Hello Kathy,
Below is a transcript of the Civil Record which was kindly provided to me by another source which I believe you indicated you have. The additional notes at the end indicate the Church they were actually married in was Creemully and officiated by a Fr Martin Rush. It is located in the townland of Creemully and Aghagad Beg and was actually called St Kieran’s Church. My previous comment expands a little more on the Church.
If you refer to the linked map the Church they were married in is now St. Kieran's Community Centre/Former Parish Church and the current Church for the area is the adjacent Church of the Assumption, Castlecoote .
