Note 58a — Chapter VI · NEWPORT AND CAERDYF
Reading edition
The Coychurch Manuscript quoted by Mr. Williams, in his History of Monmouthshire, asserts that Morgan, surnamed Mwyn-fawr, or the Gentle, the son of Athrwy, not having been elected to the chief command of the British armies, upon his father’s death retired from Caerleon, and took up his residence in Glamorganshire, sometimes at Radyr, near Cardiff, and at other times at Margam; and from this event the district derived its name, quasi Gwlad-Morgan, the country of Morgan.
