Biography

Updated 18 August 2013

William de Grandison (died 1335), was an English noble, and Deputy Justiciar of North Wales. He was created “Baron Grandison” by writ of summons dated 21 September 1299, the same as his older brother, Otho.

Brief biography

From Burke’s:

1st Lord Grandison

William de Grandison (younger brother of Sir Otho de Grandison, secretary to King Edward I, and afterwards Lord Grandison), being originally a menial servant to Edmund, Earl of Lancaster, obtained from that prince,in consideration of his own faithful services and the services of his ancestors, a grant of the manors of Radley and Menstreworth, co.Gloucester. In the 20th Edward I [1292], he procured license to make a castle of his house at Asperton, co. Hereford, 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 m. Sibilla, youngest dau. and co-heiress of Sir John deTregoz, and upon partition of the lands of that inheritance, acquired the manors of Burnham, co. Somerset, and Eton, in Herefordshire. He had issue by this lady, viz., Peter, John, Otho, Mabella, Katherine, and Agnes. Hislordship d. before 1335 and was s. by his eldest son, Peter de Grandison,2nd baron. [Sir Bernard Burke, Dormant, Abeyant, Forfeited, and Extinct Peerages, Burke's Peerage, Ltd., London, 1883, p. 242, Grandison, Barons Grandison]

Origins

William de Grandison, 1st Lord Grandison, was born say 1251, (underage in 1263) probably at Vaud, Switzerland. The birth date is based on him joining his brother in England in service to Edmund of Lancaster.

William was a younger son of Pierre de Grandison and Agnes Neufchâtel. He was the younger brother of a key ally and envoy for King Edward I of England, Otto de Grandson.

Grandison was an anglicisation of the name Grandson.

Alternate parents

Alternately, his parents were Amadeus de Grandison (1229-1300) and Benoite de la Tour (1233-1278) [fn1][fn2]

William was the younger brother of Otto de Grandison:

1. from: Otto de Grandison: [Otto was] ... a Savoyard knight whose father was Peter, Lord of Grandison, near Lausanne in Switzerland. The young Otto travelled to England, probably in the company of Peter I of Savoy in 1252, certainly not later than 1265. There he entered the service of Henry III and by 1267 was placed in the household of the prince Edward. In 1268 both prince and servant were knighted and in 1271 the latter accompanied his lord on the Ninth Crusade, where he served at Acre that year. According to one source, it was Otto, not Eleanor of Castile, who sucked the poison from the wounded Edward after an attempted assassination.

2. from: From William the Conqueror to Lord of the Isles Otto de Grandison. Note: there is a dispute among Medieval genealogists over whether Otto and William de Grandison were the sons of Amadeus de Grandison or his brothers. Chronologically it seems very unlikely that the latter was true, but as always, dates of birth and death in the 13th century can be very inaccurate.

Family

William Grandison married second in or before 1285 to Sibyl de Tregoz (1271-1334). She was the younger daughter and coheir of Sir John Tregoz, by his first wife, Mabel, daughter of Sir Fulk Fitzwarin.

First marriage

https://fmg.ac/Projects/MedLands/ENGLISHNOBILITYMEDIEVAL3D-K.htm#Ka...

GUILLAUME de Grandson, son of PIERRE [II] Seigneur de Grandson & his [second] wife Agnes de Neuchâtel ([after 1250]-27 Jun 1335). Under age in 1263: … m firstly [1275?] Jeannette de Gruyère, daughter of PIERRE [II] Comte de Gruyère & his wife Ambrosie --- (-before 1284)]. … Bearing in mind Guillaume’s likely birth date it is probable that the couple did not marry before [1275]. The possibility of this Grandson/Gruyère marriage seems good, especially as Jeannette’s older brother was already married to Guillaume’s sister.]

Guillaume & his first wife had [two or more] children:

• 1. two or more sons. Their existence is confirmed by the 1306 indult cited above granted to their stepmother to hold services for the souls of “the elder sons of her said husband”. Besides the two possible sons named below, Williams discusses other possible children of Guillaume’s first marriage[491].
• 2. [GERARD de Grandson (-[before 1306]).
• 3. [JOHN de Grandson (-[before 1306]). Williams suggests that Guillaume’s sons by his first marriage (deceased in 1306 as noted above) may have included John de Grandison who is named in the following document[495], although if he is correct Guillaume would have had two sons named John, one from each marriage.
• 4. [AGNES ([1282/83]-Ruskington, Lincolnshire 11 Dec 1357, bur Ruskington All Saints). Williams discusses Agnes wife of Thomas Lord Bardolf as another possible child of Guillaume de Grandson by his first wife[497].

m secondly (1285 or before) SIBYLLA de Tregoz, daughter of JOHN de Tresgoz & his wife Mabel FitzWarin (before 1270-21 Oct 1334, bur Dore Abbey). Guillaume & his second wife had ten children: …

Second marriage

https://en.wikipedia.org/wiki/William_de_Grandison,_1st_Baron_Grand...

William married Sybil, daughter of John de Tregoz and Mabel FitzWarin, they are known to have had the following known issue:

• Edmund de Grandison
• Piers de Grandison, married Blanche Mortimer.
• John de Grandison, Bishop of Exeter.
• Thomas de Grandison, cleric.
• William de Grandison, Archdeacon of Exeter.
• Otho de Grandison, married Beatrice Malmayns, had issue.
• Mabel de Grandison, married John de Pateshull, had issue.
• Katherine de Grandison, married William Montagu, 1st Earl of Salisbury, had issue.
• Agnes de Grandison, married John Northwode, had issue.
• Maud de Grandison, nun at Aconbury Priory.

Legacy and Estate

https://www.wikitree.com/wiki/Grandison-2

Issue 3 sons and a daughter. Piers, John Bishop of Exeter, Otho. But names 3 daughters, Mabella, Katherine and Agnes.

An Inquisition Post Mortem taken at Gloucester, Thursday after the Conception, 18 Richard II (writ dated 21 October that year), following the death of Margaret, widow of Thomas de Grauntson (sic) son of Otes de Grauntson, names the following sisters for Otes: Agnes Northwod, Katherine mother of William earl of Salisbury, and Mabel.[4] These are clearly children #4, #10 and #6 in the current list (although Katherine should appear before Mabel). The full set of relationships described is:

• Roger Northwod son of John Northwod son of Roger son of Agnes sister of Otes de Grauntson, father of the said Thomas
• William earl of Salisbury, son of Katharine second sister of the said Otes
• Thomas Faukunberge, son of Maud daughter of Sybil daughter of Mabel third sister of the said Otes
• Alice late the wife of Thomas Wake, daughter of the said Mabel
• John Tudenham, knight, son of Katharine, daughter of the said Mabel
• Roger Beauchamp, son of Roger son of Sybil daughter of the said Mabel

This would seem to cast doubt on some of the children attached to this profile, although it could be that they all died without issue, or that there was some prior arrangement that meant that Otes' share only reverted to those three sisters.

There were several Inquisitions following the death of Thomas son of Otes, for which the writ was issued 9 November, 49 Edward III.[5] These show that he died at the age of forty on Thursday the feast of All Saints last. The facts relevant to his family tree are:

• Thomas held the manor of Dymmok in fee tail. King Edward I granted it, together with 46l. 6s. 3d. rent in the manor and town of Derteford, co. Kent, to William de Grandissono and Sibyl his wife, grandfather and grandmother of the said Thomas, to wit, father and mother of Otto his father
• as he died without heir of his body, his next heirs are William de Monte Acuto, earl of Salisbury, aged 40 years and more, son of Katharine one of the sisters of the said Otto, John Northwode, knight, of Kent, aged 30 years and more, son of Roger son of Agnes another sister of Otto, Roger Beauchamp, aged 13 years, son of Roger son of Sibyl daughter of Mabel a third sister of Otto, Thomas Facombergh, knight, aged 30 years and more, son of Maud another daughter of the said Mabel, Alice wife of Thomas Wake of Bl[isworth], knight, aged 50 years, a third daughter of the said Mabel, and Katharine late the wife of Robert Todenham, knight, aged 50 years, a fourth daughter of the said Mabel (This accords with the detail in the IPM for Margaret.)
• Peter de Graunson, his uncle, was seised of the manor in demesne as of fee, and gave it to him and the heirs of his body, with remainder to Elizabeth la Despenser and her heirs.

HISTORICAL HOME, SWITZERLAND: The Grandson family is first mentioned in the second half of the 11th Century as Grancione. The town was first mentioned around 1100 as de castro Grancione. Around 1126 it was mentioned as castri Grandissoni and in 1154 it was called apud Grantionem.[3] (wikipedia)

Birth: 1262 Vaud, Switzerland Death: Jun. 27, 1335 Herefordshire, England

William was the son and heir of Pierre de Granson, Seigneur de Granson on the Lake of Neufchâtel, by Agnes, daughter of Ulric, comté de Neufchâtel, and grandson of Ebal IV, Seigneur de Granson. He was the younger brother of Otes de Grandison. William was in the service of Edmund, Earl of Lancaster, who, on his behalf sent a letter to the King (when William's lands were seized, he being an alien), pointing out the undesireability of such seizures. On November 4, 1288, he had letters of protection when remaining in Wales in order to fortify the castle of Carnarvon. He was excepted from military service in Gascony in 1204, in which year he appears as governor of Jersey and Guernsey for his brother Otes. He was summoned to Parliament from February 6, 1298/99 to Oct 1325, where he is held to have become Lord Grandison. He was again in Gascony with the Earl of Lancaster before January 1, 1295/96, when his lands were restored to him. He was present at the siege of Carlaverock in Jul 1300, and was summoned to the coronation of Edward II on January 18, 1307/08. On November 26, 1300, it was ordered that the lands of Sir John Tregoz should be divided between William and his wife and the other coheirs. In 1318, the Prior of the Hospital of St. John of Jerusalem made complaint that William and his sons, Piers and Otes, with others, had broken into his houses and robbed and assaulted, to which William responded that there had been theft of his goods there. When he did not attend a muster for military service in 1322, his lands were seized, but as his reason for inattendance had been severe illness, he was excused and given license to remain at home, provided that he send at least 6 men-at-arms for the expedition. In June of 1327, he had letters of protection for going to Ireland, and on September 20, 1329 had respite of homage until the following Easter, as the King had learned that he was so infirm and aged that he was unable to come. However, he was summoned in July 1332, to be with the King at Michaelmas and take passage for the expedition to Ireland. He survived his wife, Sibyl, younger daughter and coheir of Sir John Tregoz, she dying Oct 1334, he following her in June 1335. Their children were Catherine, Piers and Agnes.

Biography

Updated 17 August 2013

William de Grandison, 1st Lord Grandison, was born circa 1263, probably at Vaud, Switzerland. He died 27 June 1335 at Harpenden, Hertfordshire, England and was presumably buried at Dore Abbey there. He was known as The Burgundian Knight.

He was known as the younger brother of Otto de Grandson, so therefore, as the son of Pierre de Grandison by his wife Agnès de Neuchâtel.

William Grandison married second in or before 1285 to Sibyl de Tregoz (1271-1334). She was the younger daughter and coheir of Sir John Tregoz, by his first wife, Mabel, daughter of Sir Fulk Fitzwarin.
