Wringing Every Drop Out of Mitochondrial DNA – FREE Webinar

Please join me on Wednesday, April 27th at 2 PM EDT for Wringing Every Drop out of Mitochondrial DNA at Legacy Family Tree Webinars.

https://familytreewebinars.com/webinar/wringing-every-drop-out-of-mitochondrial-dna/

  • In this webinar, we will learn step-by-step how to utilize mitochondrial DNA testing at FamilyTreeDNA to get the most out of your results.
  • We begin with mitochondrial education, then we’ll look at little-known methods to obtain information, even if your match doesn’t have a tree.
  • We’ll talk about using resources such as Geni, WikiTree Ancestry’s ThruLines, MyHeritage’s Theories of Family Relativity, and others to break down mitochondrial brick walls.
  • We’ll discuss FamilyTreeDNA projects and show an example of using mitochondrial DNA in conjunction with autosomal for a slam-dunk.
  • Last, we’ll have an update about The Million Mito Project and why it’s important to you.

You can register at this link and enjoy the webinar for free.

East Coast Genetic Genealogy Conference – Registration is Open!

Did you know that the East Coast Genetic Genealogy Conference (ECGGC, affectionally known as “eggs”) is taking place on April 23 and 24? If you haven’t heard of this conference before, that’s because this is its inaugural year.

ECCGC was initially scheduled to be held in Maryland, in person, but the uptick in Covid over the winter forced a go, no-go decision at a time when a virtual live-streamed conference assured everyone’s safety.

I’m excited about speaking, especially my opening keynote, “DNA – Past, Present and Future.” I’ll reflect a little, talk about the current state-of-affairs and then discuss what the future may hold. Just think what we will be able to do in the next decade, or two, based on how far we’ve come in the past 22 years.

Of course, the very best aspect of this two-day conference is that it’s entirely focused on genetic genealogy which makes it the PERFECT venue for Mitochondrial DNA Academy. More about that in a minute.

Speakers

The 23 speakers read like a who’s who in the genetic genealogy space. You can read about each speaker, here.

Schedule and Sessions

If you look at the sessions and schedule, here, you’ll notice that there are 37 sessions offered over two days. Simple math tells you that you can’t possibly attend all of those in two days – even if you stayed up all night.

The great news is that for all attendees, the sessions will be recorded and available to watch after the actual conference itself is over.

Mitochondrial DNA Academy – You’re Invited

I want to personally invite you to attend Mitochondrial DNA Academy, presented by Dr. Miguel Vilar, Dr. Paul Maier, and me.

Mitochondrial DNA is an incredibly misunderstood tool for genealogy. It seems that anytime someone mentions mitochondrial DNA on social media and asks if they should purchase a test, a cacophony of “buy an autosomal test instead” resounds, without even asking the purpose of the test in question, or what the person hopes to learn.

Understanding mitochondrial DNA itself, how it’s used, what to expect, and how to utilize the results for genealogy is key to making an informed decision.

For those of us who do work extensively with mitochondrial DNA, there’s still much to learn. Attending both Paul Maier and Miguel Vilar’s portions of the Academy is guaranteed to provide even experienced genetic genealogists with fascinating, detailed information. There’s something for everyone and a unique learning opportunity.

If you want to understand the science behind mitochondrial DNA, how it works, different types of mutations, extra and missing mutations, frequency, haplogroup formation, migration, populations, phylogenetic trees as well as how to tie all of this up in a bundle to use successfully for genetic genealogy – Mitochondrial DNA Academy is for you.

You may have noticed that the three of us constitute three-quarters of the Million Mito Project team, so you just might get an update on that project as well!

Register for the Conference

You can register, here, for $150 which provides access to both conference days and all of the recorded sessions after.

Sponsors

I want to say a big thank you to the ECGGC sponsors, DNAGedcom, Borland Genetics, MyHeritage, FamilyTreeDNA and mitoYDNA.org whose generous sponsorships offset the cost of the conference for attendees.

See you at the conference!

Hurry: Relatives at RootsTech Ends March 25 – Search for Y & Mitochondrial DNA Cousins While You Can

Relatives for RootsTech is still available through March 25th, even though RootsTech, the event, is over for this year. (Obviously, the video sessions are still available.)

Relatives at RootsTech provides participants with the opportunity to see cousins, organized in different ways, including by ancestor, with a path for both of you drawn back to your common ancestors.

Be sure to fully utilize the Relatives at RootsTech connections to easily find cousins who descend appropriately to be testing candidates for Y DNA and mitochondrial DNA for your ancestors. I’ve included step-by-step instructions in this article along with a few hints I’ve discovered.

Just navigate to RootsTech, here, and scroll down to the relatives at RootsTech button.

Click that button, then on “view relatives” and voila, here you are.

FamilySearch has made this easy by displaying your relatives by ancestor, at least for several generations back in time. You can see how many of your cousins descend from any particular ancestor.

While my closest ancestors are showing few cousins, more distant ancestors further down my relatives list, (and further back in my tree,) have hundreds.

It’s Easy Peasy

Eventually, every single line brick walls. Y DNA and mitochondrial DNA are the ONLY types of DNA you can use that doesn’t divide in every generation and remains as reliable 10 or more generations ago as today. Y DNA and mitochondrial DNA are laser lights shining back through time. We need them for every single ancestral line to push beyond that brick wall, whenever and wherever we hit it.

I’ve spent time in the past few days fishing for cousins and messaging people who are good candidates to represent lines that I don’t have represented in my DNA pedigree chart.

In my own desktop software, I enter my ancestor’s haplogroup as a middle name. The * means I’ve written a 52 Ancestors series article about this person. (I don’t do this in public trees, just my own.)

I can see at a glance which ancestors don’t have haplogroups, which means I need to find cousins who descend appropriately to have inherited either the Y DNA or the mitochondrial DNA of that ancestor.

The blue boxes above represent the Y DNA inheritance path, and the red, mitochondrial inheritance. You can read more about Y and mitochondrial DNA inheritance paths, here.

Neither Y nor mitochondrial DNA are admixed with the DNA of the other parent, so it’s a rich source of information that never divides during meiosis. This gives us the ability to see far back in time without dilution.

Focus

I created a small spreadsheet so I wouldn’t lose track of whose DNA I’m looking for and the message I sent to various cousins.

By focusing only on ancestral lines I specifically need, I’ve eliminated a lot of busy work. Initially, I was going to record every cousin, but there are too many for me to be able to complete that task. Now I’m focused on:

  • Lines where I have very few matches. These may represent closer cousins I haven’t yet met, or people in the Netherlands who are now participating. I found a new Dutch cousin. Hopefully they will reply to my message.
  • Y DNA lines
  • Mitochondrial DNA lines

Timesaving Hint

When searching in this manner, find your most distant ancestor on the relatives list in that line. For example, I only have two cousins on my Lazarus Estes list, but as I look at ancestors on up that Estes line, I have several more by the time you get to Moses Estes, 4 generations earlier. My two cousins who descend from Lazarus will ALSO be on the Moses Estes list – as will all the rest of my cousins who descend from Estes males between Lazarus Estes and Moses Estes.

Moving to the earliest ancestors in a line immediately saves you a heap of time because you don’t need to view your cousins in the closer generations.

Y DNA

Finding appropriate cousins for Y DNA is easy. They will generally carry the surname of the ancestor in question. If I’m searching for a descendant of Andrew McKee (c1766-1814), I’ll just look for McKee surname cousins on my list.

To see how your cousin descends from your common ancestor click on Relationship. A nice dual path is shown to your common ancestors.

I found a female, so I messaged her and ask if she has a father or brother or uncle who would be willing to test to represent the McKee Y DNA line.

In my message, I briefly explain how beneficial this would be for everyone in that line and might well help break down those upstream brick walls. Who were Andrew’s parents?

I don’t know now, but I’d surely know more after a Y DNA test. So would she!

In this next example, my cousin is male, and the last male shown descending from Andrew is Robert Clayton McKee. I “presume” my cousin descends through two upstream males, but sometimes that’s not the case. Either of those two greyed out people could be females. I’m always “gentle” in these messages and say that “It appears that you descend from Andrew through all males. FamilySearch conceals the identity of your closest generations for privacy.”

I ask my cousin to confirm how they descend and ask if they have tested or are interested in DNA testing. I also provide my email address and offer a testing scholarship.

Mitochondrial DNA

Locating mitochondrial DNA testing candidates takes slightly more effort, but can be VERY productive.

Let’s say I’m searching for a mitochondrial DNA candidate for Andrew McKee’s wife.

Notice, I said “wife” and did not mention her name. All we really know, from a deed signature releasing her dower right, is that her first name is Elizabeth. The reason I would be seeking her mitochondrial DNA is to figure out who her parents were.

At FamilySearch, Elizabeth has been assigned a full name, including surname, but there are no sources that provide her surname.

DO NOT DISREGARD THIS RECORD!

My first inclination is to disregard this record because there is no evidence that Barnes is Elizabeth’s surname, at least not that I’ve ever seen. If any reader has actual evidence, please do share.

However, in this case, we are searching for anyone descended from the wife of Andrew McKee, REGARDLESS OF HER NAME. Her name, in this context and for this purpose does not matter.

In other words, if we can find a candidate for Andrew’s wife’s mitochondrial DNA, we may then be able to determine if indeed she does match someone in the Barnes family line.

It’s very easy to skim your matches ancestral line. If you see any blue in their lineage, indicating a male in your cousin’s line, that’s an immediate “no,” so you can just proceed to the next cousin in your list.

Mitochondrial DNA is only passed from women to their children. Men don’t pass it on, so a male in that line is a blocker. Andrew McKee Jones, in this example, inherited his mother’s mitochondrial DNA, but his children inherited the mitochondrial DNA of their mother.

Fortunately, FamilySearch also identifies daughter or son when names are ambiguous.

Scholarships

I always offer a DNA testing scholarship at FamilyTreeDNA for the appropriate Y DNA or mitochondrial test. FamilyTreeDNA also offers their autosomal Family Finder test, of course, and I often include that test in the scholarship.

Other vendors do not offer Y and mitochondrial DNA testing. However, if your cousins have already tested autosomally at Ancestry, 23andMe, or MyHeritage, they can upload their DNA files to FamilyTreeDNA for free after you order their scholarship test. Step-by-step upload instructions can be found, here.

I always check to see if Y DNA and mtDNA testers’ matches are also autosomal matches. That too can provide valuable clues.

March 25th

Don’t wait. The Relatives at RootsTech tool is only available until March 25th. It will take you some time to review the lists, but it’s fun because it’s like mining for buried ancestral gold nuggets. Except it’s not just a game. There is real genealogical gold hiding there, just itching to be discovered.

If you message someone, or click on the contact button, they will be added to your list which remains available after March 25th.

Do you have ancestors whose Y DNA and mitochondrial DNA you need? Your gold-nugget cousin may be waiting for you!

Top Ten RootsTech 2022 DNA Sessions + All DNA Session Links

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The navigation bar is at the top of your page.

New Options

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

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

Session Availability

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

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

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

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

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

Expo Hall

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

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

Speaker’s Bookstore

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

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

Sessions

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

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

Live Sessions Calendar

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

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

Be sure to review each group and make your selections.

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

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

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

Session Search

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

Click to enlarge any image

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

Session Filters

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

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

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

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

You could add language or other filters as well.

Series Filter

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

Doggone Pesky Bugs

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

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

Add to the PlayList

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

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

Using Your PlayList

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

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

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

I heartily recommend putting this session on your PlayList.

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

Innovators Portal

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

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

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

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

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

My Sessions

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

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

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

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

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

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

Thursday, March 3rd – 10 AM EST

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

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

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

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

Thursday, March 3rd – 2 PM EST LIVE

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

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

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

Friday, March 4th – 10 AM LIVE, Series

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

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

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

Friday March 4th – 2 PM LIVE, Series

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

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

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

Your Turn

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

Preserving Items for Future DNA Testing – Teeth, Stamps, Envelopes, Hats, Hair and More

I often receive questions about testing items from deceased people. Is that type of testing available, and is it successful?

The answer is some shade of grey depending on several factors.

So, let’s start with no and work our way up!

NO

Today for the normal air-breathing human, testing items for DNA in a commercial lab for genealogical purposes is not yet feasible. In part, this is due to the labor-intensive extraction costs plus the fact that often, when DNA is able to be retrieved, it’s not of sufficient quality to pass the stringent guidelines of the testing companies.

Compounding that issue is one of consent. How does the testing company actually know the item is from someone deceased AND that you have the legal right to request the specified service?

There are other problems too.

How do you know the stamp was really licked by your ancestor or the intended person and not by the person at the post office, or a family member or neighbor? You don’t.

How do you know the DNA retrieved is actually that of your ancestor or intended person and not contaminant DNA from someone else? You don’t.

And yes, I know there are companies that enter our periphery from time to time that advertise the ability to provide this service. So far, I’ve not seen consistent success which is why these companies don’t stay around long. It’s very expensive, for them and for the consumer, just to try. Regardless of the outcome.

The Technology

The intricate extraction methodology and processing is the same technology used to process forensic samples from crime scenes or to identify unknown deceased people.

Clearly, in some cases, it’s technically possible. However, remember that this type of work requires a special lab, costs in the ballpark of $2000 per sample, or more, and the results often need to be compared in a database environment that accepts partial or degraded results.

My advice – don’t even attempt this now unless you have LOTS of whatever it is from the deceased person and don’t mind sacrificing some of it, along with some big $$, and be prepared to receive no result. I’ve now tried this twice without success.

However, this isn’t the situation with someone recently deceased.

YES

While processing DNA from the recently deceased is not a commercially available service today, it’s sometimes possible.

You need to collect a DNA sample immediately after death using a swab kit. If you’re like me, you always have a DNA kit at home, but you might not be like me or you might not be at home.

You can call FamilyTreeDNA and have them overnight a kit to you or the funeral home, or you can go to the closest pharmacy and purchase an Identigene DNA kit. This brand includes swabs. Ask the mortician to swab the inside of the cheeks of the deceased. (Do NOT send the swabs in the kit to Identigene – you’re only using their swabs in order to send it to FamilyTreeDNA.)

Hopefully, there is no denture adhesive present, as that interferes with DNA processing.

While swabbing is recommended prior to embalming, if embalming has already occurred, ask them to swab anyway. The worst thing that will happen is that it won’t work. It’s worth a try.

I wrote about the process, here.

Clearly, with a swab kit, you’ll need a DNA company that uses swabs to do the processing. That eliminates both Ancestry and 23andMe which use spit kits, leaving as candidates only FamilyTreeDNA and MyHeritage. Fortunately, you can upload DNA files from one to the other.

MAYBE

Some things fall in-between yes and no, meaning taking a swab of a recently deceased person to process at FamilyTreeDNA and attempting to process an artifact.

For example, blood cards or tissue samples fall into this category. In this case, the challenge will be finding a lab that will accept that item.

FamilyTreeDNA may, but you’ll need to contact them in advance as it’s on a case-by-case basis.

Candidate Items

Please keep in mind that all items can be contaminated by handling. To handle, wear sterile gloves and use sterile tweezers. Your goal is to avoid contamination by handling or storage.

We’ll discuss storage and preservation in the next section.

Here’s a list of common candidate items and my comments:

Item Comments
Hair Can be contaminated. May not include the follicle which is your best bet for autosomal DNA. While mitochondrial DNA is most typically extracted from hair, using forensic methods, in some cases, autosomal can be extracted as well.
Envelopes and stamps High probability of contamination. Special processing needs to be utilized due to the adhesive which in some cases is animal-based which means it contains animal DNA.
Teeth Should be in good shape and not have cavities, meaning baby teeth are better candidates than extracted teeth. Normally, adult teeth aren’t extracted without a reason. Don’t throw anything away though.
Hearing aids Hearing aids often contain ear wax and skin cells and make good candidates.
Glasses nose pads The nose pad or metal connecting the nose pad to the glasses frame sometimes harbors skin cells.
Dentures Possible candidates although adhesive interferes with DNA as does soaking denture in cleaning solutions.
Electric razors Excellent candidates since residue held in razors generally contains skin cells. However, be sure your relative is the only person who used the razor. Contact the lab for instructions before extracting the contents.
Blood cards and tissue samples Excellent source but the lab needs to be contacted about whether they accept this type of sample and how to send it safely. Blood and tissue samples may be held by a medical facility if the person was hospitalized, received treatment, or a post-mortem was performed.
Hats, sweaty items, etc. Possible candidates but it depends on the item, its age, and condition. Contact the lab with specifics. With hats, check for embedded hairs which may be a better source than the hat itself.
Used Kleenex type tissue If you’re positive that the tissue was used by the target person, this is a great source of DNA.
Toothbrush Sometimes, but bacteria can be an issue. Doesn’t hurt to save a toothbrush after allowing to dry completely
Fingernail and toenail clippings Clippings are a great source of DNA. Be sure to check clippers, as some have little “catchers” built-in. Also check the drawer where clippers are stored, assuming there is only one individual using those clippers.
Travel bag If your relative traveled from time to time, check the bag in their suitcase that held their personal items. You never know what you might find. Mine holds many DNA-rich items and yours probably does too.

If your relative passed away from something communicable, you need to take that into consideration.

Storage and Preservation Guidelines

While this type of DNA processing service isn’t commercially available as an off-the-shelf service yet today, as technology improves and prices reduce, I feel confident it will be a viable, readily-available service someday. I’ve been saying that for years now, and I just hope someday isn’t too far in the future.

Your challenge is to keep your sample of whatever it is in good condition, so it doesn’t degrade irrecoverably while you are waiting.

  • NEVER store items in plastic including ziplocks or baggies. Plastic prevents air circulation and encourages mold.
  • NEVER use any type of tape or adhesive.
  • DO store each item individually in paper, like an envelope, preferable acid-free paper.
  • If you store an item in fabric, DO wash the fabric first to remove dye, stabilizers and dirt as well as DNA residue from other people. Handle the fabric with sterile gloves after washing.
  • DON’T store the item against wood and not in a cedar chest. Wood contains tannins which are acids that stain and leach into other items.
  • DON’T store the item in the sun, a hot attic or humid basement.
  • DO store the item in a safe, dark location in a temperature-controlled area of your home.
  • DO label the container the item is stored in.

I have several items from my father and grandfather that I’m keeping with the hope of someday being able to utilize them. I have them stored individually in an acid-free envelope, in a small train case, buffered by acid free tissue paper, with nothing else touching the envelope, in my closet.

I’ve also enclosed a note for my daughter, just in case she finds those one day and wonders what they are and why they are packaged in that manner.

Don’t Throw It Away

Let’s say you’ve already done DNA testing on your parent, then they pass away.

As you go through their things, you see hairbrushes and razors and maybe even find a tissue in a nightgown pocket.

You think about how those items would be good for DNA testing and you’re glad you already did that. That means you don’t need to save those things, right? Wrong!

DON’T throw those items away. They’re treasure. There may be new vendors in the future, new companies that process and utilize DNA. There will assuredly be advances in science and new products, and you may wish you had those DNA sources.

I saved my Mom’s hairbrush and Kleenexes from her bathrobe pocket for this exact reason. She lived alone and no one else would have used those items.

Complicating Circumstances

Biological processes accelerate and degrade DNA.

For example, heat.

The heat of modern-day cremations destroys all DNA, even though residual bone fragments are left.

Cold, meaning freezing, would typically preserve DNA, unless a repeated freeze/thaw cycle is involved. In other words, don’t store those teeth in a frost-free refrigerator. I know someone who froze something in an ice cube tray and suffice it to say that a guest received a VERY unexpected surprise one hot summer day. In another instance, a power failure caused everything in a freezer to be thrown away. Freezing is generally not the best choice.

If your ancestor died in a fire, or the home burned but some items were preserved – maybe.

If flooding or water was involved, again, think mold and rapid degradation. Dry those items but without high heat and not in a dryer. If you’re dealing with sewer water, dispose of the items.

The bottom line is this – if there’s enough of an item left to see and identify, other than cremains, there’s enough to preserve, just in case.

Truly, you never know. The best you can do is to begin preservation now and work with what you have.

Staying on the Right Side of the Law

I’m not a lawyer, but I do know that there are required legal procedures to exhume remains for testing. Those laws and procedures vary by location.

Do not try this at home. Contact a lawyer in the jurisdiction where the person you hope to test is buried and be prepared to convince at least five people that your need is pressing and justifiable:

  • The lawyer (bring a large check)
  • Other family members, ALL of whom will likely be required to sign and notarize their agreement
  • A judge who will ultimately decide
  • The coroner or other individual to arrange exhumation and take the sample
  • A lab to process the sample and if it’s not your DNA testing lab, agreement from your DNA lab to allow your sample to be uploaded

You’ve probably figured out why you never see anyone discussing having exhumed their dearly departed for testing. The hoops are many and the process is exorbitantly complex and expensive. Just moving a grave a mile or so down the road when a cemetery was being permanently flooded, without getting a court order or taking a biological sample cost a friend in excess of $20,000 several years ago.

Alternate Strategies

If you’re seeking the Y DNA or mitochondrial DNA of that ancestor, another family member appropriately descended may be able to serve as a proxy. Work your way up the tree to find test candidates and create a DNA Pedigree Chart.

Males inherit their father’s Y chromosome along with their surname. Everyone received their mother’s mitochondrial DNA, but only females pass it on.

Autosomal DNA, at least in part can sometimes be inferred by matching with other people from the same side through family matching, or conversely, not sharing a match with someone that you know is from either your paternal or maternal side on the same segment.

You can read more about how different kinds of DNA is passed to descendants, here.

Summary

Today, testing most artifact items isn’t a viable strategy to retrieve DNA, but there are some notable exceptions. Alternate testing strategies may prove more fruitful

However, taking appropriate measures to preserve these items for future testing is a great strategy. The worst that can happen is that it doesn’t work. You’ll never know if you don’t take those preservation steps today.

The best outcome, of course, is that one day your ancestor’s DNA will be able to assist your genealogy. I can hardly wait!

What is a Heteroplasmy and Why Do I Care?

Most people have never heard of a heteroplasmy – but you might have one.

You Might Have a Heteroplasmy If…

…You have no exact matches at the full sequence mitochondrial DNA level.

A heteroplasmy is one of the first things I think of when someone tells me they have no exact full sequence matches but several that are a genetic distance of 1, meaning one mutation difference.

That phenomenon usually means the tester has a rare mutation that no one else has, at least no one who has tested their mitochondrial DNA (yet) – and that mutation just might be a heteroplasmy.

Heteroplasmies are generally (but not always) quite recent mutations. Actually, heteroplasmies are mutations caught in the act of mutating – kind of like an insect in genetic amber – frozen in time in your generation.

By Anders L. Damgaard – http://www.amber-inclusions.dk – Baltic-amber-beetle CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=16792582

Let’s say you might have a heteroplasmy. Or maybe you want to see if you do. Even if YOU don’t have a heteroplasmy, other people’s heteroplasmies can and will affect matching.

Here’s everything you ever wanted to know about heteroplasmies but didn’t know to ask😊

Heteroplasmies are Fascinating

A heteroplasmy is actually quite interesting because it’s a genetic mutation in progress.

This means you have two versions of a DNA sequence showing in your mitochondrial DNA at a specific location.

Said another way, at a specific genetic location, you show both of two separate nucleotides. Amounts detected of a second nucleotide greater than 20% are considered a heteroplasmy. Amounts below 20% are ignored. Generally, within a few generations, the mutation will resolve in one direction or the other – although some heteroplasmies persist for several generations and can sometimes define family branches.

If you’d like to read more about mitochondrial DNA, I wrote a series of step-by-step articles and combined them into one resource page, here.

Show Me!

You can easily check to see if you have a heteroplasmy by signing on to your FamilyTreeDNA account. Hopefully, you’ve taken the full sequence test.

Today, new testers, thankfully, can only purchase full sequence tests, so HVR1 results don’t present quite the same challenges when combined with heteroplasmies as they used to. We’ll talk about that in a minute.

If you have only taken the HVR1 or HVR1+HVR2 “Plus” test, as opposed to the Full Sequence, you can upgrade by signing on here and clicking on the “Full” button on the Maternal Ancestry section of your personal page.

These buttons will be pink if you’ve taken that test already, and grey if you need to upgrade. If you have an account at FamilyTreeDNA, you can add a mitochondrial DNA test to that same account by clicking on “Add Ons and Upgrades” at the top of your personal page. You can order a test if you’re a new customer, here.

How Do I Know if I Have a Heteroplasmy?

Your mitochondrial DNA has a total of 16,569 locations that you can think of as addresses. If your DNA at those locations is normal, meaning no mutations, they won’t be listed in your results.

Mutations are shown in your mitochondrial DNA results by a different letter at the end of the location.

For example, here are my mutations for my HVR1 region. Each of these locations in the HVR1 region has a mutation.

For locations that are shown in your results, meaning those where you have a mutation, you’ll see, in order:

  • A letter, either T, A, C or G
  • The location number
  • A different letter, typically another one of T, A, C or G, but sometimes a small d

For the first mutation, C16069T, the location address is 16069, the normal value is C, the mutation that occurred is T.

Heteroplasmies are shown in your mitochondrial DNA results by letters other than T, A, C, G or d at the end of the location.

I don’t have any heteroplasmies, so I’m switching to the results of a cousin who has a heteroplasmic mutation at location T16362Y to use as an example. The trailing Y means they have a heteroplasmy at location 16362.

But first, what do those letters mean?

The Letters

The letters stand for the nucleotide bases that comprise DNA, as follows:

  • T – Thymine
  • A – Adenine
  • C – Cytosine
  • G – Guanine
  • d – a deletion has occurred. There is no nucleotide at this location.

For location T16362Y, the first letter, T, is the “normal” value found at this location. If a mutation has occurred, the second letter is the mutated value. Normally, this is one of the other nucleotides, A, C or G.

Any other letter after the location has a specific meaning; in this case, Y means that both a C and a T were found, per the chart below.

Note – if you have a small letter t, a, c or g, it’s not a heteroplasmy, and I wrote about small letters and what they mean in the article, Mitochondrial DNA Part 2: What Do Those Numbers Mean?

Check Your Results

On your FamilyTreeDNA personal page in the mtDNA section, click on the Mutations tab.

If you’ve taken the full sequence test, you’ll see Extra Mutations. You’re looking for any mutation that ends in any letter other than T, A, C, G or d.

If you haven’t taken the full sequence test, you don’t have “Extra” mutations listed, but you can still view your mutations for the HVR1 and HVR2 regions.

Look for any value that has any letter other than T, A, C, G or lower case d at the end of the location.

The Y tells us that this location is a heteroplasmy.

Heteroplasmy Matching

Ok, let’s look at a heteroplasmy mutation at location 16326. A heteroplasmy can occur at any mitochondrial location. I’ve selected this location because it occurs in the HVR1 region of the mitochondrial DNA, so even people who haven’t tested at the full sequence level will see results for this location. Plus, the location at which the heteroplasmy occurs affects matching in different ways.

Using the example of T16362Y, the Y tells us that both nucleotides C and T were found. This location should match against anyone carrying the following values in the same location:

  • Y (letter indicating a C/T heteroplasmy)
  • T (standard or normal value)
  • C (mutated value)

However, currently at Family Tree DNA, the heteroplasmy only counts as a match to anyone with a Y, the specific heteroplasmy indicator, and the “normal” value of T, but not the mutated value of C.

This table shows how heteroplasmies are counted at FamilyTreeDNA. For heteroplasmy T16362Y, based on the value your potential match has at this location, you either will or will not be considered a match at that location.

Scenario Other Person’s Value Your Result – T16362Y
1 T16362Y – heteroplasmy indicator Match to you at this location
2 T16362T – normal value, not a mutation Match to you at this location
3 T16362C – mutated value Not counted as match to you at this location
  • If your match has a value of Y, the heteroplasmic C/T value, they are counted as a match to you, so no problem.
  • If your match has a value of T, the normal value, this location won’t be shown on their mutation list at all. They WILL be counted as a match to you so there’s no issue.
  • If your match has a value of C, the mutated value, in my opinion they should also be counted as a match to you, but they aren’t today. The logic, I believe, was that the most likely value is the standard or normal value and that the mutated value is much less likely to be accurate. Regardless, I’ve requested this change and am hoping for a matching adjustment in a future release for heteroplasmies.

Heteroplasmies do affect matching at the different levels.

Viewing Your Matches

Mitochondrial DNA, for testing purposes, is broken into three regions, HVR1 (hyper-variable region 1), HVR2 and the Coding Region.

At FamilyTreeDNA, you can view your matches at each level. The matches are cumulative, meaning that the HVR2 level includes the HVR1 level information, and the Coding Region level includes the HVR1 and HVR2 regions. That highest level which includes all three regions shows information from your entire your entire full mitochondrial DNA sequence.

Heteroplasmy Effects on Matching

If you otherwise match someone exactly, but one of you has a heteroplasmy and the other person carries the mutated value, you will be counted as a mismatch of 1 at the full sequence level.

A mismatch has different effects when it occurs in the HVR1, HVR2 or Coding Regions, respectively.

GD is an abbreviation for Genetic Distance which is how mutations are counted. A GD of 1 means the two people have one mutation difference between them.

In the following chart, the effects of you having a nonmatch, heteroplasmic or otherwise, in each of the regions is shown at each level. The region in which the mismatch occurs is shown in the first column, at left, and the effect the mismatch has on matching in each region is shown in columns 2-4.

The red sections are not counted as matches.

Mismatch Occurs in this Region HVR1 Level Match to Someone Else HVR2 Level Match to Someone Else Coding Region Level Match to Someone Else
HVR1 region nonmatch GD of 1 means no match GD of 1 means no match GD of 1 is a match
HVR2 region nonmatch Does not affect HVR1 – so you are a match GD of 1 means no match GD of 1 is a match
Coding Region nonmatch Does not affect HVR1 – so you are a match Does not affect HVR2 – so you are a match GD of 1 is a match

For purposes of this discussion, we’re assuming our two people being compared in the chart above match exactly on every other location so matching is not otherwise affected.

  • If your heteroplasmic nonmatch occurs in the HVR1 region – in other words, scenario 3 – you’ll fall into the HVR1 nonmatch row. That means you won’t be shown as a match at the HVR1 or HVR1+HVR2 levels, but you WILL be shown as a full sequence match.
  • If your heteroplasmic nonmatch is in the HVR2 region of addresses, it won’t affect your HVR1 matches, but it will affect your HVR2 and Coding Region matches. This means you will be shown as HVR1 match, not an HVR2 match, but will be a full sequence match.
  • If your heteroplasmic nonmatch is in the Coding Region, it won’t affect your HVR1 or HVR2 matches, but it will affect your Coding Region matches. However, it won’t preclude matches and you’ll be shown as a match in all three regions.

To be very clear, I have no issue with these match thresholds. It’s important to understand how this works, and therefore why heteroplasmic (and other) mismatches in specific regions affect our matches in the way they do.

Why Aren’t Mismatches of 1 Counted as Matches in the HVR1 or HVR2 Regions?

The match threshold at FamilyTreeDNA for the HVR1 and the HVR1+HVR2 regions, both small regions of about 1000 locations each, is that only an exact match is considered a match. Therefore, a heteroplasmic nonmatch in this region can really be confusing and sometimes misleading, especially if either or BOTH people have NOT tested at the full sequence level.

These are the match thresholds in effect today.

HVR1 GD or # of Mutations Allowed for a Match HVR2 GD or # of Mutations Allowed for a Match Coding Region GD or # of Mutations Allowed for a Match
0 – no mutations allowed 0 – no mutations allowed 3 mutations allowed

If both people match on either the heteroplasmy identified (Y in our case) or one person has the normal value – all is fine. But if one person has a heteroplasmy and the other has the mutated value – then a mismatch occurs. This is really only problematic when:

  • The heteroplasmy mismatch is in the HVR1 region and both people have only tested at that level, causing the two people to not match at all.
  • The heteroplasmy mismatch occurs in combination with other mutations that, cumulatively, push the two people over the GD 3 full sequence matching threshold.

The second scenario happens rarely, but I have seen situations where people don’t match their mothers, aunts, siblings, or other close relatives because of multiple heteroplasmic mutations occurring in different people.

And yes, this is hen’s teeth rare – but it does occasionally happen.

So, what’s the bottom line about heteroplasmies?

Heteroplasmy Bottom Line

  1. You can suspect a heteroplasmy if you have full sequence matches, but no exact matches.
  2. If you have a heteroplasmy in the HVR1 region, understand that you may not have many or any matches in the HVR1 and HVR2 regions. The remedy is to test at the full sequence level and check matches there.
  3. If you have a heteroplasmy and don’t match someone you expect to match – reach out to them and ask about their value at that specific location. If that location isn’t listed for them in their results, then they have no mutation there and your heteroplasmy is NOT the cause of you not matching with them.
  4. If you don’t match someone you expect to match, reach out to them and ask if THEY have any heteroplasmies. The easiest way to ask is, “Do you have any mutations listed that end with anything other than T, A, C, G or d?” Feel free to link to this article so that they’ll know where to look, and why you’re asking.

Do you have any heteroplasmies?

Using Mitochondrial Haplogroups at 23andMe to Pick the Lock

I’ve been writing recently about using haplogroups for genealogy, and specifically, your mitochondrial DNA haplogroup. You can check out recent articles here and here.

While FamilyTreeDNA tests the entire mitochondria and provides you with the most detailed and granular haplogroup, plus matches to other testers, 23andMe provides mid-range level haplogroup information to all testers.

I’ve been asked how testers can:

  1. Locate that information on their account
  2. What it means
  3. How to use it for genealogy

Let’s take those questions one by one. It’s actually amazing what can be done – the information you can piece together, and how you can utilize one piece of information to leverage more.

Finding Your Haplogroup Information

At 23andMe, sign in, then click on Ancestry.

Then click on Ancestry Overview.

You’ll need to scroll down until you see the haplogroup section.

If you’re a female, you don’t have a paternal haplogroup. That’s misleading, at best and I wrote about that here. If you click to view your report, you’ll simply be encouraged to purchase a DNA test for your father.

Click on the maternal haplogroup panel to view the information about your mitochondrial haplogroup.

You’ll see basic information about the haplogroup level 23andMe provides. For me, that’s J1c2.

Next, you’ll view the migration path for haplogroup J out of Africa. Haplogroup J is the great-granddaughter haplogroup of L3, an African haplogroup. Mutations occurred in L3 that gave birth to haplogroup N. More mutations gave birth to R, which gave birth to J, and so forth.

You’ll notice that haplogroup J1c2 is fairly common among 23andMe customers. This means that in my list of 1793 matches in DNA Relatives, I could expect roughly 9 to carry this base haplogroup.

There’s more interesting information.

Yes, King Richard is my long-ago cousin, of sorts. Our common mitochondrial ancestor lived in Europe, but not long after haplogroup J1c migrated from the Middle East.

One of my favorite parts of the 23andMe information is a bit geeky, I must admit.

Scroll back to the top and select Scientific Details.

Scroll down, and you’ll be able to see the haplogroup tree formation of all your ancestral haplogroups since Mitochondrial Eve who is haplogroup L. You can see L3 who migrated out of Africa, and then N and R. You can also see their “sister clades,” in blue. In other words, L3 gave birth to L3a through M, which are all sisters to N. N gave birth to R, and so forth.

On the free Public Mitochondrial Tree, provided by FamilyTreeDNA, you can see the haplogroups displayed in a different configuration, along with the countries where the most distant known ancestors of FamilyTreeDNA testers who carry that haplogroup are found. Note that only people who have taken the full sequence test are shown on this tree. You can still check out your partial haplogroup from 23andMe, but it will be compared to people who don’t have a subgroup assigned today on this public tree.

If you were to take the full sequence test at FamilyTreeDNA, you might well have a more refined haplogroup, including a subgroup. Most people do, but not everyone.

Here’s the second half of the 23andMe haplogroup tree leading from haplogroup R to J1c2, my partial haplogroup at 23andMe.

Here’s the public tree showing the J1c2 haplogroup, and my most refined haplogroup, J1c2f from my full sequence test at FamilyTreeDNA.

If you’re interested in reading more in the scientific literature about your haplogroup, at the bottom of the 23andMe Scientific Details page, you’ll see a list of references. Guaranteed to cure insomnia.😊

You’re welcome!

Using Your Haplogroup at 23andMe for Genealogy

Enjoying this information is great, but how do you actually USE this information at 23andMe for genealogy? As you already know, 23andMe does not support trees, so many times genealogists need to message our matches to determine at least some portion of their genealogy. But not always. Let’s look at different options.

While a base haplogroup is certainly interesting and CAN be used for some things, it cannot be used, at 23andMe for matching directly because only a few haplogroup-defining locations are tested.

We can use basic haplogroup information in multiple ways for genealogy, even if your matches don’t reply to messages.

23andMe no longer allows testers to filter or sort their matches by haplogroup unless you test (or retest) on the V5 platform AND subscribe yearly for $29. You can read about what you receive with the subscription, here. You can purchase a V5 test, here.

To get around the haplogroup filtering restriction, you can download your matches, which includes your matches’ haplogroups, in one place. I provided instructions for how to download your matches, here.

While 23andMe doesn’t test to a level that facilitates matching on mitochondrial alone, even just a partial haplogroup can be useful for genealogy.

You can identify the haplogroup of specific ancestors.

You can identify people who might match on a specific line based on their haplogroup. and you can use that information as a key or lever to unlock additional information. You can also eliminate connections to your matches on your matrilineal line. 

Let’s start there.

Matrilineal Line Elimination

For every match, you can view their haplogroup by clicking on their name, then scrolling down to view haplogroup information.

As you can see, Stacy does not carry the same base haplogroup as me, so our connection is NOT on our direct matrilineal line. We can eliminate that possibility. Our match could still be on our mother’s side though, just not our mother’s mother’s mother’s direct line.

If Stacy’s haplogroup was J1c2, like mine, then our connection MIGHT be through the matrilineal line. In other words, we can’t rule it out, but it requires more information to confirm that link.

Identifying My Ancestor’s Haplogroups

I’ve made it a priority to identify the mitochondrial haplogroups of as many ancestors as possible. This becomes very useful, not only for what the haplogroup itself can tell me, but to identify other matches from that line too.

click to enlarge images

Here’s my pedigree chart of my 8 great-grandparents. The colored hearts indicate whose mitochondrial DNA each person inherited. Of course, the mothers of the men in the top row would be shown in the next generation.

As you can see, I have identified the mitochondrial DNA of 6 of my 8 great-grandparents. How did I do that?

  • Testing myself
  • Searching at FamilyTreeDNA for candidates to test or who have already tested
  • Searching at Ancestry for candidates to test, particularly using ThruLines which I wrote about, here.
  • Searching at MyHeritage for candidates to test, particularly using Theories of Family Relativity which I wrote about, here
  • Searching for people from a specific line at 23andMe, although that’s challenging because 23andMee does not support traditional trees
  • Searching for people who might be descended appropriately using the 23andMe estimated “genetic tree.” Of course, then I need to send a message and cross my fingers for a reply.
  • Searching for people at WikiTree by visiting the profile of my ancestors whose mitochondrial DNA I’m searching for in the hope of discovering either someone who has already taken the mitochondrial DNA test, or who descends appropriately and would be a candidate to test

In my pedigree chart, above, the mitochondrial DNA of John Ferverda and his mother, Eva Miller, T2b, is a partial haplogroup because I discovered the descendant through 23andMe.

I was fairly certain of that match’s identity, but I need two things:

  • Confirmation of their genealogical connection to Eva Miller Ferverda
  • Someone to take the full sequence test at FamilyTreeDNA that will provide additional information

I confirmed this haplogroup by identifying a second person descended from Eva through all females to the current generation who carries the same haplogroup

Now that I’ve confirmed one person at 23andMe who descends from Eva Miller Ferverda matrilineally, and I know their mitochondrial DNA haplogroup, I can use this information to help identify other matches – even if no one responds to my messages.

This is where downloading your spreadsheet becomes essential.

Download Your Matches

Next, we’re going to work with a combination of your downloaded matches on a spreadsheet along with your matches at 23andMe on the website.

I provided step-by-step instructions for downloading your matches, here.

On the spreadsheet, you’ll see your matches and various columns for information about each match, including (but not limited to):

  • Name
  • Segment information
  • Link to tester’s profile page (so you don’t need to search for them)
  • Maternal or paternal side, but only if your parents have tested
  • Maternal haplogroup (mitochondrial DNA for everyone)
  • Paternal haplogroup (Y DNA if you’re a male)
  • Family Surnames
  • Family Locations
  • Country locations of 4 grandparents
  • Notes (that you’ve entered)
  • Link to a family tree if tester has provided that information. I wrote about how to link your tree in this article. The tree-linking instructions are still valid although 23andMe no longer partners with FamilySearch. You can link an Ancestry or MyHeritage tree.

I want to look for other people who match me and who also have haplogroup T2b, meaning they might descend from Eva Miller Ferverda, her mother, Margaret Elizabeth Lentz, or her mother, Johanne Fredericka Ruhle in the US.

To be clear, the mitochondrial DNA reaches back further in time in Germany, but since 23andMe limits matches to either your highest 1500 or 2000 matches (it’s unclear which,) minus the people who don’t opt-in to Relative Sharing, I likely wouldn’t find anyone from the German lines in the 23andMe database as matches. If you subscribe to the V5+$29 per year version of the test, you are allowed “three times as many matches” before people roll off your match list.

On the download spreadsheet, sort on the maternal column.

I have several people who match me and are members of haplogroup T2b.

Upon closer evaluation, I discovered that at least one other person does descend from Eva Miller, which confirmed that Eva’s haplogroup is indeed T2b, plus probably an unknown subclade.

I also discovered two more people who I think are good candidates to be descended from Eva Miller using the following hints:

  • Same haplogroup, T2b
  • Shared matches with other known descendants of Eva Miller, Margaret Lentz or Frederica Ruhle.
  • Triangulation with some of those known descendants

Now, I can look at each one of those matches individually to see if they triangulate with anyone else I recognize.

Do be aware that just because these people have the mitochondrial haplogroup you are seeking doesn’t necessarily mean that you’re related through that line. However, as I worked through these matches WITH the same haplogroup, I did find several that are good candidates for a common ancestor on the matrilineal line based on matches we share in common.

Let’s hope they reply, or they have tested at a different vendor that supports trees and I can recognize their name in that database.

Assign a Side

At 23andMe, one of the first important steps is to attempt to assign a parental side to each match, if possible.

If I can assign a match to a “side” of my tree based on shared matches, then I can narrow the possible haplogroups that might be of interest. In this case, I can ignore any T2b matches assigned to my father’s side.

The way to assign matches to sides, assuming you don’t have parents to test, is to look for triangulation or a group of matches with known, hopefully somewhat close, relatives.

I wrote about Triangulation Action at 23andMe, here.

For example, my top 4 matches at 23andMe are 2 people from my father’s side, and 2 people from my mother’s side, first or second cousins, so I know how we are related.

Using these matches, our “Relatives in Common,” and triangulation, I can assign many of my matches to one side or the other. “Yes” in the DNA Overlap column means me, Stacy and that person triangulate on at least one segment.

Do be careful though, because it’s certainly possible to match someone, and triangulate on one segment, but match them from your other parent’s side on a different segment.

At the very bottom of every match page (just keep scrolling) is a Notes field. Enter something. I believe, unless this has changed, that if you have entered a note, the match will NOT roll off your list, even if you’ve reached your match limit. I include as much as I do know plus a date, even if it’s “don’t know which side.” At least I know I’ve evaluated the match.

However, equally as important, when you download your spreadsheet, you’ll be able to see your own notes, so it’s easy to refer to that spreadsheet when looking at other relatives in common on your screen.

I have two monitors which makes life immensely easier.

Working the Inverse

Above, we used the haplogroup to find other matches. You can work the inverse, of course, using matches to find haplogroups.

Now that you’ve downloaded your spreadsheet, you can search in ways you can’t easily at 23andMe.

On your spreadsheet, skim locations for hints and search for the surnames associated with the ancestral line you are seeking.

Don’t stop there. Many people at 23andMe either don’t enter any information, but some enter a generation or two. Sometimes 4 surnames, one for each grandparent. If you’ve brought your lines to current genealogically, search for the surnames of the people of the lines you seek. Eva’s grandchildren who would carry her mitochondrial haplogroup would include the surnames of Robison, Gordon, and several others. I found two by referencing my descendants chart in my computer genealogy program to quickly find surnames of people descended through all females.

The link to each match’s profile page is in the spreadsheet. Click on that link to see who you match in common, and who they and you triangulate with.

Because each of the people at 23andMe does have at least a partial mitochondrial DNA haplogroup, you may be able through surname searching, or perhaps even viewing matches in common, to reveal haplogroups of your ancestors.

If you’ve already identified someone from that ancestral line, and you’re seeking that ancestor’s mitochondrial DNA, highlight the people who triangulate with the known descendant on your spreadsheet. Generation by generation, search for the surnames of that ancestor’s female grandchildren. I found one line just one generation downstream which allowed me to identify the ancestor’s haplogroup. In other words, the birth surname of my ancestor was missing, and that of her husband, but the surname of one of her granddaughters was there.

That person did indeed match and triangulate with other known descendants.

Sorting by haplogroup, at that point, showed two additional people I was able to assign to Eva’s haplogroup line and confirm through what few tidbits of genealogy the testers did provide.

I started with not knowing Eva’s haplogroup, and now I not only know she is haplogroup T2b, I’ve identified and confirmed a total of 6 people in this lineage who also have haplogroup T2b – although several descend from her mother and grandmother. I’ve also confirmed several others through this process who don’t have haplogroup T2b, but who triangulated with me and those who do. How cool is this?

I’ll be checking at FamilyTreeDNA to see if any of Eva’s T2b descendants have tested or transferred there. If I’m lucky, they’ll have already taken the mitochondrial DNA test. If not, I’ll be offering a mitochondrial DNA full sequence testing scholarship to the first one of those matches to accept.

Is this process necessarily easy?

No, but the tools certainly exist to get it done.

Is it worth it?

Absolutely.

It’s one more way to put meat on the bones of those ancestors, one tiny piece of information at a time.

I’ll be reaching out to see if perhaps any of my newly identified cousins has genealogical information, or maybe photos or stories that I don’t.

Tips and Tools

For tips and tools to work with your mitochondrial DNA haplogroups, read the article Where Did My Mitochondrial DNA Haplogroup Come From?

Please visit the Mitochondrial DNA Resource page for more information.

You can also use Genetic Affairs AutoCluster tool to assist in forming groups of related people based on your shared matches at 23andMe and FamilyTreeDNA.

What Can You Find?

What can you find at 23andMe?

Your ancestor’s haplogroups, perhaps?

Or maybe you can use known ancestral haplogroups as the key to unlocking your common ancestor with other matches.

I found an adoptee while writing this article with common triangulated matches plus haplogroup T2b, and was able to provide information about our common ancestors, including names. Their joy was palpable.

Whoever thought something like a partial haplogroup could be the gateway to so much.

23andMe tests are on sale right now for Mother’s Day, here.

Want Ancestor-Specific Ethnicity? Test Mitochondrial DNA

Recently, someone’s mitochondrial DNA test revealed that their ancestor was from Africa, but that person had no African heritage showing in their autosomal results or revealed in their genealogy.

They wondered how this was possible and which test was “wrong.” The answer is that neither test is wrong.

Mitochondrial DNA is important EXACTLY for this reason. It does not divide with inheritance, while autosomal DNA does and eventually disappears entirely.

Mitochondrial DNA is inherited from our direct matrilineal line – our mother – her mother – on up the tree directly through all mothers.

If you need a refresher, the article, 4 Kinds of DNA for Genetic Genealogy shows how different types of DNA are inherited from our ancestors.

Mitochondrial DNA and Ethnicity

Let’s look specifically at mitochondrial DNA ethnicity as compared to autosomal ethnicity.

In the chart above, an African ancestor (or ancestor of any ethnicity) who was the only ancestor of that ethnicity in your heritage is shown at the top – your five times great-grandmother. Using a 25-year generation, their autosomal DNA would have been admixed with partners of a different ethnicity 7 times between them and you.

Of course, that means the autosomal DNA of that ancestor would have been divided in (roughly) half 7 times.

Percent of Inherited Autosomal DNA

In the Percent of Inherited Autosomal DNA column, we look at it from your perspective. In other words, of the 100% of your ethnicity, stepping back each generation we can see how much of that particular ancestor you would carry. You carry 50% of your mother, 25% of your grandmother, and so forth.

You inherited approximately 0.78% of your GGGGG-Grandmother’s autosomal DNA, less than 1%.

If she was 100% African, then that 0.78% would be the only African autosomal DNA of hers that you carry, on average. You could carry a little less or a little more. We know that you don’t actually inherit exactly half of each of your ancestors’ DNA from your parents, nor they from their parents, so we can only use averages in that calculation.

Ancestral Percent Autosomal Ethnicity

In the Ancestral Percent Autosomal Ethnicity column, we look at it from the ancestor’s perspective.

Of your GGGGG-Grandmother’s 100% African ethnicity, how much would each subsequent generation be expected to inherit of that ethnicity, on average?

You would inherit 0.78% of that ancestor’s DNA. Given that GGGGG-Grandma was 100% African in this example, you would carry 0.78% African ethnicity.

Percent Mitochondrial DNA Inherited

Now, look at the Percent of Mitochondrial DNA Inherited column. Your African GGGGG-Grandmother’s mitochondrial DNA was 100% African in her generation, 7 generations ago, and still is 100% African in you, today.

That’s the beauty of mitochondrial DNA. It’s a forever record – never divided and never washes away.

How else would you EVER figure out her African roots today without records? Even if you did inherit a small amount of autosomal African DNA, and the vendor reported less than 1%, how would you determine which ancestor that African DNA came from, or when?

Not to mention trying to figure out if less than 1% or any small amount of reported ethnicity is a legitimate finding or “noise.”

What about if you, like my friend, carried no African autosomal DNA from that ancestor? There would be nothing to report in your autosomal ethnicity results – but your mitochondrial DNA would still tell the story of your African ancestor. Even after that trace is long gone in autosomal DNA.

Mitochondrial DNA is MUCH more reliable for each specific line in determining the “ethnicity” or biogeographical ancestry of each ancestor. I wrote about how to use your mitochondrial DNA haplogroup, here.

Discovering Your Forever Record

Everyone can test for their own mitochondrial DNA, and you can test other family members for their matrilineal lines as well. For example, your father or his siblings carry the mitochondrial DNA of his mother. You get the idea.

I record the mitochondrial haplogroup of each of my lines in my genealogy records and on their WikiTree profile card so others can share – now and in the future.

Genealogy research of female ancestors is less difficult with at least “one” record that reaches back where surnames and autosomal DNA don’t and can’t.

What will your mitochondrial “forever history” reveal?
