I found a Wikipedia article that lays out the required ancestry for tribal membership for various tribes. (
https://en.wikipedia.org/wiki/Blood_quantum_laws) The percentage varies from 5/8 Ute ancestry to minimal amounts for other tribes. For most of the Five Civilized Tribes, it looks like the only requirement is descent from someone on the Dawes Rolls.
In another article, I discovered a federal document issued to individuals named a "Certificate of Degree of Indian Blood". Is it just me, or does this seem a little creepy?
