and utilizing a chromosome browser.

browser MyHeritage triangulation.png

In the example above, the MyHeritage triangulation tool brackets matches that match you (the background grey) and who are all triangulated, meaning they all also match each other. In this case, the portion where all three people match me AND each other is bracketed. I wrote about triangulation at MyHeritage here.

  1. If you match several people who descend from the same ancestor, John Doe, for example, on paper, you CANNOT presume that your match to all of those people is due to a segment of DNA descended from John Doe or his wife. You may not match any of those people BECAUSE OF or through segments inherited from John Doe or his wife. You need segment information and a chromosome browser to view the location of those matches.

Assuming these are legitimate IBD matches, you may share another common line, known or unknown, with some or all of those matches.

It’s easy to assume that because you match and share matches in common with other people who believe they are descended from that same ancestor:

  • That you’re all matching because of that ancestor.
  • Even on the same segments.

Neither of those presumptions can be made without additional information.

Trust me, you’ll get yourself in a heap o’ trouble if you assume. Been there, done that. T-shirt was ugly.

Let’s look at how this works.

browser venn.png

Here’s a Venn diagram showing me, in the middle, surrounded by three of my matches:

  • Match 1 – Periwinkle, descends from Lazarus Estes and Elizabeth Vannoy
  • Match 2 – Teal, descends from Joseph Bolton and Margaret Claxton
  • Match 3 – Mustard, descends from John Y. Estes and Rutha Dodson

Utilizing a chromosome browser, autocluster software, and other tools, we can determine if those matches also match each other on a common segment, which means they triangulate and confirm common ancestral descent.

Of course, those people could match each other due to a different ancestor, not necessarily the one I share with them nor the ancestors I think we match through.

If they/we do all match because they descend from a common ancestor, they can still match each other on different segments that don’t match me.

I’m in the center. All three people match me, and they also match each other, shown in the overlap intersections.

Note that the intersection between the periwinkle (Match 1) and teal (Match 2) people, who match each other, is due to the wives of the children of two of my ancestors. In other words, their match to each other has absolutely nothing to do with their match to me. This was an “aha’ moment for me when I first realized this was a possibility and happens far more than I ever suspected.

The intersection of the periwinkle (Match 1) and mustard (Match 3) matches is due to the Dodson line, but on a different segment than they both share with me. If they had matched each other and me on the same segment, we would be all triangulated, but we aren’t.

The source of the teal (Match 2) to mustard (Match 3) is unknown, but then again, Match 3’s tree is relatively incomplete.

Let’s take a look at autocluster software which assists greatly with automating the process of determining who matches each other, in addition to who matches you.

  1. Clustering technology, meaning the Leeds method as automated by Genetic Affairs and DNAGedcom help, but don’t, by themselves, resolve the quandary of HOW people match you and each other.

People in a colored cluster all match you and each other – but not necessarily on the same segment, AND, they can match each other because they are related through different ancestors not related to your ancestor. The benefit of autocluster software is that this process is automated. However, not all of your matches will qualify to be placed in clusters.

browser autocluster.png

My mustard cluster above includes the three people shown in the chromosome browser examples – and 12 more matches that can be now be researched because we know that they are all part of a group of people who all match me, and several of whom match each other too.

My matches may not match each other for a variety of reasons, including:

  • They are too far removed in time/generations and didn’t inherit any common ancestral DNA.
  • This cluster is comprised of some people matching me on different (perhaps intermarried) lines.
  • Some may be IBC matches.

Darker grey boxes indicate that those people should be in both clusters, meaning the red and mustard clusters, because they match people in two clusters. That’s another hint. Because of the grid nature of clusters, one person cannot be associated with more than 2 clusters, maximum. Therefore, people like first cousins who are closely related to the tester and could potentially be in many clusters are not as useful in clusters as they are when utilizing other tools.

  1. Clusters and chromosome browsers are much less complex than pedigree charts, especially when dealing with many people. I charted out the relationships of the three example matches from the Venn diagram. You can see that this gets messy quickly, and it’s much more challenging to visualize and understand than either the chromosome browser or autoclusters.

Having said that, the ultimate GOAL is to identify how each person is related to you and place them in their proper place in your tree. This, cumulatively with your matches, is what identifies and confirms ancestors – the overarching purpose of genealogy and genetic genealogy.

Let’s take a look at this particular colorized pedigree chart.

Browser pedigree.png

click to enlarge

The pedigree chart above shows the genetic relationship between me and the three matches shown in the Venn diagram.

Four descendants of 2 ancestral couples are shown, above; Joseph Bolton and Margaret Claxton, and John Y. Estes and Rutha Dodson. DNA tells me that all 3 people match me and also match each other.

The color of the square (above) is the color of DNA that represents the DNA segment that I received and match with these particular testers. This chart is NOT illustrating how much DNA is passed in each generation – we already know that every child inherits half of the DNA of each parent. This chart shows match/inheritance coloring for ONE MATCHING SEGMENT with each match, ONLY.

Let’s look at Joseph Bolton (blue) and Margaret Claxton (pink). I descend through their daughter, Ollie Bolton, who married William George Estes, my grandfather. The DNA segment that I share with blue Match 2 (bottom left) is a segment that I inherited from Joseph Bolton (blue). I also carry inherited DNA from Margaret Claxton too, but that’s not the segment that I share with Match 2, which is why the path from Joseph Bolton to me, in this case, is blue – and why Match 2 is blue. (Just so you are aware, I know this segment descends from Joseph Bolton, because I also match descendants of Joseph’s father on this segment – but that generation/mtach is not shown on this pedigree chart.)

If I were comparing to someone else who I match through Margaret Claxton, I would color the DNA from Margaret Claxton to me pink in that illustration. You don’t have to DO this with your pedigree chart, so don’t worry. I created this example to help you understand.

The colored dots shown on the squares indicate that various ancestors and living people do indeed carry DNA from specific ancestors, even though that’s not the segment that matches a particular person. In other words, the daughter, Ollie, of Joseph Bolton and Margaret Claxton carries 50% pink DNA, represented by the pink dot on blue Ollie Bolton, married to purple William George Estes.

Ollie Bolton and William George Estes had my father, who I’ve shown as half purple (Estes) and half blue (Bolton) because I share Bolton DNA with Match 2, and Estes DNA with Match 1. Obviously, everyone receives half of each parent’s DNA, but in this case, I’m showing the path DNA descended for a specific segment shared with a particular match.

I’ve represented myself with the 5 colors of DNA that I carry from these particular ancestors shown on the pedigree chart. I assuredly will match other people with DNA that we’ve both inherited from these ancestors. I may match these same matches shown with DNA that we both inherited from other ancestors – for example, I might match Match 2 on a different segment that we both inherited from Margaret Claxton. Match 2 is my second cousin, so it’s quite likely that we do indeed share multiple segments of DNA.

Looking at Match 3, who knows very little about their genealogy, I can tell, based on other matches, that we share Dodson DNA inherited through Rutha Dodson.

I need to check every person in my cluster, and that I share DNA with on these same segment addresses to see if they match on my paternal side and if they match each other.

  1. At Family Tree DNA, I will be able to garner more information about whether or not my matches match each other by using the Matrix tool as well as by utilizing Phased Family Matching.

At Family Tree DNA, I determined that these people all match in common with me and Match 1 by using the “In Common With” tool. You can read more about how to use “In Common With” matching, here.

browser paternal.png

Family Matching phases the matches, assigning or bucketed them maternally or paternally (blue and red icons above), indicating, when possible, if these matches occur on the same side of your family. I wrote about the concept of phasing, here, and Phased Family Matching here and here.

Please note that there is no longer a limit on how distantly related a match can be in order to be utilized in Phased Family Matching, so long as it’s over the phase-matching threshold and connected correctly in your tree.

browser family tree dna link tree.png

Bottom line, if you can figure out how you’re related to someone, just add them into your tree by creating a profile card and link their DNA match to them by simply dragging and dropping, as illustrated above.

Linking your matches allows Family Matching to maternally or paternally assign other matches that match both you and your tree-linked matches.

If your matches match you on the same segment on the same parental side, that’s segment triangulation, assuming the matches are IBD. Phased Family Matching does this automatically for you, where possible, based on who you have linked in your tree.

For matches that aren’t automatically bucketed, there’s another tool, the Matrix.

browser matrix.png

In situations where your matches aren’t “bucketed” either maternally or paternally, the Matrix tool allows you to select matches to determine whether your matches also match each other. It’s another way of clustering where you can select specific people to compare. Note that because they also match each other (blue square) does NOT mean it’s on the same segment(s) where they match you. Remember our Venn diagram.

browser matrix grid.png

  1. Just because you and your matches all match each other doesn’t mean that they are matching each other because of the same ancestor. In other words, your matches may match each other due to another or unknown ancestor. In our pedigree example, you can see that the three matches match each other in various ways.
browser pedigree match.png

click to enlarge

  • Match 1 and Match 2 match each other because they are related through the green Jones family, who is not related to me.
  • Match 2 and Match 3 don’t know why they match. They both match me, but not on the same segment they share with each other.
  • Match 1 and Match 3 match through the mustard Dodson line, but not on the same segment that matches me. If we all did match on the same segment, we would be triangulated, but we wouldn’t know why Match 3 was in this triangulation group.
  1. Looking at a downloaded segment file of your matches, available at all testing vendors who support segment information and a chromosome browser, you can’t determine without additional information whether your matches also match each other.

browser chr 15.png

Here’s a group of people, above, that we’ve been working with on chromosome 15.

My entire match-list shows many more matches on that segment of chromosome 15. Below are just a few.

browser chr 15 all

Looking at seven of these people in the chromosome browser, we can see visually that they all overlap on part of a segment on chromosome 15. It’s a lot easier to see the amount of overlap using a browser as opposed to the list. But you can only view 7 at a time in the browser, so the combination of both tools is quite useful. The downloaded spreadsheet shows you who to select to view for any particular segment.

browser chr 15 compare.png

The critical thing to remember is that some matches will be from tyour mother’s side and some from your father’s side.

Without additional information and advanced tools, there’s no way to tell the difference – unless they are bucketed using Phased Family Matching at Family Tree DNA or bracketed with a triangulation bracket at MyHeritage.

At MyHeritage, this assumes you know the shared ancestor of at least one person in the triangulation group which effectively assigns the match to the maternal or paternal side.

Looking at known relatives on either side, and seeing who they also match, is how to determine whether these people match paternally or maternally. In this example below, the blue people are bucketed paternally through Phased Family Matching, the pink maternally, and the white rows aren’t bucketed and therefore require additional evaluation.

browser chr 15 maternal paternal.png

Additional research shows that Jonathan is a maternal match, but Robert and Adam are identical by chance because they don’t match either of my parents on this segment. They might be valid matches on other segments, but not this one.

browser chr 15 compare maternal paternal.png

  1. Utilizing relatives who have tested is a huge benefit, and why we suggest that everyone test their closest upstream relatives (meaning not children or grandchildren.) Testing all siblings is recommended if both parents aren’t available to test, because every child received different parts of their parents’ DNA, so they will match different relatives.

After deleting segments under 7 cM, I combine the segment match download files of multiple family members (who agree to allow me to aggregate their matches into one file for analysis) so that I can create a master match file for a particular family group. Sorting by match name, I can identify people that several of my cousins’ match.

browser 4 groups.png

This example is from a spreadsheet where I’ve combined the results of about 10 collaborating cousins to determine if we can break through a collective brick wall. Sorted by match name, this table shows the first 4 common matches that appear on multiple cousin’s match lists. Remember that how these people match may have nothing to do with our brick wall – or it might.

Note that while the 4 matches, AB, AG, ag, and A. Wayne, appear in different cousins’ match lists, only one shares a common segment of DNA: AB triangulates with Buster and Iona. This is precisely WHY you need segment information, and a chromosome browser, to visualize these matches, and to confirm that they do share a common DNA segment descended from a specific ancestor.

These same people will probably appear in autocluster groups together as well. It’s worth noting, as illustrated in the download example, that it’s much more typical for “in common with” matches to match on different segments than on the same segment. 

  1. Keep in mind that you will match both your mother and father on every single chromosome for the entire length of each chromosome.

browser parent matching.png

Here’s my kit matching with my father, in blue, and mother, in red on chromosomes 1 and 2.

Given that I match both of my parents on the full chromosome, inheriting one copy of my chromosome from each parent, it’s impossible to tell by adding any person at random to the chromosome browser whether they match me maternally or paternally. Furthermore, many people aren’t fortunate enough to have parents available for testing.

To overcome that obstacle, you can compare to known or close relatives. In fact, your close relatives are genetic genealogy gold and serve as your match anchor. A match that matches you and your close relatives can be assigned either maternally or paternally. I wrote about that here.

browser parent plus buster.png

You can see that my cousin Buster matches me on chromosome 15, as do both of my parents, of course. At this point, I can’t tell from this information alone whether Buster matches on my mother’s or father’s side.

I can tell you that indeed, Buster does match my father on this same segment, but what if I don’t have the benefit of my father’s DNA test?

Genealogy tells me that Buster matches me on my paternal side, through Lazarus Estes and Elizabeth Vannoy. Given that Buster is a relatively close family member, I already know how Buster and I are related and that our DNA matches. That knowledge will help me identify and place other relatives in my tree who match us both on the same segment of DNA.

To trigger Phased Family Matching, I placed Buster in the proper place in my tree at Family Tree DNA and linked his DNA. His Y DNA also matches the Estes males, so no adoptions or misattributed parental events have occurred in the direct Estes patrilineal line.

browser family tree dna tree.png

I can confirm this relationship by checking to see if Buster matches known relatives on my father’s side of the family, including my father using the “in common with” tool.

Buster matches my father as well as several other known family members on that side of the family on the same segments of DNA.

browser paternal bucket.png

Note that I have a total of 397 matches in common with Buster, 140 of which have been paternally bucketed, 4 of which are both (my children and grandchildren), and 7 of which are maternal.

Those maternal matches represent an issue. It’s possible that those people are either identical by chance or that we share both a maternal and paternal ancestor. All 7 are relatively low matches, with longest blocks from 9 to 14 cM.

Clearly, with a total of 397 shared matches with Buster, not everyone that I match in common with Buster is assigned to a bucket. In fact, 246 are not. I will need to take a look at this group of people and evaluate them individually, their genealogy, clusters, the matrix, and through the chromosome browser to confirm individual matching segments.

There is no single perfect tool.

Every Segment Tells a Unique History

I need to check each of the 14 segments that I match with Buster because each segment has its own inheritance path and may well track back to different ancestors.

browser buster segments.png

It’s also possible that we have unknown common ancestors due to either adoptions, NPEs, or incorrect genealogy, not in the direct Estes patrilineal line, but someplace in our trees.

browser buster paint.png

The best way to investigate the history and genesis of each segment is by painting matching segments at DNAPainter. My matching segments with Buster are shown painted at DNAPainter, above. I wrote about DNAPainter, here.

browser overlap.png

By expanding each segment to show overlapping segments with other matches that I’ve painted and viewing who we match, we can visually see which ancestors that segment descends from and through.

browser dnapainter walk back.png

These roughly 30 individuals all descend from either Lazarus Estes and Elizabeth Vannoy (grey), Elizabeth’s parents (dark blue), or her grandparents (burgundy) on chromosome 15.

As more people match me (and Buster) on this segment, on my father’s side, perhaps we’ll push this segment back further in time to more distant ancestors. Eventually, we may well be able to break through our end-of-line brick wall using these same segments by looking for common upstream ancestors in our matches’ trees.

Arsenal of Tools

This combined arsenal of tools is incredibly exciting, but they all depend on having segment information available and understanding how to use and interpret segment and chromosome browser match information.

One of mine and Buster’s common segments tracks back to end-of-line James Moore, born about 1720, probably in Virginia, and another to Charles Hickerson born about 1724. It’s rewarding and exciting to be able to confirm these DNA segments to specific ancestors. These discoveries may lead to breaking through those brick walls eventually as more people match who share common ancestors with each other that aren’t in my tree.

This is exactly why we need and utilize segment information in a chromosome browser.

We can infer common ancestors from matches, but we can’t confirm segment descent without specific segment information and a chromosome browser. The best we can do, otherwise, is to presume that a preponderance of evidence and numerous matches equates to confirmation. True or not, we can’t push further back in time without knowing who else matches us on those same segments, and the identity of their common ancestors.

The more evidence we can amass for each ancestor and ancestral couple, the better, including:

  • Matches
  • Shared “In Common With” Matches, available at all vendors.
  • Phased Family Matching at Family Tree DNA assigns matches to maternal or paternal sides based on shared, linked DNA from known relatives.
  • The Matrix, a Family Tree DNA tool to determine if matches also match each other. Tester can select who to compare.
  • ThruLines from Ancestry is based on a DNA match and shared ancestors in trees, but no specific segment information or chromosome browser. I wrote about ThruLines here and here.
  • Theories of Family Relativity, aka TOFR, at MyHeritage, based on shared DNA matches, shared ancestors in trees and trees constructed between matches from various genealogical records and sources. MyHeritage includes a chromosome browser and triangulation tool. I wrote about TOFR here and here.
  • Triangulation available through Phased Family Matching at Family Tree DNA and the integrated triangulation tool at MyHeritage. Triangulation between only 3 people at a time is available at 23andMe, although 23andMe does not support trees. See triangulation article links in the Resource Articles section below.
  • AutoClusters at MyHeritage (cluster functionality included), at Genetic Affairs (autoclusters plus tree reconstruction) and at DNAGedcom (including triangulation).
  • Genealogical information. Please upload your trees to every vendor site.
  • Y DNA and mitochondrial DNA confirmation, when available, through Family Tree DNA. I wrote about the 4 Kinds of DNA for Genetic Genealogy, here and the importance of Y DNA confirmation here, and how not having that information can trip you up.
  • Compiled segment information at DNAPainter allows you to combine segment information from various vendors, paint your maternal and paternal chromosomes, and visually walk segments back in time. Article with DNAPainter instructions is found here.

Ability to Know if Matches Match Each Other (also see autoclusters) Yes, through Matrix tool or if match on common bucketed segment through Family Matching Yes, through triangulation tool if all match on common segment No Yes, can compare any person to any other person on your match list Yes, through comparison tool selections
Autoclusters Can select up to 10 people for Matrix grid, also available for entire match list through Genetic Affairs and DNAGedcom which work well Genetic Affairs clustering included free, DNAGedcom has difficulty due to timeouts No, but Genetic Affairs and DNAGedcom work well No, but Genetic Affairs and DNAGedcom work well Yes, Genetic Affairs included in Tier 1 for selected kits, DNAGedcom is in beta
Trees Can upload or create tree. Linking you and relatives who match to tree triggers Phased Family Matching Can upload or create tree. Link yourself and kits you manage assists Theories of Family Relativity Can upload or create tree. Link your DNA to your tree to generate ThruLines. Recent new feature allows linking of DNA matches to tree. No tree support but can provide a link to a tree elsewhere Upload your tree so your matches can view
Matching and Automated Tree Construction of DNA Matches who Share Common Ancestors with You Genetic Affairs for matches with common ancestors with you Not available Genetic Affairs for matches with common ancestors with you No tree support Not available
Matching and Automated Tree Construction for DNA Matches with Common Ancestors with Each Other, But Not With You Genetic Affairs for matches with common ancestors with each other, but not with you Not available Genetic Affairs for matches with common ancestors with each other, but not with you No tree support Not available
DNAPainter Segment Compilation and Painting Yes, bucketed Family Match file can be uploaded which benefits tester immensely. Will be able to paint ethnicity segments soon. Yes No segment info available, encourage your matches to upload elsewhere Yes, and can paint ethnicity segments from 23andMe, Yes, but only for individually copied matches or highest 1000.
Y DNA and Mitochondrial Matching Yes, both, includes multiple tools, deep testing and detailed matching No No No, base haplogroup only, no matching No, haplogroup only if field manually completed by tester when uploading autosomal DNA file

Transfer Your DNA

Transferring your DNA results to each vendor who supports segment information and accepts transfers is not only important, it’s also a great way to extend your testing collar. Every vendor has strengths along with people who are found there and in no other database.

Ancestry does not provide segment information nor a chromosome browser, nor accept uploads, but you have several options to transfer your DNA file for free to other vendors who offer tools.

23andMe does provide a chromosome browser but does not accept uploads. You can download your DNA file and transfer free to other vendors.

I wrote detailed upload/download and transfer instructions for each vendor, here.

Two vendors and one third party support transfers into their systems. The transfers include matching. Basic tools are free, but all vendors charge a minimal fee for unlocking advanced tools, which is significantly less expensive than retesting:

Third-party tools that work with your DNA results include:

All vendors provide different tools and have unique strengths. Be sure that your DNA is working as hard as possible for you by fishing in every pond and utilizing third party tools to their highest potential.

Resource Articles

Explanations and step by step explanations of what you will see and what to do, when you open your DNA results for the first time.

Original article about chromosomes having 2 sides and how they affect genetic genealogy.

This article explains what triangulation is for autosomal DNA.

Why some matches may not be valid, and how to tell the difference.

This article explains the difference between a match group, meaning a group of people who match you, and triangulation, where that group also matches each other. The concepts are sound, but this article relies heavily on spreadsheets, before autocluster tools were available.

Parental phasing means assigning segment matches to either your paternal or maternal side.

Updated, introductory article about triangulation, providing the foundation for a series of articles about how to utilize triangulation at each vendor (FamilyTreeDNA, MyHeritage, 23andMe, GEDmatch, DNAPainter) that supports triangulation.

These articles step you through triangulation at each vendor.

DNAPainter facilitates painting maternally and paternally phased, bucketed matches from FamilyTreeDNA, a method of triangulation.

Compiled articles with instructions and ideas for using DNAPainter.

Autoclustering tool instructions.

How and why The Leeds Method works.

Step by step instructions for when and how to use FamilyTreeDNA’s chromosome browser.

Close family members are the key to verifying matches and identifying common ancestors.

This article details how much DNA specific relationships between people can expect to share.
