Merchant Navy - Registers of Seamen/Service (Seamen)

Nature of Source

Registers of seaman employed in the Merchant Navy. The indexed Registers of Seamen were extracted and compiled from newly created Agreements and Crew Lists, established following the 1835 Merchant Shipping Act. The Act stipulated that the ship's master had to compile Agreements and Crew Lists and then lodge these with the Registrar General of Shipping and Seamen, (RGSS). The process created a central register of Merchant Seamen capable of serving with the Royal Navy if required at times of military conflict.

This separate Register of Seamen extracted from Crew Lists was abandoned in 1857, due to the problems of maintaining registers based on Crew Lists. Following three previous registration systems, a new Central Index Register (fourth register) was introduced in 1913 which survived until 1941 followed in 1942 by a new Central Register of Seamen (fifth register) which lasted up to 1972. Unfortunately no records exist from 1973 to 1999 as legislation was not required to keep records of individual seamen. From 1999 onwards the Registry of Shipping and Seamen in Cardiff holds records of service extracted from the ships official logbooks and crew agreements.

Therefore between 1857 and 1913 the names of seamen will only be found in the Crew Lists. However between 1845 and 1854, the authorities established an entirely new system whereby every mariner had to apply for a Register Ticket (See Registered Ticket Records). This system proved unpopular and unworkable and was replaced by a new register which lasted until 1857.

The registration system underwent a number of revisions over the years of operation and is classified into the following series of registers:

Series I (1835-1836, TNA series BT 120)
Series II (1835-1844, TNA series BT 112 indexed in BT 119)
Series III (1853-1857, TNA series BT 116)
Series IV/Central Index Register (1913-1941. Unfortunately entries between 1913 and 1918 were destroyed in 1969. The originals are held at Southampton Archives with copies available at TNA in series BT 364 as a combined index of the CR1, CR2 and CR10 cards)
Series V/Central Register of Seamen (1942-1972, TNA series BT 382)

Merchant Seaman records sometimes identify a vessel an individual served on only by the Ships' Official Number. The Crew List Index Project (CLIP) offers a searchable index of ships by official number. The database includes every British registered ship from 1855 to the early 1950s with official numbers 1 to 200000. In addition CLIP offers a searchable index of ships by name. It shows matching names and their official number, sorted first by name, then by official number.

Most Merchant Seaman records survive from 1835 following the introduction of the Merchant Shipping Act which introduced for the first time a central register of seamen. Before the Act few records merchant seamen records exist as seamen were employed for the duration of the contract and then made redundant. Those serving as officers may be easier to locate. Those working in the Merchant Navy below the rank of the officer class are mostly referred to as 'seamen' or 'mariners' whilst those serving in the Royal Navy are mostly referred to as 'ratings'.

To trace the voyages and obtain information on a particular vessel as well as obtain the captain's name, consult the Lloyd's Register of Shipping which is available at the National Maritime Museum as well as other repositories. Many editions covering the 18th and 19th centuries are available to view online at Google Books which also offers the facility to conduct a text search for the names of vessels and captains.

The registration number of the seamen being researched will be needed to look up his details in the registers. This can often be found in the Crew Lists or can be found in the alphabetical name index of seamen in series BT 119.

Merchant Navy mariners were recorded in the 1841 census but unfortunately not those on board ships either stationed on shore or at sea. They were first recorded on board vessels in port from 1851 (1861 for Scotland) and from 1861 measures were taken to record mariners at sea. However the coverage, especially for the earlier censuses, is patchy with many not appearing in the schedules. For more detailed information on the census and Merchant Navy see here and here.

Also look for Seamen's Pouches which contained various official items relating to the career of a merchant seaman. The pouches could include records from series IV and V of the seamen registrations as well as photographs of the seaman. Unfortunately out of the 500,000 or so pouches around 95,000 were destroyed mid 20th Century. The records are held in series BT 372. The name index covering series BT 372 is available at the TNA Discovery catalogue. First select advanced search from the Discovery home page and enter the name being searched. In the ‘Search for or within references’ box type BT 372 and then scroll down to ‘Held by’ and click ‘Search The National Archives’. Finally click the search button. Further filters appear on the search results screen. The series can also be directly searched from the series catalogue entry
