Padraig Mac Giolla-Domhnaigh

Brew—Brew is the anglicised form of the Isle of Man surname McBreive (Mac Breatheamh), the "son of the judge," from britheamh, judge. The Norse term Deemster superseded the Britheamh, or Judge, in the Isle of Man, and those of the name Deemster is undoubtedly a translation of McBreive and Brew.
