The Fitzwilliams were the heads of the Whig interest at Peterborough, holding the politically important office of custos rotulorum, or lord lieutenant, of the city, which they represented in most Parliaments from the mid-17th century till they became English peers in 1742. Returned for Peterborough in 1710, Fitzwilliam after 1715 voted consistently with the Government, speaking for them in a debate on foreign affairs, 8 Mar. 1727. His sudden death of a malignant fever, 28 Aug. 1728, was described as ‘a terrible blow’ to the government interest at Peterborough.1Thos. Gibson to Jos. Banks, 30 Aug. 1728, Letters and Pprs.
