description: "Iorwerth Drwyndwn ab Owain was a Welsh nobleman of the 12th century. He was the son of Owain Gwynedd, king of Gwynedd, and his wife Gwladus ferch Llywarch, a noblewoman of Arwystli who was granddaughter of Trahaearn ap Caradog, once ruler of Gwynedd. This was his father's only legitimate marriage in the eyes of the Church. Little is known of Iorwerth's life or even the origin of Gerald of Wales' nickname for him, trwyndwn 'broken-nose', but he is remembered as the father of Llywelyn ab Iorwerth, prince of Gwynedd. Iorwerth probably held some land in the upper Conwy river valley after the death of his father in 1170, but he is not recorded in any source as having participated in the civil war which gripped Gwynedd following his father's death. Iorwerth probably died about 1174, and his son was thereafter raised in Powys."
