The story

from WikipediaRead it all ↗

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.
