Hi Pat, Hugh was actually John's brother. John was the father of George (Isabella's huband) so therefore Hugh would have been Edward's uncle. Hugh was born in 1810. I think that would make you and I 4th cousins! Do you have any stories about Carraduffy passed down from your grandfather?
I am going to Ireland next week and was hoping to find some Cassidy's in Carraduffy that are related. Do you know of any that are still there? Or I would love to be in touch with your family and perhaps meet sometime since we are cousins. I live in Harpers Ferry, WV but on occasion visit the Philadelphia area. My email is email@example.com
