Immigration and Naturalization Records Research

Naturalization is the procedure of awarding citizenship to foreign-born residents. Naturalization documents are an crucial resource of details about an immigrant’s place of origin, his or her foreign and Americanized names, residence, and also day of arrival.

Immigrants to the United States haven't ever been required to fill out an application for citizenship. Individuals that applied, quite a few just didn't complete the requirements for citizenship. Facts that an immigrant achieved citizenship prerequisites could be uncovered in censuses, court minutes, homestead records, passports, voting registers, and military papers. Even when an immigrant ancestor failed to complete the process and turn into a citizen, he / she could possibly have filed a declaration. These kind of declarations might be very useful.

Different sorts of records were created through the naturalization process, among them declarations of intention, petitions for naturalization, oaths of allegiance and certificates of naturalization and citizenship. Each and every record can give details about a person, for instance age, residence, country or city of origin, ethnic background, the date and port of arrival, the name of the ship, names of spouse and children along with their birth dates and places, and former residences or current address.

The majority of the immigrants coming to New Jersey by boat in the 1800s and 1900s went through either Philadelphia or New York. However, some came straight to New Jersey. Passenger lists for those ships can be found at the National Archives-Northeast Region. Those included:

  • Perth Amboy (1801-37, With Gaps)
  • Bridgetown and Cape May, 1828
  • Little Egg Harbor, 1831
