Wales Merchant Seamen

Wales Merchant Marine

A merchant marine is a person who worked aboard commercial vessels. You may want to search merchant shipping records if you find one of the following terms in records about your ancestor: captain, mariner, seaman, mate, boatswain (bosun), or super cargo.

Records of Welsh ships and seamen can be found at the Cardiff branch of the National Museum of Wales and the Gwynedd Record Office. The latter publishes the following journal, which is a very good source of information on Welsh seafarers and their ships.

Gwynedd Archives Service, Editorial Board and Contributors. Cymru A’r Mor (Maritime Wales). Caernarfon, Wales: Gwynedd Archives Service, 1976–. (Family History Library book .)

Details about Welsh seamen can also be found with records about English seamen. The Board of Trade (BT) kept merchant marine records. Some are discussed in this section. The numbers for the record classes are added for convenience.

Ship’s Muster Rolls and Agreements and Crew Lists (BT 98). The ship master had to carry a written agreement with every crew member stating his wages, the capacity in which he was serving, and the nature of the voyage. These records were kept from 1747 to 1860. Pre-1854 records are arranged by port and ship number. Post-1854 records are arranged by ship number. Lloyd’s Marine Collection can provide the ship number.

Lloyd’s Marine Collection. This collection contains several types of records. One example is the captains’ registers from 1869 to 1947. These show the captain’s birth date and place, certificate number, examination date and place, the vessels on which he served, and death date.

More information about this marine collection is in:

Register of Seamen (BT 112, 119, 120). These registers contain copies of the certificates issued to individuals authorizing them to serve on a ship. The registers exist for the years 1835 to 1856 and give the man’s age, birthplace, date of first going to sea, rank, service record, and the ship’s name. Those from 1844 to 1856 give a physical description of the man. The registers for some years are indexed.

Births, Deaths, and Marriages Occurring On Board British Merchant Vessels (BT 158–60). Shipboard events were recorded in a ship’s log. They cover the years 1854 to 1890. Some of these records are indexed.

Surname Index to the 1861 Census Returns of Ships. This is an alphabetical list (Family History Library fiche 6025598, 8 fiche) of all people who were on board merchant and smaller vessels when the 1861 census was taken. Some naval ships are also included. These ships are not emigrant ships. The few passengers listed are usually family members of the crew. The information includes name, age, occupation, birthplace, name of the ship, and reference numbers for finding the records either in the Family Record Centre (see "Archives and Libraries" for the address) or in the Family History Library.

Census returns for other years include lists of persons on board ships. They are filed with the returns of the port city where the ship was docked.

Trinity House Petitions. These appeals for relief from poverty-stricken merchant seamen or their widows exist for 1780 to 1880 and often include birth, marriage, and death information. There are several Trinity Houses in Great Britain. Some of the records are indexed. For an index to the petitions for the London hospital, see:

The Trinity House Petitions. London, England: Society of Genealogists, 1987. (Family History Library book .)



Certificates of Competency and Service: Masters, Mates and Engineers (BT 121–127, 139–142). If a man wanted to become a master or mate, he had to take an examination. A certificate showing the name, the date and place of birth, and the date and place the certificate was issued was given to the man after the examination. Registers were kept of these certificates. They start in 1845, but few were kept until compulsory registration in 1850.

Two valuable pamphlets on researching merchant marine records are:

Records of the Registrar General of Shipping and Seamen. London, England: Public Record Office, 1983. (Family History Library book 942.1/L1 A3pa no. 5.) Discusses records available at the Public Record Office.

Watts, Christopher T., and Michael J. Watts.My Ancestor Was a Merchant Seaman: How Can I Find Out More About Him? Reprint with addendum. London, England: Society of Genealogists, 1991. (Family History Library book 942 U37w 1991.) This guide explains the contents of a variety of records as they relate to the merchant seaman, including Lloyd’s Marine Collection.

Foreign Consular Records. Foreign consular records include records of seamen who died at sea. The place where the seaman came from is often included. The records are listed in the Place Search of the Family History Library Catalog under:
