In 1316 his successor, Sir John de Grey, created a rent-charge on the property in favour of the prior and convent of St. Bartholomew, in Smithfield, to provide a chaplain to perform daily service in the chapel of the manor; and at an inquisition held in that year, at the Stone Cross in the parish of the Blessed Mary at the Strand, to know whether it would be to the King's damage if he granted the necessary permission, the jurors reported that the property was "holden of Robert de Chiggewelle by the service of rendering to the same Robert one rose yearly, and the same Robert holds the tenements, together with others, of the Dean and Chapter of St. Paul's, and the said Dean and Chapter hold the same of the king in pure and perpetual alms."[110] The grandson of Sir John de Grey, another Reginald, died in 1370, and was succeeded by Henry de Grey, under whom the first feoffment-in-trust of this property that we know of took place. For when he died in 1397 it was found by inquisition that Henry, Lord Grey de Wilton, held no land in Middlesex, because by deed he had enfeoffed Roger Harecourt, Justice for Co. Derby; John de Broughton, Escheator for the counties of Bucks and Beds; William Danbury; John Boner, rector of the Church of Shirland (one of the manors of the De Greys), and others, of his manor of Portpoole, called Gray's Inn.[111] This was probably in 1371. Similar feoffments-in-trust were made by successive Lords de Grey until 1506, when Edmund, Lord de Grey of Wilton, sold the manor to Hugh Denys, verger of Windsor Castle, and others, the said Hugh's feoffees.[112] Hugh Denys died in 1511, and by his will he desired that all such persons as had been feoffed of his manor of "Greysynte" should be seized of it to the use of his heirs, "until such time as the Prior and Convent of the Charterhouse at Shene, in the county of Surrey, have obtained of the king's grace sufficient licence for the amortisement" of the manor to them.[113] And five years later the necessary authority was granted, the manor being described as having escheated to the King, "by the death of Robert de Chiggewell without an heir," to be held to the annual value of L6 13s. 4d. At the dissolution of the monasteries the Benchers of Gray's Inn had to pay this amount to the Crown, instead of to the Charterhouse at Shene. Charles II. sold the rent to Sir Philip Matthews, and in 1733 the Benchers purchased it from parties deriving title from his co-heirs.[114] The hall of Gray's Inn dates from 1560; the chapel is of unknown, but of ancient date.
