John de Sibton, ... successor [of Roger], sat as 11th Juror for Purslow Hundred at the Assizes of 1292. On February 1, 1294, he occurs as a knight and as in company with Richard, Earl of Arundel, at Haughmond Abbey. A money transaction, which he seems to have had with the Earl, has been noticed under Acton Round, and affords proof that he was living in 1304-5. I think that he left two sons, William and John. 1

Writ (of certiorari) to the escheator, on the complaint of John de Sibeton, that whereas he acquired 100s. of land in Acton la Rounde of Richard son of Alan, late earl of Arundel, three years before the earl's death, the escheator after the earl's death took the same into the king's hand and delivered it to Amadeus, count of Savoy, with other lands &c. of the said earl, which came to the king's hand by reason of the minority of his heir, and which the king caused to be delivered to the said count until the lawful age of the heir, 29 May, 32 Edw. I. (1304)
