From Darrell Wolcott: " J.W.Y. Lloyd, in Powys Fadog vol ii, page 379 also mentions Jenkin Deweild (who he calls "of Holt") as the husband of Lleuci (1350) ferch Dafydd Llwyd (1320) ap Dafydd (1290) ap Thomas (1255) ap Rhys (1225) ap Hwfa Fychan (1190 and omitted in the PF pedigree) ap Hwfa Gryg (1160) ap Hwfa )1125) ap Sandde (1095) ap Elidyr (1060) ap Rhys Sais (1025). This tends to date Deweild as c. 1340, his daughter Tibod as c. 1375) and mother of Simon Thelwal (c. 1400)." (Steven Ferry, August 22, 2018.)
