Hopefully what I have come across may be of some help or perhaps I am off the mark.
I have found, on IrishGenealogy.ie the marriage of Catherine Condon to Dyonsus (Denis) Kiely on 5 March 1867 at Millstreet, Cork, Ireland.
Parents noted for Catherine Condon are Patrick Condon and Ellen Sullivan.
Parents noted for Dyonsus (Denis) Kiely are T Kiely and Julia Sheahan.
Interestingly the only baptism I could find with parents of Denis and Catherine is for Patrick Kiely on 1 May 1878 at Millstreet, Cork, Ireland.
Hope this is of some help to you.
