Indian Marriage Records

How do i prove my Native American Ancestry?

I just got off the phone with my Uncle Benjamin who was telling me about my Native American Heritage. We’re African American, but he’s been trying to figure out a way to prove that he is Native American as well. Here’s what i have:
-His Father is half Cherokee
-His Grandfather was French Indian
-His Grandmother was full cherokee and was born on an Indian reservation in Alabama

I have there names, but is their a way that i can trace birth records, or marriage liscences to show that we are part Cherokee? Do Native American Reservations keep seperate birth records, and if so, how can i access them. This would mean alot to my uncle, so any help will be greatly appreciated.

They go by birth and census records, it will help greatly if the ancestors were registered with the tribe. To register with the tribe yourself you generally have to be 1/4 blood of that particular tribe. Many tribal councils actually have websites or at least offices you can contact for more information. Search google for “native American ancestry” or even better “Cherokee ancestry Alabama”
