Writ de escaeta, 26 Nov. Inq. Friday after St. Lucy, 45 Hen. III.
William, son of Reginald de Moun and the said Isabel, age variously stated as 6 and 7, is her heir.[Southampton.] Grewell manor was sometime the king's escheat through the death of Gilbert de Aquila, and the king that now is gave it to Gilbert Marescall to hold at the king's will for 4l. yearly, and by service of sending 10 men to reap for a day at Odiham in the autumn, the king feeding them, and doing suit at the hundred (court) of Odiham. Afterwards the said Gilbert gave the manor to Gilbert and Isabel Basset to them and the heirs of their bodies, and it was put in the charter that if the said Gilbert Marescall could not warrant them the manor against the king, he should give them land to the same value between Caversham bridge and Saverne water. And because the said Gilbert Marescall held at the king's will, and there is no heir left born of the said Gilbert and Isabel, the manor is the king's escheat through the death of the said Isabel.
