Ancestry adds Ireland, Index to the Prerogative Wills, 1536-1810

Although original wills held by the Church of Ireland were victims of the 1922 Four Courts disaster an index to 38,829 of them survives.
Ancestry has made this available, as published by the Genealogical Publishing Co., 1989, and originally in 1897 by Sir Arthur Vicars in Dublin. The surviving index information includes both men and women.
A free searchable copy of the original publication is in the Internet Archives at https://archive.org/details/indextoprerogati00vica/.
