Would anyone have info on Mamie Jackson Blackman. Blackman was her married name. Eldred and Rachel Jackson was her adopted parents name. Her Death Cert states that Mamie was born on 26 Oct 1870 in Putnam Cty, Florida. 1880 CensusAiken Cty, SC states Mamie's relationship with the Jackson's was "other". 1910 census of Aiken Cty, SC states that Mamie's birthplace was FL and also her parents' birthplace was FL. Any help on getting adoption papers or proof of parents would be appreciated.
