Delaware County

The story

Local history for this place is being researched county by county outward from Franklin County; here is what the records say.

Delaware County was created by the Ohio General Assembly on February 10, 1808, out of Franklin County, and named, like its seat, for the Lenape (Delaware) people. The seat, Delaware, was platted that same year by Moses Byxbe and Henry Baldwin on the west bank of the Olentangy River, on the ground of a former Mingo village, Pluggy's Town, and around a sulphur spring that grew into a failed resort hotel before becoming, in 1842-44, the seat of Ohio Wesleyan University. The county gave the country a president, Rutherford B. Hayes, born in Delaware in 1822, and gave up more than half its original territory to the later counties of Union, Marion and Morrow. Four twentieth-century reservoirs - O'Shaughnessy, Delaware Lake, Hoover and Alum Creek - now cover parts of the county's river valleys, the last of them drowning the Underground Railroad settlement of Africa along with a run of Adena burial mounds. Since 1990 Delaware County has been one of Ohio's fastest-growing counties, its population more than doubling as Columbus's northern suburbs - Powell, Lewis Center, Orange Township - filled in what were, within living memory, farm townships.
