Ancestors: What Constitutes Proof?

All genealogists should be asking this question for every single relationship between people in their trees – or at least for every person that they claim as an ancestor. The answer differs a bit when you introduce DNA into the equation, so let’s discuss this topic.

It’s easier to begin by telling you what proof IS NOT, rather than what proof is.

What is Proof, Anyway?

First of all, what exactly do we mean by proof? Proof means proof of a relationship, which has to be proven before you can prove a specific ancestor is yours. It’s a two-step process.

If you’re asking whether those two things are one and the same, the answer is no, they are not. Let me give you a quick example.

You can have proof that you descend from the family of a specific couple, but you may not know which child of that couple you descend from. In one case, my ancestor is listed as an heir, being a grandchild, but the suit doesn’t say which of the man’s children is the parent of my ancestor. So frustrating!

Conversely, you may know that you descend from a specific ancestor, but not which of his multiple wives you descend from.

You may know that your ancestor descends from one of multiple sons of a particular man, but not know which son.

Therefore, proof of a relationship is not necessarily proof that a particular person is your ancestor.

Not Proof of an Ancestor

OK, so what’s NOT proof? Here are a dozen of the most common items – and there are surely more!

  1. Proof is not a DNA match alone. You can match as a result of ancestors on any number of lines, known or unknown.
  2. Proof is not an oral history, no matter how much you want to believe it or who said it. Oral history is a good starting point, not an end point.
  3. Proof is not, not, 1000 times NOT someone else’s tree. A tree should be considered a hint, nothing more.
  4. Proof is not a book without corresponding evidence that can be independently corroborated. Being in print does not make it so, people make mistakes and new information surfaces.
  5. Proof is not a man by the name of Jr., meaning that he is the son of a man by the same name with the suffix of Sr. Sr. often means older and Jr. means younger, but not necessarily related. Yes, this has bitten me.
  6. Proof of a father/son relationship is not two men with the same name in the same location.
  7. Proof is not a Y DNA match, at least not without additional information or evidence, although it’s a great hint!
  8. Proof is not an autosomal DNA match, unless it is an extremely close match and even then you (probably) need additional information. For example, if you have a half-sibling match, you need additional information to determine which parent’s side.
  9. Proof is not an Ancestry Circle, at least not without additional information.
  10. Proof is not similar or even identical ethnicity, or lack thereof.
  11. Proof is not a “DNA Proven” icon, anyplace.
  12. Proof is not a will or other document, at least not alone, and not without evidence that a person by the same name as the child is the RIGHT person.

I learned many of these NOTS or KNOTS as I prefer to call them, because that’s what they tie me in, by ugly experience. I began genealogy before there were proof standards, let alone the GPS (Genealogical Proof Standard). DNA adds yet another dimension to existing paper standards and is an important aspect of the requirement for a “reasonably exhaustive search.” In fact, there is no reason NOT to include DNA and I would suggest that any genealogical search is not complete without including genetic evidence.

Proof Is a Two-Way Street

Using traditional genealogy, genealogists must be able to prove not only that an ancestor had a child by a specific name, but that the person you believe is the child, is indeed the child of that ancestor.

Let me use an example of Daniel, the son of one Philip Jacob Miller in Washington County, Maryland in 1783.

The tax list shows Philip J. Miller, 15 entries from the bottom of the page, shown below. It also shows “Daniel Miller of Philip” 6 entries from the bottom, and it’s our lucky day because the tax list says that Daniel is Philip’s son.

But wait, there’s another Daniel, the bottom entry. If you were to look on the next page, you would also notice that there’s a Philip Miller who does not own any land.

What we have here is:

  • Philip J. Miller, with land
  • Daniel, son of Philip, no land
  • Daniel, no father listed, land
  • Philip, no land

This just got complex. We need to know which Philip is Daniel’s father and which Daniel is which Philip’s son.

Establishing proof requires more than this one resource.

The great news about this tax list is that it tells us how much land Philip J. Miller owned, and utilizing other resources such as deeds and surveys, we can establish which Philip J. Miller owned this land, and that his name was indeed Philip Jacob Miller. This is important because not only is there another Philip, who, by the way, is NOT the son of Philip Jacob Miller (knot #6 above), there is also another Jacob Miller, who is NOT Philip Jacob Miller and who isn’t even related to him on the Miller line, according to the Y DNA of both men’s descendants.

How would we prove that Philip Jacob Miller is the father of Daniel Miller? We’d have to follow both men backward and forward in time, together. We have great clues – land ownership or lack thereof.

In this case, Philip Jacob Miller eventually sells his land. Philip Jacob Miller also has a Bible, which is how we know that there is no son named Philip. Philip Jacob’s son, Daniel leaves with his brother David, also on this tax list, travels to another location before the family is reunited after moving to Kentucky years later, where Philip Jacob Miller dies with a will. All of his heirs sign property deeds during probate, including heirs back in Frederick and Washington County, Maryland. There is enough evidence from multiple sources to tie these various family members from multiple locations conclusively together, providing two way proof.

We must be able to prove that not only did Philip Jacob Miller have a son Daniel, but that a specific Daniel is the son of that particular Philip Jacob Miller. Then, we must repeat that exact step every generation to the present to prove that Philip Jacob Miller is our ancestor.

In other words, we have a chain of progressive evidence that taken together provides conclusive proof that these two men are BELIEVED to be related. What? Believed? Don’t we have proof now?

I say believed, because we still have issues like unknown parentage, by whatever term you wish to call it, NPE (nonpaternal event, nonparental event,) or MP (misattributed parentage,) MPE (misattributed paternal or parental event) or either traditional or undocumented adoptions. Some NPEs weren’t unknown at the time and are results of situations like a child taking a step-parent’s surname – but generations later – having been forgotten or undocumented for descendants, the result is the same. They aren’t related biologically in the way we think they are.

The Big Maybe

At this point, we believe we have the Philips, Philip Jacobs and Daniels sorted correctly relative to my specific line. We know, according to documentation, that Daniel is the son of Philip Jacob, but what if MY ancestor Daniel ISN’T the son of Philip Jacob Miller?

  • What if MY ancestor Daniel just happens to have the name Daniel Miller and lives in the same geography as Philip Jacob Miller, or his actual son Daniel, and I’ve gotten them confused?
  • What if MY ancestor Daniel Miller isn’t actually my ancestor after all, for any number of reasons that happened between when he lived and died (1755-1822) and my birth.

If you think I’m being facetious about this, I’m not. Not long after I wrote the article about my ancestor Daniel Miller, we discovered another Daniel Miller, living in the same location, also descended from the same family as evidenced by BOTH Y and autosomal DNA. In fact, there were 12 Daniel Millers I had to sort through in addition to the second Daniel on the 1783 tax list. Yes, apparently Daniel was a very popular name in the Miller family and yes, there were several male sons of immigrant Johann Michael Muller/Miller who procreated quite successfully.

Enter DNA

If DNA evidence wasn’t already a factor in this equation, it now must come into play.

In order to prove that Philip Jacob Miller is my ancestor, I must prove that I’m actually related to him. Of course, the methodology to do that can be approached in multiple ways – and sometimes MUST be approached using different tools.

Let’s use an example that actually occurred in another line. Two males, Thomas and Marcus Younger, were found together in Halifax County, Virginia, right after the Revolutionary War. They both had moved from Essex County, and they consistently were involved in each other’s lives as long as they both lived. They lived just a couple miles apart, witnessed documents for each other, and until DNA testing it was believed that Marcus was the younger brother of Thomas.

We know that Marcus was not Thomas’s son, because he was not in Thomas’s will, but Marcus and his son John both witnessed Thomas’s will. In that time and place, a family member did not witness a will unless it was a will hastily constructed as a person was dying. Thomas wrote his will 2 years before it was probated.

However, with the advent of DNA testing, we learned that the two men’s descendants did not carry the same Y DNA – not even the same haplogroup – so they do not share a common paternal ancestor.

Needless to say, this really threw a monkey wrench into our neat and tidy family story.

Later, the will of Thomas’s father, Alexander, was discovered, in which Marcus was not listed (not to mention that Alexander died before Marcus was born,) and, Thomas became the guardian of his three sisters.

Eventually, via autosomal DNA, we proved that indeed, Marcus’s descendants are related to Thomas’s descendants as well as other descendants of Thomas’s parents. We have a proven relationship, but not a specifically proven ancestor. In other words, we know that Marcus is related to both Thomas and Alexander, we just don’t know exactly how.

Unfortunately, Marcus only had one son, so we can’t confirm Marcus’s Y DNA through a second line. We also have some wives missing from the equation, so there is a possibility that either Marcus’s wife, or his unknown biological father’s family was otherwise related to Alexander’s line.

So, here’s the bottom line – we believe, based on various pieces of compelling but not conclusive evidence that Marcus is the illegitimate child of one of Thomas’s unmarried sisters, who died, which is why Marcus is clearly close to Thomas, shares the same surname, but not the Y DNA. In fact, it’s likely that Marcus was raised in Thomas’s household.

  • It’s entirely possible that if I incorrectly listed Thomas as Marcus’s father on Ancestry, as many have, that I would be placed in a Thomas circle, because Ancestry forms circles if your autosomal DNA matches and you show a common ancestor in your trees. This is why inclusion in a circle doesn’t genetically confirm an ancestor without additional information. It confirms a genetic relationship, but not how a person is related.
  • It’s entirely possible that even though Marcus’s Y DNA doesn’t match the proven Y DNA of Thomas, that Marcus is still closely related to Thomas – such as Marcus’s uncle. That’s why Marcus’s descendants match both Thomas’s and Alexander’s descendants through autosomal testing. However, without Y DNA testing, we would never know that they don’t share a paternal line.
  • It’s entirely possible that if Marcus was supposed, on paper, to be Thomas’s child, but was fathered by another man, such as his wife’s first husband, I would still be in the circle attributed to both Thomas and his wife, by virtue of the fact that I match DNA of Thomas’s descendants through Thomas’s wife. This is your classic step-father situation.

Paper is Not Proof

As genealogists, we became so used to paper documentation constituting proof that it’s a blow when that paper proves to be irrelevant, especially when we’ve hung our genealogical hat on that “proof” for years, sometimes decades.

The perfect example is an adoption. Today, most adoptions are through a court of law, but in the past, a functional adoption happened when someone, for whatever reason, took another child to raise.

The history of that “adoption” although not secret when it happened, became lost in time, and the child is believed to be the child of the couple who raised them. The adoption can actually be a step-parent situation, and the child may carry the step-father’s surname but his own father’s Y DNA, or it can be a situation where a relative or unrelated couple raised the child for some unknown reason.

Today, all paper genealogy needs to be corroborated by DNA evidence.

DNA evidence can be some combination of:

  • Y DNA
  • Autosomal DNA
  • Mitochondrial DNA

How Much Proof is Enough?

One of my favorite saying is “you don’t know what you don’t know.”

People often ask:

  1. If they match someone autosomally who shares the same ancestor, do they really need to prove that line through Y or mitochondrial DNA?
  2. Do they really need to match multiple people?
  3. Do they really need to compare segments?

The answers to these is a resounding, “it depends.”

It depends on the circumstances, the length of time back to the common ancestor, and how comfortable you are not knowing.

Relative to question 1 about autosomal plus Y DNA, think about Marcus Younger.  Without the Y DNA, we would have no idea that his descendant’s Y DNA didn’t match the Thomas Younger line. Suddenly, Marcus not being included in either Thomas nor Alexander’s will makes sense.

Relative to question 2 about matching multiple people, the first cousin we tested to determine whether it was me or my brother that was not the child of our father turned out to have different Y DNA than expected. Thank goodness we tested multiple people, including autosomal when it became available.

Relative to question 3 about comparing segments, every matching segment has its own unique history. I’ve encountered several situations where I match someone on one segment from one ancestor, and another segment from an entirely different line. The only way to determine this is by comparing and triangulating individual segments.

I’ve been bitten so many times by thinking I knew something that turned out to be incorrect that I want every single proof point that I can obtain to eliminate the possibility of error – especially multiple kinds of DNA proof. There are some things that ONLY DNA can reveal.

I want:

  • Traditional documentary evidence for every generation to establish the actual paper trail that proves that the child descends from the proper parents.
  • Y DNA to prove the son is the son of the father and to learn about the deeper family history. For example, my Lentz line descends from the Yamnaya culture, something I would never have known without the Big Y DNA test.
  • Mitochondrial DNA to prove that the mother is the actual mother of the child, if possible, not an unknown earlier or later wife, and to learn about the deeper family history. Elizabeth Mehlheimer’s mitochondrial DNA is Scandinavian – before her ancestors are found in Germany.
  • Autosomal DNA to prove that the paper lineage connecting me to the ancestor is correct and the line is not disrupted by a previously unknown adoption of some description.

I attempt to gather the Y and mitochondrial DNA haplogroup of every ancestor in my direct line if possible and confirm using autosomal DNA.

Yes, my personal proof standard is tough, but I suggest that you at least ask these questions when you evaluate documentation or see someone claim that they are “DNA proven” to an ancestor. What, exactly, does that mean and what do they believe constitutes proof? Do they have that proof, and are they willing to share it with you?

Genealogical Proofs Table

The example table below is designed to be used to document the sources of proof that the individual listed under the name column is in fact the child of the father and mother shown. Proofs may vary and could be personal knowledge (someone you knew within your lifetime), a Bible, a will, a deed, an obituary, death certificate, a church baptismal document, a pension application, census records, etc. DNA confirmation is needed in addition to paper documentation. The two types of proof go hand in hand.

Proof is a Pain!

So now that we’ve discussed what proof is not, and what types of records constitute proof, you may be thinking to yourself that proof is a pain in the behind. Indeed, it is, but without sufficient proof, you may literally be doing someone else’s genealogy or the genealogy of an ancestor that’s not your own. Trust me, that’s infinitely more painful.

I hate sawing branches off of my own tree. If I have to do it, the sooner I make the discovery and get it over with, the better.

Been there, done that, and really, I don’t want the t-shirt.

There is never such a thing as “too much” proof, but there is certainly too little. We are fortunate to live in a time when not only are historical records available, but the record passed by our ancestors inside our very cells tells their story. Use every tool and every type of DNA at your disposal! Otherwise, you get the t-shirt:)

Why Different Haplogroup Results?

“Why do vendors give me different haplogroups?”

This questions often comes up when people test with different vendors and receive different haplogroup results for both Y and mitochondrial DNA.

If you need a quick refresher on who carries which types of DNA, read 4 Kinds of DNA for Genetic Genealogy.

You’re the same person, right, so why would you receive different answers from different testing companies, and which answer is actually right?

The answer is pretty straightforward, conceptually – having to do with how vendors test and interpret your DNA.

Different companies test different pieces of your DNA, depending on:

  • The type of chip the company is using for testing
  • The way they have programmed the chip
  • The version of the reference “tree” they are using to assign haplogroups
  • The level they have decided to report

Therefore, their haplogroups reported may vary, and some may be more exact than others. Occasionally, a vendor outside the major testers is simply wrong.

Not All Tests are Created Equal

All haplogroups carry interesting information and can be at least somewhat genealogically useful. For example, haplogroups alone can tell you if your direct line DNA (paternal or matrilineal) is probably European, Asian, African or Native American. Note the word probably. This too may be subject to interpretation.

A basic haplogroup can rule out a genealogical match through a specific branch, but can’t confirm a genealogical match. You need to compare specific DNA locations not provided with haplogroup testing alone for genealogical matching. Plus you’ll need to add genealogical records where possible.

Let’s look at two examples.

Mitochondrial DNA

Your mitochondrial DNA is inherited from your mother’s direct line, on up you tree until you run out of mothers.  So, you, your mother, her mother, her mother…etc.

The red circles show the mitochondrial lineage in the pedigree chart, below.

If your mitochondrial haplogroup is H1a, for example, then your base haplogroup is “H”, the first branch is “1” and the next smaller branch is “a.”

Therefore, if you don’t match at H, your base haplogroup, you aren’t a possible match on that genealogical line. In other words, if you are H1a, or H plus anything, you can’t match on the direct matrilineal line of someone who is J1a, or J plus anything. H and J are different base haplogroups who haven’t shared a common ancestor in tens of thousands of years.

You can, however, potentially be related on any other line – just not on this specific line.

If your haplogroup does match, even exactly, that doesn’t mean you are related in a genealogically relevant timeframe. It means you share an ancestor, but that common ancestor may be back hundreds, thousands or even tens of thousands of years.

The further downstream, the younger the branches.  “H” is the oldest, then “1,” then “a” is the youngest.

Some companies might just test the locations for H, some for H1 and some for H1a.  Of course, there are even more haplogroups, like H1a2a. New, more refined haplogroups are discovered with each new version of the mitochondrial reference tree.

The only company that tests your haplogroup all the way to the end, meaning the most refined test possible to give you your complete haplogroup and all mutations, is Family Tree DNA with their mtFull Sequence test.

A quick comparison of my mitochondrial DNA at the following three vendors shows the following:

23andMe Living DNA Family Tree DNA Full Seqence
J1c2 J1c J1c2f

With Family Tree DNA’s full sequence test, you’ll receive your full haplogroup along with matching to other people who have taken mitochondrial DNA tests. They are the only vendor to offer Y and mitochondrial matching, because they are the only vendor that tests at that level.

Y DNA

Y DNA operates on the same principle. Specific locations called SNPs are tested by companies like 23andMe and Living DNA to provide customers with a branch level haplogroup. You don’t receive matching with these types of tests.

Just like with mitochondrial DNA, a basic branch level test can eliminate a match on the direct paternal (surname) branch but can’t confirm the genealogical match.

If your haplogroup branch is E-M2 and someone else’s is R-M269, you can’t share a common paternal ancestor because your base haplogroups don’t match, meaning E and R.

You can share an ancestor on any other line, just not on the direct Y line.

The blue squares show the Y DNA lineage on the pedigree chart below.

Family Tree DNA predicts your haplogroup for free if you take the 37, 67 or 111 marker Y-DNA STR test, but if you take the Big Y-500, your Y chromosome is completely tested and your haplogroup defined to the most refined level possible (often called your terminal SNP) – including mutations that may exist in only very few people. You also receive matching to other testers (with any Y test) which can be very genealogically relevant, plus bonus Y STR markers with the Y-500.

OK, But Why Do Different Companies Give Me Different Haplogroup Results?

Great question.

For this example, let’s say your haplogroup is H1a2a.

Let’s say that Company 1 uses a chip that they’ve programmed to test to the H1a level of haplogroup H1a2a.

Let’s say that Company 2 uses a chip that they’ve programmed to test to the H1 level of haplogroup H1a2a.

Let’s say that you take the full sequence test with Family Tree DNA and they fully test all 15,659 locations of your mitochondria and determine that you are H1a2a.

Company 1 will report your mitochondrial haplogroup as H1a, Company 2 as H1 and Family Tree DNA as H1a2a.

With mitochondrial DNA, you can at least see some consist pathway in naming practices, meaning H, H1, H1a, etc., so you can tell that you’re on the same branch.

With Y DNA, the only consistent part is the base haplogroup.

With Y DNA, let’s say that Company 1 programs their chip to test for specific SNP  locations, and they return a Y DNA haplogroup of R-L21.

Company 2 programs their chip to test for fewer or different locations and they return a Y DNA haplogroup of R-M269.

You purchase a Big Y-500 test at Family Tree DNA, and they return your haplogroup as R-CTS3386.

All three haplogroups can be correct, as far as they go. It’s just that they don’t test the same distance down the Y chromosome tree.

R-M269, R-L21 and R-CTS3386 are all increasingly smaller branches on the Y haplotree.

Furthermore, for both Y and mitochondrial DNA, there is always a remote possibility that a critical location won’t be able to be read in your DNA sample that might affect your haplogroup.

Obtaining Your Haplogroup

I strongly encourage people to test with and upload to only well-known major companies or organizations. Some companies provide haplogroup information that is simply wrong.

Companies that I am comfortable with relative to haplogroups include:

Neither MyHeritage nor Ancestry provide Y or mitochondrial haplogroups.

The chart below shows the various vendor offerings, including Y and mitochondrial DNA matching.

Company Offerings Matching
Family Tree DNA – Y DNA Y haplogroup is estimated with STR test. Haplogroup provided to most refined level possible with Big Y-500 test. Individual SNP tests also available. Yes
Family Tree DNA – mitochondrial At least base haplogroup provided with mtPlus test, plus more if possible, but full haplogroup plus additional mutations provided with mtFull Sequence test. Yes
Genographic Project More than base haplogroup for both Y and mitochondrial, but not full haplogroup on either. No
23andMe More than base haplogroup for both Y and mitochondrial, but not full haplogroup on either. No
Living DNA More than base haplogroup for both Y and mitochondrial, but not full haplogroup on either. No

Pass the DNA, Please

I know that sometimes understanding who inherits what kind of DNA from whom can be confusing, especially with four kinds of DNA to keep track of.

Let’s Make This Easy

In a nutshell:

  • Y DNA is passed from the father to male children only (blue boxes). This is the paternal surname line.
  • Mitochondrial DNA is passed from women to all of their children, but only females pass it on (red circles).

  • Half of each parent’s autosomal DNA (chromosomes 1-22) inherited from ancestral lines, meaning all lines shown above, is passed to each child – but not the same exact half is passed to different children.
  • The X chromosome has a distinct inheritance pattern that is helpful to genealogists, but is often confused with mitochondrial DNA.

You can read about the X chromosome’s unique inheritance path in the article X Matching and Mitochondrial DNA is Not the Same Thing, along with some helpful fan charts.

Let’s look at this a different way.

Mother Passes DNA to Children

Father Passes DNA to Children

Ordering Tests

You can order any of the various DNA tests, including matching to other testers, from the following vendors:

I recommend that you test with or transfer to each of the vendors.

Autosomal Transfers

Have you already taken an autosomal DNA test and want to transfer between vendors? Here’s a handy-dandy chart for you.

Note that while Family Tree DNA does accept the Ancestry V2 chip, as well as the 23andMe V4 chip, because they are incompatible platforms, you’ll only see your closest matches, meaning about 20% of the total matches you would receive if you tested on Family Tree DNA’s own chip. For that reason, I generally recommend testing at Family Tree DNA unless you tested on an earlier chip version at one of those vendors.

For more information about transfers, including when the various chips were in use, please read Autosomal DNA Transfers – Which Companies Accept Which Tests?

DNA Painter – Chromosome Sudoku for Genetic Genealogy Addicts

Not long ago, Jonny Perl introduced the free online tool, DNA Painter, designed to paint your chromosomes. I didn’t get around to trying this right away, but had I realized just how much fun I would have, I would have started sooner.

Fittingly, Jonny, pictured above, won the RootsTech Innovation award this year for DNA Painter – and I must say, it’s quite well-deserved.

Congratulations Jonny!

  • This is the first of four articles about DNA Painter. In this article, we’ll talk about how to use the tool, and how to get started.
  • The second article talks about mining your matches at the various vendors for paintable segments with instructions for how to do that accurately with each vendor.
  • In the third article, we’ll walk through an analysis of my painted segments, so you can too – and know how to spot revelations.
  • The fourth article explains how I solved a long-standing mystery that was driving me crazy. If you have a relatively close mystery person in your DNA match list that you can’t figure out quite where they fit, this article is written just for you!

I’ll tell you right now, I haven’t had this much fun in a long time!

Want to hear the best part? You don’t have to triangulate. DNA painting is “self-triangulating.” Yes, really!

Let’s get started!

Introducing DNA Painter

To begin to use DNA Painter, you’ll need to set up a free account at www.dnapainter.com.

Read the instructions and create your profile.

Jonny provides an overview.  Don’t get so excited that you skip this, or you won’t know how to paint correctly. You don’t need to be Picasso, but taking a few minutes up front will save you mistakes and frustration later.

Blaine Bettinger recorded a YouTube video discussing how to use DNA Painter to paint your chromosomes to identify and attribute particular segments to specific ancestors. It includes a mini-lesson on chromosome matching.

I strongly suggest you take time to watch Blaine’s video from the beginning. For some reason, this link drops into the video near the end, but just slide the red bar back to the beginning.

Get Started

Here’s my blank, naked chromosomes. Notice for every chromosome, you see a blue paternal “half” and a pink maternal “half.” That’s because everyone gets half of their autosomal DNA from their father, and the other half from their mother.

Looking at my own chromosome painting today, below, it’s incredibly exciting for me to see 57% of my DNA painted, attributed to 77 couples and one endogamous group, Acadians. This took me a month or so working off and on.

At the end of the day, this is often how I rewarded myself! The only problem it that it has been difficult to go to bed.

Comparatively, I’ve been working on my DNA match spreadsheet, attributing segments to ancestors now for 5 or 6 years, and I’ve never been able to see this information visually like this before. This view of my ancestrally painted chromosomes is so rewarding!

Who To Map

DNA Painter is not the kind of tool where you upload your results, it’s a tool where you selectively paint specific segments of matches – meaning segments on which you match particular people with known common ancestors.

How do you know who is a good candidate to map?

I began with painting my closest matches with whom I could identify the common ancestor.

Not only will painting your largest matches be rewarding as you harvest low-hanging-fruit, it will help you determine if you actually have identified the correct DNA for later matches being attributed to a specific genealogical line. In other words, mapping these larger known segments will help you identify false positives when you have no other yardstick.

Your First Painting

I’m opening a new profile in DNA Painter to demonstrate the steps in painting along with hints that I’ve learned along the way.

I’m going to utilize my cousin, Cheryl, whom I match closely at Family Tree DNA. If you don’t know how to use the Family Tree DNA autosomal tools, click here.

Cheryl is my first cousin once removed, so we share a significant amount of DNA.

I’ve selected Cheryl on my match list, checked her match box, and then clicked on the Chromosome Browser in order to view our segment matching information.

You can see on the chromosome browser that I share quite a bit of DNA with Cheryl.

At the top of the chromosome browser, click on “View this data in a table.”

Highlight and copy all of the segments for Cheryl. I only use 7cM segments or higher at DNA Painter, so you don’t have to copy the data in the rows below your last match at that level. DNA Painter takes care of stripping out all the extraneous stuff.

Paint a New Match

At DNA Painter, after you have your profile set up, click on “Paint a New Match.”

Simply paste the segment data into the box in the window that pops up. DNA Painter takes care of removing the header information as well as segments that are too small.

You can click on “overlay these segments” to “test” a fit, but I haven’t really found a good use for that, because I’m only painting segments I’m confident about and I know which side, maternal or paternal, the match is on based on the known relative.

Click on “save match now” in the bottom right corner.

In the Save Match popup, shown above, I utilize the fields as follows.

I enter the name of my DNA match, followed by their relationship to me, followed by the source of the match. In this case, “Cheryl <lastname>, 1C1R, FTDNA”

In the “Segment/Match Notes” I list how the match descends from the common ancestral couple, a GedMatch ID if known, and anything else pertinent including other potential ancestral lines in common. This means that I list every generation beginning with the common ancestral couple and ending with the tester.

Hiram Ferverda and Eva Miller, Roscoe, Cheryl, GedMatch Txxxxxx

You’ll wind up eventually rethinking some of your segment assignments to particular ancestors and you’ll want as much information here about this match as possible.

Moving to the next field, in the “Ancestors Name,” I utilize the couples name, because at this point, you can’t tell which of the two people actually contributed the DNA segment, or if part is from one ancestor of the couple and part is from the other. If the male ancestor is a Sr. or Jr., or is otherwise difficult to tell apart from your other ancestors, I suggest entering a birth year by his name. This is your selection list for later painting segments from the same ancestor, so you want to be sure you can tell the generations apart.

Next, you’ll select the maternal or paternal side of your family. Change the color if you don’t like the one pre-selected to assign to segments descending from that couple. Originally, I was going to have pinks or light colors for maternal, and blues or darker for paternal, but I quickly discovered that scheme didn’t work well, and I had more ancestors than I could ever have imagined whose DNA I am be able to map and paint.

Therefore, pick contrasting colors. You can use each color on each half, meaning maternal and paternal, since the segments will be painted on different halves of the chromosome.

In the “Notes for This Group,” I add more information for the couple such as birth and death dates and location if I know or am likely to forget.

Click “save.”

Here you go!  Isn’t this fun!!!! Cheryl’s segments that match mine are painted onto my chromosomes!

At the right, your ancestor key appears with each ancestor to whom you’ve assigned a color key.

So far, I only have one!

Want to paint another group of segments?

Let’s paint Cheryl’s brother.

Following the same sequence, I paint Donald’s DNA, but this time, I select “Or link these segments to an ancestor I’ve added before.”

I select Hiram Ferverda, Eva Miller and save. The segments that I have in common with Cheryl and/or Don will now be displayed on each chromosome.

Looking at chromosome 1, you can see that I match Cheryl and Don on the same segment at the beginning of the chromosome, but received two different segments of DNA on a different portion of chromosome 1, further to the right.

As one last example, I added the DNA from two known cousins, Rex and Maxine, who descend a couple generations further back in time through more distant ancestors in the same line – one maternal and one paternal.

Click on the chromosome number to expand to see all of the painted segments

You can see, looking at chromosome 3 that Cheryl and Don match me on a significant amount of the same large pink segment plus a smaller pink segment at the end

Rex (yellow) and Maxine (blue) both match me on different parts of the chromosome. It looks like there is a small amount of overlap between Rex and Maxine which is certainly feasible, because Jacob Lentz, the ancestor that Maxine descends from is ancestral to the couple that Rex descends from.

By utilizing known matches, and mapping, we can see segments that move us back in time, telling us from which ancestor that portion of the segment descends.

For example, if the blue segment was directly aligned with one of the pink segments, then we would know that the blue portion of the pink segment descended from Jacob Lentz and Fredericka Reuhl.

This is the most awesome, extremely addictive game of ancestor Sukoku ever.

Wanna play???

Here’s how to prepare for my next article where we’ll utilize the various vendor matches to begin painting.

Download and Upload Your Autosomal Files

You’ll want to have your DNA at the most vendor locations possible so you can find all your matches that can be attributed to known relatives and ancestors. You never know who is going to test at which vendor, and the only way to find out is to have your DNA there too.

For each vendor, I’ve provided a mini-tutorial on how to maximize your testing and transfers both monetarily and for maximum matching effect, or you can read an article here that explains more.

There’s also a cheat sheet for transfer strategies at the end of this article.

A technique called imputation is mentioned below, so you may want to read about imputation here. MyHeritage’s initial offering utilizing imputation was problem plagued but has since improved significantly.

Ancestry

To Ancestry – There’s no way to transfer files TO Ancestry, so you’ll need to test there to be in their database. You will also need at least a minimum subscription ($49) to utilize all of the Ancestry DNA features. You can see a with and without subscription feature comparison chart here.

From Ancestry – There is also no chromosome browser at Ancestry. In order to use DNA Painter, chromosome segment information is required, so if you test at Ancestry and want to paint your segments, you’ll need to download your DNA file to either or all of:

  • Family Tree DNA – partially compatible with the current Ancestry test chip format – transfer will provide you with your closest matches, 20-25% of the matches you would have if you tested at Family Tree DNA
  • MyHeritage – partially compatible, but uses imputation to infer additional genetic regions
  • GedMatch

My preference is to test at Ancestry, and then test at Family Tree DNA and upload the test results to MyHeritage. The Family Tree DNA and MyHeritage testing platforms are the same, so there is no incompatibility between the two.

Family Tree DNA

To Family Tree DNA – You can upload the following vendor files TO Family Tree DNA.  Matching is free, but to use the advanced tools, including ethnicity and the chromosome browser, you’ll need to pay the $19 unlock fee. That’s still significantly less than retesting, especially for files that are 100% compatible.

  • Ancestry – V1 files generated from before May 2016 are entirely compatible, V2 files from after May 2016 are partially compatible, providing between 20-25% of your matches, meaning your closest matches
  • 23andMe – V3 file from Dec 2010-Nov 2013 and V4 file from November 2013-August 2017 are compatible, the V5 platform file beginning in August 2017 is not compatible
  • MyHeritage – fully compatible

From Family Tree DNA – You can upload your Family Finder results to:

MyHeritage

To MyHeritage – You can upload the following files to MyHeritage:

  • Family Tree DNA – fully compatible
  • Ancestry – partially compatible but uses imputation to infer additional genetic regions
  • 23andMe – partially compatible but uses imputation to infer additional genetic regions

From MyHeritage – If you test at MyHeritage, you can upload your files to:

23andMe

To 23andMe – You cannot transfer TO 23andMe, so you’ll need to test there if you want to be in their database.

From 23andMe – If you tested at 23andMe, you can upload your files to the following vendors:

  • Family Tree DNA – V3 file from Dec 2010-Nov 2013 and V4 file from November 2013-August 2017 are compatible, the V5 chip beginning in August 2017 is not compatible
  • MyHeritage – 23andMe – partially compatible but uses imputation to infer additional genetic regions
  • GedMatch – V3 file from Dec 2010-Nov 2013 and V4 file from November 2013-August 2017 are compatible, the V5 chip beginning in August 2017 is only compatible in the Genesis sandbox area. V5 matching is not reliable. Files from other vendors are recommended for GedMatch unless you are matching against another V5 result.

GedMatch

GedMatch is a third-party site that accepts all of these vendors’ autosomal files, with a caveat that the 23andMe V5 kit matches very poorly and requires special handling. I don’t recommend using that kit at GedMatch unless you are matching against other 23andMe V5 kits.

I upload multiple kits to GedMatch and mark all but one for research only. This allows me to use my Ancestry kit to match with other Ancestry users for more accurate matches, my Family Tree DNA kit to other Family Tree DNA kits, and so forth. Not marking multiple kits for research means that you’ll appear more than once on other people’s match lists, and only your first 2000 matches are free. Marking all kits except one as research is a courtesy to others.

Recommended Testing Strategy for New Testers

  1. Test at Ancestry and download to GedMatch.
  2. Test at Family Tree DNA and upload to MyHeritage and GedMatch.
  3. Test at 23andMe and upload to GedMatch Genesis.
  4. At GedMatch, mark all except one kit as “research,” then utilize your kits from the same vendor for one-to-one comparisons.

Recommended Transfer Strategy

Of course, where you have, and haven’t already tested will impact your transfer strategy decision. I’ve prepared the following cheat sheet to be used in combination with the information discussed above.

*Unless you can transfer a 23andMe V3/V4 or an Ancestry V1 kit to Family Tree DNA, it’s better to test at Family Tree DNA. Ancestry V2 tests are only 20-25% compatible.

A transfer from Family Tree DNA to MyHeritage is best because those vendors are on the same platform and the tools at MyHeritage are free.

In my next article, we’ll discuss how to mine your matches at the various vendors to obtain accurate segments for chromosome painting – including a strategy for how to utilize Ancestry and Gedmatch together to identify at least some Ancestry segment matches.

So, for now, get ready by transferring your matches into whichever data bases they aren’t already in. The only data base where I couldn’t identify matches that I didn’t have elsewhere was at 23andMe. The rest were all there just waiting to be harvested!

DNA Love and Your “Big 8” – Plus Valentine’s Day Sales!

We’re approaching Valentine’s Day, and I’m reminded just how much I love genetic genealogy. I already loved genealogy before the genetic portion emerged. Since DNA has been added to our toolbox, I’m head over heels.

I can’t even begin to count the number of breakthroughs I’ve had using DNA. On EVERY LINE.

In order to further my own genealogy, I’ve purchased countless (I don’t want to count, truthfully) kits and tests for other people. I don’t regret any single one of those dollars, because they all helped ME. Yes, even kits that didn’t match helped me.

Why? Because they might have matched. Some did match. Some provide haplogroup information for my ”Big 8” meaning for all of my 8 great-grandparents.

Click to enlarge

As you can see, I still need to find test candidates for two of my great-grandparents to complete the “Big 8.”

My now-deceased aunt tested for the Margaret Claxton/Clarkson line before mitochondrial full sequencing was commercially available. When I wanted to upgrade her test to full sequence and autosomal, I couldn’t because the archived DNA quality was too poor. Now, I need to find another testing candidate to discover her full haplogroup aside from the rather generic H. Lesson learned – now I just order the whole shebang out the gate!

A second mitochondrial test that I need is for Evaline Miller, my Brethren great-grandmother.

Do You Qualify For a Free Test?

Shameless plug – If you descend from any of the following women through all females to the current generation, where testers can be either males or females, I have a free mitochondrial AND autosomal test for YOU at Family Tree DNA. Happy Valentine’s Day!

  • Margaret Claxton (1851-1920) Hancock Co, TN
  • Elizabeth Speaks (1832-1907) Hancock Co., TN
  • Ann McKee (1804/5-1850/50) Washington Co., VA, Lee Co., VA
  • Elizabeth, wife of Andrew McKee (1766-1814) Washington Co., VA
  • Evaline Miller (1857-1939) Elkhart Co., Indiana
  • Margaret Elizabeth Lentz (1822-1903) Montgomery Co., Ohio, Elkhart Co., Indiana
  • Fredericka Reuhle (1788-1863) Beutelsbach, Germany, Montgomery Co., Ohio
  • Dorothea Katharina Wolfin (b 1755) Beutelsbach, Germany
  • Dorothea Keubach (1729-1790) Endersbach, Germany, Beutelsbach, Germany

Let’s say you want to do the same thing, find people who are candidates to test for specific lines.

Finding Test Candidates

How might you find these people? Trees of autosomal DNA matches are a good choice. I mine my DNA matches at all vendors to see who might match me in the direct line needed to carry the Y or mitochondrial DNA of the desired ancestor. If someone has already DNA tested, they at least understand the subject and you’re not introducing the topic of DNA testing from scratch.

The three main testing vendors (along with GedMatch) each have a variety of tools to help find candidates.

  • Ancestry: Green leaf hints DNA+Tree Matching
  • Family Tree DNA: Phased maternal and paternal “bucketed” match results, trees and in-common surnames
  • MyHeritage: DNA+Tree Matching called SmartMatching
  • GedMatch: Search all GEDCOMs and GEDCOM 1 to All

As luck would have it, all three vendors are having Valentine’s Day DNA Sales too.

Valentine Day Sales and Testing Strategy

Now is a great time to test and transfer your autosomal DNA results for maximum matching.

Family Tree DNA

Family Tree DNA is having their “Sprinkle Some DNA Love” sale where the Family Finder autosomal test is on sale for $59.

If you want the option of Y, mitochondrial and autosomal, Family Tree DNA is the vendor to select, as they are the only vendor performing Y and mitochondrial testing and matching. You can purchase the Family Finder test today and add any of the other tests, either now or later. $59 is the least expensive price of all the vendors this holiday and you can transfer to MyHeritage and GedMatch for free!

MyHeritage

MyHeritage is on sale for $69 (or $59 if you purchase 2.) You can transfer Family Tree DNA kits to MyHeritage and vice versa without losing any quality or matches because Family Tree DNA’s lab runs the tests for MyHeritage. In fact, this is a great approach because transfers are free and you can fish in both ponds. Both vendors have advanced tools. MyHeritage tends to have European testers not in other data bases, so whether your transfer or test, you’ll want to be there if you have European heritage.

The transfer is free to Family Tree DNA, but there is a charge to unlock their advanced tools, so the best testing strategy would be to test at Family Tree DNA (where the test is less expensive) and transfer to MyHeritage. Total cost – $59 at Family Tree DNA where the total cost of testing first at MyHeritage and transferring to FTDNA is $88 (or $78 each if you purchase 2 kits.)

Ancestry

Ancestry’s test is also on sale for $69. You can transfer the Ancestry results to Family Tree DNA and MyHeritage, but the Ancestry test only covers about 25% of the same test locations as either Family Tree DNA or MyHeritage. As a result, at Family Tree DNA, you only receive your closest 20-25% of your matches and at MyHeritage, they utilize imputation to compensate for the shortcoming. Ancestry’s matching data base is quite large and their tools, though not as comprehensive as elsewhere, are easy to use.

You cannot transfer any results TO Ancestry, so my recommendation if you’re going to test at Ancestry would be to also test at Family Tree DNA and transfer your results to MyHeritage.

Of course, all three of these tests provide the much-sought-after ethnicity estimates.

Testing (and Money Saving) Strategy

Of the four vendors who provide autosomal matching, the comparative costs during the Valentine’s Day sale are as follows:

  • If you’re only going to make one purchase, you can purchase a kit for $59 at Family Tree DNA, have it available for upgrades and transfer to both MyHeritage and GedMatch for free.
  • You can test at Ancestry and Family Tree DNA, both, and transfer to MyHeritage and GedMatch for a total cost of $128 and be swimming in all the best ponds!
  • If you’re an adoptee or seeking an unknown parent, you’ll want to test at 23andMe as well. Their Ancestry Service kit is on sale for $79 now, but 23andMe has dropped to a distant 4th in terms of genetic genealogy.

How about buying a genetic genealogy valentine bouquet for someone you love!

Who Tests the X Chromosome?

Recently, someone asked which of the major DNA testing companies test the X chromosome and which ones use the X in matching. How does this difference influence the quality of our matches?

Vendor X in Download File Uses X in Matching X Included in Total cM Count
23andMe Yes Yes Yes
Family Tree DNA Yes Yes (if have a match on another chromosome) No
Ancestry Yes *No No
MyHeritage Yes No No
GedMatch N/A Separately No

*If Ancestry did utilize the X in matching, it wouldn’t benefit customers because Ancestry does not show segment information by chromosome.  In other words, no chromosome browser.

Family Tree DNA includes any size X match IF and only if the two people already match on a different chromosome.

GedMatch, of course, isn’t a vendor who does DNA testing, so they don’t provide download files.  They are solely on the receiving end.

X CentiMorgan Counts

Due to variations in the way vendors calculate matches and total cM counts, your mileage may vary a bit.

In other words, the 23andMe cM total, if an X match is involved, may be slightly more than a match between the same two people at Family Tree DNA, where the X match cM is not included in the cM total.

Conversely, you won’t show an X match with someone at Family Tree DNA if there isn’t also another segment on a different chromosome that matches.

In general, due to the thin spread of SNPs on the X chromosome, you will need, on average, a cM match that is twice as large as on other chromosomes to be considered of equal weight.

In other words, a 10 cM match on the X chromosome would only be genealogically equivalent to approximately a 5 cM match on any other chromosome.

X matches really can’t be evaluated by the same rules as other chromosomes due both to their SNP paucity and their inheritance path, which is why most vendors don’t include those segments in the total cM count.

X Matches

While including the X chromosome cM count is problematic, X matching can be a huge benefit because of the unique inheritance path of the X chromosome.

In the article, X Marks the Spot, we discussed the inheritance path of the X chromosome for both males and females. Females inherit an X chromosome from both father and mother, which recombines just like chromosomes 1-22.  However, men only inherit an X from their mother, because they inherit a Y from their father instead of the X.  Therefore, males will only inherit an X from their mother, and females will only inherit their father’s mother’s X chromosome.

Charting Companion software works with your genealogy software of choice to produce a lovely fan chart where the contributors of my X chromosome are charted in color, above. You can read more about Charting Companion here.

The great news is that if you and a match share a significant portion of the X chromosome, meaning more than 15 cM which reduces the likelihood of an identical by chance match, the common ancestor (on that segment) has to come from an ancestor in your direct X path.

I’m always excited to see with whom I share an X.  That piece of information alone helps me focus my ancestor detective efforts on a specific portion of my tree.

Some X segments can remain intact for generations and may be very old.  So don’t be surprised if the common ancestor of the X segment and another matching segment may not be the same ancestor.

Sorting by X

I wasn’t able to find a way to sort by X chromosome matches at 23andMe, but you can sort by the X at both Family Tree DNA and GedMatch.

At GedMatch, X matching shows on the one-to-many match page.  You can sort by either Total X cM or Largest X cM by using the up and down arrows, at right, below, in the X DNA columns.

After you identify an X match, be sure to run the X one-to-one match option to verify.

My GedMatch matches cause me to wonder if 23andMe is using a different reporting threshold for the X chromosome, because one of my matches at GedMatch is a close family member with no X match at 23andMe, but a total of 32 X cM and with a longest segment of 14 X cM at GedMatch.

That same individual matches me with the largest X segment of 14 cM at Family Tree DNA as well.

Family Tree DNA X Match Phasing

At Family Tree DNA, on your Family Finder matches page, just click on the X-Match header (at right, below) to bring all of your X matches to the top of your list.

If you have linked any kits of relatives to your tree, you will see numbers of phased kits on the maternal and paternal tabs with the red and blue male and female icons. In the example above, I have 3313 matches total, with 744 being paternal, 586 being maternal.

Next, click on the maternal or paternal tab to see only the people with X matches who match you on the  your maternal and paternal lines. Matches are automatically sorted into maternal and paternal “buckets” for you. Remember to check the size of the X match before deciding about relevance.

Who is your largest X match that you don’t already know?  Maybe you can find your common ancestor today.

Have fun!!!

2018 Resolution – Unveiling Hidden Evidence

I spent New Year’s Eve, doing what I’ve done for years on New Year’s Eve – celebrating by researching. In fact, it was at the stroke of midnight in 2005 that I ordered kit number 50,000 from Family Tree DNA.  Yes, I’m just that geeky and yes, I had to purchase several kits in a row to get number 50,000.

That kit went on to help immensely, as I used it to test an elderly cousin of my great-grandmother’s generation who took both the Y DNA test, and then, eventually, autosomal.

This year I made a wonderful discovery to mark the new year.  But first, let’s see how I did with last year’s resolution.

Last Year’s Resolution

Last year, I made 1 resolution. Just one – to complete another year’s worth of 52 Ancestor stories.

Now, that didn’t mean I had to do 52 in total.  It meant I had to be committed to this project throughout the year.  You know, unlike cleaning out that closet…or losing weight…or exercising more. Commitments that are abandoned almost as soon as they are made.

So, how did I do?

I published 37 stories.  I shudder to think how many words or even pages that was.  I’m ashamed to say that I plucked much of the “low hanging fruit” early on, so these were tough ancestors for an entire variety of reasons.

That’s not one article each week, but at least I’m making steady progress. And I must say that I couldn’t do it without a raft of helpers – all of whom I’m exceedingly grateful to.  Friends, professionals, cousins, DNA testers, blog subscribers and commenters – an unbelievable array of very kind souls who are willing to give of their time and share their results. Thank you each and every one!

Now, I’m thrilled to tell you that Amy Johnson Crow has revitalized the 52 Ancestor’s project.  It’s free and you can sign up here.  There’s no obligation, but Amy provides suggestions and a “gathering place” of sorts. Think of her as your genealogy cheerleader or coach. It’s so much easier with friends and teammates! I miss reading other people’s stories, but I won’t have to miss that much longer!

Randy Seaver (of Genea-Musings) and I will have company once again.  He’s the only other person that I’m aware of that has continued the 52 Ancestors project – and he has put me way to shame.  I do believe he published number 286 this week.  I keep hoping that some of his ancestors and some of mine are the same so I can piggyback on Randy’s research! I need an index! Randy, are you listening?

You might wonder why I enjoy this self-imposed deadline ancestor-writing so much.

It’s really quite simple.  It’s an incredible way to organize and sort through all of your accumulated research “stuff.”  I cherish the end product – documenting my ancestors lives with dates, compassion and history.  BUT, I absolutely hate parts of the research process – and the deadline (of sorts) gets me through those knotholes.

I absolutely love the DNA, and I really, REALLY like the feeling of breaking through brick walls.  It’s like I’m vindicating my ancestors and saving them from the eternal cutting room floor. DNA is an incredible tool to do just that and there are very few ancestors that I can’t learn something from their DNA, one way or another – Y, mtDNA,  autosomal and sometimes, all three.  And yes, DNA is in every one of my articles, one way or another. I want everyone to learn how to utilize DNA in the stories of their ancestor’s lives.  In many cases the DNA of theirs that we (and our cousins) carry is the only tangible thing left of them. We are wakling historical museums of our ancestral lines!

How Did You Do?

Not to bring up an awkward subject, but if you recall, I asked you if you had any genealogy resolutions for 2017?  How did you do?

Congratulations if you succeeded or made progress.

It’s OK if you didn’t quite make it. Don’t sweat last year.  It’s over and 2018 is a brand spanking new year.

New Year Equals New Opportunities

2018 is stacking up to be a wonderful year. There are already new matches arriving daily due to the Black Friday sales and that’s only going to get better in the next month or two.  Of course, that’s something wonderful to look forward to in the dead of winter.  We’ll just call this my own personal form of hibernating. Could I really get away with not leaving my house for an entire month? Hmmm….

I want to give you three ideas for having some quick wins that will help you feel really great about your genealogy this year.

Idea 1 – Finding Hidden Mitochondrial DNA

This happened to me just last night and distracted me so badly that I actually was late to wish everyone a Happy New Year.  Yes, seriously.  One of my friends told me this is the best excuse ever!

I was working on making a combined tree for the descendants of an ancestor who have tested and I suddenly noticed that one of the female autosomal matches descended from the female of the ancestral couple through all females – which means my match carries my ancestor’s mitochondrial DNA!

Woohooooooo – it’s a wonderful day.

Better yet, my match tested at Family Tree DNA AND had already taken the mitochondrial DNA test.

Within about 60 seconds of noticing her pattern of descent, I had the haplogroup of our common ancestor. That’s the BEST New Year’s gift EVER.  I couldn’t sleep last night.

So, know what I did instead of sleeping? I bet you can guess!

Yes indeed, I started searching through my matches at Family Tree DNA for other people descended from female ancestors whose mtDNA I don’t have!

So, my first challenge to you is to do the same.

Utilizing Family Finder, enter the surname you’re searching for into the search box in the upper right hand corner of your matches page.

That search will produce individuals who have that surname included in their list of ancestral surnames or who carry that surname themselves.

Your tree feeds the ancestral surname list with all of the surnames in your tree.  I understand this will be changing in the future to reflect only your direct line ancestral surnames.

Some people include locations with their surnames – so you may recognize your line that way. Click on your match’s surname list (at far right) to show their entire list of surnames in a popup box. Some lists are very long.  I selected the example below because it’s short.

Your common surnames are bolded and float to the top.  The name you are searching for will be blue, so it’s easy to see, especially in long lists of surnames. 

About half of my matches at Family Tree DNA have trees.  Click on the pedigree icon and then search for your surname of interest in your match’s tree.

Hey, there’s our common ancestral couple – William George Estes and Ollie Bolton!!!

Idea 2 – Finding Hidden Y DNA

Now that I’ve shown you how to find hidden mitochondrial DNA, finding hidden Y DNA is easy.  Right?

You know what to do.

I this case, you’ll be looking for a male candidate who carries the surname of the line you are seeking, which is very easy to spot on the match list.

Now, word of warning.

As bizarre as this sounds, not all men who carry that surname and match autosomally are from the same genetic surname line.

As I was working with building a community tree for my matches last night, I was excited to see that one of my cousins (whose kit I manage) matches a man with the Herrell surname.

I quickly clicked on the match’s tree to see which Herrell male the match descends from, only to discover that he didn’t descend from my Herrell line.

Whoa – you’re saying – hold on, because maybe my line is misidentified.  And I’d agree with you – except in this case, I have the Y DNA signature of both lines – because at one time I thought they were one and the same. You can view the Herrell Y DNA project here.  My family line is Harrold Line 7.

Sure enough, through the Family Finder match, I checked my Harrell match’s profile and his haplogroup is NOT the same as my Herrell haplogroup (I-P37.)

I could have easily been led astray by the same surname. I really don’t need to know any more about his Y DNA at this point, because the completely different haplogroup is enough to rule out a common paternal line.

Don’t let yourself get so excited that you forget to be a skeptical genealogist😊

My second challenge to you is to hunt for hidden Y DNA.

You can  increase your chances of finding your particular lineage by visiting the relevant Y DNA projects for your surname.

Click on Projects, then “Join a project,” then search for the DNA project that you’re interested in viewing and click on that link.

Within the project, look for oldest ancestors that are your ancestors, or potentially from a common location.  It’s someplace to start.

You can read more about how to construct a DNA pedigree chart in the article, “The DNA Pedigree Chart – Mining for Ancestors.”

Idea 3 – Pick A Puzzle Piece

Sometimes we get overwhelmed with the magnitude and size of the genealogy puzzle we’d like to solve. Then, we don’t solve anything.

This is exactly WHY I like the 52 Ancestor stories.  They make me focus on JUST ONE ancestor at a time.

So, for 2018, pick one genealogy puzzle you’d really like to solve. One person or one thing.  Not an entire line.

Write down your goal.

“I’d like to figure out whether John Doe was the son of William Doe or his son, Alexander Doe.”

Now admittedly, this is a tough one, because right off the bat, Y DNA isn’t going to help you unless you’re incredibly lucky and there is a mutation between Alexander Doe and his father, William.  If indeed that was the case, and you can prove it by the DNA of two of Alexander’s sons who carry the mutation, compared to the DNA of one of William’s other sons who does not, then you may be cooking with gas, presuming you can find a male Doe descended from John to test as well.

This is the type of thought process you’ll need to step through when considering all of the various options for how to prove, or disprove, a particular theory.

Make a list of the different kinds of evidence, both paper trail and genetic, that you could use to shed light on the problem. Your answer may not come from one piece of evidence alone, but a combination of several.

Evidence Available/Source Result
William’s will No, burned courthouse Verified
Alexander’s will No, burned courthouse Verified
Deeds with William as conveyor No, burned courthouse Verified
Family Bible Nope, no Bible
Deeds with Alexander as conveyor, naming John Possible, some deed books escaped fire Check through county, Family search does not list
Deeds with John as conveyor Yes, check to see if they indicate the source of John’s land John is listed in index, need to obtain original deeds from county
Y DNA of John’s line Yes, has been tested Matches DNA of William’s line as proven through William’s two brothers
Y DNA of Alexander Not tested (to the best of my knowledge), find descendant to see if they will test Search vendor DNA testing sites for male with this surname to see if they have/will Y DNA test
Closeness (in total cM and longest segment) of individuals autosomal matching through any of William’s descendants Mine both Ancestry and FTDNA for surname and ancestor matches This step may produce compelling or suggestive evidence, and it may not.  Make a McGuire chart of results.
Does John match any relatives of the wife of Alexander Doe? Search FTDNA and Ancestry for matches.  Triangulate to determine if match is valid and through that line. This is one of the best approaches to solve this type of problem when paper records aren’t available. Fingers crossed that Alexander and his wife and not related.

You can add pieces of evidence to your list as you think of them.

Making a list gives you something to work towards.

Your Turn!

Select one thing that you’d like to accomplish and either set about to do it, like mining for mitochondrial or Y DNA evidence, or put together a plan to gather evidence, both traditional and genetic.

In the comments, share what it is you’ll be searching for or working on.  You just never know if another subscriber may hold the answer you seek.

I can’t wait to hear what you’ll be doing this year!

Have a wonderful and productive New Year searching for those hidden ancestors!
