Grey, John de (1305-1392) (DNB00)
GREY, JOHN de, third Baron (sixth by tenure) Grey of Codnor (1305–1392), soldier, born in 1305, was son of Richard de Grey (d. 1335), second baron, who was son of Henry de Grey(1254-1309) a grandson of Richard de Grey (fl. 1250) [q. v.] Richard de Grey, second baron (d. 1335), was one of the barons who at the assembly of Stamford on 6 Aug. 1309 drew up a letter of remonstrance to the pope on the abuses in the church (Annales Londinienses in Chron. Edw. I and II, Rolls Ser., i. 162). He was employed in the Scottish war in 1311, 1314, and 1319-20. In 1324 he was steward of Aquitaine, and was sent to defend Argentain (Knighton, in Scriptores Decem, 2543), and in 1326-7 was constable of Nottingham Castle. In 1327 he was employed in the Scotch marches, and was summoned for the Scottish war in 1334, but was excused on the ground of sickness. He died in 1335.
John de Grey took part in the wars of Edward III, in 1334, 1336, 1338, 1342, and 1346, in Scotland, and in 1339 in Flanders. In 1345 he accompanied Henry, earl of Derby, afterwards duke of Lancaster [q. v.], on his expedition to France, which was followed by a year's successful warfare in Guienne (Murimuth, Appendix, p. 243, in Rolls Ser.) He was again in France in 1349, 1353, and 1360. In 1350 he had license to go on a pilgrimage to Rome (Fœdera, iii. 440). In 1353 he was commissioner of array for the counties of Nottingham and Derby, and in 1360 was appointed governor of Rochester Castle for life. In 1372 he received a dispensation from coming to parliament on the score of his advanced age (ib. iii. 914). He is sometimes described as a knight of the Garter, but this is due to confusion with John de Grey of Rotherfield (1300-1359) [q. v.] He was last summoned to parliament 8 Sept. 1392, and seems to have died soon after. He married Alice de Insula, by whom he had a son Henry (d. 1379).[Rymer's Fœdera, ed. 1830; Dugdale's Baronage, i. 710; Burke's Dormant and Extinct Peerages, p. 248.]
