 A certain David was consecrated Bishop of Bangor in Wales, 4 April 1120; according to Malmesbury he was none other than the chaplain David Scotus.As bishop he took part in several English synods, and probably died in 1139, since his successor was then consecrated.But it is not easy to reconcile with the foregoing, the statement of the later historian Trithemius, that David became a monk under St. Macharius in the monastery of St. James in Würzburg, as this abbey was not founded until 1140.
