From our facility's public access computers, researchers can access digitization partner websites Ancestry.com, Fold3.com, and Familysearch.org. 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 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.**

In addition to the federal naturalization records listed above, the National Archives at Boston holds holds copies of select state, county, and municipal court records for Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont, 1790-1906. An overview of these records can be found in "A Gold Mine of Naturalization Records in New England" by former staff member Walter V. Hickey.
Our facility also holds records of naturalizations in non-federal Connecticut courts, 1790-1974. Included are records of Connecticut Superior Courts, Courts of Common Pleas, District Courts, and some municipal courts. These Connecticut state and municipal court naturalization records are not comprehensive. Some record series contain gaps, and others include only indexes to naturalizations. Please contact us at email@example.com for additional assistance.

Census Records after 1950
Census Records after 1950 are not available through the National Archives. However, you may be able to access certain records for specific legal reasons through the U.S. Census Bureau.

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
- 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 Ancestry.com and Familysearch.org. Please also refer to Boston passenger lists held by the Commonwealth of Massachusetts.
The National Archives at Boston has been working with Family Search to digitize crew lists and related records from our holdings. In most cases, these digitized records have not yet been indexed. However, it is possible to browse the digitized images by port and year on the Family Search site.
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:
- Crew Lists
- Case files of Deceased and Deserted Seamen
- Shipping Articles (which document payments)
- Records of Seamen's Protection (issued for identification)
- Marine Hospital Returns of Seamen (not medical records, documents money withheld for dues)
For an overview of military records held by the National Archives, please see our Research in Military Records page. The National Archives at Boston provides access to digitized military records through National Archives digitization partner websites Ancestry.com and Fold3.com. Included are WWI and WWII draft records, WWII Navy Muster Rolls, and Revolutionary and Civil War military service, pension and bounty land application files. Military service records for WWI and later--including separation documents (DD 214)--are not available online.

Chinese Exclusion Act Case Files for Boston (1911-1955) and Montreal (1900-1952) are a valuable resource for the study of Chinese immigration and Chinese-American travel, trade, and social and family history from the late-19th to mid-20th century. A selection of digitized case files can be found through the National Archives Catalog links above, and new case files will be added as digitization continues.
A typical Chinese Exclusion Act case file contains information such as the subject's name, place and date of birth, physical appearance, occupation, names and relationships of other family members, and family history.
Materials in the files may include:
- certificates of identity and residency
