Denzil Onslow (of Stoughton)

Denzil Onslow (c. 1698 – 15 November 1765) was a British politician. A member of the influential Onslow family of Surrey, he held a number of lucrative Government posts, and died owing a substantial sum to the Treasury through mismanagement of his accounts.

He was the son of Richard Onslow (d. 1719) and Sarah Manning, and grandson of Sir Henry Onslow, of Drungewick, who was a younger son of Sir Richard Onslow. His mother was Sarah, daughter of Thomas Calvert.^[1]

A member of a junior branch of the Onslow family, which held a powerful Parliamentary interest in Surrey, he married Anne Middleton, the daughter of his second cousin Anne and Thomas Middleton. They had two sons:^[1]

• Middleton Onslow (d. 1801)
• Capt. Richard Onslow (1734–aft. 1765)

Denzil succeeded his second cousin Richard Onslow in 1727 as receiver general of the Post Office when the latter wished to enter Parliament on the family interest at Guildford. Denzil, in turn, gave up the office when he, too, entered Parliament for Guildford in 1740 at a by-election, triggered when his nephew Richard succeeded to a peerage. Elected again in 1741, he was a consistent supporter of the Government, and was appointed in 1743 as Paymaster of the Works. He did not stand again at the election of 1747, as the Place Act 1742 made incompatible his seat on the Board of Works with a place in Parliament.^[1]

He was questioned over errors in his Post Office accounts in 1748, but remained paymaster until 1755.^[1] In 1753, he inherited Kevington Hall from his first cousin, Richard Manning.^[2] He became instead a commissioner of stamp duties until 1757, and then of the salt office until his death in 1765. In 1764, the Treasury was inquiring into his arrears as Paymaster of the Works, and he died owing over £1,500 to the Treasury, a debt still unsettled in 1783.^[1]
