As an aside ...
I do not know about a "Family History Centre" for "African America" ...
There is a 'Group' in this "Community.FamilySearch" Forum being:
African American Genealogy Research
That 'Group' is "Public", anyone can "Join".
I am "Tagging" this (General) 'Question' of yours, to the 'Group' being "African American Genealogy Research", in this "Community.FamilySearch" Forum; so that, the members of that group can answer/assist you.
I hope this may help.
@Africa Genealogy Research
what center precisely are you referring to?
or is it merely that you are looking for African American Resources wherever they are?
