If you haven’t logged in to your Ancestry DNA account today, you might want to go take a peek. They released an update to the ethnicity estimates, making some adjustments and refining some regions to be a little more specific.
Here is mine:
Compared to my previous numbers:
You can see that they’ve refined some of the regions such as “Great Britain” to “England, Wales, & Northwestern Europe.” And they’ve split out Wales from the previous category of “Ireland/Scotland/Wales.” “Europe West” has been refined to “Germanic Europe.”
This refinement makes more sense from what I know from documentary research and it is good to see updates to the data.
