I had a great uncle by marriage, James Willard Schulz, who went to Montana in the 1880's and lived with the Blackfoot and married a Blackfoot with whom he had a son. He tried to return to white culture after he lost his wife, which is when he married my great aunt. He published a number of books for young readers about his life with the Indians, and he petitioned for Native American voters rights. Fascinating guy, really caught between cultures. When young, he helped a young warrior kidnap his true love and went on war parties. Later in life, he would often disappear for months hunting with tribal friends. My aunt married him during a short stint he did as book editor for the Los Angeles Times, I think it was. Later he married a third wife, much younger. I think my aunt was tired of his wandering ways, but on into her nineties she still spoke of him as if he were the love of her life which he probably was. My late wife (I'm remarried) had a grandfather who was half Crow Indian, and both my late wife and her mother had Native American features, high cheekbones and dark hair.
