Dates of naturalizations are from October 28, 1856 to October 26, 1906. The records are extremely sparse due to courthouse fires. Some Restored Naturalizations can be found in Marriage Record volumes C8 and C11. Select the appropriate category below once a volume and page number is found after searching the Naturalization Index Books. However, the Naturalization Index is a more thorough record than the documents on file with the court. Volume numbers are from 1 to 48 but not all 48 volumes exist. The missing volumes and volumes 49 and up were destroyed in courthouse fires.
