Overview
Ednyfed Fychan ( 1170 – 1246), full name Ednyfed Fychan ap Cynwrig, was a Welsh warrior who became Seneschal to the Kingdom of Gwynedd in Northern Wales, serving Llywelyn the Great and his son Dafydd ap Llywelyn. Ednyfed claimed descent from Marchudd ap Cynan, Lord of Rhos, 'protector' of Rhodri Mawr, King of Gwynedd. He was the ancestor of Owen Tudor and thereby of the Tudor dynasty.
As is usual with medieval orthography, a variety of spellings were used for his name in medieval sources, such as Vychan, Idneved Vachan, and Edeneweth Vakan.
Warrior
Ednyfed is said to have first come to notice in battle, fighting against the army of Ranulph de Blondeville, 4th Earl of Chester who attacked Llywelyn, this act of war was at the behest of King John of England. Ednyfed cut off the heads of three English lords in battle and carried them, still bloody, to Llywelyn, who commanded him to change his family coat of arms to display three heads in memory of the feat. Ednyfed probably went on a crusade on behalf the English crown to the Holy Land around 1235, although the evidence is not conclusive.
Seneschal
In 1215, he succeeded Gwyn ab Ednywain as Seneschal of Gwynedd, roughly equivalent to Chief Councillor or Prime Minister. His titles included Lord of Bryn Ffanigl, Lord of Criccieth and Chief Justice. He was involved in the negotiations leading to the Treaty of Worcester in 1218 and represented Llywelyn in a meeting with the king of England in 1232.
