In 1745 Whitehead became the tutor of George Villiers, Viscount Villiers, son of William Villiers, 3rd Earl of Jersey, and took up his residence in London. There he produced two tragedies: "The Roman Father" and "Creusa, Queen of Athens". The plots of these tragedies are based the "Horace" (1640) of Pierre Corneille, and the "Ion" (c. 414–412 BC) of Euripides. He accompanied Lord Villiers and George Harcourt, Viscount Nuneham, son of Simon Harcourt, 1st Earl Harcourt on their Grand Tour between 1754 and 1756.
