Little is known about any of the children of Owain Glyndŵr. Gruffudd is recorded as being Owain"s eldest son and would-be heir to the crown of Wales had his father"s rebellion ultimately been successful in creating an independent Wales. They were defeated by Prince Henry of Monmouth, later to become King Henry V or possibly John Talbot, 1st Earl of Shrewsbury.
The exact place and date of this battle is subject to dispute, but the Annals of Owain Glyndwr call it the Battle of Pwll Melyn, near Usk.
The result appears to have been a major Welsh defeat, the capture of Gruffudd ab Owain Glyndŵr, and the deaths of Tudur and Rhys Gethin. Before being taken to the Tower of London was first imprisoned at Nottingham.
He was sent from there to the Tower of London and after six years died in prison of bubonic plague.
