Your family names that are connected with your Breens do not show up on any of the information that I have uncovered in the Gorey area so far. Thanks for trying. There are still Breens in Gorey today and I have met some of them. They did not have enough information on their family to make it possible for me to make any connections. My great great grandparents, James Breen & Fanny Barrett Breen, left Gorey in 1850 and emigrated to Arkansas. James' brother, Patrick Breen & his wife Peggy Casey Breen, emigrated apparently to Alexandria, VA in early 1840s.
Let me know if I can help you.
