Why Merchant Seamen Leave Such a Rich Paper Trail

If you have a seafaring ancestor, you are luckier than you may realise. The merchant service was a regulated trade, and regulators love paperwork. Owners, the Board of Trade and the customs service all needed to know who was aboard a vessel, where it was going and whether the crew had been paid. The result is a mountain of records, much of it surviving, and many of it now indexed by name.

Better still, merchant records tend to give the two facts family historians crave most: a date and place of birth, and an address ashore. A single crew list can put your elusive ancestor in a specific street in a specific port town, and tell you which ship he joined next.

Crew Lists and Agreements: The Backbone of the Collection

From the 1830s onwards, ships' agreements and crew lists were deposited with the Registrar General of Shipping and Seamen. The great bulk survives from 1863, and the main series is held at The National Archives in Kew. Each list is a roll-call of everyone aboard: name, age, place of birth, rating, date of joining and leaving, wages agreed, and a signature or mark.

There is one crucial catch: crew lists are filed by ship, not by seaman. Before you can look anyone up, you need a ship's name, her official number and her port of registry. Those details often lurk in family papers, on a photograph, in a discharge book, or in shipping newspapers such as Lloyd's List.

Coverage is uneven. The surviving lists for 1863 to 1938 were divided between The National Archives, local record offices and the Maritime History Archive in Newfoundland, so a ship may be indexed in one place and filed in another. Some ports' lists simply did not survive. Persistence across several repositories usually pays off.

Registers of Seamen and Discharge Books

Where crew lists are filed by ship, the central registers are filed by man. A series of registers of seamen began in 1835, and the volumes covering the 1830s to the 1850s are indexed alphabetically by surname. They are patchy but can supply a first ship and an approximate age.

For the twentieth century the coverage is far better. The Fourth Register of Seamen, covering 1913 to 1941, survives as the CR1 and CR2 cards, and the Fifth Register continues to 1972. These cards are arranged by name and usually give a full date and place of birth — exactly what is needed to break a brick wall. Search The National Archives' Discovery catalogue under the Board of Trade record references.

Then there is the seaman's own discharge book, issued to him and often kept for life. If it survives in the family, it is a goldmine: consecutive ships, voyage dates, ratings and conduct notes, all in one place. Some were deposited with the official records too, so it is worth checking both.

Certificates of Competency, Apprenticeships and Fishing Fleets

Officers took examinations, and from the mid-nineteenth century onwards the resulting certificates of competency — masters, mates and later engineers — generated registers, application forms and sometimes photographs. These are particularly useful because an officer's career was continuous and well documented.

• Apprentices: indentures were registered, giving a boy's age, parent or guardian, and the ship he was bound to.
• Fishing fleets: trawler and drifter crews appear in separate agreements, plus port registers of fishermen and local customs records.
• Women: stewardesses, cooks and nurses served aboard passenger liners, and they do appear on crew lists. Do not assume a female ancestor is absent from maritime records.

Reading Between the Lines of a Crew List

Treat ages with a pinch of salt. A lad of fifteen might sign on as seventeen, and a man of forty-five might quietly become thirty-nine. Places of birth are often rounded to the nearest port town, and a seaman may name Liverpool one year and Birkenhead the next.

The real skill lies in following a man across several voyages. Compare signatures and marks — the illiterate seaman's "X" is less distinctive than a signature, but the shape of it, plus a consistent birth year and next of kin, can tie a common name to the right person. Ratings also tell a story: able seaman, boatswain, then lamp-trimmer suggests injury or age catching up.

Where to Find the Records — and How to Start

Begin with a ship, then work backwards from a known date. Even a single dated photograph, a family story about a wreck, or a line in a census can identify a vessel, and from there the crew lists open up.

• Search The National Archives' Discovery catalogue by seaman's name, ship's name and official number.
• Check local record offices for crew lists of ships registered in that port.
• Consult the Maritime History Archive in Newfoundland for lists not held at Kew.
• Try specialist maritime collections, including the National Maritime Museum's Caird Library, the National Records of Scotland and the National Library of Wales.
• Read shipping newspapers for arrivals, departures, casualties and missing vessels.

Build a timeline of ships and dates, and the man himself will slowly emerge from the ledgers: not just a name in a register, but someone who signed on at a particular dock on a particular morning, with a wage agreed and a voyage ahead of him.
