Findmypast - Index of Irish Wills 1484-1858
This index only includes records at the National Archives of Ireland in Dublin. It also only includes records where there is a surviving document, like an original will, administration or grant of probate, a certified copy, a transcripts, or even abstracts and extracts. This means there is more information to be found on the original records. The index only deals with surviving records up to 1858 when the testamentary system was removed from Church control, and taken over by civil authorities.
