 Thorpe's parents were both of mixed-race ancestry. His father, Hiram Thorpe, had an Irish father and a Sac and Fox Indian mother. His mother, Charlotte Vieux, had a French father and a Potawatomi mother, a descendant of Chief Louis Vieux. He was raised as a Sac and Fox, and his native name, Wa-Tho-Huk, translated as "path lit by great flash of lightning" or, more simply, "Bright Path". As was the custom for Sac and Fox, he was named for something occurring around the time of his birth, in this case the light brightening the path to the cabin where he was born. Thorpe's parents were both Roman Catholic, a faith which Thorpe observed throughout his adult life.
