History of Mills County
The future county's first permanent settlement was Rushville, founded in 1846 by persecuted members of the Church of Jesus Christ of Latter-day Saints as they were being driven out of Nauvoo, Illinois. This is not to be confused with the state's present-day Rushville in Jasper County. A nearby settlement, also founded by the Mormon settlers, was called Coonsville after Dr. Liberius Coons, one of the first arrivals. That settlement continued after the Mormons moved on; its name was changed to Glenwood in 1853. In Glenwood, the first courthouse was a small frame building which served until 1857. It was replaced by a two-story building, which was enlarged in the 1900s and received a clock tower in 1910. In 1959 this building was replaced with the present building, dedicated on August 29, 1959.
