The origins of the Africans brought here is irrelevant when you factor in the domestic slave south.
Most black Americans from the deep south(Louisiana, Bama, Sip) have roots in the upper south(Carolinas, Virginias, Kentucky).
Even less relevant when you factor in basically every black American in the west, Midwest, and east coast have roots in the south, even if they have slavery roots from outside of the south. It's all mixed in at this point.
That was my entire point.
We're too intermixed with other groups to pinpoint exact origins.
Here's the thing tho..
That doesn't apply to everybody.
Geechi populations deep in the woods from say Sc to central Fl are definitely exceptions to that rule.
Blacks from Ms & La too, that's why I highlighted them - blacks from the southern Gulf literally have more ancestrally in common with carribeans than they do blacks from other regions of the US.
Do u know how Louisiana became a slave colony? Or where the French got their slaves from to populate the place for that matter?
Many didn't even come directly from the continent, (Africa).
Basically southern blacks are genetically more homogeneous than non southern blacks, (erase culture from your mind - I'm talking ancestry).
Which makes sense because groups outside the south were the one's who migrated.
You do realize the Gulf states are called that for a reason right? They have ports.Purchasing slaves from out of colony auctions did happen but not how you're describing it.
Southern blacks who've lived in the same areas since slavery buck that trend.That's why it's easier for us to pinpoint specific groups we're related to directly from Africa.
(Only the ones interested in stuff like ancestral genealogy).
We the same, but we not the same.
We don't all have the same family stories.
Some of our families have been here since before the US was the US.
Some of our families were late comers (outlawed slave trade)
This logic also applies to the rest of the black diaspora so don't think I'm just singling us out.
Some of us are lucky enough to have cultural continuity/retention like this
