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.

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

Try to find out:

  • the person’s name (and 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?

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?

Records of overseas births, marriages and deaths from the Foreign Office and Colonial Office (c1820-c1950)

Consult records of overseas births, marriages and deaths in various FO and CO series.

These records are not searchable by name on our catalogue and are held in various record series. Read Tracing your Ancestors in The National Archives by Amanda Bevan (The National Archives, 2006) to obtain a record reference from a comprehensive list arranged by country.

Please be aware very few registers exist within Colonial Office records held at The National Archives. Most were retained within the former colony.

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.

6. Did you know?

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

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.

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.

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.
