How to tell whether someone was in the Royal Navy or the Merchant Navy

In general, in family history, if your ancestor is called a ‘seaman’ in parish or census records, he served in the Royal Navy. However, ‘mariner’, ‘master’, ‘mate’ or ‘skipper’, mean he was probably a seaman or officer with the Merchant Navy.

How to find Merchant Navy records

Crew lists are the most important source for finding Merchant Navy records. When an individual joined a ship, his name was noted on the crew list and he signed articles of agreement. The resulting crew lists and agreements survive in The National Archives, the Maritime History Archive in Canada, and county record offices.

The best websites for finding Merchant Navy records

1. Crew List Index Project (CLIP)

Work on this wonderful resource for Merchant Navy records began in 2012. Volunteers marshalled by The National Archives and the National Maritime Museum (and with help from the CLIP team) began transcribing all of the surviving crew lists from 1915.

There are more than 39,000 crew lists here, featuring over 750,000 names. You can search for a crew member by forename, surname, rank, vessel name and/or birthplace. You can also search for a vessel, using its name or official number (vital for distinguishing between two vessels with the same name). There are also useful FAQs.

3. The National Archives (TNA)

The Registrar General of Shipping and Seamen kept Merchant Navy records, so most material is held in the Board of Trade record series (BT). There are guides to tracing merchant seamen for 1858-1917 and after 1917.

You can, for example, search and download registry cards of merchant seamen 1918-1941 via Findmypast. Southampton Archives has the originals. You can also search First World War Mercantile Marine Medal recipients on TNA’s website.

As detailed on the homepage: “A unique feature of the CR10 cards is that they usually contain a good passport style photograph of the seaman. They also contain personal and voyage start details.” You can search by surname; surname and forename; surname and initial; RS2/Identity Certificate Number; and add a year of birth.

5. Welsh Mariners
