The site of the town was fixed under an act of the Missouri General Assembly in 1835, by David Waldo of Lafayette County and Samuel Hink and William Brown, both of Jackson County. In the same year, the first court met for the county, known as Van Buren County. Justices James McClellan and William Savage met in McClellan's residence about three miles (5 km) southeast of Peculiar on September 14, 1835. William Lyon was appointed clerk of the court and county government was organized, including the establishment of Grand River Township.
