Ferron was originally populated by Mormon settlers in 1877. Three families responded to a call from the LDS Church asking to settle in the Castle Valley. They started on November 15, 1877 and arrived about 21 days later. The group spent time creating dugouts and later made their living in farming. Although settled in late 1877 the town had received its name sometime in the late 1860s to early 1870s when a government surveyor was sent under the homestead act to survey the area. The surveyor's name was Augustus D Ferron and, as the tale goes, the agreed to name the creek they camped by Ferron's Creek if he would agree to a "dunking" in the creek. He did so and the creek was then known as Ferron's Creek. Later when the town was settled the "s" was dropped from the name and the creek and town became known as "Ferron".
