These are the only four children I could find to Denis & Catherine (McNally)Murphy. After Patrick was born they may have immigrated. I found a baptism for Denis Murphy on 30 January 1815 in Tinryland,co Carlow to Denis Murphy & Eleanor Gaynor. The only way to know if this is the correct one is to find a death cert for Denis & check the parents. As for Catherine, there are too many births, so you would need further identifying info to narrow down which cert may be hers.Hope this helps,Kim
