I am a descendant of their son James who immigrated to Australia at 18. I have a copy of the family tree listing all decendants from his marriage to Catherine (Kate) Zeller up to and including myself. I know that James' father John was born in 1810 and that Mary was born in 1814 and they were married in 1832 in Ireland.

I would be happy to share and compare any of this information with you and am interested in finding out where John came from and tracing this tree further back. my email is kim_jordan@aapt.net.au
