I have information on their son John Patrick's line through his daughter Elizabeth. Everything from Elizabeth down to present is current and correct. I have a list of all of John Patrick's siblings but that doesn't trace down to present (yet).
I have apparently a mis-spelling for Cath(e/a)rine since I have it in my tree as Catherine Mary O'Hearn. Are you sure it is spelled with an "a"? I would be happy to share what I have. Feel free to contact me by email since we seem to be tracing identical lines.
