St. Odrian, Bishop and Tutelar Saint of Waterford
COLGAN was not able to discover even the time when he lived. This rich and famous city was subject to the bishop of Lismore, (which see was founded by St. Carthag, in 631,) till the Ostmen being settled here, they procured a bishop for Waterford. Malchus, a monk of Winchester, was consecrated first bishop of Waterford by St. Anselm, at Canterbury, in 1096. For the sees of Dublin, Limerick, and Waterford were subjected to the metropolitan of Canterbury during the eleventh and twelfth centuries, whilst the Ostmen were masters in those cities. The sees of Waterford and Lismore have been united since the year 1363. See Wares Irish Bishops, p. 533.
