The arms are those of Onslow, probably for George Onslow, born in 1731. He was the son of Arthur Onslow, the celebrated Speaker of the House of Commons, who was responsible for establishing much of the parliamentary procedure in use today. George Onslow married in 1753 Henrietta, daughter of Sir John Shelley, and two years later entered Parliament. He enjoyed a moderately successful political career, but he "was totally lacking in the disinterested integrity which characterize the Speaker. Throughout the forty years he was in office George Onslow repeatedly ingratiated himself with those in power at the expense of his principles" (Pamela, Countess of Onslow, "The Onslow Family" in Clandon Park, The National Trust, 1993).
