Royal Navy - Continuous Service Engagement Books, (Service Records) Ratings (Military)

Nature of Source

Records relating to ratings who entered the navy for a fixed period of an initial ten year period. For each engagement served, a Continuous Service Number was issued, also known as 'CS numbers'.

For the 18th century and much of the 19th century, ratings only signed up for a commission on a particular ship and was only employed for the duration of the commission. Therefore, naval rating's records are rarely indexed by name with no individual service records kept on a sailor. It is therefore imperative that the name of the ship is known to conduct research on a rating. After Continuous Service was introduced in 1853, centralised records were kept on individual ratings which established a professional structure to the Navy.

The following sources could be used to establish the name of the ship served on:
Seamen's Wills in series ADM 48; wills proved at the Prerogative Court of Canterbury which was used as the probate court for sailors who died abroad or at sea (see Royal Navy/Royal Marines - Casualty Records for more details)
Certificates of Service (see Royal Navy/Royal Marines - Certificates of Service - Ratings & Officers)
The Trafalgar Ancestors project aims to list all those who served in the Battle of Trafalgar and will provide amongst other things the name of the ship served on; parish marriage registers might record the name of the ship served on
Pension records especially ADM 73/1-35, Greenwich Hospital Pensioners' Admission Papers which are indexed by surname (see Royal Navy/Royal Marines - Pensions to the Wounded, Retired, Widows & Orphans - Ratings & Officers.

It is possible that a rating could be issued with more than one CS number. Ratings who joined before 1873 but continued in service beyond this date might also appear in the Registers of Seamen's Services.

Royal Navy ex-servicemen suffering mental illness were treated at Hoxton House in London until 1818 and thereafter at the Royal Hospital Haslar near Gosport, Hampshire until 1854. The records can be found at The National Archives in series ADM 102/415-20 for Hoxton House and in series ADM 102/356-73 for Haslar.
