History

Formed in 1816 from Athens County, Gallia County, Ross County and Scioto County

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

Jackson County was created March 1, 1816, from Athens, Gallia, Ross, and Scioto counties. The county gained area from Ross in 1818, then lost a small area to Ross in 1839 and exchanged territory with Pike in 1843. In 1850, Jackson gained from Gallia and lost area to the creation of Vinton County.
