I’m still searching the Foy family and have now received marriage certificates
Patrick Foy was indeed married to Bridget OBrien, they married at St Albans Chapel in Warrington September 1872, Patrick’s father was also called Patrick but was deceased at the time of the marriage.
Patrick Foy's father being Patrick rules out a Patrick Foy baptism in Kilcolman, Mayo (reply #4).
Have you looked at "Surname Interests" under "Your Tools" and added yours?
