  Research Notes:

Source: A Genealogical and Heraldic Dictionary of the Landed Gentry of Great Britain & Ireland" by John Burke & John Bernard Burke, vol. I, London, 1847, p. 736 has:
"The eldest son [of Heilin ap Tudor and Agnes verch Bloddyn], GRIFFITH AP HEILIN, was father of GWILYM AP GRIFFITH, living 26 EDWARD III., who m. Efa, dau. of Griffith ap David, of Cochwillan, eldest son of Tudor ap Madoc, Lord of Penrhyn, in Caernarvon, (who d. about 1284,) grandson of Yarddyr ap Cynddelw, Lord of Uchaf, and had two sons, 1. Bleddyn ap Gwilym... 2. Griffith ap Gwilym, of Penrhyn"

Was Efa his wife? Or was she Gwen (i.e., swapped)? Swapping them (Eva as wife of Gruffydd ap Heilen) would bring Penrhyn and Cwchwillan into the family one generation sooner.

Source: The History of the Princes, the Lords Marcher, and the Ancient Nobility of Powys Fadog, and the Ancient Lords of Arwystli, Cedewen, and Meirionydd by J. Y. W. Lloyd, Vol. IV, London, 1884, p. 341, places Eva as the wife of Gruffydd ab Heilin, swapping her with Gwen. From that source re. Eva: "Eva, d. and heiress of Gruffydd ab David ab Tudor ab Madog of Penrhyn and Cwchwillan, son and heir of Iarddur, of Penrhyn and Cwchwillan, Lord of Llecchwedd Uchaf and Creuddyn, and Grand Forester of Snowdon."

Eva married Guilym ap Gruffydd ap Heilen Lord of Penrhyn and Cwchwillan, son of Gruffydd ab Heilen and Gwenhwyvar verch Jevan ap Gruffydd. (Guilym ap Gruffydd ap Heilen Lord of Penrhyn and Cwchwillan died after 1353.)
