Gruffydd Young
Gruffydd Young (or Griffin Yonge) (c. 1370 – c. 1435) was a cleric and a close supporter of Owain Glyndŵr during his Welsh rebellion against the English King Henry IV between 1400 and 1412.He was of illegitimate birth and won the favour of Queen Anne of Bohemia, the first wife of King Richard II of England.He allied himself to Glyndŵr in 1403 becoming Owain's Chancellor and by 1404 was in Paris, with Glyndŵr's brother-in-law John Hanmer and John Trevor the Bishop of St. Asaph negotiating a treaty of alliance with the French King Charles VI of France, or at least with his representative James II, Count of La Marche.Young instead was appointed as Bishop of Ross in the Kingdom of Scotland, by Pope Martin V, but he was never really in firm control of his diocese and was transferred to become titular Bishop of Hippo in North Africa along with two livings in Rheims and Tours in France.He was appointed abbot of the abbey of Le Thoronet, in the south of France, by Pope Martin V in 1430.
