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 Pat(rick) Feeney B ???? in Co. Galway with a father forenamed Th(omas), I found 9 rcds: 1844, 1845, 1865, 1868, 2-1872, 1878, 1897, and 1914. None were in Spiddal.
For Jul(ia) O'Connor M ???? in Co. Galway, I found 11 rcds: 1834, 1874, 2-1884, 3-1886, 1891, 1892, 1894, and 1901. None were in the Spiddal parishes.
For Thomas Feeney M ditto, I found 15 rcds. None matched the dates for Julia. None were in the Spiddal parishes.
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.
