Reginald de Braose

Neither was present at the signing of Magna Carta in June 1215 because at this time they were still rebels who refused to compromise.

King John acquiesced to Reginald's claims to the de Braose estates in Wales in May 1216.

At this seeming betrayal, Rhys and Owain, Reginald's Welsh nephews who were princes of Deheubarth, were incensed and took Builth, except the castle.

Reginald and Graecia had a son, William de Braose, who was executed by Llewellyn Fawr, King of Gwynedd, upon being caught in the bedchamber of Joan, Lady of Wales.

It may be that the Matilda de Braose who was the wife of Rhys Mechyll, Prince of Deheubarth was the daughter of Reginald.
