Births, marriages & deaths
The official recording of births, marriages and deaths by the government, known as civil registration, began in Ireland on 1 April 1845 for non-Catholic marriages and 1 January 1864 for all births, marriages and deaths. When the system was introduced, the country was divided up into registration districts and it became compulsory for people to inform their local registrar when a birth, marriage or death took place. It is worth noting, however, that some people were slow to comply with the new law. Under this system, registrars forwarded details of births, marriages and deaths to the General Register Office in Dublin until the division of Ireland in 1922. For a more detailed look at civil registration in Ireland see: Irish civil registration: where do I start?, An introduction to British civil registration and Ireland - Civil Registration Familysearch Wiki
Partition of Ireland - In 1922 Ireland was divided into Northern Ireland and the Irish Free State, now the Republic of Ireland. This division meant that there were two different systems of civil registration operating from 1922 onwards and two separate General Register Offices; one in Dublin for the Republic of Ireland and one in Belfast for Northern Ireland.
The Counties in Northern Ireland: Antrim, Armagh, Down, Fermanagh, Londonderry (Derry) and Tyrone.
The Counties in the Republic of Ireland: Carlow, Cavan, Clare, Cork, Donegal, Dublin, Galway, Kerry, Kildare, Kilkenny, Laois, Leitrim, Limerick, Longford, Louth, Mayo, Meath, Offaly, Monaghan, Roscommon, Sligo, Tipperary, Waterford, Westmeath, Wexford and Wicklow.
FamilySearch - Irish births, marriages and deaths appear on the Church of Jesus Christ of Latter-day Saints' website. Please note that records are incomplete and also that dates of birth have often been estimated from age at death.
The Irish civil registration indexes are also available on microfilm through FamilySearch Centres.
Irish birth, marriage and death certificates contain much less information than those for Australia. For a detailed breakdown of information recorded, see our guide: Information found on certificates for Australian states, New Zealand and the British Isles (PDF 34KB). Please note that the information recorded on certificates depends on the knowledge of the person who was informing the registrar. Therefore, some information may be missing or incorrect. Certificates for some date ranges have been microfilmed and are available through FamilySearch Centres. See the FamilySearch Ireland Civil Registration Research Wiki for full details of microfilms available. Certificates can also be ordered through the two General Register Offices:
General Register Office - Republic of Ireland - Apply here for copies of birth, marriage and death certificates for the whole of Ireland prior to 1922 and for the Republic of Ireland after 1922.
General Register Office - Northern Ireland (GRONI) - Apply here for copies of birth, marriage and death certificates in Northern Ireland after 1922. Some earlier certificates are also available through GRONI. See their website for details.
Finding births, marriages and deaths before civil registration
When searching in the period prior to civil registration (before 1845 for non-Catholic marriages and before 1864 for births, Catholic marriages and deaths) consult church registers where baptisms, marriages and burials are recorded. These events continued to be recorded by churches, so parish registers also provide information after these dates. To use parish registers, it is necessary to have some idea as to which parish is relevant to the person whose records are being searched. A valuable source of information about the location and extent of parish registers are the following publications Guide to Irish Parish Registers and New Genealogical Atlas of Ireland.
GENUKI Ireland - this website also has useful information about parish registers for some counties.
FamilySearch - One of the most important sources for parish registers is the extensive collection of microfilmed material available from the Church of Jesus Christ of Latter-Day Saints. Some of this material has been indexed on their website.
International Genealogical Index (IGI) is available on the old FamilySearch website. The IGI contains births and marriages, not deaths. Consult the microfilm of original documents which often has additional information. Microfilms can be ordered for a small fee from any of the FamilySearch Centres located around the world. Check the Library Catalogue to see what is available and obtain the relevant microfilm number for ordering.

Census and census substitutes

Use the State Library catalogue to find other census material relating to Ireland. Use keyword search 'census' plus the name of a geographic area e.g. Dublin census. For census substitutes try keywords such as land or taxation.
