I was checking some information regarding my ancestor, Samuel Hancock of Tallapossa, Al. and ran accross this posting. Don't know what you have found out the last couple of years but the 1880 Federal Census Slave Schedules for Tallapossa County lists 7 unamed slaves owned by Samuel Hancock. One is a "Mulatto" listed as 20years of age. There is a Henry Hancock listed as 40 years of age on the 1880 census. He is listed as mulatto and born in Georgia. Samuel Hancock and family moved to Tallapossa, Al about 1842. He was my ggg grandfather. Could this be the connection you have been looking for? Will be happy to share any information to see the is any connection.
