Dumnagual Moilmut, King of Bryneich
(Born c.AD 440)
(Welsh: Dyfnwal; Latin: Domnovellaunus; English: Donald)

Dumnagual was the son of King Garbonian and succeeded to the Throne of Bryneich upon his father's death, probably in the late 5th century. Little is known of him, but he seems to have been the prototype for Geoffrey of Monmouth's character of the same name who he transported back in time to a mythical landscape around 450 bc. This man was said to have had to fight many battles to secure his position as King but later became well established and was a wise and respected law-maker. With the epithet of Moel, he appears at King Arthur's Court in the tale of Culhwch and Olwen. Dumnagual was chiefly succeeded by his eldest son, Bran Hen (the Old), although the kingdom may have been divided amongst sons.
