benefactor of the cathedral church of Bangor [Ref: Moncreiffe RoyalAnc p10]

death recorded in Irish annals. Reasonably certain that he was a historical figure, however there are suspicious features in the earlier pedigree. The family claimed descent from Mailcun (modern welsh Maelgwn Gwynedd), a contemporary of the author Gildas (5th or 6th century) whose exact chronology is uncertain. The obituary of Maelgwn which appears in Annales Cambriae is a late fabrication, so the Annales Cambriae cannot be used to deduce a date for Gildas. [Ref: Stewart Baldwin SGM 6/29/1997]
