The farthest back I have in our family is a James A. Gammage born in 1832 in Georgia. I don't have a county, siblings, etc on him yet. He married a Mary E. May in 1859. I know they ended up in Alabama because their son Charles was born in Covington County, Alabama. I haven't tried to search for James yet because of not having the county he came from. Have you tried a census record for 1840 in Fulton County?
