We have common ancestry. My grandfather was the younger brother of Lettie. His name was Robert Virgil Petty. He didn't say anything about Cherokee ancestry. I have found in one other instance that an ancestor was supposed to be Cherokee, but it turned out that they were born in Cherokee county or moved into newly released Cherokee lands. I will be happy to share what I have on the entire family. I am really interested in the Petty half sisters Marie and Christine. Do you know who their mother was?
