Cook Count naturalization records are available from 1871 forward. (Earlier records were destroyed by the Chicago Fire.) They were created by five courts: Criminal, Circuit, Superior, County, and District. Records from the first four are held by the Cook County Circuit Court Archives. Records from the District Court are held by the National Archives at Chicago.
The earliest Cook County naturalization records provide little, if any, genealogical information. However, if the declaration was filed in another location, the file might include helpful details.
Records from 1904-late 1906 can include birth date and town, departure and arrival information, and occupation.
Records from October 1906 forward generally include birth dates and places for the applicant's wife and children and a physical description of the applicant. For more information, please see the Cook County Circuit Court Archives' Important Information about Naturalization Searches page.
