From the bookReifsnyder-Gillam Ancestry, edited by Thomas Allen Glenn (Philadelphia, 1902), provided by http://books.google.com, p. 37:
"I. LLEWELYN AP TUDOR (descended from Ednowain ap Bradwen), Lord of the Comôt or Hundred of Talybont, Merionethshire; he did homage to Edward I, 1283, with the Lords and gentry of Wales for his lands in Talybont, and died before 9 August 1343 [footnote 2]. At the time of doing homage he produced his pedigree, with other evidences of his title to his lands, before the king's Commissioners.
"This pedigree was afterwards recorded by one David, scrivener to Iorwerth ap Llewelyn ap Tudor, his son, in a book appertaining to the Talybont and Estimaner estates from whence it was copied by William Lleyn, the Bard [footnote3] . The children of Llewelyn ap Tudor divided their father's lands between them.
1. Iowerth ap Llewelyn, living temp. Edward I. His scrivener, David, recorded the pedigree of his father, Llewelyn ap Tudor, in a book of accounts relating to the estates.
2. Ednyfed; of whom presently.
3. Llewelyn Vychan, m. Leuky, dau. Llewelyn ap Einion.
4. Peredyr Gethin (the terrible), from whom descended Gwenllian, wife of John ap Meredith, of Tal y Llyn (daughter of Ednyfed ap David), and grandmother of Mary, wife of David ap Howell; of whom later on."
"He was probably dead long before this date, at which time his grandson was seized of a part of his estate, and he is mentioned in an Inquisition, taken 1419, as formerly owner of a farm in Llangelynin bearing his name, 'Wele Llewelyn ap Tudor,' and then the property of a number of his descendants, who had parcelled it between them according to the custom of Gavel-kind."
"Yorke, 207. The pedigree of Llewelyn ap Tudor, as recorded by David, scrivener to his son Iorwerth ap Llewelyn, is as follows: Llewelyn ap Tudor ap Gwyn ap Peredwr ap Goronwy ap Adda ap David Gôch ap Griffith ap Ednowain ap Bradwen ap Mael ap Bleddyn ap Morudd ap Cynddelw ap Cyfnerth ap Cadifor ap Run ap Mergynawc ap Cynfawr ap Hefan ap Cadifor ap Maeldafhynaf ap Unwch Unarchen ap Yabwys ap Ysbwch, which Ysbwys and Ysbwch, father and son, came into Britain out of Spain with Aurelius and Uther, A.D. 466, and when Aurelius conquered Vortigern, he rewarded Ysbwch and Ysbwys, being among his officers, for their services, by a grant of the whole Comôt of Talybont, and part of Estimaner, in Merionethshire.
"Ednowain ap Bradwen, and his issue, says his historian, 'were possessed of all Talybont, save Nanney and the Princes demesnes, and, for the most part, of the hundred of Estimaner.' He had his house at Llys Bradwen, in Cregenan, Talybont. He was living about 1237."
