Trying to trace family "secret" that my gr. grandmother was part Indian.Moved from Tn to OK in 1900 to possibly get land because of connection.She refused to sign papersthat she was part Indian.Had 11 children.Some passed on the "secret", but others did not.After several yrs of trying to connect the dots, yesterday I saw handwritten note in an old relatives files.Judith Kindrick--"she was full blooded Indian".Jackpot!! She was my gr. grandmother's grandmother.But her name is English and her parents and grandparents were English according to my records.But they were from Pittsylvania Co. VA in the early 1700s.There were many tribes there.How can I find out for sure?Some family members refer to my gr. mother as "Black Dutch".This means there was a mixture.Help!
