The records come from the Parish Register Society of Dublin (RPS), a group formed in 1905 to publish some of the records in the earliest registers from the Church of Ireland's parishes, then held at the Public Record Office at the Four Courts and subsequently lost in the 1922 fire. The organisation merged with the Association for the Preservation of the Memorials of the Dead. In total, the RPS published 16 volumes.
