Descendents of Larkin and Annie Carter (Walton County, Ga)

Maurice Arnold
I am researching my family history in Walton County, Ga. My 3rd great grand parents were Larkin (b.1830) and Annie/Ann (b.1835) Carter. They had 10 children: Gage, Elizer, Mary, Lucy/Lucie, Henry, Isaac, Charlie, Sis, Bro, and Howard. My great great grandmother Lucy/Lucie married Edward White in 1894. My great grandmother Allene Brown (White) was their first born with 12 children to follow.
I know Larkin and Annie were both born into slavery but I have no info on their parents not their slave owners which I know for sure were Carters. I also can't find in info own my great grandfather Edward White.
Please help.
