de BLÁCA—XII—le Blak, le Blake, Blake; i.e., 'the black,' from the complexion; a descriptive epithet which in course of time supplanted the original surname, which was Caddell. Caddel was used as an alias for Blake as late as the 17th century, when it fell into disuse. The Blakes were one of the 'tribes' of Galway. The first of the family to come into prominence was Richard Caddel, or Blake, who was sheriff of Connacht in the early years of the 14th century, and from him are descended the many disdinguished families of Blake in Ireland.
