The county seat and largest town in the county with a population of 11,733. Located in Theresa, Valley, Clyde, and Custer T. on the James R., at the center of the county. Established upon extension of the Chicago and Northwestern Railroad. Founded by the Western Town Lot Co., and platted June 5, 1880. Named by Marvin Hughitt, President of the Chicago and Northwestern Railroad for the Huron Indians. The name itself is believed to be a corruption of the French word meaning "wild boar," given this tribe of Indians because of their wild and unkempt appearance.
