Native American & Minority Ancestors Identified Using DNAPainter Plus Ethnicity Segments

Ethnicity is always a ticklish subject. On one hand we say to be leery of ethnicity estimates, but on the other hand, we all want to know who our ancestors were and where they came from. Many people hope to prove or disprove specific theories or stories about distant ancestors.

Reasons to be cautious about ethnicity estimates include:

  • Within continents, like Europe, it’s very difficult to discern ethnicity at the “country” level because of thousands of years of migration across regions where borders exist today. Ethnicity estimates within Europe can be significantly different than known and proven genealogy.
  • “Countries,” in Europe, political constructs, are the same size as many states in the US – and differentiation between those populations is almost impossible to accurately discern. Think of trying to figure out the difference between the populations of Indiana and Illinois, for example. Yet we want to be able to tell the difference between ancestors that came from France and Germany, for example.

Ethnicity states over Europe

  • All small amounts of ethnicity, even at the continental level, under 2-5%, can be noise and might be incorrect. That’s particularly true of trace amounts, 1% or less. However, that’s not always the case – which is why companies provide those small percentages. When hunting ancestors in the distant past, that small amount of ethnicity may be the only clue we have as to where they reside at detectable levels in our genome.

Noise in this case is defined as:

  • A statistical anomaly
  • A chance combination of your DNA from both parents that matches a reference population
  • Issues with the reference population itself, specifically admixture
  • Perhaps combinations of the above

You can read about the challenges with ethnicity here and here.

On the Other Hand

Having restated the appropriate caveats, on the other hand, we can utilize legitimate segments of our DNA to identify where our ancestors came from – at the continental level.

I’m actually specifically referring to Native American admixture which is the example I’ll be using, but this process applies equally as well to other minority or continental level admixture as well. Minority, in this sense means minority ethnicity to you.

Native American ethnicity shows distinctly differently from African and European. Sometimes some segments of DNA that we inherit from Native American ancestors are reported as Asian, specifically Siberian, Northern or Eastern Asian.

Remember that the Native American people arrived as a small group via Beringia, a now flooded land bridge that once connected Siberia with Alaska.

By Erika Tamm et al – Tamm E, Kivisild T, Reidla M, Metspalu M, Smith DG, et al. (2007) Beringian Standstill and Spread of Native American Founders. PLoS ONE 2(9): e829. doi:10.1371/journal.pone.0000829. Also available from PubMed Central., CC BY 2.5, https://commons.wikimedia.org/w/index.php?curid=16975303

After that time, the Native American/First Nations peoples were isolated from Asia, for the most part, and entirely from Europe until European exploration resulted in the beginning of sustained European settlement, and admixture beginning in the late 1400s and 1500s in the Americas.

Family Inheritance

Testing multiple family members is extremely useful when working with your own personal minority heritage. This approach assumes that you’d like to identify your matches that share that genetic heritage because they share the same minority DNA that you do. Of course, that means you two share the same ancestor at some time in the past. Their genealogy, or your combined information, may hold the clue to identifying your ancestor.

In my family, my daughter has Native American segments that she inherited from me that I inherited from my mother.

Finding the same segment identified as Native American in several successive generations eliminates the possibility that the chance combination of DNA from your father and mother is “appearing” as Native, when it isn’t.

We can use segment information to our benefit, especially if we don’t know exactly who contributed that DNA – meaning which ancestor.

We need to find a way to utilize those Native or other minority segments genealogically.

23andMe

Today, the only DNA testing vendor that provides consumers with a segment identification of our ethnicity predictions is 23andMe.

If you have tested at 23andMe, sign in and click on Ancestry on the top tab, then select Ancestry Composition.

Minority ethnicity ancestry composition.png

Scroll down until you see your painted chromosomes.

Minority ethnicity chromosome painting.png

By clicking on the region at left that you want to see, the rest of the regions are greyed out and only that region is displayed on your chromosomes, at right.

Minority ethnicity Native.png

According to 23andMe, I have two Native segments, one each on chromosomes 1 and 2. They show these segments on opposite chromosomes, meaning one (the top for example) would be maternal or paternal, and the bottom one would be the opposite. But 23andMe apparently could not tell for sure because neither my mother nor father have tested there. This placement also turned out to be incorrect. The above image was my initial V3 test at 23andMe. My later V4 results were different.

Versions May Differ

Please note that your ethnicity predictions may be different based on which test you took which is dictated by when you took the test. The image above is my V3 test that was in use at 23andMe between 2010 and November 2013, and the image below is my V4 test in use between November 2013 and August 2017.

23andMe apparently does not correct original errors involving what is known as “strand swap” where the maternal and paternal segments are inverted during analysis. My V4 test results are shown below, where the strands are correctly portrayed.

Minority ethnicity Native V4.png

Note that both Native segments are now on the lower chromosome “side” of the pair and the position on the chromosome 1 segment has shifted visually.

Minority ethnicity sides.png

I have not tested at 23andMe on the current V5 GSA chip, in use since August 9, 2017, but perhaps I should. The results might be different yet, with the concept being that each version offers an improvement over earlier versions as science advances.

If your parents have tested, 23andMe makes adjustments to your ethnicity estimates accordingly.

Although my mother can’t test at 23andMe, I happen to already know that these Native segments descend from my mother based on genealogical and genetic analysis, combined. I’m going to walk you through the process.

I can utilize my genealogy to confirm or refute information shown by 23andMe. For example, if one of those segments comes from known ancestors who were living in Germany, it’s clearly not Native, and it’s noise of some type.

We’re going to utilize DNAPainter to determine which ancestors contributed your minority segments, but first you’ll need to download your ethnicity segments from 23andMe.

Downloading Ethnicity Segment Data

Downloading your ethnicity segments is NOT THE SAME as downloading your raw DNA results to transfer to another vendor. Those are two entirely different files and different procedures.

To download the locations of your ethnicity segments at 23andMe, scroll down below your painted ethnicity segments in your Ancestry Composition section to “View Scientific Details.”

MInority ethnicity scientific details.png

Click on View Scientific Details and scroll down to near the bottom and then click on “Download Raw Data.” I leave mine at the 50% confidence level.

Minority ethnicity download raw data.png

Save this spreadsheet to your computer in a known location.

In the spreadsheet, you’ll see columns that provide the name of the segment, the chromosome copy number (1 or 2) and the chromosome number with start and end locations.

Minority ethnicity download.png

You really don’t care about this information directly, but DNAPainter does and you’ll care a lot about what DNAPainter does for you.

DNAPainter

I wrote introductory articles about DNAPainter:

If you’re not familiar with DNAPainter, you might want to read these articles first and then come back to this point in this article.

Go ahead – I’ll wait!

Getting Started

If you don’t have a DNAPainter account, you’ll need to create one for free. Some features, such as having multiple profiles are subscription based, but the functionality you’ll need for one profile is free.

I’ve named this example profile “Ethnicity Demo.” You’ll see your name where mine says “Ethnicity Demo.”

Minority ethnicity DNAPainter.png

Click on “Import 23andme ancestry composition.”

You will copy and paste all the spreadsheet rows in the entire downloaded 23andMe ethnicity spreadsheet into the DNAPainter text box and make your selection, below. The great news is that if you discover that your assumption about copy 1 being maternal or paternal is incorrect, it’s easy to delete the ethnicity segments entirely and simply repaint later. Ditto if 23andMe changes your estimate over time, like they have mine.

Minority ethnicity DNAPainter sides.png

I happen to know that “copy 2” is maternal, so I’ve made that selection.

You can then see your ethnicity chromosome segments painted, and you can expand each one to see the detail. Click on “Save Segments.”

MInority ethnicity DNAPainter Native painting

In this example, you can see my Native segments, called by various names at different confidence levels at 23andMe, on chromosome 1.

Depending on the confidence level, these segments are called some mixture of:

  • East Asian & Native American
  • North Asian & Native American
  • Native American
  • Broadly East Asian & Native American

It’s exactly the same segment, so you don’t really care what it’s called. DNAPainter paints all of the different descriptions provided by 23andMe, at all confidence levels as you can see above.

The DNAPainter colors are different from 23andMe colors and are system-selected. You can’t assign the colors for ethnicity segments.

Now, I’m moving to my own profile that I paint with my ancestral segments. To date, I have 78% of my segments painted by identifying cousins with known common ancestors.

On chromosomes 1 and 2, copy 2, which I’ve determined to be my mother’s “side,” these segments track back to specific ancestors.

Minority ethnicity maternal side

Chromosome 1 segments, above, track back to the Lore family, descended from Antoine (Anthony) Lore (Lord) who married Rachel Hill. Antoine Lore was Acadian.

Minority ethnicity chromosome 1.png

Clicking on the green segment bar shows me the ancestors I assigned when I painted the match with my Lore family member whose name is blurred, but whose birth surname was Lore.

The Chromosome 2 segment, below, tracks back to the same family through a match to Fred.

Minority ethnicity chromosome 2.png

My common ancestors with Fred are Honore Lore and Marie Lafaille who are the parents of Antoine Lore.

Minority ethnicity common ancestor.png

There are additional matches on both chromosomes who also match on portions of the Native segments.

Now that I have a pointer in the ancestral direction that these Native American segments arrived from, what can traditional genealogy and other DNA information tell me?

Traditional Genealogy Research

The Acadian people were a mixture of English, French and Native American. The Acadians settled on the island of Nova Scotia in 1609 and lived there until being driven out by the English in 1755, roughly 6 or 7 generations later.

Minority ethnicity Acadian map.png

The Acadians intermarried with the Mi’kmaq people.

It had been reported by two very qualified genealogists that Philippe Mius, born in 1660, married two Native American women from the Mi’kmaq tribe given the name Marie.

The French were fond of giving the first name of Marie to Native women when they were baptized in the Catholic faith which was required before the French men were allowed to marry the Native women. There were many Native women named Marie who married European men.

Minority ethnicity Native mitochondrial tree

Click to enlarge

This Mius lineage is ancestral to Antoine Lore (Lord) as shown on my pedigree, above.

Mitochondrial DNA has revealed that descendants from one of Philippe Mius’s wives, Marie, carry haplogroup A2f1a.

However, mitochondrial tests of other descendants of “Marie,” his first wife, carry haplogroup X2a2, also Native American.

Confusion has historically existed over which Marie is the mother of my ancestor, Francoise.

Karen Theroit Reader, another professional genealogist, shows Francoise Mius as the last child born to the first Native wife before her death sometime after 1684 and before about 1687 when Philippe remarried.

However, relative to the source of Native American segments, whether Francoise descends from the first or second wife doesn’t matter in this instance because both are Native and are proven so by their mitochondrial DNA haplogroups.

Additionally, on Antoine’s mother’s side, we find a Doucet male, although there are two genetic male Doucet lines, one of European origin, haplogroup R-L21, and one, surprisingly, of Native origin, haplogroup C-P39. Both are proven by their respective haplogroups but confusion exists genealogically over who descends from which lineage.

On Antoine’s mother’s side, there are several unidentified lineages, any one or multiples of which could also be Native. As you can see, there are large gaps in my tree.

We do know that these Native segments arrived through Antoine Lore and his parents, Honore Lore and Marie LaFaille. We don’t know exactly who upstream contributed these segments – at least not yet. Painting additional matches attributable to specific ancestral couples will eventually narrow the candidates and allow me to walk these segments back in time to their rightful contributor.

Segments, Traditional Research and DNAPainter

These three tools together, when using continent-level segments in combination with painting the DNA segments of known cousins that match specific lineages create a triangulated ethnicity segment.

When that segment just happens to be genealogically important, this combination can point the researchers in the right direction knowing which lines to search for that minority ancestor.

If your cousins who match you on this segment have also tested with 23andMe, they should also be identified as Native on this same segment. This process does not apply to intracontinental segments, meaning within Europe, because the admixture is too great and the ethnicity predictions are much less reliable.

When identifying minority admixture at the continental level, adding Y and mitochondrial DNA testing to the mix in order to positively identify each individual ancestor’s Y and mitochondrial DNA is very important in both eliminating and confirming what autosomal DNA and genealogy records alone can’t do. The base haplogroup as assigned at 23andMe is a good start, but it’s not enough alone. Plus, we only carry one line of mitochondrial DNA and only males carry Y DNA, and only their direct paternal line.

We need Y and mitochondrial DNA matching at FamilyTreeDNA to verify the specific lineage. Additionally, we very well may need the Y and mitochondrial DNA information that we don’t directly carry – but other cousins do. You can read about Y and mitochondrial DNA testing, here.

I wrote about creating a personal DNA pedigree chart including your ancestors’ Y and mitochondrial DNA here. In order to find people descended from a specific ancestor who have DNA tested, I utilize:

  • WikiTree resources and trees
  • Geni trees
  • FamilySearch trees
  • FamilyTreeDNA autosomal matches with trees
  • AncestryDNA autosomal matches and their associated trees
  • Ancestry trees in general, meaning without knowing if they are related to a DNA match
  • MyHeritage autosomal matches and their trees
  • MyHeritage trees in general

At both MyHeritage and Ancestry, you can view the trees of your matches, but you can also search for ancestors in other people’s trees to see who might descend appropriately to provide a Y or mitochondrial DNA sample. You will probably need a subscription to maximize these efforts. My Heritage offers a free trial subscription here.

If you find people appropriately descended through WikiTree, Geni or FamilySearch, you’ll need to discuss DNA testing with them. They may have already tested someplace.

If you find people who have DNA tested through your DNA matches with trees at Ancestry and MyHeritage, you’ll need to offer a Y or mitochondrial DNA test to them if they haven’t already tested at FamilyTreeDNA.

FamilyTreeDNA is the only vendor who provides the Y DNA and mitochondrial DNA tests at the higher resolution level, beyond base haplogroups, required for matching and for a complete haplogroup designation.

If the person has taken the Family Finder autosomal test at FamilyTreeDNA, they may have already tested their Y DNA and mtDNA, or you can offer to upgrade their test.

Projects

Checking projects at FamilyTreeDNA can be particularly useful when trying to discover if anyone from a specific lineage has already tested. There are many, special interest projects such as the Acadian AmerIndian Ancestry project, the American Indian project, haplogroup projects, surname projects and more.

You can view projects alphabetically here or you can click here to scroll down to enter the surname or topic you are seeking.

Minority ethnicity project search.png

If the topic isn’t listed, check the alphabetic index under Geographical Projects.

23andMe Maternal and Paternal Sides

If possible, you’ll want to determine which “side” of your family your minority segments originate come from, unless they come from both. you’ll want to determine whether chromosome side one 1 or 2 is maternal, because the other one will be paternal.

23andMe doesn’t offer tree functionality in the same way as other vendors, so you won’t be able to identify people there descended from your ancestors without contacting each person or doing other sleuthing.

Recently, 23andMe added a link to FamilySearch that creates a list of your ancestors from their mega-shared tree for 7 generations, but there is no tree matching or search functionality. You can read about the FamilySearch connection functionality here.

So, how do you figure out which “side” is which?

Minority ethnicity minority segment.png

The chart above represents the portion of your chromosomes that contains your minority ancestry. Initially, you don’t know if the minority segment is your mother’s pink chromosome or your father’s blue chromosome. You have one chromosome from each parent with the exact same addresses or locations, so it’s impossible to tell which side is which without additional information. Either the pink or the blue segment is minority, but how can you tell?

In my case, the family oral history regarding Native American ancestry was from my father’s line, but the actual Native segments wound up being from my mother, not my father. Had I made an assumption, it would have been incorrect.

Fortunately, in our example, you have both a maternal and paternal aunt who have tested at 23andMe. You match both aunts on that exact same segment location – one from your father’s side, blue, and one from your mother’s side, pink.

You compare your match with your maternal aunt and verify that indeed, you do match her on that segment.

You’ll want to determine if 23andMe has flagged that segment as Native American for your maternal aunt too.

You can view your aunt’s Ancestry Composition by selecting your aunt from the “Your Connections” dropdown list above your own ethnicity chromosome painting.

Minority ethnicity relative connections.png

You can see on your aunt’s chromosomes that indeed, those locations on her chromosomes are Native as well.

Minority ethnicity relative minority segments.png

Now you’ve identified your minority segment as originating on your maternal side.

Minority ethnicity Native side.png

Let’s say you have another match, Match 1, on that same segment. You can easily tell which “side” Match 1 is from. Since you know that you match your maternal aunt on that minority segment, if Match 1 matches both you and your maternal aunt, then you know that’s the side the match is from – AND that person also shares that minority segment.

You can also view that person’s Ancestry Composition as well, but shared matching is more reliable,especially when dealing with small amounts of minority admixture.

Another person, Match 2, matches you on that same segment, but this time, the person matches you and your paternal aunt, so they don’t share your minority segment.

Minority ethnicity match side.png

Even if your paternal aunt had not tested, because Match 2 does not match you AND your maternal aunt, you know Match 2 doesn’t share your minority segment which you can confirm by checking their Ancestry Composition.

Download All of Your Matches

Rather than go through your matches one by one, it’s easiest to download your entire match list so you can see which people match you on those chromosome locations.

Minority ethnicity download aggregate data.png

You can click on “Download Aggregate Data” at 23andMe, at the bottom of your DNA Relatives match list to obtain all of your matches who are sharing with you. 23andMe limits your matches to 2000 or less, the actual number being your highest 2000 matches minus the people who aren’t sharing. I have 1465 matches showing and that number decreases regularly as new testers at 23andMe are focused on health and not genealogy, meaning lower matches get pushed off the list of 2000 match candidates.

You can quickly sort the spreadsheet to see who matches you on specific segments. Then, you can check each match in the system to see if that person matches you and another known relative on the minority segments or you can check their Ancestry Composition, or both.

If they share your minority segment, then you can check their tree link if they have one, included in the download, their Family Search information if included on their account, or reach out to them to see if you might share a known ancestor.

The key to making your ethnicity segment work for you is to identify ancestors and paint known matches.

Paint Those Matches

When searching for matches whose DNA you can attribute to specific ancestors, be sure to check at all 4 places that provide segment information that you can paint:

At GedMatch, you’ll find some people who have tested at the other various vendors, including Ancestry, but unfortunately not everyone uploads. Ancestry doesn’t provide segment information, so you won’t be able to paint those matches directly from Ancestry.

If your Ancestry matches transfer to GedMatch, FamilyTreeDNA or MyHeritage you can view your match and paint your common segments. At GedMatch, Ancestry kit numbers begin with an A. I use my Ancestry kit matches at GedMatch to attempt to figure out who that match is at Ancestry in order to attempt to figure out the common ancestor.

To Paint, You Must Test

Of course, in order to paint your matches that you find in various databases, you need to be in those data bases, meaning you either need to test there or transfer your DNA file.

Transfers

If you’d like to test your DNA at one vendor and download the file to transfer to another vendor, or GedMatch, that’s possible with both FamilyTreeDNA and MyHeritage who both accept uploads.

You can transfer kits from Ancestry and 23andMe to both FamilyTreeDNA and MyHeritage for free, although the chromosome browsers, advanced tools and ethnicity require an unlock fee (or alternatively a subscription at MyHeritage). Still, the free transfer and unlock for $19 at FamilyTreeDNA or $29 at MyHeritage is less than the cost of testing.

Here’s a quick cheat sheet.

DNA vendor transfer cheat sheet 2019

From time to time, as vendor file formats change, the ability to transfer is temporarily interrupted, but it costs nothing to try a transfer to either MyHeritage or FamilyTreeDNA, or better yet, both.

In each of these articles, I wrote about how to download your data from a specific vendor and how to upload from other vendors if they accept uploads.

Summary Steps

In order to use your minority ethnicity segments in your genealogy, you need to:

  1. Test at 23andMe
  2. Identify which parental side your minority ethnicity segments are from, if possible
  3. Download your ethnicity segments
  4. Establish a DNAPainter account
  5. Upload your ethnicity segments to DNAPainter
  6. Paint matches of people with whom you share known common ancestors utilizing segment information from 23andMe, FamilyTreeDNA, MyHeritage and AncestryDNA matches who have uploaded to GedMatch
  7. If you have not tested at either MyHeritage or FamilyTreeDNA, upload your 23andMe file to either vendor for matching, along with GedMatch
  8. Focus on those minority segments to determine which ancestral line they descend through in order to identify the ancestor(s) who provided your minority admixture.

Have fun!

First Steps When Your DNA Results are Ready – Sticking Your Toe in the Genealogy Water

First steps helix

Recently someone asked me what the first steps would be for a person who wasn’t terribly familiar with genealogy and had just received their DNA test results.

I wrote an article called DNA Results – First Glances at Ethnicity and Matching which was meant to show new folks what the various vendor interfaces look like. I was hoping this might whet their appetites for more, meaning that the tester might, just might, stick their toe into the genealogy waters😊

I’m hoping this article will help them get hooked! Maybe that’s you!

A Guide

This article can be read in one of two ways – as an overview, or, if you click the links, as a pretty thorough lesson. If you’re new, I strongly suggest reading it as an overview first, then a second time as a deeper dive. Use it as a guide to navigate your results as you get your feet wet.

I’ll be hotlinking to various articles I’ve written on lots of topics, so please take a look at details (eventually) by clicking on those links!

This article is meant as a guideline for what to do, and how to get started with your DNA matching results!

If you’re looking for ethnicity information, check out the First Glances article, plus here and here and here.

Concepts – Calculating Ethnicity Percentages provides you with guidelines for how to estimate your own ethnicity percentages based on your known genealogy and Ethnicity Testing – A Conundrum explains how ethnicity testing is done.

OK, let’s get started. Fun awaits!

The Goal

The goal for using DNA matching in genealogy depends on your interests.

  1. To discover cousins and family members that you don’t know. Some people are interested in finding and meeting relatives who might have known their grandparents or great-grandparents in the hope of discovering new family information or photos they didn’t know existed previously. I’ve been gifted with my great-grandparent’s pictures, so this strategy definitely works!
  2. To confirm ancestors. This approach presumes that you’ve done at least a little genealogy, enough to construct at least a rudimentary tree. Ancestors are “confirmed” when you DNA match multiple other people who descend from the same ancestor through multiple children. I wrote an article, Ancestors: What Constitutes Proof?, discussing how much evidence is enough to actually confirm an ancestor. Confirmation is based on a combination of both genealogical records and DNA matching and it varies depending on the circumstances.
  3. Adoptees and people with unknown parents seeking to discover the identities of those people aren’t initially looking at their own family tree – because they don’t have one yet. The genealogy of others can help them figure out the identity of those mystery people. I wrote about that technique in the article, Identifying Unknown Parents and Individuals Using DNA Matching.

DNAAdoption for Everyone

Educational resources for adoptees and non-adoptees alike can be found at www.dnaadoption.org. DNAAdoption is not just for adoptees and provides first rate education for everyone. They also provide trained and mentored search angels for adoptees who understand the search process along with the intricacies of navigating the emotional minefield of adoption and unknown parent searches.

First Look” classes for each vendor are free for everyone at DNAAdoption and are self-paced, downloadable onto your computer as a pdf file. Intro to DNA, Applied Autosomal DNA and Y DNA Basics classes are nominally priced at between $29 and $49 and I strongly recommend these. DNAAdoption is entirely non-profit, so your class fee or contribution supports their work. Additional resources can be found here and their 12 adoptee search steps here.

Ok, now let’s look at your results.

Matches are the Key

Regardless of your goal, your DNA matches are the key to finding answers, whether you want to make contact with close relatives, prove your more distant ancestors or you’re involved in an adoptee or unknown parent search.

Your DNA matches that of other people because each of you inherited a piece of DNA, called a segment, where many locations are identical. The length of that DNA segment is measured in centiMorgans and those locations are called SNPs, or single nucleotide polymorphisms. You can read about the definition of a centimorgan and how they are used in the article Concepts – CentiMorgans, SNPs and Pickin’Crab.

While the scientific details are great, they aren’t important initially. What is important is to understand that the more closely you match someone, the more closely you are related to them. You share more DNA with close relatives than more distant relatives.

For example, I share exactly half of my mother’s DNA, but only about 25% of each of my grandparents’ DNA. As the relationships move further back in time, I share less and less DNA with other people who descend from those same ancestors.

Informational Tools

Every vendor’s match page looks different, as was illustrated in the First Glances article, but regardless, you are looking for four basic pieces of information:

  • Who you match
  • How much DNA you share with your match
  • Who else you and your match share that DNA with, which suggests that you all share a common ancestor
  • Family trees to reveal the common ancestor between people who match each other

Every vendor has different ways of displaying this information, and not all vendors provide everything. For example, 23andMe does not support trees, although they allow you to link to one elsewhere. Ancestry does not provide a tool called a chromosome browser which allows you to see if you and others match on the same segment of DNA. Ancestry only tells you THAT you match, not HOW you match.

Each vendor has their strengths and shortcomings. As genealogists, we simply need to understand how to utilize the information available.

I’ll be using examples from all 4 major vendors:

Your matches are the most important information and everything else is based on those matches.

Family Tree DNA

I have tested many family members from both sides of my family at Family Tree DNA using the Family Finder autosomal test which makes my matches there incredibly useful because I can see which family members, in addition to me, my matches match.

Family Tree DNA assigns matches to maternal and paternal sides in a unique way, even if your parents haven’t tested, so long as some close relatives have tested. Let’s take a look.

First Steps Family Tree DNA matches.png

Sign on to your account and click to see your matches.

At the top of your Family Finder matches page, you’ll see three groups of things, shown below.

First Steps Family Tree DNA bucketing

Click to enlarge

A row of tools at the top titled Chromosome Browser, In Common With and Not in Common With.

A second row of tabs that include All, Paternal, Maternal and Both. These are the maternal and paternal tabs I mentioned, meaning that I have a total of 4645 matches, 988 of which are from my paternal side and 847 of which are from my maternal side.

Family Tree DNA assigns people to these “buckets” based on matches with third cousins or closer if you have them attached in your tree. This is why it’s critical to have a tree and test close relatives, especially people from earlier generations like aunts, uncles, great-aunts/uncles and their children if they are no longer living.

If you have one or both parents that can test, that’s a wonderful boon because anyone who matches you and one of your parents is automatically bucketed, or phased (scientific term) to that parent’s side of the tree. However, at Family Tree DNA, it’s not required to have a parent test to have some matches assigned to maternal or paternal sides. You just need to test third cousins or closer and attach them to the proper place in your tree.

How does bucketing work?

Maternal or Paternal “Side” Assignment, aka Bucketing

If I match a maternal first cousin, Cheryl, for example, and we both match John Doe on the same segment, John Doe is automatically assigned to my maternal bucket with a little maternal icon placed beside the match.

First Steps Family Tree DNA match info

Click to enlarge

Every vendor provides an estimated or predicted relationship based on a combination of total centiMorgans and the longest contiguous matching segment. The actual “linked relationship” is calculated based on where this person resides in your tree.

The common surnames at far right are a very nice features, but not every tester provides that information. When the testers do include surnames at Family Tree DNA, common surnames are bolded. Other vendors have similar features.

People with trees are shown near their profile picture with a blue pedigree icon. Clicking on the pedigree icon will show you their ancestors. Your matches estimated relationship to you indicates how far back you should expect to share an ancestor.

For example, first cousins share grandparents. Second cousins share great-grandparents. In general, the further back in time your common ancestor, the less DNA you can be expected to share.

You can view relationship information in chart form in my article here or utilize DNAPainter tools, here, to see the various possibilities for the different match levels.

Clicking on the pedigree chart of your match will show you their tree. In my tree, I’ve connected my parents in their proper places, along with Cheryl and Don, mother’s first cousins. (Yes, they’ve given permission for me to utilize their results, so they aren’t always blurred in images.)

Cheryl and Don are my first cousins once removed, meaning my mother is their first cousin and I’m one generation further down the tree. I’m showing the amount of DNA that I share with each of them in red in the format of total DNA shared and longest unbroken segment, taken from the match list. So 382-53 means I share a total of 382 cM and 53 cM is the longest matching block.

First Steps Family Tree DNA tree.png

The Chromosome Browser

Utilizing the chromosome browser, I can see exactly where I match both Don and Cheryl. It’s obvious that I match them on at least some different pieces of my DNA, because the total and longest segment amounts are different.

The reason it’s important to test lots of close relatives is because even siblings inherit different pieces of DNA from their parents, and they don’t pass the same DNA to their offspring either – so in each generation the amount of shared DNA is probably reduced. I say probably because sometimes segments are passed entirely and sometimes not at all, which is how we “lose” our ancestors’ DNA over the generations.

Here’s a matching example utilizing a chromosome browser.

First Steps Family Tree DNA chromosome browser.png

I clicked the checkboxes to the left of both Cheryl and Don on the match page, then the Chromosome Browser button, and now you can see, above, on chromosomes 1-16 where I match Cheryl (blue) and Don (red.)

In this view, both Don and Cheryl are being compared to me, since I’m the one signed in to my account and viewing my DNA matches. Therefore, one of the bars at each chromosome represents Don’s DNA match to me and one represents Cheryl’s. Cheryl is the first person and Don is the second. Person match colors (red and blue) are assigned arbitrarily by the system.

My grandfather and Cheryl/Don’s father, Roscoe, were siblings.

You can see that on some segments, my grandfather and Roscoe inherited the same segment of DNA from their parents, because today, my mother gave me that exact same segment that I share with both Don and Cheryl. Those segments are exactly identical and shown in the black boxes.

The only way for us to share this DNA today is for us to have shared a common ancestor who gave it to two of their children who passed it on to their descendants who DNA tested today.

On other segments, in red boxes, I share part of the same segments of DNA with Cheryl and Don, but someone along the line didn’t inherit all of that segment. For example on chromosome 3, in the red box, you can see that I share more with Cheryl (blue) than Don (red.)

In other cases, I share with either Don or Cheryl, but Don and Cheryl didn’t inherit that same segment of DNA from their father, so I don’t share with both of them. Those are the areas where you see only blue or only red.

On chromosome 12, you can see where it looks like Don’s and Cheryl’s segments butt up against each other. The DNA was clearly divided there. Don received one piece and Cheryl got the other. That’s known as a crossover and you can read about crossovers here, if you’d like.

It’s important to be able to view segment information to be able to see how others match in order to identify which common ancestor that DNA came from.

In Common With

You can use the “In Common With” tool to see who you match in common with any match. My first 6 matches in common with Cheryl are shown below. Note that they are already all bucketed to my maternal side.

First Steps Family Tree DNA in common with

click to enlarge

You can click on up to 7 individuals in the check box at left to show them on the chromosome browser at once to see if they match you on common segments.

Each matching segment has its own history and may descend from a different ancestor in your common tree.

First Steps 7 match chromosome browser

click to enlarge

If combinations of people do match me on a common segment, because these matches are all on my maternal side, they are triangulated and we know they have to descend from a common ancestor, assuming the segment is large enough. You can read about the concept of triangulation here. Triangulation occurs when 3 or more people (who aren’t extremely closely related like parents or siblings) all match each other on the same reasonably sized segment of DNA.

If you want to download your matches and work through this process in a spreadsheet, that’s an option too.

Size Matters

Small segments can be identical by chance instead of identical by descent.

  • “Identical by chance” means that you accidentally match someone because your DNA on that segment has been combined from both parents and causes it to match another person, making the segment “looks like” it comes from a common ancestor, when it really doesn’t. When DNA is sequenced, both your mother and father’s strands are sequenced, meaning that there’s no way to determine which came from whom. Think of a street with Mom’s side and Dad’s side with identical addresses on the houses on both sides. I wrote about that here.
  • “Identical by descent” means that the DNA is identical because it actually descends from a common ancestor. I discussed that concept in the article, We Match, But Are We Related.

Generally, we only utilize 7cM (centiMorgan) segments and above because at that level, about half of the segments are identical by descent and about half are identical by chance, known as false positives. By the time we move above 15 cM, most, but not all, matches are legitimate. You can read about segment size and accuracy here.

Using “In Common With” and the Matrix

“In Common With” is about who shares DNA. You can select someone you match to see who else you BOTH match. Just because you match two other people doesn’t necessarily mean that it’s on the same segment of DNA. In fact, you could match one person from your mother’s side and the other person from your father’s side.

First Steps match matrix.png

In this example, you match Person B due to ancestor John Doe and Person C due to ancestor Susie Smith. However, Person B also matches person C, but due to ancestor William West that they share and you don’t.

This example shows you THAT they match, but not HOW they match.

The only way to assure that the matches between the three people above are due to the same ancestor is to look at the segments with a chromosome browser and compare all 3 people to each other. Finding 3 people who match on the same segment, from the same side of your tree means that (assuming a reasonably large segment) you share a common ancestor.

Family Tree DNA has a nice matrix function that allows you to see which of your matches also match each other.

First steps matrix link

click to enlarge

The important distinction between the matrix and the chromosome browser is that the chromosome browser shows you where your matches match you, but those matches could be from both sides of your tree, unless they are bucketed. The matrix shows you if your matches also match each other, which is a huge clue that they are probably from the same side of your tree.

First Steps Family Tree DNA matrix.png

A matrix match is a significant clue in terms of who descends from which ancestors. For example, I know, based on who Amy matches, and who she doesn’t match, that she descends from the Ferverda side and that Charles, Rex and Maxine descend from ancestors on the Miller side.

Looking in the chromosome browser, I can tell that Cheryl, Don, Amy and I match on some common segments.

Matching multiple people on the same segment that descends from a common ancestor is called triangulation.

Let’s take a look at the MyHeritage triangulation tool.

MyHeritage

Moving now to MyHeritage who provides us with an easy to use triangulation tool, we see the following when clicking on DNA matches on the DNA tab on the toolbar.

First Steps MyHeritage matches

click to enlarge

Cousin Cheryl is at MyHeritage too. By clicking on Review DNA Match, the purple button on the right, I can see who else I match in common with Cheryl, plus triangulation.

The list of people Cheryl and I both match is shown below, along with our relationships to each person.

First Steps MyHeritage triangulation

click to enlarge

I’ve selected 2 matches to illustrate.

The first match has a little purple icon to the right which means that Amy triangulates with me and Cheryl.

The second match, Rex, means that while we both match Rex, it’s not on the same segment. I know that without looking further because there is no triangulation button. We both match Rex, but Cheryl matches Rex on a different segment than I do.

Without additional genealogy work, using DNA alone, I can’t say whether or not Cheryl, Rex and I all share a common ancestor. As it turns out, we do. Rex is a known cousin who I tested. However, in an unknown situation, I would have to view the trees of those matches to make that determination.

Triangulation

Clicking on the purple triangulation icon for Amy shows me the segments that all 3 of us, me, Amy and Cheryl share in common as compared to me.

First Steps MyHeritage triangulation chromosome browser.png

Cheryl is red and Amy is yellow. The one segment bracketed with the rounded rectangle is the segment shared by all 3 of us.

Do we have a common ancestor? I know Cheryl and I do, but maybe I don’t know who Amy is. Let’s look at Amy’s tree which is also shown if I scroll down.

First Steps MyHeritage common ancestor.png

Amy didn’t have her tree built out far enough to show our common ancestor, but I immediately recognized the surname Ferveda found in her tree a couple of generations back. Darlene was the daughter of Donald Ferverda who was the son of Hiram Ferverda, my great-grandfather.

Hiram was the father of Cheryl’s father, Roscoe and my grandfather, John Ferverda.

First Steps Hiram Ferverda pedigree.png

Amy is my first cousin twice removed and that segment of DNA that I share with her is from either Hiram Ferverda or his wife Eva Miller.

Now, based on who else Amy matches, I can probably tell whether that segment descends from Hiram or Eva.

Viva triangulation!

Theory of Family Relativity

MyHeritage’s Theory of Family Relativity provides theories to people whose DNA matches regarding their common ancestor if MyHeritage can calculate how the 2 people are potentially related.

MyHeritage uses a combination of tools to make that connection, including:

  • DNA matches
  • Your tree
  • Your match’s tree
  • Other people’s trees at MyHeritage, FamilySearch and Geni if the common ancestor cannot be found in your tree compared against your DNA match’s MyHeritage
  • Documents in the MyHeritage data collection, such as census records, for example.

MyHeritage theory update

To view the Theories, click on the purple “View Theories” banner or “View theory” under the DNA match.

First Steps MyHeritage theory of relativity

The theory is displayed in summary format first.

MyHeritage view full theory

You can click on the “View Full Theory” to see the detail and sources about how MyHeritage calculated various paths. I have up to 5 different theories that utilize separate resources.

MyHeritage review match

click to enlarge

A wonderful aspect of this feature is that MyHeritage shows you exactly the information they utilized and calculates a confidence factor as well.

All theories should be viewed as exactly that and should be evaluated critically for accuracy, taking into consideration sources and documentation.

I wrote about using Theories of Relativity, with instructions, here and here.

I love this tool and find the Theories mostly accurate.

AncestryDNA

Ancestry doesn’t offer a chromosome browser or triangulation but does offer a tree view for people that you match, so long as you have a subscription. In the past, a special “Light” subscription for DNA only was available for approximately $49 per year that provided access to the trees of your DNA matches and other DNA-related features. You could not order online and had to call support, sometimes asking for a supervisor in order to purchase that reduced-cost subscription. The “Light” subscription did not provide access to anything outside of DNA results, meaning documents, etc. I don’t know if this is still available.

After signing on, click on DNA matches on the DNA tab on the toolbar.

You’ll see the following match list.

First Steps Ancestry matches

click to enlarge

I’ve tested twice at Ancestry, the second time when they moved to their new chip, so I’m my own highest match. Click on any match name to view more.

First Steps Ancestry shared matches

click to enlarge

You’ll see information about common ancestors if you have some in your trees, plus the amount of shared DNA along with a link to Shared Matches.

I found one of the same cousins at Ancestry whose match we were viewing at MyHeritage, so let’s see what her match to me at Ancestry looks like.

Below are my shared matches with that cousin. The notes to the right are mine, not provided by Ancestry. I make extensive use of the notes fields provided by the vendors.

First Steps Ancestry shared matches with cousin

click to enlarge

On your match list, you can click on any match, then on Shared Matches to see who you both match in common. While Ancestry provides no chromosome browser, you can see the amount of DNA that you share and trees, if any exist.

Let’s look at a tree comparison when a common ancestor can be detected in a tree within the past 7 generations.

First Steps Ancestry view ThruLines.png

What’s missing of course is that I can’t see how we match because there’s no chromosome browser, nor can I see if my matches match each other.

Stitched Trees

What I can see, if I click on “View ThruLines” above or ThruLines on the DNA Summary page on the main DNA tab is all of the people I match who Ancestry THINKS we descend from a common ancestor. This ancestor information isn’t always taken from either person’s tree.

For example, if my match hadn’t included Hiram Ferverda in her tree, Ancestry would use other people’s trees to “stitch them together” such that the tester is shown to be descended from a common ancestor with me. Sometimes these stitched trees are accurate and sometimes they are not, although they have improved since they were first released. I wrote about ThruLines here.

First Steps Ancestry ThruLines tree

click to enlarge

In closer generations, especially if you are looking to connect with cousins, tree matching is a very valuable tool. In the graphic above, you can see all of the cousins who descend from Hiram Ferverda who have tested and DNA match to me. These DNA matches to me either descend from Hiram according to their trees, or Ancestry believes they descend from Hiram based on other people’s trees.

With more distant ancestors, other people’s trees are increasingly likely to be copied with no sources, so take them with a very large grain of salt (perchance the entire salt lick.) I use ThruLines as hints, not gospel, especially the further back in time the common ancestor. I wish they reached back another couple of generations. They are great hints and they end with the 7th generation where my brick walls tend to begin!

23andMe

I haven’t mentioned 23andMe yet in this article. Genealogists do test there, especially adoptees who need to fish in every pond.

23andMe is often the 4th choice of the major 4 vendors for genealogy due to the following challenges:

  • No tree support, other than allowing you to link to a tree at FamilySearch or elsewhere. This means no tree matching.
  • Less than 2000 matches, meaning that every person is limited to a maximum of 2000 matches, minus however many of those 2000 don’t opt-in for genealogical matching. Given that 23andMe’s focus is increasingly health, my number of matches continues to decrease and is currently just over 1500. The good news is that those 1500 are my highest, meaning closest matches. The bad news is the genealogy is not 23andMe’s focus.

If you are an adoptee, a die-hard genealogist or specifically interested in ethnicity, then test at 23andMe. Otherwise all three of the other vendors would be better choices.

However, like the other vendors, 23andMe does have some features that are unique.

Their ethnicity predictions are acknowledged to be excellent. Ethnicity at 23andMe is called Ancestry Composition, and you’ll see that immediately when you sign in to your account.

First Steps 23andMe DNA Relatives.png

Your matches at 23andMe are found under DNA Relatives.

First Steps 23andMe tools

click to enlarge

At left, you’ll find filters and the search box.

Mom’s and Dad’s side filter matches if you’ve tested your parents, but it’s not like the Family Tree DNA bucketing that provides maternal and paternal side bucketing by utilizing through third cousins if your parents aren’t available for testing.

Family names aren’t your family names, but the top family names that match to you. Guess what my highest name is? Smith.

However, Ancestor Birthplaces are quite useful because you can sort by country. For example, my mother’s grandfather Ferverda was born in the Netherlands.

First Steps 23andMe country.png

If I click on Netherlands, I can see my 5 matches with ancestors born in the Netherlands. Of course, this doesn’t mean that I match because of my match’s Dutch ancestors, but it does provide me with a place to look for a common ancestor and I can proceed by seeing who I match in common with those matches. Unfortunately, without trees we’re left to rely on ancestor birthplaces and family surnames, if my matches have entered that information.

One of my Dutch matches also matches my Ferverda cousin. Given that connection, and that the Ferverda family immigrated from Holland in 1868, that’s a starting point.

MyHeritage has a similar features and they are much more prevalent in Europe.

By clicking on my Ferverda cousin, I can view the DNA we share, who we match in common, our common ethnicity and more. I have the option of comparing multiple people in the chromosome browser by clicking on “View DNA Comparison” and then selecting who I wish to compare.

First Steps 23andMe view DNA Comparison.png

By scrolling down instead of clicking on View DNA Comparison, I can view where my Ferverda cousin matches me on my chromosomes, shown below.

First STeps 23andMe chromosome browser.png

23andMe identifies completely identical segments which would be painted in dark purple, the legend at bottom left.

Adoptees love this feature because it would immediately differentiate between half and full siblings. Full siblings share approximately 25% of the exact DNA on both their maternal and paternal strands of DNA, while half siblings only share the DNA from one parent – assuming their parents aren’t closely related. I share no completely identical DNA with my Ferverda cousin, so no segments are painted dark purple.

23andMe and Ancestry Maps Show Where Your Matches Live

Another reason that adoptees and people searching for birth parents or unknown relatives like 23andMe is because of the map function.

After clicking on DNA Relatives, click on the Map function at the top of the page which displays the following map.

First Steps 23andMe map

click to enlarge

This isn’t a map of where your matches ancestors lived, but is where your matches THEMSELVES live. Furthermore, you can zoom in, click on the button and it displays the name of the individual and the city where they live or whatever they entered in the location field.

First Steps 23andMe your location on map.png

I entered a location in my profile and confirmed that the location indeed displays on my match’s maps by signing on to another family member’s account. What I saw is the display above. I’d wager that most testers don’t realize that their home location and photo, if entered, is being displayed to their matches.

I think sharing my ancestors’ locations is a wonderful, helpful, idea, but there is absolutely no reason whatsoever for anyone to know where I live and I feel it’s stalker-creepy and a safety risk.

First Steps 23andMe questions.png

If you enter a location in this field in your profile, it displays on the map.

If you test with 23andMe and you don’t want your location to display on this map to your matches, don’t answer any question that asks you where you call home or anything similar. I never answer any questions at 23andMe. They are known for asking you the same question repeatedly, in multiple locations and ways, until you relent and answer.

Ancestry has a similar map feature and they’ve also begun to ask you questions that are unrelated to genealogy.

Ancestry Map Shows Where Your Matches Live

At Ancestry, when you click to see your DNA matches, look to the right at the map link.

First Steps Ancestry map link.png

By clicking on this link, you can see the locations that people have entered into their profile.

First Steps Ancestry match map.png

As you can see, above, I don’t have a location entered and I am prompted for one. Note that Ancestry does specifically say that this location will be shown to your matches.

You can click on the Ancestry Profile link here, or go to your Personal Profile by click the dropdown under your user name in the upper right hand corner of any page.

This is important because if you DON’T want your location to show, you need to be sure there is nothing entered in the location field.

Sometimes Your Answer is a Little More Complicated

This is a First Steps article. Sometimes the answer you seek might be a little more complicated. That’s why there are specialists who deal with this all day, everyday.

What issues might be more complex?

If you’re just starting out, don’t worry about these things for now. Just know when you run into something more complex or that doesn’t make sense, I’m here and so are others. Here’s a link to my Help page.

Getting Started

What do you need to get started?

  • You need to take a DNA test, or more specifically, multiple DNA tests. You can test at Ancestry or 23andMe and transfer your results to both Family Tree DNA and MyHeritage, or you can test directly at all vendors.

Neither Ancestry nor 23andMe accept uploads, meaning other vendors tests, but both MyHeritage and Family Tree DNA accept most file versions. Instructions for how to download and upload your DNA results are found below, by vendor:

Both MyHeritage and Family Tree DNA charge a minimal fee to unlock their advanced features such as chromosome browsers and ethnicity if you upload transfer files, but it’s less costly in both cases than testing directly. However, if you want the MyHeritage DNA plus Health or the Family Tree DNA Y DNA or Mitochondrial DNA tests, you must test directly at those companies for those tests.

  • It’s not required, but it would be in your best interest to build as much of a tree at all three vendors as you can. Every little bit helps.

Your first tree-building step should be to record what your family knows about your grandparents and great-grandparents, aunts and uncles. Here’s what my first step attempt looked like. It’s cringe-worthy now, but everyone has to start someplace. Just do it!

You can build a tree at either Ancestry or MyHeritage and download your tree for uploading at the other vendors. Or, you can build the tree using genealogy software on your computer and upload to all 3 places. I maintain my primary tree on my computer using RootsMagic. There are many options. MyHeritage even provides free tree builder software.

Both Ancestry and MyHeritage offer research/data subscriptions that provide you with hints to historical documents that increase what you know about your ancestors. The MyHeritage subscription can be tried for free. I have full subscriptions to both Ancestry and MyHeritage because they both include documents in their collections that the other does not.

Please be aware that document suggestions are hints and each one needs to be evaluated in the context of what you know and what’s reasonable. For example, if your ancestor was born in 1750, they are not included in the 1900 census, nor do women have children at age 70. People do have exactly the same names. FindAGrave information is entered by humans and is not always accurate. Just sayin’…

Evaluate critically and skeptically.

Ok, Let’s Go!

When your DNA results are ready, sign on to each vendor, look at your matches and use this article to begin to feel your way around. It’s exciting and the promise is immense. Feel free to share the link to this article on social media or with anyone else who might need help.

You are the cumulative product of your ancestors. What better way to get to know them than through their DNA that’s shared between you and your cousins!

2018 – The Year of the Segment

Looking in the rear view mirror, what a year! Some days it’s been hard to catch your breath things have been moving so fast.

What were the major happenings, how did they affect genetic genealogy and what’s coming in 2019?

The SNiPPY Award

First of all, I’m giving an award this year. The SNiPPY.

Yea, I know it’s kinda hokey, but it’s my way of saying a huge thank you to someone in this field who has made a remarkable contribution and that deserves special recognition.

Who will it be this year?

Drum roll…….

The 2018 SNiPPY goes to…

DNAPainter – The 2018 SNiPPY award goes to DNAPainter, without question. Applause, everyone, applause! And congratulations to Jonny Perl, pictured below at Rootstech!

Jonny Perl created this wonderful, visual tool that allows you to paint your matches with people on your chromosomes, assigning the match to specific ancestors.

I’ve written about how to use the tool  with different vendors results and have discovered many different ways to utilize the painted segments. The DNA Painter User Group is here on Facebook. I use DNAPainter EVERY SINGLE DAY to solve a wide variety of challenges.

What else has happened this year? A lot!

Ancient DNA – Academic research seldom reports on Y and mitochondrial DNA today and is firmly focused on sequencing ancient DNA. Ancient genome sequencing has only recently been developed to a state where at least some remains can be successfully sequenced, but it’s going great guns now. Take a look at Jennifer Raff’s article in Forbes that discusses ancient DNA findings in the Americas, Europe, Southeast Asia and perhaps most surprising, a first generation descendant of a Neanderthal and a Denisovan.

From Early human dispersals within the Americas by Moreno-Mayer et al, Science 07 Dec 2018

Inroads were made into deeper understanding of human migration in the Americas as well in the paper Early human dispersals within the Americas by Moreno-Mayer et al.

I look for 2019 and on into the future to hold many more revelations thanks to ancient DNA sequencing as well as using those sequences to assist in understanding the migration patterns of ancient people that eventually became us.

Barbara Rae-Venter and the Golden State Killer Case

Using techniques that adoptees use to identify their close relatives and eventually, their parents, Barbara Rae-Venter assisted law enforcement with identifying the man, Joseph DeAngelo, accused (not yet convicted) of being the Golden State Killer (GSK).

A very large congratulations to Barbara, a retired patent attorney who is also a genealogist. Nature recognized Ms. Rae-Venter as one of 2018’s 10 People Who Mattered in Science.

DNA in the News

DNA is also represented on the 2018 Nature list by Viviane Slon, a palaeogeneticist who discovered an ancient half Neanderthal, half Denisovan individual and sequenced their DNA and He JianKui, a Chinese scientist who claims to have created a gene-edited baby which has sparked widespread controversy. As of the end of the year, He Jiankui’s research activities have been suspended and he is reportedly sequestered in his apartment, under guard, although the details are far from clear.

In 2013, 23andMe patented the technology for designer babies and I removed my kit from their research program. I was concerned at the time that this technology knife could cut two ways, both for good, eliminating fatal disease-causing mutations and also for ethically questionable practices, such as eugenics. I was told at the time that my fears were unfounded, because that “couldn’t be done.” Well, 5 years later, here we are. I expect the debate about the ethics and eventual regulation of gene-editing will rage globally for years to come.

Elizabeth Warren’s DNA was also in the news when she took a DNA test in response to political challenges. I wrote about what those results meant scientifically, here. This topic became highly volatile and politicized, with everyone seeming to have a very strongly held opinion. Regardless of where you fall on that opinion spectrum (and no, please do not post political comments as they will not be approved), the topic is likely to surface again in 2019 due to the fact that Elizabeth Warren has just today announced her intention to run for President. The good news is that DNA testing will likely be discussed, sparking curiosity in some people, perhaps encouraging them to test. The bad news is that some of the discussion may be unpleasant at best, and incorrect click-bait at worst. We’ve already had a rather unpleasant sampling of this.

Law Enforcement and Genetic Genealogy

The Golden State Killer case sparked widespread controversy about using GedMatch and potentially other genetic genealogy data bases to assist in catching people who have committed violent crimes, such as rape and murder.

GedMatch, the database used for the GSK case has made it very clear in their terms and conditions that DNA matches may be used for both adoptees seeking their families and for other uses, such as law enforcement seeking matches to DNA sequenced during a criminal investigation. Since April 2018, more than 15 cold case investigations have been solved using the same technique and results at GedMatch. Initially some people removed their DNA from GedMatch, but it appears that the overwhelming sentiment, based on uploads, is that people either aren’t concerned or welcome the opportunity for their DNA matches to assist apprehending criminals.

Parabon Nanolabs in May established a genetic genealogy division headed by CeCe Moore who has worked in the adoptee community for the past several years. The division specializes in DNA testing forensic samples and then assisting law enforcement with the associated genetic genealogy.

Currently, GedMatch is the only vendor supporting the use of forensic sample matching. Neither 23anMe nor Ancestry allow uploaded data, and MyHeritage and Family Tree DNA’s terms of service currently preclude this type of use.

MyHeritage

Wow talk about coming onto the DNA world stage with a boom.

MyHeritage went from a somewhat wobbly DNA start about 2 years ago to rolling out a chromosome browser at the end of January and adding important features such as SmartMatching which matches your DNA and your family trees. Add triangulation to this mixture, along with record matching, and you’re got a #1 winning combination.

It was Gilad Japhet, the MyHeritage CEO who at Rootstech who christened 2018 “The Year of the Segment,” and I do believe he was right. Additionally, he announced that MyHeritage partnered with the adoption community by offering 15,000 free kits to adoptees.

In November, MyHeritage hosted MyHeritage LIVE, their first user conference in Oslo, Norway which focused on both their genealogical records offerings as well as DNA. This was a resounding success and I hope MyHeritage will continue to sponsor conferences and invest in DNA. You can test your DNA at MyHeritage or upload your results from other vendors (instructions here). You can follow my journey and the conference in Olso here, here, here, here and here.

GDPR

GDPR caused a lot of misery, and I’m glad the implementation is behind us, but the the ripples will be affecting everyone for years to come.

GDPR, the European Data Protection Regulation which went into effect on May 25,  2018 has been a mixed and confusing bag for genetic genealogy. I think the concept of users being in charge and understanding what is happened with their data, and in this case, their data plus their DNA, is absolutely sound. The requirements however, were created without any consideration to this industry – which is small by comparison to the Googles and Facebooks of the world. However, the Googles and Facebooks of the world along with many larger vendors seem to have skated, at least somewhat.

Other companies shut their doors or restricted their offerings in other ways, such as World Families Network and Oxford Ancestors. Vendors such as Ancestry and Family Tree DNA had to make unpopular changes in how their users interface with their software – in essence making genetic genealogy more difficult without any corresponding positive return. The potential fines, 20 million plus Euro for any company holding data for EU residents made it unwise to ignore the mandates.

In the genetic genealogy space, the shuttering of both YSearch and MitoSearch was heartbreaking, because that was the only location where you could actually compare Y STR and mitochondrial HVR1/2 results. Not everyone uploaded their results, and the sites had not been updated in a number of years, but the closure due to GDPR was still a community loss.

Today, mitoydna.org, a nonprofit comprised of genetic genealogists, is making strides in replacing that lost functionality, plus, hopefully more.

On to more positive events.

Family Tree DNA

In April, Family Tree DNA announced a new version of the Big Y test, the Big Y-500 in which at least 389 additional STR markers are included with the Big Y test, for free. If you’re lucky, you’ll receive between 389 and 439 new markers, depending on how many STR markers above 111 have quality reads. All customers are guaranteed a minimum of 500 STR markers in total. Matching was implemented in December.

These additional STR markers allow genealogists to assemble additional line marker mutations to more granularly identify specific male lineages. In other words, maybe I can finally figure out a line marker mutation that will differentiate my ancestor’s line from other sons of my founding ancestor😊

In June, Family Tree DNA announced that they had named more than 100,000 SNPs which means many haplogroup additions to the Y tree. Then, in September, Family Tree DNA published their Y haplotree, with locations, publicly for all to reference.

I was very pleased to see this development, because Family Tree DNA clearly has the largest Y database in the industry, by far, and now everyone can reap the benefits.

In October, Family Tree DNA published their mitochondrial tree publicly as well, with corresponding haplogroup locations. It’s nice that Family Tree DNA continues to be the science company.

You can test your Y DNA, mitochondrial or autosomal (Family Finder) at Family Tree DNA. They are the only vendor offering full Y and mitochondrial services complete with matching.

2018 Conferences

Of course, there are always the national conferences we’re familiar with, but more and more, online conferences are becoming available, as well as some sessions from the more traditional conferences.

I attended Rootstech in Salt Lake City in February (brrrr), which was lots of fun because I got to meet and visit with so many people including Mags Gaulden, above, who is a WikiTree volunteer and writes at Grandma’s Genes, but as a relatively expensive conference to attend, Rootstech was pretty miserable. Rootstech has reportedly made changes and I hope it’s much better for attendees in 2019. My attendance is very doubtful, although I vacillate back and forth.

On the other hand, the MyHeritage LIVE conference was amazing with both livestreamed and recorded sessions which are now available free here along with many others at Legacy Family Tree Webinars.

Family Tree University held a Virtual DNA Conference in June and those sessions, along with others, are available for subscribers to view.

The Virtual Genealogical Association was formed for those who find it difficult or impossible to participate in local associations. They too are focused on education via webinars.

Genetic Genealogy Ireland continues to provide their yearly conference sessions both livestreamed and recorded for free. These aren’t just for people with Irish genealogy. Everyone can benefit and I enjoy them immensely.

Bottom line, you can sit at home and educate yourself now. Technology is wonderful!

2019 Conferences

In 2019, I’ll be speaking at the National Genealogical Society Family History Conference, Journey of Discovery, in St. Charles, providing the Special Thursday Session titled “DNA: King Arthur’s Mighty Genetic Lightsaber” about how to use DNA to break through brick walls. I’ll also see attendees at Saturday lunch when I’ll be providing a fun session titled “Twists and Turns in the Genetic Road.” This is going to be a great conference with a wonderful lineup of speakers. Hope to see you there.

There may be more speaking engagements at conferences on my 2019 schedule, so stay tuned!

The Leeds Method

In September, Dana Leeds publicized The Leeds Method, another way of grouping your matches that clusters matches in a way that indicates your four grandparents.

I combine the Leeds method with DNAPainter. Great job Dana!

Genetic Affairs

In December, Genetic Affairs introduced an inexpensive subscription reporting and visual clustering methodology, but you can try it for free.

I love this grouping tool. I have already found connections I didn’t know existed previously. I suggest joining the Genetic Affairs User Group on Facebook.

DNAGedcom.com

I wrote an article in January about how to use the DNAGedcom.com client to download the trees of all of your matches and sort to find specific surnames or locations of their ancestors.

However, in December, DNAGedcom.com added another feature with their new DNAGedcom client just released that downloads your match information from all vendors, compiles it and then forms clusters. They have worked with Dana Leeds on this, so it’s a combination of the various methodologies discussed above. I have not worked with the new tool yet, as it has just been released, but Kitty Cooper has and writes about it here.  If you are interested in this approach, I would suggest joining the Facebook DNAGedcom User Group.

Rootsfinder

I have not had a chance to work with Rootsfinder beyond the very basics, but Rootsfinder provides genetic network displays for people that you match, as well as triangulated views. Genetic networks visualizations are great ways to discern patterns. The tool creates match or triangulation groups automatically for you.

Training videos are available at the website and you can join the Rootsfinder DNA Tools group at Facebook.

Chips and Imputation

Illumina, the chip maker that provides the DNA chips that most vendors use to test changed from the OmniExpress to the GSA chip during the past year. Older chips have been available, but won’t be forever.

The newer GSA chip is only partially compatible with the OmniExpress chip, providing limited overlap between the older and the new results. This has forced the vendors to use imputation to equalize the playing field between the chips, so to speak.

This has also caused a significant hardship for GedMatch who is now in the position of trying to match reasonably between many different chips that sometimes overlap minimally. GedMatch introduced Genesis as a sandbox beta version previously, but are now in the process of combining regular GedMatch and Genesis into one. Yes, there are problems and matching challenges. Patience is the key word as the various vendors and GedMatch adapt and improve their required migration to imputation.

DNA Central

In June Blaine Bettinger announced DNACentral, an online monthly or yearly subscription site as well as a monthly newsletter that covers news in the genetic genealogy industry.

Many educators in the industry have created seminars for DNACentral. I just finished recording “Getting the Most out of Y DNA” for Blaine.

Even though I work in this industry, I still subscribed – initially to show support for Blaine, thinking I might not get much out of the newsletter. I’m pleased to say that I was wrong. I enjoy the newsletter and will be watching sessions in the Course Library and the Monthly Webinars soon.

If you or someone you know is looking for “how to” videos for each vendor, DNACentral offers “Now What” courses for Ancestry, MyHeritage, 23andMe, Family Tree DNA and Living DNA in addition to topic specific sessions like the X chromosome, for example.

Social Media

2018 has seen a huge jump in social media usage which is both bad and good. The good news is that many new people are engaged. The bad news is that people often given faulty advice and for new people, it’s very difficult (nigh on impossible) to tell who is credible and who isn’t. I created a Help page for just this reason.

You can help with this issue by recommending subscribing to these three blogs, not just reading an article, to newbies or people seeking answers.

Always feel free to post links to my articles on any social media platform. Share, retweet, whatever it takes to get the words out!

The general genetic genealogy social media group I would recommend if I were to select only one would be Genetic Genealogy Tips and Techniques. It’s quite large but well-managed and remains positive.

I’m a member of many additional groups, several of which are vendor or interest specific.

Genetic Snakeoil

Now the bad news. Everyone had noticed the popularity of DNA testing – including shady characters.

Be careful, very VERY careful who you purchase products from and where you upload your DNA data.

If something is free, and you’re not within a well-known community, then YOU ARE THE PRODUCT. If it sounds too good to be true, it probably is. If it sounds shady or questionable, it’s probably that and more, or less.

If reputable people and vendors tell you that no, they really can’t determine your Native American tribe, for example, no other vendor can either. Just yesterday, a cousin sent me a link to a “tribe” in Canada that will, “for $50, we find one of your aboriginal ancestors and the nation stamps it.” On their list of aboriginal people we find one of my ancestors who, based on mitochondrial DNA tests, is clearly NOT aboriginal. Snake oil comes in lots of flavors with snake oil salesmen looking to prey on other people’s desires.

When considering DNA testing or transfers, make sure you fully understand the terms and conditions, where your DNA is going, who is doing what with it, and your recourse. Yes, read every single word of those terms and conditions. For more about legalities, check out Judy Russell’s blog.

Recommended Vendors

All those DNA tests look yummy-good, but in terms of vendors, I heartily recommend staying within the known credible vendors, as follows (in alphabetical order).

For genetic genealogy for ethnicity AND matching:

  • 23andMe
  • Ancestry
  • Family Tree DNA
  • GedMatch (not a vendor because they don’t test DNA, but a reputable third party)
  • MyHeritage

You can read about Which DNA Test is Best here although I need to update this article to reflect the 2018 additions by MyHeritage.

Understand that both 23andMe and Ancestry will sell your DNA if you consent and if you consent, you will not know who is using your DNA, where, or for what purposes. Neither Family Tree DNA, GedMatch, MyHeritage, Genographic Project, Insitome, Promethease nor LivingDNA sell your DNA.

The next group of vendors offers ethnicity without matching:

  • Genographic Project by National Geographic Society
  • Insitome
  • LivingDNA (currently working on matching, but not released yet)

Health (as a consumer, meaning you receive the results)

Medical (as a contributor, meaning you are contributing your DNA for research)

  • 23andMe
  • Ancestry
  • DNA.Land (not a testing vendor, doesn’t test DNA)

There are a few other niche vendors known for specific things within the genetic genealogy community, many of whom are mentioned in this article, but other than known vendors, buyer beware. If you don’t see them listed or discussed on my blog, there’s probably a reason.

What’s Coming in 2019

Just like we couldn’t have foreseen much of what happened in 2018, we don’t have access to a 2019 crystal ball, but it looks like 2019 is taking off like a rocket. We do know about a few things to look for:

  • MyHeritage is waiting to see if envelope and stamp DNA extractions are successful so that they can be added to their database.
  • www.totheletterDNA.com is extracting (attempting to) and processing DNA from stamps and envelopes for several people in the community. Hopefully they will be successful.
  • LivingDNA has been working on matching since before I met with their representative in October of 2017 in Dublin. They are now in Beta testing for a few individuals, but they have also just changed their DNA processing chip – so how that will affect things and how soon they will have matching ready to roll out the door is unknown.
  • Ancestry did a 2018 ethnicity update, integrating ethnicity more tightly with Genetic Communities, offered genetic traits and made some minor improvements this year, along with adding one questionable feature – showing your matches the location where you live as recorded in your profile. (23andMe subsequently added the same feature.) Ancestry recently said that they are promising exciting new tools for 2019, but somehow I doubt that the chromosome browser that’s been on my Christmas list for years will be forthcoming. Fingers crossed for something new and really useful. In the mean time, we can download our DNA results and upload to MyHeritage, Family Tree DNA and GedMatch for segment matching, as well as utilize Ancestry’s internal matching tools. DNA+tree matching, those green leaf shared ancestor hints, is still their strongest feature.
  • The Family Tree DNA Conference for Project Administrators will be held March 22-24 in Houston this year, and I’m hopeful that they will have new tools and announcements at that event. I’m looking forward to seeing many old friends in Houston in March.

Here’s what I know for sure about 2019 – it’s going to be an amazing year. We as a community and also as individual genealogists will be making incredible discoveries and moving the ball forward. I can hardly wait to see what quandaries I’ve solved a year from now.

What mysteries do you want to unravel?

I’d like to offer a big thank you to everyone who made 2018 wonderful and a big toast to finding lots of new ancestors and breaking down those brick walls in 2019.

Happy New Year!!!

When DNA Leads You Astray

I’m currently going through what I refer to as “the great purge.”

This occurs when you can’t stand the accumulated piles and boxes of “stuff” and the file drawers are full, so you set about throwing away and giving away. (Yes, I know you just cringed. Me too.)

The great news is that I’ve run across so much old (as in decades old) genealogy from when I first began this journey. I used to make lists of questions and a research “to do” list. I was much more organized then, but there were also fewer “squirrel moments” available online to distract me with “look here, no, over here, no, wait….”

Most of those questions on my old genealogy research lists have (thankfully) since been answered, slowly, one tiny piece of evidence at a time. Believe me, that feeling is very rewarding and while on a daily basis we may not think we’re making much progress; in the big picture – we’re slaying that dragon!

However, genealogy is also fraught with landmines. If I had NOT found the documentation before the days of DNA testing, I could easily have been led astray.

“What?”, you ask, but “DNA doesn’t lie.” No, it doesn’t, but it will sure let you kid yourself about some things.

DNA is a joker and has no problem allowing you to fool yourself and by virtue of that, others as well.

Joke’s On Me

Decades ago, Aunt Margaret told me that her grandmother’s mother was “a Rosenbalm from up on the Lee County (VA) border.”

Now, at that time, I had absolutely NO reason to doubt what she said. After all, it’s her grandmother, Margaret Claxton/Clarkson who she knew personally, who didn’t pass away until my aunt was in her teens. Plenty close enough to know who Margaret Claxton’s mother was. Right?

DNA Astray Rosenbalm

Erroneous pedigree chart. Rebecca Rosenbalm is NOT the mother of Elizabeth Claxton/Clarkson.

I filled Rebecca Rosenbalm’s name into the appropriate space on my pedigree chart, was happy and smugly smiling like a Cheshire cat, right up until I accidentally discovered that the information was just plain wrong.

Uh oh….

Time Rolls On

As records became increasingly available, both in transcribed fashion and online, Hancock County, TN death certificates eventually could be obtained, one way or another. Being a dutiful genealogist, I collected all relevant documents for my ancestors, contentedly filing them in the “well that’s done” category – that is right up until Margaret Clarkson Bolton’s death certificate stopped me dead in my tracks.

margaret clarkson bolton death

Oops

Margaret’s mother wasn’t listed as Rebecca Rosenbalm, nor Rebecca anyone. She was listed as Betsy Speaks. Or was it Spears? In our family, Betsy is short for Elizabeth.

Who the heck was Elizabeth Speaks, or Spears. This was one fine monkey wrench!

A trip to Hancock County, Tennessee was in order.

I dug through dusty deed and court records, sifted through the archives in basements and the old jail building where I just KNEW my ancestors had inhabited cells at one time or another.

Yes, my ancestor’s records really were in jail!

Records revealed that the woman in question was Elizabeth Speaks, not Spears, although the Spears family did live in the area and had “married in” to many local families. Nothing is ever simple and our ancestors do have a perverse sense of humor.

Elizabeth Speak(s) was the daughter of Charles Speak, and the Speak family lived a few miles across the border into Lee County, Virginia. This high mountain land borders two states and three counties, so records are scattered among them – not to mention two fires in the Hancock County courthouse make research challenging.

Why?

I asked my Aunt Margaret who was still living at the time about this apparent discrepancy and she told me that the Rosenbalms “up in Rose Hill, Virginia” told her that her grandmother, Margaret Claxton/Clarkson was kin to them, so Margaret had assumed (there’s that word again) that Margaret Claxton’s mother was their Rebecca Rosenbalm.

Wrong!

The Kernel of Truth

Like so many family stories, there is a kernel of truth, surrounded by a multitude errors. Distilling the grain of truth is the challenge of course.

Margaret Claxton’s mother was Elizabeth (Betsy) Speak and her father was Charles Speak. Charles Speak’s sister, Rebecca married William Henderson Rosenbalm in 1854, had 4 children and died in February 1859. So there indeed was a woman named Rebecca (Speaks) Rosenbalm who had died young and wasn’t well known.

Rebecca’s sister Frances “Fanny” Speak also married that same William Henderson Rosenbalm in November 1859, a few months after Rebecca had died. Fannie also had 4 children, one of which was also named Rebecca Rosenbalm. Do you see a trend here?

So, indeed there were 7 living Rosenbalm children who were first cousins to Elizabeth Speak who married Samuel Claxton and lived a dozen miles away, over the mountains and across the Powell River. Now a dozen miles might not sound like much today, but in the mountains during horse and wagon days – 10 miles wasn’t trivial and required a multi-day commitment for a visit. In other words, the next generation of the family knew of their cousins but didn’t know them well.

The following generation included my Aunt Margaret who was told by those cousins that she was related to them through the Rosenbalm family. While, that was true for the Rosenbalm cousins, it was not true for Aunt Margaret who was related to the Rosenbalms through their common Speak ancestor.

Here’s what the family tree really looks like, only showing the lines under discussion.

DNA astray correct pedigree

You can see why Aunt Margaret might not know specifics. She was actually several generations removed from the common ancestor. She knew THAT they were related, but not HOW they were related and there were several Rebecca’s in several branches of the family.

Why Does This Matter?

You’ve probably guessed by now that someplace in here, there’s a moral to this story, so here it is!

You may have already surmised that I have autosomal DNA matches to cousins through the Rosenbalm/Speaks line.

DNA astray pedigree match

This is one example, but there are more, some being double cousins meaning two of Nicholas Speak’s 11 children’s descendants have intermarried. Life is a lot more complex in those hills and hollers than people think – and unraveling the relationships, both paper and genetic (which are sometimes two different things) is challenging.

DNA astray chromosome 10.png

I match this fourth cousin once removed (4C1R) on a healthy 18 cM segment on chromosome 10.

Wrong Conclusions

Now, think back to where I was originally in my research. I knew that Margaret Claxton/Clarkson was my aunt’s grandmother. I knew nothing at all about the Speak family and had never heard that surname.

Had I ONLY been looking to confirm the Rosenbalm connection, I certainly would have confirmed that I’m related to the Rosenbalm family descendants with this match. Except the conclusion that I descend from a Rosenbalm ancestor would have been WRONG. What we share are the Speak ancestors.

So really, the DNA didn’t lie, but unless I dissected what the DNA match was really telling me carefully and methodically with NO PRECONCEIVED NOTIONS, I would have “confirmed” erroneous information. Or, at least I would have thought that I confirmed it.

I would actually have been doing something worse meaning convincing myself of “facts” that weren’t accurate, which means I would have then been spreading around those cancerous bad trees. Guaranteed, I do NOT want to be that person.

Foolers

I can tell you here and now that I have found several matches that were foolers because I share multiple ancestors with a person that I match, even if those multiple ancestors aren’t known to either or both of us. Every single DNA segment has its own unique history. I match one individual on two segments, one segment through my mom and one segment through my dad. Fortunately, we’ve identified both ancestors now, but imaging my initial surprise and confusion, especially given that my parents don’t share any common ancestors, communities or locations.

We have to evaluate all of the evidence to confirm that the conclusion being drawn in accurate.

DNA astray painting

One of the sanity checks I use, in addition to triangulation, is to paint my matches with known ancestors on my chromosomes using DNAPainter. Here’s the match to my cousin, and it overlaps with other people who share the same ancestor couple. Several matches are obscured behind the black box. If I discover someone that I supposedly match from a different ancestor couple sharing this segment of my father’s DNA, that’s a red neon flashing sign that something is wrong and I need to figure out what and why.

Ignoring this problem and hoping it will go away doesn’t work. I’ve tried😊

Three possible things can be wrong:

  1. The segment is identical by chance, not by descent. With a segment of 18 cM, that’s extremely unlikely. Triangulation with other people on this same segment on the same parent’s side should eliminate most false matches over 7cM. The larger the match, the more likely it is NOT identical by chance, meaning that it IS identical by descent or genealogically relevant.
  2. The segment is accurately matched but the genealogy is confused – such as my Rosenbalm example. This can happen with multiple ancestors, or descent from the same family but through an unknown connection. Looking for other connections to this family and sorting through matches’ trees often provides hints that resolve this situation. In my case, I might have noticed that I matched other people who descended from Nicholas Speak, which would not have been the case had I descended through the Rosenbalm family.
  3. The third scenarios is that the genealogy is plain flat out wrong. Yea, I know this one hurts. Get the saw ready.

The Devil in the Details

Always evaluate your matches in light of what you don’t know, not in order to confirm what you think you know. Play the devil’s advocate – all the time. After all, the devil really is in the details.

MyHeritage LIVE Conference Day 2 – The Science Behind DNA Matching    

The MyHeritage LIVE Oslo conference is but a fond memory now, and I would count it as a resounding success.

Perhaps one of the reasons I enjoyed it so much is the scientific aspect and because the content is very focused on a topic I enjoy without being the size and complexity of Rootstech. The smaller, more intimate venue also provides access to the “right” people as well as the ability to meet other attendees and not be overwhelmed by the sheer size.

Here are some stats:

  • 401 registered guests
  • 28 countries represented including distant places like Australia and South America
  • More than 20 speakers plus the hands-on workshops where specialist teams worked with students
  • 38 sessions and workshops, plus the party
  • 60,000 livestream participants, in spite of the time differences around the world

I was blown away by the number of livestream attendees.

I don’t know what criteria Gilad Japhet will be using to determine “success” but I can’t imagine this conference being judged as anything but.

Let’s take a look at the second day. I spent part of the time talking to people and drifting in and out of the rear of several sessions for a few minutes. I meant to visit some of the workshops, but there was just too much good, distracting content elsewhere.

I began Sunday in Mike Mansfield’s presentation about SuperSearch. Yes, I really did attend a few sessions not about DNA, but my favorite was the session on Improved DNA Matching.

Improved DNA Matching

I’m sure it won’t surprise any of my readers that my favorite presentations were about the actual science of genetic genealogy.

Consumers don’t really need to understand the science behind autosomal results to reap the benefits, but the underlying science is part of what I love – and it’s important for me to understand the underpinnings to be able to unravel the fine points of what the resulting matches are and are not revealing. Misinterpretation of DNA results leading to faulty conclusions is a real issue in genetic genealogy today. Consequently, I feel that anyone working with other people’s results and providing advice really needs to understand how the science and technology together works.

Dr. Daphna Weissglas-Volkov, a population geneticist by training, although she clearly functions far beyond that scope today, gave a very interesting presentation about how MyHeritage handles (their greatly improved) DNA Matching. I’m hitting the high points here, but I would strongly encourage you to watch the video of this session when they are made available online.

In addition to Dr. Weissglas-Volkov’s slides, I’ve added some additional explanations and examples in various places. You can easily tell that the slides are hers and the graphics that aren’t MyHeritage slides are mine.

Dr. Weissglas-Volkov began the session by introducing the MyHeritage science team and then explaining terminology to set the stage.

A match is when two people match each other on a fairly long piece of DNA. Of course, “fairly long” is defined differently by each vendor.

Your genetic map (of your chromosomes) is comprised of the DNA you inherit from different ancestors by the process of recombination when DNA is transferred from the parents to the child. A centiMorgan is the relatively likelihood that a recombination will occur in a single generation. On average, 36 recombinations occur in each generation, meaning that the DNA is divided on any chromosome. However, women, for reasons unknown have about 1.5 times as many recombinations as men.

You can’t see that when looking at an example of a person compared to their parents, of course, because each individual is a full match to each parent, but you can see this visually when comparing a grandchild to their maternal grandmother and their paternal grandmother on a chromosome browser.

The above illustration is the same female grandchild compared to her maternal grandmother, at left, and her paternal grandmother at right. Therefore the number of crossovers at left is through a female child (her mother), and the number at right is through a male child (her father.)

# of Crossovers
Through female child – left 57
Through male child – right 22

There are more segments at left, through the mother, and the segments are generally shorter, because they have been divided into more pieces.

At right, fewer and larger segments through the father.

Keep in mind that because you have a strand of DNA from each parent, with exactly the same “street addresses,” that what is produced by DNA sequencing are two columns of data – but your Mom’s and Dad’s DNA is intermixed.

The information in the two columns can’t be identified as Mom’s or Dad’s DNA or strand at this point.

That interspersed raw data is called a genotype. A haplotype is when Mom’s and Dad’s DNA can be reassembled into “sides” so you can attribute the two letters at each address to either Mom or Dad.

Here’s a quick example.

The goal, of course, is to figure out how to reassemble your DNA into Mom’s side and Dad’s side so that we know that someone matching you is actually matching on all As (Mom) or all Gs (Dad,) in this example, and not a false match that zigzags back and forth between Mom and Dad.

The best way to accomplish that goal of course is trio phasing, when the child and both parents are available, so by comparing the child’s DNA with the parents you can assign the two strands of the child’s DNA.

Unfortunately, few people have both or even one parent available in order to actual divide their DNA into “sides,” so the next best avenue is statistical phasing. I’ve called this academic phasing in the past, as compared to parental phasing which MyHeritage refers to as trio phasing.

There’s a huge amount of confusion about phasing, with few people understanding there are two distinct types.

Statistical phasing is a type of machine learning where a large number of reference populations are studied. Since we know that DNA travels together in blocks when inherited, statistical phasing learns which DNA travels with which buddy DNA – and creates probabilities. Your DNA is then compared to these models and your DNA is reshuffled in order to assemble your DNA into two groups – one representing your Mom’s DNA and one representing your Dad’s DNA, according to statistical probability.

Looking at your genotype, if we know that As group together at those 6 addresses in my example 95% of the time, then we know that the most likely scenario to create a haplotype is that all of the As came from one parent and all of the Gs from the other parent – although without additional information, there is no way to yet assign the maternal and paternal identifier. At this point, we only know parent 1 and parent 2.

In order to train the computers (machine learning) to properly statistically phase testers’ results, MyHeritage uses known relationships of people to teach the machines. In other words, their reference panels of proven haplotypes grows all of the time as parent/child trios test.

Dr. Weissglas-Volkev then moved on to imputation.

When sequencing DNA, not every location reads accurately, so the missing values can be imputed, or “put back” using imputation.

Initially imputation was a hot mess. Not just for MyHeritage, but for all vendors, imputation having been forced upon them (and therefore us) by Illumina’s change to the GSA chip.

However, machine learning means that imputation models improve constantly, and matching using imputation is greatly improved at MyHeritage today.

Imputation can do more than just fill in blanks left by sequencing read errors.

The benefit of imputation to the genetic genealogy community is that vendors using disparate chips has forced vendors that want to allow uploads to utilize imputation to create a global template that incorporates all of the locations from each vendor, then impute the values they don’t actually test for themselves to complete the full template for each person.

In the example below, you can see that no vendor tests all available locations, but when imputation extends the sequences of all testers to the full 1-500 locations, the results can easily be compared to every other tester because every tester now has values in locations 1-500, regardless of which vendor/chip was utilized in their actual testing.

Therefore, using imputation, MyHeritage is able to match between quite disparate chips, such as the traditional Illumina chips (OmniExpress), the custom Ancestry chip and the new GSA chip utilized by 23andMe and LivingDNA.

So, how are matches determined?

Matching

First your DNA and that of another person are scanned for nearly identical seed sequences.

A minimum segment length of 6cM must be identified for further match processing to occur. Anything below 6cM is discarded at this point.

The match is then further evaluated to see if the seed match is of a high enough quality that it should be perfected and should count as a match. Other segments continue to be evaluated as well. If the total matching segment(s) is 8 total cM or greater, it’s considered a valid match. MyHeritage has taken the position that they would rather give you a few accidental false matches than to miss good matches. I appreciate that position.

Window cleaning is how they refer to the process of removing pileup regions known to occur in the human genome. This is NOT the same as Ancestry’s routine that removes areas they determine to be “too matchy” for you individually.

The difference is that in humans, for example, there is a segment of chromosome 6 where, for some reason, almost all humans match. Matching across that segment is not informative for genetic genealogy, so that region along with several others similar in nature are removed. At Ancestry, those genome-wide pileup segments are removed, along with other regions where Ancestry decides that you personally have too many matches. The problem is that for me, these “too matchy” segments are many of my Acadian matches. Acadians are endogamous, so lots of them match each other because as a small intermarried population, they share a great deal of the same DNA. However, to me, because I have one great-grandfather that’s Acadian, that “too matchy” information IS valuable although I understand that it wouldn’t be for someone that is 100% Acadian or Jewish.

In situations such as Ashkenazi Jewish matching, which is highly endogamous, MyHeritage uses a higher matching threshold. Otherwise every Ashkenazi person would match every other Ashkenazi person because they all descend from a small founder population, and for genealogy, that’s not useful.

The last step in processing matches is to establish the confidence level that the match is accurately predicted at the correct level – meaning the relationship range based on the amount of matching DNA and other criteria.

For example, does this match cluster with other proven matches of the same known relationship level?

From several confidence ascertainment steps, a confidence score is assigned to the predicted relationship.

Of course, you as a customer see none of this background processing, just the fact that you do match, the size of the match and the confidence score. That’s what genealogists need!

Matching Versus Triangulation Thresholds

Confusion exists about matching thresholds versus triangulation thresholds.

While any single segment must be over 6 cM in length for the matching process to begin, the actual match threshold at MyHeritage is a total of 8 cM.

I took a look at my lowest match at MyHeritage.

I have two segments, one 6.1 cM segment, and one 6 cM segment that match. It would appear that if I only had one 6 cM segment, it would not show as a match because I didn’t have the minimum 8 cM total.

Triangulation Threshold

However, after you pass that matching criteria and move on to triangulation with a matching individual, you have the option of selecting the triangulation threshold, which is not the same thing as the match threshold. The match threshold does not change, but you can change the triangulation threshold from 2 cM to 8 cM and selections in-between.

In the example below, I’m comparing myself against two known relatives.

You won’t be shown any matches below the 6 cM individual segment threshold, BUT you can view triangulated segments of different sizes. This is because matching segments often don’t line up exactly and the triangulated overlap between several individuals may be very small, but may still be useful information.

Flying your mouse over the location in the bubble, which is the triangulated segment, tells you the size of the triangulated portion. If you selected the 2 cM triangulation, you would see smaller triangulated portions of matches.

Closing Session

The conference was closed by Aaron Godfrey, a super-nice MyHeritage employee from the UK. The closing session is worth watching on the recorded livestream when it becomes available, in part because there are feel good moments.

However, the piece of information I was looking for was whether there will be a MyHeritage LIVE conference in 2019, and if so, where.

I asked Gilad afterwards and he said that they will be evaluating the feedback from attendees and others when making that decision.

So, if you attended or joined the livestream sessions and found value, please let MyHeritage know so that they can factor your feedback onto their decision. If there are topics you’d like to see as sessions, I’m sure they’d love to hear about that too. Me, I’m always voting for more DNA😊

I hope to hear about MyHeritage LIVE 2019, and I’m voting for any of the following locations:

  • Australia
  • New Zealand
  • Israel
  • Germany

Family Tree DNA’s New Chromosome Browser

Family Tree DNA has released their new, updated chromosome browser with a completely new look and feel. It’s quite different from the previous version, so let’s take a test drive.

The first thing you notice is a new link on your personal page in the Family Finder section.

You can access the chromosome browser in one of two ways.

  • Matches button
  • Clicking on the Chromosome Browser button

Either way, you eventually get to the same place.

Matches

By viewing your matches, you can now select a total of 7 people, increased from 5 previously, to compare to you in the chromosome browser.

After selecting the people you want to view in the chromosome browser, click on the Chromosome Brower button above your matches, just like before.

Note that on your Matches page, the other tools, such as In Common With (ICW), Not In Common With (NICW), Search by name, Search by ancestral surname, the list of ancestral surnames for each match and other information is exactly where it has always been located. Nothing else changed on the Match page except your ability to select 7 people instead of just 5.

The Chromosome Browser

The new chromosome browser tool looks different. A lot different. It’s also much more intuitive.

If you make match selections on your match page and click the chromosome browser button, you see the following page reflecting your choices. The link no longer immediately compares the individuals in the chromosome browser.

Your match list is shown to the right of the selected individuals, shown at left.

This is also the page where you land if you click the Chromosome Browser button on your dashboard.

From Your Dashboard

If you don’t click on your Matches button first, and click directly on the Chromosome Browser button, this is what you’ll see.

Your matches are shown at right, and when you select them, they will appear on the list at left.

Select as many as 7. You’ll see them appear to the left as you make your selections.

Features

To aid in your selection, you can utilize the filter above the matches to view only specific levels of matches.

The “name search,” at upper right, searches for an individual match with that first or last name.

However, if you enter the full name, it finds that individual person, so if you know you want to compare Uncle Rex Doe’s kit, you just search for his name as Rex, Doe or Rex Doe.

This page does NOT search the ancestral surnames. If you want to do that, you need to work from the matches page which does search for people with that ancestral surname in their Ancestral Surname List.

I’m very glad to see this new search feature for matches at the browser level. It makes searching for a particular match a LOT easier.

Notice that not all of the match information is available on this page. X matching, match date, linked relationships and ancestral surnames are only available on the Matches page.

The icons for contacting matches, notes and the tree are also only available on the Matches page.

However, a new field is available here, the number of shared segments. This number includes segments to the 1cM level so long as they are 500 SNPs or larger. For most (nonresearch) purposes, I generally use segments of 7cM or larger, although I do sometimes want to see smaller segments.

At right, the In Common With and Not In Common With functions are available by clicking on the three dots:

In Common With and Not In Common With

The In Common With (ICW) and Not In Common With (NICW) features have been greatly improved.

By selecting an individual, such as William Sterling Estes in this example, then clicking the In Common With (ICW) link, I see all of the people I match in common with William Sterling Estes. Furthermore, the system now automatically puts William Sterling Estes into my match list. By making additional selections from that ICW list and adding them to the list, I can then easily compare my DNA, that of William Sterling Estes and the people that we both match to determine if we have common matching chromosome segments.

The Not In Common With feature works exactly the same way.

Compare

To view the new chromosome browser, click on the orange compare button at the bottom of the list. It’s so large you can’t miss it!

Chromosome Browser Format

The new chromosome browser itself looks a LOT different. To begin with, the color and design of the chromosomes themselves has changed. There is now space for 7 people in the comparison on each chromosome, plus you as the “background” person that those 7 are being compared to.

Chromosomes 1-5 with 7 matches being compared to me are shown below. At the top of the page, the colors of the segments are coded by the colors at the top of the profile placards of the matches I selected.

You can view information about any individual by clicking on their profile button.

By clicking on the Update Selected Matches button, at right above the chromosomes, you can change the individuals being compared.

Now, let’s take a look at how to interpret these matches.

Reading the Results

As before, the centromere is notated by the little white “waists” in each chromosome, and the light grey represents regions not tested, so you won’t see matches there.

Please note that you can click any image to enlarge.

Notice Charlene, the navy blue person match on my chromosome 1.

Reading left to right, we have:

  • At the beginning of the chromosome, dark grey tested region with no match
  • Beginning with the red box, navy blue match region
  • Light grey untested region, crossing centromere and continuing until small navy blue region
  • The entire small tested region is navy blue, indicating a match
  • Small light grey untested region
  • Dark grey tested region that does not match
  • Navy blue region that does match to the end of the red box
  • Dark grey tested region that does not match to the end of the chromosome

We would read this as 2 matching segments, not 3, with the first large navy segment and the tiny middle navy segment forming one contiguous segment across the centromere and untested regions. The third navy part of that chromosome is a separate matching segment, because it’s separated from the first two by a darker grey area that is tested but does not match.

By positioning your cursor over the colored portions of the chromosome, and waiting for a second or so, the information about that specific segment will appear.

Please note that you can click to enlarge any graphic.

Downloading Just These Matching Segments

Clicking on Download Segments, the blue link at right just above chromosome 1 downloads just the information in a csv file for the people currently being compared in the browser. It does not download all of your matches. That feature is elsewhere.

Options

The default minimum centiMorgans display view is still 5, and you can select 1, 5, 7 or 10. All matches displayed are 500 SNPs or larger.

Detailed Segment Data

Another new feature is the Detailed Segment Data tab. Click to view.

In essence, this is the same information as the csv download file, except you don’t have to download the file and you don’t have to know anything about Excel. However, you can’t sort this data by chromosome like you can in a spreadsheet.

You can select which DNA match you wish to view, one by one.

I hope that Family Tree DNA will add the feature of being able to sort each column.

Downloading All Matches

For those interested in downloading all matches, not just the matches displayed, you can perform that function at the bottom of your matches page:

Or at the bottom of the initial Chromosome Browser selection page, but BEFORE you click on compare.

Quick Reference Feature Navigation Chart

I’m always grateful for new features and updates, but sometimes new features feel a bit like someone rearranged the furniture in the room while you were sleeping. I’ve created a quick reference chart to show you what’s available where and to help you navigate.

Summary

I like the updated chromosome browser as well as the new In Common With feature. The new browser facilitates 7 comparisons at once and is a LOT more user friend with new ease-of-use features. The new ICW page eliminates several steps and confusion that exists when trying to use the function from the Matches page.

I’m hoping that this update is a new skin in preparation for more nifty new features, such as triangulation. Hint, hint, Family Tree DNA. Christmas is coming😊

MyHeritage Rolls Out Chromosome Browser and Other Features

Recently, MyHeritage rolled out a major update of their DNA software as well as new features, including:

  • Improved Matching
  • Chromosome Browser
  • SmartMatching
  • Ancestral Surnames
  • Shared DNA Matches
  • Shared Ethnicity

You can read their blog posting here.

Additionally, they announced that they have over 1 million people in their data base now, with only 20% being transfers.

Let’s take a look at the improvements.

Note: On 2-8-2018 I updated this article where indicated.

Improved Matching

MyHeritage got off to an incredibly rocky start with their matching algorithm. You can read about their earlier problems here and here.

My most recent check in my account showed less than 100 matches and many were very inaccurate – by orders of magnitude – in both directions. People I knew that I matched elsewhere, I didn’t match at MyHeritage, and people I didn’t match elsewhere, I did match at MyHeritage.

In the first example I checked initially, MyHeritage showed me matching 8 times as much DNA as did at another vendor to the same match. In other words, 8 cM at the other vendor and 64 cM at MyHeritage. Of course, incorrect matching also leads to incorrect relationship suggestions. Clearly something was very wrong.

MyHeritage definitely needed an overhaul and it looks like that’s exactly what they did. Are their changes all improvements? I’d say yes, for the most part, but some inaccuracies still exist along with a few frustrations. They are still actively making improvements.

For example, my match who went from 8 cM elsewhere to 64 cM at MyHeritage previously is now gone altogether at MyHeritage. It would be nice if there was an indicator at MyHeritage of where your match originally tested (if they are a transfer kit) so you could easily compare, but alas, there isn’t.

Let’s take a look at the changes.

More Matches

The first thing I noticed is that I have substantially more matches.

Truthfully, I hadn’t been keeping track because their matching was so awful that it didn’t matter. However, given that I had few in late 2017, less than 100, and I now have almost 3300, I’d say it’s certainly possible that my matches increased tenfold.

Of course, results for kits sold during the holidays are being delivered now, so helps bump match numbers too.

Match Quality Comparison

The person who tested at both Family Tree DNA and MyHeritage that matches me most closely in both places is Bonnie, a proven third cousin once removed.

Estimated Relationship Total cM Longest Block Segments
Family Tree DNA 2nd-4th cousin 69 31 3 (includes X)
MyHeritage 3rd-5th cousin 52.5 30.5 2 (X not reported)

At Family Tree DNA, the X chromosome match is not included in the total cM, but is included in the matching.

The X is not included at all in matching at MyHeritage, which removes the ability to use the distinctive pattern of X matching.

Comparing my match with Bonnie, both vendors report matches on the same chromosomes, other than the X. While the cM amounts are quite similar, the total SNPs are widely divergent with the SNPs at MyHeritage being roughly 4-5 times higher than at Family Tree DNA.

FTDNA cM MH cM FTDNA SNPs MH SNPs
Chromosome 13 22.16 22.08 2574 13,440
Chromosome 16 31.02 30.48 2469 9,600
X Chromosome 49.3 Not reported 1776 Not reported

In case you’re thinking I made a transcription error on the SNPs above, which are dramatically different between vendors, I really didn’t.  I checked three times to be sure.

The MyHeritage values for chromosome 13, above, with the Family Tree DNA table for the same chromosome segment at the bottom, below.

Comparing my chromosome 13 to my parent (below) shows a total SNP count on chromosome 13 of 27,967 SNPs on the entire chromosome, so there is no way that the MyHeritage segment is roughly half of that total.

Based on this information, I would unquestionably view the MyHeritage SNP count as inaccurate. I wonder if this is a result of imputation. Even though we both have results at Family Tree DNA, I have no way of knowing if my match transferred her FTDNA kit (as I did) or if MyHeritage is imputing portions of our matching segments because she transferred a kit from elsewhere. Still, I would not expect the quadrupling of SNP values to be a result of an imputed match when the cMs seem to be quite accurate.

Update: MyHeritage says this discrepancy is the result of imputation, and that this is actually the accurate count.  I compared this same segment at GedMatch with the same results as with Family Tree DNA above.  At the current time, simply be aware that SNP county between vendors that include MyHeritage may be quite different.

Viewing Data

Let’s take a look at viewing more information about my match with Bonnie. There’s a lot more to see. 

Please note that Bonnie is a SmartMatch, but this information takes a few second to fill after the page loads, so it’s easy to bypass a SmartMatch by scrolling past it before the page finishes loading. I’m referring to a delay of 10-15 seconds or more. You can see the example below with the View Smart Matches link and the screenshot above without that link for the same match.

Unfortunately, I’ve discovered that in some cases, the same page fails to show the SmartMatches entirely, so this useful feature is not consistent:(

I was paging through my matches one page at a time looking for SmartMatches, but I finally gave up at about page 300 (of 347 pages total) when I realized I was probably missing many due to the page loading issues. Perhaps they can improve this in time. This problem combined with the inability to sort for only kits with SmartMatches makes this really nice feature terribly frustrating, consuming unnecessary hours.

Update:  On the MyHeritage DNA Results page, to the right of the search box, you will see a little upside-down key looking thing.  It’s supposed to be a funnel representing a filter.  If you click on it, you will discover that you can filter by people who have trees, shared surnames or SmartMatches. Hurray!!!

To view detailed information about a match, click on the pink “Review DNA Match” on the lower right hand corner of your match list. Don’t bother clicking on “view tree” here, because you’ll see their tree in a much-preferred pedigree view when you’re reviewing their DNA information. It’s nice to see the number of people in Bonnie’s tree.

Contact

There has been some discrepancy about whether people who do not have subscriptions can contact their matches. If you have had issues in the past, try again. In a blog article published yesterday, MyHeritage indicates that contacting matches is now free.

Smart Matches

Scrolling down, the next section of my DNA match with Bonnie is called “Smart Matches.” This is quite interesting, because it shows me common individuals in our trees. Please note that THIS DOES NOT MEAN THEY ARE ANCESTORS IN YOUR TREES. In other words, if those people are in your trees and are not your ancestors, they will show in the Smart Matches.

One of my very LEAST FAVORITE things about MyHeritage is that they list women by their husband’s surnames. It’s really quite confusing, so keep that in mind when you’re trying to decipher the SmartMatching.

Update:  You can control how married versus birth surnames are shown in your tree, but needless to say, you can’t control other people’s settings.

Individuals in my tree are shown at left and individuals in Bonnie’s tree are shown at right. It’s interesting that they refer to Bonnie as “he” and “his,” given the female avatar, which suggests that someone someplace entered a gender incorrectly perhaps.

Click on “Review Smart Match” in the bottom right corner, which displays additional information.

At the end of the comparison section, MyHeritage shows you both trees and you can accept or reject the match as the same family.

If you accept the match, MyHeritage then gives you the option of extracting data from your matches’ tree into your tree. I never, EVER do this. This is exactly how undocumented misinformation is spread like wildfire through copy/paste trees and unverified information. Now, if I had the opportunity to review any attached documents or records first…then maybe – but that’s not how this feature works today.

Ancestral Surnames

Scrolling down, the next section is ancestral surnames, as extracted from both trees.

However, it seems there’s a bug here too, because I clearly DO have a tree, as proven by the fact that SmartMatching found ancestors in both trees. SmartMatching can’t happen without both people having a tree.

Update:  I uploaded my tree long ago, and somehow during that process, I got deleted from the tree.  Given that I’m the home person, that caused this glitch, which is now fixed.

Unfortunately, MyHeritage prompted me to build a tree, and when I declined, they added a second tree for me anyway with only my node. Some things are just “too helpful” like having a 2 year old in the kitchen!

Shared DNA Matches

Keep scrolling down to see Shared DNA Matches. This section is quite interesting, because it shows a third person who matches both you and your match. In this case, the person matches both me and Bonnie.

The information at left is how Wilma matches me and the information at right is how Wilma matches Bonnie. What this doesn’t tell me is:

  • If Wilma, Bonnie and I match on a common segment
  • If Wilma, Bonnie and I share a common ancestor in our tree

I can find out both of the above items by looking at my match to Wilma to see if I match her on the same segment where I match Bonnie and by looking at Wilma’s tree, if she has one. What I can’t determine is whether or not Wilma and Bonnie match on the same segment, so this isn’t triangulation, but it’s still a great feature.

Pedigree Chart

Keep scrolling past all of the shared matches to the pedigree chart.

Your pedigree chart will be shown on one tab. Again, mine is missing. However, the tab I’m the most interested in is Bonnie’s pedigree chart. Sure enough, there’s our common ancestral couple.

The great news is that this displays 5 generations in pedigree view.  The really bad news is that if your common ancestor is more than 5 generations back, you can’t see the balance of their tree in pedigree view.  You must go back to the “view tree” option which only shows the tree in “family view” and it often looks like a big spaghetti mess, leaving the viewer unable to determine how the person searched for connects with the tester or home person in tree.  Breadcrumbs or a solid line or something, anything, would be nice! Maybe next version.

Be sure to check your tree settings and permissions at MyHeritage, because one of the options is to allow others, as in all others, to modify your tree. I would strongly recommend against this feature given that there is no ability to restrict this access to specific people.

Update:  MyHeritage indicates that this is not exactly the case and that they are have rephrased their verbiage surrounding these settings as follows:

* You and family site members whom you invited (recommended)
* You and family site managers whom you invited and nominated
* Only you

You can also grant permission for others to download your tree.

Shared Ethnicities

Keep scrolling. Next, you’ll find the shared ethnicities between Bonnie and me.

If you’re wondering about my South American Amazonian ancestors – well, so am I. I do have proven Native American from Canada. MyHeritage has said that they will be doing an ethnicity update sometime in the future. Still, at least MyHeritage did find my Native segments.

Chromosome Browser

Last, but not least, scroll once again to see your matches’ DNA matched with yours on a chromosome browser.

Fly over the pink segments to view the information about that segment, keeping in mind that the number of SNPs may be highly inflated.

Missing Features and Other Considerations

MyHeritage has made much-needed improvements and added some great features, but some functions are still missing:

  • No ability to download matches and match information – this is a significant hindrance. Update: MyHeritage indicates this is coming.
  • Chromosome browser does not support multiple comparisons – just one person at a time, but yesterday MyHeritage announced this feature is coming shortly.
  • No triangulation, but coming shortly.
  • SmartMatch notification does not load consistently or quickly, causing many SmartMatches to be missed. Update: Since you can filter by SmartMatches, this is less important.
  • Cannot select the page for viewing matches.  This means that if you are on page 100 and you get disconnected from the internet, you can’t just start viewing again at page 100 without clicking through the earlier pages.
  • No way to indicate that you’ve “dealt with” a match.  A checkbox or some type of icon would be very nice.
  • Cannot select pedigree view in their trees.  Horribly frustrating.
  • Some features are buggy, as noted in the article.
  • SNPs are inaccurate (increased 4 to 5 times.) Update: MyHeritage is checking on this but believes they are a result of imputation and are accurate.
  • No X matching
  • No ethnicity painting
  • No parental phasing (attributing matches to parental sides with or without parents having tested.)

As long as I’m making a wish list, I’d also like to search by ancestor for matches. I know that sounds somewhat backwards, but it would help me answer the question of whether or not anyone who has that same ancestor in their tree matches me. I wouldn’t categorize this as missing functionality, because no one else has this feature either.

Given where MyHeritage was a year ago, they’ve really made substantial improvements in their DNA product offering and added a chromosome browser along with other features. I really like the concept of SmartMatching that shows common tree matches with my DNA matches although I would really like for this feature to only show direct line ancestors, not every common person in our trees.

Of course, SmartMatching doesn’t automatically mean the common tree ancestor IS THE ancestor that the matching DNA segment descended from, but it’s a wonderful piece of information and points my research in that direction. Other people with the same ancestor matching on the same segment (especially if they triangulate) adds weight to that evidence.

Yesterday, in a webinar that I have not yet had the opportunity to view in its entirety, MyHeritage announced that they will add the ability to match multiple people in the chromosome browser in addition to triangulation.  You can view the 90 minute webinar for free here.

Triangulation combined with SmartMatching of ancestors would be an extremely powerful tool.

As with any company that you test with or upload your DNA data to, be sure to fully read and understand ALL OF the terms and conditions, including any privacy policy and settings. Be aware that MyHeritage is an Israeli company and is not bound by either US or EU laws in the same way that companies who are headquartered in those locations are bound. I’m not saying that this is either bad or good, just that it’s different than the other primary vendors.

Transfers

MyHeritage and Family Tree DNA are the two DNA testing vendors that provide free autosomal matches, other than GedMatch who is not a testing vendor but also provides free matching.  You can read more in the article Autosomal DNA Transfers – Which Companies Accept Which Tests?

If you’re not fishing in all 3 of those ponds by transferring your DNA results, now might be a good time to transfer. You just never know which relative you might catch!

2017 – The Year of DNA

Every year for the past 17 years has been the year of DNA for me, but for many millions, 2017 has been the year of DNA. DNA testing has become a phenomenon in its own right.

It was in 2013 that Spencer Wells predicted that 2014 would be the “year of infection.” Spencer was right and in 2014 DNA joined the ranks of household words. I saw DNA in ads that year, for the first time, not related to DNA testing or health as in, “It’s in our DNA.”

In 2014, it seemed like most people had heard of DNA, even if they weren’t all testing yet. John Q. Public was becoming comfortable with DNA.

In 2017 – DNA Is Mainstream  

If you’re a genealogist, you certainly know about DNA testing, and you’re behind the times if you haven’t tested.  DNA testing is now an expected tool for genealogists, and part of a comprehensive proof statement that meets the genealogical proof standard which includes “a reasonably exhaustive search.”  If you haven’t applied DNA, you haven’t done a reasonably exhaustive search.

A paper trail is no longer sufficient alone.

When I used to speak to genealogy groups about DNA testing, back in the dark ages, in the early 2000s, and I asked how many had tested, a few would raise their hands – on a good day.

In October, when I asked that same question in Ireland, more than half the room raised their hand – and I hope the other half went right out and purchased DNA test kits!

Consequently, because the rabid genealogical market is now pretty much saturated, the DNA testing companies needed to find a way to attract new customers, and they have.

2017 – The Year of Ethnicity

I’m not positive that the methodology some of the major companies utilized to attract new consumers is ideal, but nonetheless, advertising has attracted many new people to genetic genealogy through ethnicity testing.

If you’re a seasoned genetic genealogist, I know for sure that you’re groaning now, because the questions that are asked by disappointed testers AFTER the results come back and aren’t what people expected find their way to the forums that genetic genealogists peruse daily.

I wish those testers would have searched out those forums, or read my comparative article about ethnicity tests and which one is “best” before they tested.

More ethnicity results are available from vendors and third parties alike – just about every place you look it seems.  It appears that lots of folks think ethnicity testing is a shortcut to instant genealogy. Spit, mail, wait and voila – but there is no shortcut.  Since most people don’t realize that until after they test, ethnicity testing is becoming ever more popular with more vendors emerging.

In the spring, LivingDNA began delivering ethnicity results and a few months later, MyHeritage as well.  Ethnicity is hot and companies are seizing a revenue opportunity.

Now, the good news is that perhaps some of these new ethnicity testers can be converted into genealogists.  We just have to view ethnicity testing as tempting bait, or hopefully, a gateway drug…

2017 – The Year of Explosive Growth

DNA testing has become that snowball rolling downhill that morphed into an avalanche.  More people are seeing commercials, more people are testing, and people are talking to friends and co-workers at the water cooler who decide to test. I passed a table of diners in Germany in July to overhear, in English, discussion about ethnicity-focused DNA testing.

If you haven’t heard of DTC, direct to consumer, DNA testing, you’re living under a rock or maybe in a third world country without either internet or TV.

Most of the genetic genealogy companies are fairly closed-lipped about their data base size of DNA testers, but Ancestry isn’t.  They have gone from about 2 million near the end of 2016 to 5 million in August 2017 to at least 7 million now.  They haven’t said for sure, but extrapolating from what they have said, I feel safe with 7 million as a LOW estimate and possibly as many as 10 million following the holiday sales.

Advertising obviously pays off.

MyHeritage recently announced that their data base has reached 1 million, with only about 20% of those being transfers.

Based on the industry rumble, I suspect that the other DNA testing companies have had banner years as well.

The good news is that all of these new testers means that anyone who has tested at any of the major vendors is going to get lots of matches soon. Santa, it seems, has heard about DNA testing too and test kits fit into stockings!

That’s even better news for all of us who are in multiple data bases – and even more reason to test at all of the 4 major companies who provide autosomal DNA matching for their customers: Family Tree DNA, Ancestry, MyHeritage and 23andMe.

2017 – The Year of Vendor and Industry Churn

So much happened in 2017, it’s difficult to keep up.

  • MyHeritage entered the DNA testing arena and began matching in September of 2016. Frankly, they had a mess, but they have been working in 2017 to improve the situation.  Let’s just say they still have some work to do, but at least they acknowledge that and are making progress.
  • MyHeritage has a rather extensive user base in Europe. Because of their European draw, their records collections and the ability to transfer results into their data base, they have become the 4th vendor in a field that used to be 3.
  • In March 2017, Family Tree DNA announced that they were accepting transfers of both the Ancestry V2 test, in place since May of 2016, along with the 23andMe V4 test, available since November 2013, for free. MyHeritage has since been added to that list. The Family Tree DNA announcement provided testers with another avenue for matching and advanced tools.
  • Illumina obsoleted their OmniExpress chip, forcing vendors to Illumina’s new GSA chip which also forces vendors to use imputation. I swear, imputation is a swear word. Illumina gets the lump of coal award for 2017.
  • I wrote about imputation here, but in a nutshell, the vendors are now being forced to test only about 20% of the DNA locations available on the previous Illumina chip, and impute or infer using statistics the values in the rest of the DNA locations that they previously could test.
  • Early imputation implementers include LivingDNA (ethnicity only), MyHeritage (to equalize the locations of various vendor’s different chips), DNA.Land (whose matching is far from ideal) and 23andMe, who seems, for the most part, to have done a reasonable job. Of course, the only way to tell for sure at 23andMe is to test again on the V5 chip and compare to V3 and V4 chip matches. Given that I’ve already paid 3 times to test myself at 23andMe (V2, 3 and 4), I’m not keen on paying a 4th time for the V5 version.
  • 23andMe moved to the V5 Illumina GSA chip in August which is not compatible with any earlier chip versions.
  • Needless to say, the Illumina chip change has forced vendors away from focusing on new products in order to develop imputation code in order to remain backwards compatible with their own products from an earlier chip set.
  • GedMatch introduced their sandbox area, Genesis, where people can upload files that are not compatible with the traditional vendor files.  This includes the GSA chip results (23andMe V5,) exome tests and others.  The purpose of the sandbox is so that GedMatch can figure out how to work with these files that aren’t compatible with the typical autosomal test files.  The process has been interesting and enlightening, but people either don’t understand or forget that it’s a sandbox, an experiment, for all involved – including GedMatch.  Welcome to living on the genetic frontier!

  • I assembled a chart of who loves who – meaning which vendors accept transfers from which other vendors.

  • I suspect but don’t know that Ancestry is doing some form of imputation between their V1 and V2 chips. About a month before their new chip implementation in May of 2016, Ancestry made a change in their matching routine that resulting in a significant shift in people’s matches.

Because of Ancestry’s use of the Timber algorithm to downweight some segments and strip out others altogether, it’s difficult to understand where matching issues may arise.  Furthermore, there is no way to know that there are matching issues unless you and another individual have transferred results to either Family Tree DNA or GedMatch, neither of which remove any matching segments.

  • Other developments of note include the fact that Family Tree DNA moved to mitochondrial DNA build V17 and updated their Y DNA to hg38 of the human reference genome – both huge undertakings requiring the reprocessing of customer data. Think of both of those updates as housekeeping. No one wants to do it, but it’s necessary.
  • 23andMe FINALLY finished transferring their customer base to the “New Experience,” but many of the older features we liked are now gone. However, customers can now opt in to open matching, which is a definite improvement. 23andMe, having been the first company to enter the genetic genealogy autosomal matching marketspace has really become lackluster.  They could have owned this space but chose not to focus on genealogy tools.  In my opinion, they are now relegated to fourth place out of a field of 4.
  • Ancestry has updated their Genetic Communities feature a couple of times this year. Genetic Communities is interesting and more helpful than ethnicity estimates, but neither are nearly as helpful as a chromosome browser would be.

  • I’m sure that the repeated requests, begging and community level tantrum throwing in an attempt to convince Ancestry to produce a chromosome browser is beyond beating a dead horse now. That dead horse is now skeletal, and no sign of a chromosome browser. Sigh:(
  • The good news is that anyone who wants a chromosome browser can transfer their results to Family Tree DNA or GedMatch (both for free) and utilize a chromosome browser and other tools at either or both of those locations. Family Tree DNA charges a one time $19 fee to access their advanced tools and GedMatch offers a monthly $10 subscription. Both are absolutely worth every dime. The bad news is, of course, that you have to convince your match or matches to transfer as well.
  • If you can convince your matches to transfer to (or test at) Family Tree DNA, their tools include phased Family Matching which utilizes a combination of user trees, the DNA of the tester combined with the DNA of family matches to indicate to the user which side, maternal or paternal (or both), a particular match stems from.

  • Sites to keep your eye on include Jonny Perl’s tools which include DNAPainter, as well as Goran Rundfeldt’s DNA Genealogy Experiment.  You may recall that in October Goran brought us the fantastic Triangulator tool to use with Family Tree DNA results.  A few community members expressed concern about triangulation relative to privacy, so the tool has been (I hope only temporarily) disabled as the involved parties work through the details. We need Goran’s triangulation tool! Goran has developed other world class tools as well, as you can see from his website, and I hope we see more of both Goran and Jonny in 2018.
  • In 2017, a number of new “free” sites that encourage you to upload your DNA have sprung up. My advice – remember, there really is no such thing as a free lunch.  Ask yourself why, what’s in it for them.  Review ALL OF THE documents and fine print relative to safety, privacy and what is going to be done with your DNA.  Think about what recourse you might or might not have. Why would you trust them?

My rule of thumb, if the company is outside of the US, I’m immediately slightly hesitant because they don’t fall under US laws. If they are outside of Europe or Canada, I’m even more hesitant.  If the company is associated with a country that is unfriendly to the US, I unequivocally refuse.  For example, riddle me this – what happens if a Chinese (or fill-in-the-blank country) company violates an agreement regarding your DNA and privacy?  What, exactly, are you going to do about it from wherever you live?

2017 – The Year of Marketplace Apps

Third party genetics apps are emerging and are beginning to make an impact.

GedMatch, as always, has continued to quietly add to their offerings for genetic genealogists, as had DNAGedcom.com. While these two aren’t exactly an “app”, per se, they are certainly primary players in the third party space. I use both and will be publishing an article early in 2018 about a very useful tool at DNAGedcom.

Another application that I don’t use due to the complex setup (which I’ve now tried twice and abandoned) is Genome Mate Pro which coordinates your autosomal results from multiple vendors.  Some people love this program.  I’ll try, again, in 2018 and see if I can make it all the way through the setup process.

The real news here are the new marketplace apps based on Exome testing.

Helix and their partners offer a number of apps that may be of interest for consumers.  Helix began offering a “test once, buy often” marketplace model where the consumer pays a nominal price for exome sequencing ($80), significantly under market pricing ($500), but then the consumer purchases DNA apps through the Helix store. The apps access the original DNA test to produce results. The consumer does NOT receive their downloadable raw data, only data through the apps, which is a departure from the expected norm. Then again, the consumer pays a drastically reduced price and downloadable exome results are available elsewhere for full price.

The Helix concept is that lots of apps will be developed, meaning that you, the consumer, will be interested and purchase often – allowing Helix to recoup their sequencing investment over time.

Looking at the Helix apps that are currently available, I’ve purchased all of the Insitome products released to date (Neanderthal, Regional Ancestry and Metabolism), because I have faith in Spencer Wells and truthfully, I was curious and they are reasonably priced.

Aside from the Insitome apps, I think that the personalized clothes are cute, if extremely overpriced. But what the heck, they’re fun and raise awareness of DNA testing – a good thing! After all, who am I to talk, I’ve made DNA quilts and have DNA clothing too.

Having said that, I’m extremely skeptical about some of the other apps, like “Wine Explorer.”  Seriously???

But then again, if you named an app “I Have More Money Than Brains,” it probably wouldn’t sell well.

Other apps, like Ancestry’s WeRelate (available for smartphones) is entertaining, but is also unfortunately EXTREMELY misleading.  WeRelate conflates multiple trees, generally incorrectly, to suggest to you and another person on your Facebook friends list are related, or that you are related to famous people.  Judy Russell reviews that app here in the article, “No, actually, we’re not related.” No.  Just no!

I feel strongly that companies that utilize our genetic data for anything have a moral responsibility for accuracy, and the WeRelate app clearly does NOT make the grade, and Ancestry knows that.  I really don’t believe that entertaining customers with half-truths (or less) is more important than accuracy – but then again, here I go just being an old-fashioned fuddy dud expecting ethics.

And then, there’s the snake oil.  You knew it was going to happen because there is always someone who can be convinced to purchase just about anything. Think midnight infomercials. The problem is that many consumers really don’t know how to tell snake oil from the rest in the emerging DNA field.

You can now purchase DNA testing for almost anything.  Dating, diet, exercise, your taste in wine and of course, vitamins and supplements. If you can think of an opportunity, someone will dream up a test.

How many of these are legitimate or valid?  Your guess is as good as mine, but I’m exceedingly suspicious of a great many, especially those where I can find no legitimate scientific studies to back what appear to be rather outrageous claims.

My main concern is that the entire DTC testing industry will be tarred by the brush of a few unethical opportunists.

2017 – The Year of Focus on Privacy and Security

With increased consumer exposure comes increased notoriety. People are taking notice of DNA testing and it seems that everyone has an opinion, informed or not.  There’s an old saying in marketing; “Talk about me good, talk about me bad, just talk about me.”

With all of the ads have come a commensurate amount of teeth gnashing and “the-sky-is-falling” type reporting.  Unfortunately, many politicians don’t understand this industry and open mouth only to insert foot – except that most people don’t realize what they’ve done.  I doubt that the politicians even understand that they are tasting toe-jam, because they haven’t taken the time to research and understand the industry. Sound bites and science don’t mix well.

The bad news is that next, the click-bait-focused press picks up on the stories and the next time you see anyone at lunch, they’re asking you if what they heard is true.  Or, let’s hope that they ask you instead of just accepting what they heard as gospel. Hopefully if we’ve learned anything in this past year, it’s to verify, verify, verify.

I’ve been an advocate for a very long time of increased transparency from the testing companies as to what is actually done with our DNA, and under what circumstances.  In other words, I want to know where my DNA is and what it’s being used for.  Period.

Family Tree DNA answered that question succinctly and unquestionably in December.

Bennett Greenspan: “We could probably make a lot of money by selling the DNA data that we’ve been collecting over the years, but we feel that the only person that should have your DNA information is you.  We don’t believe that it should be sold, traded or bartered.”

You can’t get more definitive than that.

DTC testing for genetic genealogy must be a self-regulating field, because the last thing we need is for the government to get involved, attempting to regulate something they don’t understand.  I truly believe government interference by the name of regulation would spell the end of genetic genealogy as we know it today.  DNA testing for genetic genealogy without sharing results is entirely pointless.

I’ve written about this topic in the past, but an update is warranted and I’ll be doing that sometime after the first of the year.  Mostly, I just need to be able to stay awake while slogging through the required reading (at some vendor sites) of page after page AFTER PAGE of legalese😊

Consumers really shouldn’t have to do that, and if they do, a short, concise summary should be presented to them BEFORE they purchase so that they can make a truly informed decision.

Stay tuned on this one.

2017 – The Year of Education

The fantastic news is that with all of the new people testing, a huge, HUGE need for education exists.  Even if 75% of the people who test don’t do anything with their results after that first peek, that still leaves a few million who are new to this field, want to engage and need some level of education.

In that vein, seminars are available through several groups and institutes, in person and online.  Almost all of the leadership in this industry is involved in some educational capacity.

In addition to agendas focused on genetic genealogy and utilizing DNA personally, almost every genealogy conference now includes a significant number of sessions on DNA methods and tools. I remember the days when we were lucky to be allowed one session on the agenda, and then generally not without begging!

When considering both DNA testing and education, one needs to think about the goal.  All customer goals are not the same, and neither are the approaches necessary to answer their questions in a relevant way.

New testers to the field fall into three primary groups today, and their educational needs are really quite different, because their goals, tools and approaches needed to reach those goals are different too.

Adoptees and genealogists employ two vastly different approaches utilizing a common tool, DNA, but for almost opposite purposes.  Adoptees wish to utilize tests and trees to come forward in time to identify either currently living or recently living people while genealogists are interested in reaching backward in time to confirm or identify long dead ancestors. Those are really very different goals.

I’ve illustrated this in the graphic above.  The tester in question uses their blue first cousin match to identify their unknown parent through the blue match’s known lineage, moving forward in time to identify the tester’s parent.  In this case, the grandparent is known to the blue match, but not to the yellow tester. Identifying the grandparent through the blue match is the needed lynchpin clue to identify the unknown parent.

The yellow tester who already knows their maternal parent utilizes their peach second cousin match to verify or maybe identify their maternal great-grandmother who is already known to the peach match, moving backwards in time. Two different goals, same DNA test.

The three types of testers are:

  • Curious ethnicity testers who may not even realize that at least some of the vendors offer matching and other tools and services.
  • Genealogists who use close relatives to prove which sides of trees matches come from, and to triangulate matching segments to specific ancestors. In other words, working from the present back in time. The peach match and line above.
  • Adoptees and parent searches where testers hope to find a parent or siblings, but failing that, close relatives whose trees overlap with each other – pointing to a descendant as a candidate for a parent. These people work forward in time and aren’t interested in triangulation or proving ancestors and really don’t care about any of those types of tools, at least not until they identify their parent.  This is the blue match above.

What these various groups of testers want and need, and therefore their priorities are different in terms of their recommendations and comments in online forums and their input to vendors. Therefore, you find Facebook groups dedicated to Adoptees, for example, but you also find adoptees in more general genetic genealogy groups where genealogists are sometimes surprised when people focused on parent searches downplay or dismiss tools such as Y DNA, mitochondrial DNA and chromosome browsers that form the bedrock foundation of what genealogists need and require.

Fortunately, there’s room for everyone in this emerging field.

The great news is that educational opportunities are abundant now. I’m listing a few of the educational opportunities for all three groups of testers, in addition to my blog of course.😊

Remember that this blog is fully searchable by keyword or phrase in the little search box in the upper right hand corner.  I see so many questions online that I’ve already answered!

Please feel free to share links of my blog postings with anyone who might benefit!

Note that these recommendations below overlap and people may well be interested in opportunities from each group – or all!!

2018 – What’s Ahead? 

About midyear 2018, this blog will reach 1000 published articles. This is article number 939.  That’s amazing even to me!  When I created this blog in July of 2012, I wasn’t sure I’d have enough to write about.  That certainly has changed.

Beginning shortly, the tsunami of kits that were purchased during the holidays will begin producing matches, be it through DNA upgrades at Family Tree DNA, Big Y tests which were hot at year end, or new purchases through any of the vendors.  I can hardly wait, and I have my list of brick walls that need to fall.

Family Tree DNA will be providing additional STR markers extracted from the Big Y test. These won’t replace any of the 111 markers offered separately today, because the extraction through NGS testing is not as reliable as direct STR testing for those markers, but the Big Y will offer genealogists a few hundred more STRs to utilize. Yes, I said a few hundred. The exact number has not yet been finalized.

Family Tree DNA says they will also be introducing new “qualify of life improvements” along with new privacy and consent settings.  Let’s hope this means new features and tools will be released too.

MyHeritage says that they are introducing new “Discoveries” pages and a chromosome browser in January.  They have also indicated that they are working on their matching issues.  The chromosome browser is particularly good news, but matching must work accurately or the chromosome browser will show erroneous information.  Let’s hope January brings all three features.

LivingDNA indicates that they will be introducing matching in 2018.

2018 – What Can You Do?

What can you do in 2018 to improve your odds of solving genealogy questions?

  • Test relatives
  • Transfer your results to as many data bases as possible (among the ones discussed above, after reading the terms and conditions, of course)
  • If you have transferred a version of your DNA that does not produce full results, such as the Ancestry V2 or 23andMe V4 test to Family Tree DNA, consider testing on the vendor’s own chip in order to obtain all matches, not just the closest matches available from an incompatible test transfer.
  • Test Y and mitochondrial DNA at Family Tree DNA.
  • Find ways to share the stories of your ancestors.  Stories are cousin bait.  My 52 Ancestors series is living proof.  People find the stories and often have additional facts, information or even photos. Some contacts qualify for DNA testing for Y or mtDNA lines. The GREAT NEWS is that Amy Johnson Crow is resuming the #52Ancestors project for 2018, providing hints and tips each week! Who knows what you might discover by sharing?! Here’s how to start a blog if you need some assistance.  It’s easy – really!
  • Focus on the brick walls that you want to crumble and then put together both a test and analysis plan. That plan could include such things as:

o   Find out if a male representing a Y line in your tree has tested, and if not, search through autosomal results to see if a male from that paternal surname line has tested and would be amenable to an upgrade.

o   Mitochondrial DNA test people who descend through all females from various female ancestors in order to determine their origins. Y and mtDNA tests are an important part of a complete genealogy story – meaning the reasonably exhaustive search!

o   Autosomal DNA test family members from various lines with the hope that matches will match you and them both.

o   Test family members in order to confirm a particular ancestor – preferably people who descend from another child of that ancestor.

o   Making sure your own DNA is in all 4 of the major vendors’ data bases, plus GedMatch. Look at it this way, everyone who is at GedMatch or at a third party (non-testing) site had to have tested at one of the major 4 vendors – so if you are in all of the vendor’s data bases, plus GedMatch, you’re covered.

Have a wonderful New Year and let’s make 2018 the year of newly discovered ancestors and solved mysteries!

Using Spousal Surnames and DNA to Unravel Male Lines

When Y DNA matching at Family Tree DNA, it’s not uncommon for men to match other males of the same surname who share the same ancestor. In fact, that’s what we hope for, fervently!

However, if you’re stuck downstream, you may need to figure out which of several male children you descend from.

If you’re staring at a brick wall working yourselves back in time, you may need to try working forward, utilizing various types of information, including wives’ surnames.

For all intents and purposes, this is my Vannoy line, in Wilkes County, NC, so let’s use it as an example, because it embodies both the promise and the peril of this approach.

So, there you sit, disconnected from the Vannoy line. That little yellow box is just so depressing. So close, but yet so far. And yes, we’ve already exhausted the available paper trail records, years ago.

We know the lineage back through Elijah Vannoy, who was born between 1784-1786 in Wilkes County, or vicinity. We know my Vannoy cousin Y DNA matches with other men from the Vannoy line upstream of John Francis Vannoy, the known father of four sons in Wilkes County, NC and the first (and only) Vannoy to move from New Jersey to that part of North Carolina.

Therefore, we know who the candidates are to be Elijah’s father, but the connection in the yellow box is missing. Many Wilkes County records have gone missing over the years and births were not recorded in that timeframe.  The records from neighboring Ashe County where Daniel Vannoy lived burned during the Civil War, although some records did survive. In other words, the records are rather like Swiss cheese. Welcome to genealogy in the south.

Which of John Francis Vannoy’s four sons does Elijah descend from?

Let’s see what we can discover.

Contact Matches and Ask for Help

The first thing I would do is to ask for assistance from your surname matches.

Let’s say that you match a known descendant of each of these four men, meaning each of John Francis Vannoy’s sons. Ask each person if they know where the male Vannoy descendants of each son went along with any documentation they might have. If your ancestor, Elijah in this case, is not found in the same location as the sons, geography may be your friend.

In our case, we know that Francis Vannoy migrated to Knox County, Kentucky, but that was after he signed for his daughter’s marriage in Wilkes Co., NC in 1812. It was also about this time that Elijah Vannoy migrated to Claiborne County, TN, in the same direction, but not the same location. The two locations are an hour away by car today, separated by mountains and the Cumberland Gap, a nontrivial barrier.

We also know that Nathaniel Vannoy left a Bible that did not list Elijah as one of his children, but with a gap large enough to possibly encompass another child.  If you’re thinking to yourself, “Who would leave a child’s birth out of the Bible?,” I though the same thing until I encountered it myself personally in another line.  However, the Bible record does make Nathaniel a less likely father candidate, despite a persistent rumor that Nathaniel was Elijah’s father.

Our only other clues are some tax records recording the number of children in the household of various ages, but none are conclusive. None of these men had wills.

Y DNA Genetic Distance

Your Y DNA matches will show how many mutations you are from them at a particular marker level.

Please note that you can click to enlarge any graphic.

The number of mutations between two men is called the genetic distance.

The rule of thumb is that the more mutations, the further back in time the common ancestor. The problem is, the rule of thumb doesn’t always work. DNA mutates when it darned well pleases, not on any clock that we can measure with that degree of accuracy – at least not accurately enough to tell which of 4 sons a man descends from – unless that line has incurred a defining mutation between the ancestor and the current generation. We call those line marker mutations. To determine the mutation history, you need multiple men from each line to have tested.

You can read more about Y DNA matching in the article, Concepts – Y DNA Matching and Connecting with your Paternal Ancestor.

Check Autosomal DNA Tests

Next, check to see if your Y DNA matches from all Vannoy lines have also taken the autosomal Family Finder test, noted as FF, which shows matches from all ancestral lines, not just the paternal line.

You can see in the match list above that not many have taken the Family Finder test. Ask if they would be willing to upgrade. Be prepared to pay if need be – because you are, after all, the one with the “problem” to solve.

Generally, I simply offer to pay. It’s well worth it to me, and given that paper records don’t exist to answer the question – a DNA test under $100 is cheap. Right now, Family Finder tests are on sale for $69 until the end of the month.

Check for Intermarriage

While you’re waiting for autosomal DNA results, check the pedigrees for all for lines involved to see if you are otherwise related to these men or their wives.

For example, in Andrew Vannoy’s wife’s line and Elijah Vannoy’s wife’s line, we have a common ancestor. George Shepherd and Elizabeth Mary Angelique Daye are common to both lines, and John Shepherd’s wife is unknown, so we have one known problem and one unknown surname.

You can tell already that this could be messy, because we can’t really use Andrew Vannoy’s wife’s line to search for matches because Elijah’s line is likely to match through Andrew’s wife since Susannah Shepherd and Lois McNiel share a common lineage. Rats!

We’ll mark these in red to remind ourselves.

Check Advanced Matching

Family Tree DNA provides a wonderful tool that allows you to compare matches of different kinds of DNA. The Advanced Matching tab is found under “Tools and Apps” under the myFTDNA tab at the upper left.

In this case, I’m going to use the Advanced Match feature to see which of my Vannoy cousin’s Y matches at 37 markers, within the Vannoy DNA project, also match him autosomally.

This report is particularly nice, because it shows number of Y mutations, often indicating distance to a common ancestor, as well as the estimated autosomal relationship range.

You can see in this case that the first Vannoy male, “A,” is a close match both on Y DNA and autosomally, with 1 mutation difference and falling in the 2nd to 4th cousin range, as compared to the second Vannoy male, “D,” who is 3 mutations different and falls into the 4th to remote cousin range.

Not every Vannoy male may have joined the Vannoy project, so you’ll want to run this report a second time, replacing the Vannoy project search criteria with “The Entire Database.”

Unfortunately, not everyone that I need has taken the Family Finder test, so I’ll be contacting a few men, asking if I can sponsor their upgrades.

Let’s move on to our next tactic, using the wives’ surnames.

Search Utilizing the Wife’s Surname

We already know that we can’t rely on the Shepherd surname, so we’ll have to utilize the surnames of the other three wives:

  • Millicent Henderson – parents Thomas Henderson born circa 1730 Virginia, died 1806 Laurens, SC, wife Frances, surname unknown
  • Elizabeth Ray (Raye) – parents William Ray born circa 1725/1730 Herdford, England, died 1783 Wilkes Co., NC (the portion now Ashe Co.,) wife Elizabeth Gordon born circa 1783 Amherst Co., VA and died 1804 Surry Co., NC
  • Sarah Hickerson – parents Charles Hickerson born circa 1725 Stafford Co., VA, died before 1793 Wilkes Co., NC, wife Mary Lytle

Utilizing the Family Finder match search function, I’m going to search for matches that include the wives surnames, but are NOT descended from the Vannoy line.

Hickerson produced no non-Vannoy matches utilizing the matches of my first Vannoy cousin, but Henderson is another matter entirely.

Since the Henderson line would be on my cousin’s father’s side, the matches that are most relevant are the ones phased to his paternal line, those showing the blue person icon.

The surname that you have entered as the search criteria will show as blue in the Ancestral Surname list, at far right, and other matching surnames will show as black. Please note that this includes surnames from ANY person in the match’s tree if they have uploaded a Gedcom file, not just surnames of direct ancestral lines. Therefore, if the match has a tree, it’s important to click on the pedigree icon and search for the surname in question. Don’t assume.

Altogether, there are 76 Henderson matches, of which 17 are phased to his paternal line. You’ll need to review each one of at least the 17. Personally, I would painstakingly review each one of the 76. You never know where a shred of information will be found.

Please note, finding a match with a common surname DOES NOT MEAN THAT YOU MATCH THIS PERSON THROUGH THAT SURNAME. Even finding a person with a common ancestor doesn’t mean that you both descend from that ancestor. You may have a second common ancestor. It means that you have more work to do, as proof, but it’s the beginning you need.

Of course, the first thing we need to do is eliminate any matches who also descend from a Vannoy, because there is no way to know if the matching DNA is through the Vannoy or Henderson lines. However, first, take note of how that person descends from the Vannoy line.

You can see your matches entire surname list by clicking on their profile picture.

The surname, Ray, is more difficult, because the search for Ray also returns names like Bray and Wray, as well as Ray.

But Wait – There’s a Happy Ending!

If you’re thinking, “this is a lot of work,” yes, it is.

Yes, you are absolutely going to do the genealogy of the wives’ lines so you can recognize if and how your matches might connect.

I enter the wives’ lines into my genealogy software and then I search for the ancestors found in my matches trees to see if they descend from that line.

One tip to make this easier is to test multiple people in the same line – regardless of whether they are males or carry the desired surname. They simply need to be descendants – that’s the beauty of autosomal DNA and why I carry kits with me wherever I go.  And yes, I’m really serious about that!

When you have multiple testers from the same line, you can utilize each test independently, searching for each surname in the Family Finder results.  Then, from the surname match list, select a sibling or other close relative with that same surname in their list, then choose the ICW feature. This allows you to see who both of those people match who also carries the Henderson surname in their surname list.

Not successful with that initial cousin’s match results – like I wasn’t with Hickerson?

Rinse and repeat, with every single person who you can find who has descended from the line in question. I started the process over again with a second cousin and a Hickerson search.

About the time you’re getting really, really tired of looking at all of those trees, extending the branches of other people’s lines, and are about to give up and go to bed because it’s 3 AM and you’re discouraged, you see something like this:

Yep, it’s good old Charles Hickerson and Mary Lytle.  I could hardly believe my eyes!!! This Hickerson match to a cousin in my Vannoy line descends from Charles Hickerson’s son, Joshua.

All of a sudden…it’s all worthwhile! Your fatigue is gone, replaced by adrenalin and you couldn’t sleep now if your life depended on it!

Using the ICW (in common with feature) to find additional known cousins who match the person with Charles Hickerson and Mary Lytle in their tree, I found a total of three Vannoy cousins with significant matches.

Using the chromosome browser to compare, I’ve confirmed that one segment is a triangulated match of 12.69 cM (blue) on chromosome 2.

You can read more about triangulation in the article, Concepts – Why Genetic Genealogy and Triangulation? as well as the article, Concepts – Match Groups and Triangulation.

Do I wish I had more than three people in my triangulation group? Yes, of course, but with a match of this size triangulated between cousins and a Hickerson descendant who is a 30 year genealogist, sporting a relatively complete tree and no other common lines, it’s a great place to begin digging deeper! This isn’t the end, but a new beginning!

After obsessively digging through the matches of every Elijah Vannoy descended cousin I can find (sleep is overrated anyway) and whose account I have access to, I have now discovered matches with four additional people who have no other common lines with the Vannoy cousins and who descend from Charles Hickerson and Mary Lytle through sons David and Joseph Hickerson. I can’t tell if they triangulate without access to accounts that I don’t have access to, so I’ve sent e-mails requesting additional information.

WooHoo Happy Day!!! There’s a really big crack in the brick wall and I’ve just witnessed the sunrise of a beautiful, amazing day.

I think Elijah’s parents are…drum roll…Daniel Vannoy and Sarah Hickerson!

Which walls do you need to fall and how can you use this technique?

Concepts – Why Genetic Genealogy and Triangulation?

One of the questions often asked is why triangulation in genetic genealogy is so important.

Before I answer that, let’s take a look at why genealogists use autosomal DNA for genetic genealogy in the first place.

Why Genetic Genealogy?

Aside from ethnicity testing, genetic genealogists utilize autosomal DNA testing to further their genealogical research or confirm the research they have already performed. Genetic genealogy cannot stand alone on DNA evidence, but must include traditional genealogical research. DNA is simply another tool in the genealogist’s tool box – albeit a critical one.

There are three established primary vendors in this field, Family Tree DNA, Ancestry and 23andMe, plus a few newcomers. All three vendors offer autosomal DNA tests utilized by genetic genealogists in various ways. If you want to learn more about the differences between these vendors’ offerings, please read the article, “Which DNA Test is Best?”

In order to achieve genealogical goals, there are four criteria that need to be met. All are required to achieve triangulation which is the only way to confirm a genealogical ancestral match to a specific ancestor.

  • DNA Matching – The tester’s DNA matches that of other testers at the company where they tested, or at GedMatch. All three vendors provide matching information, along with GedMatch, a third-party tool utilized by genetic genealogists.

Family Tree DNA assigns matches to either maternal, paternal or both sides of the tester’s tree based on connecting the DNA of relatives, up through third cousins, who have tested to their appropriate location in the tester’s tree.

In the example above, you can see the individuals linked to my tree include my mother with her Family Finder test, plus her two first cousins, Donald and Cheryl Ferverda who have also tested.

  • Ancestor Matching – The testers identify a common ancestor or ancestral line based on their previous work, aka, genealogy and family trees.  In the example above, the common ancestors are the parents of the brothers, John and Roscoe Ferverda.  Identifying a common ancestor is an easy task with known close relatives, but becomes more challenging the more distant the common ancestor.

Of the vendors, 23andMe does not have a Gedcom upload or ability for testers to display trees and for the vendor to utilize to match surnames, although they can link to external trees. Ancestry provides “tree matching,” shown above, and Ancestry and Family Tree DNA, shown below, both provide surname matching.

  • Segment Matching – Utilizing chromosome browsers or downloaded match lists including segment information to identify actual DNA segments that match other testers.

Family Tree DNA’s chromosome browser is shown above.

Each individual tester will have two groups of matches on the same segment, one group from their mother’s side of the tree and one from their father’s side of the tree. Each tester carries DNA inherited from both parents on two different “sides” of each chromosome. You can read more about that in the article, One Chromosome, Two Sides, No Zipper – ICW and the Matrix.

Of the three vendors, Ancestry does not provide segment matching, a chromosome browser, nor any segment information, so testers cannot perform this step at Ancestry.

23andMe does provide this information, but each tester must individually “opt in” to data sharing, and many do not. If testers do not globally “opt in” they must authorize sharing individually for every match, so testers will not be able to see the chromosome segment information for many 23andMe matches. In my case, only about 60% are sharing.

Family Tree DNA provides a chromosome browser, the file download capability with segment information, and everyone authorizes sharing of information when they initially test – so there is no opt-in confusion.

Ancestry and 23andMe raw DNA data files can be transferred to both Family Tree DNA and GedMatch where chromosome browsers and other tools are available. For more information about transferring files, please read Autosomal DNA Transfers – Which Companies Accept Which Tests?

Triangulation – The process used to combine all three of the above steps in order to assign specific segments of the tester’s DNA to specific ancestors, by virtue of:

  • The tester’s DNA matching the DNA of other testers on a specific segment.
  • Identifying that the individuals who match the tester on that segment also match each other. This is part of the methodology employed to group the testers matches into two groups, the maternal and paternal groupings.
  • Identifying which ancestor contributed that segment to all of the people who match the tester and each other on that same segment.

In order for a group of matches to triangulate, they must match each other on the same segment of DNA and they must all share a common ancestor.

Triangulation is part DNA, meaning the inheritance, part technology, meaning the ability to show that all testers in a match group all match each other and on the same segment, and part genealogy, meaning the ability to identify the common ancestor of the group of individuals.

The following chart shows a portion of my match download file on chromosome 5 from Family Tree DNA.

As you can see, these matches all cover significant portions of the same segment on chromosome 5.

Without further investigation, we know that I match all of these people, but we don’t know what that information is telling us about my genealogy. We don’t know who matches each other, and we can’t tell which people are from my mother’s and father’s sides. We also don’t know who the common ancestor is or common ancestors are.

However, looking at the trees of the individuals involved, or contacting them for further information, and/or recognizing known cousins from a specific line all combine to contribute to the identification of our common ancestors.

Below is the same spreadsheet, now greatly enriched after my genealogy work is applied to the DNA matches in two additional columns.

I’ve colored my triangulated groups pink for my mother’s side and blue for my father’s side.

In this case, I also have access to my cousins’ DNA match results, so I can view their matches as well, looking for common matches on my match list.

One of the reasons genealogists always suggest testing older family members and as many cousins as possible is because triangulation becomes much easier with known cousins from particular lines to point the way to the common ancestor. In this case, one cousin, Joe, is from my mother’s side and one, Lou, is from my father’s side.

By looking at my matches’ genealogy, I’ve now been able to assign this particular segment on chromosome 5, on my mother’s side to ancestors Johann Michael Miller and his wife Susanna Berchtol. The same segment, on my father’s side is inherited from Charles Dodson and his wife, Ann, last name unknown.

In order to achieve triangulation, the common ancestor must be determined for the match group. Once triangulation is achieved, descent from the common ancestor is confirmed.

Unless you are dealing with very close known relatives, like the Ferverda first cousins, there is no other way to prove a genetic connection to a specific ancestor.

At Family Tree DNA, I can utilize the chromosome browser and the ICW and matrix tools to determine which of this group matches each other. At 23andMe, I can utilize their shared DNA matching tool. This information can then be recorded in my DNA spreadsheet, as illustrated above.

Triangulation cannot be achieved at Ancestry or utilizing their tools. Ancestry’s DNA Circles provide extended match groups, indicating who matches whom for a particular ancestor shown in a tester’s tree, but do not indicate that the matches are on the same segment. Circles do not guarantee that Circle members are matching on DNA from that ancestor, only that they do match and show a common ancestor in their tree.  The third triangulation step of segment matching is missing.  Ancestry does not provide segment information in any format, so Ancestry customers who want to triangulate can either retest elsewhere or download their data files to either Family Tree DNA or GedMatch for free.

Summary

Before the advent of genetic genealogy, genealogists had to take it on faith that the paper trail was accurate, and that there was no misattributed parentage – either through formal or informal adoption or hanky-panky.  That’s not the case anymore.

Today, DNA through triangulation can prove ancestry for groups of people to a common ancestor by identifying segments that have descended from that ancestor and are found in multiple descendants today.

Of course, the next step is to break down those remaining brick walls. For example, what is the birth name of Ann, wife of Charles Dodson, whose surname is unknown? Logically, the DNA descended from a couple, meaning Charles and Ann, contains DNA from both individuals. We don’t know if that segment on chromosome 5 is from Ann, Charles, or parts from both, BUT, if we begin to see a further breakdown to another, unknown family line among the Charles and Ann segments, that might be a clue.

One day, in the future, we’ll be able to identify our unknown family lines through DNA matches and other people’s triangulation. That indeed, is the Holy Grail.

If you think you might come up short, because you have only one known cousin who has tested, well, think again.

Here’s wishing you lots of triangulated matches!!!
