I research the Irish Family History Foundation's database. It contains 12,000,000 surviving rcds for abt 65% of Irish counties. Rcds are increasingly sparse B4 1840, rare B4 1800.
Note 1 - Without a KNOWN county, the chance of an ancestor's rcds NOT being in this database is AT LEAST 35%.
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).
For Peter Coleman M 1839 +/- 2 yrs somewhere in Ireland, I found 1 rcd in 1837 Co. Cork.
For Ann Johnson M ditto, I found 0 matching rcds to that for Peter.
For Peter Coleman B 1821 +/- 4 yrs in Co. Louth with the father's forename unknown, I found 1 rcd in Collon parish. However, the father's forename for this rcd is John, not Bernard.
For Brian Coleman B ????, Collon parish, Co. Louth, with a father's forename unknown, I found 0 rcds.
For Alice Coleman B ????, Co. Louth, ditto, I found 5 rcds, but the father wasn't Bernard.
For Bri(dget) Coleman B ???? ditto, I found 6 rcds, ditto.
For Bernard Coleman M 1821 +/- 1 yrs, Co. Louth, I found 1 rcd in 1821, Dundalk parish.
For Ann Morgan M ditto, I found ditto.
