History
Formed in 1806 from Trumbull County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Geauga County was created from Trumbull County in 1806. The county's boundaries changed significantly in its early years as neighboring counties were formed and organized, with parts of Ashtabula, Cuyahoga, Huron, and Lake counties all created from or initially attached to Geauga between 1808 and 1840. In 1827, Geauga's limits were extended to the northern boundary of Ohio over the waters of Lake Erie.
