The final conveyance took place in 1315, and Sir John held it until his death before 1328–9. His widow Gille married Sir John de Molyns, and the latter acquired the manor of Aston Mullins from John the son and heir of Sir John Blacket. De Molyns obtained further security in this manor by releases of their respective rights from John Fitz Bernard and Giles and Isabel Blacket. Various letters patent and charters from the king were also obtained, one amongst them granting leave to Sir John de Molyns and his wife to embattle the house at Aston Mullins. (VCH)

John de Molyns, although described as the king's yeoman, was Treasurer to Edward III and was eventually knighted. His later career was an almost textbook 'robber baron'.
Moleyns (Molyns, Molines), Sir John (d. 1360), administrator and criminal, was the son of Vincent Moleyns and his wife, Isabella; he came from Hampshire, where his father had stood surety for a knight of the shire returned to parliament in 1301. His recorded career began in the royal household, as an adherent of the Despensers. In the autumn of 1325 he accompanied Prince Edward to France, and delivered a letter to the bishop of Winchester there. He married Egidia Mauduit, daughter of Sir John Mauduit and granddaughter of Robert Poges, who claimed a share of the manor of Stoke Poges, Buckinghamshire. Egidia and her husband profited from the murder of Peter Poges, lord of the manor, and his heir in the autumn of 1326, and Moleyns was later indicted of this crime but acquitted, though by a jury partly selected by himself. Stoke Poges became the centre of his estates which extended over thirty-one manors and tenements at the time of their confiscation in December 1340. (Röhrkasten)
