Yeah... blue eyes and blond hair, definitely an Indian trait.
That alone is not a disqualifier, just an external expression of mixed genetic traits.
One of my wife's uncles and one of the grand kids have blonde hair and blue eyes--all are 1/4 or more Chippewa. Others have red hair, but brown eyes, still Chippewa.
I am red haired and blue eyed. I worked for about a year for the Mashantucket Pequot tribe here in Connecticut. The first tribal member I met could have passed for my brother or at least a cousin. He was red haired and blue eyed. The tribe contained all sorts of phenotypes; lots of blondes, red heads, brunettes, whites, blacks even an Indian (as in Bangalore) with no explanation or excuses offered.
I cannot rationally argue with anyone who claims that the Mashantucket Pequot Tribal Nation (as it’s officially known) is a total fraud and a fiction. It does, however, allow a bunch of wannabes to run a casino.
