Notes to the Above.

1 Amongst positions preferred to Edward, Prince of Wales, at Kennington is one from thios Ynyr, stating that the King had given him the Office of Raglan of the Cosnot of Tal-y-Bont for his service in taking Madog ap Llywelyn, who in the last war had made himself Prince of Wales.

2 His tomb, on which is the following inscription, is still to be seen in Dolgelly Church – “ Hic jacet (or facet) Meurig Filius Ynyr Fychan”.

3 He was Tutor and Guardian to Meurig Vaughan (or Fychan) of Nannau, son of his brother Howell Selyf and was “the chiefest man in command in the County of Merioneth all his time” – as mentioned in the Roll of Peniarth.

4 Howell Selyf was slain by Owain Glyndwr and tradition says that his body was hidden in a hollow oak tree at Nannau (see Scotts’ Marmion).

5 He was a Cadet (younger son) of the Norman family of De Say, who came over with the Conquerer. A Great Grandfather, another Hugh Say, was Constable of Pool Castle 1411, a contemporary of David Holbech the founder of Oswestry Grammar Scool 1407.

6 Descended from Sir Griffith Vaughan (or Vychan), Knight, who was one of the captors of Lord Cobham (of the 1^st reformers) and who fought at the Battle of Agincourt. He was one of the earliest Knights of the Military Order of St John of Jerusalem (see notes to the Mabinogion by Lady Charlotte Guest, page 339).
