Henry Percy (born April 1564, died 5th November 1632) was the son of the eighth Earl of Northumberland and succeeded his father, who was murdered in the Tower, in 1585. Lord Northumberland was fined and imprisoned in the Tower in consequence of an alleged complicity in the Gunpowder Plot. In 1593 he was made a Knight of the Garter, and in 1603 he was Captain of the Corps of Gentlemen Pensioners. Northumberland was in distant remainder to the Crown of England, and at one time it was probable that his claims might be strengthened by a marriage with Lady Arabella Stuart, niece of Lord Darnley, and great-granddaughter of Margaret, elder daughter of Henry VII., but the negotiation came to nothing. The Earl was fond of scientific pursuits and was known as "The Wizard Earl," and was a great smoker. The badge of the silver crescent was used by the Percy family generally and not exclusively by any particular member of it.

[PONTIFICALE. Lansdowne MS. 451.] William Fitzmaurice Petty (born 1737, died 7th May 1805) was the son of John, Earl of Shelburne. He was educated at Oxford, and then entered the army, and fought at Campen and at Minden, eventually becoming a general officer. He represented High Wycombe in Parliament. In 1761, on the death of his father, William Petty became Earl of Shelburne, and quickly made his mark in the House of Lords, and became head of the Board of Trade. In 1766 he became a Secretary of State for the Southern Department. On the death of Lord Rockingham in 1782, Lord Shelburne succeeded as Premier, and held this position until 1783. In 1784 Lord Shelburne was created Marquis of Lansdowne, and he spent the remainder of his life at his beautiful Wiltshire seat of Bowood. About 1765 he began collecting books, particularly those concerning history and politics. Among the books collected by Lord Shelburne were several which had belonged to Sir Julius Cæsar, and also many of Lord Burghley's. Lord Lansdowne's manuscripts were acquired for the British Museum by purchase after his death.
