Rev. Lord John Thynne (7 November 1798 – 9 February 1881) was an English aristocrat and Anglican cleric, who served for 45 years as Deputy Dean of Westminster.
Lord John was born in 1798, the third son of Thomas Thynne, 2nd Marquess of Bath (1765–1837) by his wife Hon. Isabella Elizabeth Byng, a daughter of George Byng, 4th Viscount Torrington.
He was educated at Eton College and St John's College, Cambridge, and was ordained by John Fisher, Bishop of Salisbury, in 1822. His first post was as curate of Corsley, a parish on his father's estate of Longleat, Wiltshire.[1] Next he served as rector simultaneously of Backwell, Street with Walton, and Kingston Deverill, all in Somerset and Wiltshire. In 1828 he was appointed a canon and subdean of Lincoln Cathedral, then became a Canon of Westminster Abbey in 1831. He became sub-dean of Westminster in 1835, later declining the deaneries of Westminster, Wells and Windsor. He lived at Ashburnham House near Westminster Abbey and assisted at the coronation of King William IV and Queen Adelaide, and later at the coronation of Queen Victoria in 1838. [2]
On 2 March 1824 at St James's Church, Piccadilly, he married Anna Constantia Beresford, a daughter of Rev. Charles Cobbe Beresford. She later built the first marine aquarium in Britain. By his wife he had the following issue:
He inherited the estate of Haynes Park, Bedfordshire, and the manor of Kilkhampton in Cornwall from his childless uncle, John Thynne, 3rd Baron Carteret (1772–1849). Stowe House in Kilkhampton had been the seat of his distant ancestor John Granville, 1st Earl of Bath (1628–1701), and had descended from him via the Cartaret family.
He died on 9 February 1881, and was buried at Haynes Park. His monument designed by Henry Hugh Armstead, a recumbent effigy within an arched recess, survives in the north choir aisle of Westminster Abbey.
