History

Formed in 1810 from Muskingum County and Tuscarawas County

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

Coshocton County was created from Muskingum and Tuscarawas counties in 1810, though it remained unorganized and attached to Muskingum for administrative and judicial purposes. The county became fully organized on April 1, 1811, when it was detached from Muskingum. In 1824, Holmes County was created from Coshocton's territory; Holmes remained partially attached to Coshocton until becoming fully organized in 1825.
