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

Gruffydd married Gwenhwyvar verch Jevan ap Gruffydd, daughter of Jevan ap Gruffydd of Englefield, Flintshire and Unknown.
