Dear Ms. Woodhouse,
Thank you for posting your request on History Hub!
Prior to September 27, 1906, any "court of record" (municipal, county, state, or Federal) could grant United States citizenship. Often petitioners went to the court most geographically convenient for them. As a general rule, the National Archives does not have naturalization records created in state or local courts. However, a few indexes and records have been donated to the National Archives from counties, states, and local courts. We suggest that you contact National Archives at Chicago (RM-CH) via email at firstname.lastname@example.org to determine if records from lower courts are available. Please include the name of the petitioner (including known variants); date of birth; approximate date of entry to the US; approximate date of naturalization; where the individual was residing at the time of naturalization (city/county/state); and country of origin.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RM-CH. We apologize for this inconvenience and appreciate your understanding and patience.
If the records are not available, we suggest that you search the Wisconsin, County Naturalization Records, 1807-1992 or request a search for the naturalization records from the Wisconsin Historical Society.
We hope this is helpful. Best of luck with your family research!
