In 1660 Monck obtained from the king the extraordinary warrant promising that should his issue fail in the male line his new title Duke of Albemarle be reverted to his first cousin and colleague in the success of the Restoration, John Granville, 1st Earl of Bath. Monck's son did indeed die childless in 1688, but no claim was made to the dukedom by the Granvilles of the new king, William III. And in 1697 the King conferred the title, as an earldom, on his favourite Arnold Joost van Keppel.
