This is old, but I didn't know till a year ago. I am 1/256 aboriginal. I asked my aunt, she said "you didn't know?" The was in the kitchen once when she was a kid, and her mother said, quit standing like that. The stork position. Her grandmother said, leave her alone , she comes by it naturally. Her brother was a dead ringer for an aboriginal albino. My other aunt sent me a picture of my uncle, he is albino with the wide nose, etc. My father looks like he came over on the MayFlower. As do I, but since my great grandmother (8 times) was an albino from somewhere near australia, I would believe it. All of us who have sent in our spit, for the tests, have the same results. 1/256. So we are. My grandmother's side came 10 years after the Mayflower. So we are all kinds of stuff.
Question...Caucasian (Polish/English/German) guy here with no Native American DNA per 23andme test.
However...it says I'm .01% (one tenth of one percent) Sub-Saharan African.
...this would be expressed as a fraction of 1/1000...decimal of .001
...how many generations back is that or can that even be calculated in years?
...assuming this is from way back (pre-slavery) before America was even a country correct?
Interesting question. The Romans used troops from Africa in their armies. Traces of African DNA going back that far in time has been found in England, for example. Do you have a Brit background? I don't know who else the Romans fought in Europe. Take it from there...

Yep...23 and me says...
50% Polish 22% English
17% German
2% Italian
1.2% Spain/Portugal
0.2% Scandinavian 0.1% Sub-Saharan African
--the remainder being "Broadly European"
Not sure how to track down that tiny African component if it can even be done?

That's from Y-DNA, which has nothing to with autosomal DNA and ethnicity reports, which this wouldn't show up on. The ethnicity report isn't going to include data from one single ancestor from Roman times. Coming from a single ancestor, 0.01% would be about an 11th-12th great grandparent, probably approximately during the 1500s, hardly Roman times. But more than likely, it's just noise, a false positive. It's very common.
It's probably just noise, a false positive. You really shouldn't assume any small percentage, especially a fraction of a percentage, is conclusive.
True...that's what I was thinking. I may be wrong, but feel 1% or more would be legit as a general rule...unless you could somehow track down those fractions of a percent.
