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

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!

Did you hear what has been discovered about the remains of three Caribbean slaves found on the island of St. Martin? Scientific techniques identified them as two males and one female, all between 25 and 40 years of age, who were buried around the mid-to-late-1600s.
But where were they from? It took DNA to help answer that question, with a process very similar to that used to identify our ethnic origins in DNA testing today.
First, scientists had to retrieve DNA from the sun-bleached, humidity-soaked remains. Their first stop: the teeth. Traditional DNA extraction and analysis methods failed, but results were found with a new method called whole genome capture. You can think of this method like unleashing an army of vigilantes on your DNA, each one tasked with bringing back a particular portion for analysis. While this method was far more successful, it still was only able to find 7% of the DNA of the best sample.
Second, they needed a reference population: a group of Africans to compare these results to in order to find a match. There is such a group assembled, which contains 11 of the likely 50 population groups that contributed to the slave trade. Keep in mind that in Africa, especially at that time, populations were not defined by geography as much as language. So when you hear African populations defined, it is often according to their relationship to one very large language group in Africa, called Bantu. There are really two groups: those that are Bantu speakers, and those who are not.
Even with the incomplete DNA and the limited reference population, the group was able to determine that two of the slaves belonged to non-Bantu speaking tribes, likely in present day Ghana or Nigera, while the third was Bantu speaking, possibly from northern Cameroon.
Finding ancient samples such as these, and having technology enough to analyze them, if even just a small part, has huge implications for the future of genetic genealogy, and family history. These kinds of genetic techniques can help place you in a genealogical relationship with another person, where your traditional genealogical methods could not. Family history, the substance and story of your relationship, inevitably follows.
I think Fatimah Jackson, a biologist and anthropologist at Howard University, said it best. “It seems to me that, as a scientist, the best way to ‘honor’ these unfortunate individuals is to allow their story to be told,” she says. “The story of a few can illuminate the condition of the masses.” We may never know the names and specific life histories of this woman and two men any more than we already do. But DNA has gotten us closer to telling at least some of their story. Click here to read the scientific study.

Over million in grants has been awarded by the National Archives (U.S.) to digitize important historical documents. Here’s how the 
awards break down:
- $1.1 million to “nine publishing projects from the U.S. Colonial and Early National Period, including the papers of Benjamin Franklin, George Washington, John Adams, Thomas Jefferson, James Madison, Dolley Madison, and John Jay. Projects to record the Documentary History of the Ratification of the U.S. Constitution and the Documentary History of the First Federal Congress also received funding”
- Nearly $700,000 to “State and National Archives Partnership (SNAP) grants to enable 28 state historical records advisory boards to carry out their mission to support archival education and strengthen the nation’s archival network;”
- Over $500,000 to 7 projects to “digitize World War II Oral History files; the papers of Leo Szilard, the nuclear physicist; the papers of General Oliver Otis Howard, Civil War general, Commissioner of the Freedman’s Bureau, and third president of Howard University; Historical Collective Bargaining Agreements from the 1880s through the 1980s; the Center for Jewish History’s American Soviet Jewry Movement collections; Early Connecticut manuscripts; and 19th century trademark files in the California Archives, including the original trademarks and specimens from Levi Strauss & Co. jeans, 19th century medicines and tonics, and the original trademark registered to Anheuser Busch for its Budweiser lager.”
As you can see, there’s a lot in there to appeal to family historians. Maybe not so much the Levi Strauss and Budweiser artifacts, but I could see many of us being interested in the World War II oral history files; the papers of the Freedman’s Bureau Commissioner; the Center for Jewish History’s files; those early Connecticut manuscripts and more.
The National Archives’ press release doesn’t say where these digitized files will end up. But I’m guessing at least some will eventually be made available on Founders Online, an award-winning database on the papers of “America’s Founders.”
