Civil Registration - Birth, Marriages & Deaths At Sea (Overseas)
Registers of British and foreign passengers who were born, married or died at sea on British registered vessels or vessels registered in the colonies. The registers also included British subjects travelling on foreign registered ships carrying passengers to or from the UK. The registers were compiled from the ships' official logs and information given by the ship's masters to the Registrar General of Shipping and Seamen and its predecessor the Registrar General of Shipping and Seamen (RGSS). Be aware that problems occurred with the quality of record keeping on board as many passengers were not recorded at all by the authorities or the details about the passengers was often wrong. The RGSS transferred details of the event to the relevant General Register Office for England and Wales, Scotland and Ireland.
Deaths at sea have been officially registered since 1837 for deaths occurring in British waters and for vessels sailing from a British port. Up to 1889 separate series of registers were kept for seamen and passengers but in 1890 a combined series was introduced. In theory the event should appear in the appropriate local registry, however about a half of the events were never reported with the only record of the event remaining in these registers.
Also check newspapers for reports of disasters at sea. Searching the Official Index to The Times and Palmer's Index to The Times, 1790-1905 which carry lists of shipping accidents will show whether the incident attracted national coverage. Local newspapers might carry coverage and provide more details. If the accident occurred further afield then foreign newspapers should also be consulted. Another source for a death at sea can be found on memorials commemorating lives lost at sea which can be found at the port from which the boat sailed or nearer to the scene of the accident. The National Maritime Museum hosts a database of maritime memorials.
