Advice re finding a Will of 1808 in Limerick

Wills before 1858 were processed by Established Church Courts and known as Prerogative Court or Consistorial Courts, unfortunately when the system changed to the Probate Court in 1858 the documentation was sent to the Public Records Office in Dublin on the same site as the Four Courts - which was destroyed in a fire and explosions during the civil war. In most cases just the index entries survive, some transcripts and other sources do exist but none seem to cover Limerick Diocese for 1808 - see : Prerogative and diocesan copies of some wills and indexes to others, 1596 – 1858 (National Archives of Ireland).

A very long shot you could try checking the website of the Virtual Treasury/Beyond2022.ie which is working to recover as much information as possible from burnt fragments recovered fro the scene, and documents from other sources etc.
