Descendants

Some of Dafydd's descendants, who adopted the surname 'Games' to mark their connection to him, remained one of the most powerful families in the Breconshire area till Stuart times.[5] They were noted for their support for Welsh bards. His beautiful daughter Gwladys ferch Dafydd Gam, the 'Star of Abergavenny', made two good marriages, the first to Sir Roger Vaughan, who also died at Agincourt. Her second was to Sir William ap Thomas of Raglan Castle who survived the battle. Her son became the extremely powerful William Herbert, 1st Earl of Pembroke (1423-1469) and took the surname Herbert, later to become one of the most well known names in the nobility.
