This is a brief guide to researching records of births, marriages and deaths at sea (on British registered ships) or abroad.

These records were maintained by the General Register Office from the mid-19th century onwards, although their records and indexes are incomplete. Other records of British nationals overseas are held in many different places, so your search may be challenging.

Please note, the birth, marriage and death registers of former colonies were retained by the colony while details of births, marriages and deaths of Scottish and Irish people in another country will be in the relevant Irish or Scottish General Register Office.

1. What do I need to know before I start?

Any record made of a birth or death at sea from 1837 onwards was sent directly to the General Register Office and recorded in the Marine Register.

Statutory registration of marriages of English and Welsh people in other countries began in 1849. Marriages were registered in the relevant country before notification was sent to the General Register Office, so local records of marriages may exist in some countries.

When searching for records of a person try to find out:

  • the name of their parents, spouse or next of kin, where applicable
  • the approximate date of the birth, marriage or death
  • the area or ship where the event is likely to have taken place

2. What records can I see online?

Indexes of General Register Office overseas records (1761-2005)

Search the indexes of General Register Office overseas records on findmypast (£). The related certificates can be obtained from the General Register Office.

Births, marriages and deaths at sea on British registered ships (1854-1891)

Search digitised images from registers of births, marriages and deaths at sea on British registered ships (BT 158, BT 159 and BT 160) on  The Genealogist (£).

There was no obligation to keep records of births, marriages or deaths at sea before the mid-19th century.

Births, marriages and deaths on Royal Navy and merchant ships (1794-1972)

Search the registers of maritime births (1854-1960), marriages (1854-1972) and deaths (1781-1968) on findmypast (£), drawn from ten different record series (ADM 80/4-12, ADM 183/114-120, ADM 184/43-54, ADM 242/1-15, BT 153/1-22, BT 156/1-4, BT 157/1-9, BT 334/1-117, CO 386/170-172 and CUST 67/74). For some years within the ranges detailed above there are no records at all – use our catalogue to view descriptions of the ADM, BT, CO and CUST references listed for the precise breakdown of dates.

No merchant ship has ever been approved for marriages, although from 1854 any which took place had to be reported in the ship’s log. Any marriage which took place on board a merchant vessel was not legally valid.

Foreign registers and returns (1627-1960)

Search foreign birth, marriage and death registers (RG 32-RG 36) and download records on The Genealogist (£). Note the ‘advanced search’ option and ‘RG books’ tab which might be helpful.

The same registers are available on Ancestry (£) and can be browsed by The National Archives series (or class) and piece number or description.

3. What records can I find at The National Archives at Kew?

Foreign Office and Colonial Office registers of births, marriages and deaths of British subjects, c1820-c1950

Use the advanced search of our catalogue to search for consular registers of births, marriages and deaths of British subjects in other countries, as well as some registers from a few ex-colonies, in our Foreign Office (FO) and, to a far lesser extent, Colonial Office (CO) departments. We hold very few registers for ex-colonies as most were retained by the former colony. Search with ‘births’, ‘marriages’ or ‘deaths’ and, optionally, ‘register’.

For a list of the record series by country in which these registers are held, consult Tracing your Ancestors in The National Archives by Amanda Bevan (The National Archives, 2006; pp.76-90).

Records of inquiries into deaths at sea (1939-1995)

Consult records of inquiries into deaths at sea in BT 341 which include passengers of all nationalities on merchant ships.

Births, marriages and deaths in the armed forces

See our separate guide on finding records of births, marriages and deaths in the armed forces.
