Dunch was the only son of Hungerford Dunch MP of Little Wittenham and Down Ampney and his wife Catherine Oxton, daughter of William Oxton of Hertfordshire. He was born in Little Jermyn Street, London, 14 December 1657, and baptised 1 January 1658. The freedom of the boroughWallingford was conferred on him on 17 October 1695, and he was at one time proposed as its high steward, but was defeated by Lord Abingdon, who polled fifteen votes to his six. On 2 May 1702 Dunch married Elizabeth Godfrey, one of the maids of honour to the queen, and one of the two daughters and coheiresses of Colonel Charles Godfrey, by Arabella Churchill, sister to the Duke of Marlborough. Her elder sister Charlotte, married Hugh Boscawen, afterwards Lord Falmouth.
Political career
Dunch joined heartily in the Glorious Revolution of 1688, and seems to have been a Whig throughout life. He was returned unopposed as Member of Parliament for the borough of Cricklade at the two elections in January and November 1701 but was defeated in a contest in July 1702. He was re-elected MP for Cricklade in the general elections of 1705, 1708 and 1710. At the 1713 general election he was returned unopposed as MP for Boroughbridge in Yorkshire. He was elected MP for Wallingford, a constituency which several of his ancestors had served in parliament at the 1715 general election and sat until his death four years later. It was rumoured in June 1702 that Dunch would be created a baron of England. Gossip also asserted in April 1704 that his father-in-law Colonel Charles Godfrey would become Cofferer of the Household and that Dunch would succeed Godfrey as Master of the Jewel Office. A third rumour, in 1708, was that Dunch would be made Comptroller of the Household. In fact the reward for his services was the position of Master of the Household to Queen Anne on 6 October 1708. When the comptrollership fell vacant on Sir Thomas Felton's death, in March 1709, Dunch tried for it in vain. He was deprived of the mastership in 1710, but was reappointed on 9 October 1714. Dunch was a member of the Kit-Kat Club, a dining and gathering point for Whigs supporters and as was the custom of the club his portrait was duly painted and engraved. He also had a reputation as a gambler and bon-vivant and is said to have clipped his fortunes by his gambling. Dunch died on 31 May 1719 and was buried in the family vault at Little Wittenham Church on 4 June, near Wallingford, in Oxfordshire, in the village where the family had had their seat for over 170 years.
Family
Many of Edmund's forebears had been parliamentarians, particularly representing Wallingford. William Dunch, auditor to the Mint for Henry VIII and Edward IV, represented Wallingford, and was High Sheriff of Berkshire. It was William who bought the manor of Little Wittenham in 1552, which was the family seat. His son, Sir Edmund Dunch, represented Wallingford in 1571 and was High Sheriff of Berkshire. His son Sir William Dunch represented Wallingford in 1603. He married Mary Cromwell in 1599, the daughter of Sir Henry Cromwell and aunt to Oliver Cromwell. It is believed that Mother Dunch's Buttocks, the variant name for the two rounded local hills Wittenham Clumps, is associated with her. William's brother Samuel represented Wallingford in 1620. William's son, Edmund, was Governor of Wallingford Castle, and later became Baron Burnell of East Wittenham, though he lost this title at the Restoration. He too represented Wallingford in 1627 and 1640, and was High Sheriff of Berkshire. Edmund's son Hungerford Dunch was returned for Wallingford in 1660 but elected to serve for Cricklade. Hungerford's son was this Edmund Dunch. Dunch had no sons, and was the last Dunch to represent Wallingford. With his death, the male line of this branch of the Dunch family became extinct. He had cut off the entail of the property and left it to his four daughters.
Arabella married on 6 February 1725 Yorkshire politician Edward Thompson. Her fate is told by Lord Hervey, in his Memoirs of the Reign of George II, ii. 346. According to this chronicler she had two children by Sir George Oxenden, and on his account was separated from her husband, and died in childbirth. An elegy to Mrs. Thompson was written by Lady Mary Wortley Montagu, and is printed in her 'Letters', ii. 484–5.
Dunch was first cousin twice removed of Oliver Cromwell. His wife, who was one of the beauties commemorated in the Kit-Cat Club verses, was half-sister to the illegitimate children of James II.
