The Shoes

During my recent overseas adventure, I visited both Nuremburg, Germany and Budapest, Hungary, among other locations. These two cities, especially in combination, were intensely moving.

My husband’s family immigrated from the Austrian-Hungarian empire in the early 1900s. The area had been ravaged by multiple wars followed by desperate economic strife and geographic displacement of the residents – not to mention changing national borders. However, that history, as difficult as it was, was overshadowed a few years later by the horrible history of the Nazi era. It’s a good thing his family left when they did, because they would likely have not escaped later. Many did not.

He probably would not have been on this earth today.

Nuremberg

It’s sad that a city lives in infamy for its worst moments. Thankfully, today, rather than attempt to whitewash the past, the Nuremburg citizens realize that they can use the past as a source of education about what they refer to as “our dark time in history.”

Wikipedia contains a short description about Nuremburg history during this timeframe:

Nuremberg held great significance during the Nazi Germany era. Because of the city’s relevance to the Holy Roman Empire and its position in the centre of Germany, the Nazi Party chose the city to be the site of huge Nazi Party conventions — the Nuremberg rallies. The rallies were held 1927, 1929 and annually 1933–1938 in Nuremberg. After Adolf Hitler’s rise to power in 1933 the Nuremberg rallies became huge Nazi propaganda events, a centre of Nazi ideals. The 1934 rally was filmed by Leni Riefenstahl, and made into a propaganda film called Triumph des Willens (Triumph of the Will). At the 1935 rally, Hitler specifically ordered the Reichstag to convene at Nuremberg to pass the anti-Semitic Nuremberg Laws which revoked German citizenship for all Jews and other non-Aryans. A number of premises were constructed solely for these assemblies, some of which were not finished. Today many examples of Nazi architecture can still be seen in the city.

We all know what happened next.

As a member of the human race, one my biggest fears is that discrimination, racism and misogyny on this level will once again manifest itself.

Visiting Nuremburg, seeing those places for myself was at the same time sobering and spine-chilling. The cavernous locations of Hitler’s rallies, large enough to encompass a full city block and drive multiple busses around inside the arena. The arena below was filled with people and you’re only seeing about one fourth of the size.

The now-silent cheers of Hitler’s legions of Nazi supporters haunt this place, those who would advance his agenda and follow his lead to condemn millions of Jews and other “undesireables” to death – simply because of how they looked or their religion. Fear-incited genocide propagated by a charismatic leader sewing fear and mass hysteria.

Hitler is known for systematically killing Jews, but they weren’t his only targets. Additionally, he singled out LGBTQ individuals, the physically and mentally disabled, Roma gypsies, Poles and other Slavic peoples, Jehova’s Witnesses, blacks, mixed race “mulattos” and members of political opposition groups. According to the Virtual Jewish Library, Hitler killed more than 11 million people in total – 6 million Jews and 5 million others.

Eleven. Million. People.

Think about that for a minute.

New York City’s’s estimated population in 2016 was only 8.5 million. Eleven million is the size of New York City and Chicago, combined. The equivalent populations of both of those cities, today, died at Hitler’s hands.

In 1986, the Hands Across America benefit united 6.5 million people in a human chain from literally sea to sea. If every person stood 4 feet apart, 6.5 million people would have covered the contiguous 48 states. So, 11 million people standing shoulder to shoulder would stretch about the same distance – or standing at 4 feet – across America – twice.

Eleven million is an astounding number. I have to ask myself, how did Hitler, or anyone, manage to convince so many Europeans that the horrific murder of 11 million people was not only alright, but justified, AND convinced them to assist and abet this mass murderer by either willfully participating or turning a blind eye?

And in case you’re feeling particularly self-righteous as an American, our collective hands were not without bloodstain. In 1939, a ship, the MS St. Louis, carrying 937 Jewish refugees sailed from Hamburg first to Cuba, where only 29 individuals were allowed to disembark, and then to Florida and Canada seeking asylum, where the ship was not allowed to dock. The ship’s captain subsequently attempted to find safe haven for his passengers in European ports, having no place left to go, but 254 of those turned away by Cuba, the US and Canada were subsequently killed in the Holocaust after the ship and her 907 remaining passengers (one died in route) were forced to return.

Turning a blind eye to fellow humans is aiding and abetting. Failing to condemn horrific behavior is aiding and abetting.

The poem, “First They Came,” was written by German Lutheran pastor Martin Niemöller (1892–1984), a former Nazi supporter who survived a Nazi prison. His poem addresses the cowardice of German intellectuals following the Nazis‘ rise to power and subsequent purging of their chosen targets.

First they came for the Socialists, and I did not speak out—
Because I was not a Socialist.

Then they came for the Trade Unionists, and I did not speak out—
Because I was not a Trade Unionist.

Then they came for the Jews, and I did not speak out—
Because I was not a Jew.

Then they came for me—and there was no one left to speak for me.

And then, there are the heroes, like Sir Nicholas Winton who saved 669 Jewish children from the Nazi death camps. For a tear jerker, watch Nicholas meet those children decades later as adults. Just ordinary people – look at them. Get the Kleenex, because you will not get through this with dry eyes, I guarantee. You’re in good company, because neither could Nicholas.

Speaking about Nicholas, the Dalai Lama said,

“We must carry his spirit generation to generation.”

To forget history, or to ignore it, is to repeat it.

Budapest

A few days after Nuremberg, we arrived in the lovely city of Budapest, an incredible combination of the old medieval city shown by the spires in the distance combined with a cosmopolitan modern city that was sporting the international diving championships (the blue scaffold) along the Danube while we were visiting.

Having injured my knee at the beginning of the trip, I was skipping out on many of the walking tours, because I simply couldn’t handle that many hours on my feet.

However, as we returned to the ship after a bus tour in the morning, I noticed the shoes.

The tour guide, busy talking about the diving championships, didn’t say anything about the shoes, but I knew immediately what they were when I saw them.

In 1944 and 1945, 3,500 people, 800 of them Jews, were killed in Budapest by the Hungarian fascist party by being lined up on the banks of the Danube River, ordered to remove their shoes, then shot at the edge of the water so that their bodies fell into the river and were whisked away – like so much human rubbish.

By Tamas Szabo at English Wikipedia, CC BY-SA 3.0, https://commons.wikimedia.org/w/index.php?curid=2054459

The Shoes on the Danube Bank memorial was created with 60 period-appropriate shoes cast of iron and affixed along the riverbank for 40 meters. If all 3,500 pairs of feet had been represented, shoes side by side, the memorial would have stretched for the length of more than a mile.

I walked alone along the riverbank on a sweltering summer afternoon in the middle of a heat wave named Lucifer for its punishing intensity, the sun searing and miserable. This memorial is not something you should be comfortable seeing. Discomfort, as well as pain, was welcome and appropriate – and nothing compared to what those people, and their families, endured.

Can you imagine the fear, the horror of seeing your family members, your parents, your siblings, your children, murdered – and knowing you were marching to your sure and certain deaths? The only unknown was how much you would suffer, and for how long.

And it wasn’t just Jews, but anyone who had the audacity to speak up for what was right, which was politically very unpopular – unpopular to the point of death. Death, intimidation, torture, murder, subjugation and annihilation was the Nazi way.

As my gaze was fixed on the empty shoes representing this waste of humanity, I was struck by how much potential was washed away, not just with these 3,500, but with the 11 million in total. How many never contributed to the good of humanity, but would have? Did the person destined to save us from cancer die? What is the unknown cost to us all?

After all, we all bleed blood – the great equalizer, along with birth and death.

What did we do to ourselves, not only with the wasted lives and unrealized potential of those who died, but with the horrid gash we inflicted upon our own souls?

I didn’t want to look, yet I couldn’t look away. I could see their bodies falling into the water, gasping for breath, hopefully, mercifully, dead by the time they hit the water. I pray their deaths were at least swift.

None of us can afford to look away. We must, in the name of humanity, prevent this from ever happening again.

I spent the afternoon alone, in contemplative silence, although surrounded by other walkers.  I sat behind and among the shoes, reflecting not only upon the deaths of so many innocents, but the challenges we face today in a worldwide atmosphere where rampant hatred and discrimination based on the slight differences of human form and our different religious choices seems to be making a virulent comeback.

I felt shame that we, in a global sense, and as individuals, let this happen. That we failed so many.  We must never let it happen again. We must be wiser now.

More the Same Than Different

The DNA of all humans is 99.9% the same, with very few differences. While we depend upon those differences for genetic genealogy, for the most part, we match every other living human.

Remember how many people whose DNA you match that you didn’t expect and don’t know, but you’re somehow related to?

Think about how many of those 11 million people that died you were related to.

Think you’re not?

I have over 30,000 matches among Ancestry’s data base of 5 million – and even if you generously subtract 25% with the assumption they are false positives, that means that I’m related to about 22,000 of 5 million people I don’t know. That means that I would probably have been related to many of the people who died in the Holocaust, maybe between 45,000 and 60,000 of them. That brings it a lot closer to home.

I’m not Jewish, and still, I’m sure that some of my relatives died.  Assuredly, my husband’s did.

The Future

The Holocaust is no longer simply a lesson in history that happened three quarters of a century ago, it’s a dire warning about what is happening today as well.

Because.

Today we have Charlottesville. The re-emergence of the horrific.

Today we hear, on our own soil, horrible racial and anti-Semitic epithets, espousing hatred and bigotry. As far as I’m concerned, it doesn’t matter who leads this country or which party is in power, wrong is wrong.

Hatred is hatred.

Seeds of discrimination and hatred sew discrimination and hatred that leads to violence which is the exact scenario that led to Hitler’s massive genocide.

Refusal to condemn and combat hatred and discrimination on an individual level, as well as a national level, simply begets more of the same. We’ve already seen where that leads. Do we have to go there again?

The recorded history of the world, to date, has been punctuated repeatedly by horrific wars (30 Years War, Revolutionary War, Civil War, WWI and II with its atomic bomb, to name a few), slavery (African, Native American, Moorish and English, as a beginning) on every continent except Antarctica, genocide (Native American, Jewish, South American, African, as examples) and the murder and/or displacement of millions of people due to their religious differences (Catholics, Protestants, Muslims, aboriginals, perceived witches and the Crusades for starters).

Not one of us lives today whose ancestors weren’t affected by these factors.

Not. One.

Probably every single one of us had ancestors who were enslaved, killed or displaced – one way or another suffering at the hands of other humans within a genealogical timeframe. On this continent – Acadians, Native Americans and Africans come quickly to mind. In the UK, Catholics and the Irish.  The list goes on – all at the hands of a ruling class that either lost or never had a moral compass.

Are we condemned to repeat that past?

Not on my watch.

Never again.

Not if I can do anything about it.

Not as long as there is a breath in my body.

In the words of Nobel Peace Prize recipient, Nelson Mandela:

No one is born hating another person because of the color of his skin or his background or his religion. People must learn to hate, and if they can learn to hate, they can be taught to love. For love comes more naturally to the human heart than its opposite.

I hope that our DNA connections show us how much we have in common with others and serve to bring us together as the human race, celebrating our diverse roots and our humanity. Remember, the Momondo DNA Journey where 67 people were tested to celebrate diversity around the world and travel to where their ancestors were from? Take a look, here for one example. It’s an amazing story, really, that challenges pre-conceived notions and biases.

In one participant’s words:

“There would be no such thing as, like, extremism in the world, if people knew their heritage like that.”

We’re all cousins.

Remember The Shoes…

…and pray, pray, that no one ever has to stand in them again.

This time, it could be you.

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.

Ancestral DNA Percentages – How Much of Them is in You?

One of the most common questions I receive, especially in light of the interest in ethnicity testing, is how much of an ancestor’s DNA someone “should” share.

The chart above shows how much of a particular generation of ancestors’ DNA you would inherit if each generation between you and that ancestor inherited exactly 50% of that ancestor’s DNA from their parent. This means, on the average, you will carry less than 1% of each of your 5 times great-grandparents DNA, shown in generation 7, in total. You’ll carry about 1.56% of each of your 6 times great-grandparents, and so forth.

As you can see, if you’re looking for a Native American ancestor, for example, who is 7 generations back in your tree, if you carry the average amount of DNA from that ancestor, it will be less than 1% which will be under the noise threshold for detection – and that’s assuming they were 100% Native at that time.

Everyone inherits 50% of their DNA from their parents, but not everyone inherits half of each of their ancestors’ DNA from a parent. Sometimes, the child will inherit all of a segment of DNA from an ancestor, and in other cases, the child will inherit none. In some cases, they will inherit half or a portion of the DNA from an ancestor. In reality, the DNA segments are very seldom divided exactly in half, but all we can deal with are averages when discussing how much DNA you “should” receive from an ancestor, based on where they are in your tree.

The generational relationship chart above represents the average that you will inherit from each of those ancestors. Of course, few people are actually average, and you may not be either. In other words, your ancestor’s DNA may not be detectible at 5, 6 or 7 generations, because it was lost in generations between them and you, while another ancestor’s DNA is still present in detectable amounts at 8 or 9 generations.

How Does Inheritance of Ancestral Segments Actually Work?

For you to inherit a particular segment from one GGGGG-grandparent, the inheritance might look something like this. “You” are at the bottom of the tree. You can click on any graphic to enlarge.

In the above example, you inherited one tenth of the segment from your GGGGG-grandparent which was one third of the DNA that your parent carried in that segment from that ancestor.

A second example is every bit as likely, shown below.

In this second scenario, you inherited nothing of that segment from your GGGGG-grandparent.

A third scenario is also a possibility.

In this third scenario, you inherited all of the DNA from that ancestor as your parent.

Now, think of these three scenarios as three different siblings inheriting from the same parent, and you’ll understand why siblings carry different amounts of DNA from their ancestors.

Of course, the child can only inherit what the parent has inherited from that ancestor, and if that particular segment was gone in the parent’s generation, or generations before the parent, the child certainly can’t inherit the segment. There is no such thing as “skipping generations.”

In this fourth scenario, the parent didn’t receive any of the segment from the GGGGG-grandparent, but maybe their brother or sister did, which is why you want to test aunts and uncles. Testing everyone in your family available from the oldest generation is absolutely critical.

This, of course, is exactly why we test as many relatives as we can. Everyone inherits different amounts of segments of DNA from our common ancestors. This is also why we map our matching segments to those ancestors by triangulating with cousins – to identify which pieces of our DNA came from which ancestor.

Seeing examples of how inheritance works helps us understand that there is no “one answer” to the question we want to know about each ancestor – “How much of you is in me?” The answer is, “it depends” and the actual amount would be different for every ancestor except your parents, where the answer is always 50%.

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.

MyHeritage Ethnicity Results

I originally wrote about MyHeritage in February 2017, reflecting matching issues and a broken promise regarding providing ethnicity estimates to people who uploaded their raw DNA file from another vendor. I’m glad to say MyHeritage changed their minds about providing ethnicity results and, today, has honored their original commitment and provided free ethnicity results to uploaders. I feel much better about the DNA aspect of MyHeritage given this decision although their challenges with matching remain.

MyHeritage has also provided updated ethnicity results to people who tested directly at MyHeritage.

In an e-mail received today from Aaron Godfrey, their Director of Marketing, he says:

I wanted to let you know that we’ve just launched MyHeritage’s new and improved Ethnicity Estimate. The new analysis, developed by the company’s science team, provides MyHeritage DNA customers with a percentage-based estimate of their ethnic origins covering 42 ethnic regions, many unique to MyHeritage.

In addition, the new Ethnicity Estimate will be provided for free to users who have already uploaded their DNA data to MyHeritage from other services, or who will upload it in the coming months. Users who upload their DNA data to MyHeritage, already enjoy free DNA Matching, and now they will benefit from the new ethnicity analysis too.

Our Ethnicity Estimate is delivered to users through a captivating “reveal” experience featuring animation and, as of this week, original music composed by MyHeritage. Each of the 42 ethnicities has a distinctive tune, based on the region’s cultural elements; all tunes seamlessly connect to each other. You can view an example here:  https://vimeo.com/218348730/51174e0b49

An excerpt from their press release is provided below:

TEL AVIV, Israel & LEHI, Utah, May 30, 2017 – MyHeritage, the leading global destination for family history and DNA testing, and the makers of the successful MyHeritage DNA product, today announced the launch of its new and improved Ethnicity Estimate. The new analysis, developed by the company’s science team, provides MyHeritage DNA customers with a percentage-based estimate of their ethnic origins covering 42 ethnic regions, many available only on MyHeritage, representing the most comprehensive report of its type available on the market. This fascinating report gives users a much better understanding of who they are and where their ancestors came from. The Ethnicity Estimate is presented in an original and engaging format, making it not only interesting but also fun to watch and share.

MyHeritage is unique among the main industry players in allowing users who have tested their DNA already with another service to upload – for free – their data to MyHeritage. Those users receive DNA Matches for free, for finding relatives based on shared DNA. Beginning this week, users who have already uploaded their DNA data to MyHeritage, or who will upload it in the coming months, will receive – for free – the new Ethnicity Estimate. This benefit is not offered by any other major DNA company.

Development of the new Ethnicity Estimate raises the number of ethnic regions covered by MyHeritage DNA from 36 to 42. It was made possible thanks to MyHeritage’s Founder Populations project — one of the largest of its kind ever conducted. For this unique project, more than 5,000 participants were handpicked by MyHeritage from its 90 million strong user base, by virtue of their family trees exemplifying consistent ancestry from the same region or ethnicity for many generations All project participants received complimentary DNA tests and allowed MyHeritage’s science team to develop breakthrough ethnicity models based on the generated data. Thanks to this analysis, MyHeritage DNA has become the only mass-market percentage-based DNA test that reveals ethnicities such as Balkan; Baltic; Eskimo & Inuit; Japanese; Kenyan; Sierra Leonean; Somali; four major Jewish groups – Ethiopian, Yemenite, Sephardic from North Africa and Mizrahi from Iran and Iraq; Indigenous Amazonian; Papuan and many others. In some cases, competing products can identify and report an aggregated region (e.g., Italian & Greek), whereas MyHeritage has better resolution and identifies Greek, Italian and Sardinian ethnicities separately.

MyHeritage’s new Ethnicity Estimate is delivered to users via a captivating “reveal” experience (view example). It features animation and, as of this week, also original music composed by MyHeritage. Each of the 42 ethnicities has a distinctive tune, based on the region’s cultural elements; all tunes seamlessly connect to each other. This makes the report fun to watch and share over social media.

Dr. Yaniv Erlich, Chief Science Officer at MyHeritage, said, “For MyHeritage’s science team, this major update of our Ethnicity Estimate is only an appetizer. There are excellent installments on the way, and users can prepare for a feast! We have detailed plans to increase accuracy, extend our Founder Populations project further, and improve the resolution for ethnicities of great interest to our users from highly diverse origins. Our goal is to use science to further the public good, and to bring the best innovations of our science team to the public.”

If you tested earlier, your results have been updated and your “reveal intro” with music added. Check it out.

If you uploaded previously, you had no ethnicity results, but now you do.

Regions Reported

From my results, the regions that MyHeritage supports, meaning the regions they report, are as follows:

The regions above correlate with the regions shown on the map at the beginning of this article.

My Ethnicity Results

I filmed my own reveal to share with you, but viewing their Vimeo clip linked above is much better quality. I particularly enjoyed the music compositions from the locations where my ethnicity is reported.

As with other vendors who offer ethnicity services, I have compared the MyHeritage ethnicity results with my known genealogy, and then as compared to other vendors.

Let’s look at my results.

The first thing I noticed is that the British Isles is broken into two components, English and then Irish/Scottish/Welsh. Of course, looking at the map, they do overlap almost entirely.

The second thing I noticed is that, according to MyHeritage, I’m indigenous Amazonian.

My reaction to that? You’ve got to be kidding.

Now, the good news is that they did detect my Native American, which, by the way, is either from my mother’s side out of Nova Scotia (Acadian), which is proven in several ancestral lines via mtDNA and Y DNA testing, or from my father’s line from near the Virginia/North Carolina border, or both.

The bad news is that they have badly mislabeled my Native finding. What this really means is that their reference population is from the Amazon. Of course, all Native people spring from a few hearty settlers that crossed Beringia from Russia into what is now Canada someplace between (roughly) 12,000 and 15,000 years ago, so it’s not surprising that I do match the people from the Amazon at some level. However, that does not mean my DNA is indigenous Amazonian, or that my ancestors were ever anyplace NEAR the Amazon or even South America.

Ethnicity vs Genealogy Comparison

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 the cumulative chart.

Let’s see how MyHeritage stacks up against my known genealogy.

MyHeritage uses groupings slightly differently than I grouped my genealogy, so in the British Isles region, I’ve used yellow and green to show like groupings of my genealogy as compared to the MyHeritage results. As you can see, the 44.4% England attributed by MyHeritage is very close to the 43.68% found in my genealogy. The Irish/Scottish/Welsh, not quite so close.

MyHeritage Compared to Other Vendors

Adding MyHeritage to the table with the other vendors’ current results, we find the following:

Please note that you can click to enlarge.

The easiest way to compare apples to apples is to look at the pink region totals. The various vendors separate out the geographic regions differently, so it’s difficult to compare one directly to another.

Uploading or Testing at MyHeritage

You can still upload your data file if you tested with another company, for free, and obtain your matches and your ethnicity. You can add a tree up to 250 people for free, but beyond that, you must subscribe. I have had reports of people receiving phone calls from MyHeritage encouraging them to subscribe after utilizing the free tree, although I cannot confirm this personally as I subscribed when I decided to utilize their trees.

Although you can include a tree, MyHeritage does not provide tree matching for people whose DNA matches, showing common surnames or a common ancestor if one is listed.

As always with any vendor, read the Terms and Conditions, Privacy Policy and any other linked documents when considering either a purchase or uploading your DNA results from another testing company. The MyHeritage Privacy Policy is here and Terms and Conditions are here.

You can upload your autosomal DNA results for free here.

LivingDNA Product Review

Living DNA entered the landscape for ethnicity testing in the summer/fall of 2016. Hands down, they win the contest for “cool logo.”

Ordering and Waiting

I ordered my test, and the results were frustratingly slow in arriving – more than 3 months after submission. Their website currently says “within 10-12 weeks our results will be ready to explore.” Speedy is not their middle name. At first I thought the delivery time of 12 weeks was a startup snafu, but apparently it’s their standard delivery window.

Sometimes vendors offer free tests with the hope of a good review. I typically order tests like any other customer from a vendor, because it’s not a fair review if the vendor knows they are testing someone who will likely review their product. In other words, I don’t want special treatment. However, in this case, I did complain to the Marketing Director and received my results shortly thereafter. I don’t know how long those results would have taken otherwise.

Price

LivingDNA is a British company, registered in England and Wales. Their price in US dollars is normally $159 with an additional $9.95 for standard delivery (5-7 working days) or $39.95 for premium delivery (2-3 working days). At the time I ordered, US purchasers were required to purchase premium delivery, making the price of an ethnicity test effectively $199.

The LivingDNA ethnicity test costs substantially more than Ancestry or 23andMe at $99 or Family Tree DNA at $79, plus shipping. The other vendors products include ethnicity results plus matching to other testers and varying comparison tools. LivingDNA hopes to offer matching between testers in the future.

Terms and Conditions

Thankfully, Judy Russell recently provided a great overview and digestion of Living DNA’s terms and conditions. Please read Judy’s First look: Living DNA terms of use.

Vendors can and do modify their terms and conditions, so always read what any vendor provides, including any fine print.

LivingDNA’s Claims

The page that greets customers provides the following verbiage.

LivingDNA claims twice the detail of other ancestry tests. Detail, which means reference populations and regions in this case, does not necessarily equate to accuracy, but we’ll see how they fare in that department.

LivingDNA is the only company, to date, that offers ethnicity breakdown by regions within the British Isles, based on the POBI (People of the British Isles) project results funded by the Wellcome Trust.

Living DNA claims to have a 3-in-1 ancestry test, meaning ethnicity, mitochondrial and Y DNA, which isn’t exactly true, but it’s not entirely false either. It’s a matter of perception.

LivingDNA is a scan test that scans specified locations in your genome. Haplogroups, both Y and mitochondrial, are defined by specific locations that carry mutations. LivingDNA scans for Y and mitochondrial haplogroup mutations at some level, but they do not offer anything more for Y and mitochondrial DNA than the haplogroup designation. In other words, no detail and no matching. The LivingDNA results are in the same ballpark as 23andMe or the Genographic project, but much less detailed than Family Tree DNA. Ancestry doesn’t offer any Y or mtDNA results, haplogroup or otherwise. To see a detailed comparison of Y and mtDNA testing and who provides what, please refer to Which DNA Test is Best?

LivingDNA does not offer DNA matching, nor do they currently provide a download raw data file so that you can upload your results elsewhere. They indicated in a February Rootstech conference call that they want to move towards both of these goals.

All major vendors (with the exception of Genographic) provide free updates to existing customers when they update their data base, so it’s good that LivingDNA does too.

As for the LivingDNA claim to “view your ancestry through history,” let’s take a look and see what they deliver.

Navigation

Notice on the left hand side of the page that I have two options under Ancestry:

  • Family Ancestry – your ethnicity results
  • Motherline – your mitochondrial DNA results

If I were a male, I would also have Fatherline.

Where ever you are on the site, additional options are always shown on the upper left hand side of the page.

Mother Line – Mitochondrial DNA

First, let ‘s look at my mitochondrial DNA results. Your Motherline options are shown on the bar to the left of your page.

The “Download Results” function has not yet been implemented.

The first Motherline page provides an overview.

I know already that my full haplogroup through full sequence testing at Family Tree DNA is J1c2f. Let’s see what LivingDNA tells me.

Living DNA shows my haplogroup as J1c, which isn’t incorrect as far as it goes, but isn’t complete either.

Living DNA gives me an option to ‘take a tour” of my results, so I did. The heat map, below, shows the locations of my “mother line haplogroup.” Heat maps are hotter, or darker, meaning more intense, where the frequency is greater.

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

I’m not clear whether LivingDNA is displaying a map for haplogroup J1c, or core haplogroup J, given the “hottest” region shown is, surprisingly, Yemen. J1c is typically considered to be European, so surely this map must be referring to haplogroup J plus all subgroups.

The LivingDNA heat map is significantly different than the spatial frequency map for haplogroup J, shown below, published in the academic paper, Genetic Stratigraphy of Key Demographic Events in Arabia published in PLoS ONE in March 2015 by Fernandes et al.

Next, Living DNA discusses the genetic migration for haplogroup J.

Followed by a migration map.

Haplogroup J is shown in Europe here. What happened to Yemen? From this map, it looks like J was born near the Black Sea and traveled directly to Europe, which certainly doesn’t track with the heat map or the PLoS ONE article.

Last, the phylogenetic tree showing the path from Mitochondrial Eve, the first known woman to have offspring that lived to today, to me. I notice in this tree that the migration map above omits haplogroup JT between R and J.

Fatherline – Y DNA

Clearly, being a female, I don’t carry a Y chromosome, but the Y DNA section holds the same pages of information as the mitochondrial DNA section, above, which you also receive if you are a male.

Family Ancestry

The Family Ancestry section is where you will find your autosomal ethnicity results.

You have four options, shown on the left bar.

The first page you will see offers you the option to take a tour and then provides basic information.

In the “What Makes You” section, my results show that I’m 93.4% European and 6.6% unassigned in the rest of the world.

Well, that’s pretty boring, but there’s more.

Click on the “+” to the right of the word “Global” which shows regional results, shown below.

Clicking on the “+” again shows the full breakdown, including the British Isles detail. They could certainly make finding this information more intuitive than “+” and “-“. I suspect a lot of people miss this detail, and if you’re testing for ethnicity, which is all LivingDNA offers today, this IS the important part of the test.

You can click on each region to show history about that region, but I surely wish they had shown a map of the British Isles with the sub-region highlighted instead of the image of the body. It’s impossible to discern which present day counties are included in which LivingDNA regions.

My English ancestors whose locations I know are from Lancashire and Kent, and I can’t tell which of the English regions referenced by LivingDNA would include the locations my ancestors are from.

Ireland, on the other hand, is pretty self-explanatory, but is also a pretty large area.

The Family Ancestry Map shows the locations where your ancestors were found.

Clicking “explore in full” and then the “+” button shows me the following, as does the “Through History” selection.

I’m 72.5% Great Britain and Ireland and 12% North and West European and 6.2% unassigned European which is reflected on the map below, with the darker area having the higher frequency. However, please note that the legend and map are reversed.  On the legend, the Europe unassigned at 6.2% is shown as the darkest shade of green, where on the map, the Great Britain and Ireland shown at 75.2% is shown as the darkest, which is accurate if you are using heat maps.

Click on the “+” sign once again moved to subregions showing the detail of where your ethnicity is found.

Clicking on the region at left shows the associated region on the map.

Please note that some of the features both above and below did not display correctly, or at all, using a PC with either Edge or Internet Explorer browsers.  MACs did better.

Another really easy to miss feature is the “click here” just above the word “standard” which allows you to view your family ancestry at different points through history, beginning with 500 years ago. I really like this video type feature as it shows you the movement of your ancestors with time.

Expanding back in time.

At the bottom of each time period is some history to go along with the time period you’re viewing.

Clicking on the Chart option, shows the following.

How Accurate is Living DNA’s Ethnicity?

I wrote the article “Calculating Ethnicity Percentages” to explain how to determine, based on your known genealogy, what to anticipate in your ethnicity percentages, and to compare the various vendors’ accuracy, although Family Tree DNA has since released an update since that article was published.

For purposes of comparison, I calculated all of my 64 GGGG-grandparent’s ethnicity percentages – each individual accounting for approximately 1.56% of my DNA today.

The following chart shows how LivingDNA compared with my known genealogy.

LivingDNA significantly overestimated my total British Isles. My known and inferred British Isles, based on surnames and colonial American records, is no more than 50.7%, while Living DNA shows it at half again as much, at 75.2%. That’s simply not possible, given the immigration records of my ancestors and the proven locations of their origins in Germany, the Netherlands and France.

I can’t align the known locations of my British or Scottish ancestors with the British Isles regions shown, so I really don’t know if the subregion breakdown within the British Isles is accurate or not. That’s not a problem with the LivingDNA analysis, but is due to the fact that my British Isles ancestry with proven locations is scant.

LivingDNA shows Scandinavian that I don’t show in my genealogy, but they aren’t alone, as we’ll see in a minute when we look at how they stack up to the other vendors.

LivingDNA badly missed the mark for my German which is proven at 25% and my Dutch proven at 14%, although clearly that unassigned European probably comes from that grouping. Living DNA shows Germanic at 9%.

LivingDNA clearly struggled with DNA outside of Europe, as they could not identify any DNA anyplace else in the world. Other vendors have identified Middle Eastern, North African and Native American. Of those, only the Native American is solidly proven.

Altogether, with unassigned Europe and unassigned in the rest of the world, 12.8% of my DNA is unassigned.

Compared to Other Vendors

I’ve updated the chart below to include the LivingDNA results along with the new Family Tree DNA update that occurred in April 2017. The only vendor results which are not the results provided by vendors with a current test is the Genographic project, whose ethnicity results changed in November 2016 when they switched their testing vendor to Helix. I have not retested at Genographic. I have included Genographic in the chart, but excluded them in the comparison because their categories are so broad as to not be functionally comparable to the major vendors and the results are obsolete at this point.

Compared to the other three major vendors, Living DNA was the worst at determining my British Isles ethnicity percent as compared to other regions. Family Tree DNA was the best.

All vendors showed Scandinavian, which is not reflected in my genealogy. The school of thought most prevalent is that Scandinavian is possibly reflective of Viking ancestry that was so ingrained into the population as to remain a constant today. That may be true, at least to some extent. LivingDNA shows less Scandinavian than anyone else, making them the most accurate in this category given that I have no known Scandinavian genealogy.

LivingDNA was second worst in determining my Dutch/French/German heritage if you presume that all of the 6.2% European unassigned fell into that group. If you don’t make that presumption, then LivingDNA was the worst. 23andMe was the best.

LivingDNA had the highest amount of unassigned at 6.6% of any vendor while Family Tree DNA and Ancestry assigned all of my DNA and 23andMe only has .1% unassigned.

LivingDNA missed my Native altogether, while all three other vendors found it, even though it is a small percentage.

Summary

LivingDNA did not perform well in any category relative to ethnicity as compared to the other major vendors with the exception of Scandinavian. Surprisingly, they placed last in the British Isles category which is their area of expertise.

Some of my British Isles heritage is inferred, which could theoretically have raised my genealogical percentage of DNA if I am incorrect in my inference. In other words, in reality, my British Isles heritage % could be even lower than the 50.7% shown on the chart. It’s also possible that amount is slightly low, but my British Isles can’t be much higher because more than 45% of my genealogy is unquestionably proven elsewhere with relatively recent German and Dutch immigrants. So, at most, my British Isles can’t be more than 55%.

If LivingDNA had shown less British Isles than my genealogy, I would have been accepting of that information, given that their specialty is supposed to be British Isles ethnicity and some of my British Isles is inferred. However, LivingDNA was 50% higher than my own calculations, showing 75.2%.

My mitochondrial haplogroup at Living DNA was not incorrect, but it was incomplete, showing only 2 of 4 branches of haplogroup J, as proven by full mitochondrial sequencing. By comparison, the two other vendors who provide the same type of scan tests for mitochondrial and Y DNA, 23andMe shows me as J1c2 and the Genographic Project 2.0 test shows me as J1c2f. Family Tree DNA shows me as J1c2f as well, but their mitochondrial DNA test is more comprehensive and is a separate test altogether, not included in their Family Finder autosomal test.

I can’t correlate my known English genealogy to specific regions as reported by LivingDNA because my only ancestors whose British Isles locations are specifically known came from London, a melting pot from all over the rest of England, Kent and Lancashire, so I can’t pass any judgement as to the relative accuracy of LivingDNA’s British Isles breakdown except to say my known Irish appears to be accurate.

What I can say is that for anyone who doesn’t have primarily British Isles DNA, or entirely British Isles DNA, I would not recommend this test given the issues noted above. Additionally, LivingDNA is substantially more expensive at $149 than the competing products at $99 (23andMe and Ancestry) and $79 (Family Tree DNA,) all of whom also include matching.

For this test to be useful, the tester would need to be nearly or entirely British and have their genealogy proven to specific regions within the British Isles in fairly recent generations to ascertain accuracy. For me, with a high level of American colonial DNA mixed with relative recent ancestors from western Europe, the test fared poorly.

I would be very interested in knowing the accuracy from the standpoint of multiple testers whose ancestors are entirely from the British Isles and have proven an extensive genealogy back through their 64 GGGG-grandparents. In other words, are the regions within the British Isles accurate?

Keep in mind that all ethnicity tests are really estimates and vary based on the reference panels used by the vendor and the algorithms the vendor uses internally to assign your DNA to specific ethnicities.  LivingDNA points out on their website that inheritance is not a constant at 50% per generation (of ancestral DNA being passed to the next generation) and ethnicity testing is not an exact science – and they are right, on both counts.

In other words, your mileage will vary – a lot.

Which DNA Test is Best?

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

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

Testing Goals

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

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

We will be discussing testing for:

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

We will be reviewing the following test types:

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

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

  • Additional Vendor Considerations

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

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

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

The Big 3

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

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

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

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

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

A Word About Third Party Tools

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

Let’s get started!

Ethnicity

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

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

Yep, same person, different ethnicity breakdowns.

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

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

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

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

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

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

Let’s look at each company separately.

Ethnicity – Family Tree DNA

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

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

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

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

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

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

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

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

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

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

Ethnicity – Ancestry

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

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

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

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

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

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

You can read more about Genetic Communities here and here.

Ethnicity – 23andMe

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

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

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

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

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

Ethnicity Summary

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

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

Adoption and Parental Identity

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Adoptee Y and Mitochondrial Testing

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

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

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

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

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

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

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

Adoption Summary

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

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

Genealogy – Cousin Matching and Ancestor Search/Verification

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

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

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

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

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

Genealogy – Autosomal –  Family Tree DNA

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

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

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

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

Unique autosomal tools provided by Family Tree DNA are:

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

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

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

Genealogy – Autosomal – Ancestry

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

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

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

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

Unique tools provided by Ancestry include:

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

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

  • New Ancestor Discoveries (NADs), which are similar to Circles, but are formed when you match people descended from a common ancestor, but don’t have that ancestor in your tree. The majority of the time, these NADs are incorrect and are, when dissected and the source can be determined, found to be something like the spouse of a sibling of your ancestor. I do not view NADs as a benefit, more like a wild goose chase, but for some people these could be useful so long as the individual understands that these are NOT definitely ancestors and only hints for research. Subscription required.
  • Ancestry uses a proprietary algorithm called Timber to strip DNA from you and your matches that they consider to be “too matchy,” with the idea that those segments are identical by population, meaning likely to be found in large numbers within a population group – making them meaningless for genealogy. The problem is that Timber results in the removal of valid segments, especially in endogamous groups like Acadian families. This function is unique to Ancestry, but many genealogists (me included) don’t consider Timber a benefit.
  • Genetic Communities shows you groups of individuals with whom your DNA clusters. The trees of cluster members are then examined by Ancestry to determine connections from which Genetic Communities are formed. You can filter your DNA match results by Genetic Community.

Genealogy – Autosomal – 23and Me

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

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

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

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

The one genealogy feature unique to 23andMe is:

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

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

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

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

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

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

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

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

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

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

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

Genealogy – Autosomal Summary

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Genealogy – Y and Mitochondrial DNA

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

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

Y-DNA Testing for Males

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

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

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

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

Family Tree DNA provides three types of Y DNA tests.

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

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

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

Mitochondrial DNA Testing for Everyone

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

Matching can identify family lines as well as ancient lineage.

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

Overall Genealogy Summary

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

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

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

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

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

 

Testing for Medical/Health or Traits

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

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

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

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

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

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

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

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

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

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

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

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

Traits

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

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

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

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

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

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

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

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

 

Additional Vendor Information to Consider

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

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

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

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

Family Tree DNA does not sell your DNA or information.

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

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

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

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

Which Test is Best For You?

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

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

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

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