Howard held offices at court under four monarchs, Henry VIII, Edward VI, Mary I, and Elizabeth I, most notably the office of Master of the Armoury, and undertook several diplomatic missions.  A masque written by Howard was produced at court during the reign of Edward VI, and he is mentioned by name in the Langham letter, which describes the Earl of Leicester's entertainment of Queen Elizabeth at Kenilworth Castle in July 1575. Charles Howard was a gentleman at the court of Henry VIII of England.  He was the second son of Lord Edmund Howard and the elder brother of Sir George Howard.  As a scion of the mighty Howard family, his uncle, Thomas Howard, 3rd Duke of Norfolk was able to find him a position at court.  Charles' fortunes improved in 1540, when his sister, Catherine Howard became the King's fifth wife.  Charles went on to create a mesalliance with the King's niece, Margaret Douglas, the daughter of Henry's sister, Margaret Tudor, queen dowager of Scotland.

Queen Elizabeth I had ascended the throne at the age of 25 upon the death of her half-sister, Queen Mary I, on 17 November 1558.  Mary had reversed the Protestant Reformation which had been started by her two predecessors, so this was the last British coronation to be conducted under the authority of the Roman Catholic Church.  Historians view Elizabeth's coronation as a statement of her intention restore England to Protestantism, but to allow the continuation of some Catholic customs, a compromise known as the Elizabethan Settlement.

Mary is best known for her aggressive and bloody pursuit of the restoration of Roman Catholicism in England and Ireland in an attempt to reverse the English Reformation of her father, Henry VIII. Sir George John Robert Murray (27 September 1863 – 18 February 1942) was a judge from 2 April 1913 until 18 February 1942 on the Supreme Court of South Australia, which is the highest ranking court in the Australian State of South Australia.  He was Chief Judge from 20 January 1916 until 18 February 1942. Elizabeth I (7 September 1533 – 24 March 1603) was Queen of England and Ireland from 17 November 1558 until her death.  Sometimes called The Virgin Queen, Gloriana or Good Queen Bess, Elizabeth was the last monarch of the House of Tudor. Anne Brooke, Baroness Cobham, born Anne Braye (21 March 1501 – 1 November 1558), was the wife of Sir George Brooke, 9th Baron Cobham.  She was the attendant horsewoman at Anne Boleyn's coronation as Queen Consort on 1 June 1533, and she was allegedly one of the first accusers of Queen Anne in 1536.  Anne Braye was Baroness Cobham from 1529 until her death in 1558. Sir George Paulet (1553–1608), also known as Pawlet or Powlet, was a son of John Paulet, 2nd Marquess of Winchester or of Sir George Paulet (died 1558) of Crondall, Hampshire, brother of William Paulet, 1st Marquess of Winchester, and his third wife, Elizabeth, daughter of William Windsor, 2nd Baron Windsor.  Paulet was educated at Eton, 1564–72, and at King's College, Cambridge, 1572-5.  He was an English soldier, administrator, and governor of Derry who was killed by the followers of Sir Cahir O'Dogherty during O'Doherty's Rebellion.  After his death, Paulet's command at Derry was burned to the ground by the rebels.  Paulet was knighted in 1607.
