I found a civil registration marriage certificate on irishgenealogy.ie, but can't find the corresponding Church marriage.
The marriage of Michael Reilly and Bridget McDonagh took place on 12th May 1874, at the Roman Catholic Chapel of Riverstown, Registration District Sligo.
I searched for Riverstown on
https://registers.nli.ie and found it was an alternative name for Taunagh. There is a marriage register for this parish, covering 1874, but it doesn't seem to contain the marriage I want.
I think I must be in the right area, because the priest's name on the civil reg. certificate is given as Owen Feeny, and several marriages on the Church register (which is in Latin) have priest's name Eugene Feeny.
Can anyone help me find the Church register? I have checked the indexes on findmypast and ancestry, but found nothing.
