Researching Your 1812 Impressed Seamen

Uncovering data and documents of your seafaring ancestor can be challenging. Seamen and privateers' commitment to life on the seas rarely produced land deeds, etched tombstones, family photos, or other favorite genealogical treasures. Research is further complicated by Britain's impressing of American sailors and privateers into the Royal Navy. Perhaps your mariner was one of the 10,000 impressed seamen who served under the enemy's flag between 1802 and 1812.

Impressing seamen became a common practice during the Napoleonic Wars by both the British colonial rule and the French. In 1757 British soldiers forcibly corralled eight hundred tradesmen and sailors from New York taverns and popular gathering places, for the purpose of forced military service.

After the Revolutionary War, the British continued seizing U.S. flagged vessels and impressing their crew, making protection of U.S. Seamen on American ships a contributing factor of the War of 1812. Many historians argue that the Revolutionary War began in Massachusetts in 1775 but did not actually end until 1815 with the signing of the Treaty of Ghent.

Genealogical Seamen Records

To protect American crew and mariners, Seaman Protection Certificates (SPCs) were issued. While impressing seamen ceased after 1815, SPCs were issued as through the Civil War and even as late as the World War 1 era (1918-1919). (See: Records of the Bureau of Marine Inspection and Navigation. Seamen were also enumerated on the 1930 Merchant Seamen, "Crews of Vessels.," available on and NARA microfilm M1932.

African American & SPCs

Many African Americans served during the War of 1812 on both land and sea. Free coloreds, runaways, and ex-slaves served on desegregated vessels while holding Seaman Protection Certificates and were impressed along with their shipmates. In 1838, the well-known runaway, orator, and abolitionist Frederick Douglas donned a sailor uniform and borrowed an SPC to aid in his escape from slavery.

Genealogical Finds

The details provided by sailors on SPC applications can prove to be a treasure chest for family historians. These applications were an attempt to clearly identify American citizens at sea. In addition to occupation, place of birth, and physical descriptions of scars and marks, the genealogist may uncover home address and family information from the SPC application. Family members often served as witnesses and signed a sworn statement, identifying themselves as a "wife" or "mother."

Researchers should not accept the myth that seamen were limited to those living in Atlantic seaboard states. Men from age eleven to seventy seven years old represented all the states and territories. Missouri seaman John Finn, was 14 years old, from Hermann, Mo. and he worked out of the Port of Philadelphia.


To have sea protection from the United States proof of citizenship was needed. Bernard Tobin's application states, "Do hereby declare that I am a Seaman and an affiliated Citizen of the United States, having been born in the Town of St. Johns Newfoundland and have declared my Intention of becoming a citizen of the United States in the Circuit Court holden in Philadelphia on the 27th of December 1856 a certificate whereof I herewith present."

While researching African American ancestry, you may uncover a slave master's name, emancipation information, and country or residence of origin. Samuel Ridley, an ex-slave from Long Island, NY informed the in-taker that he "was manumitted in the year 1792 by Stephen..." Samuel's application goes on to tell us that he served nine years in Philadelphia for his freedom.

W. Jeffery Bolster documented Letters by African American Sailors, 1799-1814 recounting 14 letters written by eleven impressed African American seamen into the Royal Navy.

Five Places to Begin Your Search

Original mariner issued certificates are rarely located, but SPC applications for several ports, newspaper articles, application abstracts, and government reports are available to researchers. The family researcher will find birth information, next of kin, place of origin, and naturalization information on these applications. It is possible your impressed ancestor was captured and his original (or second or third) certificate was confiscated. So it is not uncommon to find several applications for one seaman. Here are a few places to begin your search:

    1. National Archive Resources. Impressed seamen information from 1793-1814 may be located at the National Archives:
      • Registers of Applications for the Release of Impressed Seamen. Microfilm M2025.
      • Miscellaneous Lists and Papers Regarding Impressed Seamen, 1796-1814 can be located on microfilm M1839:
      • Proofs of Citizenship Used to Apply for Seamen's Protection Certificates at the Ports of Bath, Maine, 1833, 1836, 1839-50, 1853-65, 1867-68; and at Portsmouth, New Hampshire, 1857-58. NARA microfilm M1825.
      • Proofs of Citizenship Used To Apply For Seamen's Protection Certificates for the Port of New Orleans, Louisiana, 1800, 1802, 1804-1812, 1814-1816, 1818-1819, 1821, 1850-1851, 1855-1857 NARA microfilm publication M1826.
      • Proofs of Citizenship Used to Apply for Seamen's Certificates for the Port of Philadelphia, Pennsylvania, 1792-1861. NARA microfilm M1880.

    1. The applications for U.S. Seamen's Protection Certificates from 1792-1868 have been indexed and digitized at The collection of Port of Philadelphia certificates is the most extensive, but other collections of original SPCs were destroyed after being indexed and abstracted by the Works Protection Administration (WPA).

    1. The Indexes to Seamen's Protection Certificate Applications and Proofs of Citizenship on includes approximately 50,000 seamen names who filed for Seamen Protection Certificates between 1796-1861. Thirteen East Coast and Gulf of Mexico port applications are included in the index.

    1. Naval History and Heritage Command. Commissioned and warrant officers of the US Navy and Marine Corps from the close of the War of 1812 are listed and indexed on the Naval History and Heritage Command website. Researchers may uncover promotions earned during the war with Great Britain

    1. State Archives, Libraries and Museums. Seaman Protection Certificates may be found in various state repositories. Be sure to check your State Archives, state genealogical societies and local maritime and war museums. The Rhode Island Historical Society published the Register of Seamen's Protection Certificates from the Providence Rhode Island Customs District from 1796-1870. These have been digitized on

      The National Archives in Waltham Massachusetts holds the original 31,047 SPCs issued at the Custom Houses of Fall River, Gloucester, New Haven, New London, Newport, Marblehead, and Salem. These certificates are indexed on the

Mystic (CT) Seaport Museum

      website database.

    1. Early Newspapers. Early printed materials in brochures, newspapers, and notices should not be overlooked. These records may be located at the State Archives, local state historical societies, or in library special collections. The Times, an early Charleston, South Carolina newspaper, stayed abreast of maritime events. In the 25 Jan 1813 issue, along with privateer and vessel updates, an article entitled Impressed Seamen was reprinted from the National Intelligencer.

The Library of Congress "American Time Capsule" collection holds digitized copies of the Impressed Seamen from Salem from the 30 March 1813 and 2 April 1813 "Salem Gazette".
