Robert of Rhuddlan

Robbert was recorded to have served as a squire in the court of Edward the Confessor and appears to have come to the Welsh Marches before 1066 in the service of the king.

Later the same year Trahaearn counter-attacked and drove Gruffudd to seek refuge in Ireland, but Robert was able to take advantage of the civil war to seize the cantrefs of Rhos and Rhufoniog and to build another castle at Deganwy.

Gruffudd was imprisoned by Earl Hugh in his castle at Chester, but Robert seems to have been responsible for his capture, since he was the one to claim Gruffydd's lands.

He was killed by a volley of javelins, and the raiders sailed off with his head attached to the mast of one of the vessels.

Robert's lands in Gwynedd were now taken over by Earl Hugh of Chester, but the Welsh revolt of 1094 led by Gruffudd ap Cynan resulted in the loss of most of this territory.
