----------

Peter Fitz-Herbert, who, being very obsequious to King John, was reputed one of that prince's evil counsellors. In 1214, he was constituted governor of Pykering Castle, co. York, and sheriff of the shire; but afterwards falling off in his allegiance, his lands at Alcester were seized by the crown, and given to William de Camvill. Returning, however, to his duty upon the accession of Henry III, those lands were restored to him. He m. 1st, Alice, dau. of Roger Fitz-Roger, a great baron in Northumberland, but by her had no issue; and 2ndly, the 3rd dau. and co-heir of William de Braose, Baron of Brecknock, and d. 1235, leaving a son, Herbert Fitz-Peter.
