Yes, we are cousins. My great great grandmother was Sarah (Ollie) Davenport, daughter of John and Sarah. I have only performed a small amount of searching for their parents. I think that William Davenport was John's father, but have not secured any proof, yet. I have found John and Sarah in the 1880 and 1870 censuses, but not in the 1860 census. I haven't done a lot of work on finding their parents, but will be in GA in August. Where have you looked? Have you searched the court records? I am researching three lines of Brown's in GA. Have you researched anything concerning Sarah Brown's family?
