The Patent Rolls of this period also help to populate the King's Houses with recognisable historical characters. Robert de Mauley is almost certainly Robert de Morley, 2nd Baron Rodyn, who fought at the battles of Boroughbridge, Halidon Hill, Sluys (where he was captain of the English flagship) and Crecy. De Morley finished his career as Constable of the Tower of London between 1355-9.
