“Bull Head was born in 1863 and was named for a relative who was head chief of the Peigan tribe when the North-West Mounted Police came west in 1874. He lived at first with the South Peigans in Montana, then was taken as a child to the Blood Reserve at Brocket, where his name was changed to Bull Head, but he was popularly known as Eagle Young Man. A good friend of de Grandmaison, he was a fun-loving man, a practical joker well liked by everyone who knew him.”
