I am from the Quincy (Boston) area and my father is John A. Dwan originally from PEI where our ancestors came from Kilkenney county Ireland. My father is the son of Clifford Dwan who fathered 11 children. I don't know if this is any help to you, but I hope it is. Please email me and let me know. I am always interested in meeting more people in our family. As you know, our name is fairly rare so I feel that we may be related somehow. Take care and happy holidays.
