Clan Barrett

Clan Barrett (Irish: Clann Bairéad) is an Irish clan from County Cork that originally descended from Normans who came to Ireland with Strongbow in the 12th century. They are related to the ancestors of the Clan Barrett of County Mayo, who until recently were otherwise considered Gaelic in origin. Of the two, the Cork branch was considered numerically stronger, while the Mayo-Galway branch held more prominence in the Middle Ages.

The Barrett family gained influence and power through the centuries for services to various kings and nobles, such as in the 14th century when they served as underlords to the de Cogan family, and later when one John Barrett fought in the First War of Scottish Independence for the Crown.
