AncestryDNA posted Ancestry® Delivers More Precise Ethnicity Estimates Powered by the World’s Largest Consumer DNA Network today.
When I checked my DNA Story on AncestryDNA, I noticed that my ethnicity estimates have changed a bit. Here is my latest (11 September 2020) ethnicity estimate:
So I've lost 17% from England, Wales and Northwestern Europe; I've gone from 5% Ireland and Scotland to 19% Scotland and 7% Ireland; I've gone from 3% Sweden to 7% Sweden, and from 6% Norway to 5% Norway.
My estimated ancestral origin estimate from my known ancestors in about 1600 CE is:
* 68% British Isles (but just 1% to 2% from Ireland and Scotland)
* 24% Germany/Switzerland
* 1% Holland/Belgium
* 1% France
* 6% Unknown (perhaps some are French, some are English)
My last comparison of ethnicity estimates from all of the providers is in https://www.geneamusings.com/2017/05/comparison-of-my-autosomal-dna.html.
As we all know, these are ESTIMATES based on reference populations. My DNA hasn't changed, but the ethnicity estimates of five different companies are all different because they use different reference groups. I still think the 23andMe estimate is closest to my ancestral estimate.
