William Carey, of Aldenham, in Hertfordshire (  1500 – 22 June 1528) was a courtier and favourite of King Henry VIII of England.
 He served the king as a Gentleman of the Privy chamber, and Esquire of the Body to the King.
 His wife, Mary Boleyn, is known to history as a mistress of King Henry VIII and the eldest sister of Henry's second wife, Anne Boleyn.
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.
Grimston Manor was a manor house in Norfolk, England.
 In 1524, it was given to George Boleyn, the first grant King Henry VIII made to Boleyn.
 It is assumed that this was given on the wedding of George to Jane Parker.
 Henry VIII was around this time involved in a relationship with George's sister, Mary, and within two years would be pursuing George's other sister, Anne, who became Henry VIII's second wife.

Mary Arundell (died 20 or 21 October 1557), was the only child of Sir John Arundell (1474 – 1545) of Lanherne, Cornwall, by his second wife, Katherine Grenville.
 She was a gentlewoman at court in the reign of King Henry VIII, serving two of Henry VIII's Queens, and the King's daughter, Princess Mary.
 She was traditionally believed to have been "the erudite Mary Arundell", the supposed translator of verses now known to have been the work of her stepdaughter, Mary FitzAlan, later the first wife of Thomas Howard, 4th Duke of Norfolk.
( 1501 – 19 May 1536) was Queen of England from 1533 to 1536 as the second wife of King Henry VIII.
 Henry's marriage to her, and her subsequent execution by beheading, made her a key figure in the political and religious upheaval that was the start of the English Reformation.
Sir Francis Weston KB (1511 – 17 May 1536) was a gentleman of the Privy Chamber at the court of King Henry VIII of England.
 He became a friend of Henry VIII and was accused of high treason and adultery with Anne Boleyn, the king's second wife.
 Weston was condemned to death, together with George Boleyn, Viscount Rochford, Henry Norris, William Brereton and Mark Smeaton.
 They were all executed on 17 May 1536, two days before the Queen.
Sir John Port (c.1472 – c. 14 March 1540), judge, was the son of Henry Port of Chester.
 He was involved in the trials of Sir Thomas More, John Fisher and Anne Boleyn.
Elizabeth Cheney (April 1422 – 25 September 1473) was a member of the English gentry, who, by dint of her two marriages, was the great-grandmother of Anne Boleyn, Jane Seymour, and Catherine Howard, three of the wives of King Henry VIII of England, thus making her great-great-grandmother to King Edward VI, the son of Henry VIII and Jane Seymour, and Elizabeth I, the daughter of Henry VIII and Anne Boleyn.
 Her first husband was Sir Frederick Tilney, and her second husband was Sir John Say, Speaker of the House of Commons.
 She produced a total of eight children from both marriages.
Catherine Brandon, Duchess of Suffolk, "suo jure" 12th Baroness Willoughby de Eresby (22 March 1519 – 19 September 1580), was an English noblewoman living at the courts of King Henry VIII, King Edward VI and Queen Elizabeth I.
 She was the fourth wife of Charles Brandon, 1st Duke of Suffolk, who acted as her legal guardian during his third marriage to Henry VIII's sister Mary.
 Her second husband was Richard Bertie, a member of her household.
 Following Charles Brandon's death in 1545, it was rumoured that King Henry had considered marrying Catherine as his seventh wife, while he was still married to his sixth wife, Catherine Parr, who was Catherine's close friend.
