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.

The theory is displayed in summary format first.

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

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!

Testing Strategy – Should I Test at Ancestry and Transfer to Family Tree DNA?

As most people know by now, Ancestry doesn’t accept DNA file transfers from other vendors, so many people recommend testing first at Ancestry and then transferring to Family Tree DNA.

Actually, that’s not always the best choice.

  • There is nothing inherently WRONG with that strategy, but it may not be right for you either. Transferring to Family Tree DNA from Ancestry certainly won’t hurt anything, but a transfer will only provide 20-25% of your matches if you tested at Ancestry after May of 2016 because the DNA chips used for processing are different at the two vendors.
  • If you tested at Ancestry before May of 2016, the Ancestry kit and the Family Tree DNA kits are identical, so transferring will give you the same matches at Family Tree DNA as if you had tested there. You are on the Ancestry V1 kit, so just transfer.  There is no need for a V1 kit to retest at Family Tree DNA. The transfer itself is free, as are your matches, but to unlock all features and tools costs $19. A bargain.
  • If you tested at Ancestry after May of 2016, you tested on the V2 kit. Ancestry changed the markers tested and now the Ancestry kit is only partially compatible with Family Tree DNA. As an Ancestry V2 transfer kit, you will only receive about 20-25% of the matches you would receive if you tested at Family Tree DNA.  The matches you receive will be your closest matches, but is that enough?

For some people, especially adoptees, your closest matches may be all that you are interested in.  If so, you’re golden with any Ancestry transfer.

For genealogists, you’re missing 75-80% of your matches, and your brick-wall breaker may well be in that group. Not good at all!

Let’s look at my kits for example.  I have tested directly at Family Tree DNA, and I have also transferred an Ancestry V2 kit to Family Tree DNA.

As you can see, my Family Finder kit received 3115 matches.  My Ancestry V2 transfer kit only received 26.65% of those matches.

Plus, if you attach the DNA of known family members to your tree, Family Tree DNA provides phased matching, which tells you which side of your tree a match connects to.  In the example above, that means that I know immediately which side 1236 of my matches connect to.  That’s a whopping 40% and that’s before I even look at their trees or common surnames! This is an incredible tool.

People who recommend that you test at Ancestry, today, and transfer to Family Tree DNA may not understand the unintended consequences, or they may be people who work primarily with adoptees. They may also not understand the value of phased matches for genealogists.

For people who tested at Ancestry after May of 2016, my recommendation is to take the Family Finder test directly at Family Tree DNA as well as test at Ancestry separately.

If you tested at MyHeritage, that test is fully compatible at Family Tree DNA as well, so do transfer, no retest needed!

To Order or Transfer

To transfer to Family Tree DNA for free from any company, click here and then in the upper left hand corner of the screen, click Autosomal Transfer, last option under the dropdown under the blue DNA Tests to get started.

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?

Which DNA Test is Best?

If you’re reading this article, congratulations. You’re a savvy shopper and you’re doing some research before purchasing a DNA test. You’ve come to the right place.

The most common question I receive is asking which test is best to purchase. There is no one single best answer for everyone – it depends on your testing goals and your pocketbook.

Testing Goals

People who want to have their DNA tested have a goal in mind and seek results to utilize for their particular purpose. Today, in the Direct to Consumer (DTC) DNA market space, people have varied interests that fall into the general categories of genealogy and medical/health.

I’ve approached the question of “which test is best” by providing information grouped into testing goal categories.  I’ve compared the different vendors and tests from the perspective of someone who is looking to test for those purposes – and I’ve created separate sections of this article for each interest..

We will be discussing testing for:

  • Ethnicity – Who Am I? – Breakdown by Various World Regions
  • Adoption – Finding Missing Parents or Close Family
  • Genealogy – Cousin Matching and Ancestor Search/Verification
  • Medical/Health

We will be reviewing the following test types:

  • Autosomal
  • Y DNA (males only)
  • Mitochondrial DNA

I have included summary charts for each section, plus an additional chart for:

  • Additional Vendor Considerations

If you are looking to select one test, or have limited funds, or are looking to prioritize certain types of tests, you’ll want to read about each vendor, each type of test, and each testing goal category.

Each category reports information about the vendors and their products from a different perspective – and only you can decide which of these perspectives and features are most important to you.

You might want to read this short article for a quick overview of the 4 kinds of DNA used for genetic genealogy and DTC testing and how they differ.

The Big 3

Today, there are three major players in the DNA testing market, not in any particular order:

Each of these companies offers autosomal tests, but each vendor offers features that are unique. Family Tree DNA and 23andMe offer additional tests as well.

In addition to the Big 3, there are a couple of new kids on the block that I will mention where appropriate. There are also niche players for the more advanced genetic genealogist or serious researcher, and this article does not address advanced research.

In a nutshell, if you are serious genealogist, you will want to take all of the following tests to maximize your tools for solving genealogical puzzles. There is no one single test that does everything.

  • Full mitochondrial sequence that informs you about your matrilineal line (only) at Family Tree DNA. This test currently costs $199.
  • Y DNA test (for males only) that informs you about your direct paternal (surname) line (only) at Family Tree DNA. This test begins at $169 for 37 markers.
  • Family Finder, an autosomal test that provides ethnicity estimates and cousin matching at Family Tree DNA. This test currently costs $89.
  • AncestryDNA, an autosomal test at Ancestry.com that provides ethnicity estimates and cousin matching. (Do not confuse this test with Ancestry by DNA, which is not the same test and does not provide the same features.) This test currently costs $99, plus the additional cost of a subscription for full feature access. You can test without a subscription, but nonsubscribers can’t access all of the test result features provided to Ancestry subscribers.
  • 23andMe Ancestry Service test, an autosomal test that provides ethnicity estimates and cousin matching. The genealogy version of this test costs $99, the medical+genealogy version costs $199.

A Word About Third Party Tools

A number of third party tools exist, such as GedMatch and DNAGedcom.com, and while these tools are quite useful after testing, these vendors don’t provide tests. In order to use these sites, you must first take an autosomal DNA test from a testing vendor. This article focuses on selecting your DNA testing vendor based on your testing goals.

Let’s get started!

Ethnicity

Many people are drawn to DNA testing through commercials that promise to ‘tell you who you are.” While the allure is exciting, the reality is somewhat different.

Each of the major three vendors provide an ethnicity estimate based on your autosomal DNA test, and each of the three vendors will provide you with a different result.

Yep, same person, different ethnicity breakdowns.

Hopefully, the outcomes will be very similar, but that’s certainly not always the case. However, many people take one test and believe those results wholeheartedly. Please don’t. You may want to read Concepts – Calculating Ethnicity Percentages to see how varied my own ethnicity reports are at various vendors as compared to my known genealogy.

The technology for understanding “ethnicity” from a genetic perspective is still very new. Your ethnicity estimate is based on reference populations from around the world – today. People and populations move, and have moved, for hundreds, thousands and tens of thousands of years. Written history only reaches back a fraction of that time, so the estimates provided to people today are not exact.

That isn’t to criticize any individual vendor. View each vendor’s results not as gospel, but as their opinion based on their reference populations and their internal proprietary algorithm of utilizing those reference populations to produce your ethnicity results.

To read more about how ethnicity testing works, and why your results may vary between vendors or not be what you expected, click here.

I don’t want to discourage anyone from testing, only to be sure consumers understand the context of what they will be receiving. Generally speaking, these results are accurate at the continental level, and less accurate within continents, such as European regional breakdowns.

All three testing companies provide additional features or tools, in addition to your ethnicity estimates, that are relevant to ethnicity or population groups.

Let’s look at each company separately.

Ethnicity – Family Tree DNA

Family Tree DNA’s ethnicity tool is called myOrigins and provides three features or tools in addition to the actual ethnicity estimate and associated ethnicity map.

Please note that throughout this article you can click on any image to enlarge.

On the myOrigins ethnicity map page, above, your ethnicity percentages and map are shown, along with two additional features.

The Shared Origins box to the left shows the matching ethnic components of people on your DNA match list. This is particularly useful if you are trying to discover, for example, where a particular minority admixture comes from in your lineage. You can select different match types, for example, immediate relatives or X chromosome matches, which have special inheritance qualities.

Clicking on the apricot (mitochondrial DNA) and green (Y DNA) pins in the lower right corner drops the pins in the locations on your map of the most distant ancestral Y and mitochondrial DNA locations of the individuals in the group you have selected in the Shared Origins match box. You may or may not match these individuals on the Y or mtDNA lines, but families tend to migrate in groups, so match hints of any kind are important.

A third unique feature provided by Family Tree DNA is Ancient Origins, a tool released with little fanfare in November 2016.

Ancient Origins shows the ancient source of your European DNA, based on genome sequencing of ancient DNA from the locations shown on the map.

Additionally, Family Tree DNA hosts an Ancient DNA project where they have facilitated the upload of the ancient genomes so that customers today can determine if they match these ancient individuals.

Kits included in the Ancient DNA project are shown in the chart below, along with their age and burial location. Some have matches today, and some of these samples are included on the Ancient Origins map.

Individual Approx. Age Burial Location Matches Ancient Origins Map
Clovis Anzick 12,500 Montana (US) Yes No
Linearbandkeramik 7,500 Stuttgart, Germany Yes Yes
Loschbour 8,000 Luxembourg Yes Yes
Palaeo-Eskimo 4,000 Greenland No No
Altai Neanderthal 50,000 Altai No No
Denisova 30,000 Siberia No No
Hinxton-4 2,000 Cambridgeshire, UK No No
BR2 3,200 Hungary Yes Yes
Ust’-Ishim 45,000 Siberia Yes No
NE1 7,500 Hungary Yes Yes

Ethnicity – Ancestry

In addition to your ethnicity estimate, Ancestry also provides a feature called Genetic Communities.

Your ethnicity estimate provides percentages of DNA found in regions shown on the map by fully colored shapes – green in Europe in the example above. Genetic Communities show how your DNA clusters with other people in specific regions of the world – shown with dotted clusters in the US in this example.

In my case, my ethnicity at Ancestry shows my European roots, illustrated by the green highlighted areas, and my two Genetic Communities are shown by yellow and red dotted regions in the United States.

My assigned Genetic Communities indicate that my DNA clusters with other people whose ancestors lived in two regions; The Lower Midwest and Virginia as well as the Alleghenies and Northeast Indiana.

Testers can then view their DNA matches within that community, as well as a group of surnames common within that community.

The Genetic Communities provided for me are accurate, but don’t expect all of your genealogical regions to be represented in Genetic Communities. For example, my DNA is 25% German, and I don’t have any German communities today, although ancestry will be adding new Genetic Communities as new clusters are formed.

You can read more about Genetic Communities here and here.

Ethnicity – 23andMe

In addition to ethnicity percentage estimates, called Ancestry Composition, 23andMe offers the ability to compare your Ancestry Composition against that of your parent to see which portions of your ethnicity you inherited from each parent, although there are problems with this tool incorrectly assigning parental segments.

Additionally, 23andMe paints your chromosome segments with your ethnic heritage, as shown below.

You can see that my yellow Native American segments appear on chromosomes 1 and 2.

In January 2017, 23andMe introduced their Ancestry Timeline, which I find to be extremely misleading and inaccurate. On my timeline, shown below, they estimate that my most recent British and Irish ancestor was found in my tree between 1900 and 1930 while in reality my most recent British/Irish individual found in my tree was born in England in 1759.

I do not view 23andMe’s Ancestry Timeline as a benefit to the genealogist, having found that it causes people to draw very misleading conclusions, even to the point of questioning their parentage based on the results. I wrote about their Ancestry Timeline here.

Ethnicity Summary

All three vendors provide both ethnicity percentage estimates and maps. All three vendors provide additional tools and features relevant to ethnicity. Vendors also provide matching to other people which may or may not be of interest to people who test only for ethnicity. “Who you are” only begins with ethnicity estimates.

DNA test costs are similar, although the Family Tree DNA test is less at $89. All three vendors have sales from time to time.

Adoption and Parental Identity

DNA testing is extremely popular among adoptees and others in search of missing parents and grandparents.

The techniques used for adoption and parental search are somewhat different than those used for more traditional genealogy, although non-adoptees may wish to continue to read this section because many of the features that are important to adoptees are important to other testers as well.

Adoptees often utilize autosomal DNA somewhat differently than traditional genealogists by using a technique called mirror trees. In essence, the adoptee utilizes the trees posted online of their closest DNA matches to search for common family lines within those trees. The common family lines will eventually lead to the individuals within those common trees that are candidates to be the parents of the searcher.

Here’s a simplified hypothetical example of my tree and a first cousin adoptee match.

The adoptee matches me at a first cousin level, meaning that we share at least one common grandparent – but which one? Looking at other people the adoptee matches, or the adoptee and I both match, we find Edith Lore (or her ancestors) in the tree of multiple matches. Since Edith Lore is my grandmother, the adoptee is predicted to be my first cousin, and Edith Lore’s ancestors appear in the trees of our common matches – that tells us that Edith Lore is also the (probable) grandmother of the adoptee.

Looking at the possibilities for how Edith Lore can fit into the tree of me and the adoptee, as first cousins, we fine the following scenario.

Testing the known child of daughter Ferverda will then provide confirmation of this relationship if the known child proves to be a half sibling to the adoptee.

Therefore, close matches, the ability to contact matches and trees are very important to adoptees. I recommend that adoptees make contact with www.dnaadoption.com. The volunteers there specialize in adoptions and adoptees, provide search angels to help people and classes to teach adoptees how to utilize the techniques unique to adoption search such as building mirror trees.

For adoptees, the first rule is to test with all 3 major vendors plus MyHeritage. Family Tree DNA allows you to test with both 23andMe and Ancestry and subsequently transfer your results to Family Tree DNA, but I would strongly suggest adoptees test on the Family Tree DNA platform instead. Your match results from transferring to Family Tree DNA from other companies, except for MyHeritage, will be fewer and less reliable because both 23andMe and Ancestry utilize different chip technology.

For most genealogists, MyHeritage is not a player, as they have only recently entered the testing arena, have a very small data base, no tools and are having matching issues. I recently wrote about MyHeritage here. However, adoptees may want to test with MyHeritage, or upload your results to MyHeritage if you tested with Family Tree DNA, because your important puzzle-solving match just might have tested there and no place else. You can read about transfer kit compatibility and who accepts which vendors’ tests here.

Adoptees can benefit from ethnicity estimates at the continental level, meaning that regional (within continent) or minority ethnicity should be taken with a very large grain of salt. However, knowing that you have 25% Jewish heritage, for example, can be a very big clue to an adoptee’s search.

Another aspect of the adoptees search that can be relevant is the number of foreign testers. For many years, neither 23andMe, nor Ancestry tested substantially (or at all) outside the US. Family Tree DNA has always tested internationally and has a very strong Jewish data base component.

Not all vendors report X chromosome matches. The X chromosome is important to genetic genealogy, because it has a unique inheritance path. Men don’t inherit an X chromosome from their fathers. Therefore, if you match someone on the X chromosome, you know the relationship, for a male, must be from their mother’s side. For a female, the relationship must be from the mother or the father’s mother’s side. You can read more about X chromosome matching here.

Neither Ancestry nor MyHeritage have chromosome browsers which allow you to view the segments of DNA on which you match other individuals, which includes the X chromosome.

Adoptee Y and Mitochondrial Testing

In addition to autosomal DNA testing, adoptees will want to test their Y DNA (males only) and mitochondrial DNA.

These tests are different from autosomal DNA which tests the DNA you receive from all of your ancestors. Y and mitochondrial DNA focus on only one specific line, respectively. Y DNA is inherited by men from their fathers and the Y chromosome is passed from father to son from time immemorial. Therefore, testing the Y chromosome provides us with the ability to match to current people as well as to use the Y chromosome as a tool to look far back in time. Adoptees tend to be most interested in matching current people, at least initially.

Working with male adoptees, I have a found that about 30% of the time a male will match strongly to a particular surname, especially at higher marker levels. That isn’t always true, but adoptees will never know if they don’t test. An adoptee’s match list is shown at 111 markers, below.

Furthermore, utilizing the Y and mitochondrial DNA test in conjunction with autosomal DNA matching at Family Tree DNA helps narrows possible relatives. The Advanced Matching feature allows you to see who you match on both the Y (or mitochondrial) DNA lines AND the autosomal test, in combination.

Mitochondrial DNA tests the matrilineal line only, as women pass their mitochondrial DNA to all of their children, but only females pass it on. Family Tree DNA provides matching and advanced combination matching/searching for mitochondrial DNA as well as Y DNA. Both genders of children carry their mother’s mitochondrial DNA. Unfortunately, mitochondrial DNA is more difficult to work with because of the surname changes in each generation, but you cannot be descended from a woman, or her direct matrilineal ancestors if you don’t substantially match her mitochondrial DNA.

Some vendors state that you receive mitochondrial DNA with your autosomal results, which is only partly accurate. At 23andMe, you receive a haplogroup but no detailed results and no matching. 23andMe does not test the entire mitochondria and therefore cannot provide either advanced haplogroup placement nor Y or mitochondrial DNA matching between testers.

For additional details on the Y and Mitochondrial DNA tests themselves and what you receive, please see the Genealogy – Y and Mitochondrial DNA section.

Adoption Summary

Adoptees should test with all 4 vendors plus Y and mitochondrial DNA testing.

  • Ancestry – due to their extensive data base size and trees
  • Family Tree DNA – due to their advanced tools, chromosome browser, Y and mitochondrial DNA tests (Ancestry and 23andMe participants can transfer autosomal raw data files and see matches for free, but advanced tools require either an unlock fee or a test on the Family Tree DNA platform)
  • 23andMe – no trees and many people don’t participate in sharing genetic information
  • MyHeritage – new kid on the block, working through what is hoped are startup issues
  • All adoptees should take the full mitochondrial sequence test.
  • Male adoptees should take the 111 marker Y DNA test, although you can start with 37 or 67 markers and upgrade later.
  • Y and mitochondrial tests are only available at Family Tree DNA.

Genealogy – Cousin Matching and Ancestor Search/Verification

People who want to take a DNA test to find cousins, to learn more about their genealogy, to verify their genealogy research or to search for unknown ancestors and break down brick walls will be interested in various types of testing

Test Type Who Can Test
Y DNA – direct paternal line Males only
Mitochondrial DNA – direct matrilineal line Males and Females
Autosomal – all lines Males and Females

Let’s begin with autosomal DNA testing for genealogy which tests your DNA inherited from all ancestral lines.

Aside from ethnicity, autosomal DNA testing provides matches to other people who have tested. A combination of trees, meaning their genealogy, and their chromosome segments are used to identify (through trees) and verify (through DNA segments) common ancestor(s) and then to assign a particular DNA segment(s) to that ancestor or ancestral couple. This process, called triangulation, then allows you to assign specific segments to particular ancestors, through segment matching among multiple people. You then know that when another individual matches you and those other people on the same segment, that the DNA comes from that same lineage. Triangulation is the only autosomal methodology to confirm ancestors who are not close relatives, beyond the past 2-3 generations or so.

All three vendors provide matching, but the tools they include and their user interfaces are quite different. 

Genealogy – Autosomal –  Family Tree DNA

Family Tree DNA entered DNA testing years before any of the others, initially with Y and mitochondrial DNA testing.

Because of the diversity of their products, their website is somewhat busier, but they do a good job of providing areas on the tester’s personal landing page for each of the products and within each product, a link for each feature or function.

For example, the Family Finder test is Family Tree DNA’s autosomal test. Within that product, tools provided are:

  • Matching
  • Chromosome Browser
  • Linked Relationships
  • myOrigins
  • Ancient Origins
  • Matrix
  • Advanced Matching

Unique autosomal tools provided by Family Tree DNA are:

  • Linked Relationships that allows you to connect individuals that you match to their location in your tree, indicating the proper relationship. Phased Family Matching uses these relationships within your tree to indicate which side of your tree other matches originate from.
  • Phased Family Matching shows which side of your tree, maternal, paternal or both, someone descends from, based on phased DNA matching between you and linked relationship matches as distant as third cousins. This allows Family Tree DNA to tell you whether matches are paternal (blue icon), maternal (red icon) or both (purple icon) without a parent’s DNA. This is one of the best autosomal tools at Family Tree DNA, shown below.

  • In Common With and Not In Common With features allow you to sort your matches in common with another individual a number of ways, or matches not in common with that individual.
  • Filtered downloads provide the downloading of chromosome data for your filtered match list.
  • Stackable filters and searches – for example, you can select paternal matches and then search for a particular surname or ancestral surname within the paternal matches.
  • Common ethnicity matching through myOrigins allows you to see selected groups of individuals who match you and share common ethnicities.
  • Y and mtDNA locations of autosomal matches are provided on your ethnicity map through myOrigins.
  • Advanced matching tool includes Y, mtDNA and autosomal in various combinations. Also includes matches within projects where the tester is a member as well as by partial surname.
  • The matrix tool allows the tester to enter multiple people that they match in order to see if those individuals also match each other. The matrix tool is, in combination with the in-common-with tool and the chromosome browser is a form of pseudo triangulation, but does not indicate that the individuals match on the same segment.

  • Chromosome browser with the ability to select different segment match thresholds to display when comparing 5 or fewer individuals to your results.
  • Projects to join which provide group interaction and allow individuals to match only within the project, if desired.

Genealogy – Autosomal – Ancestry

Ancestry only offers autosomal DNA testing to their customers, so their page is simple and straightforward.

Ancestry is the only testing vendor (other than MyHeritage who is not included in this section) to require a subscription for full functionality, although if you call the Ancestry support line, a minimal subscription is available for $49. You can see your matches without a subscription, but you cannot see your matches trees or utilize other functions, so you will not be able to tell how you connect to your matches. Many genealogists have Ancestry subscriptions, so this is minimally problematic for most people.

However, if you don’t realize you need a subscription initially, the required annual subscription raises the effective cost of the test quite substantially. If you let your subscription lapse, you no longer have access to all DNA features. The cost of testing with Ancestry is the cost of the test plus the cost of a subscription if you aren’t already a subscriber.

This chart, from the Ancestry support center, provides details on which features are included for free and which are only available with a subscription.

Unique tools provided by Ancestry include:

  • Shared Ancestor Hints (green leaves) which indicate a match with whom you share a common ancestor in your tree connected to your DNA, allowing you to display the path of you and your match to the common ancestor. In order to take advantage of this feature, testers must link their tree to their DNA test. Otherwise, Ancestry can’t do tree matching.  As far as I’m concerned, this is the single most useful DNA tool at Ancestry. Subscription required.

  • DNA Circles, example below, are created when several people whose DNA matches also share a common ancestor. Subscription required.

  • New Ancestor Discoveries (NADs), which are similar to Circles, but are formed when you match people descended from a common ancestor, but don’t have that ancestor in your tree. The majority of the time, these NADs are incorrect and are, when dissected and the source can be determined, found to be something like the spouse of a sibling of your ancestor. I do not view NADs as a benefit, more like a wild goose chase, but for some people these could be useful so long as the individual understands that these are NOT definitely ancestors and only hints for research.

  • Ancestry uses a proprietary algorithm called Timber to strip DNA from you and your matches that they consider to be “too matchy,” with the idea that those segments are identical by population, meaning likely to be found in large numbers within a population group – making them meaningless for genealogy. The problem is that Timber results in the removal of valid segments, especially in endogamous groups like Acadian families. This function is unique to Ancestry, but many genealogists (me included) don’t consider Timber a benefit.
  • Genetic Communities shows you groups of individuals with whom your DNA clusters. The trees of cluster members are then examined by Ancestry to determine connections from which Genetic Communities are formed. You can filter your DNA match results by Genetic Community.

Genealogy – Autosomal – 23and Me

Unfortunately, the 23andMe website is not straightforward or intuitive. They have spent the majority of the past two years transitioning to a “New Experience” which has resulted in additional confusion and complications when matching between people on multiple different platforms. You can take a spin through the New Experience by clicking here.

23andMe requires people to opt-in to sharing, even after they have selected to participate in Ancestry Services (genealogy) testing, have opted-in previously and chosen to view their DNA Relatives. Users on the “New Experience” can then either share chromosome data and results with each other individually, meaning on a one by one basis, or globally by a one-time opt-in to “open sharing” with matches. If a user does not opt-in to both DNA Relatives and open sharing, sharing requests must be made individually to each match, and they must opt-in to share with each individual user. This complexity and confusion results in an approximate sharing rate of between 50 and 60%. One individual who religiously works their matches by requesting sharing now has a share rate of about 80% of their matches in the data base who HAVE initially selected to participate in DNA Relatives. You can read more about the 23andMe experience at this link.

Various genetic genealogy reports and tools are scattered between the Reports and Tools tabs, and within those, buried in non-intuitive locations. If you are going to utilize 23andMe for matching and genealogy, in addition to the above link, I recommend Kitty Cooper’s blogs about the new DNA Relatives here and on triangulation here. Print the articles, and use them as a guide while navigating the 23andMe site.

Note that some screens (the Tools, DNA Relatives, then DNA tab) on the site do not display/work correctly utilizing Internet Explorer, but do with Edge or other browsers.

The one genealogy feature unique to 23andMe is:

  • Triangulation at 23andMe allows you to select a specific match to compare your DNA against. Several pieces of information will be displayed, the last of which, scrolling to the bottom, is a list of your common relatives with the person you selected.

In the example below, I’ve selected to see the matches I match in common with known family member, Stacy Den (surnames have been obscured for privacy reasons.)  Please note that the Roberta V4 Estes kit is a second test that I took for comparison purposes when the new V4 version of 23andMe was released.  Just ignore that match, because, of course I match myself as a twin.

If an individual does not match both you and your selected match, they will not appear on this list.

In the “relatives in common” section, each person is listed with a “shared DNA” column. For a person to be shown on this “in common” list, you obviously do share DNA with these individuals and they also share with your match, but the “shared DNA” column goes one step further. This column indicates whether or not you and your match both share a common DNA segment with the “in common” person.

I know this is confusing, so I’ve created this chart to illustrate what will appear in the “Shared DNA” column of the individuals showing on the list of matches, above, shared between me and Stacy Den.

Clicking on “Share to see” sends Sarah a sharing request for her to allow you to see her segment matches.

Let’s look at an example with “yes” in the Shared DNA column.

Clicking on the “Yes” in the Shared DNA column of Debbie takes us to the chromosome browser which shows both your selected match, Stacy in my case, and Debbie, the person whose “yes” you clicked.

All three people, meaning me, Stacy and Debbie share a common DNA segment, shown below on chromosome 17.

What 23andMe does NOT say is that these people. Stacy and Debbie, also match each other, in addition to matching me, which means all three of us triangulate.

Because I manage Stacy’s kit at 23andMe, I can check to see if Debbie is on Stacy’s match list, and indeed, Debbie is on Stacy’s match list and Stacy does match both Debbie and me on chromosome 17 in exactly the same location shown above, proving unquestionably that the three of us all match each other and therefore triangulate on this segment. In our case, it’s easy to identify our common relative whose DNA all 3 of us share.

Genealogy – Autosomal Summary

While all 3 vendors offer matching, their interfaces and tools vary widely.

I would suggest that Ancestry is the least sophisticated and has worked hard to make their tools easy for the novice working with genetic genealogy. Their green leaf DNA+Tree Matching is their best feature, easy to use and important for the novice and experienced genealogist alike.  Now, if they just had that chromosome browser so we could see how we match those people.

Ancestry’s Circles, while a nice feature, encourage testers to believe that their DNA or relationship is confirmed by finding themselves in a Circle, which is not the case.

Circles can be formed as the result of misinformation in numerous trees. For example, if I were to inaccurately list Smith as the surname for one of my ancestor’s wives, I would find myself in a Circle for Barbara Smith, when in fact, there is absolutely no evidence whatsoever that her surname is Smith. Yet, people think that Barbara Smith is confirmed due to a Circle having been formed and finding themselves in Barbara Smith’s Circle. Copying incorrect trees equals the formation of incorrect Circles.

It’s also possible that I’m matching people on multiple lines and my DNA match to the people in any given Circle is through another common ancestor entirely.

A serious genealogist will test minimally at Ancestry and at Family Tree DNA, who provides a chromosome browser and other tools necessary to confirm relationships and shared DNA segments.

Family Tree DNA is more sophisticated, so consequently more complex to use.  They provide matching plus numerous other tools. The website and matching is certainly friendly for the novice, but to benefit fully, some experience or additional education is beneficial, not unlike traditional genealogy research itself. This is true not just for Family Tree DNA, but GedMatch and 23andMe who all three utilize chromosome browsers.

The user will want to understand what a chromosome browser is indicating about matching DNA segments, so some level of education makes life a lot easier. Fortunately, understanding chromosome browser matching is not complex. You can read an article about Match Groups and Triangulation here. I also have an entire series of Concepts articles, Family Tree DNA offers a webinar library, their Learning Center and other educational resources are available as well.

Family Tree DNA is the only vendor to provide Phased Family Matches, meaning that by connecting known relatives who have DNA tested to your tree, Family Tree DNA can then identify additional matches as maternal, paternal or both. This, in combination with pseudo-phasing are very powerful matching tools.

23andMe is the least friendly of the three companies, with several genetic genealogy unfriendly restrictions relative to matching, opt-ins, match limits and such. They have experienced problem after problem for years relative to genetic genealogy, which has always been a second-class citizen compared to their medical research, and not a priority.

23andMe has chosen to implement a business model where their customers must opt-in to share segment information with other individuals, either one by one or by opting into open sharing. Based on my match list, roughly 60% of my actual DNA matches have opted in to sharing.

Their customer base includes fewer serious genealogists and their customers often are not interested in genealogy at all.

Having said that, 23andMe is the only one of the three that provides actual triangulated matches for users on the New Experience and who have opted into sharing.

If I were entering the genetic genealogy testing space today, I would test my autosomal DNA at Ancestry and at Family Tree DNA, but I would probably not test at 23andMe. I would test both my Y DNA (if a male) and mitochondrial at Family Tree DNA.

Thank you to Kitty Cooper for assistance with parent/child matching and triangulation at 23andMe.

Genealogy – Y and Mitochondrial DNA

Two indispensable tools for genetic genealogy that are often overlooked are Y and mitochondrial DNA.

The inheritance path for Y DNA is shown by the blue squares and the inheritance path for mitochondrial DNA is shown by the red circles for the male and female siblings shown at the bottom of the chart.

Y-DNA Testing for Males

Y DNA is inherited by males only, from their father. The Y chromosome makes males male. Women instead inherit an X chromosome from their father, which makes them female. Because the Y chromosome is not admixed with the DNA of the mother, the same Y chromosome has been passed down through time immemorial.

Given that the Y chromosome follows the typical surname path, Y DNA testing is very useful for confirming surname lineage to an expected direct paternal ancestor. In other words, an Estes male today should match, with perhaps a few mutations, to other descendants of Abraham Estes who was born in 1647 in Kent, England and immigrated to the colony of Virginia.

Furthermore, that same Y chromosome can look far back in time, thousands of years, to tell us where that English group of Estes men originated, before the advent of surnames and before the migration to England from continental Europe. I wrote about the Estes Y DNA here, so you can see an example of how Y DNA testing can be used.

Y DNA testing for matching and haplogroup identification, which indicates where in the world your ancestors were living within the past few hundred to few thousand years, is only available from Family Tree DNA. Testing can be purchased for either 37, 67 or 111 markers, with the higher marker numbers providing more granularity and specificity in matching.

Family Tree DNA provides three types of Y DNA tests.

  • STR (short tandem repeat) testing is the traditional Y DNA testing for males to match to each other in a genealogically relevant timeframe. These tests can be ordered in panels of 37, 67 or 111 markers and lower levels can be upgraded to higher levels at a later date. An accurate base haplogroup prediction is made from STR markers.
  • SNP (single nucleotide polymorphism) testing is a different type of testing that tests single locations for mutations in order to confirm and further refine haplogroups. Think of a haplogroup as a type of genetic clan, meaning that haplogroups are used to track migration of humans through time and geography, and are what is utilized to determine African, European, Asian or Native heritage in the direct paternal line. SNP tests are optional and can be ordered one at a time, in groups called panels for a particular haplogroup or a comprehensive research level Y DNA test called the Big Y can be ordered after STR testing.
  • The Big Y test is a research level test that scans the entire Y chromosome to determine the most refined haplogroup possible and to report any previously unknown mutations (SNPs) that may define further branches of the Y DNA tree. This is the technique used to expand the Y haplotree.

You can read more about haplogroups here and about the difference between STR markers and SNPs here, here and here.

Customers receive the following features and tools when they purchase a Y DNA test at Family Tree DNA or the Ancestry Services test at 23andMe. The 23andMe Y DNA information is included in their Ancestry Services test. The Family Tree DNA Y DNA information requires specific tests and is not included in the Family Finder test. You can click here to read about the difference in the technology between Y DNA testing at Family Tree DNA and at 23andMe. Ancestry is not included in this comparison because they provide no Y DNA related information.

Mitochondrial DNA Testing for Everyone

Mitochondrial DNA is contributed to both genders of children by mothers, but only the females pass it on. Like the Y chromosome, mitochondrial DNA is not admixed with the DNA of the other parent. Therefore, anyone can test for the mitochondrial DNA of their matrilineal line, meaning their mother’s mother’s mother’s lineage.

Matching can identify family lines as well as ancient lineage.

You receive the following features and tools when you purchase a mitochondrial DNA test from Family Tree DNA or the Ancestry Services test from 23andMe. The Family Tree DNA mitochondrial DNA information requires specific tests and is not included in the Family Finder test. The 23andMe mitochondrial information is provided with the Ancestry Services test. Ancestry is omitted from this comparison because they do not provide any mitochondrial information.

Overall Genealogy Summary

Serious genealogists should test with at least two of the three major vendors, being Family Tree DNA and Ancestry, with 23andMe coming in as a distant third.

No genetic genealogy testing regimen is complete without Y and mitochondrial DNA for as many ancestral lines as you can find to test. You don’t know what you don’t know, and you’ll never know if you don’t test.

Unfortunately, many people, especially new testers, don’t know Y and mitochondrial DNA testing for genetic genealogy exists, or how it can help their genealogy research, which is extremely ironic since these were the first tests available, back in 2000.

You can read about finding Y and mitochondrial information for various family lines and ancestors and how to assemble a DNA Pedigree Chart here.

You can also take a look at my 52 Ancestors series, where I write about an ancestor every week. Each article includes some aspect of DNA testing and knowledge gained by a test or tests, DNA tool, or comparison. The DNA aspect of these articles focuses on how to use DNA as a tool to discover more about your ancestors.

Testing for Medical/Health or Traits

The DTC market also includes health and medical testing, although it’s not nearly as popular as genetic genealogy.

Health/medical testing is offered by 23andMe, who also offers autosomal DNA testing for genealogy.

Some people do want to know if they have genetic predispositions to medical conditions, and some do not. Some want to know if they have certain traits that aren’t genealogically relevant, but might be interesting – such as whether they carry the Warrior gene or if they have an alcohol flush reaction.

23andMe was the first company to dip their toes into the water of Direct to Consumer medical information, although they called it “health,” not medicine, at that time. Regardless of the terminology, information regarding Parkinson’s and Alzheimer’s, for example, were provided for customers. 23andMe attempted to take the raw data and provide the consumer with something approaching a middle of the road analysis, because sometimes the actual studies provide conflicting information that might not be readily understood by consumers.

The FDA took issue with 23andMe back in November of 2013 when they ordered 23andMe to discontinue the “health” aspect of their testing after 23andMe ignored several deadlines. In October 2015, 23andMe obtained permission to provide customers with some information, such as carrier status, for 36 genetic disorders.

Since that time, 23andMe has divided their product into two separate tests, with two separate prices. The genealogy only test called Ancestry Service can be purchased separately for $99, or the combined Health + Ancestry Service for $199.

If you are interested in seeing what the Health + Ancestry test provides, you can click here to view additional information.

However, there is a much easier and less expensive solution.

If you have taken the autosomal test from 23andMe, Ancestry or Family Tree DNA, you can download your raw data file from the vendor and upload to Promethease to obtain a much more in-depth report than is provided by 23andMe, and much less expensively – just $5.

I reviewed the Promethease service here. I found the Promethease reports to be very informative and I like the fact that they provide information, both positive and negative for each SNP (DNA location) reported. Promethease avoids FDA problems by not providing any interpretation or analysis, simply the data and references extracted from SNPedia for you to review.

I would be remiss if I didn’t mention that you should be sure you really want to know before you delve into medical testing. Some mutations are simply indications that you could develop a condition that you will never develop or that is not serious. Other mutations are not so benign. Promethease provides this candid page before you upload your data.

Different files from different vendors provide different results at Promethease, because those vendors test different SNP locations in your DNA. At the Promethease webpage, you can view examples.

Traits

Traits fall someplace between genealogy and health. When you take the Health + Ancestry test at 23andMe, you do receive information about various traits, as follows:

Of course, you’ll probably already know if you have several of these traits by just taking a look in the mirror, or in the case of male back hair, by asking your wife.

At Family Tree DNA, existing customers can order tests for Factoids (by clicking on the upgrade button), noted as curiosity tests for gene variants.

Family Tree DNA provides what I feel is a great summary and explanation of what the Factoids are testing on their order page:

“Factoids” are based on studies – some of which may be controversial – and results are not intended to diagnose disease or medical conditions, and do not serve the purpose of medical advice. They are offered exclusively for curiosity purposes, i.e. to see how your result compared with what the scientific papers say. Other genetic and environmental variables may also impact these same physiological characteristics. They are merely a conversational piece, or a “cocktail party” test, as we like to call it.”

Test Price Description
Alcohol Flush Reaction $19 A condition in which the body cannot break down ingested alcohol completely. Flushing, after consuming one or two alcoholic beverages, includes a range of symptoms: nausea, headaches, light-headedness, an increased pulse, occasional extreme drowsiness, and occasional skin swelling and itchiness. These unpleasant side effects often prevent further drinking that may lead to further inebriation, but the symptoms can lead to mistaken assumption that the people affected are more easily inebriated than others.
Avoidance of Errors $29 We are often angry at ourselves because we are unable to learn from certain experiences. Numerous times we have made the wrong decision and its consequences were unfavorable. But the cause does not lie only in our thinking. A mutation in a specific gene can also be responsible, because it can cause a smaller number of dopamine receptors. They are responsible for remembering our wrong choices, which in turn enables us to make better decisions when we encounter a similar situation.
Back Pain $39 Lumbar disc disease is the drying out of the spongy interior matrix of an intervertebral disc in the spine. Many physicians and patients use the term lumbar disc disease to encompass several different causes of back pain or sciatica. A study of Asian patients with lumbar disc disease showed that a mutation in the CILP gene increases the risk of back pain.
Bitter Taste Perception $29 There are several genes that are responsible for bitter taste perception – we test 3 of them. Different variations of this gene affect ability to detect bitter compounds. About 25% of people lack ability to detect these compounds due to gene mutations. Are you like them? Maybe you don’t like broccoli, because it tastes too bitter?
Caffeine Metabolism $19 According to the results of a case-control study reported in the March 8, 2006 issue of JAMA, coffee is the most widely consumed stimulant in the world, and caffeine consumption has been associated with increased risk for non-fatal myocardial infarction. Caffeine is primarily metabolized by the cytochrome P450 1A2 in the liver, accounting for 95% of metabolism. Carriers of the gene variant *1F allele are slow caffeine metabolizers, whereas individuals homozygous for the *1A/*1A genotype are rapid caffeine metabolizers.
Earwax Type $19 Whether your earwax is wet or dry is determined by a mutation in a single gene, which scientists have discovered. Wet earwax is believed to have uses in insect trapping, self-cleaning and prevention of dryness in the external auditory canal of the ear. It also produces an odor and causes sweating, which may play a role as a pheromone.
Freckling $19 Freckles can be found on anyone no matter what the background. However, having freckles is genetic and is related to the presence of the dominant melanocortin-1 receptor MC1R gene variant.
Longevity $49 Researchers at Harvard Medical School and UC Davis have discovered a few genes that extend lifespan, suggesting that the whole family of SIR2 genes is involved in controlling lifespan. The findings were reported July 28, 2005 in the advance online edition of Science.
Male Pattern Baldness $19 Researchers at McGill University, King’s College London and GlaxoSmithKline Inc. have identified two genetic variants in Caucasians that together produce an astounding sevenfold increase of the risk of male pattern baldness. Their results were published in the October 12, 2008 issue of the Journal of Nature Genetics.
Monoamine Oxidase A (Warrior Gene) $49.50 The Warrior Gene is a variant of the gene MAO-A on the X chromosome. Recent studies have linked the Warrior Gene to increased risk-taking and aggressive behavior. Whether in sports, business, or other activities, scientists found that individuals with the Warrior Gene variant were more likely to be combative than those with the normal MAO-A gene. However, human behavior is complex and influenced by many factors, including genetics and our environment. Individuals with the Warrior Gene are not necessarily more aggressive, but according to scientific studies, are more likely to be aggressive than those without the Warrior Gene variant. This test is available for both men and women, however, there is limited research about the Warrior Gene variant amongst females. Additional details about the Warrior Gene genetic variant of MAO-A can be found in Sabol et al, 1998.
Muscle Performance $29 A team of researchers, led by scientists at Dartmouth Medical School and Dartmouth College, have identified and tested a gene that dramatically alters both muscle metabolism and performance. The researchers say that this finding could someday lead to treatment of muscle diseases, including helping the elderly who suffer from muscle deterioration and improving muscle performance in endurance athletes.
Nicotine Dependence $19 In 2008, University of Virginia Health System researchers have identified a gene associated with nicotine dependence in both Europeans and African Americans.

Many people are interested in the Warrior Gene, which I wrote about here.

At Promethease, traits are simply included with the rest of the conditions known to be associated with certain SNPs, such as baldness, for example, but I haven’t done a comparison to see which traits are included.

 

Additional Vendor Information to Consider

Before making your final decision about which test or tests to purchase, there are a few additional factors you may want to consider.

As mentioned before, Ancestry requires a subscription in addition to the cost of the DNA test for the DNA test to be fully functional.

One of the biggest issues, in my opinion, is that both 23andMe and Ancestry sell customer’s anonymized DNA information to unknown others. Every customer authorizes the sale of their information when they purchase or activate a kit – even though very few people actually take the time to read the Terms and Conditions, Privacy statements and Security documents, including any and all links. This means most people don’t realize they are authorizing the sale of their DNA.

At both 23andMe and Ancestry, you can ALSO opt in for additional non-anonymized research or sale of your DNA, which you can later opt out of. However, you cannot opt out of the lower level sale of your anonymized DNA without removing your results from the data base and asking for your sample to be destroyed. They do tell you this, but it’s very buried in the fine print at both companies. You can read more here.

Family Tree DNA does not sell your DNA or information.

All vendors can change their terms and conditions at any time. Consumers should always thoroughly read the terms and conditions including anything having to do with privacy for any product they purchase, but especially as it relates to DNA testing.

Family Tree DNA archives your DNA for later testing, which has proven extremely beneficial when a family member has passed away and a new test is subsequently introduced or the family wants to upgrade a current test.  Had my mother’s DNA not been archived at Family Tree DNA, I would not have Family Finder results for her today – something I thank Mother and Family Tree DNA for every single day.

Family Tree DNA also accepts transfer files from 23andMe, Ancestry and very shortly, MyHeritage – although some versions work better than others. For details on which companies accept which file versions, from which vendors, and why, please read Autosomal DNA Transfers – Which Companies Accept Which Tests?

If you tested on a compatible version of the 23andMe Test (V3 between December 2010 and November 2013) or the Ancestry V1 (before May 2016) you may want to transfer your raw data file to Family Tree DNA for free and pay only $19 for full functionality, as opposed to taking the Family Finder test. Family Tree DNA does accept later versions of files from 23andMe and Ancestry, but you will receive more matches if you test on the same chip platform that Family Tree DNA utilizes instead of doing a transfer.

Which Test is Best For You?

I hope you now know the answer as to which DNA test is best for you – or maybe it’s multiple tests for you and other family members too!

DNA testing holds so much promise for genealogy. I hesitate to call DNA testing a miracle tool, but it often is when there are no records. DNA testing works best in conjunction with traditional genealogical research.

There are a lot of tests and options.  The more tests you take, the more people you match. Some people test at multiple vendors or upload their DNA to third party sites like GedMatch, but most don’t. In order to make sure you reach those matches, which may be the match you desperately need, you’ll have to test at the vendor where they tested. Otherwise, they are lost to you. That means, of course, that eventually, if you’re a serious genealogist, you’ll be testing at all 3 vendors.  Don’t forget about Y and mitochondrial tests at Family Tree DNA.

Recruit family members to test and reach out to your matches.  The more you share and learn – the more is revealed about your ancestors. You are, after all, the unique individual that resulted from the combination of all of them!
