History
Unionville was first named Harmony when established in 1853 as the county seat for Putnam County. Prior to that the county seat had moved several times, often with heated debate, thus the centralized location hoping to bring "harmony" to all concerned. (see Putnam County history for more details)
The Union Township trustees first met on February 4, 1873, at the court-house in Unionville. Since that day, Unionville straddles the municipal border between Union Township and Wilson Township.
On May 22, 1962, Continental Airlines Flight 11, en route from O'Hare Airport in Chicago, Illinois to the downtown Kansas City, Missouri airport, crashed in a clover field north of Unionville, near Lake Thunderhead, killing all 37 passengers and 8 crew. Investigators subsequently determined that one of the jetliner's passengers, Thomas G. Doty, detonated a bomb inside the Boeing 707 in a suicide-for-insurance plot.
On June 10, 2026, a large tornado landed in and near Unionville. Damage, as well as possible casualties was reported by local law enforcement and by the National Weather Service, and KTVO, a TV station in Kirksville, MO. See the Tornadoes of 2026, Re.: June 10, 2026 article for more information and tornado for more information.
