Breen is the maiden name of one of our maternal great-great-great-great grandmothers, Ann Breen. The sequence of surnames in the six generations between us goes Breen-Rogers-Rogers-Rogers-Rogers-Rogers-Dwyer.
The surname Breen is a variant of O’Brien which is common in Fermanagh and Ulster more generally, but also in Kerry and Wexford. Our Breen ancestors are linked with County Fermanagh.1
Our only known Breen ancestor is Ann Breen (c.1790-?). Her parents’ names are unknown.
