I searched the Irish Family History Foundation's database. It contains 12,000,000 surviving rcds for abt 65% of Irish counties. Rcds B4 1840 are increasingly sparse, B4 1800 rare. I only search the existing database.
For Ann(e) Coyle B 1833 +/- 1 yr, I found 3 B rcds: 1832 Oldcastle parish, 1833 Dunboyne parish, and 1834 Kildalky parish. The Oldcastle parish rcd looks promising. A view of the detailed rcd MAY show her parents' names and other info.
