Established in September 1843, Murphysboro is the second county seat of Jackson County. Its birth is tied to the disastrous fire that destroyed the courthouse in the first county seat, Brownsville. The fire proved to be the catalyst to move the county seat to a more central location. The name was decided for the new town when William C. Murphy’s name was drawn from a hat containing the names of the three commissioners who chose the new location, a 20-acre (81,000 m2) tract of land donated by Dr. John Logan and Elizabeth Logan. Logan County, Illinois, is named after Dr. Logan.
