I research the Irish Family History Foundation's database. It contains 12,800,000 surviving rcds for abt 70% of Irish counties. Rcds are increasingly sparse B4 1840, rare B4 1800. Cos. Donegal and Derry were recently added to the database.
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 Owen Keenan B 1837 +/- 8 yrs, somewhere in Ireland, with the father's forename unknown, I found 7 rcds: 1831 Armagh, 1832 Down, 1833 Armagh, 1836 Wicklow, 1839 Louth, and 2-1843 Westmeath. Father's respective forenames were Owen, James, Thos, Christopher, Bern, Edward, and Edward.
For Bri(dget) Skinner M ????, somewhere in Ireland, I found 0 rcds.
For Bri(dget) Skinner B ????, somewhere in Ireland, with the father's forename unknown, I found only 1 rcd within a relevant range: 1840 Co. Meath. Father's forename was Thomas.
The Skinner surname has only scant representation in Ireland.
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.
