Before the American Revolutionary War, persons coming to the colonies from Great Britain were not considered immigrants. However, various passenger lists do exist. It was not until 1819 that the U.S. government required documents on incoming ship passengers. The information contained in passenger lists varied greatly. An excellent index to early records can be found in P. William Filby's series "Passenger and Immigration Lists Index" which can be found in many large research libraries. These indexes cover persons in the 18th and 19th century coming to the U.S. and Canada and refer the researcher to a journal or book in which an individual's name appears in a passenger list. There are other excellent indexes in print and on the Internet.
Naturalization is the process by which an alien becomes a United States' citizen. The process, as well as the methods of record keeping, has varied over the years.
Since September 27, 1906, the U.S. Bureau of Immigration and Naturalization in Washington D.C. has maintained copies of naturalization records. Prior to 1906 the records might be found in an individual county's Court of Common Pleas, Quarter Sessions, or other county courts, the State Supreme Court, and the U.S. Circuit and District Courts.
