Glossary – DNA – Deoxyribonucleic Acid

What is DNA and why do I care?

Good questions. Let’s take a look at the answer in general, then why we use DNA for genealogy.

The Recipe for You

DNA, deoxyribonucleic acid, is the book of life for all organisms. In essence, it’s the recipe for you – and what makes you unique.

DNA is formed of strands that twist to form the familiar double helix pattern.

The two strands are joined together by one of 4 different nucleotides, one extending from each side to connect in the middle. The nucleotides are:

  • Cytosine – C
  • Guanine – G
  • Thymine – T
  • Adenine – A

The nucleotide names don’t really matter for genetic genealogy, but what does matter is that the sequence of these nucleotides when chained together is what encodes information on long structures called chromosomes. Each person carries 22 chromosomes, plus the 23rd chromosome pair which is gender specific.

Using DNA for Genetic Genealogy

There are four different kinds of DNA that genealogists use in different ways for obtaining ancestors’ information relevant to genetic genealogy. Thankfully, we have 4 different kinds of DNA available to us because of unique inheritance patterns for each kind of DNA – meaning we inherited different kinds of DNA from different ancestral paths. If one kind of DNA doesn’t work in a particular situation, chances are good that another type will.

Genetic genealogy makes use of 4 different types of DNA.

  • Y DNA – passed from males to male children, only (your father’s paternal line)
  • Mitochondrial DNA – passed from females to both genders of children, but only females pass it on (your mother’s matrilineal line)

Y and mitochondrial DNA inheritance paths are shown on a pedigree chart in the graphic below, with the blue boxes representing Y DNA and the red circles representing mitochondrial DNA inheritance.

In addition to Y and mitochondrial DNA, genetic genealogists also use two kinds of DNA that reflect inheritance from additional ancestral lines, in addition to the ones shown above – meaning the blue and red lines, in addition to the ancestral lines with no color.

  • Autosomal DNA – the 22 chromosomes that recombine during reproduction.
  • X Chromosome – always contributed by the mother, but only contributed by the father to female children – this is the 23rd chromosome pair which recombines with a unique inheritance pattern.  You can read more about that in the article, X Marks the Spot.

Receiving What Kind of DNA from Whom

While the Y and mitochondrial DNA have unique and very prescribed inheritance patterns as shown by the red arrows pointing to the blue Y chromosome below at far left, and the red mitochondrial circles at far right, the 22 autosomal chromosomes are contributed equally by each parent. In other words, for each chromosome, a child inherits half of each parent’s DNA. How the selection of which DNA is contributed to each child is unknown.

A child’s gender is determined by the parent’s contributions to the 23rd chromosome, not shown above. The following chart explains gender determination by the X and Y combinations of the 23rd chromosome.

Received from Mother Received from Father
Male child X Y
Female child X X

The Y chromosome is what makes males male.

No Y chromosome?  You’re a female.

However, this X chromosome inheritance pattern provides us with the ability to look at X matches for males and know immediately that they had to have come from his mother’s lineage – because males don’t inherit an X chromosome from their father.

Autosomal DNA and Genetic Genealogy

The 22 non-gender chromosomes recombine in each generation, with half of each chromosome being contributed by each parent, as shown in the illustrations above.

You can see that in the first generation, the child received one blue and one yellow, or one pink and one green, chromosome. In giving each child exactly half of their DNA, each parent contributes some amount of ancestral DNA from generations upstream, as you can see in the mother/father and son/daughter generations.

For example, each child receives, on average, 25% of each of their grandparent’s DNA – although they can receive somewhat more or less than 25%, depending on the random nature of recombination.

Therefore, genetic genealogy testing companies compare tester’s autosomal DNA with other testers and look for common segments contributed by common ancestors, resulting in autosomal matching.

When relatively large segments match between three or more relatives who are not immediate family, we can attribute that DNA to a common ancestor. Of course, the challenge, and the thrill, is to determine which common ancestor contributed that common DNA to our triangulated match group. It’s a great way to verify our research and to break down brick walls.

Let’s face it, you received ALL of your DNA from SOME combination of ancestors, and if you carry large enough pieces from any specific ancestor, we can, hopefully, identify the source of that DNA segment by looking at the genealogy of those we match on that segment.

It’s a great puzzle to unravel, and best of all, it’s the puzzle of you.

Using Spousal Surnames and DNA to Unravel Male Lines

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

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

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

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

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

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

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

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

Let’s see what we can discover.

Contact Matches and Ask for Help

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

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

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

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

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

Y DNA Genetic Distance

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

Please note that you can click to enlarge any graphic.

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

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

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

Check Autosomal DNA Tests

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

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

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

Check for Intermarriage

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

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

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

We’ll mark these in red to remind ourselves.

Check Advanced Matching

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

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

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

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

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

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

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

Search Utilizing the Wife’s Surname

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

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

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

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

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

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

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

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

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

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

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

But Wait – There’s a Happy Ending!

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Almost everything is on sale, including new kit orders, the Family Finder test, upgrades AND the Big Y.  This sale price of $395 is the best price I’ve ever seen on the Big Y.

If you’ve been waiting, now’s the time.  The sale starts August 1 between 9 and 10 AM Central time in the US and runs for the entire month of August.

I wasn’t kidding about family gatherings. I never, ever go to one of these events without at least kit in my purse. Seriously. You just never know.

If you don’t have a kit with you, you KNOW you’ll miss an opportunity!

I’ve learned to strike while the iron is hot, while the person is interested. If possible, I have them swab at the event so that kit doesn’t sit on their kitchen counter for the next year.

Yes, I know they aren’t supposed to eat for an hour before swabbing, BUT, I talk to them long enough for several minutes to pass and then have them swab, just like people do at conferences. So far, it has always worked out just fine.

The best thing is that seeing someone swab often garners interest from others as well, and you may just wind up having a DNA education session and swab party! What better to happen?

Quick Tip – How to Unjoin a Project at Family Tree DNA

Oops!  Did you accidentally join a project at Family Tree DNA in error, or just need to do some housekeeping?

Some folks think that only project administrators can remove people from projects, but people can unjoin themselves – and don’t have to wait on the administrator.

Removing yourself from a Family Tree DNA project is easy. Just click on the Projects tab, at the top right of your personal page, then on “Manage my projects.”

You will then see a list of the projects you have joined where you are currently a member. Click to enlarge the graphic below.

At the far right, you can click on “Leave Project” to unjoin yourself from the project.

The next screen you will see asks you to provide a reason for leaving.

Type something in the box, but please be nice – administrators are all volunteers – then click submit.

Understand that your reason is sent to the administrator, but they have no avenue to reply to you after you have left the project. So don’t expect to hear from them, because they can’t.  If you have a question for the admins or a discussion item, prior to leaving, just send them an e-mail.

Easy peasy!!

If you’re looking for how to select and join a project, you might enjoy How to Join a DNA Project.

Ethnicity and Physical Features are NOT Accurate Predictors of Parentage or Heritage

Let me say that again, ethnicity results are NOT an accurate predictor of heritage, or parentage. This is a great deal of confusion swirling around this topic. The fact that people are doubting parentage, or grandparentage, based on ethnicity results alone is alarming.

This week I receive this inquiry:

  • I recently found my suspected birth father but he says he’s probably not because he has 2 generations of Amerindian in him and my tests came back negative until I did the analysis at GedMatch and found it to show Amerindian in small traces.

And this:

  • I recently took an ethnicity test and it showed less Scandinavian than it should. My father’s grandfather was from Sweden. Since my Scandinavian is less than 25%, is my father really my father, and is his father really his father? Now I’m really confused and frightened.

Last week, I receive this inquiry:

  • My father and I both tested, but my ethnicity doesn’t all seem to be shared with him. Now I’m doubting whether he is really my father.

And this:

  • I received my ethnicity results, which showed no Native ancestry – but I know my ancestor was Native because she looks Indian in her photo.

And these are, by far, not the only inquiries in this vein. Some variation arrives almost every single day.

Be still my heart. Let me say this again

Why?

First, let’s talk about why, and then I’d like to share what I consider to be a perfect example with you.

Why is ethnicity alone not an accurate predictor of parentage or heritage?

  • The field of population genetics, which is the underlying science beneath ethnicity predictions, is in it’s infancy. This means that if you were to test with the various vendors who offer these tests, your results would come back with different readings, sometimes significantly different readings. And this is just for one person – you – not the combination of two people. You can see my results from various vendors in the article, Which Ethnicity Test is Best?
  • Ethnicity results from all vendors can only be considered estimates based on the people they are comparing your results to (reference panels) and their internal software algorithms.
  • Some vendors have more experience than others.
  • I have seen ethnicity results that reflect an ethnicity for a child that is not included in either parents’ ethnicity results, when the parents are unquestionably the biological parents of the child. Clearly, this can’t be accurate. I suggest reading the article, Ethnicity Testing, a Conundrum, to understand more about how ethnicity estimates are generated.
  • You can easily have an ethnicity not found in one parent, if you inherited that portion of your DNA from the other parent.
  • You may not have inherited a portion of DNA from a parent in which a particular ethnicity is found. Your parent may have it, and you may not have inherited that piece of DNA. For examples of how and why this works, please read the article, Ancestral DNA Percentages – How Much of Them is in You?
  • Ethnicity estimates are only considered to be predominantly accurate at the continent level, specifically, Asia, Europe, Africa, Native American and Jewish. Yes, I know that Native American and Jewish are not continents, but their DNA is different enough from the rest that the presence of Jewish or Native DNA is presumed to be, generally, accurate, unless they are very small amounts which could also be noise.
  • Unless you’ve tracked your ancestors back several generations through genealogy, you won’t have an accurate expectation of the percentages of ethnicity. For an article describing how to do this, please read, Concepts – Calculating Ethnicity Percentages and Concepts – Percentage of Ancestors’ DNA.
  • You do inherit exactly 50% of the DNA of your parents, but you do NOT necessarily inherit 50% of each ancestors’ DNA that your parents carried. For example, if your parent carries 6.25% of a particular ancestor’s DNA, which is equivalent to that of a great-grandparent, you may or may not inherit half, or 3.12%, of that ancestor’s DNA. You will inherit someplace between none and 6.25%. Please read the article, Generational Inheritance, for more information about how DNA is inherited in successive generations.
  • You may not inherit a portion of a specific ancestor’s DNA that reflects a particular ethnic admixture, or at least not that the reference panels used by various companies can identify as associated with that ethnicity today. For more on how companies determine ethnicity, please read Determining Ethnicity Percentages.
  • In the case of minority admixture, meaning when you carry a small amount of admixture from one ethnicity – it may or may not be noise. If it’s genuine, it may or may not be found by ethnicity tests.
  • The absence of an ethnicity in your ethnicity results is not evidence that the specific ethnicity was not present in your ancestor, especially back in time several generations.
  • The lack of an ethnicity in your results does NOT equate to the fact that an ancestor of that ethnicity is not your ancestor. In other words, you can have a Native American ancestor, back several generations, and not show Native American ancestry in your ethnicity results. Absence of evidence is not always evidence of absence.
  • In the case of admixture involving both Native and African, and especially in the US, your Native or African ancestor(s) may have been admixed themselves, so you don’t really know what to expect in terms of percentages.
  • How you look, known as your phenotype, may or may not reflect perceived or real heritage at the level you expect.

Can Ethnicity EVER Predict Parentage?

Ok, given the above, is there an example of where an ethnicity test MIGHT cause us to wonder at parentage?

At one time, I would have said yes, if you “look white” but your presumed parent was considered to be black, or vice versa. I’m using black and white here as examples because in the US, we have a lot of admixture and “white” and “black” are different enough from each other that one would expect to be able to visually tell the difference, especially in relatively recent generations.

However, that’s not always true. Remember the story about the black twin and white twin from the same parents?  Here’s the Snopes confirmation, along with photos.

My Friend, Rosario

Rosario has been most gracious in allowing me to share his story in advance of a book he is currently penning. His journey is particularly poignant, considering the discussion above.

Rosario studied at Harvard and then became…are you ready…an opera singer. Rosario was raised as an Italian man, specifically Sicilian. Fitting, as in Luciano Pavarotti. Those good Italian operatic genes.

Except…Rosario discovered that he isn’t Italian.

What he is, however, is a genealogist.

Rosario’s mother was taken from her parents and raised in foster care. She had a brother who was shipped off elsewhere, to other states, bouncing from one terrible situation to another until his untimely death. Separated as a child, she had little contact with her brother until they were adults, and then only on two occasions. Her brother and her parents were hushed-up secrets.

Rosario’s mother told him that her heritage was Sicilian, and Rosario became, culturally, a Sicilian man.

Interested in the challenge of his mother’s past, and as genealogists are inclined to do, Rosario started digging in like a dog after a bone. He wanted to share his proud Sicilian heritage with his children.

What he found would amaze him, shock him and leave him reeling – all at the same time.

The Truth Surfaces

First, Rosario found inconsistencies.

For example, he found three different birth certificates for his mother. No one has three birth certificates, but his mother did. One without a father’s race, one with the father’s race redacted and then a third one with all information present. The father was identified as “black” but given that Rosario was raised as Sicilian, an area in Europe where people are darker and could be identified as black, that was Rosario’s assumption. Made sense and might also explain the confusion and the three different birth certificate versions.

Maybe.

Rosario’s first real clue came when his DNA results were returned showing the following ethnicity mixture:

  • 18% Sub Saharan African
  • 2% Malagasy
  • 2% Native American
  • 78% European

Rosario didn’t exactly know what to do with these startling results. They couldn’t be true, because his father was white, his father’s parents were white and his mother’s parents were Sicilian.

Years would pass before additional inroads would be made, hindered by the legal system, his mother’s failing health, young children of his own and the lack of relatives. Rosario had no one to ask.

Eventually, Rosario would discover that his grandparents, his mother’s parents, one white and one black, were prosecuted for engaging in sexual activity with each other – in Vermont.

In fact, they were not allowed to marry due to their different races, and their children, Rosario’s mother and her brother, were removed from their parents when the parents were sent to prison for the crime of having sex with someone not of their race.

Rosario’s grandfather was black. And yes, he was sent to prison, for having sex with a white woman – in the northeast – not in the deep south. Rosario’s white grandmother was sent to prison as well, which is when Rosario’s mother was placed in a foster home and her “darker brother” was sent away – far away – to another state where he was caught up in a horrific maze of institutional abuse.

The photo above is from one of only two times as an adult that Rosario’s mother saw her brother.

Given what had already happened to Rosario’s mother, yanked from her parents and brother and placed in a foster home by the age of 9, it’s easy to see why she fabricated the story of her family being Sicilian. Dark-skinned Sicilian was much safer than “half black” in a place and time when people were sent to prison and children ripped from their families. Her brother would eventually commit suicide as the result of the abuses he suffered as a child – and not at the hands of his parents but as a result of horrible system in which he was systematically and repeatedly abused by adults who were supposedly “better” than his law-breaking parents.

For those of you who have never suffered the horrors of a family story in which your parent or grandparents were abused or mistreated, either by people they trusted or a system that was put in place to help them – good for you. But trust me, these revelations change the entire picture of who you think you are, your self-identity – and they will, guaranteed, rock your world to the point of physical nausea and literal nightmares.

The Photo

After adjusting for a bit, trying to absorb his new reality and attempting to come to grips with the abuses suffered by his grandfather, grandmother, mother and uncle, Rosario was beset by a new drive to get to know his until-then-missing grandparents.

Who were these people, as people? What were their lives like, before and after prison? Did they love each other? What did they look like? Were there any pictures?

Rosario looked high and low, and then finally, finally…through a hint planted in his mind in the middle of the night – Rosario woke up knowing the answer.

Earlier this year, Rosario was able to obtain his grandfather, Jerome Barber’s picture – a mugshot, the only photo he, or his mother, has ever seen of this man.

Jerome Barber’s Heritage

If Jerome Barber was entirely “black,” then his child, Rosario’s mother, would have been half black, or 50%, and Rosario would be 25% IF Rosario received exactly 25% of this grandfather’s DNA.

Looking at an expected DNA contribution of 25% African, given a black grandfather, compared to Rosario’s reported rate of 18% sub-Saharan African shows that expectation and reality can vary widely. In this case, there is a 7% difference with only one generation between Rosario and his “black” ancestor. It’s probable that Rosario’s 2% Malagasy and 2% Native also descend from this line based on testing of other family members including his mother and newly discovered relatives on his father’s side.

However, even with Rosario’s 18% sub-Saharan African and a black grandfather, until I told you, one would never look at Rosario and expect him to carry African heritage.

In photos of Rosario’s mother, you’d never guess that she is half black and half white, which is why she was “kept” and placed with a white foster family, while her brother, who was darker, was sent elsewhere. Unfortunately, Rosario’s uncle passed away before DNA testing was available.

So, in this case, Rosario’s phenotype, meaning how he looks, as compared to his genotype, his DNA contents, is deceiving and so is his mother’s.

Rosarios’s mother has DNA tested, and her results show only 28% sub-Saharan African where 50% would have been expected with a 100% black father.

Rosario’s expected amount of sub-Saharan African DNA would be 14% or half of his mother’s 28%, if you are calculating from his mother, but if you are calculating from a fully African grandfather, Rosario’s amount of African DNA would be expected to be 25%. Clearly, Jerome Barber wasn’t entirely black.

Expected percentages of DNA if Rosario’s grandfather was 100% African are shown below for each generation.

Expected Actual Difference
Grandfather 100 unknown unknown
Mother 50 28 -22%
Rosario 25 18 -7%
Rosario’s child 12.5 8 -4.5%

As you can see in the above calculations, based only on Rosario’s grandfather being entirely African, there is a significant difference, especially in his mother’s generation.

Looking at these DNA amounts differently, the next chart shows the expected amount of DNA calculated on the percentage of DNA the parent actually carries. Again, we begin with Rosario’s grandfather at 100%.

Expected Actual Difference
Grandfather 100 presumed unknown unknown
Mother 50 28 -22%
Rosario 14 18 +4%
Rosario’s child 7 8 +1%

Working backwards, given the amount of African DNA that Rosario’s mother has, 28%, Rosario’s grandfather may have only been about 56% African himself.

An awful irony.

Now that you know, you can look at Rosario and his grandfather’s photo together, and you can see the resemblance.

This same scenario works in reverse too. I cannot, tell you how many times people have sent me photographs with the idea that their ancestor “looks Native” but the DNA shows none or a small amount of Native admixture. In those cases, the DNA may show less than expected or no Native admixture because the DNA has washed out in the subsequent generations, the testing panels aren’t picking it up, or the ancestor wasn’t Native to begin with. It’s extremely easy to see a resemblance, especially if it’s something you are looking “for” or expect to see.

Identifying Parentage

If ethnicity isn’t a good predictor and is highly variable, then how does one identify a parent?

As I mentioned previously, every child inherits half of each parent’s DNA. Therefore, if any child and parent both take an autosomal DNA test from a vendor that provides matching and centimorgan (cM) amounts, in addition to ethnicity, you will know for sure if those two people are parent and child.

In the graphic below, I’m showing my mother’s DNA test which shows me as a match at Family Tree DNA.

You can see that the relationship is identified as parent/child, which means, genetically, the software can’t tell which one of us is the parent and which one of us is the child, but only a parent and child will share this amount of DNA.

By the way, the only reason I have my mother’s autosomal results to utilize, above, is because Family Tree DNA archives the DNA of their customers for 25 years, which allowed me to run the autosomal Family Finder test on her DNA years after her death.

You can also see in the chromosome browser, above, that I match my mother on the full length of every chromosome. The gray areas are not measured by the testing companies. Anyone who is not part of a parent/child relationship will not share all of all 22 chromosomes with someone who is not their parent or their child, except for identical twins. Said another way, if you are a parent or child, the entire portion of every chromosome 1-22 will match and be fully colored, as above.

Identical twins will match the full length of every chromosome too, but instead of the child matching 50% of the parent’s DNA, identical twins match exactly – 100% – not 50% – so the software vendors can tell the difference.

You can view the expected amount of DNA sharing for various relationships on this chart from the article, Concepts – Relationship Predictions.

Therefore, if you want to know whether or not someone is a parent, both parties must take an autosomal test at a vendor who provides matching between participants along with the amount of matching DNA and relationship predictions. Ironically, the test that provides the matching is the exact same test that provides ethnicity results – so if you tested at one of these vendors, you don’t have to take another test. You just have to look at matching results, assuming both people tested. Even if both parties aren’t available to test, such as the parent, if you can test a close relative of the purported parent, such as a sibling and still obtain probable confirmation, because close relatives tend to match within prescribed ranges.

Please, don’t just look at ethnicity results and begin questioning, or presuming.

The vendors who provide autosomal tests along with chromosome browsers are Family Tree DNA, used in the examples above, and 23andMe.

Ancestry also reports parent/child relationships and total matching DNA in centiMorgans (cMs), minus some amount of DNA removed by their Timber process, but does not provide a chromosome browser. MyHeritage reports relationships and cM amounts, but their cM matching amounts are problematic today and they do not provide a chromosome browser. Still, one should be able to discern a parent/child relationship from either Ancestry or MyHeritage.

You can read about the various vendor offerings in the article, Which DNA Test is Best?

Genetic Genealogy Tests are Not Legally Binding

Lastly, none of the genetic genealogy tests are legally binding relative to paternity, even though they can and do clearly inform of parentage.

These tests aren’t binding because the testers’ DNA samples lack “chain of custody,” meaning the DNA sample was not given in an environment where the identities of both testers can be legally proven. It would be very easy to return a negative paternity result by having your neighbor or buddy swab or spit for you. In other words, if you are looking for legal proof, to be used in legal proceedings, you need to consult with an attorney, follow their advice and utilize the methodologies, laboratories and procedures in your state or country to achieve your legal goals.

However, if what you are looking for is simply an answer, do NOT, NOT, NOT rely on any ethnicity results or appearances as hints.  Instead look at chromosome matching between the potential child and parent or close relative in the absence of a parent.

Summary

Rosario’s comments relative to ethnicity results and testing are very profound, especially given his recent experiences:

In your published articles, you astutely state the extremely variable nature of the companies’ platforms and methodologies. This begs the question, “is admixture variable or are the companies’ platforms?”

I think that this is the more appropriate question to ask.

People are taking their admixture results literally and that is a dangerous game to play. Families break up over this potent issue. We should tread lightly until we can demonstrate a more scientific conclusion than what is currently being offered.

I agree with Rosario, and would hazard an answer to his question as well.

How much DNA we inherit from any ancestor other than our parents is variable. Which DNA we inherit from any ancestor is variable.

The vendors test results, the reference populations and their internal algorithms are all variable.

Therefore, everything about ethnicity testing is at least somewhat variable – and is exactly why ethnicity testing should NEVER be interpreted as an indicator of parentage.

Chromosome matching is not variable relative to a biological parent/child relationship. Children always inherit half of the autosomal DNA of each parent on chromosomes 1-22.

Correction note:  Jerome’s surname corrected to read Barber.  Jackson was Jerome’s mother’s surname.

Which Ethnicity Test is Best?

While this question is very straightforward, the answer is not.

I have tested with or uploaded my DNA file to the following vendors to obtain ethnicity results:

The links above provide product reviews of recently released or updated results.

Guess what? None of the vendors’ results are the same. Some aren’t even close to each other, let alone to my known and proven genealogy.

In the article, Concepts – Calculating Ethnicity Percentages, I explained how to calculate your expected ethnicity percentages from your genealogy. As each vendor has introduced ethnicity results, or updated previous results, I’ve added to a cumulative chart.

It bears repeating before we look at that chart that ethnicity testing is relatively accurate on a continental level, meaning:

  • Africa
  • Europe
  • Asia
  • Native American
  • Jewish

Intra-continent or sub-continent, meaning within continents, it’s extremely difficult to tease out differences between countries, like France, Germany and Switzerland. Looking at the size of these regions, and the movement of populations, we can certainly understand why. In many ways, it’s like trying to discern the difference between Indiana and Illinois.

What Does “Best” Mean?

While the question of which test is best seems like it would be easy to answer, it isn’t.

“Best” is a subjective term, and often, people interpret best to mean that the test reflects a portion of what they think they know about their ethnicity. Without a rather robust and proven tree, some testers have little subjective data on which to base their perceptions.  In fact, many people, encouraged by advertising, take these tests with the hope that the test will in fact provide them with the answer to the question, “Who am I?” or to confirm a specific ancestor or ancestral heritage rumor.

For example, people often test to find their Native American ancestry and are disappointed when the results don’t reveal Native ancestry. This can be because:

  • There is no Native ancestor.
  • The Native ancestor thought to be 100% was already highly admixed.
  • The Native ancestor is too far back in the tester’s tree and the ancestor’s DNA “washed out” in subsequent generations.
  • The testing company failed to pick up what might be arguably a trace amount.

Genealogy Compared to All Vendors’ Results

In some cases, discrepancies arise due to how the different companies group their results and what the groupings mean, as you can see in the table below comparing all vendors’ results to my known genealogy.

In the table below, I’ve highlighted in yellow the “best” company result by region, as compared to my known genealogy shown in the column titled “Genealogy %”.

British Isles – The British Isles is fairly easy to define, because they are islands, and the results for each vendor, other than The Genographic Project, are easy to group into that category as well. Family Tree DNA comes the closest to my known genealogy in this category, so would be the “best” in this category. However, every region, shown in pink, does not have the same “best” vendor.

Scandinavian – I have no actual Scandinavian heritage in my genealogy, but I’m betting I have a number of Vikings, or that my German/Dutch is closely related to the Scandinavians. So while LivingDNA is the lowest, meaning the closest to my zero, it’s very difficult to discern the “true” amount of Scandinavian heritage admixed into the other populations. It’s also possible that Scandinavian is not reflecting (entirely) the Vikings, but Dutch and German as a result of migrations of entire peoples. My German and Dutch ancestry cumulatively adds to 39%.

Eastern European – I don’t have any known Eastern European, but some of my German might fall into that category, historically. I simply don’t know, so I’m not ranking that group.

Northwestern Europe – For the balance of Northwestern Europe, 23andMe comes the closest with 43% of my 45.24% from my known genealogy.

Mediterranean and Southern European – For the Mediterranean, Greece, Italy and Southern Europe, I have no known genealogy there, and not even anyplace close, so I’m counting as accurate all three vendors who reported zero, being Living DNA, Family Tree DNA and MyHeritage.

Unknown – The next grouping is my unknown percentage. It’s very difficult to ascribe a right or wrong to this grouping, so I’ve put vendor results here that might fall into that unknown group. In my case, I suspect that some of the unknown is actually Native on my father’s side. I haven’t assigned accuracy in this section. It’s more of a catch all, for now.

Native and Asian – The next section is Native and Asian, which can in some circumstances can be attributed to Native ancestry. In this case, I know of about 1% proven Native heritage, as the Native on my mother’s line is proven utilizing both Y and mitochondrial DNA tests on descendants. I suspect there is more Native to be revealed, both on her side and because I can’t positively attribute some of my father’s lineage that is mixed race and reported to be Native, but is as yet unproven. By proof, I mean either Y DNA, mitochondrial DNA or concrete documentation.

I have counted any vendor who found a region above zero and smaller than my unknown percentage of 3.9% as accurate, those vendors being Family Tree DNA, Ancestry, 23andMe and MyHeritage.

Southwest Asia – I have no heritage from Southwest Asia, which typically means the Indian subcontinent. National Geographic reports this region, but their categories are much broader than the other companies, as reflected by the grey bands utilized to attempt to summarize the other vendor’s data in a way that can be compared to the Genographic Project information. While I’m pleased to contribute to the National Geographic Society through the Genographic Project, the results are the least connected to my known genealogy, although their results may represent deeper migratory ancestry.

Summary

As you can see, the best vendor is almost impossible to pinpoint and every person that tests at multiple vendors will likely have a different opinion of what is “best” and the reasons why. In some ways, best depends on what you are looking for and how much genealogy work you’ve already invested to be able to reliably evaluate the different vendor results. In my case, the best vendor, judged by the highest total percentage of “most accurate” categories would be Family Tree DNA.

While DNA testing for ethnicity really doesn’t provide the level of specificity that people hope to gain, testers can generally get a good view of their ancestry at the continental level. Vendors also provide updates as the reference groups and technology improves.  This is a learning experience for all involved!

I hope that seeing the differences between the various vendors will encourage people to test at multiple vendors, or transfer their results to additional vendors to gain “a second set of eyes” about their ethnicity. Several transfers are free. You can read about which vendors accept results from other vendors, in the article, Autosomal DNA Transfers – Which Companies Accept Which Tests?

I also hope that ethnicity results encourage people to pursue their genealogy to find their ancestors. Ethnicity results are fun, but they aren’t gospel, and shouldn’t be interpreted as “the answer.” Just enjoy your results and allow them to peak your curiosity to discover who your ancestors really were through genealogy research! There are bound to be some fun surprises just waiting to be discovered.

If you are interested in why your results may vary from what you expected, please read “Ethnicity Testing – A Conundrum.”

If you’re interested in taking a DNA test, you might want to read “Which DNA Test is Best?” which discusses and compares what you need to know about each vendor and the different tests available in the genetic genealogy market today.

Hugs in the Churchyard – Thanks to Y DNA

Isn’t this just a wonderful picture? Even though the picture is of two very excited female cousins, it’s all because of Y DNA. Don’t tell anyone, but I think we might have jumped up and down a few times too (wink), with very good reason!

This exuberant photo is my cousin, Mary and me, in the cemetery of the church in Downham, Lancashire, England where our ancestor, Thomas Speake was baptized in 1634. How we got here is truly a genetic journey, and we couldn’t have done it without our Speak male cousins who were all too willing to help by Y DNA testing!

Mary and I share ancestor, Nicholas Speaks, who was born in 1782 in Charles County, Maryland and migrated as a child with his father to Washington County, Virginia where he married Sarah Faires. The young couple homesteaded in Lee County, Virginia, establishing the first Methodist Church in the area about 1822.

When Cousin Mary and I began our genealogy journey, along with a few other cousins, years ago, we didn’t have any information prior to Lee County. Where did Nicholas come from and who were his parents?

Over the years, our line was traced back to Maryland in the 1600s to immigrant Thomas Speak. However, we were truly stuck in Maryland, with absolutely no idea where Thomas originated in the UK. It was like looking for a needle in a haystack.

Several Speak men Y DNA tested when DNA testing became available, and then the wait began. A few years later, they matched a man who lived in New Zealand. The Speak cousin from New Zealand knew a lot more about his ancestors in England than we did since they migrated to New Zealand in the 1800s, not the 1600s like our Thomas Speak.

Our newly discovered cousin from down-under pointed us to the little town of Gisburn, where his Speak ancestor was born and baptized. Our Thomas’s baptismal record wasn’t in Gisburn, but working in a circle in surrounding communities turned up Thomas’s baptismal record in 1634 in the tiny village of Downham, just 4 miles distant.

The baptismal record further told us that Thomas was from an even smaller village, if that’s even possible.  Twiston is more of a farming hamlet (shown below), a mile or so away from Downham down a tiny road so twisty that anything larger than a passenger vehicle can’t navigate the road.  Let’s just say I have personal knowledge of this issue:)

Two years later, after our amazing DNA discovery, followed by confirming record discoveries, about 20 descendants of the Speak family of Gisburn and Downham, including our New Zealand cousin, arranged a tour back to our homeland. We met in London, having rented a bus and driver, and off we went to Lancashire on a journey back in time.

This amazing adventure truly was the trip of a lifetime, a dream come true, with cousins near and dear to my heart, finding and honoring our common ancestral homeland.

All, thanks to Y DNA. Y DNA isn’t always a sprint, although sometimes you have an important immediate match. Y DNA is sometimes more of a wait and be patient proposition, as the DNA results are constantly fishing for you – but it’s so, so, worth the wait.

I hope that you too get to hug your cousin in the cemetery where your ancestors are buried on a journey someplace you could never have imagined. But you’ll never get to hug in that cemetery if you don’t start the journey by testing. I couldn’t test myself, being a female, but I surely could test my cousins – and I have – lots of them!

All of genetic genealogy is a collaborative journey and you never know which new tester will make that fateful difference!

With Father’s Day on the horizon, and a sale at Family Tree DNA, there’s no better time to test your male lines that haven’t yet tested. You truly never know what wonderful adventure or new cousin is waiting. Give the gift of discovery.
