Beat me to it. I would guess that is the connection and start from there.

Much like someone who is African-American matching with a 100% European American.

True, but doesn't the average African-American in the US have about 22% European DNA. My guess is this distant Asian cousin, might of had their European DNA diluted out over time. That 19 centimorgans across 1 DNA segment, isn't going to show up as 1% of any of the 379 European Regions Ancestry has in their reference panels, will it?

African Americans typically have some European ancestry. My husband has approx 30%. He has numerous white matches, many of which show 100% European ancestry. This wasn't a surprise to us since slavery is part of his history however the number of white matches he has was surprising.

In my case, the match and I didn't have any shared ethnicity nor any shared matches. However since reading some of the replies it seems that most likely this person has some very far back British heritage that probably just did not register on his test.

What I think is wonderful about doing these DNA tests is the amount of history we are all learning through this process :-)

Thanks for that bit of info! That makes sense! And no we have no shared matches.

Uncomfortable topic. It's not uncommon. 100% European American who has ancestry on this continent since colonial times might (I do) have African American cousins.

It is uncomfortable. I hope I didn’t derail the thread though.

Interesting - have you both uploaded to Gedmatch? If so, what does the one to one comparison say?

This match is on 23andme so I am able to use the chromosome tool there. However I am on Genesis and don't see him there (but so many have an alias there that it would be hard to confirm).

Hang on, since this is 23andMe, the shared segment doesn't happen to be on the X chromosome, does it? Because if so, then this could be identical by state (false positive) match after all. I think 23andMe are one of the ones that report X matches even if they don't share any autosomal DNA, which in my opinion isn't a good idea. There is less recombination on the X chromosome, meaning larger shared segments can still be identical by state, especially if there's no shared autosomal DNA. Most companies don't use shared X-DNA to determine a match or relationship degree for this reason, but I think 23andMe is one of the ones that does.
