Early naturalizations in Logan County, Ohio, were handled by the Clerk of Courts, and appear in the Minute Books of the Common Pleas Court, 1818-1854. From 1860-1906, Logan County's Probate Court took over the granting of citizenship, and naturalizations appear in Probate Court records.
This practice continued until 1906, when the process of naturalization came under federal supervision.
