Sir Thomas Grey (30 November 1384 – 2 August 1415), of Castle Heaton near Norham,^[1] Northumberland, was one of the three conspirators in the Southampton Plot against King Henry V in 1415.

Family

Sir Thomas Grey, born 30 November 1384 in 'le Midyllgathouse’ at Alnwick Castle,^[2] seat of the Percys, Earls of Northumberland, came from a family long prominent among the nobility in the border region of Northumberland.^[3]

He was the eldest son and heir of Sir Thomas Grey (1359 - 26 November 1400) of Heton near Norham, Northumberland, by his wife, Joan Mowbray (d.1410), sister of Thomas de Mowbray, 1st Duke of Norfolk,^[4] and daughter of John de Mowbray, 4th Baron Mowbray (d. 17 June 1368), and Elizabeth de Segrave, daughter and heiress of John de Segrave, 4th Baron Segrave. Through his mother, a granddaughter of Margaret, Duchess of Norfolk (d.1399), Sir Thomas Grey was a descendant of King Edward I. His paternal grandparents were the soldier and chronicler Sir Thomas Grey of Heton, and Margaret, daughter and heiress of William de Pressene of Presson.^[5]

He had three brothers and a sister:^[6]

• John Grey, 1st Earl of Tankerville (d.1421), who married Joan de Cherleton, stepsister of Edmund Mortimer, 5th Earl of March.^[7]
• Sir Henry Grey of Ketteringham, Norfolk, who married Emme Appleyard.^[8]
• William Grey, Dean of York and Bishop of London (1426) (d.1436).^[9]
• Matilda Grey (1382–1451), who married Sir Robert Ogle (d. 12 August 1436) of Ogle, Northumberland, by whom she had issue.^[10]

A Soldier's Life

Grey's father, Sir Thomas Grey (1359-1400), and Sir Thomas Erpingham, were among those chosen allies of Henry Bolingbroke to witness the abdication of King Richard II in Westinster Hall on 29 September 1399.^[11]

Grey was only 16 years of age when he succeeded his father in 1400, and was shown great favour in the early years of the reign of Henry IV, including the grant of the wardship of his own inheritance while he was under age.^[11] By August 1404 he had been retained for life by Ralph Neville, 1st Earl of Westmorland, but by May 1408 was in the service of Henry, Prince of Wales.^[11]

Grey's part in the Southampton Plot was attributed by Grey himself to 'poverty and covetousness'.^[12] In 1412 Grey married his 12-year-old son and heir, Thomas Grey, to Isabel, the 3-year-old daughter of Richard of Conisburgh, 3rd Earl of Cambridge. As part of the marriage settlement, Grey acquired the lordship of Wark-in-Tyndale at a 'bargain price', which was nonetheless more than he could afford, leading Pugh to conclude that Grey was Cambridge's 'dupe', 'whose intrigues brought them both to disaster'.^[13]

Grey, Cambridge, and Henry Scrope, 3rd Baron Scrope of Masham, were the ringleaders of the failed Southampton Plot of 1415, which was a plot to assassinate King Henry V at Southampton before he sailed to France and to replace him with Edmund Mortimer, 5th Earl of March.^[14] On 31 July 1415 Mortimer revealed the plot to the King at Portchester Castle, near Portsmouth.^[15] The conspirators were promptly arrested and executed. Sir Thomas Grey was beheaded at the North Gate of Southampton on 2 August 1415.^[16]

The Southampton Plot is dramatized in Shakespeare's Henry V, and in the anonymous play, The History of Sir John Oldcastle.

Family

Sir Thomas Grey married, before 20 February 1408, Lady Alice Neville, the daughter of Ralph Neville, 1st Earl of Westmorland, by his first wife Margaret (d.1396), daughter of Hugh de Stafford, 2nd Earl of Stafford, by whom he had four sons and four or five daughters:^[17]

• Sir Thomas Grey (1404 – d. before 1426), who in 1412, at eight years of age, was betrothed to Isabel, then three years of age, only daughter of Richard of Conisburgh, 3rd Earl of Cambridge,^[18] and Anne Mortimer, they had one son.^[19]
• Sir Ralph Grey (d. 17 March 1442), who married Elizabeth, daughter of Henry FitzHugh, 3rd Baron FitzHugh, and Elizabeth Grey, and left issue.^[20]
• Sir John Grey.^[21]
• William Grey (d.1478), Chancellor of Oxford University, Bishop of Ely, and Lord High Treasurer.^[22]
• Eleanor who married Sir John Arundel.<ref name="R_II-257"/ ^[23]>
• Joan Grey, who married Sir John Salvin.^[21]
• Elizabeth Grey, who married firstly, Sir William Whitchester, and secondly, Sir Roger Widdrington.^[21]
• Margaret Grey, who married Gerard Widdrington.

Grey's widow, Alice, married Sir Gilbert Lancaster, by whom she had one son, Sir Gilbert Lancaster. Alice was still living on 22 August 1453.^[21]

The historian Pugh contents that "there was no plot in 1415 to assassinate Henry V and his three brothers and that heinous charge, by far the most sensational in the indictment, was fabricated to ensure that Cambridge, Gray and Scrope did not escape the death penalty as a well-deserved punishment for the various other offences that they undoubtedly had committed".
