Regions where most white people have Sub-Saharan African DNA?

[Sikeliot]

I can think of the following...

Madeiran Portuguese
Azorean Portuguese
Afrikaaners
White Caribbean Latinos
White Brazilians
1 in 8 white Americans from Louisiana and South Carolina
1 in 10 white Americans from other states

Any other places this is common?

Whites from Colombia and Venezuela. Not sure if most of them, but is common in many of them to have traces of SSA.

If Coastal Berbers are white at all, one more group.
