Morgan was born at "Ynys-y-mwn", in the village of
Glais, near
Swansea, and he studied
Welsh at
Swansea University. In 1926, he met his future wife, Huana Rees, at the
National Eisteddfod of Wales. The couple wed in 1935. They had two sons: the politician
Rhodri Morgan (1939–2017) and historian
Prys Morgan (b. 1937).
Kate Roberts wrote
Traed mewn cyffion (Feet in Chains) which was awarded a prize at the National Eisteddford in Neath in 1934. Roberts won the prize jointly with
Grace Wynne Griffith and her novel
Creigiau Milgwyn. However it was alleged that
Creigiau Milgwyn was unworthy of the prize according to Morgan. A Welsh speaker, he was not a nationalist and opposed
Saunders Lewis. ''Y Treigladau a'u Cystrawen'', published in 1952, is generally considered his most important academic work. Morgan was Professor of
Welsh at
Swansea University from 1961 to 1975. He died suddenly at home in
Bishopston, Gower, and was buried at Coed Gwilym cemetery in Swansea. ==Works==
