Hi,
Although I am not a direct descendant of any Breens I do know of a family of Breens that live in Main Street. I don't know if you know of them. I am a bit sketchy but my Grandmother is more familiar with them. I am distantly related. I am from a line of Kinsella's of Gorey that married the Cullen's of Gorey. My great great grandmother had a sister called Kit who married a Breen. They had three children named Dora, Nelle and Nancy. I know Dora had at least one daughter named Mary. Mary then had a daughter named Breda Breen. There are more of them but I don't know what their names are. Does this help at all?
