Sir John Lade, 2nd Baronet (1 August 1759 – 10 February 1838) was a prominent member of
Regency society, notable as an owner and breeder of
racehorses, as an accomplished
driver, associated with
Samuel Johnson's circle, and one of
George IV's closest friends. At the time he caused some sensation both because of the extent of his debts and the scandal attached to his marriage to his wife
Letitia, a woman who was generally supposed to have been previously the mistress of both the executed
highwayman John Rann and the Prince Regent's brother, the
Duke of York.
