Dictionary of National Biography, 1885-1900/Morgan (fl.1294-1295)
MORGAN (fl. 1294–1295), leader of the men of Glamorgan, appears, like his fellow-conspirator, Madog [q. v.], only in connection with the Welsh revolt which came to a head on Michaelmas day, 1294. In the 'Iolo MSS.' (p. 26) he is identified with Morgan ap Hywel of Caerleon,who belongs, however, to a much earlier part of the century (see Brut y Tywysoffion, Oxford edition, pp. 368, 370). His ancestors had been deprived of their domains by Gilbert de Clare, eighth earl of Gloucester [q. v.] Walter of Hemingburgh makes him, as well as Madog, a descendant of Llywelyn ap Gruffydd, but this is also a mistake. The movement led by Morgan resulted in the expulsion of Earl Gilbert, who then brought an army into Glamorgan, but failed to re-establish his power. About the middle of June 1295 the king appeared in the district, and soon restored order, receiving the homage of the tenants himself. Morgan submitted shortly afterwards, having been brought into Edward's power, according to Hemingburgh and the 'Iolo MSS.' (p. 26), by the northern leader Madog.
