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 Ellen Daily M 1842 (exact) in Doneraile parish, Co. Cork, I found 1 rcd.
For Jeremiah Scully M ditto, I found 1 rcd for a "Jerh." The priest obviously used an abbreviation.
A view of the above detailed M rcds SHOULD show their parents' names and other info.
For Pat(rick) Scully B ???? in Co. Cork with a father forenamed Jeremiah, I found 1 rcd in 1844.
For Denis Scully B ???? ditto, I found 0 rcds.
For Ellen Daily B 1821 +/- 4 yrs somewhere in Ireland with a father forenamed Jer(emiah), I found 1 rcd in 1819 Cork. The parish wasn't Doneraile. You will need to view the detailed rcd to determine if it shows the expected parents.
For Jeremiah Daily M 1819 +/- 3 yrs somewhere in Ireland, I found 1 rcd in 1819 Cork. Again, a view of the detailed rcd SHOULD show whether the bride's name was Ellen. It should also list their parents' names. This is likely as far as you are going to get in the Irish rcds.
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.
