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!

DNA Results – First Glances at Ethnicity and Matching!

People who have worked with genetic genealogy for a long time often forget what it’s like to be a new person taking a DNA test.

Recently, someone asked me what a tester actually sees after they take a DNA test and their results are ready. Good question, especially for someone trying to decide what might work for them.

I’m going to make this answer very simple. For each of the 4 major vendors, I’m going to show what a customer sees when they first sign in and view their results. Not everything or every tool, just their main page along with the initial matching and ethnicity pages.

Please feel free to share this article with people who are new and might be interested. It’s easy to follow along.

I do want to stress that this is just the beginning, not the end game and that every vendor has much more to offer if you take advantage of their tools.

Best of all, it’s so much FUN to learn about your heritage and your ancestry, plus meeting cousins and family members you may not have known that you had.

I’ve been gifted with photos of my grandparents and great-grandparents that I had no idea existed before meeting new family members.

I hope that all the new testers will become excited and that their results are just a tiny first step!

The Vendors

I’m going to take a look at:

Each vendor offers DNA matching to others in their database, plus ethnicity estimates. Yes, ethnicity is only an estimate.

Family Tree DNA

Family Tree DNA was the first and still the only genetic genealogy testing company to offer a full range of DNA testing products, launching in the year 2000. Today they stand out as the “science company,” offering both Y and mitochondrial DNA testing in addition to their Family Finder test which is comparable with the tests offered by Ancestry, 23andMe and MyHeritage.

Your personal page at Family Tree DNA shows the following tools for the Family Finder test.

Glances Family Tree DNA home

The two options we’ll look at today are your Matches and myOrigins, which is your ethnicity estimate.

Click on Matches to view whose DNA matches you. In my case, on the page below, you can see that I have a total of 4610 matches, of which 986 have been assigned to my paternal side, 842 to my maternal side, and 4 to both sides. In my case, the 4 assigned to both sides are my children and grandchildren, which makes perfect sense,

Glances Family Tree DNA matches

You can click to enlarge this graphic.

The green box above the matches indicates additional tools which provide information such as who I match in common with another person. I can see, for example, who I match in common with a first cousin which is very helpful in determining which ancestor those matches are related through.

The red box and circle show information provided to me about each match.

Family Tree DNA is able to divide my matches into “Maternal,” “Paternal” and “Both” buckets because they encourage me to link DNA matches on my tree. This means that I connect my mother to her location on my tree so that Family Tree DNA knows that people that match Mother and me both are related on my mother’s side of the tree.

Your matches don’t have to be your parents for linking to work. The more people you link, the more matches Family Tree DNA can put into buckets for you, especially if your parents aren’t available to test. Plus, your aunts and uncles inherited parts of your grandparent’s DNA that your parents didn’t, so they are super important!

Figuring out which side your matches come from, and which ancestor is first step in genetic genealogy!

You can see, above, that my mother is “assigned” on my maternal side and my son matches me on both.

“Bucketing” is a great, innovative feature. But there’s more.

The tan rounded rectangle includes ancestral surnames, with the ones that you and your match have in common shown in bold.

Based on the amount of DNA that I share with a match, and other scientific calculations, a relationship range is calculated, with the linked relationship reflecting where I’ve put that person on my tree.

If your match has uploaded or created a tree, you can view their tree (if they share) by clicking on the little blue pedigree icon, above, circled in tan between the two arrows.

Glances Family Tree DNA tree

Here’s my tree with my family members who have DNA tested attached in the proper places in my tree. Of course, there are a lot more connected people that I’m not showing in this view.

Advanced features include tools like a matching matrix and a chromosome browser where you can view the segments that actually match.

Family Tree DNA Ethnicity

To view your ethnicity estimate, click on myOrigins and you’ll see the following, along with people you match in the various regions if they have given permission for that information to be shared with their matches:

MyHeritage

MyHeritage has penetrated the European market quite well, so if your ancestors are from the US or Europe, MyHeritage is a wonderful resource. They offer both DNA testing and records via subscription, combining genetic matches and genealogical records into a powerful tool.

Glances MyHeritage home

At MyHeritage, when you sign in, the DNA tab is at the top.

Clicking on DNA Matches shows you the following match list:

Glances MyHeritage matches

To review all of the information provided for each match, meaning who they match in common with you, their ancestral surnames, their tree and matching details, you’ll click on “Review DNA Match.”

MyHeritage provides a special tool called Theories of Family Relativity which connects you with others and your common ancestors. In essence, MyHeritage uses DNA, trees and records to weave together at least some of your family lines, quite accurately.

Here’s a simple example where MyHeritage has figured out that one of the testers is my niece and has drawn our connection for us.

Theory match 2

Theories of Family Relativity is a recently released world-class tool, easy to use but can solve very complex problems. I wrote about it here.

Advanced DNA tools include a chromosome browser and triangulation, a feature which shows you when three people match on a common segment, indicating genetically that you all 3 share a common ancestor from whom you inherited that common piece of DNA.

MyHeritage Ethnicity

To view your ethnicity estimate at MyHeritage, simply click on Ethnicity Estimate on the menu.

Glances MyHeritage ethnicity.png

23andMe

23andMe is better known for their health offering, although they were the first commercial company to offer autosomal commercial testing. However, they don’t support trees, which for genealogists are essential. Furthermore, they limit the number of your matches to your 2000 closest matches, but if some of those people don’t choose to be included in matching, they are subtracted from your 2000 total allowed. Due to this, I have only 1501 matches, far fewer matches at 23andMe than at any of the other vendors.

Glances 23andMe home

At 23andMe when you sign on, under the Ancestry tab you’ll see DNA Relatives which are your matches and Ancestry Composition which is your ethnicity estimate.

Glances 23andMe matches

While you don’t see all of the information on this primary DNA page that you do with the other vendors, with the unfortunate exception of trees, it’s there, just not on the initial display.

23andMe also provides some advanced tools such as a chromosome browser and triangulation.

23andMe Ethnicity

What 23andMe does exceptionally well is ethnicity estimates.

To view your ethnicity at 23andMe, click on Ancestry Composition.

Glances 23andMe ethnicity

23andMe refines your ethnicity estimates if your parents have tested and shows you a composite of your ethnicity with your matches. However, I consider their ethnicity painting of your chromosomes to be their best feature.

Glances 23andMe chromosome painting

You can see, in my case, the two Native American segments on chromosomes 1 and 2, subsequently proven to be accurate via documentation along with Y and mitochondrial DNA tests at Family Tree DNA. The two chromosomes shown don’t equate necessarily to maternal and paternal.

I can download this information into a spreadsheet, meaning that I can then compare matches at other companies to these ethnicity segments on my mother’s side. If my matches share these segments, they too descend from our common Native American ancestor. How cool is that!!!

Ancestry

Ancestry’s claim to fame is that they have the largest DNA database for autosomal results. Because of that, you’ll have more matches at Ancestry, but if you’re a genealogist or someone seeking an unknown family member, the match you NEED might just be found in one of the other databases, so don’t assume you can simply test at one company and find everything you need.

You don’t know what you don’t know.

Glances Ancestry home

At Ancestry, when you sign on, you’ll see the DNA tab. Click on DNA Story.

Glances Ancestry DNA tab

Scrolling past some advertising, you’ll see DNA Story, which is your Ethnicity Estimate and DNA Matches.

ThruLines, at right, is a tool similar to MyHeritage’s Theories of Family Relativity, but not nearly as accurate. However, Thrulines are better than they were when first released in February. I wrote about ThruLines here.

Glances Ancestry matches

Clicking on DNA Matches shows me information about my matches, in red, their trees or lack thereof in green, and information I can enter including ways to group my matches, in tan.

One of Ancestry’s best features is the green leaf, at the bottom in the green box, accompanied by the smiley face (that I added.) That means that this match’s tree indicates that we have a common ancestor. However, the smiley face is immediately followed by the sad face when I noticed the little lock, which means their tree is private and they aren’t sharing it with me.

If DNA testers forget and don’t connect their tree to their DNA results, you’ll see “unlinked tree.”

Like other vendors, Ancestry offers other tools as well, including the ability to define your own colored tags. You can see that I’ve tagged the matches at far right in the gold box with the little colored dots. I was able to define those dots and they have meanings such as common ancestor identified, messaged, etc.

Ancestry Ethnicity

To view your ethnicity estimate, click on “View Your DNA Story.”

Glances Ancestry ethnicity

You’ll see your ethnicity estimate and communities of matches that Ancestry has defined. By clicking on the community, you can see the ancestors in your tree that plot on the map into that community, along with a timeline. Seeing a community doesn’t necessarily mean your ancestor lived there, but that you match a group of people who are from that community.

Sharing Information

You might be thinking to yourself that it would be a lot easier if you could just test at one vendor and share the results in the other databases. Sometimes you can.

There is a central open repository at GedMatch, but clearly not everyone uploads there, so you still need to be in the various vendors’ data bases. GedMatch doesn’t offer testing, but offers additional tools, flexibility and open access not provided by the testing vendors.

Of these four vendors, Family Tree DNA and MyHeritage accept transferred files from other vendors, while Ancestry and 23andMe do not.

Transferring

If you’re interested in transferring, meaning downloading your results from one vendor and uploading to another, I wrote a series of how-to transfer articles here:

Enjoy your new matches and have fun!

Identifying Unknown Parents and Individuals Using DNA Matching

There have been a lot of questions recently about the methodology used by people searching for unknown parents and other unidentified individuals. I covered this technique in concept recently at a conference as part of an overview presentation. In this article, I’m addressing only this topic and in more detail.

What is the methodology that genealogists use to identify unknown parents? It’s exactly the same process used to identify unknown Does, meaning unidentified bodies as well as violent criminals who have left DNA, such as blood or semen, at a crime scene.

How is Identifying Unknown Individuals Different from Genealogy?

Genealogists are interested in discovering their ancestors. Generally, genealogists know who their parents are and most of the time, their grandparents as well. Not very many people can tell you the names of their great-grandparents off the top of their head – not unless they ARE genealogists😊

Genealogists interview family members and access family sources, such as photos, Bibles, boxes of memorabilia and often extend their family another generation or two using these resources. Then, to gather additional information, genealogists turn to publicly available sources such as:

Constructing a Tree

Genealogists utilize software to create trees of their ancestors, either on their own computers with software such as Family Tree Maker, Legacy, RootsMagic or the free tree building software from MyHeritage. They then either synchronize or duplicate their tree on the public sites mentioned above which provide functionality such as “hints” that point to documents relevant to the ancestors in their tree. Additionally, they can access the trees of other genealogists who are researching the same ancestors. This facilitates the continued growth of their tree by adding ancestors and extending the tree back generations.

While tree-building is the goal of genealogists, the trees they build are important tools for people seeking to identify unknown individuals.

The Tree

Generations tree

In my tree, shown in the format of a pedigree chart, above, you can see that I’ve identified all 16 of my great-great-grandparents. In reality, because I’ve been a genealogist for decades, I’ve identified many more of my ancestors which are reflected in my tree on my computer and in my trees at both Ancestry and MyHeritage where I benefit from hints and DNA matches.

Genealogical pedigree charts are typically represented with the “home person,” me, in this case at the base with my ancestors branching out behind them like a lovely peacock’s tail.

While I’m looking for distant ancestors, adoptees and others seeking the identities of contemporary people are not looking back generations, but seek to identify contemporary generations, meaning people who are alive or lived very recently, typically within a generation.

Enter the world of genetics and DNA matching.

Genetics, The Game Changing Tool

Before the days of DNA testing, adoptees could only hope that someone knew the identify of their biological parents, or that their biological parents registered with a reunion site, or that their court records could be opened.

DNA testing changed all of that, because people can now DNA test and find their close relatives. As more people test, the better the odds of actually having a parent or sibling match, or perhaps a close relative like an aunt, uncle or first cousin. My closest relative that has tested that I didn’t know was testing is my half-sister’s daughter.

You share grandparents with your first cousin, and since you only have 4 grandparents, it’s not terribly difficult to figure out which set of grandparents you connect to through that first cousin – especially given the size of the databases and the number of matches that people have today.

The chart below shows my matches as of June 2019.

Vendor

Total Matches

4,609

18

MyHeritage

9,644

14

23andMe

1,501

5

Ancestry

80,151

8

You can see that I have a total of 45 close matches, although some of those matches are duplicates of each other. However, each database has some people that are only in that database and have not tested at other companies or transferred to other databases.

Situations like this are exactly why people who are searching for unknown family members take DNA tests at all 4 of the vendors.

Stories were once surprising about people who tested and either discover a previously unknown close relative, or conversely discovered that they are not related to someone who they initially believed they were. Today these occurrences are commonplace.

Matches

If you’re searching for an unknown parent or close relative, you just might be lucky to receive a parental, sibling, half-sibling or uncle/aunt match immediately.

An estimated relationship range is provided by all vendors based on the amount of DNA that the tester shares with their match.

Generations Family Tree DNA matches

My mother’s match page at Family Tree DNA is shown above. You can see that I’m Mother’s closest match. My known half brother did not test before he passed away, and mother’s parents are long deceased, so my mother should NEVER have another match this close.

So, who is that person in row 2 that is also predicted to be a mother or daughter? I took a test at Ancestry and uploaded my results to Family Tree DNA for research purposes, so this is actually my own second kit, but for example purposes, I’ve renamed myself “Example Adoptee.” Judging from the photo here, apparently my “adopted” sibling was a twin😊

If the adoptee tested at Family Tree DNA, she would immediately see a sibling match (me) and a parent match (Mom.) A match at that cM (centiMorgan) level can only be a parent or a child, and the adoptee knows whether she has a child or not.

Let’s look at a more distant example, which is probably more “typical” than immediately finding a parent match.

Let’s say that the “male adoptee” at the bottom in the red box is also searching for his birth family. He matches my mother at the 2nd-3rd cousin level, so someplace in her tree are his ancestors too.

People who have trees are shown with gold boxes around the tiny pedigree icons, because they literally are trees of gold.

Because of Family Tree DNA’s “bucketing” tool, the software has already told my Mother that the male adoptee is a match on her father’s side of her tree. The adoptee can click on the little pedigree icon to view the trees of his matches to view their ancestors, then engage in what is known as “tree triangulation” with his other close matches.

From the Perspective of the Adoptee

An adoptee tests not knowing anything about their ancestors.

Generations adoptee

When their results come back, the adoptee, in the red box in the center, hoping to identify their biological parents, discovers that their closest matches are the testers in the pink and blue ovals.

The adoptee does NOT know that these people are related to each other at this point, only that these 7 people are their closest matches on their match list.

The adoptee has to put the rest of the story together like a puzzle.

Who Matches Each Other?

In our scenario, test takers 2, 3 and 8 don’t match the adoptee, so the adoptee will never know they tested and vice versa. Everyone at a second cousin level will match each other, but only some people will match at more distant relationships, according to statistics published by 23andMe:

Relationship Level

Percentage of People Who Match

Parents, siblings, aunts, uncles, half siblings, half aunts/uncles and 1st cousins

2nd cousins

>99%

3rd cousins

90%

4th cousins

45%

5th cousins

15%

6th cousins and more distant

<5%

You can view a detailed chart with additional relationships here.

Tree Triangulation

By looking at the individual trees of test taker 1, 4 and 5 whom they match, the adoptee notices that John and Jane Doe are common ancestors in the trees of all 3 test takers. The adoptee may also use “in common with” tools provided by each vendor to see who they match “in common with” another tester. In this case, let’s say that test taker 1, 4 and 5 also match each other, so the adoptee would also make note of that, inferring correctly that they are members of the same family.

The goal is to identify a common ancestor of a group of matches in order to construct the ancestor’s tree, not a pedigree chart backwards in time, as with genealogy, but to construct a descendants’ tree from the ancestral couple to the current day, as completely as possible. After all, the goal is to identify the parent of the adoptee who descends from the common ancestor.

Generations adoptee theory

In this case, the adoptee realized that the pink test takers descended from John and Jane Doe, and the blue test takers descended from Walter and Winnie Smith, and constructed descendant trees of both couples.

The adoptee created a theory, based on the descendants of these two ancestral couples, incorporating other known facts, such as the year when the adoptee was born, and where.

In our example, the adoptee discovered that John and Jane Doe had another daughter, Juanita, whose descendants don’t appear to have tested, and that Juanita had a daughter who was in the right place at the right time to potentially be the mother of the adoptee.

Conversely, Walter and Winnie Smith had a son whose descendants also appear to have not tested, and he had a son who lived in the same place as Juanita Doe. In other words, age, opportunity and process of elimination all play a role in addition to DNA matches. DNA is only the first hint that must be followed up by additional research.

At this point, if the adoptee has taken either Y or mitochondrial DNA testing, those results can serve to either include or exclude some candidates at Family Tree DNA. For example, if the adoptee was a male and matched the Y DNA of the Smith line, that would be HUGE hint.

From this point on, an adoptee can either wait for more people to test or can contact their matches hoping that the matches will have information and be helpful. Keep in mind that all the adoptee has is a theory at this point and they are looking to refine their theory or create a new one and then to help narrow their list of parent candidates.

Fortunately, there are tools and processes to help.

What Are the Odds?

One helpful tool to do this is the WATO, What Are the Odds statistical probability tools at DNAPainter.

Using WATO, you create a hypothesis tree as to how the person whose connection you are seeking might be related, plugging them in to different tree locations, as shown below.

Generations WATO

This is not the same example as Smith and Doe, above, but a real family puzzle being worked on by my cousin. Names are blurred for privacy, of course.

Generations WATO2

WATO then provides a statistical analysis of the various options, with only one of the above hypothesis being potentially viable based on the level of DNA matching for the various hypothetical relationships.

DNAPainter Shared cM Tool

If your eyes are glazing over right about now with all of these numbers flying around, you’re not alone.

I’ll distill this process into individual steps to help you understand how this works, and why, starting with another tool provided by DNAPainter, the Shared cM tool that helps you calculate the most likely relationship with another person.

The more closely related you are to a person, the more DNA you will share with them.

DNAPainter has implemented this tool based on the results of Blaine Bettinger’s Shared cM Project where you can enter the amount of DNA that you share with someone to determine the “best fit” relationship, on average, plus the range of expected shared DNA.

Generations DNAPainter Shared cM Project

You, or the test taker, are in the middle and the relationship ranges surround “you.”

For example, you can clearly see that the number of cMs for my Example Adoptee at 3384 is clearly in the Parent or Child range. But wait, it could also be at the very highest end of a half sibling relationship. Other lower cM matches are less specific, so another feature of the DNAPainter tool is a life-saver.

At the top of the page, you can enter the number of matching cMs and the tool will predict the most likely results, based on probability.

Generations 3384

The relationship for 3384 cMs is 100% a parent/child relationship, shown above, but the sibling box is highlighted below because 3384 is the very highest value in the range. This seems to be a slight glitch in the tool. We can summarize by saying that it would be extremely, extremely rare for a 3384 cM match to be a full sibling instead of a parent or child. Hen’s teeth rare.

Generations parent child

Next, let’s look at 226 cM, for our male adoptee which produces the following results:

Generations 226

The following chart graphically shows the possible relationships. The “male adoptee” is actually Mom’s second cousin. This tool is quite accurate.

Generations 226 chart

Now that you’ve seen the tools in action, let’s take a look at the rest of the process.

The Steps to Success

The single biggest predictor of success identifying an unknown person is the number of close matches. Without relatively close matches, the process gets very difficult quickly.

What constitutes a close match and how many close matches do adoptees generally have to work with?

If an adoptee matches someone at a 2nd or 3rd cousin level, what does that really mean to them?

I’ve created the following charts to answer these questions. By the way, this information is relevant to everyone, not just adoptees.

In the chart below, you can view different relationships in the blue legs of the chart descending from the common ancestral couple.

In this example, “You” and the “Other Tester” match at the 4th cousin level sharing 35 cM of DNA. If you look “up” the tree a generation, you can see that the parents of the testers match at the 3rd cousin level and share 74 cM of DNA, the grandparents of the testers match at the 2nd cousin level and share 223 cM of DNA and so forth.

Generations relationship table

In the left column, generations begin being counted with your parents as generation 1. The cumulative number of direct line relatives you have at each generation is shown in the “# Grandparents” column.

Generations relationship levels

Here’s how to read this chart, straight across.

Viewing the “Generation” column, at the 4th generation level, you have 16 great-great-grandparents. Your great-great-grandparent is a first cousin to the the great-great-grandparent of your 4th cousin. Their parents were siblings.

Looking at it this way, it might not seem too difficult to reassemble the descendancy tree of someone 5 generations in the past, but let’s look at it from the other perspective meaning from the perspective of the ancestral couple.

Generations descendants

Couples had roughly 25 years of being reproductively capable and for most of history, birth control was non-existent. If your great-great-great-grandparents, who were born sometime near the year 1800 (the births of mine range from 1785 to 1810) had 5 children who lived, and each of their descendants had 5 children who lived, today each ancestral couple would have 3,125 descendants.

If that same couple had 10 children and 10 lived in each subsequent generation, they would have 100,000 descendants. Accuracy probably lies someplace in-between. That’s still a huge number of descendants for one couple.

That’s JUST for one couple. You have 32 great-great-great-grandparents, or 16 pairs, so multiply 16 times 3,125 for 50,000 descendants or 100,000 times 16 for…are you ready for this…1,600,000 descendants.

Descendants per GGG-grandparent couple at 5 generations Total descendants for 16 GGG-grandparent couples combined
5 children per generation 3,125 50,000
10 children per generation 100,000 1,600,000

NOW you understand why adoptees need to focus on only close matches and why distant matches at the 3rd and 4th cousin level are just too difficult to work with.

By contrast, let’s look at the first cousin row.

Generations descendants 1C.png

At 5 descendants per generation, you’ll have 25 first cousins or 100 first cousins at 10 descendants per generation.

Generations descendants 2C

At second cousins, you’ll have 125 and 1,000 – so reconstructing these trees down to current descendants is still an onerous task but much more doable than from the third or fourth cousin level, especially in smaller families.

The Perfect Scenario

Barring a fortuitous parent or sibling match, the perfect scenario for adoptees and people seeking unknown individuals means that:

  • They have multiple 1st or 2nd cousin matches making tree triangulation to a maternal and paternal group of matches to identify the common ancestors feasible.
  • Their matches have trees that allow the adoptee to construct theories of how they might fit into a family.

Following the two steps above, when sufficient matching and trees have been assembled, the verification steps begin.

  • Adoptees hope that their matches are responsive to communications requesting additional information to either confirm or refute their relationship theory. For example, my mother could tell the male adoptee that he is related on her father’s side of the family based on Family Tree DNA‘s parental “side” assignment. Based on who else the adoptee matches in common with mother, she could probably tell him how he’s related. That information would be hugely beneficial.
  • In a Doe situation where the goal is to identify remains, with a relatively close match, the investigator could contact that match and ask if they know of a missing family member.
  • In a law enforcement situation where strong close-family matches that function as hints lead to potential violent crime suspects, investigators could obtain a piece of trash discarded by the potential suspect to process and compare to the DNA from the crime scene, such as was done in the Golden State Killer case.

If the discarded DNA doesn’t match the crime scene DNA, the person is exonerated as a potential suspect. If the discarded DNA does match the crime scene DNA, investigators would continue to gather non-DNA evidence and/or pick the suspect up for questioning and to obtain a court ordered DNA sample to compare to the DNA from the crime scene in a law enforcement database.

Sometimes DNA is a Waiting Game

I know that on the surface, DNA matching for adoptees and unknown persons sounds simple, and sometimes it is if there is a very close family match.

More often than not, trying to identify unknown persons, especially if the tester doesn’t have multiple close matches is much like assembling a thousand-piece puzzle with no picture on the front of the box.

Sometimes simply waiting for a better match at some point in the future is the only feasible answer. I waited years for my brother, Dave’s family match. You can read his story here and here.

DNA is a waiting game.

Reminder: Ancestry’s DNA Circles Will Vanish July 1 – Act Now to Preserve

Ancestry circle example

This is reminder that Ancestry is permanently removing DNA Circles from customer accounts on July 1st. If you have not recorded the information held in your Circles and New Ancestor Discoveries, if you had any, do that NOW.

There is a misconception that ThruLines, introduced earlier in 2019, is the same thing as Circles, just in a different format. That is NOT accurate. ThruLines is a different tool and provides some of the same information as Circles (and NADs), but not all and the part that’s missing isn’t available elsewhere.

Circles provide you with information about people who match you that share a common ancestor, but they ALSO show you who else has tested and matches the people you match, but not you. That’s valuable information for numerous reasons. It verifies multiple children of that ancestor genetically and provides you with a genetic network to validate the ancestral connection for all of those people.

ThruLines only shows you who you match in the context of an ancestral family, not who else has tested that you don’t match.

In the article, Archive Ancestry DNA Circles and New Ancestor Discoveries Now, I walk you through how to save your information step by step.

If you haven’t preserved your information, do so now before it’s too late.

Using Ancestry’s New Match Grouping Dots aka “MyMatchDots”

I’d like to say that yesterday’s article titled “Using Ancestry’s Tree Tags” was a little test to see if you were paying attention, but it wasn’t.

I conflated two different new features, and today, I’d like to straighten that out.

First, a shout out to Paula Williams for catching this. Thank you.

What Happened?

Flat out – I messed up. Mea culpa.

Ancestry introduced several new beta features at the same time. Cumulatively, it’s a big change. The functionality is interconnected AND they don’t all work reliably or consistently, so it’s more than a little confusing, or at least it obviously was for me. There is also no “i” information button describing the new features or providing instructions. However, I did find information on MyTreeTags in Ancestry Support here and grouping of matches using colored dots here.

Grouping matches using colored dots also doesn’t have a “name” like MyTreeTags, so it was easy to conflate with the tags. I wish they had named the grouping dots something like “MyMatchDots” to clearly differentiate the function from MyTreeTags, especially since they were released at the same time. Therefore, I’m referring to them at “MyMatchDots” because that’s a lot easier than “grouping matches using colored dots.”

I wasn’t just flying blind. I did watch the training video and thought I understood, but clearly I didn’t have all the moving pieces and parts straight. Maybe you don’t either, and this will help.

There is no graceful recovery here, except to apologize and fix the issue by publishing the correct information.

The good news is that I described the functionality of the colored dots for grouping matches (MyMatchDots) accurately.

The bad news is that I called it by the wrong name in the title and I referred to the colored grouping dots as “tags.” Seemed like a perfectly fitting name to me. Somehow, now I need to bleach that out of my mind. MyMatchDots, MyMatchDots, MyMatchDots…

The error, or course, HAD to be obvious AND in the title – a publishing sin that’s simply non-recoverable. Just like the tool you drop will roll to dead center under the table, bed or the vehicle where you can’t possible reach it. In case anyone had any doubt, Murphy lives!

So, from time to time, those of us who publish just get to suck it up and issue a correction. Today it’s my turn. Thank you for your tolerance and understanding.

One positive aspect – I’ve included additional information about MyMatchDots as well, based on questions and comments from the earlier article.

Groups (MyMatchDots) and MyTreeTags – the Difference

There are now two methods of grouping at Ancestry.

Groups (MyMatchDots) – Colored grouping dots that I described in the original article and am republishing below. I have deleted the earlier article with the incorrect title. The instructions for how to use match grouping dots in that article were and are accurate, but I’ve updated here.

MyMatchDots and MyTreeTags are different in that grouping dots (MyMatchDots) allow you to select up to 24 colored dots to append to and tag YOUR DNA MATCHES on your match list.

MyTreeTags – Tree tags allow you to tag people IN YOUR TREE, living or deceased, with predefined or custom tags.

Here’s a quick screenshot of examples of MyTreeTags as part of a new beta Workspace. In the next few days, I’ll publish an article with examples of how to activate and use MyTreeTags and more about the beta Workspace.

MyTreeTags beta workspace

What follows is the re-publication of yesterday’s instructions for defining and using the colored grouping dots, plus, how to sort and filter using the colored groupings (MyMatchDots.)

Using Ancestry’s New Color Grouping Dots (MyMatchDots)

One of Ancestry’s new beta features is their grouping feature using colored dots that’s I’m referring to as MyMatchDots – my name, not theirs. To enable, you need to click on “Extras” on the top black menu bar, then “Ancestry Lab” on the dropdown, then enable both MyTreeTags and New and Improved DNA Matches.

Ancestry lab.png

No, I don’t know what happens if you only enable one of the features, or turn them off and on. These features seem to be pretty tightly coupled. Feel free to experiment, but I haven’t.

Your DNA Matches

Everyone utilizes matching differently, for different purposes. Your goal should be to devise a grouping methodology that will support the way you are using DNA matching.

I’m showing you how I’m utilizing the colored dots for grouping my matches, and why, but your preferred method and mine may not be at all the same.

Next, click on DNA Matches.

Ancestry matches with tags.png

This shows my closest 2nd cousin matches. You’ll notice that many don’t have trees, or have unlinked trees, but since these are second cousin matches, it was relatively easy for me to figure out quickly which lines they descend from based on who I match in common with them. You can see my comments just below “Add/edit groups” and the little colored dots.

The little colored dots (MyMatchDots) are the group identifiers that I’ve added to each match.

By clicking on the “Add/edit groups” to the right of the colored dots, you can view the legend, meaning the groups you’ve defined. This is what you’ll see every time you want to group someone.

Ancestry tags.png

Notice that the first person, which is my own V2 (version 2) kit, is showing with a green dot, meaning I’ve identified the common ancestor. I could select any number of dots that I’ve defined, or I could define more dots by creating a custom group.

Ancestry custom groups.png

You have 24 colors to select from. I know that sounds like a lot, but you’ll need to do some planning.

MyMatchDots Grouping Strategy

I thought about creating a maternal and paternal match group, but that seemed like a waste of colored dots, so for now, I haven’t. The only way I have to identify maternal and paternal at Ancestry, because neither parent is available to test there, is via known ancestors – and that information is immediately evident to me by the comment indicating the common ancestor.

I tried to think about how I would use the colored dots for sorting.

I decided on the stop light analogy. A green dot for “identified ancestor,” yellow for either “probably identified” or darker yellow for “speculative,” and red for “I’m working on this but it’s tough.” In other words, red means not yet identified. No colored dot means I haven’t worked on that match.

I made both “messaged” and “private” both darker red dots, because often those are used together when I have a show stopper. I want to revisit matches in both of those categories, so I’ll want to be able to sort for them to see if:

  • trees have become public
  • more helpful shared matches exist
  • messages have been answered and I didn’t notice

What’s Missing?

Did you notice what’s missing? That little green leaf on your match list indicating that this person is a DNA match AND has a shared ancestor.

Ancestry common ancestors dropdown.png

While Ancestry just recently re-indexed the trees, the Shared Ancestor Hint “Common Ancestors” leaf is still missing on the matches page where it used to be displayed. I’m hopeful that it will be back as an icon on the match list.

Worse yet, when you click on the “Common Ancestors” filter to display only common ancestors, this error message appears.

Ancestry common matches.png

I do have common ancestor matches – 704 of them to be exact.

Let’s hope that this is a temporary glitch that will be fixed soon.

For me, being able to see the green leaf on my full match list is extremely important because I want to be able to quickly discern which of those matches have shared ancestors.

Fortunately, I made a note for each shared ancestor previously identified, so I sorted for “Notes” in order to group appropriately.

Ancestry notes.png

However, if you haven’t already made those notes, then sorting for notes isn’t useful.

If your account displays Common Ancestors when you select that option, skip to the “Ideas for Using MyMatchDot Groups” section of this article.

If your account does NOT display Common Ancestors, read the Work-Around section, next.

Work-Around

Utilizing my “regular” kit, which does NOT have ThruLines because I have two kits attached to “me” on the same tree, I can group by color (as you’ve seen), but Common Ancestors green leaf function is broken.

Utilizing my second kit V2 kit, which DOES have ThruLines, I can click on “704 Shared Ancestor Hints” from my main DNA Summary page or select the “Common Ancestors” dropdown.

Ancestry shared ancestor links.png

This works.

Ancestry common ancestor leaf.png

I understand that you can “force” common ancestors sorting to work on kits without ThruLines by toggling the Beta option for Advanced Matching to off, but after all the work I just did grouping all 704 of my shared matches, I’m not willing to risk losing all of those dots to test this workaround. The Beta “off” or “on” is for the entire account, not for each individual kit on the account.

What I will do, shortly, is to create a “twin” in my tree and connect my kit that doesn’t have ThruLines to that twin so both kits aren’t attached to “me.” That may or may not solve the problem.

If you do NOT have ThruLines yet, and you want to retain any existing New Ancestor Discoveries (NADs), you must do so before you make a change that enables ThruLines, because NADs are gone on my account that HAS ThruLines, but they exist on the account without ThruLines. NADs have not been updated in many months, but that doesn’t mean I don’t want to retain the existing information. I wrote about how to archive both your Circles and NAD information in this article. My account with ThruLines did retain the Circles. You can toggle back and forth from having ThruLines to not having Thrulines to view your NADs, but eventually, I’m sure they will disappear.

Sorting MyMatchDots

Now that you have matches grouped by color, how do you sort for those clusters? On your matches page, the dropdown for “All matches” shows the groups as well as reports how many people are in each group.

Ancestry groups sort

Ideas for MyMatchDot Groups 

I’ve shared my MyMatchDot grouping strategy, but I’ve kind of stumbled around playing with what works and what doesn’t. I’m sure I haven’t thought of everything.

One person mentioned to me that they are using dots to identify Leeds clusters. I wrote about the Leeds Method in this article which includes links to several articles by Dana Leeds who developed the methodology. She has also written this update. I may group based on Leeds clusters as well as the group dots I’ve already defined.

The great news is that you can assign any number of colored dots, through 24, for groups associated with any individual match.

Someone else mentioned that they were initially grouping based on Genetic Affairs clusters, but matches can change clusters, especially if the thresholds change, so that might not be such a good idea.

In the next article, we’ll talk about how to activate and use MyTreeTags.

DNA Testing and Transfers – What’s Your Strategy?

The landscape of genetic genealogy is forever morphing.

I’m providing a quick update as to which vendors support file transfers from which other vendors in a handy matrix.

Come join in the fun!

Testing and Transfer Strategy

Using the following chart, you can easily plan a testing and transfer strategy.

DNA Vendor Transfer Chart 2019

Click on image to enlarge.

Caveats and footnotes as follows:

1. After May 2016, the Ancestry test is only partly compatible, meaning you receive your closest matches (about 20-25% of the total) but won’t receive distant matches due to chip incompatibility. However, beginning in April 2019, when Family Tree DNA implemented the Illumina GSA chip, Ancestry files are receiving all matches.

2. The 23andMe December 2010 (V3) version is fully compatible. December 2013-August 2017 (V4) and August 2017 (V5) tests are partly compatible meaning you receive your closest matches (about 20-25% of the total) but won’t receive distant matches due to chip incompatibility. However, beginning in April 2019, when Family Tree DNA implemented the Illumina GSA chip, 23andMe V4 and V5 files are receiving all matches.
3. GedMatch has been working to resolve autosomal matching issues between vendor’s chips. Patience is a key word.
4. LivingDNA does not yet have full blown matching (I have one match), which has been in the testing phase for months, and has recently changed chip vendors.
5. Customer must extract the file using a file utility before it can be uploaded. LivingDNA indicates that they are working on a simpler solution.
6. Files transferred to LivingDNA must be in build 37 format.
4-12-2019 update – please note that MyHeritage does not accept 23andMe V2 files, only V3, V4 and V5.

Recommendations

My recommendations are as follows, and why:

Transfer Costs

Autosomal transfers and matching are free at the vendors who accept transfers, but payment for advanced tools is required.

  • Family Tree DNA – $19 one-time unlock fee for advanced tools
  • MyHeritage – $29 one-time fee for advanced tools
  • GedMatch – many tools free, but for Tier 1 advanced tools, $10 per month

All great values!

Please note that as vendors change testing chips and file formats, other vendors who accept transfers will need time to adapt. I know it’s frustrating sometimes, but it’s a sign that technology is moving forward. The good news is that after the wait, if there is one, you’ll have a brand new group of genealogy matches – many holding clues for you to decipher.

I’m in all of the databases, so see you there.

Full or Half Siblings?

Many people are receiving unexpected sibling matches. Everyday on social media, “surprises” are being reported so often that they are no longer surprising – unless of course you’re the people directly involved and then it’s very personal, life-altering and you’re in shock. Staring at a computer screen in stunned disbelief.

Conversely, sometimes that surprise involves people we already know, love and believe to be full siblings – but autosomal DNA testing casts doubt.

If your sibling doesn’t match at all, download your DNA files and upload to another company to verify. This step can be done quickly.

Often people will retest, from scratch, with another company just for the peace of mind of confirming that a sample didn’t get swapped. If a sample was swapped, then another unknown person will match you at the sibling level, because they would be the one with your sibling’s kit. It’s extremely rare, but it has happened.

If the two siblings aren’t biologically related at all, we need to consider that one or both might have been adopted, but if the siblings do match but are predicted as half siblings, the cold fingers of panic wrap themselves around your heart because the ramifications are immediately obvious.

Your full sibling might not be your full sibling. But how can you tell? For sure? Especially when minutes seem like an eternity and your thoughts are riveted on finding the answer.

This article focuses on two tools to resolve the question of half versus full siblingship, plus a third safeguard.

Half Siblings Versus Step-Siblings

For purposes of clarification, a half sibling is a sibling you share only one parent with, while a step-sibling is your step-parent’s child from a relationship with someone other than your parent. Your step-parent marries your parent but is not your parent. You are not genetically related to your step-siblings unless your parent is related to your step-parent.

Parental Testing

Ideally two people who would like to know if they are full or half siblings would have both parents, or both “assumed” parents to compare their results with. However, life is seldom ideal and parents aren’t always available. Not to mention that parents in a situation where there was some doubt might be reluctant to test.

Furthermore, you may elect NOT to have your parents test if your test with your sibling casts doubt on the biological connections within your family. Think long and hard before exposing family secrets that may devastate people and potentially destroy existing relationships. However, this article is about the science of confirming full versus half siblings, not the ethics of what to do with that information. Let your conscience be your guide, because there is no “undo” button.

Ranges Aren’t Perfect

The good news is that autosomal DNA testing gives us the ability to tell full from half-siblings by comparing the siblings to each other, without any parent’s involvement.

Before we have this discussion, let me be very clear that we are NOT talking about using these tools to attempt to discern a relationship between two more distant unknown people. This is only for people who know, or think they know or suspect themselves to be either full or half siblings.

Why?

Because the ranges of the amount of DNA found in people sharing close family relationships varies and can overlap. In other words, different degrees of relationships can be expected to share the same amounts of DNA. Furthermore, except for parents with whom you share exactly 50% of your autosomal DNA (except males don’t share their father’s X chromosome), there is no hard and fast amount of DNA that you share with any relative. It varies and sometimes rather dramatically.

The first few lines of this Relationship Chart, from the 2016 article Concepts – Relationship Predictions, shows both first and second degree relationships (far right column).

Sibling shared cM chart 2016.png

You can see that first degree relations can be parent/child, or full siblings. Second degree relationships can be half siblings, grandparents, aunt/uncle or niece/nephew.

Today’s article is not about how to discern an unknown relation with someone, but how to determine ONLY if two people are half or full siblings to each other. In other words, we’re only trying to discern between rows two and three, above.

As more data was submitted to Blaine Bettinger’s Shared cM Project, the ranges changed as we continued to learn. Blaine’s 2017 results were combined into a useful visual tool at DNAPainter, showing various relationships.

Sibling shared cM DNAPainter.png

Note that in the 2017 version of the Shared cM Project, the high end of the half sibling range of 2312 overlaps with the low end of the full sibling range of 2209 – and that’s before we consider that the people involved might actually be statistical outliers. Outliers, by their very definition are rare, but they do occur. I have seen them, but not often. Blaine wrote about outliers here and here.

Full or Half Siblings?

So, how to we tell the difference, genetically, between full and half siblings?

There are two parts to this equation, plus an optional third safeguard:

  1. Total number of shared cM (centiMorgans)
  2. Fully Identical Regions (FIR) versus Half Identical Regions (HIR)

You can generally get a good idea just from the first part of the equation, but if there is any question, I prefer to download the results to GedMatch so I can confirm using the second part of the equation too.

The answer to this question is NOT something you want to be wrong about.

Total Number of Shared cM

Each child inherits half of each parent’s DNA, but not the same half. Therefore, full siblings will share approximately 50% of the same DNA, and half siblings will share approximately 25% when compared to each other.

You can see the differences on these charts where percentages are converted into cM (centiMorgans) and on the 2017 combined chart here.

I’ve summarized full and half siblings’ shared cMs of DNA from the 2017 chart, below.

Relationship Average Shared cM Range of Shared cM
Half Siblings 1,783 1,317 – 2,312
Full Siblings 2,629 2,209 – 3,394

Fully Identical and Half Identical Regions

Part of the DNA that full siblings inherit will be the exact same DNA from Mom and Dad, meaning that the siblings will match at the same location on their DNA on both Mom’s strand of DNA and Dad’s strand of DNA. These sections are called Fully Identical Regions, or FIR.

Half siblings won’t fully match, except for very small slivers where the nucleotides just happen to be the same (identical by chance) and that will only be for very short segments.

Half siblings will match each other, but only one parent’s side, called Half Identical Regions or HIR.

Roughly, we expect to see about 25% of the DNA of full siblings be fully identical, which means roughly half of their shared DNA is inherited identically from both parents.

Understanding the Concept of Half Identical Versus Fully Identical

To help understand this concept, every person has two strands of DNA, one from each parent. Think of two sides of a street but with the same addresses on both sides. A segment can “live” from 100-150 Main Street, er, I mean chromosome 1 – but you can’t tell just from the address if it’s on Mom’s side of the street or Dad’s.

However, when you match other people, you’ll be able to differentiate which side is which based on family members from that line and who you match in common with your sibling. This an example of why it’s so important to have close family members test.

Any one segment on either strand being compared between between full siblings can:

  • Not match at all, meaning the siblings inherited different DNA from both parents at this location
  • Match on one strand but not the other, meaning the siblings inherited the same DNA from one parent, but different DNA from the other. (Half identical.)
  • Match identically on both, meaning the siblings inherited exactly the same DNA in that location from both parents. (Fully identical.)

I created this chart to show this concept visually, reflecting the random “heads and tails” combination of DNA segments by comparing 4 sets of full siblings with one another.

Sibling full vs half 8 siblings arrows

This chart illustrates the concept of matching where siblings share:

  • No DNA on this segment (red arrow for child 1 and 2, for example)
  • Half identical regions (HIR) where siblings share the DNA from one parent OR the other (green arrow for child 1 and 2, for example, where the siblings share brown from mother)
  • Fully identical regions (FIR) where they share the same segment from BOTH parents so their DNA matches exactly on both strands (black boxed regions)

If a region isn’t either half or fully identical, it means the siblings don’t match on that piece of DNA at all. That’s to be expected in roughly 50% of the time for full siblings, and 75% of the time for half siblings. That’s no problem, unless the siblings don’t match at all, and that’s entirely different, of course.

Let’s look at how the various vendors address half versus full siblings and what tools we have to determine which is which.

Ancestry

Ancestry predicts a relationship range and provides the amount of shared DNA, but offers no tools for customers to differentiate between half versus full siblings. Ancestry has no chromosome browser to facilitate viewing DNA matches but shared matches can sometimes be useful, especially if other close family members have tested.

Sibling Ancestry.png

Update 4-4-2019 – I was contacted by a colleague who works for an Ancestry company, who provided this information: Ancestry is using “Close Family” to designate avuncular, grandparent/grandchild and half-sibling relationships. If you see “Immediate Family “the relationship is a full sibling.

Customers are not able to view the results for ourselves, but according to my colleague, Ancestry is using FIRs and HIRs behind the scenes to make this designation. The Ancestry Matching White Paper is here, dating from 2016.

If Ancestry changes their current labeling in the future, this may not longer be exactly accurate. Hopefully new labeling would provide more clarity. The good news is that you can verify for yourself at GedMatch.

A big thank you to my colleague!

MyHeritage

MyHeritage provides estimated relationships, a chromosome browser and the amount of shared DNA along with triangulation but no specific tool to determine whether another tester is a full or half sibling. One clue can be if one of the siblings has a proven second cousin or closer match that is absent for the other sibling, meaning the siblings and the second cousin (or closer) do not all match with each other.

Sibling MyHeritage.png

Family Tree DNA

At Family Tree DNA, you can see the amount of shared DNA. They also they predict a relationship range, include a chromosome browser, in common matching and family phasing, also called bucketing which sorts your matches into maternal and paternal sides. They offer additional Y DNA testing which can be extremely useful for males.

Sibling FamilyTreeDNA.png

If the two siblings in question are male, a Y DNA test will shed light on the question of whether or not they share the same father (unless the two fathers are half brothers or otherwise closely related on the direct paternal line).

Sibling advanced matches.png

FamilyTreeDNA provides Advanced Matching tools that facilitate combined matching between Y and autosomal DNA.

Sibling bucketing both.png

FamilyTreeDNA’s Family Finder maternal/paternal bucketing tool is helpful because full siblings should be assigned to “both” parents, shown in purple, not just one parent, assuming any third cousins or closer have tested on both sides, or at least on the side in question.

As you can see, on the test above, the tester matches her sister at a level that could be either a high half sibling match, or a low full sibling match. In this case, it’s a full sibling, not only because both parents tested and she matched, but because even before her parents tested, she was already bucketed to both sides based on cousins who had tested on both the maternal and paternal sides of the family.

GedMatch

GedMatch, an upload site, shows the amount of shared DNA as well. Select the One-to-One matching and the “Graph and Position” option, letting the rest of the settings default.

Sibling GedMatch menu.png

GedMatch doesn’t provide predicted relationship ranges as such, but instead estimates the number of generations to the most recent common ancestor – in this case, the parents.

Sibling GedMatch total.png

However, GedMatch does offer an important feature through their chromosome browser that shows fully identical regions.

To illustrate, first, I’m showing two kits below that are known to be full siblings.

The green areas are FIR or Fully Identical Regions which are easy to spot because of the bright green coloring. Yellow indicate half identical matching regions and red means there is no match.

Sibling GedMatch legend.png

Please note that this legend varies slightly between the legacy GedMatch and GedMatch Genesis, but yellow, green, purple and red thankfully remain the same. The blue base indicates an entire region that matches, while the grey indicates an entire region not considered a match..

Sibling GedMatch FIR.png

Fully identical green regions (FIR) above are easy to differentiate when compared with half siblings who share only half identical regions (HIR).

The second example, below, shows two half-siblings that share one parent.

Sibling GedMatch HIR.png

As you can see, there are slivers of green where the nucleotides that both parents contributed to the respective children just happen to be the same for a very short distance on each chromosome. Compared to the full sibling chart, the green looks very different.

The half-sibling small green segments are fully identical by chance or by population, but not identical by descent which would mean the segments are identical because the individuals share both parents. These two people don’t share both parents.

The fully identical regions for full siblings are much more pronounced, in addition to full siblings generally sharing more total DNA.

GedMatch is the easiest and most useful site to work with for determining half versus full siblings by comparing HIR/FIR. I wrote instructions for downloading your DNA from each of the testing vendors at the links below:

Twins

Fraternal twins are the same as regular siblings. They share the same space for 9 months but are genetically siblings. Identical twins, on the other hand, are nearly impossible to tell apart genetically, and for all intents and purposes cannot be distinguished in this type of testing.

Sibling GedMatch identical twin.png

Here’s the same chart for identical twins.

23andMe

23andMe also provides relationship estimates, along with the amount of shared DNA, a chromosome browser that includes triangulation (although they don’t call it that) and a tool to identify full versus half identical regions. 23andMe does not support trees, a critical tool for genealogists.

Unfortunately, 23andMe has become the “last” company that people use for genealogy. Most of their testers seem to be seeking health information today.

If you just happen to have already tested at 23andMe with your siblings, great, because you can use these tools. If you have not tested at 23andMe, simply upload your results from any vendor to GedMatch.

At 23andMe, under the Ancestry, then DNA Relatives tabs, click on your sibling’s match to view genetic information, assuming you both have opted into matching. If you don’t match your sibling, PLEASE be sure you BOTH have completely opted in for matching. I can’t tell you how many panic stricken siblings I’ve coached who weren’t both opted in to matching. If you’re experiencing difficulty, don’t panic. Simply download both people’s files to GedMatch for an easier comparison. You can find 23andMe download instructions here.

Sibling 23andMe HIR.png

Scrolling down, you can see the options for both half and completely identical segments on your chromosomes as compared to your match. Above,  my child matches me completely on half identical regions. This makes perfect sense, of course, because my father and my child’s father are not the same person and are not related.

Conversely, this next match is my identical twin whom I match completely identically on all segments.

Sibling 23andMe FIR.png

Confession – I don’t have an identical twin. This is actually my V3 test compared with my V4 test, but these two tests are in essence identical twin tests.

Unusual Circumstances

The combination of these two tools, DNA matching and half versus fully identical regions generally provides a relatively conclusive answer as to whether two individuals are half or full siblings. Note the words generally and relatively.

There are circumstances that aren’t as clear cut, such as when the father of the second child is a brother or other close relative of the first child’s father – assuming that both children share the same mother. These people are sometimes called three quarters siblings or niblings.

In other situations, the parents are related, sometimes closely, complicating the genetics.

These cases tend to be quite messy and should be unraveled with the help of a professional. I recommend www.dnaadoption.com (free unknown parent search specialists) or Legacy Tree Genealogists (professional genealogists.)

The Final SafeGuard – Just in Case

A third check, should any doubt remain about full versus half siblings, would be to find a relative that is a second cousin or closer on the presumed mother’s side and one on the presumed father’s side, and compare autosomal results of both relatives to both siblings.

There has never been a documented case of second cousins or closer NOT matching each other. I’m unclear about second cousins once removed, or half second cousins, but about 10% of third cousins don’t match. To date, second cousins (or closer) who didn’t match, didn’t match because they weren’t really biological second cousins.

If the two children are full siblings meaning the biological children of both the presumed parents, both siblings will match the 2nd cousin or closer on the mother’s side AND the 2nd cousin or closer on the father’s side as well. If they are not full siblings, one will match only on the second cousin on the common parent’s side.

You can see in the example below that Child 1 and Child 2, full siblings, match both Hezekiah (green), a second cousin from the father’s side, as well as Susan (pink), a second cousin from the mother’s side.

Sibling both sides matching.png

If one of the two children only matches one cousin, and not the other, then the person who doesn’t match the cousin from the father’s side, for example, is not related to the father – although depending on the distance of the relationship, I would seek an additional cousin to test through a different child – just in case.

You can see in the example below that Child 2 matches both Hezekiah (green) and Susan (pink), but Child 1 only matches Susan (pink), from the mother’s side, meaning that Child 1 does not descend from John, so isn’t the child of the Presumed Father (green).
Sibling both sides not matching.png

If neither child matches Hezekiah, that’s a different story. You need to consider the possibility of one of the following:

  • Neither child is the child of the Presumed Father, and could potentially be fathered by different men
  • A break occurred in the genetic line someplace between John and Hezekiah or between John and the Presumed Father.

In other words, the only way this safeguard works as a final check is if at least ONE of the children matches both presumed parents’ lines with a second cousin or closer.

And yes, these types of “biological lineage disruptions” do occur and much more frequently that first believed.

In the End

You may not need this safeguard check when the first and second methodologies, separately or together, are relatively conclusive. Sometimes these decisions about half versus full siblings incorporate non-genetic situational information, but be careful about tainting your scientific information with confirmation bias – meaning unintentionally skewing the information to produce the result that you might desperately want.

When I’m working with a question as emotionally loaded as trying to determine whether people are half or full siblings, I want every extra check and safeguard available – and you will too. I utilize every tool at my disposal so that I don’t inadvertently draw the wrong conclusion.

I want to make sure I’ve looked under every possible rock for evidence. I try to disprove as much as I try to prove. The question of full versus half siblingship is one of the most common topics of the Quick Consults that I offer. Even when people think they know the answer, it’s not uncommon to ask an expert to take a look to confirm. It’s a very emotional topic and sometimes we are just too close to the subject to be rational and objective.

Regardless of the genetic outcome, I hope that you’ll remember that your siblings are your siblings, your parents are your parents (genetic or otherwise) and love is love – regardless of biology. Please don’t lose the compassionate, human aspect of genealogy in the fervor of the hunt.

Ancestry’s ThruLines Dissected: How to Use and Not Get Bit by the ‘Gators

Ancestry’s new tool, ThruLines has some good features and a lot of potential, but right now, there are a crop of ‘gators in the swimmin’ hole – just waiting for the unwary. Here’s help to safely navigate the waters and not get bit!

Gator

Let’s start with first things first.

Maybe it’s wishful thinking or a slip of the keyboard (or phone) but I see people referring to ThruLines as TrueLines, and that’s absolutely NOT true. ThruLines must be verified and proven, just like connections with trees must always be proven – especially when new ancestors are suggested.

ThruLines are not necessarily true lines.

Having said that, there’s lots to unpack here, so let’s get started looking at Ancestry’s latest discovery tool, ThruLines.

It took me a few days to wrap my head around this – meaning what ThruLines is attempting to do, with what information, and why. In other words:

  • How is ThruLines supposed to help us?
  • How can ThruLines actually help us?
  • What are the limitations and dangers?
  • How can we avoid the problems?

The difference in the answer depends on your goals. Let’s dissect ThruLines into pieces to see how it can help with genealogy, when and where – along with what to avoid. There are some useful features here alongside some very large neon-flashing danger signs right beside the ‘gator pond.

What is ThruLines?

Ancestry’s blog announcing ThruLines can be seen here.

ThruLines does two things:

  • ThruLines groups DNA matching descendants by ancestor. ThruLines shows you, by ancestor, which people match your DNA and claim to be descended from that same ancestor. Notice the words “claim to be.” As always, when other people’s trees are involved, there is a danger of conflated trees and other concerns. We’ll discuss that shortly.

Especially for more closely related relatives, this grouping of DNA matches by ancestor is a great feature because their trees and who they believe they are descended from are more likely to be accurate in the past 3 or 4 generations when the relationship with the ancestor is a result of direct knowledge as opposed to further back where the relationship to an ancestor is a result of genealogical research. This also means the relationship to your match is easier for you to confirm, if you don’t already have your match in your tree. These gathered matches allow you to add family members and cousins to your tree. You never know who might have photos or other information, so matching and discovering that you are connected makes it easy to reach out.

These match groupings use ancestors that you already have in your tree.

  • ThruLines provides “suggestions” for potential ancestors by extrapolating from other trees. These “suggestions” include replacing your researched ancestors with other ancestors from other people’s (often inaccurate) trees, many of whom are not DNA matches to you. This is Gatorland!

Ancestry has provided this product announcement but has not yet released a white paper about how ThruLines performs the following:

  • Utilizes DNA matches.
  • Utilizes trees, including how decisions are made about which trees to use and how to suggest potential ancestors.
  • How Ancestry determines when to ignore your existing ancestor in your tree in favor of a suggested replacement.
  • The weighting between DNA and tree evidence. In some cases, nonsensical ancestors are being suggested through people’s step-parent’s lines, or ancestors’ “other spouses” lines that the tester is not biologically connected to, so the Ancestry selection process cannot be solely based on DNA matching and in some cases, is clearly not based on DNA matching at all.

Hopefully, a white paper will be coming shortly.

Caveats

If you’re an experienced genealogist, I’m not worried about you. You already understand about ‘gators, meaning the caveats and concerns about the massive number of incorrect trees.

My primary concern is that ThruLines encourages people to believe that ancestors are being suggested because DNA has confirmed that a specific ancestor is theirs. In many cases, erroneous trees have propagated for years, and now all of those people are “wrong together” so their incorrect ancestor is being suggested as an ancestor for many more people. Worse yet, multiple wrong trees are being stitched together by Ancestry in ThruLines.

I wish Ancestry provided a visible warning someplace where users CAN’T MISS IT. MyHeritage does exactly that, even in the name of their similar feature, Theory of Family Relativity.

Buried in the Ancestry support document for ThruLines, I found this:

ThruLines accuracy

This should be a required clickthrough before anyone can use ThruLines.

Accessing ThruLines

Not everyone at Ancestry has ThruLines yet. Ancestry has been struggling the past few days and ThruLines have been coming and going. ThruLines is in beta and will be rolled out during the month of March.

For ThruLines to work, you must be sure:

  • Your tree is connected to your DNA.
  • Your tree is either public or a private searchable tree. Unsearchable trees won’t have ThruLines.
  • Your tree is at least 3 or 4 generations deep.
  • You only have one kit for any individual person connected to that person in the same tree. If you have multiple kits for the same person connected to one tree, only one kit will have ThruLines. If this is your situation, you can create a “twin” to yourself in your tree and attach the second kit to that person and both kits should get ThruLines. There aren’t many people like me who have tested twice with AncestryDNA, so this shouldn’t be a problem for most people.

You can have multiple kits attached to the same tree, but each kit must be connected to a different person in the tree

If you want to know if ThruLines is available on your account or you are having problems with ThruLines, I wrote about that in the article, “Ancestry’s Disappearing ThruLines – Now You See Them, Now You Don’t.”

Myths and Misconceptions

  • ThruLines is NOT telling you or confirming that a specific ancestor IS your ancestor.
  • ThruLines is NOT modifying or automatically doing anything to your tree. The ThruLines “trees” you are seeing are constructed for ThruLines.
  • You are NOT necessarily related to, nor have DNA matches with the people whose trees are used to suggest potential ancestors.

Warning

For individuals seeking unknown parents, if you see your name beneath a placard that shows a “private” individual in a hashed box above your name, this does NOT mean your parent has been discovered. This only means that Ancestry has “paired” you with a potential ancestor that happens, in your case, to be a parent based on some combination of name similarity (yours) and a person with a similar surname in someone else’s tree.

If you have a parent/child match, it will be the first match on your match list. Look there.

It’s heartbreaking to get excited only to learn that the ThruLines “potential parent” shown for you has nothing to do with genetics – so be prepared for this possibility and don’t get excited. Check your DNA match list.

Facts

  • According to Crista Cowan in her RootsTech video, ThruLines is a replacement for Circles. After working with both my ThruLines and Circles, it became obvious very quickly that Circles have not been updated for some time, probably months. If you have Circles or New Ancestor Discoveries (which have been dormant for the past couple years), please archive them so you don’t lose any information you might have. I wrote about how to do that here.
  • New Ancestor Discoveries were discontinued roughly two years ago, so you may not have any.
  • Shared Ancestor Hints (green leaves) is no longer working. Neither is Filter By Common ancestors. I sure hope they fix both of these (probably related) bugs.
  • Any ThruLine card in a dotted edge box is a POTENTIAL ANCESTOR and is very likely incorrect.ThruLines hashed line.png
  • Any ThruLine card in a solid line box when you mouse over the card is an ancestor currently found in your tree. It’s as correct as your tree.ThruLines solid line.png
  • Just because you have an ancestor in your tree does NOT mean that Ancestry will use that ancestor. Ancestry may provide another potential ancestor from someone else’s tree. Watch for the hashed lines and be cognizant of who is already in your tree, and why!
  • On the ThruLine trees, any person, meaning ancestor OR other person in a grey hashed line box is only a suggestion based on someone else’s tree or multiple trees.
  • ThruLines shows you which tree that ancestor was “suggested” from, allowing you to click through to that tree and view their documentation.
  • On the ThruLine trees, any person in a solid edge box is from your own tree, shown with red arrows below, while any suggested individual is shown with hashed edges, shown with green arrows.

  • The summary below the ancestor’s name may indicate that you’re related to XYZ ancestor in <some number> of ways, but review the people you match very closely because you may be related to them, but not through the ancestor or in the way shown.

ThruLines number of matches.png

  • If there was a second marriage, ThruLines may be attributing your relationship to the un-related spouse. The descendants shown may be from the “other” marriage and that person’s ancestors. If you’re thinking the unrelated spouse’s ancestors can’t be genetic, you’re right – at least not through that line. Be very careful. You’re in ‘gator territory.
  • Furthermore, Ancestry may be suggesting ancestors of the “step-spouse” or other tangential line as well. More ‘gators.
  • Just because you match 5 descendants of XYZ ancestor, that does not mean any of these people match each other. In fact, you may match some of these people through another line entirely.
  • You can still click through to view the DNA comparison feature at Ancestry. However, since the Shared Ancestor Hints (green leaves) is not working at all, you will not be able to see the side-by-side tree comparison feature☹

ThruLines common ancestors.png

  • Using Shared Matches on the comparison page, you may be able to determine if some of these individuals do in fact match each other which helps to increase the likelihood of common ancestry in a specific line.

ThruLines shared matches 1.png

  • ThruLines does not replace Shared Ancestor Hints (green leaves) although ThruLines organizes the Shared Ancestor Hints by ancestor. Currently Shared Ancestor Hints is not working and says you have no matches with shared ancestors which is clearly incorrect if you previously had any Shared Ancestor Hints.
  • ThruLines may “add” projected ancestors to matches whose trees don’t reach far enough back in time, but who connect with another tree who connects with your tree. This occurs in ThruLines, not in your own tree unless you specifically add the information there. This additive “tree extension” effort is very similar to the WeRelate application which was infamously wrong – more like WeDontRelate.
  • You will still receive potential parent hints for ancestors on your actual tree, some of which will (or may) also be reflected in ThruLines. In some cases, the hint on your tree and the ThruLine suggested “potential ancestor” are different, so check both places.

Thrulines potential parent tree.png

  • ThruLines only reaches back 7 generations, so if you’re looking for a breakthrough or descendants from ancestors before that time, you won’t see them in ThruLines. Previously in this regard in relationship to Circles, Ancestry had said that there were too many unknown family lines and multiple relationship paths that far back in time.
  • Many of the ancestor ThruLines share exactly the same descendants. For example, my Dutch line only has a limited number of testers, so the same 10 people are listed for generation after generation going up in the pedigree (back in time.)
  • Once ThruLines offers a potential ancestor, they continue offering parents and grandparents of that potential ancestor until they run out of ancestors, reach the 8th generation or some other criteria for stopping. If this is a legitimate line, great – and if not, it’s a royal pain without an “off” button to reject known erroneous “potential ancestors.” “Gators having baby ‘gators!
  • There is no way to “ignore,” “reject” or tell Ancestry to “disconnect” or remove a potential ancestor. I hope they will add this feature soon. This could be useful if they suggest another ancestor, especially in lines where you are truly at a brick wall. New “potential ancestors” would provide you with ideas for who/where to search.
  • There is also no way to mark a ThruLines card as “seen” so you don’t review it again.
  • Having two kits connected to the same person in your tree will (at the time of this writing) prevent one of those kits from receiving ThruLines. In my case, I took a V1 and a V2 test and had them both connected to my own record. This can be solved by adding yourself as a sibling and connecting one kit to the sibling.
  • ThruLines is free for everyone for now but may require a subscription in the future. (Don’t forget about the Insight subscription to access DNA features only, assuming it still exists, but you must call support to obtain that limited subscription.)

Suspicions

  • That trees with “more” sources are weighted more heavily than trees without “more” sources. Case in point is my own tree for an ancestor who little is known about, so I only had an estimated birth and death year. However, Ancestry suggested a replacement with a very robust but nonsensical tree that incorporates “lots” of documentation. In fact, this amazing woman has birth records from Washington DC 1830-1955 (which didn’t exist in the 1700s when this woman lived), New Hampshire 1714-1904, PA 1669-2013 and who died in TN but is buried in PA. Any modicum of logic would have immediately down-weighted this tree’s veracity.
  • That not all relationships are genetically based. For example, I have 15 ancestors for whom I’m the only DNA tester listed, legitimately, so why are those ancestors shown as a ThruLine for me? No DNA is involved.
  • That Ancestry created, updated or still has a version of that “One World Tree” someplace, because some of this information is drawn from old trees with information removed long (as in years) ago. Does Ancestry know where this information was obtained from customer trees, and how they selected the specific tree to use? Do they update it? How often and what logic decides what is incorporated into that tree? I notice that in some cases, suggested ancestors’ spouses came from different users’ trees, even when the same spouse was in the same tree.
  • That projected ancestors are entirely tree based only, not genetically based.
  • Although Ancestry has not yet told us how they weight tree matches, it stands to reason that the most complete records are the most likely to be matched successfully – so be sure your ancestor’s records are as complete as possible.
  • Having said that, some of the suggested potential ancestors replacing my existing ancestors have much LESS documentation than my own tree, including some with the only “source” being Ancestry trees. I have no idea what Ancestry is actually doing, when, or why.

Accessing ThruLines

Sign on to your account and click on DNA and then “Your DNA Results Summary.”

Click on “Extras” and then “Ancestry Lab.”

ThruLines Ancestrylab

Once there, enable the beta functions. I’m not positive you need to do this for ThruLines, but there have been so many issues that I’d recommend doing this, just in case.

ThruLines Ancestrylab enable

If you have ThruLines available on your account, you’ll see this on your DNA Summary page.

ThruLines explore.png

Click on the green box to access ThruLines.

Please note that as of this writing, ThruLines is not stable, meaning that ThruLines and ancestors, as well as matches are tending to come and go. Some features are working sporadically and some not at all. The Shared Ancestor Hints and Common Ancestors filter is not working at all, even when ThruLines is functioning.

Sorting ThruLines

After working with ThruLines, I discovered, for me, working the different types of records together was easiest, because what I do with those records differs.

Records fall into the following categories:

  • Existing ancestors in your tree
  • Potential (suggested) ancestors

In fact, Ancestry provides the ability to filter in exactly that fashion, at the top of the ThruLines page on the left side.

ThruLines filter.png

Let’s look at these two types of records individually, because I use them differently.

In case you’re wondering how I track my ThruLines, I created a spreadsheet that includes columns for:

  • Number – numbered so that I know I’ve accounted for all 254 ancestors through 7 generations
  • Generation in which that ancestor is found – for example my 4 grandparents are generation 2
  • Surname of Ancestor
  • First name of Ancestor with birth year if multiple people by that same surname
  • “Should Be” column for when Ancestry suggests a replacement ancestor for a correct Ancestor I have in my tree. “Should be” is the correct ancestor’s name.
  • Existing – meaning does the ancestor exist in my tree already and is the ThruLines card provided by Ancestry for this existing ancestor from my tree
  • Potential – meaning is this a “potential ancestor” as indicated by a hashed line. Believe it or not, I have several cases where I have an ancestor by a specific name in my tree and Ancestry has suggested a different ancestor by the same name that is a conflated version of my ancestor and another person by that same name, so the answer can be yes for both “existing” and “potential.”
  • Members – how many people match in this ancestor’s group. The number of matching people is easy to see at the top of the ThruLine card when you click on the Ancestor card to open.

ThruLines may be related.png

  • Comments – anything that comes to mind such as why the suggested ancestor is wrong, something to look at, if they are a Y or mtDNA candidate, etc.

ThruLines spreadshet.png

Here’s an example of my spreadsheet.

I also color coded the ThruLines ancestors according to the groups identified later in this article so that I could filter by color. In the example above, the grey entry is an example of a correctly gathered ancestor and the red entry is a hypothetical example of an incorrect entry. If an incorrect person was listed, I would enter the correct ancestor in the “should be” column.

I had to create this spreadsheet to wrap my head around what Ancestry was doing with ThruLines, and to some extent, perhaps determine why.

I would suggest that you read through this entire article before deciding how to handle your ThruLines, then come back and create this spreadsheet if you want to. I had to create a spreadsheet to wrap my head around what was going on with ThruLines so I could write this article.

Existing Ancestors

ThruLines only “sees” ancestors on your linked tree. That means the tree linked to your DNA results.

If you switch trees, you’ll have to give Ancestry some amount of time to switch your results to the new tree. No, I don’t know how long that is in actuality. Hours to days. Ancestry suggests two days. Many people are reporting much longer waits.

What you’ll see when the process is complete is a very nicely organized set of “ancestor cards” that begins with the closest ancestors you have in your linked tree.

ThruLines cards.png

Linking Your Tree

If your tree is not linked, PLEASE LINK IT. You will not have ThruLines if your tree is not linked correctly.

To link your tree, click on “DNA” at the top of the page, and then on DNA Summary.

ThruLines settings.png

Click on the Settings gear in the upper right corner of the page.

Be sure you are participating in matching and then link your tree in this section:

ThruLines link tree.png

Exploring ThruLines

I have 161 individual ancestors listed on cards at Ancestry, along with 49 potential ancestors, although this number varies from hour to hour and day to day.

Existing ancestors in your tree have a solid line around their card when your cursor is above the ancestor.

ThruLines existing ancestor.png

Potential ancestors have a hashed line around their card.

ThruLines potential ancestor.png

This might be a good time to mention that Ancestry includes information from searchable but private trees. This means that information from many of those private trees that so frustrate genealogists is included. It may also mean that trees people are using as “quick and dirty trees” and they forgot to make unsearchable are included too.

However, if you have a private searchable tree, this now means that you too will have ThruLines.

As frustrating as these “private” cards appear at first glance, they actually aren’t useless. I clicked on this private placard and look what I see.

ThruLines private.png

This potential ancestor happens to be inaccurate, but at least I can see something.

ThruLines contact.png

Sometimes you’ll see this instead (even if the person lived so long ago that they can’t possibly be living), or if you’re lucky, the following which at least provides the name of the suggested ancestor so you can search elsewhere.

ThruLines private ancestor identified.png

I’m very grateful for this change to provide the ability to at least identify the ancestor being referenced.

Looking at my Ancestry tree, to the 8th generation (meaning 7 generations, inclusive, counting from my mother, means that if you expand your tree once, every ancestor other than the last column should be shown on a ThruLines card as illustrated below.

ThruLines 7 generations.png

In 7 generations, there are a total of 254 ancestors, counting our parents as generation 1.

Let’s break my 254 ancestors down into categories based on the Ancestry ThruLines.

Group 1 – Ancestors with No DNA Matches

Based on the fact that I’m the only child that has tested as a descendant of my mother, and she has a card, Ancestry appears to have taken every one of those 254 individuals and processed them in some fashion. I say this because I have a total of 20 ancestors in my tree with whom there are no DNA matches attributable to that ancestor.

ThruLines no matches.png

In fact, it’s this line of relatively recent German immigrants, the parents having arrived in the mid-1850s. Jacob Kirsch and Barbara Drechsel (Drexler) didn’t have a lot of children and many of those children didn’t marry and have children, which leaves a small descendant pool to test.

Clearly, based on this, the ThruLines, meaning the cards shown, aren’t generated based on a DNA match. That’s fine, except that I understood that a ThruLines card meant that you HAD a DNA match first, then secondarily a matching tree as well.

Obviously, that’s a misconception.

I’ll be keeping a running scorecard of my 254 ancestors and how they break down in ThruLines.

Ancestors Number Comments

Remainder 234

Group 2 – Missing Ancestors Altogether

This next group is probably the easiest to account for, because they are missing in the Ancestry ThruLines cards altogether. They are clearly in my tree, but they have no ThruLines card showing that they exist. If they were only in the 7th generation, I could understand that they are missing AND don’t have hints about ancestors in earlier generations – because Ancestry (unfortunately) doesn’t provide anything in the 8th generation, but that’s not the case here. Two full generations are missing entirely.

ThruLines missing branch.png

This entire branch of my mother’s tree is missing altogether – both parents and all 4 grandparentts of Angenietje Houtsma.

It’s clearly NOT because there aren’t any DNA matches, because the Kirsch branch in the last example has no matches and still has ThruLines cards for ancestors.

It’s not because there aren’t parents, because Angenietje Houtsma has grandparents who should have cards as well, AND, those grandparents have record hints. So, it’s not like these people are unknown to the system, because they aren’t. In this one line alone, 6 ancestors are missing.

In the 6th generation, I have a total of 4 missing ancestors who are in my tree but have no cards, and in the 7th generation, 10, for a total of 14 missing ancestors. Where are these ancestors and why don’t they have a ThruLines card?

I have no idea.

Group 3 – Ancestors in My Tree with Gathered Descendants

This next group is the largest group of matches after eliminating the missing ancestors and those with no DNA matches.

This group consists of ancestors who have cards from my tree shown by Ancestry AND with whom I have DNA matches attributed to that line.

Keep in mind that many more people may have DNA tested and are descended from these ancestors, but their DNA doesn’t match my DNA. The only resource available to see that those people match others descended from that ancestor is if you have a Circle for that ancestor, you can check for people NOT shown in this ThruLine grouping.

Ancestry has stated that they are not going to continue to add to the Circles, so if you want that information, archive it now. I wrote about how to do that here.

I will be doing that for every ancestor with a Circle.

Let’s look at Lazarus Estes. He’s my great-grandfather and I know of most of his descendants, or at least I think I do. I have 6 DNA matches that descend from Lazarus.

Thrulines ancestor gathered descendants.png

Ok, maybe I don’t know most of his descendants. I know most of his descendants a generation ago. One of these names I’ve never heard of. The good news is that they might have information that I don’t. Pictures, stories, something.

If your goal is to connect with LIVING people, you’ll love this ThruLines feature.

In recent or relatively close generations, people are likely to know their genealogy which means their parents and grandparents. For example, I don’t question for a minute that the three descendants of Gracie Estes Long know that she’s their grandmother. I would hope that Tyler knows that my half-sister is his great-grandmother, but I suspect he has no idea who I am. His mother and grandfather are still living, which is why they are marked as private and have hashed lines, so he could ask them and I’m sure they know both who Edna was and who I am.

As you move further back in time where people are depending on historical research, that’s when the trees become more problematic, entering ‘gator territory, because they adopt and incorporate other people’s trees, believing them to be accurate.

One point that this graphic illustrates quite well is the difference in inherited DNA in the green boxes. Note that with my three 2C1R (second cousins once removed), I share 170cM, 161 cM and a paltry 25cM of DNA with them. That’s a very large difference. Then note that I share LESS with my half 2nd great-nephew, with whom I’m more closely related than with two of my 2C1R. Roll of the genetic dice.

You might notice that I can’t drop down the middle box because there’s not enough space for all 6 matches to show simultaneously. Sometimes you have to scroll back and forth to see the entire graphic, including all the siblings, so you can click at the top on the “List” link to see the people you match who descend from this ancestor in a list format.

ThruLines list.png

There are three additional pieces of information available from this “List” screen.

If you click on “View Relationship,” it takes you back to the tree where you will see only your relationship with that person.

ThruLines relationship.png

Notice that the solid lines mean these people are in my tree, but there’s another hint too. You can see that Becky’s father was taken from her own tree, but her grandmother, Lucy was taken from someone else’s tree. Is that accurate information? Don’t ever assume that it is. The trees are all hotlinks. Verify, verify, verify!!!

If you click on the person’s initial box or name, you’ll be taken to the DNA comparison screen that we’re all familiar with. Be sure to note how you’re related so you can check easily.

ThruLines match info.png

This confirms that Becky didn’t provide any more information than her parents in her tree.

If you click on the segment information in the middle of the “List” screen, you will see the following:

ThruLines relationship percents.png

Please note that these percentages do not correlate with the DNAPainter tool here which I use extensively. Ancestry does remove segments that they feel are “too matchy.”

ThruLines DNAPainter percents.png

There’s a pretty large difference between 40% and almost 52%. I wonder if Ancestry is a victim of their own incorrect trees where relationships are reported inaccurately. If that’s how they are calculating these statistics, it could well explain the discrepancy.

I would think that genealogists who care enough to make the effort to enter their DNA information into Blaine Bettinger’s Shared cM Project, from which the DNAPainter tool is derived would care enough to make sure the relationships reported are accurate. You can contribute to this crowd-sourced effort here.

I have a total of 148 “Ancestor Gathered Descendant Trees.” I know for a fact that not all of them are accurate for any number of reasons, but what I do know is:

  • That my path to the ancestor is accurate because it’s my tree and I’ve spent 40 years performing original research and documenting those ancestors.
  • That I’m somehow related to these people, assuming that the segment is not identical by chance.
  • The identical by chance scenario can be lessened for each match by looking at the Shared Matches for hints based on other people that also descend from the same ancestor.

ThruLines shared matches.png

Checking my match with cousin Beverly to help eliminate the identical by chance scenario, I discover that I do have shared matches with her, and that two of the closest common matches are people I recognize. Becky from my example above and another cousin I know well – both who descend from the same lines and help confirm the legitimacy of Beverly’s match.

With one exception, all of these 9 ancestors are females with no surnames. In the one case where the ancestor is a male, the potential father is incorrect and no mother is offered.

Group 7 – Inaccurate Potential Ancestors (‘Gator City)

I saved this group for last because it’s just painful. As a genealogist, I have to say that truthfully, the fact that Ancestry has suggested 55 ancestors that I know positively are inaccurate terrifies me for the sheer fact that less experienced genealogists will grab gleefully onto these “new ancestors” and perpetuate the Ancestry-provided incorrect trees like kudzu vines. The perception is that these trees are now “proven” by DNA – a statement I’ve seen repeatedly the past several days.

THESE ANCESTORS AND TREES ARE **NOT** PROVEN BY DNA!!!

These trees are predicated upon other people’s inaccurate trees with suggestions being made to replace your ancestors, currently in your trees, with other ancestors from other people’s trees. There seems to be no consistent logic that applies in ‘Gatorland.

The end result will be that even more people will receive inaccurate “Potential Ancestors” because there are yet more of those incorrect trees skewing the algorithm. I don’t know if the criteria for ancestor suggestion is “most numerous” tree or something else. This scenario is the very definition of a vicious ‘gator circle.

The incredibly frustrating aspect of ThruLines for me is when Ancestry ignores the ancestor in my tree that I’ve spent years (if not decades) researching and documenting, and instead suggests a “Potential Ancestor” that defies logic. LHM!

In some cases, such as with Lydia Brown, wife of William Crumley III, the widely disseminated Elizabeth Johnson is shown as the mother of my ancestor, Phoebe Crumley, instead of Lydia Brown. Not only is Elizabeth Johnson incorrect, it’s been proven incorrect for several years now via mitochondrial DNA, AND, I’ve written and published about this case.

Imagine my frustration, to put it mildly, to discover that Ancestry is now ignoring my carefully proven ancestor and suggesting that I replace her with the unproven, erroneous ‘gator. Not only that, but I fully suspect that my tree is NEVER going to be suggested to others, because it’s a (nearly) lone voice lost in the forest of incorrect ancestors.

Truthfully, this makes my blood boil – 55 separate painful times. Once for each incorrect ‘gator masquerading as an ancestor. Why would Ancestry think that replacing my ancestors in my tree with ones from other people’s trees is even remotely a good idea?

To suggest that I “consider” a different ancestor or information in another tree is vastly different than simply ignoring the ancestor I have in my tree and providing a “Potential Ancestor” replacement, like the one in my tree doesn’t even exist. (Not to mention that this attitude in and of itself is both arrogant and condescending.)

If I should consider a different ancestor, I’d at least like for that ancestor to have lived in remotely the right place and time. People did not have children at age 5 nor after they died (except occasionally for men within 9 months), nor did they have 30 children, nor were they married, having children and living in multiple places at the same time. Well, at least not most ancestors😊

The Quality of a potential tree should be part of the recommendation factor, especially if Ancestry is blithely ignoring my existing ancestor in favor of another potential ancestor from someone else’s tree.

Simply telling you how wrong these suggested Potential Ancestors are would not do the situation justice. I’ve documented the circumstances, briefly, with the hope that you will use my experience trying to sort through this ‘gator swamp as a warning for what to look for and consider in your own ThruLines, and how.

What’s worse, when Ancestry ignores your existing ancestor and suggests others, they don’t stop with that one ancestor, but then continue to suggest and propagate ancestors on up your tree for the erroneously suggested ancestors. These recommendations are not based on DNA or your existing ancestor in your tree but on “those other” trees alone.

Let’s look at an example of what Ancestry “suggested” for my Crumley branch. The red Xs document where Ancestry replaced a known ancestor with suggested incorrect ancestors – including on up the tree. (I should have used little ‘gators instead of Xs.)

Thrulines bad tree.png

Unknown H2a1 is an unknown wife of William Crumley II with the H2a1 mitochondrial haplogroup. Ancestry did not assign a potential ancestor for her, but obviously Ancestry “believes” that she was a Johnson, because her father is suggested as Andrew Johnson. Of course, this means that H2a1’s mother is incorrectly “suggested” as well as Andrew Johnson’s wife.

I know this is wrong, because Elizabeth Johnson was a second wife who married William Crumley in 1817, long after his son, my ancestor, William Crumley III was born in 1785. Therefore, it’s impossible that Elizabeth was William III’s mother. Not only that, she was 12 years YOUNGER than William Crumley III. Twelve years younger than her step-son.

Furthermore, Lydia Brown, the proven mother of Phebe Crumley through William Crumley III in the next generation, was ignored as well, and his wife was also given as Elizabeth Johnson through a different tree. This Elizabeth Johnson’s parents were assigned as different parents than the Elizabeth Johnson who married William Crumley II in 1817. Are you confused yet? Believe me, so was I and obviously, so are other people as well as Ancestry.

The end result of this is that not only were my existing ancestors ignored and replaced, but the erroneous trees that are themselves full of impossibilities for the person they are documenting are then suggested to replace mine. Those trees are then cobbled together by Ancestry in a Frankenstein mosaic of patched together ancestors that are blatantly wrong and very difficult to unravel.

And this in only one branch of my extended tree. This scenario happened on multiple branches. If you’re thinking to yourself, “How bad can this really be?”, here’s the graphic of every branch affected, and how.

That old “picture is worth 1000 words” thing.

If you think I’m overreacting, take a look at these graphics which do NOT include missing ancestors or the two that that might potentially be accurate – only the “Potential Ancestors” provided by Ancestry that I know positively are inaccurate.

If your jaw just dropped looking at those red Xs, let this serve as a warning for your own tree.

Below, brief descriptions of what is wrong, and how. Think of this as the ‘gator trap.

Ancestor Suggestion to Replace Accurate with Inaccurate Ancestor
Joseph Bolton My ancestor ignored and suggested similar Joseph Bolton from tree with significantly less information than mine.
Lydia Brown Proven incorrect ancestor based on widely spread speculative misinformation.
Elisabeth Mehlheimer’s mother I already have her mother, Elisabetha Mehlheimer, in my tree. Why suggest a “private” person instead? (This has since disappeared.)
William Moore Replaced my William with another William Moore proven via Y DNA not to be from the same line. The William they suggest has 30 children from 3 “wives” who are obviously the same woman by different variations of a common surname, with many “children” by the same name. This tree has obviously been constructed by indiscriminately “gathering” from other trees. Yet, that tree, according to Ancestry, trumped my own carefully curated tree.
Lucy, wife of William Moore Suggested wife of yet a different wrong William Moore, above, ignoring Lucy in my tree. Birth shown in Giles County, VA but also with an attached England birth document. Shows marriage to two different William Moores, at the same time, neither one where mine lived.
Daniel Vannoy Suggested his brother, Francis, ignoring Daniel in my tree. The Francis tree has many spurious references to IGI records, Family Data Collection and Ancestry trees, but does NOT include my Elijah as his child, so how Ancestry decided to make this connection is baffling.
Sarah Hickerson Suggested Daniel’s wife from a different tree than above where Elijah is included as a child. Which Vannoy brother fathered Elijah Vannoy was proven through DNA matches to the Hickerson family, not Millicent Henderson, wife of Francis Vannoy.
Jotham Brown Because the right wife, Lydia Brown, was ignored, the wrong line continued to be suggested upwards in the tree instead of Jotham Brown, Lydia’s proven father. This “private” tree is for Zopher Johnson, as shown by his connected children even though “Zopher” himself is private. Another Potential Ancestor shows Zopher as a card a generation earlier, along with wife Elizabeth Williamson Cooper, perpetuating this wrong information up the tree another generation.
Phoebe Cole Because the right wife, Lydia Brown, ignored, the wrong line continued to be suggested upwards in the tree instead of Phebe Cole, the wife of Jotham Brown, Lydia’s proven father in my tree. This “private” ancestor is for Catherine Harrison, wife of Zopher Johnson.
James Mann Substituted James Robert Mann, the wrong person, ignoring the accurate person. This continues upstream for 2 more generations.
Mary Cantrell Substituted Mary Jane Wilson, wife of James Robert Mann. The wrong line continued up the tree for 2 more generations.
Michael McDowell Suggested replacing my Michael with a different, less correct, possibly conflated, Michael McDowell.
Samuel Muncy Suggested Samuel Munsey-Muncy, ignoring my Samuel, from a tree that shows a Civil War service record for a man who died in the early 1800s and would have been about 100 during the Civil War. Miraculous! Lots of Family Data Collection and Ancestry Trees sources.
Andrew McKee Suggested replacing my Andrew with a different, incorrect “private” Andrew McKee. The original tree for Andrew has now been made completely private.
Elizabeth, wife of Andrew McKee Ignored my Elizabeth and suggested replacing with another Elizabeth. The matches look to be correct, so the other tree has the two Elizabeths conflated. The only source for the replacement tree is “Ancestry Family Trees.” Sheesh, Ancestry.
James Moore Ignored my proven ancestor and suggested replacing him with a William Moore proven via Y DNA not to be of the same line. This William in the person’s tree was said to be born in Henrico Co., VA, but has an attached birth record from England. Can’t be both.
Mary Rice Ignored Mary Rice and suggested Margaret Hudspeth, wife of the incorrect William Moore, above. Again, shown to be born in Henrico County, with English birth record attached along with IGI record as only sources.
Charles Hickerson Since Sarah Hickerson was ignored, the incorrect family line was perpetuated up the tree with a wrong ancestor for the second generation instead of Charles Hickerson.
Mary Lytle Since Sarah Hickerson was ignored, the incorrect family line was perpetuated up the tree with a wrong ancestor instead of Mary Lytle.
Sarah Rash Ignored mine and suggested replacing with a Sarah Rash that appears to be more fleshed out, but the dates are all based on records not belonging to the correct Sarah, including a birth in England despite a shown birth date in 1732 in Spotsylvania Co., VA. We have our Sarah’s birth from the family Bible.
William Moore’s wife, Lucy’s father Nancy Moore’s erroneously given mother’s supposed father, Samuel Little Harwell. This erroneous tree now perpetuated to the second generation.
William Moore’s wife, Lucy’s mother Nancy Moore’s erroneously given mother’s supposed mother, Anne Jackson. Woman who died in 1765 has a SSDA claim record and an 1800s immigration record, even though she was supposedly born in Brunswick Co, VA in 1712. Married Samuel Harwell 5 different times – clearly has simply collected and attached data to their tree without evaluation, but Ancestry thought it was “better” than my tree.
Jotham Brown’s father Because Lydia Brown was misidentified, so was Jotham Brown, and now his father as well, perpetuating garbage up the tree for two more generations
Jotham Brown’s mother Because Lydia Brown was misidentified, so was Jotham Brown, and now his mother as well, perpetuating garbage up the tree for two more generations
John Cole Since Phebe Cole was misidentified, so was her father.
Mary Mercy Kent Since Phebe Cole was misidentified, so was her mother
Michael McDowell Sr. Since the wrong Michael was identified earlier, a wrong father, John McDowell, was also identified, proven by Y DNA not to be related. The son of this John McDowell is yet a different John McDowell than the one Ancestry substituted for my John McDowell.
Wife of Michael McDowell Sr. We don’t know who she was, but we know she wasn’t Magdalena Woods, married to John McDowell. The Magdalena Woods tree they recommended includes 13 Ancestry Family Tree, Family Data Collection and IGI records as sources, plus a German birth record for a person born (supposedly) in 1705 in Ireland, according to the tree itself. Pretty tricky!
Isabel, wife of Michael McDowell Jr. Suggested private father, Ebenezer Hall, and erroneous mother, Dorcas Abbott who lived her entire life in New Hampshire, not Virginia.
James Claxton’s parents Suggested erroneous private father and mother, widely distributed but proven via Y DNA testing not to be of the same line. Ironically, there are other trees for this person that are not private. How and why Ancestry selected the private one is a mystery. Ancestry also suggested his mother, from another tree as Catherine Kathryn Caty Middleton which is incorrect as well.
Joel Cook Ignored Joel, proven ancestor via military records to suggest Henry Cook. Henry’s only daughter, Sarah, in the suggested tree would have been 5 years old when she married and 6 when her first child was born. Another miracle!
Alice, wife of Joel Cook Ignored Alice to suggest wife of Henry Cook from a different tree with the only source being Ancestry Family Trees.
Samuel Muncy Ignored Samuel to suggest Obediah Muncy.
Agnes Craven Ignored, Agnes, wife of Samuel Muncy to suggest “private” person who was the wife of Obediah listed as “Mrs. Obediah.”
Andrew McKee Ignored Andrew McKee who is proven to suggest Hugh McKee who did not live in the correct state to have his child. The next generation up the tree is also incorrect, suggesting a George McKee who had Elizabeth Barnes, mother of Ann McKee, according to Ancestry. Ann McKee’s mother was actually Martha (probably) McCamm. Another potential ancestor card suggests George McKee’s wife is Anna Elizabeth Carney with no sources at all.
Martha possibly McCamm Ignored Martha and suggested wife of Hugh McKee, Mary Nesbit, perpetuating erroneous information for another generation up the tree. Some very convoluted trees in this mess with only source being “Ancestry trees.” This has now been made entirely private.
Elizabeth, wife of Steven Ulrich. Ignored my Elizabeth and suggested Elizabeth Cripe, a surname/person that has been disproven but rampant in trees.
Marie LePrince Ignored proven genealogy that Marie LePrince is the mother of Marguerite de Forest and replaced with Marie Claire Rivet. Shown marrying both in France and in Nova Scotia.
Hannah Drew Ignored my Hannah Drew and replaced with wrong Hannah Drew from another tree with less information, showing only an Ancestry Family Tree and a record showing the birth of her son in England, while the rest of the tree shows his birth in the colonies.
Samuel Mitchell Ignored my Samuel Mitchell and replaced with an erroneous Samuel Mitchell who was supposed to have died in 1756 in Maine, but has a Michigan death record from after 1867. I had no idea people lived to be almost 200 years old. Wow!
Elizabeth, wife of Samuel Mitchell Ignored my Elizabeth and suggested Elizabeth Penglase as the mother of Catherine Mitchell. Elizabeth Penglase was born in 1698 in Kittery Maine, but with at London England birth/baptism attached to the record. Also shows her father as Christopher Mitchell and two marriages to her husband. Tree is very confused and conflated.
Susanna Koob Ignored Susanna who is proven and suggested replacement with Anna Margaretha Kirsch with only source being “Ancestry Family Trees.” No DNA matches, so how was this done, exactly?
John Herrell Ignored my John and substituted John Isaac Herrell, incorrectly from a different location, with no documentation.
John Herrell’s father Because John Herrell was incorrectly substituted, so is his father, shown as Davie Harrell.
Francois LaFaille’s father Suggested Jean Francois LaBelle who did not live in the right location to be the parent of Francoise LaFaille, nor is the surname correct.
Francois LaFaille’s mother Suggested Marie Genevieve Auger Baron who as the mother of Francois LaFaille, who was the wife of Jean Francois LaBelle.
Jacques De Foret Ignored proven ancestor, Jacques de Foret and replaced with Bonaventure Foret who did not live where my ancestor lived.

Evaluation

If you are looking for close cousins and know your tree well, you may well find some individuals with whom to collaborate based on the grouping of DNA matching descendants by ancestor. Perhaps you’ll be fortunate and discover previously unknown family photos, history or stories.

The further back in time ThruLines reaches, the more problematic the frankentrees that are unrelated to DNA become.

The suggested “replacements” of known, proven, ancestors with incorrect ancestors are found in my tree as follows:

  • 1 individual at generation 4
  • 2 individuals at generation 5
  • 12 individuals at generation 6
  • 40 individuals at generation 7

Here’s the final scorekeeping chart.

Ancestors Number Comments
Total ancestors in 7 generations 254
Ancestors with no DNA matches 20 German immigrant line
Missing Ancestors 14 No ancestor cards at all
Ancestors from my Tree with Gathered Descendants 149 My ancestor is accurate. Ancestor of matches may or may not be accurate
Ancestors with Unknown Parents 9 Generally, missing parents of females with no surnames and no potential parents offered.
Potential Ancestors Already in Tree 5
Possibly Accurate Potential Ancestors 2
Correct Ancestors Replaced by Incorrect Potential Ancestors 55

By any measure, this is an abysmal report card relative to “Potential Ancestors,” with only 2 potential new ancestors that could be accurate and 55 wildfires that can never be extinguished – with gasoline thrown on, encouraged and propagated by Ancestry themselves. What a terrible example of stewardship. This is not just a disservice to me, but to the entire genealogy community. We should be striving for accuracy, not feeding the ‘gators and fertilizing Kudzu vines frankentrees.

Goals and Benefits

My goal with genetic genealogy, and genealogy as a whole, is fourfold, as shown in the following chart. The questions is, how does ThruLines help me achieve these goals?

Goal ThruLines
To confirm known ancestors through DNA

 

This is best achieved by segment matching which Ancestry does not provide, but less conclusive evidence can certainly be obtained through close matches and shared matches that match both me and close family members. Unfortunately, Circles which is a form of genetic networks would provide additional confirmation but is being discontinued.
To document the lives of my ancestors accurately for future generations

 

ThruLines encourages the propagation of erroneous trees by suggesting them, by linking to them, and by failing to use any discernible quality measure. A quality tree is NOT a tree with conflicting sources about the same event, the same timeframe or unreliable sources such as “Ancestry Family Trees.” We, as individuals, can’t put these fires out as fast as Ancestry flames them, especially if quality trees are discounted for larger “scavenged” trees. Size does not = accuracy.
To break through brick walls

 

The two individuals that I have yet to research, as well as perhaps viewing trees for others whose DNA I match and share a common ancestor may be illuminating. It would be difficult to sift through the chaff for a newer genealogist.
To reconstruct and paint the DNA of my ancestors For this, I need at least segment data, if not a chromosome browser. I hope that Ancestry customers will transfer their DNA files to FamilyTreeDNA, MyHeritage and GedMatch to reap the added advantages of the tools at those sites – including the availability of segment information and the resulting confirmation ability.

ThruLines Recommendations

The “Potential Ancestor” feature could have been, and still can be presented in an entirely different way, facilitating responsible genealogy, including the following:

  1. Extremely visible and repeated warnings cautioning that ThruLines are not definitive, only hints and MUST BE VERIFIED with research.
  2. Do not ignore the ancestor in the customer’s tree.
  3. Providing “suggestions” to look at alternate ancestors or trees for additional information for ancestors, not doling out “potential ancestors” to replace your existing ancestors.
  4. Implementing artificial intelligence (machine learning) for accuracy including factors such as looking for multiple births in various locations (a person can only be born once), cobbled together frankentrees, multiple marriages at the same time in different places, births too late or early in the lives of potential parents, and more red flag factors that should down-weight trees as being “recommendation worthy.”
  5. Sharing with the customer why these trees were considered as recommendation worthy, similar to the MyHeritage confidence factor and side-by-side comparisons.
  6. Eliminating “Ancestry Trees,” IGI records and other similar “word of mouth” types of sources as being “recommendation worthy.”
  7. The ability to “dismiss” a “Potential Ancestor” suggestion and for that dismissal to be part of the AI learning process relative to future recommendations.
  8. Ability to group ThruLines, such as by categories: Dismiss (inaccurate), Accurate and processed, Reviewed but unknown accuracy, In Process, New and not yet reviewed, etc.
  9. Restoration of shared ancestor hints.
  10. Fix bug in common ancestors causing no matches with common ancestors to be found, which I would presume is supposed to replace Shared Ancestor Hints.
  11. Permanently archiving Circles and NADs.
  12. If the Circles must be replaced, find another way to provide a genetic network that includes people who descend from the same ancestor, have DNA tested and match some of the people in the Circle or NAD but not everyone.
  13. The ability to know when looking at a tree of a descendant of an ancestor if they have tested, and if so, if they match you.
  14. Much more adequate product testing before release. By any measure, this release has been miserable and was not adequately tested in advance. No one expects new code to be bug-free, but this is unacceptable.

Ancestry, I hope you’re listening, cause the ‘gators are circling and you need to help us escape from this mess you created.
