The Immigration Database provides insight into the growth of the area's population through immigration from other lands. Understanding the roots of our diverse population and their cultures provides a broader understanding of our community's background. Naturalization records for Vanderburgh and Warrick Counties from 1850 through 1920 have been indexed in a searchable database which provides access to the records in alphabetical format. The database is even more valuable since all Immigration and Naturalization records currently held at the county courthouses will eventually be moved to Indianapolis for preservation and be difficult for researchers to access.
