The naturalization records held by the Westchester County Archives span almost two centuries. These records document the two-step process by which immigrants to the United States first declared their intention to become a citizen (the Declaration) and then, after being a resident of the country for a required period of time, petitioned in court to become a naturalized citizen (the Petition). These records come in various forms and can contain varying types of information (see below).
The Westchester County Archives is engaged in an ongoing effort to create an online index to the naturalization records it holds. The index covers most records through 1928. We are currently indexing our naturalization records through 1955.
Types of Information Available
The naturalization records housed at the Westchester County Archives can be quite useful in performing genealogical research or in studying immigration patterns in a community. At the very least, with the exception of Registration of Admittance records, they provide the name of the individual, the country the person immigrated from, and the date of the declaration or petition. Other information that may be found on naturalization records includes date of birth of the individual, place of birth and occupation, the name of the vessel they traveled on to the United States and the port of entry, and the names of any spouse or children. Naturalizations records created after 1906 contain the most information.
