I research the Irish Family History Foundation's database. It contains 12,700,000 surviving rcds for abt 70% 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 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).
For ELLEN McKeon B 1908 (exact), Co. Leitrim, with a father forenamed Pat(rick), I found 1 rcd, in Mohill civil district.
For Mic(hael) Comer B ???? Ballyhaunis CP, Co. Mayo, with a father forenamed Mic(hael), I found 2 rcds: 1875 and 1987. The 1897 date is the more likely.
For Pat(rick) McKeon M 1903 +/- 4 yrs, Co. Leitrim, I found 5 rcds: 1902, 1904, 1905, and 2-1906.
For Susan Canning M ditto, I found 0 rcds either in Co. Leitrim, or in all other counties included in the current database.
For Michael Comer M 1993 +/- 4 yrs, Co. Mayo, I found 2 rcds: 1893, and 1897, both in Ballyhaunis civil district.
For Delia Kileen M ditto, I found 0 rcds anywhere in Ireland. This is a NO match.
For Pat(rick) McKeon M 1904 +/- 4 yrs, somewhere in Ireland, with a father forenamed, I found 1 rcd in
