I have no records, photos, or information other than stories to prove that I am a member of the Cherokee Nation Tribe. Where do I begin? My great, great, great grandmother was a full blood Cherokee and married (for lack of better words) a complete dick from Ireland. He never allowed her to register with the tribe so even if I could prove my linage to her I'm assuming I would have to find her mother and father as well. I have no experience in genealogy so any input is extremely appreciated.
