That’s interesting about the missing teeth. I, on the other hand, have a son who had 6 wisdom teeth. When we went to get them pulled they wanted to know if he had any Eskimo blood. His father had a great grandmother who was Canadian Cree Indian. I suppose the Crees could have wandered far enough north to encounter some Eskimos.
