I don't actually know much about the Breen's at all. There are still some living there but I don't know anything about them. They are my grandmother's distant cousins. What I know is very sketchy. I don't know if I've mentioned this already but my ancestor's (Elizabeth Cullen) sister (kit Cullen) married a Breen and they had three daughters together. Dora, Nelle and Nancy were their names. Dora had one daughter who then had two daughters herself. As I said this is very little information and they form a small part of my tree. Sorry if it doesn't help.
