The county was formed by the Michigan Legislature in 1840 as Mikenauk County,[5] then renamed Roscommon County in 1843. It was administered by Michilimackinac (Mackinac), Cheboygan, and Midland counties, in succession, prior to the organization of county government in 1875.[4] Roscommon County was named after County Roscommon, Ireland.[1][6]

Geographic features
During prehistoric times, glacial action helped shape the Michigan-area terrain. A large portion of the area is the Grayling outwash plain, which includes sandy ice-disintegration ridges; jack pine barrens, white pine-red pine forest, and northern hardwood forest. Large lakes were created by glacial action.[10]

The county government operates the jail, maintains rural roads, operates the major local courts, records deeds, mortgages, and vital records, administers public health regulations, and participates with the state in the provision of social services. The county board of commissioners controls the budget and has limited authority to make laws or ordinances. In Michigan, most local government functions — police and fire, building and zoning, tax assessment, street maintenance, etc. — are the responsibility of individual cities and townships.
