Richard ap Hywell ap Ieuan
(Mostyn), inherited Gloddaeth and Tre'r Garnedd by right of his mother. He presided at the first eisteddfod in 1523. (Richard) was grandson of Ieuan Fychan ap Ieuan ap Adda, of Pengwem, Llangollen (a descendant of Tudur Trefor), who, early in the fifteenth cen- tury, married Angharad, [grand]daughter and [eventual] sole heiress of Howel ap Tudur ap Ithel Fychan (or Vychan), of Mostyn (living 1407), Sheriff of Flintshire in 1390, a descendant of Edwin of Tegeingl. This Ieuan Fychan ap Ieuan ap Adda of Pengwem (a grand- nephew of Owain Glyndwr), was a man of great learning, and achieved some reputation as a poet.2 He volunteered for service in France, fought at Agincourt, was exempted from the Acts prohibiting Welshmen from holding office and bearing arms; and, after his marriage with the heiress of Mostyn, took a leading part in Flintshire affairs. He died 1457-8. Howel, of Mostyn and Pengwern, Ieuan's heir, was mortally wounded during the Wars of the Roses. He married Margaret, heiress of Gloddaeth. Their eldest son, Richard ap Howel, was at Bosworth Field, and died at a good old age, in 1539.
