mtDNA Testing for Genealogy: A Study on Ancient Ponytails
Sometimes history provides us with a situation that is just too outlandish to be false, like this one on mDNA testing for genealogy by using ancient ponytails! In these lucky, true-to-life conditions, clues to help us unravel genealogical mysteries and tell our own crazy stories might just be found.
English Mutineers Create Endogamous Population
Do you know the story of the mutineers of the British HMS Bounty? Rewind back to the year 1789, three weeks into the 10-month journey to deliver their cargo from Tahiti to Jamaica. Twenty-five crew members, led by first mate Fletcher Christian, ousted their captain and loyalists. Then, they turned back toward the Tahitian paradise where they had spent the previous 5 months. For their crime of mutiny, they were hunted down. While 16 were later captured in Tahiti and returned to England, 9, including Christian, hid on the tiny island of Pitcairn.And when I say tiny, I mean tiny. 1.75 square miles tiny.
But considering that 9 English mutineers, their Tahitian brides, and a couple Tahitian men were the founding population for this island, it provides an amazing genetic and genealogical view into endogamous populations.
The Proof is in the Pigtails
This fascinating tale is about to get richer, as ten pigtails of hair claiming to be from some of the original mutineers and their wives, have recently been acquired by the Pacific Union College’s (PUC) Pitcairn Islands Study Center in California. The King’s College London has contracted them to perform DNA testing.
Pay close attention to this next part: Researchers are going to conduct DNA testing on the hair samples. But this does not mean you are going to be able to test the locks of hair stowed away from one of your ancestors!
Why, you ask?
First barrier: Cost. This process of trying to extract DNA from a hair sample, especially a very, very old hair sample is meticulous work. It will cost the average consumer a pretty penny. And, you may not be able to find a DNA testing company who wants to do it for you. All major genetic genealogy companies will just flat out tell you “no.” Most paternity testing companies will require your hair has the root attached. In fact, in my quick search, I can’t even find one DNA testing company that will attempt to get DNA from your lock of hair.
Second barrier: Results. Even if you could get a lab to extract the DNA for you, the only available DNA type retrieved from a cut piece of hair is mitochondrial DNA (mtDNA). The mtDNA will trace a direct maternal line. This is opposed to the YDNA that traces a direct paternal line and the autosomal DNA which traces both sides of your family tree. Even if they do get mtDNA from your sample, it is likely to be damaged and incomplete. Therefore, the best you will likely get is an assessment of your deep ancestral origins.
For you, that might not be quite enough to determine and document your family history. But for those interested in verifying this story of mutineers settling in the Pitcairn islands, it might be.
Will it Work?
If they do get mtDNA from the 10 pigtails, they will get 10 mtDNA lineages represented. Those stemming from the mutineers should have their deep origins in Europe, while their Tahitian brides will have a very different mtDNA signature. Likewise, if an mtDNA signature can be obtained, then the mtDNA of those still living in Pitcairn and nearby Norfolk (where many went in 1857) should match these pigtails. If it does, they can measure how many of the current residents are directly maternally related. Of course, in order to truly verify the claims, some serious genealogy work must be completed.
I will be watching this story closely over the next few months as research progresses. If successful, this will be another victory for the rarely celebrated mtDNA. This study shows that if your goals are understanding deep heritage, or testing out a particular hypothesis on your maternal line, mtDNA can be a useful option.
While the DNA studies you read about in the paper won’t always be something you can learn from, others are. Take for example the stories I shared several months ago on the Genealogy Gems podcast and blog about DNA confirming the love affair of President Warren G. Harding and the story of how experts proved it was King Richard III buried under that parking lot. You can definitely learn about using DNA for genealogy from these very public examples!

DNA for Adoption: Katie’s Genetic Roots Were Closer Than She Thought
This story of DNA for adoption research tells how one Genealogy Gems listener discovered biological roots that were closer to her adopted home than expected.
You never know what you’re going to learn when you start researching the biological roots of an adopted ancestor. And that was certainly the case for Katie from Pacifica, CA. Recently, she wrote me to share her story of researching an adopted ancestor. Understandably, people hope for a happy ending when using DNA for adoption research. But in Katie’s case, it may be just the beginning. Here’s why:
“When I set out on this geni-journey, my goal was to find my grandfather’s birth parents. [He was adopted.] But as I read all the old family letters and newspaper clippings, I found myself getting so attached to his adoptive family. I was saddened that we weren’t blood-related, because I felt so connected and proud of them.
My mother and I decided to take the AncestryDNA test, not sure what we’d find. When we got the results back, the strangest thing happened. My closest match with a family tree was a descendant of my grandfather’s adoptive grandfather.
My other closest match was adopted. He had been searching for his birth parents since the 1970s. When I called my adopted match, I think we were both excited and confused, not really sure how we’d be able to help each other in our search. As we compared notes, everything started clicking together. He began to cry. This mystery cousin of mine was no cousin at all. He was my grandfather’s half-brother. He was my great uncle, who was raised by a different, unrelated adoptive family!
My grandfather, Joseph, turned out to be the biological nephew of his adoptive mother, Angela. His birth father was Angela’s brother, Paul. Angela’s own son tragically died of a ruptured appendix at age 4. Her husband, Ralph, was a merchant ship captain who traveled regularly all over the world, but most commonly between Oakland, CA and Brooklyn, NY.
According to family lore, less than a year after their son’s passing, Ralph mysteriously brought a freckly little boy (my grandpa) home to Oakland with him from Brooklyn, shocking his wife with this child she was suddenly expected to raise. Can you imagine that boat ride, all the way through the Panama Canal, as a confused orphan? And oh the family rumors that started!
Using DNA, we were able to put those rumors to rest. I’m not sure if Angela ever learned the truth– I’m not sure what Ralph told her, whether she even knew she was raising her own brother’s boy. All those years grandpa never asked who his birth parents were because he was afraid of hurting the family’s feelings, and little did he know he was being raised by his aunt the whole time. He probably met or at least wrote to his father without ever knowing it.
I have now met both my great half uncle, whose adoptive name is Bill (born Paul, in honor of his deceased birth father)– he lives in NY– and his son [Tom].
At 69 years old, that was his first time meeting a blood relative. I also connected with two living cousins in their 90s
thanks to their very sweet children and nieces. I had photos of them from 1935, standing with my grandfather when he was only four years old, having no idea who they were until I started doing research.
I couldn’t believe they were still around! I was able to meet them last year. I was also able to provide them with photos of their father, as they had only
a few of their own.
I now send regular emails to the whole reunited family to update them on my genealogy discoveries.
I went on an homage journey to Prince Edward Island, the place my adoptive and birth great grandparents grew up, and was able to lay flowers at the gravestones of our long lost family members. The house they grew up in was still standing. Still being lived in, even!
It was such an amazing discovery after feeling so mysteriously close to that family, to know that it wasn’t all in my head. And to find out I had an uncle still living? Amazing.”
When Katie’s story landed in my inbox, it reminded me how lucky I am that so many of you share your personal, and inspiring stories! Thank you to Katie for giving us permission to share this inspiring story about using DNA for adoption research.
