In Mercer County, the earliest records of naturalization are found under the Clerk of Courts. The first records are found scattered throughout the Minutes of the Common Pleas Court and date from 1814 to 1852. A series of unbound declarations, dated 1838-1839, and a volume of declarations and final papers, dated 1852-1860, complete the set of records issued by the Clear of Courts.
In the second half of the 19th century, naturalization records were issued by the Probate Court. This practice continued until 1906, when the process of naturalization came under federal supervision.
