History

Formed in 1817 from Guernsey County, Muskingum County and Washington County

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

Morgan County was created on December 29, 1817, from parts of Guernsey, Muskingum, and Washington counties. The county was named after Daniel Morgan. Initially not fully organized, Morgan became fully operational on March 1, 1819, after being detached from the three parent counties. The county's boundaries changed multiple times, losing territory to Monroe County in 1819 and gaining territory from Athens, Washington, and Noble counties through 1851.

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