I did both 23andMe and Ancestry. 23andMe has me at 72.8% black (60% West African), 24.3% white, and 2.5% Asian/Indigenous American. Largest ethnic groups are Ghanaian/Liberian/Sierra Leonan (23.9%); Nigerian (22.8%); Congolese/Southern East African (10.7%)...
Ancestry has me at 73% black, 26% white, and 1% Asian. Ancestry specifically identified my DNA communities to Louisiana Creoles which is accurate, and both have matched me with more people from Louisiana than anywhere else, both white and black people. And I've never been to Louisiana a day in my life, but my 72-year old maternal grandma grew up in Arkansas, and her father was from Louisiana and they were there often when she was a child. Didn't find out until 2017 or so, thru her, that we are Creole of Color, so it made all the Louisiana matches make sense...
The general racial splits line up with each other on both, so I figure it's accurate. I got the 23andMe in Dec 2015 and Ancestry in Summer 2018; was stunned initially to see that there's that much European in my line, needed a second opinion from Ancestry. I have white relatives by marriage, but none that I actually know I'm blood-related to. So that ~25% number was odd to me---->then I found out about my Creole ancestry and it all made sense, since Louisiana Creoles are a multiracial people. That, and the fact my paternal grandma had a white mom, helped me make sense of it...
Everyone by blood I know in my family is black but all this stuff was cool to find out anyway!
Interesting...
