I research the Irish Family History Foundation's database. It contains 12,800,000 surviving rcds for abt 70% of Irish counties. Rcds are increasingly sparse B4 1840, rare B4 1800. Cos. Donegal and Derry were recently added to the database.
Note 1 - Without a KNOWN county, the chance of an ancestor's rcds NOT being in this database is AT LEAST 30%.
Note 2 - Only 1/2 of Co. Cork's rcds are in this database.
Note 3 - The RC church kept control over most parish rcds from Tipperary (north). These are ONLY available thru the Tipperary Family History Research center at a substantial fee (regardless of outcome).
Note 4 - Microfilms of parish church rcds are kept by the National Library of Ireland (NLI).
For Peter Delaney B ????, Co. Cavan, with a father forenamed Bernard, I found 1 1857 rcd, Crosserlough RC parish.
For Anne Delaney B ditto, I found 1 rcd, 1864, Crosserlough.
For Cat(herine) Delaney B ditto, I found 1 rcd 1866, Crosserlough.
For Pat(rick) Delaney B ditto, I found 2 rcds (1-church 1-civil), 1871, but neither in Crosserlough.
For John Delaney B ditto, ditto 1873, ditto.
For Ber(nard) Delaney B ????, Co. Cavan, with the father's forename unknown, I found 2 rcds: 1868 Crosserlough RC parish, and Kilnaleck RD.
For Bernard Delaney M ????, Co. Cavan, I found 1 rcd, 1841, Castlerahan RC parish.
For Cat(herine) Dolan M ditto, I found NO matching rcd. This infers the rcd may not have survived.
