A Cherokee Princess? Really?

It's the great grandmother part that gets me... whereas my great grandmother really was Sioux how is it everyone else always says it is greta grandma.... not grandpa or something similar? Anyway I doubt she was a Princess of any kind. I have heard alot of people make that claim though. Of course people make claims all the time.... I knew this one ?woman? who claimed Louis Gossett JR ?spelling? was her cousin or uncle or something... of course this woman lies a lot.
