Custer County was named for General George Armstrong Custer, controversial Civil War officer and Indian fighter. Custer County includes the towns of Broken Bow and Sargent. It also houses the villages of Anselmo, Ansley, Arnold, Berwyn, Callaway, Comstock, Mason City, Merna, and Oconto. 4th highest number of cars in 1922? Every single person in Custer County in 1922 must have had 2 cars, that’s the only thing I can think of.
