Many registers for overseas Anglican chaplaincies are held by the Bishop of London or Bishop of Gibraltar archives. As early as 1633, the Bishop of London had responsibility for Anglican chaplaincies overseas where there was no local bishop.
In Europe, Anglican chaplaincies were established after the Reformation but the Bishop of London's jurisdiction over those in southern Europe ended with the creation of the Diocese of Gibraltar in 1842. The Bishop of London had responsibility for northern and central Europe chaplaincies until the 1980s. In 1980 a single diocese in Europe was created.
In North America the Anglican or Episcopal church was not under the jurisdiction of the Bishop of London after American independence in 1776. The first Canadian Anglican bishop held office from 1787 and most other British colonies had bishops installed during the nineteenth century. Registers from these colonial territories are not part the Bishop of London's archives. For India the records of baptisms, marriages and burials relating to the British and their families are part of the Asia, Pacific and Africa collections at the British Library and can be viewed online using FindmyPast.
Records of overseas chaplaincies are either the original registers which were returned to England or comprise the equivalent of bishops' transcripts or transcripts or copies produced by various people.
Original registers
There are no existing registers before the eighteenth century; many are from the nineteenth century. Chaplaincies within the diocese in Europe are more up to date as registers are still being deposited, although some European chaplaincies hold their own registers. Some nonconformist baptisms, marriages and burials have been recorded in the registers of local protestant churches. It may also be worth searching the memorandum books for both the London and Gibraltar dioceses.
Indexes
The London Diocesan Registry has indexed their foreign registers and register transcripts but the index is arranged alphabetically by the first letter of the surname and then by place. It also appears to use the old references, but once the system is mastered, there should not be any problem in finding the information you require.
Marriage allegations
Although in the United Kingdom the diocese was the one of the issuing authorities for marriage licences, there are very few allegations in the overseas records because, outside the colonial territories, licences were not granted by the diocese. However, some do exist for areas of Gibraltar and the British Embassy in Paris.
