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.

We Dig These Gems! New Genealogy Records Online

We learn about great new genealogy records online every week! On Fridays we round up a few for you. Watch for databases and documents that your ancestors might appear in–and get inspired by the types of records that may be out there for your family, waiting for you to discover. This week: a photo archives for Canadian Mennonites, a Georgia state newspaper collection, a genealogy index for a northeast Ohio archive and WWII Cadet Nursing Corps membership cards (US).

CANADIAN MENNONITE PHOTO ARCHIVE: A new database is now online with over 80,000 images of Mennonite life from across Canada and dating back to 1860s. A press release says that the archive “is a project of the Mennonite Historical Society of Canada  and includes Mennonite archival partners in British Columbia, Alberta, Saskatchewan, Manitoba, and Ontario.” An online ordering system allows visitors to order image copies for noncommercial use.

GEORGIA NEWSPAPERS: The Digital Library of Georgia has launched an archive of north Georgia historical newspapers. “The North Georgia Historic Newspapers Archive provides online access to six newspaper titles published in three north Georgia cities (Dalton, Gainesville, and Rome) from 1850 to 1922. Consisting of over 33,000 newspaper pages, the archive provides historical images that are both full-text searchable and can be browsed by date. The site is compatible with all current browsers and the newspaper page images can be viewed without the use of plug-ins or additional software downloads. The archive includes the following north Georgia newspaper titles: Gainesville News (1902-1922), Georgia Cracker (Gainesville) (1894-1902), North Georgia Citizen (Dalton) (1868-1921), Rome Courier (1850-1855), Rome Tri-Weekly Courier (1860-1880), Rome Weekly Courier (1860-1878). The Digital Library of Georgia will add additional titles from the region over time.

OHIO GENEALOGY INDEX. The Western Reserve Historical Society in Cleveland, OH has created an online Genealogy Index to some of its most valuable and unique genealogical records, including original funeral home and Bible records. Also in the index are Jewish marriages and death notices, an index of names in a significant African-American manuscript collection, a 1907 Cleveland voter registration index, a photo database of Cleveland military personnel from WWII and the Korean War and a biographical sketch name index. Currently, there are about 320,000 records in the index; more are being added on an ongoing basis. The Society primarily archives records relating to Cleveland and northeast Ohio. Soon to be added are indexes to the 1870 mortality census for Ashtabula, Ohio and indexes to several church records collections.

WWII CADET NURSING CORPS (US): The WWII Cadet Nursing Corps Card Files, new on Fold3, contain membership cards of women who joined. According to Fold3, the cards “are organized by state, nursing school, and cadet name. Some cards include the date of admission to the school, date of admission to the corps, and date of graduation (or date of other reason for termination from the school). Others contain details like the woman’s marital status, father’s/husband’s name and profession, years of college completed, place of residence, and how they heard about the corps. Still others also record the woman’s age in addition to the previously mentioned information.”

To search for images you can use without violating copyright, do a keyword search in Google Images (or just do a keyword search from Google’s home page and then click “Images” above your search results). Click Search Tools. Another toolbar will pop up. Click “Usage rights.” You can sort search results by those that are labeled for reuse in different ways. You won’t capture every copyright-free image, but hopefully you’ll get a decent selection of options!

Did your family follow the usual path? Mapping U.S. Migration Patterns

NYT Mapping Migrations Map Screen Capture

Mapping Migration in the United States. From the New York Times. Click to go straight to the source!

The U.S. has long been typified as a nation of restless wanderers. Are we still? Well, it depends on where in the U.S. you are from.

A new interactive infographic on the New York Times website looks at U.S. migration patterns: where residents of each U.S. state in 1900, 1950 and 2012 were born. According to the accompanying article, “You can trace the rise of migrant and immigrant populations all along the Southwest, particularly in Texas and Arizona, the influx of New Yorkers and other Northeasterners into Florida starting in the 1970s; and the growth in the Southern share of the Illinois population during the Great Migration.”

“In 1900, 95 percent of the people living in the Carolinas were born there, with similarly high numbers all through the Southeast. More than a hundred years later, those percentages are nearly cut in half. Taken individually, each state tells its own story, and each makes for fascinating reading.”

If you live in the U.S. now, click on your state to zoom in. You’ll see the statistics more fully represented. How many natives of that state still live there? Where else are its residents from? Where do you fall in? I am one of less than 1% of Ohioans who was born in a western state (excluding California). My husband and children are among the 75% of Ohio natives who still live here.

It might surprise you how little–or how much –your fellow state residents have been on the move. Now turn back the clock by clicking on the 1900 or 1950 maps. How did your family fit the norms for the time?

DNA Health Testing Back on U.S. Horizon for 23andMe

DNA shopperA direct-to-consumer genetic test, the first of its kind to be approved in the U.S., may become available through 23andMe, according to letters recently received by 23andMe customers. The FDA-approved test is designed to check to see if you are a carrier for Bloom Syndrome, a disease most common among those of Jewish heritage.

This is a huge step for 23andMe, which lost the ability to report health related information to its U.S. customers in November of 2013 and has been working to restore it ever since. Health testing for 23andMe customers is currently underway in Canada and the UK. This is the first big step toward restoring the health component of their testing to those of us in the U.S.

This kind of direct to consumer (DTC) testing is going to be a huge industry. For those of you with any experience getting a genetic test ordered and executed through your doctor’s office, you know this process can be lengthy, not to mention very expensive.

As more and more genetic tests are able to be offered directly to you via commercial companies, there will be more competition for this kind of test, meaning that there will be more research conducted into the cheapest way to produce this kind of test. Since these are the same kinds of procedures used for our genetic genealogy testing, more research and lower costs for DTC tests means cheaper genetic genealogy tests.

In further news, 23andMe announced their intention to enter the pharmaceutical industry and begin to develop medicines to address some of the diseases and conditions it has engineered genetic tests to identify. This is a good reminder that a company we have previously lumped with the other two purely genetic genealogy companies (Ancestry and Family Tree DNA) is very much a medically-minded company.

While 23andMe does provide information regarding your ancestral heritage and provides a list of genetic cousins, it is important to realize that this company’s interest in your family tree is focused more on your family’s ailments than its ancestors. (Click here to read a Forbes article about this development, and click here for more information about the laws that are in place to protect your genetic data, including health testing.)

Share World War I Family History

flagTo commemorate the centennial of the First World War, and to mark the last full month of the exhibition Myth and Machine: The First World War in Visual Culture, the Wolfsonian at Florida International University (FIU) created a special Tumblr for sharing family stories, WWI memorabilia, and genealogy research tips called #GreatWarStories.

I first crossed paths with FIU’s Digital Outreach Strategist Jeffery K. Guin in 2009 when he interviewed me for his Voices of the Past website and show. Jeff was an early innovator in the world of online history, and he’s now brought those talents to the Wolfsonian, a museum, library and research center in Miami that uses its collection to illustrate the persuasive power of art and design.

The Wolfsonian team of historical sleuths is inviting the public at large to help them unearth the forgotten impact of the Great War by posting family facts, anecdotes, documents, and photographs. They were inspired by their current art exhibition Myth and Machine: The First World War in Visual Culture which focuses on artists’ responses to the war. They hope that #GreatWarStories project at Tumblr will be a “living, breathing digital collection of personal WWI stories, photos, documents and letters compiled in remembrance of the transformational war on the occasion of its centennial.”

Great war

Jeff asked me to join in on this buy add medication online history crowd-sourcing effort, and it was easy to comply. Several years ago  in going through the last of my Grandmother’s boxes, I found a booklet she had crafted herself called The World War.As a high school student, and daughter of German immigrant parents she set about gathering and clipping images from magazines and newspapers, depicting this turning point in history. I’ve been anxious to share it in some fashion, and this was my opportunity. Here is the result:

Do you have a piece of World War I history hiding in our closet? Why not join in this experiment in storytelling, sharing and curating, and share World War I family history?

Here are some ways you can contribute:

  • Sharing the story of your family’s WWI-related history through photos, documents, or anecdotes (possibilities include guest blogging, video/podcast interview, or photo essay)
  • Using your expertise and unique perspective as a launching pad for discussing the war’s impact in a different or surprising way
  • Alerting the museum to related resources or materials that would dovetail with the mission of the project

To see the living, digital collection, visit http://greatwarstories.tumblr.comIf you would like to participate, send an email to greatwarstories@thewolf.fiu.edu and the Wolfsonian team will be in touch to discuss storytelling ideas.
