Re: Thomas Meany of Kilrush born 1840
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).
For Mary Meany B 1836 +/- 1 yr somewhere in Ireland with a father forenamed Thomas, I found 4 rcds: 2-1836 Kilkenny, 1836 Limerick, and 1836 Clare.
For Thomas Meany B 1840 ditto, I found 1 rcd in 1840, Co. Limerick.
For Pat(rick) Meany B 1846 ditto, I found 0 rcds.
For Norry Meany B 1844 ditto, ditto.
For Denis Meany B 1845 ditto, ditto.
From your post, I imagine this family was desperately poor even before the Famine. The younger children may have been baptised, but it wasn't rcd'd for lack of the requisite "donation."
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.
Hope this helps. Good luck.
