Ancestry recently updated the DNA profiles of their customers. I've seen a number of postings on Facebook and on blogs about how things changed. I checked mine yesterday. Originally, my estimate was very generic and boring, but not unexpected. My own research reveals that virtually all of my ancestors came from England with a sprinkling from Ireland, Scotland, Wales, and a lone French Huguenot.
I was hoping to at least reveal a little bit of biodiversity from the Viking, Germanic, or Norman invasions. When the update was released, Ireland was separated from Great Britain and more detail was added. This did, indeed, reveal some Scandinavian, Western European, and Irish ancestry. What was completely unexpected was the 5% from the Iberian Peninsula. The site says that Iberian DNA is common among those with British ancestry. Here are my updated results.
I am just beginning to understand some of the uses of DNA in genealogy. I do know that the more information that is put into the system, the more refined the results will be. I like the fact that Ancestry.com will continue to refine my results without charging more money for each update. I was a bit disappointed that the original results were not more specific but this is more interesting and reflects what I know about my origins. I look forward to learning more and more about DNA and how to interpret and use DNA results in genealogy.
