The Cobh Genealogical Project
This is a project which involves the computerising of all the Church of Ireland parish registers for the County of Cork. The Project also holds microfilm of all Cork County Church of Ireland Registers which are National Archives, and which escaped destruction in the Public Record Office in 1922. These contain marriage Records prior to 1845, and Baptism and Burial Records prior to 1870. Some go back to the 1650, but 1750 is more usual.
