Gwrast Lledlwm, King of Rheged
(Welsh-Gwrast, Latin-Gurgustus, English-Gurgust)
Gwrast the Ragged, the son of King Ceneu of Northern
Britain, was ruler of a huge Kingdom that covered the whole
modern North-West England. It stretched from Hadrian's Wall
above Caer-Ligualid (Carlisle) all the way down to Campoduno
(Leeds) in Midland Britain and Caer-Legion (Chester) in the East.
He ruled in the mid 5th century, but nothing else is known of him.
His epithet is intriguing.
