Findmypast has confirmed today that it is to release a collection of 10million records from Irish Roman Catholic parish registers next month. This is the much-rumoured news that's been anticipated since last July when the National Library of Ireland uploaded unindexed images of the registers to its website at register.nli.ie.
The new indexed collection will consist of records from some 3,500 baptism and marriage registers covering all 32 historical counties of the island. They will link to the images.
The official press release says the records span from 1671 to 1900 but researchers should be aware that, other than a small number of exceptions, most start in the early 1800s and, as far as I'm aware, nearly all cut off at 1880–1882.
The new collection will be available through FindMyPast Ireland and World subscriptions.
