Royalton is an unincorporated community in northern Amanda Township, Fairfield County, Ohio, United States. Dr. Silas Allen bought and settled the village of Royalton after his time as a surgeon in the Revolutionary War. He then built a house on a crest of a hill fronting a prairie. His purchase consisted of about five hundred acres. Silas's son once said at that time there was not a mark of an ax from Lancaster to his home. The land was soon given to his four sons Whiting, Lemuel, Jedediah and Benjamin Allen. Lemuel and Jedediah gave their ground for a village. In 1810 William Hamilton, surveyed the land that Silas and his sons would soon carve out the village of Royalton, about one mile south-east of Toby Town. The original Plat map of Royalton is still held by one of the residents of the village.
