The naturalization and citizenship records of Indiana offer a window into the state’s immigrant history, particularly during the industrial boom of the late 19th and early 20th centuries. Prior to 1906, naturalizations were conducted in various local courts—common pleas, circuit, and superior—with records varying in content and completeness. After 1906, U.S. District Courts provided standardized records, including petitions and declarations rich with biographical details. Indiana’s records reflect the diverse origins of its immigrants—Germans, Irish, Italians, and Eastern Europeans among them. While federal passport applications reference Indiana residents, naturalization records remain the primary genealogical source. These documents help reconstruct family migration stories and provide insight into Indiana’s role in the American immigrant experience.
