I only know of my ggg-grandfather - Edward Irwin - and possibly a brother named James that came to America. I have not yet made a definitive connection to the Irwins of Loughgall/Cloveneden. I was there 3 years ago but did not look up any Irwins while I was there as we only had a few hours in Loughgall. Does your dad have any family history going back to 1795? That is when my Edward Irwin was born. I did write several of the Irwin families that are still in Loughgall but did not get a reply from anyone. I would love to know what inforamtion you have on the Irwins.
