The first victim of the “Tyburn Tree” was Dr John Story, a Roman Catholic who refused to recognize Elizabeth I. Among the more notable individuals suspended from the “Tree” in the following centuries were John Bradshaw, Henry Ireton and Oliver Cromwell, who were already dead but were disinterred and hanged at Tyburn in January 1661 on the orders of Charles II in an act of posthumous revenge for their part in the beheading of his father.
Wikipedia, such a great source of interesting information.
