Naturalization Records

Learn about the Pennsylvania State Archives' naturalization holdings.  

Overview

Naturalization is a grant of the full legal rights and privileges of a native-born individual to a non-native foreigner. In England, in the American colonies, and in the United States, naturalizations have been granted by special legislative act or by court proceedings authorized by legislation. The Pennsylvania State Archives maintains various naturalization records from the 18th through the 20th centuries.

County court naturalizations

The Pennsylvania State Archives holds the naturalizations for only a few counties in its collections. Most county court naturalizations are still held by the county, usually with the county Prothonotary or archives.
