This index to naturalization records filed in Chester County covers the years 1798-1935. There are no pre-1798 records, except as noted below.
Names of individuals are spelled as they appear on the records. Names of countries have been standardized, but not modernized. For example, the names of individual German states are used if they appear on the original records.
The naturalization record for an individual may contain a declaration of intention and/or a petition for naturalization. The original records contain information not included in the index. The amount and type of additional information varies. Some records are quite detailed, but many are not.
