William de Valence, styled but never invested as Earl of Pembroke. [Burke's Peerage]
Lord Valence, Crusader 6 Mar 1250.
---------------------------
Earldom of Pemborke: Nevertheless Henry III's half-brother William de Valence, who married a niece of these last five [all sons of William Marshal, who died dspl] Earls of Pembroke, is sometimes referred to by contemporary sources as Earl of Pembroke. His Aspirations in that direction were promoted by the fact that Henry III had presented him with Pembroke Castle. In addition de Valence's widow Joan by dint of usage, plus inheritance of the feudal Lordship of Pembroke, came to be known as Countess of Pembroke. And their son, Aymer de Valence, who was no more formally created Earl of Pembroke than his father had been, was nevertheless coming to be generally recognized as Earl of Pembroke by some ten years after his father's death. Aymer's wife founded Pembroke College Cambridge. [Burke's Peerage, p. 2217]
