I research a HILL line from when they arrived from eastward into NY at 18th century Dutchess County. Frank Doherty's "Settlers of Beekman Patent" footnotes that George Hill may have married a wife from Sharon CT surname Africa. My access to resources is geographically limited but I find no Africa family in this county during the colonial & Revolution period. Got Clues?
There is a female Alla Africa & some daughters at Greenwich, Fairfield, CT on 1820 census but that's 50+ years cold & useless for me. 1810 has some MD VA & PA.
I don't find an Africa family discussed either in the John & Richard Polhemus book "Up On Preston Mountain". I didn't find a surname message board for Africa.
