My wife's great-great-grandmother was full-blood Cherokee. It had been HER responsibility to register the family not long after the turn of the 20th Century here in Oklahoma but she refused to do so. It seems that being "Indian" in those days wasn't something of which to be "proud." As a consequence, none of my wife's family is on the rolls of the Cherokee nation. Both her grandmother and her father are now deceased so there's no chance that it'll ever happen now. As a consequence, my wife never mentions her Cherokee heritage to anyone.
