This site is run by the Irish Ministry of Culture and is really important for people with Irish ancestry as it contains:
• Searchable images for the whole of Ireland (including the North) of births 1864-1916; marriages 1870 to 1941 (Northern Ireland to 1922 only) and deaths 1878 to 1966 (Northern Ireland to 1922 only). More images are being scanned and eventually marriages will go back to 1845 and deaths to 1864, so keep checking back. This is really is a big deal as you have to pay for these types of images in Scotland, England and Wales.
• Some church records are also available on this site; see this page For a list of what is available.
Run by the Church of Jesus Christ of Latter Day Saints, this site contains a huge amount of records from all over the world. Some Irish ancestry records are held and probably the most interesting are:
• Ireland Births and Baptisms 1620-1881. These sets are incomplete; see this page for a coverage table by county.
• Ireland Marriages, 1619-1898. See this page for coverage by county.
The National Library of Ireland
All of the microfilms of Catholic parish registers that the NLI hold have been digitized and are available on this site to browse. These are images of most of the surviving baptism and marriage records to 1880. Some registers start around 1740-50, but most are later, some not starting until the mid 1800s. You need to know the parish where your ancestors came from as the records have not been indexed on this site. However, they have been indexed on Find My Past and you can search them for free, although you will have to set up an account.
