David (St.) or Dewid, was son of Xantus, Prince of Cereticu, now called Cardiganshire; he was brought up a priest, became an ascetic in the Isle of Wight, preached to the Britons, confuted Pelagius, and was preferred to the see of Caerleon, since called St. Davids. He died 544. (See TAFFY.)
St. Davids (Wales) was originally called Menevia (i.e. main aw, narrow water or frith). Here St. David received his early education, and when Dyvrig, Archbishop of Caerleon, resigned to him his see, St. David removed the archiepiscopal residence to Menevia, which was henceforth called by his name.
