my name is aimee colvin and I have been trying to find colvins in the slave data and census but I have come to a dead end. I found information on my grandfather but he was born 30 years after slavery in 1894.In Alabama.butI cant seem to find any record of him in the census. I'Ve been told by my father that my great-grand mother was a full blooded Indian.I dont know what race my great-granfather was could it be possible that my great granfather was a free man. If so, how do I began to search for him.
