[1] The exact location of the manor buildings does not appear to be recorded, although it is assumed by most historians that they lay in the area of the current hall of Gray's Inn.
[4] On 12 August 1506 Edmund Grey, 9th Baron Grey de Wilton (d. 1511) sold to Hugh Denys (d.1511), Groom of the Stool to King Henry VII "the manor of Portpoole (one of the prebends belonging to St. Paul's Cathedral), otherwise called Gray's Inn, four messuages, four gardens, the site of a windmill, eight acres of land, ten shillings of free rent, and the advowson of the chantry of Portpoole."
The manor was bequeathed by Denys in his will to Sheen Priory, in Surrey, where he was buried, in trust for the augmentation of the Chapel of All Angels at Brentford End.
After a delay of five years involving a legal dispute during which a royal licence was being sought by Denys's executors to alienate the manor to Sheen, the Priory leased "the mansion of Portpoole" to "certain students of the law", at the annual rent of £6 13s.
After the Dissolution of the Monasteries the benchers of Gray's Inn were entered in the King's books as the fee farm tenants of the Crown, at the same rent as paid to the monks of Sheen.
