Ceredig ap Cunedda (died 453), king of Ceredigion, may have been born c. 420 in the
Brythonic kingdom of
Manaw Gododdin (modern
Lothian in
Scotland), centred on the
Firth of Forth in the area known as
Yr Hen Ogledd. Little is known of him. One of the sons of
Cunedda, grandfather of
Saint David, according to tradition, he arrived in what is now modern
Wales from Gododdin with his father's family when they were invited to help ward off
Irish invaders. As a reward for his bravery, his father gave him the southernmost part of the territories in north-west Wales reconquered from the Irish. The realm is traditionally supposed to have been called
Ceredigion after him.
