OMG, You've been doing this for 6 yrs. Bless your heart.
Well, my GGF was listed in an 1880 Louisiana Census as Capt. Hart. It says he was born about 1831 in North Carolina, as were his parents.
This is a long shot because I'm starting to believe this man changed his first name to Captain(?). I also think it's a possibility he was shipped from Stagville Plantation to the Cameron Plantation in Alabama. My GGM and their first 4 children were born there. Oldest child born about 1865.
I just wanted to check and see if his move to Alabama wasn't because he was emancipated.
Thanks for all you do!
