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 parish, 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).
Mahoonagh parish rcds begin in 1810 for marriages and 1812 for births.
For Pat(rick) Kiely B 1829 (exact) in Mahoonagh parish, Co. Limerick with a father forenamed Cornelius, I found 1 rcd.
For Ellen B 1826 ditto, ditto.
For Johanna B 1823 ditto, ditto.
For Cath(erine) B 1820 ditto, ditto.
For Mary B 1817 ditto, ditto.
For John B 1815 ditto, ditto.
For Marg(aret) B 1813 ditto, ditto.
For Cornelius Kiely M 1812 (exact) in Mahoonagh parish, Co. Limerick, I found 1 rcd.
For Mary Guiry M ditto, ditto.
A view of the B rcds SHOULD show the correct parent's names. A view of the M rcds SHOULD show their parents' names, residence, and other info.
Google the Foundation's name to lead you to this database. Register, opt to be notified as rcds are added and browse. Pls post your search results to my genforum msg.
Thanks for having such precise information. Hope this helps. Good luck.
