Those aren't the only BMD records held at Kew. Audrey lists:

• Nonconformist and non-parochial registers, mainly from the 18th and early 19th centuries, handed in to the Registrar General of England and Wales.
• Registers from British consulates, legations and embassies, found among the records of the Foreign Office.
• Records of births and deaths on merchant vessels at sea, reported to the Board of Trade.
• Records created or collected by the various armed services.
