[3] Utilising the more advantageous property laws of England, Tudur saw to it that his lands were passed seamlessly upon his death in 1311 into the hands of Goronwy.

[1][4] Goronwy ap Tudur Hen was Lord of Penmynydd and a soldier in the service of the English crown.

[2][5] He joined King Edward II of England for his invasion of Scotland in 1314 as part of the First War of Scottish Independence, which included service at the Battle of Bannockburn in June of that year.

[8] After these troops, under the command of Gruffudd Llwyd, moved to Chester, they were dismissed on 4 August 1316 to return to North Wales in order to protect the area from the Irish threat.

[9] Goronwy and his troops were again summoned into the King's service to retake Berwick in 1319, after Scottish forces had taken it a year earlier.

[3][11] Goronwy was interred after his death in the west wall of the Franciscan Llanfaes Friary near Bangor, Gwynedd on 11 December 1331.
