Digitized Records and Databases

From our facility's public access computers, researchers can access digitization partner websites,, and These sites provide access to digital copies of a wide range of records, including the US Federal Census (1790-1950), Indian Census Rolls (1885-1940), naturalization records, passenger lists, death indexes, WWI and WWII draft cards, military pension records, and much more. Many of these records are also being added to the National Archives Catalog. For a listing of NARA microfilm and original records available on partner websites, please see Microfilm Publications and Original Records Digitized by our Digitization Partners. Copies of select genealogy records can also be ordered through the  National Archives online order system .

Naturalization Records

Naturalization is the process by which an alien becomes an American citizen. Depending on the year of issue, these records can provide researchers with information such as a person's birth date and location, occupation, immigration year, marital status and spouse's information, witnesses' names and addresses, and more. As a general rule, pre-1906 naturalization records contain less detailed information about the applicant.

Before September 27, 1906, any "court of record" (municipal, county, state, or federal) could grant U.S. citizenship. After 1906, the courts forwarded copies of naturalization records to the U.S. Immigration and Naturalization Service (INS). U.S. Citizenship and Immigration Services (USCIS), the successor federal agency to INS, maintains a master file of all naturalization proceedings occurring after September 26, 1906.  Most inquiries about post-1991 naturalization records must be directed to USCIS, as the National Archives generally has such records only through 1991. More information on the naturalization process can be found on the National Archives' main Naturalization Records page.

**Please note: the National Archives does not hold copies of naturalization certificates. Naturalization certificates issued 1906-1956 can be ordered through the USCIS Genealogy Program.**

Passenger Arrival Lists

In an effort to protect immigrants and encourage travel to the United States, the Federal Government required passenger lists beginning in 1820. Since then, over 55 million people have immigrated to the U.S. These immigration records can provide genealogical information including:

  • a person's nationality, place of birth
  • ship name and date of entry to the United States
  • age, height, eye and hair color
  • profession
  • place of last residence
  • name and address of relatives they are joining in the U.S.
  • amount of money they are carrying, etc.

Passenger lists for major ports throughout the United States have been digitized and can be searched through our digitization partner websites and Please also refer to Boston passenger lists held by the Commonwealth of Massachusetts.

Customs Records Related to Seamen

Digitized crew lists and related records for a number of ports in Connecticut, Maine, Massachusetts and Rhode Island are now available in the National Archives Catalog.

American seamen from New England are documented in a variety of U.S. Customs Service records. Researchers will need to know what ports individual seamen may have shipped out of in order to effectively use these records. To locate crew lists it is usually necessary to know the vessel name and port. Crew lists and related documents are available for various New England ports, 1789-ca. 1950. Please inquire about using these records before visiting the National Archives at Boston in person, since records do not exist for every New England port in all time periods.

Information may include:

  • place of birth
  • town of residence
  • physical description
  • names of relatives

Specific types of records include:
