Marriage Records: Scotland, Ireland, Channel Isles

Not everyone hails from England or Wales, of course, and even for those living there, their ancestors might well have been born and married elsewhere. Scotland, the Channel Isles and the Isle of Man all operated relatively independently, while Ireland can pose its own problems (even when it was part of the United Kingdom, from 1800 to the early 1920s).
Scotland
In many ways, Scotland is an ideal place for a genealogist to research, In many cases records are more complete than south of the border, and they're all in one place, at the General Register Office in Edinburgh. A real bonus is that they're all available online at Scotland's People .Whilst official registration in England and Wales began in 1837, it didn't arrive in Scotland until 1855. However, those certificates add a couple of pieces of information to bring joy to a genealogist's face - the names and maiden surnames of the mothers of bride and groom (there are also questions asking whether the parents of the bride and groom are deceased). In the early years of registration there were also some other pieces of information included:
- If a widow or widower, whether this is the second or third marriage (used in 1855 only).
- The number of children by former marriages, both living and dead (1855 only).
- The relationship of the parties, if they are related (1855-60).
Channel Isles and Isle of Man
It might come as a surprise, but neither the Channel Isles (Jersey, Guernsey, Alderney and Sark) nor the Isle of Man has ever been part of the U.K. as far as civil registration is concerned. They have their own archives, register offices and libraries with record of marriages, birth and deaths (although their census returns are included with those of England and Wales. The Isle of Man records are in Douglas and date back to 1878. They began in 1860 in Guernsey, and two years later in Jersey.Ireland
The biggest problem with finding Irish records is that so many simply haven't survived. A Dublin fire in 1922 destroyed many records, including around half of the Church of Ireland's parish registers, making for a broken chain at best.The information on an Irish marriage certificate is largely identical to its English counterpart, although full registration didn't begin there until 1864. However, registration of non-Catholic marriages actually started in1845. A Marriage certificate pre-1957 consists of place and date of marriage, both spouses' name, age, marital condition, occupation and pre-marriage address and their fathers' names and occupations. Marriage certificates after 1957 consist of the date and place of marriage, spouses name, age, marital state, occupation and pre-marriage address, their parents' names and the spouses' intended place of residence.
Records are held in the General Register Office for Ireland in Dublin. Unfortunately, they're not available online.
From 1922 (when Ireland was officially divided), Northern Irish records are held by the General Records Office (Northern Ireland) in Belfast, and registers of marriage from 1922 are on computerised indexes there.
