For my genealogists
(This is only for finding specific origins of Saltwater Africans you may have in your family tree) To find specific origins and ethnicity such as a kingdom, chiefdom or federation I would suggest researching on Slavevoyages.org from 3-12 years after the birth of the ancestor, you should also look into Akan day names as those were also sometimes translated directly into English, which is then where you would get enslaved Africans with names like Friday. Doing this method I've been able to trace my ancestry back to the Mende Barri/Panga-Kabonde River Chiefdoms of Sierra Leone, and the Arochukwu/Ohatia/Bende which is also known as Igboland and the Kingdom of Kongo.
