Ethan Bennett Farnum (November 10, 1826 in Cheshire, Massachusetts – after 1880) was one of the first residents of Deadwood (then in the Dakota Territory), who was not a miner or prospector; he was the owner of a general store. Farnum was married to Mary Farnum, with three children: Sylvia, age 16, Edward, age 12, and Lyde, age 2 when he arrived in Deadwood. He was the first mayor of the town of Deadwood.
