This name derives from the Middle English and Old English, meaning “dispute, deceitful, quarrelsome person”. The surname, after the given name, was introduced into Ireland by the Anglo-Norman invaders of 1169 and 1170. The former is regarded as Norman-French, deriving from the old French male given name Baraud, ultimately from the Germanic Ber(n)wald, composed of the elements "ber(n)", bear, plus "wald", rule. It is a popular Anglo-Irish surname, both in Southeast England, and Southwest Ireland. It is most common in the Irish counties of Mayo and Galway but particularly County Cork, and within England, East Anglia, especially Norfolk. The Gaelic version of the name is Barόid in the south and Bairéid in the west. Clare Barrett is an Irish clan, originally descended from Normans, which includes various septs including MacPadine, MacWattin, MacEvilly (Mac an Mhileadha), and MacAndrew.
