The story

How Winnett came to be

From Wikipedia’s history of Winnett.

Read it all →

Winnett was named for Walter John Winnett (1860–1943), who was born at the Queen's Hotel in Toronto, Ontario, Canada. Winnett ran away from home as a boy, seeking adventure in "Indian country." His excellent marksmanship abilities helped him get jobs with outfits who were always looking for someone who could keep them in fresh meat. When he was captured by Sioux Indians and later adopted into the tribe, he was given the name Eagle Eyes because of his remarkable shooting skills.
