Index Status: Most of the naturalization records dated between 1808 and 1927 held by the Archives have been indexed. However, some records have only recently been discovered to have not yet been indexed, including several books primarily covering the city of Yonkers. Efforts are currently being made to index those records through 1927. In addition, Series 14, Rejected Petitions, have not yet been included in the index. If you suspect that a naturalization record is held by the Westchester County Archives but you are unable to locate the name in this online index, you can submit a Custom Research Request to locate the information.
Note: It is recommended that the index be scrolled through, rather than using the "Find" function of your browser. See our online indexes searching suggestions for more information.
