Church Records

The archives of the Church of Ireland and the Catholic Church (baptismal records, marriage records, and burial records) are primary sources of information for genealogists and family history researchers. Although many records were destroyed in the fire of the Public Record Office in 1922, many have survived, covering the majority of the population and a huge geographical area. Links to such records and introductions to reading such records can be found here.
