I'm Choctaw. And I'm only 1/32 but I'm on the roll, and so are my kids, who are 1/64. Honestly, I'm not even sure what the significance is of being on the roll. I hope someone has some knowledge and can share!
@JJS:
having a card typically enables you to a vote in tribal elections and a portion of tribal income. Most tribes that have sizable income have pretty strict requirements for eligibility. If you have a card at 1/32, if your tribe does have income, it's probably not a lot. Contact your council for what it might mean for you, they are all different. 4951
