Finding out where 19th and early 20th century ancestors naturalized can be difficult, indeed, given that:
1. They could naturalize at any court with a full-time clerk and official seal
2. The steps of the naturalization process could occur at different courts in different states
This record collection in Ancestry Library Edition (Ancestry LE) may help solve some naturalization questions:
New York, Passenger and Crew Lists (including Castle Garden and Ellis Island), 1820-1957
This collection is an index to passenger lists of ships arriving from foreign ports at the port of New York during the period 1820-1957. Lists can be crew lists, lists of American citizens returning from overseas, or lists of foreign nationals. Search results include a link to an image of the passenger list, and sometimes include a link to a photo/illustration of the ship in question.
Castle Garden served as a New York processing station for immigrants from 1855 to 1890, while Ellis Island served as a New York processing station from 1892 to 1954. This record collection indexes both Castle Garden and Ellis Island passenger lists, plus lists from several other New York processing stations that were also sometimes utilized.
Information provided in search abstracts includes:
Port of arrival
Port of departure
Now, the search abstracts include only part of the information that may be available on the actual passenger lists. Some lists in fact asked naturalized American citizens for the location of the court and the date when the naturalized citizen filed Final Papers. A number of test searches revealed that recent passenger lists (1930 and later) appear more likely to request naturalization information.
