Welcome to Ireland Reaching Out!
I looked at the November 10th 1845 marriage record and I think it pertains to your ancestors. Fedmore parish was right nex door to Ballybricken. I also looked on the subscription site Roots Ireland and found an 1817 baptismal record for a Bridget Hayes in Fedamore. This record shows a mother with the surname Cusack and one of the witnesses of the marriage was a Cusack. Maybe a coincidence or it is the correct record.?
