I saw from following DNASleuth’s blog that Ancestry has a new ethnicity feature, wherein your received ethnicity is assigned to either Parent 1 or Parent 2. So, naturally, I had to check it out. Ethnicity estimates were also revised!


My dad formerly (as of last week) was listed at 100% Irish. He is no longer. Now he’s 90% Irish, with the remaining 10% being Scottish and Welsh. And, honestly, in the past, AncestryDNA has shown him with Scottish, Welsh, and even English ethnicities. It all depends on the calculation at the time, I guess.
All that said, I believe this estimate is quite in line with the paper genealogy, and the birthplaces of my great-grandparents. I have 4 Irish/Celtic great-grands, 2 Italian great-grands, 1 great-grandparent whose parents were born in and immigrated from southern Denmark, and one great-grandparent whose line in the U.S. extends back to early 1700s and is largely of German and English descent.
If you have taken a DNA test at Ancestry, do go check out the new info!
