Jackson/Gordon Family Home Page

I am brand new to researching geneology.I am presently looking for my paternal grandmother's family, particularly her mother.My grandmother was Nancy (Anna) Mae Givens (born in Garland Co., Arkansas 7/15/1894, died in Union Co., AR 1/11/1941, buried in Leola, AR), Married to Marcus Lafayette Jackson (4/23/1892-10-26-1963), parents, Enoch Givens and Martha Couch, other children are Jim, Mary and Matilda.The family oral history is very sketchy on Martha Givens.She was supposed to be full blood Cherokee and somewhere in this picture is a possible adoption.I am not trying to prove indian heritage for any "benefits", simply to solve the family mystery.Any help would be appreciated.
