The Complete Peerage quates Smythe's Berkleys as saying that
Margaret was the sister of William Marshall, Earl of Pembroke.
It further states that this identification of Margaret seems to
depend on Smythe's statement alone.  But the earl's other sister
was certainly the wife of Robert de Pont de l'Arche---as stated
by Smythe.
