About Potomac, IL

The town was originally named Marysville after the wives of the two founders, John Smith and Isaac Meneley, who started businesses here circa 1840. On May 13, 1871, a post office was established at the town and was named Potomac, most likely after the Potomac River. The town's name was later changed to conform to this. The town was hit by a tornado in April 1953, injuring a dozen people. Potomac prospered into the late 20th century, with a population peaking at 900 during the 1970 census, due in part to its location along US Route 136, one of the primary East-West highways crossing the state of Illinois.
