The old parishes of Killukin and Killummod are contained in the new parish of Croghan. B rcds for Croghan date from 1811, M rcds from 1825.
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 Edward Fitzmaurice B 1817, Croghan parish, Co. Roscommon, with a father forenamed Edward, I found 1 rcd.
There are no other Fitzmaurice Bs to a family headed by Edward in Croghan parish.
Possible offspring born to Pat(rick) Fitzmaurice in Croghan are Ann 1844, Frances 1837, John 1839, and Patrick 1841. It appears there was only one Fitzmaurice family headed by a Patrick in Croghan parish. A view of the detailed rcd SHOULD reveal the wife(s)' name.
