Henry Hastings, 5th Earl of Huntingdon (24 April 1586 – 14 November 1643), was a prominent English nobleman and literary patron in England during the first half of the seventeenth century.

John Churchill, Marquess of Blandford (13 February 1686 – 20 February 1703) (sometimes called Charles Churchill) was a British nobleman. He was the heir apparent to the Dukedom of Marlborough – as the only surviving son of John Churchill, 1st Duke of Marlborough, an accomplished general, and Sarah Churchill, Duchess of Marlborough, a close friend of Queen Anne. Blandford died childless in 1703, and upon his father's death in 1722, the dukedom passed to his eldest sister, Lady Henrietta Godolphin (née Churchill).

Edgar Stuart, Duke of Cambridge (14 September 1667 – 8 June 1671) was the fourth son of James, Duke of York (later James II of England) and his first wife Anne Hyde. He was second in the line of succession to the English and Scottish thrones.

Charles was born on 4 July 1666 at St James's Palace. His godparents were his three-year-old brother James, Duke of Cambridge, his cousin James, Duke of Monmouth, and Emilia von Nassau, Countess of Ossory. He was designated Duke of Kendal and was to have been created Duke of Kendal, Earl of Wigmore, and Baron of Holdenby, but no patent was ever enrolled. He died at St James's Palace at the age of 10 months on 22 May 1667 and was buried in Westminster Abbey on 30 May 1667.
