“ Colley Cibber’s son, Theophilus Cibber (1703–1758) , also an actor and playwright, was born on the 26th of November 1703. In 1734 he was acting-manager at the Haymarket, and he subsequently played at Drury Lane, Lincoln’s Inn Fields and Covent Garden. His best impersonation was as Pistol, but he also distinguished himself in some of the fine-gentleman parts affected by his father. He was one of the ringleaders in the intrigues against John Highmore, who had bought a share in the patent of Drury Lane from Colley Cibber. ”
