The soke of William IV de Mohun (d. 1193) in London and Middlesex paid 13s. 4d. to the sheriff in 1197--8 and 1198--9.1 William's son Reynold de Mohun came of age in 1206, but died in 1213 leaving a son Reynold II (d. 1258), who came of age in 1227 and held the soke. Reynold may also have inherited Briwere land in Westminster through his mother after 1233.2 Reynold granted the soke of Mohun with all its appurtenances and liberties and advowsons of churches, within and without the city of London between the Fleet bridge and Charing, with his daughter Alice in marriage to Robert de Beauchamp of Hatch (Som.) and their issue c.1245.3 In 1252 Robert and Alice granted the soke with its homages, rents, reliefs, escheats, suits, pleas, liberties, and advowsons to Westminster abbey, to hold of Alice and her heirs; for this the abbot paid 85 marks and quitclaimed to Robert and his heirs the half mark annual service that Robert paid to the abbey for the manor of Shepperton.4 Thereafter the soke became part of the abbey's manor of Westminster, but the abbot may have continued to hold a separate court for the soke, or to account separately for its fixed rents, as it continued to be mentioned in accounts, as for example in 1327.5
