Gurney was born at Keswick Old Hall, Norwich on 19 January 1775, the eldest son of Richard Gurney of
Keswick Hall, Norfolk, by his first wife, Agatha, daughter of
David Barclay of
Youngsbury, Hertfordshire; Hudson was born at what is now known as Keswick Old Hall, the original residence of the Norwich Gurney family. He was educated by his grandfather Barclay, by
Thomas Young, and by
John Hodgkin. He inherited a fortune from his father in 1811. In early life he travelled on the continent with his friend
George Hamilton-Gordon, 4th Earl of Aberdeen. Gurney was briefly M.P. for
Shaftesbury from 1812 to 1813, the election being voided on petition. In March 1816, he was elected M.P. for
Newtown, Isle of Wight, sitting in five successive parliaments until 1832. He served much on committees. He was appointed
High Sheriff of Norfolk for 1835–36. He was elected fellow of the
Society of Antiquaries on 12 March 1818, and was vice-president from 1822 to 1846. He contributed to the society many hundreds of pounds for the publication of Anglo-Saxon works. He was also a
Fellow of the Royal Society (elected 15 January 1818), a member of the
British Archæological Association from 1843, vice-president of the Norfolk and Norwich Archæological Society and a supporter of the
Norwich Museum and Literary Institute. Gurney lived at Keswick Old Hall and in St. James's Square, London, where he saw much society till the last twenty years of his life, when he suffered from ill-health. In 1817 he felt he built Keswick Hall, re-naming the original house Old Hall. On 9 November 1864 he died at Keswick Hall, and was buried in
Intwood churchyard, near Norwich. He was the head of the Norfolk family of the Gurneys, and his fortune was inherited mostly by
John Henry Gurney. Gurney is described as having a habit of questioning everything: "he seemed never to agree with you"; but he was kind, liberal, and hospitable. He married in 1809 Margaret (d. 1855), daughter of
Robert Barclay, M.P., of
Ury, Kincardineshire. They had no children. Gurney's portrait (when about 20) was painted by
Opie, and also, about 1840, by
Briggs. ==Works==
