Notes for Robert HAMPDEN TREVOR, 4TH BARON TREVOR OF BROMHAM, 1ST VISCOUNT HAMPDEN
Took name and arms of Hampden in compliance with will of John Hampden of Great Hampden Bucks.Ambassador to the Hague 1739. Jint Paymaster General of the Forces 1759.

He was the eldest son of the second marriage of Thomas Trevor, 1st Baron Trevor of Bromham, and studied at Queens College, Oxford, graduating in 1725 and then becoming 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 Horace 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.

IN 1750 he was appointed a commissioner of the Revenue in Ireland. He took the additional name of Hampden in 1754, on succeeding to the estates of that family, from John Hampden. In 1776, twelve years after he had succeeding his brother as Baron Trevor, he was created Viscount Hampden.

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 (1749–1824), died only three weeks after he had succeeded his brother Thomas as 3rd Viscount Hampden, the titles becoming extinct.

On the death of his brother Bishop Trevor in 1771 his eldest brother Robert inherited the Sussex estate. Robert was educated at Queen's College, Oxford, took his B.A. in 1725 and was elected fellow of All Souls in the same year. 'He was a good scholar and a collector of drawings and prints.' Several of his Latin poems 'Britannia,' 'Lathmon' and 'Villa Bromhamensis' were published as 'Poemata Hampdeniana' by his son John at Parma in 1792. Robert had been Secretary of the Legation at the Hague from 1734-9 and minister there from 1739-46. In 1746 he resigned and was appointed a Commissioner of the Revenue in Ireland, 1759, and Joint Postmaster-General, 1759-1765, offices which show that his adherence to the Whigs did not go unrewarded.

Robert's distant relative John Hampden, the last of his family, bequeathed all his Buckinghamshire estates to him and in 1776 when Robert was created a viscount he took the title of Viscount Hampden of Great and Little Hampden. According to Horace Walpole the title was obtained through the influence of Robert's son-in-law Henry, [12th] Earl of Suffolk. Robert married Constantia, the daughte of Peter Anthony de Huybert, Lord Van Kruyningen of Holland, and had two sons Thomas and John.

Thomas had been M.P. for Lewes in 1768 in the Duke of Newcastle's interest. He married firstly Catherine, the daughter of General David Graeme of Braco Castle, Perth, who died in 1804, and secondly Jane Maria, daughter of George Brown of Ellistoun but had no issue by either wife. Lord Hampden and his first wife were attacked in The Female Jockey Club (1794) 'but the most serious charge against him is his having left the Whigs on the outbreak of the French Revolution, and against her that she was languid and insipid and addicted to musical parties and cardplaying.' Lady Hampden's portrait by Gainsborough hangs in the gallery at Glynde Place.

Thomas died in 1824 and his brother John, who had been a diplomatist, British Minister at Munich, 1780, and at Turin, 1783-98, succeeded to the title only to die three weeks later, also without heirs.
