From Richard Crabtree on the Frisco Rails Across Missouri Facebook group: Here we are at Frisco Depot at Sullivan, Missouri. In June 1856, Stephen & Dorcas Sullivan purchased the acreage that was the future site of the original town. On July 25, 1856, when a post office was established in present-day Sullivan, the local postmaster named the place "Mount Helicon". This short-lived name was after an actual mountain in Greece that was the mythical sanctuary of the Muses. In 1859, Stephen Sullivan donated ground for railroad right-of-way and built the depot himself. The railroad named the station “Sullivan” prompting the post office to change to Sullivan.
