Where can I find naturalization records?
Answer
Depending on the time period, naturalization records will be at either the Indiana State Archives or the National Archives. Prior to 1906, individuals could be naturalized in any court and so people often chose local county courts where they lived. After 1906, federal law required naturalization records to be submitted to the federal government and most people were naturalized in federal courts. In order to determine when your ancestor may have been naturalized, consult the 1870, 1900, 1910, 1920, and 1930 Censuses. In these years, the census asked questions about naturalization status and in some censuses also asked about the year of naturalization.
