General Notes

Sir William de Grandison of Asperton, County Hereford, was in service of Edmund, Earl of Lancaster. He was excepted from military duty in Gascony in 1294, in which year he appears as Governor of Jersey and Guernsey. He was summoned to Parliament from Feb. 6, 1280, to Oct. 10, 1325, by writs directed to Willimo de Grandisono, whereby he is held to have become Lord Grandison, and was present at a meeting of Parliament April 5, 1305, at the house of his brother, Otis de Grandison Archbishop of York in Westmenster. He was summoned to the Coronation of Edward II Jan. 18, 1307. 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, license was given him to remain at home for the more speedy restoration of his health, provided that he sent at least six men-at-arms for the expedition. On Sept. 20, 1329, he had respite of homage until Easter following as the King had learnt that he was so infirm and aged that he was unable to come. He was, however, summoned July 12, 1332, to be with the King at Michaelmas and take passage to Ireland on the expedition there. He married in or before 1285 Sybil, younger daughter of Sir John Tregoze of Ewyas, by his first wife Mabel, daughter of Fulke FitzWarine. On Nov. 26, 1300, it was ordered that the lands of Sir John Tregoze should be divided between William de Grandison and wife and the other co-heir they having done homage. Partition took place Dec. 1, 1300, by mutual assent. His wife died June 27, 1335 (Cokayne's Complete Peerage, Vol. 6, pp. 60/1).
William de Grandison was younger brother of Sir Otho de Grandison, who was Secretary to Edward I, and afterwards Lord Grandison. William was originally a menial servant to Edmund, Lord Pancaster, and obtained from that Prince in consideration for his own faithful services and the services of his ancestors a grant of the Manors of Radley and Menstreworth, County Gloucester. In the 20th of Edward I, 1292, he procured a license to make a castle of his home at Asperton, County Here ford, and in two years afterwards he was in the expedition made into Gascony, where he continued for some time, and while so engaged was summoned to Parliament as a Baron. He was afterwards engaged in the Scottish wars. His Lordship married Sibilla, daughter of Sir John Tregoze, and upon partition of the lands of that inheritance acquired the Manors of Burnham, County Somerset, and Eton in Herefordshire. He had issue by this lady three sons and three daughters: Peter, his successor, 2nd Baron Grandison; John, Bishop of Exeter; Otho, a distinguished soldier; Mabella married Sir John Patteshull; Katherine, of whom further; Agnes married Sir John Northwode (Burke's Dormant and Extinct Peerage, p. 242).
