Arthur Onslow, (1691-1768), speaker of the House of Commons. Onslow was a speaker of integrity in a corrupt age, and recognised the importance of distancing the chair from corruption. He established the impartiality of the speaker, and insisted on strict observance of procedure and practice, and introduced important administrative reforms of the House of Commons. In October 1720 Onslow married Anne (1703-1763), the daughter of John Bridges of Thames Ditton, Surrey, who was also the niece and heir of Henry Bridges of Ember Court. He bought Sandown Manor in 1741 and lived there until his death in 1768, when the estate passed to his son George Onslow, 1st earl of Onslow (1731-1814), who was also a politician. In June 1753 he married Henrietta (1731-1809) at Thames Ditton. She was a niece of the Duke of Newcastle-under-Lyne, who lived at Oatlands. They moved to Clandon Park, and his eldest son Tom succeeded him at Sandown.
