Sir John Tregoze, Lord Baron Tregoze, only son and heir, did homage and obtained livery of his fathers' lands 52nd of Henry III, 1268, and stood in such favour with royalty that, notwithstanding his father's treason against Henry III, he was acquitted of 50 marks of รบ100, then due for his relief, after which he attended Edward I on the expedition into Wales. This Baron, during the latter part of his life, was summoned to Parliament from Jan. 26, 1296, to Feb. 6, 1299, and in 1300 was summoned to perform military service against the Scotch, but his death prevented it, for he died Aug. 21, 1300. He died seized of an immense inheritance. He married Mabel, daughter of Foulk, Lord FitzWarine, and this lady owned the Manor of Weston, in Bedfordshire, and the Hamlet of Sturden in Gloucester. By her Lord Tregoze had only two daughters, Clarissa, who married John de la Warre, and Sibilla, of whom further. At his lordship's decease the barony of Tregoze fell into abeyance between his grandson, John de la Warre, and his 2nd daughter, Sybilla de Grandison, as it still continues with their representatives.
