I am looking for census' and other documentation and information on the following family I found in the 1870 census from Putnam, Ga.

Martha Boudoin, 50, F, B
Peggy Boudoin, 24, F, B
Rosa Boudoin, 12, F, Mu
Frank Boudoin, 10, M, Mu
Sallie Boudoin, 8, F, Mu

I have hardly any information on this family other than Rose/Rosa has 3 children with an unknown White man; Zada(my GGgrandmother), Lavinia/Lavonia and Frank. I know that at some point Rosa and her daughters migrate to Mitchell, Ga where she is shown being married to a Doc Dennis. I also know that Sallie married name is Sallie Stubbs Fudge. I have no other information even though I have tried to look for these people and their neighbors in different census years.
Please help?

Attached is a photo of Sallie
