1st Lord Grandison. He is designated "of Lombourn Eaton and Asperton," Herefordshire, England. These may be misspellings of Llanwarne, Eyton, and Ashperton in Herefordshire. He was in the service of Edmund, earl of Lancaster. Edmund wrote to the King on William’s behalf when his lands were seized because he was an alien, pointing out the undesirability of such seizures. On May 3, 1292, he had licence to strengthen his house of Ashperton with a wall of stone and lime and to crenellate it. He was summoned to Parliament from February 6, 1298/99, to October 10, 1325, by writs directed Willelmo de Grandisono, whereby he is held to have become lord Grandison. He was in Gascony with Edmund before January 1, 1295/96, when his lands were restored to him. He was at the siege of Carlaverock in July, 1300. In 1318, the prior of the Hospital of St. John of Jerusalem complained that William de Grandison, and his sons Piers and Otes, had broken into his houses at Dartford, Kent, and robbed and assaulted. The Grandisons counterclaimed that there had been theft of their goods there. On September 20, 1329, he had respite of homage until the following Easter, the King having learned that he was so infirm and aged he was unable to come.
