His grandfather William was also a Member of Parliament and his great-grandfather Richard Osbaldeston had been Attorney General for Ireland. Through his grandmother Anne Wentworth he was related to the family of Thomas Wentworth, 1st Earl of Strafford, the formidable Lord Lieutenant of Ireland. He graduated MA from St John's College, Cambridge, in 1714, becoming a Fellow of Peterhouse, Cambridge. He was a chaplain to King George II of Great Britain, and tutor to King George III.
