Huh, interesting.

My father's family is Portuguese, and when I did one of those DNA test things, I got some Western African DNA in the results. So - not entirely implausible, the Portuguese sailors got around.

"West African DNA" doesn't really mean much of anything. There are genetic traits that are frequently associated with or more common in certain population groups, but they're not actually exclusive to those groups. So you could have West African ancestry, or you could have a couple gene sequences that also happen to turn up frequently in the segment of West African people that particular testing company has sampled.

I have no idea how they do it or anything, so i'll take it at face value, and consider that sailors got up to a lot of stuff in foreign ports, including bringing home non-European and mixed brides, so....

Much more likely, considering the lack of input from non-European populations in those genetic databases, that the Portguese got around in West Africa as well, so you're sharing some Portuguese DNA with West Africans, not West African DNA with the Portuguese.

...that's what I said? The sailors got around. My Portuguese cousin said that somewhere back in the family line was a distant great-something-something who was likely Black, if family gossip is true, but the records are thin on the ground.
*shrug*

It is what it is.

I think they were saying that it could be your great great great grandfather had kids in Africa and kids in Portugal with different women, and enough sailors did that to skew how the database classifies certain genetic sequences.

So, the genetic sequence(s) identified as West African could actually be Portugese in origin, but are misclassified because not enough West Africans with non-Portugese ancestry have added their DNA to the database for the genetic sequence to be identified as not being indicative of West African ancestry.

Not implausible, but her ancestors were Portuguese nobility, so less likely to marry African commoners--more likely to marry North African or Arab people living in Iberia at the time, but we do know the names of her ancestors traced back to Afonso and Madragana and they were mostly Portuguese and then French.

Interesting.
