Unionville Putnam County, organized in 1845, apparently has had six different courthouses. While the first county seat and first courthouse were in Putnamville, county officials moved the county seat several times before permanently establishing it a Unionville.
Little information exists about the first three courthouses in the county.
At that time, county jurisdiction included land extending nine miles north into Iowa. Robert Cochran superintended Guffey's work. Next, the county seat moved to either Calhoun or Winchester. A court order called for a move to Calhoun in August 1847, according to Goodspeed's 1888 History . However, the order may never have been fulfilled.
