History

Formed in 1843 from Adair County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Putnam County was created from non-county areas and initially attached to Adair County for civil and military purposes. In 1845, the county was fully organized and detached from Adair. The county gained all territory of Dodge County in 1853 after Dodge was eliminated.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries.
