Sir William de Grandison, of Ashperton, Herefordshire, &c., younger brother of Otes de Grandison, was in the service of Edmund, Earl of Lancaster. On 4 Nov 1288 he had letters of protection when remaining in Wales in order to fortify the castle of Carnarvon, and was still there 6 Nov 1289, taking the place of his brother, Otes de Grandison. On 3 May 1292 he had license to strengthen his house of Ashperton with a wall of stone and lime and to crenellate it. He was excepted from military service in Gascony in 1294, in which year he appears as governor of Jersey and Guernsey for his brother. He was summoned to Carlisle for Military Service 26 September (1298). He was summoned to Parliament from 6 Feb 1298/9 to 10 Oct 1325, by writs directed Willelmo de Grandisono, whereby he is held to have become Lord Grandison; and was present at a meeting of Parliament, 5 April 1305 at the house of his brother, Otes de Grandison, Archbishop of York, in Westminster. He was summoned again for Military Service and to various Councils from 7 May 1299 to 21 March 1332/3. He was in Gascony with Edmund, Earl of Lancaster, before 1 January 1295/6, when his lands were restored to him, seized by the Crown on an order to take all lands, &c., of alien laymen of the power of France, but William de Grandison was still in the King's faith. He was present at the siege of Carlaverock in July 1300. He was summoned to the Coronation of Edward II, 18 January 1307/8. On 23 February 1309/10 he had letters of protection on going beyond the seas. In 1318 the Prior of the Hospital of St. John of Jerusalem complained that William de Grandison and Piers, his son, and Otes, brother of Piers, and others had broken into his houses at Dartford in Kent and robbed and assaulted, to which accusation there was a counterclaim by William de Grandison that there had been theft of his goods there. Having been summoned for Military Service in 1322, he did not attend the muster, and his lands were seized; but the absence being due to severe illness, licence was given him to remain at home for the more speedy restoration of his health, provided that he sent at least 6 men-at-arms for the expedition. He had letters of protection going to Ireland 16 June 1327, and on 20 September 1329 had respite of homage till Easter following, as the King had learnt that he was so infirm and aged that he was unable to come. He was, however, summoned, 12 July 1332, to be with the King at Michaelmas and take passage to Ireland on the expedition there.

He married, in or before 1285, Sibyl, younger daughter and coheir of Sir John Tregoz, of Ewyas Harold, &c. Lord of Tregoz, by his 1st wife, Mabel, daughter of Sir Fulk Fitz Warine. On 26 November 1300 it was ordered that the lands of Sir John Tregoz should be divided between William de Grandison and his wife and the other coheir, they having done homage. The partition took place 21 Dec 1300 by mutual assent, but, after petitions concerning the knights' fees of Ewyas Harold, a final partition was made 29 October 1302. His wife died 21 October 1334, and was buried at Dore Abbey. He died 27 June 1335, and was presumably also buried at Dore Abbey.
