Dover was a former post office in the township that operated from May 28, 1836, until October 26, 1841. Peter Truitt, from Slatter Neck, Sussex County, Delaware, settled on 80 acres (320,000 m2) near the center of the township in 1831. He operated a tavern on the old Chicago Road between Chicago and Detroit (now US 12), known as the "White Oak Tavern" because of an immense oak tree near the house. A second post office named Truitt's operated July 26, 1897, until June 29, 1901, at a station on the Cleveland, Cincinnati, Chicago and St. Louis Railway Grocer James W. Smith as postmaster.
