Any books which trace the exact origin of black americans to specific parts of Africa?

duh, oviously african americans are from africa, but are there any books out which trace specific physical traits to direct areas in africa. as an african american , i would just like to know. i no way shape or form do i have any connection to africa, i'm a cold blooded new yorker, so were my parents, grands and so on. slavery mixed up many groups and tribes.

if you see a pale skinned red head, green eyed, freckled face kid with a shamrock on his shirt, you don't have to think twice as to what part of europe he's from. have scientists/historians been able to categorize us(african americans) through our traits such as small ears, above average height, sickle cell prone, round head,lol etc?

I don't know of any such books, but most african americans originate from the west african coastal region around the gulf of guinea.
