William Pitt the Younger, who was facing difficulty in mustering support in parliament for his premiership. Henry ordered the six MPs under his control to support Pitt, helping Pitt gain enough votes in parliament to form a ministry. The Duke died in 1794 aged 73 in Westminster. Legacy The Duke is mainly known today as the creator of Clumber Park, his country seat in Nottinghamshire, and the dog breed the Clumber Spaniel, named after the estate. Clumber Park was begun in 1768 on the large estate the Duke had inherited from his uncle. Four thousand acres (16 square kilometres) of barren heath were landscaped into one of the most beautiful private parks in England, complete with a large man-made lake. The great mansion built there was demolished in 1938, but the park is today owned by the National Trust and is open to the public. He had also been a Bailiff on the board of the Bedford Level Corporation Fenland reclamation scheme from 1742 to 1764. The papers of the 2nd Duke are now held by Manuscripts and Special Collections at the University of Nottingham. Family life Before his wife's death at the age of 33, the Duke had four sons with her: George Pelham-Clinton, Lord Clinton (26 November 1745 – 19 August 1752) Henry Fiennes Pelham-Clinton, Earl of Lincoln (5 November 1750 – 18 October 1778), who married Lady Frances Seymour-Conway (4 December 1751 – 11 November 1820) on 21 May 1775 and had issue.
