Robert Hampden-Trevor, 1st Viscount Hampden

He was the eldest son of the second marriage of his father Thomas Trevor, 1st Baron Trevor to Anne Bernard, née Weldon.

He studied at Queens College, Oxford, graduated in 1725 and then became a fellow of All Souls College, Oxford. In 1729 he was appointed as a clerk in the Secretary of State's office. In 1734 he went to the United Provinces as secretary to the embassy under Horatio Walpole. He succeeded as head of the embassy in 1739, initially as Envoy-Extraordinary, and from 1741 as Minister-Plenipotentiary. During this time he maintained a regular correspondence with Horace Walpole.[1]

IN 1750 he was appointed a Commissioner of the Revenue in Ireland. He took the additional surname of Hampden in 1754, on succeeding to the estates of his relative John Hampden. Twelve years after he had succeeding his brother as Baron Trevor, he was created, on 14 June 1776, Viscount Hampden, of Great and Little Hampden in the County of Buckingham.[1][2]

From 1759 to 1765 he was joint Postmaster General. He wrote some Latin poems which were published at Parma in 1792 as Poemata Hampdeniana. His second son, John Hampden-Trevor, 3rd Viscount Hampden (1749–1824), died only three weeks after he had succeeded his elder brother Thomas Hampden-Trevor, 2nd Viscount Hampden, when the titles became extinct.[1]
