Hi gene, I am also a descendant of Hugh Scallon m. Marie McCauley. They are my GGGgrandparents. I am descendant of their daughter Ann Scallon (b. 1788 ) m. To Patrick hangs McCaffrey. My tree is listed on ancestry.com titled MCCAFFREY/NUGENT/SCALLON. If you would like more info, pls contact me: firstname.lastname@example.org
PS. My records show Ann & Patrick arrived in Quebec approx between 1820 - 1823. Hope this helps you.
