Grenville belonged to a family which had settled in Devon soon after the Conquest. The family property as held in the early 14th century consisted of the manors and advowsons of Kilkhampton and Bideford. These estates, on the border between the counties of Devon and Cornwall, explain how Grenville, who was resident in Cornwall, naturally gravitated to Devon wherein lay the thriving port of Bideford. Through his marriage, which took place before his father-in-law’s death in 1391, he shared the Burghersh estates with Thomas Chaucer*, who married his wife’s younger sister, Maud. They included property in Lincolnshire, Oxfordshire, Surrey and Essex, as well as the manor of East Worldham, Hampshire, over which the Burghersh coheirs and their husbands fought a lawsuit with other parties in 1409.2 Grenville seems to have been the most influential member of his family up to that time, a position no doubt affected by his relationship with the Courtenays. He was a member of the retinue of his cousin Edward, earl of Devon, serving at sea from March 1387 under the admiral, Richard, earl of Arundel; and he was with his cousin in 1391 when the latter’s dispute with Sir William Sturmy* was at its height and the earl called Sturmy a ‘false traitor’. Indeed, it was he who delivered the earl’s message to (Sir) John Wadham*, one of the justices, that he should ‘sit more uprightly without partiality in this session than he had at the last’.3

Apart from his more normal activities as justice of the peace and of oyer and terminer, Grenville was concerned on several occasions with special business for the Crown. In 1402 he was a commissioner in both Devon and Cornwall to proclaim Henry IV’s intentions to observe the laws and customs of the realm, and was required to arrest all insurgents. In particular he seems to have had some concern with important military matters. During the Glendower revolt in Wales the King relied heavily on the West Country for men and supplies, and Grenville was ordered in September 1403 to take fish, ale, wheat and other victuals from Devon for consumption by the royal forces at Aberystwyth, Cardigan and Newcastle Em
