Gruffudd Fychan II

Gruffudd Fychan (early fourteenth century – 1369) was Lord of Glyndyfrdwy and Cynllaith Owain in Powys and a descendant of the princes of Powys Fadog, with a claim to their hereditary title. He served the Earl of Arundel as steward of the lordship of Oswestry.

By his wife Elen, daughter of Thomas ap Llywelyn, he was the father of Owain Glyndŵr, who in 1400 raised the great Welsh revolt and claimed the title Prince of Wales. Gruffudd died in 1369.
