I searched 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.
For John Connor M 1825 +/- 4 yrs in Co. Meath, I found 2 M rcds: both in 1825.
For Bridget Kelly ditto, I found 4 M rcds: 1824, 1825 and 2-1826. The 1825 rcd is a tentative match with that for John. You will have to screen at the parish level to see if the marriages occurred in the same parish. If so, these are likely for your ancestors.
Google the Foundation's name to lead you to this database. Pls post your search results to my genforum msg.
