From Where in Africa Did African Americans Come?
This information comes from P.D. Curtin's book, "Atlantic Slave Trade" p. 221. Obviously, this is not the only version available, but Curtin is a heavyweight on the subject (along with W.E.B. DuBois, R.R. Kuczynski, E. Donnan, Davies, H.S. Klein, etc) and I like the way the data is presented:
PROJECTED EXPORTS OF THAT PORTION OF THE FRENCH AND ENGLISH SLAVE TRADE HAVING IDENTIFIABLE REGION OF COAST ORIGIN IN AFRICA, 1711-1810.
Senegambia (Senegal-Gambia) * 5.8%
Sierra Leone 3.4%
Windward Coast (Ivory Coast) * 12.1%
Gold Coast (Ghana) * 14.4%
Bight of Benin (Nigeria) * 14.5
Bight of Biafra (Nigeria) * 25.1%
Central and Southeast Africa (Cameroon-
N. Angola) * 24.7%
* The countries in parentheses
are rough approximations to help
you find the location on a modern map.
Now I will try to relate the above regions to selected ethnic groups. I've collected this data from a variety of sources, and I can't vouch for all of them. The central question for me is always, "Were these people called by that name during that time in that place?" I don't know how to show the nomadic and semi-nomadic groups, but I included several below anyway.
SENEGAMBIA: Wolof, Mandingo, Malinke, Bambara, Papel, Limba, Bola, Balante, Serer, Fula, Tucolor
SIERRA LEONE: Temne, Mende, Kisi, Goree, Kru.
WINDWARD COAST (including Liberia): Baoule, Vai, De, Gola (Gullah), Bassa, Grebo.
GOLD COAST: Ewe, Ga, Fante, Ashante, Twi, Brong
BIGHT OF BENIN & BIGHT OF BIAFRA combined: Yoruba, Nupe, Benin, Dahomean (Fon), Edo-Bini, Allada, Efik, Lbibio, Ljaw, Lbani, Lgbo (Calabar)
CENTRAL & SOUTHEAST AFRICA: BaKongo, MaLimbo, Ndungo, BaMbo, BaLimbe, BaDongo, Luba, Loanga, Ovimbundu, Cabinda, Pembe, Imbangala, Mbundu, BaNdulunda
Other possible groups that maybe should be included as a "Ancestral group" of African Americans, and in what region:
Fulani, Tuareg, Dialonke, Massina, Dogon, Songhay, Jekri, Jukun, Domaa, Tallensi, Mossi, Nzima, Akwamu, Egba, Fang, and Ge.
