AncestryDNA’s Breakthrough for West African Ancestry

AncestryDNA announced last week that it has been able to identify six unique historic populations in West Africa. It’s a breakthrough they call a “finer-resolution genetic ethnicity estimate for individuals with West African ancestry.” They have even used this technology to start connecting the dots between those groups and millions of African-Americans whose ancestral paper trail was annihilated during the era of slavery.

For this latter development, the AncestryDNA team uses the “cluster genealogy” approach: the concept that people from the same location often migrated to the same areas. Of course, slavery forced apart families and other natural migration groups, both in Africa before the crossing and in the U.S. or other destinations. And the few records that remain of many of these folks and their enslaved descendants don’t include full names, place of origin or other data we rely on to make family connections.

It’s encouraging to read that AncestryDNA has had some success hooking up regional groups of African-Americans with specific areas of Africa. “Though this project is still in its infancy, the science team has made some progress,” AncestryDNA reports. “First, we looked at the birth locations of individuals in the trees of all African Americans. Then, we looked for locations where, relative to all African Americans, there appeared to be an over-representation of birth locations in trees of individuals with a particular West African ancestry.  For individuals with Senegalese genetic ethnicity, we found what seems to be an over-representation of birth locations in South Carolina and Georgia in the 1700’s and 1800’s.”

How to Find U.S. Digital Libraries and Archives

Ever wish there was a really easy directory for U.S. digital libraries and archives, organized by state with great commentary about the content? There is. But it’s not in a place most genealogists would look.

Open Education Database.org has a blog post called “250+ Killer Digital Libraries and Archives.”  The post is a LONG annotated list of digital libraries and archives that don’t require library memberships, subscriptions, etc. to access. (In other words, open access.) It’s organized by U.S. state, so you can scroll down to the states of most interest to your research.

Digital archives and libraries give us remote, fingertip access to original and published materials we might never otherwise know about or be able to access. Look here for books, government documents, photographs, manuscript items, memorabilia, audio recordings and more. This is a great resource for genealogists. Click the link above to get all the info.

Disaster Preparedness for Genealogists Past 3: Protect Precious Originals

fire_hydrant_spray_water_300_clr_11472It’s time for the third part of our disaster planning process in honor of National Preparedness Month in the United States. Two weeks ago, I talked about assessing your home archive and research files and prioritizing the items you want to protect. Last week, we talked about making copies of important originals and other valuable items. This week:

PROTECT PRECIOUS ORIGINALS. After you’ve duplicated your originals, take steps to preserve them. How exactly you do this depends on what you’re protecting; how much time and money you’re willing to spend; and how you plan to store or display them. The core strategy is to store them in appropriate archival materials away from direct light and extremes in temperature and humidity. No damp basements or hot attics! But what materials constitute safe storage are different for paper items, different types of photos or cloth, and electronic items, so you need to do a little research. (Hey, we genealogists are good at that!)
