Dungarth, King of Dumnonia
(Born c.AD 705)
(Welsh: Dyngad; Latin: Doncatus; English: Duncan)

According to the Llyfr Baglan, Dungarth was the son of Culmin ap Brochmail, the king of a shrinking Dumnonia. He would have ruled in the mid-8th century and therefore cannot have been the better known King Dungarth who reigned in the late 9th century. His name is a variant of that of his supposed ancestor, Donaut.

This early Dungarth is generally considered to be chronologically misplaced.
