Will I am looking at old queries and I see a marriage of those two names in Callan, Co. Kilkenny on 20th January 1834, this is probably the brides parish, his address is Maxtown, a townland I assume and the witnesses are Nicholas Murphy and Julia Croak possibly Croke now.
YOu should be able to see the church register entry here: https://registers.nli.ie/parishes/0973
I have not looked for the children.
Good Luck
Pat
