There were some African-American Hamilton's in Matewan West Virginia where I am from. I am not but there were some with my father's name (Robert Hamilton. There was also a John and a Patty) I wish I could have been more help. Sally

There was a William Hamilton living in Allegany County, Maryland. He was manumitted prior to the 1850 census as he shows up in that census living in Cumberland. No family listed with him. The manumition papers are filed with the land records at the Allegany County Courthouse. Let me know if you want the address for the courthouse. Connie Beachy
