Question: Who was the father of the King of England under whom William Thomas was a clerk of the Privy Council?

full_context: Document 1: William Thomas (bishop): William Thomas (2 February 1613 – 25 June 1689) was a Welsh Anglican bishop. He was the Bishop of St David's and later the Bishop of Worcester.
Document 2: William Fitzwilliam (died 1559): Sir William FitzWilliam (1506 – 3 October 1559), of Windsor, Berkshire, was an Irish courtier and Member of Parliament in England. He was Chief Gentleman of the Privy Chamber to Edward VI of England; Deputy Chancellor of Ireland; Lieutenant of Windsor Castle; Keeper of Windsor Great Park and Lord Lieutenant of Berkshire.
Document 3: Thomas More: Sir Thomas More ( ; 7 February 14786 July 1535), venerated by Roman Catholics as Saint Thomas More, was an English lawyer, social philosopher, author, statesman and noted Renaissance humanist. He was also a councillor to Henry VIII, and Lord High Chancellor of England from October 1529 to 16 May 1532. He wrote "Utopia", published in 1516, about the political system of an imaginary ideal island nation.
Document 4: Thomas Walsingham (literary patron): Sir Thomas Walsingham (c. 1561 – 11 August 1630) was a courtier to Queen Elizabeth I and literary patron to such poets as Thomas Watson, Thomas Nashe, George Chapman and Christopher Marlowe. He was related to Elizabeth's spymaster Francis Walsingham and the employer of Marlowe's murderer Ingram Frizer. This connection is one of the reasons offered for suggesting that Marlowe's death may have been linked with intelligence work, and not a dispute over a bill for food and accommodation, as in the coroner's verdict.
Document 5: Robert and Thomas Wintour: Robert Wintour (1568 – 30 January 1606) and Thomas Wintour (1571 or 1572 – 31 January 1606), also spelt Winter, were members of the Gunpowder Plot, a failed conspiracy to assassinate King James I. Brothers, they were related to other conspirators, such as their cousin, Robert Catesby, and a half-brother, John Wintour, also joined them following the plot's failure. Thomas was an intelligent and educated man, fluent in several languages and trained as a lawyer, but chose instead to become a soldier, fighting for England in the Low Countries, France, and possibly in Central Europe. By 1600, however, he changed his mind and became a fervent Catholic. On several occasions he travelled to the continent and entreated Spain on behalf of England's oppressed Catholics, and suggested that with Spanish support a Catholic rebellion was likely.
Document 6: William Thomas (scholar): William Thomas (died 18 May 1554), a Welshman from Llanigon, Brecknockshire, was a scholar of Italian and Italian history and a clerk of the Privy Council under Edward VI. Thomas was executed for treason after the collapse of Wyatt's Rebellion under Mary I.
Document 7: Edward V of England: Edward V (2 November 1470 – ) was King of England from his father Edward IV's death on 9 April 1483 until 26 June of the same year. He was never crowned, and his 78-day reign was dominated by the influence of his uncle and Lord Protector, Richard, Duke of Gloucester, who succeeded him as Richard III on 26 June 1483; this was confirmed by the Act entitled Titulus Regius, which denounced any further claims through his father's heirs.
Document 8: The Death of Queen Jane: "The Death of Queen Jane" is an English ballad that describes the events surrounding the death of a Queen Jane. It is catalogued by Francis James Child as Child #170. Some of the versions given are Scottish, in which the queen's name is Jeanie or Jeany. Due to the close correspondence of names and events, it is often thought that the queen in question is Jane Seymour, the third wife of Henry VIII of England, but this cannot be confirmed. Historically, Jane Seymour gave birth to a son who became Edward VI of England on October 12, 1537. The birth was difficult but natural. She died twelve days later of infection resulting from the birth.
Document 9: Thomas de Courtenay, 5th/13th Earl of Devon: Thomas Courtenay, 5th/13th Earl of Devon (1414–1458) was an English nobleman who was involved in the Wars of the Roses. His seat was Colcombe Castle, near Colyton, Devon, and later the principal historic family seat of Tiverton Castle after his mother's death. Much of his life was spent in armed territorial struggle against his near-neighbour in Devon Sir William Bonville of Shute, Devon, at a time when central control over the provinces was weak. He had been married off as an infant to Margaret Beaufort, granddaughter of John of Gaunt, Duke of Lancaster, and started his career an adherent to the Lancastrian Beaufort party. On the demise of the Beaufort party he abandoned it in favour of the Duke of York. When York sought the support of Courtenay's arch-enemy Bonville, Courtenay fell out of favour with York. The Wars of the Roses led to the deaths and executions of all three of his sons, successively 6th, 7th, and 8th Earls of Devon, and the eventual attainder of his titles and forfeiture of his lands. The Earldom was however revived in 1485 for his distant cousin Sir Edward Courtenay, KG, (d. 1509), third in descent from his great-uncle. The ordinal number given to the early Courtenay Earls of Devon depends on whether the earldom is deemed a new creation by the letters patent granted 22 February 1334/5 or whether it is deemed a restitution of the old dignity of the de Redvers family. Authorities differ in their opinions, and thus alternative ordinal numbers exist, given here.
Document 10: Anne Seymour, Duchess of Somerset: Anne Seymour, Duchess of Somerset (née Stanhope) (c.1497 – 16 April 1587) was the second wife of Edward Seymour, 1st Duke of Somerset (c.1500–1552), who held the office of Lord Protector during the first part of the reign of his nephew King Edward VI, through whom Anne was briefly the most powerful woman in England. During her husband's time as Lord Protector she claimed precedence over the dowager queen Catherine.
Document 11: Henry FitzRoy, 1st Duke of Richmond and Somerset: Henry FitzRoy, 1st Duke of Richmond and Somerset (15 June 1519 – 23 July 1536), was the son of King Henry VIII of England and his mistress, Elizabeth Blount, and the only illegitimate offspring whom Henry VIII acknowledged. He was the younger half-brother of Queen Mary I, as well as the older half-brother of Queen Elizabeth I and King Edward VI. Through his mother he was the elder half-brother of the 4th Baroness Tailboys of Kyme and of the 2nd and 3rd Baron Tailboys of Kyme.
Document 12: Edward IV of England: Edward IV (28 April 1442 – 9 April 1483) was the King of England from 4 March 1461 to 3 October 1470, and again from 11 April 1471 until his death in 1483. He was the first Yorkist King of England. The first half of his rule was marred by the violence associated with the Wars of the Roses, but he overcame the Lancastrian challenge to the throne at Tewkesbury in 1471 to reign in peace until his sudden death. Before becoming king, he was 4th Duke of York, 7th Earl of March, 5th Earl of Cambridge and 9th Earl of Ulster. He was also the 65th Knight of the Order of the Golden Fleece.
Document 13: Lady Jane Seymour: Lady Jane Seymour (c.1541 – 19 March 1561) was an influential writer during the sixteenth century in England, along with her sisters, Lady Margaret Seymour and Anne Seymour, Countess of Warwick. Their brother was Edward Seymour, 1st Earl of Hertford. They were the children of Edward Seymour, 1st Duke of Somerset, who from 1547 was the Lord Protector of England after the death of King Henry VIII and during the minority of Jane's first cousin, King Edward VI. She was baptised 22 February 1541, and her godparents were Thomas Cromwell (the King's chief minister), Lady Mary (the King's daughter, at the time declared illegitimate but later to become queen) and Katherine Howard, the fifth wife of Henry VIII, and queen at the time. Jane was thus the niece of Henry VIII's third wife, Queen Jane, whom she was probably named after. She was the sole witness to the secret marriage of her brother Edward to Lady Catherine Grey (a potential heir to Queen Elizabeth I) in 1560. She died a year later, aged 20, probably of tuberculosis.
Document 14: Edward VI of England: Edward VI (12 October 1537 – 6 July 1553) was King of England and Ireland from 28 January 1547 until his death. He was crowned on 20 February at the age of nine. The son of Henry VIII and Jane Seymour, Edward was England's first monarch to be raised as a Protestant. During his reign, the realm was governed by a Regency Council because he never reached his majority. The Council was first led by his uncle Edward Seymour, 1st Duke of Somerset (1547–1549), and then by John Dudley, 1st Earl of Warwick, from 1551 Duke of Northumberland.
Document 15: Thomas Cromwell: Thomas Cromwell, 1st Earl of Essex ( or ; 1485 – 28 July 1540) was an English lawyer and statesman who served as chief minister to King Henry VIII of England from 1532 to 1540.
