In his diary (pages 20, 44, 139) George Marsh makes a number of references to Lord Viscount Weymouth between 1776 and 1779. During this time Lord Weymouth was an active member of the Cabinet in the government of Lord North (Frederick North, 2nd Earl of Guilford 1732-1792 ).
Lord Weymouth had succeeded his father as 3rd Viscount Weymouth in January 1751. Lord Weymouth was appointed Secretary of State for the Northern Department in January 1768. Before the close of 1768 he was transferred from the Northern to the Southern Department, but he resigned in December 1770 in the midst of the dispute with Spain over the possession of the Falkland Islands. In November 1775 Lord Weymouth returned to his former office of secretary for the Southern Department. In 1779 he undertook additional duties attached to the Northern Department for a few months but then resigned both positions in the autumn of that year. In 1789 he was created Marquess of Bath. His home was Longleat near Bath. He died in November 1796.
