My whole life I was told I was 1/4 Cherokee. So I traced my heritage and found through family stories and such, that Grandmother Orie I Lisenba was 3/4 Cherokee. Her mothers name was Ada Mandy Harrison. I was told she was full Cherokee and her mother was named Mandy Petty, and her fathers name was Harrison. If anyone has any info on this please help me. It would be greatly appreciated.
