looking for ancestors

I am looking for any ancestors of John Mulleen and Catherine Prendeville. John and Catherine were married December 19, 1851, in Fermoy, Cork, Ireland, the Priest who married them was Matkin Collis, witness's to the marriage were Joseph Thompson and John Meyers.  Both of their address are listed as Fermoy, the Denomination for both is Church of Ireland. John Mulleen's occupation is listed as SOLDIER PRIVATE 59TH TH REGT., Catherine has no occupation listed both are over 21.  John Mulleen's father is listed as Fardy Mulleen, Catherine's father is Thomas Prendeville, no mother is listed for either.

John and Catherine had 2 children in Ireland Thomas Peter born Aug. 11, 1863 and Margaret born in 1864.  John and Catherine left Ireland in 1868 and immegrated to Ontario, Canada, they had 3 more children -  John, Edward and William.

John and Catherine Mulleen are my g,g grandparents, Thomas Peter is my great grandfather.

If there is anyone who knows anything aobut this family, I would be interested in hearing from them.

Thank you so much for your time.
