Igbo ancestry of former Afro American Mayor of Atlanta confirmed 

We proudly maintain that 80% of the ancestors of Afro Americans of the Americas were of Igbo origin. Some came to America directly from Igbo Land. Others had to pass Igbo slave colonies in Angola, Congo, etc. 

The ones that came from Bight of Benin were the Lucumis, the Igbo Aborigines of Ile Ife in today’s Yoruba Land.

Indigenous Lucumi speakers can still be found in Aniocha North, in Igbo Land today, even though the language needs to be boosted.
