In Clark County, the earliest naturalization records were listed under the Clerk of Courts, Common Pleas Court. Between 1820-1854, these records are found scattered throughout the minutes of the Common Pleas Court, and then are found in the District Court records from 1852-1884. Naturalizations from 1856-1877 are in the Clerk of Courts records.
As early as 1861, naturalizations were handled through the Probate Court. This continued until 1906, when naturalizations records came under the jurisdiction of the federal government.
