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.

Between 1391 and 1403 he held various positions within the dioceses of St. Davids and Bangor, Gwynedd at Llanynys between Denbigh and Ruthin and Llanbadarn Fawr and then prebends at Garthbrengy near Brecon, Boughrood near Hay-on-Wye, Lampeter and Bangor itself.

He rose to be vicar-general at St. Davids and then Archdeacon of Merioneth.

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.
