Jeacocke carried on the business of a baker in High Street, St. Giles's, London, and became a director of the Hand-in-Hand fire office, and a member of the Skinners' Company.
He frequently attended the Robin Hood debating society which held meetings in Butcher Row, Temple Bar.
At a time when Jeacocke was president, sitting in a large gilt chair, Goldsmith commented that nature had meant him for a Lord Chancellor; "No, no," whispered Derrick, "only for a Master of the Rolls".
[1] Jeacocke died on 7 January 1786, in Denmark Street, Soho, London.
He was author of A Vindication of the Moral Character of the Apostle Paul against the Charges of Hypocrisy and Insincerity brought by Lord Bolingbroke, Dr. Middleton, and others, London, 1765.
