Dad's side of the family is basically all native american or french fur trader; they liked to mix a lot back in the day I think

One more generation removed I also have a Chippewa ancestor, although we don't identify as strongly with them.
In addition to my grandparents receiving res money, my dad's sister also receives it (both are from same parents.) My dad does not, although I don't think he has pursued it too rigorously. I'm sure I could get proof of my grandfather on the tribal registry if it was needed. My dad also has some kind of tribal ancestor certification letter himself, and I'm sure I could get a copy of that.
I have never bothered to get any kind of 'official' documentation of this for myself though, as my family has since moved away from the Dakotas. I'm not sure exactly how I would go about dealing with the tribal council if I needed something for myself, although I would bet I can get the same kind of tribal ancestor letter my dad did.
I can honestly say that my heritage has had a big effect on my life and such, but I honestly have no idea how this whole URM thing works. What kind of documentation would I personally need to have any kind of meaningful impact on my application this coming app season? Is any of this even significant enough to be have an appreciable effect, since I am obviously not the tribal registry myself?
I'd particularly like to hear from any NAs, since I hear it is a little different process than if you are black or PR.. if there are any of you guys on this board, although all advice is appreciated
