Lawrence County, Ohio: History
The earliest European-American settlers, Luke Kelly and his family, and May Keyser, settled at Hanging Rock along the Ohio River in 1796, having migrated from the east. Lawrence County was formed on December 20, 1816, from parts of Gallia and Scioto counties, with the county seat named as Burlington. In 1851, the county seat was moved from Burlington to Ironton. A new courthouse was built at that time. It burned in 1857. The present Lawrence County Courthouse was built in 1908.
Men from Lawrence County served in the Mexican–American War, with at least one having died during that conflict. By 1862, about 3,200 of Lawrence County's men were soldiers in the Union Army in the American Civil War. During World War I, 2,200 of Lawrence County's men served in the armed forces, and 99 died.
