List of Famous people with last name Onslow

Arthur George Onslow, 3rd Earl of Onslow was a British peer. He was the eldest child of the 2nd Earl and his wife Arabella Mainwaring-Ellerker.

Lieutenant-General Richard Onslow was a British Army officer and politician. After the death of their parents, his older brother Arthur bought him a captain's commission in the British Army. He first saw action in the Anglo-Spanish War in 1727, after which he was returned to Parliament for the family borough of Guildford. His political contributions were negligible in comparison to his brother, and he continued to serve as a career officer, holding commands in the War of the Austrian Succession at Dettingen and Fontenoy. In 1759, he was appointed Governor of Plymouth and commander of the Western District, and died as a lieutenant-general the following year while presiding over two prominent courts-martial.
