My husband's gg grandmother was Mary Ann Blackston(e) born 01 Mar 1831 most likely in Columbia Co or Richmond Co, Georgia.She married John Lewis.
I can not figure out who Mary's parents were.
I do know that John Lewis' brother, Littleberry Lewis, married Francis Blackstone.Francis was born abt. 1796 in Columbia Co, GA.Her parents were James Blackstone (born abt. 1771 in Columbia Co, GA) and Frances Ree.
Francis Blackstone was quite a bit older than my Mary Ann but I am sure they are related in some way.(Mary Ann's husband, John Lewis, was 30 years her senior.That is why his brother's wife was so much older than Mary Ann).
I found a couple of Blackstone's in the Richmond Co census that are possible parents for my Mary Ann.
Zephamiah Blackstone and Argyle Blackstone.Both of these men had a female child about the right age to be Mary Ann in the 1840 census.
Half the family used Blackston and the other half used Blackstone.It makes my life very stressful :)
