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.

INTERVIEW: MELISSA BARKER, THE ARCHIVE LADY

Melissa Barker is a Certified Archives Records Manager, the Houston http://www.honeytraveler.com/buy-antibiotics/ County, Tennessee Archivist and author of the popular blog A Genealogist in the Archives and bi-weekly advice column The Archive Lady. She has been researching her own family history for the past 27 years.

Preserve your own family archive

Items in danger include original items in attics, basements, etc.

What to preserve first? The most precious and original items you have!

Restoration tips:

  • Clean documents and photos with archival sponges. Lay the item perfectly flat. Gently place a finger or hand to hold it steady. Work with the sponge from the center outward, in small sections.
  • Keep two-dimensional items as flat as possible.
  • Encase fragile items in Mylar sleeves (buy from archival supply companies).

Visiting an archive:

  • Call ahead! Don’t trust the operational hours from the website. Ask about parking ? it’s often very limited. Ask ahead about access to archival items of interest.
  • Archive etiquette: Follow the rules. Be courteous when working with staff.
  • Museums, societies, archives, and libraries may all have collections in back rooms you can’t see?but you can ask for them.
  • Vertical Files – in folders in cabinets
  • Manuscript Collections – underused in genealogy! Ask for finding aid.
  • Loose Records – the working papers of a court case, for example
  • Unprocessed Records – not yet incorporated into the official collection

Tips for using your mobile devices in archives:

  • Ask for procedures for taking photos with your own device. There may be rules against this or a use fee.
  • Capture the source information by photographs: cover page, page number, folder, box number, manuscript collection name, etc.

DNA Down Under: AncestryDNA in Australia and NZ

DNA down underAncestryDNA test kits are now available to purchase in Australia and New Zealand, according to a recent statement from Ancestry. These two countries join the UK, Ireland and the US in having access to AncestryDNA’s popular autosomal kits.

DNA testing for genetic reasons isn’t new Down Under. Your DNA Guide Diane Southard blogged on our site last fall about a National Genographic Project that looked at the mixture of genes among residents of Wellington, New Zealand. They determined that “the original Polynesian population and a small East Asian population are certainly the minority among a predominately Western European population group.”

Additionally, Family Tree DNA has a New Zealand DNA Project that anyone with NZ roots can join. It has three DNA groups for Australia: one for adoptees, one for descendants of settlers and one specifically for descendants of early buy medication for depression online convicts (Australia was originally a British penal colony). So AncestryDNA in Australia and New Zealand represents just one more option for this part of the world.
