Dunawd, or Dinoth is mentioned by Bede in his Ecclesiastical History as the abbot of Bangor, and although Browne Willis gives the dedication as Dinoth in the eighteenth century, later scholars, such as J.E. Lloyd and A.W. Wade Evans, proposed the foundation of the church as the work of Deiniol, with Lloyd citing problems of his presumed chronology. Given the association of Dunawd and Deiniol as father and son in the genealogies, it seems likely that both were venerated here by the later Middle Ages.
