Guernsey County is a county located in the U.S. state of Ohio. As of the 2010 census, the population was 40,087. Its county seat is Cambridge, and it is named for the Isle of Guernsey in the English Channel, from which many of the county's early settlers emigrated.
Guernsey County comprises the Cambridge, OH Micropolitan Statistical Area, which is also included in the Columbus-Marion-Zanesville, OH Combined Statistical Area.
Guernsey County, located in the Appalachian foothills, was first formed and organized on 10 March 1810 from portions of Muskingum and Belmont counties, after the Ohio Legislature acted. The first county commissioners were sworn in on 23 April 1810. It lost some land area during the formation of neighboring counties until it reached its present boundaries in 1851, after Buffalo, Beaver, Olive, and Seneca townships were gained by Noble county. After dispute whether the county seat should be established in Cambridge or Washington, it was established in Cambridge after two individuals proposed to donate the land and furnish the public buildings if built in Cambridge.
