Historic baptism and marriage registers available for free online

The registers span over 200 years of Ireland’s history from 1671-1900, contain over 40 million names from over 1,000 parishes and cover 97% of the entire island of Ireland, both Northern Ireland and the Irish Republic.
This is the first time that the National Library of Ireland’s collection of Irish Catholic Registers (the most important resource for Irish ancestors prior to the 1901 census) has been fully indexed online and will make it easier than ever before for people to trace their roots back to Pre-Famine Ireland.
