Iorwerth Foel was of Pengwern. Mostyn (p. 17) argues that the place of Iorwerth Foel among the witnesses to the 1270 charter transcribed by Seebohm (Appendix D, pp.101-106) implies that he had succeeded to his father’s office of seneschal to the House of Northern Powys. Mostyn states that he was probably also then constable of Dinas Bran. He likely supported his uncle Llywelyn ap Gruffudd in the failed 1282 uprising, but received amnesty (Mostyn p. 18). In an undated document quoted by Rhys Cain, Roger de Mortimer, lord of Chirk, granted to Iorwerth Foel “the lands of of Gwern Osbwrn and Phen-y-Clawdd at a yearly rental of twenty pounds sterling in silver money.” (Mostyn p. 18) Iorwerth Foel joined Madog’s unsuccessful 1294 rebellion, and was pardoned in 1296. (Mostyn p. 20; CPR Edw. I 1292-1303, p. 186) In 1300, Iorwerth Foel rebelled again, primarily against Roger de Mortimer, who was converting common pasturage into forest. He was pardoned in 1301 of his outlawry for non-appearance before the king to answer a plea of trespass regarding the case (Mostyn pp. 20-21; CPR Edw. I 1292-1303, p. 567). Iorwerth witnessed a deed for land at Hanmer in 1313. (Mostyn p. 21)
His lands were in Nanheudwy, Swydd y Waun, and Maelor Saesneg (Carr, 1979, p. 140).

MS. 1654, B, fo. 311 (Cedwyn MS.); Ierworth foel fil’ Ierworth Fychan (chart of R. Mortimer); and Cae Cyriog MS., fo. 62), Dwnn (2:307-308), Lloyd (1:313), and Carr (1975, p. 9). Mostyn (pp. 16-17) notes that Iorwerth Fychan is mentioned as father to Iorwerth Foel in a charter of 1270 (“Yaruorth uoyl fił yaruorth uauhan”) and also in a grant by Roger de Mortimer. A transcription of the 1270 document is given by Seebohm (Appendix D, pp. 101 to 106. Iorwerth appears on page 105).

Children:
(Complete source citations for facts about the children on this page are currently outside of the scope of this project. The information below comes from Bartrum, Mostyn, Dwnn and Carr (p. 12). Sources disagree about the birth order. The birth order below is from Mostyn. Bartrum has: 1 Gruffudd, 2 Morgan, 3, Madog Llwyd, 4 Ednyfed Gam. Carr (1979, p. 140 fn) states that Iorwerth had ten recorded sons -- more than appear in the pedigrees.)
Ednyfed Gam married Gwladus ferch Llywelyn ab Madog.
Morgan.
Gruffudd of Maelor Saesneg. In Hanmer church, there was formerly a slab inscribed “Hic iacet Griffith ap Iorwerth Voel. Orate p.e.a.” (Mostyn p. 21)
Rhys.
Ieuan. Ieuan was a juror at Roger de Mortimer’s 1332 IPM . (Mostyn p. 21)
