Sir William Humfreys, 1st Baronet (also spelled Humphreys; died 26 October 1735), was a British ironmonger and politician who sat in the House of Commons from 1715 to 1722. He was Lord Mayor of London for 1714–15 and a Director of the Bank of England between 1719 and 1730.
He was the only son of ironmonger Nathaniel Humfreys of Candlewick Street, London. His father was the second son of William Ap Humfrey, of Penrhyn, Montgomeryshire. He followed his father into the ironmongery trade of London, and was Master of the Worshipful Company of Ironmongers in 1705. He became an oilman and drysalter in Poultry, London, living afterwards in Bloomsbury Square.[1]
He married firstly Margaret Wintour, daughter of William Wintour of Dymock, Gloucestershire with whom he had a son, Orlando. She died on 19 August 1704, and was buried at St Mildred, Poultry. He married secondly, on 6 January 1705 at Knightsbridge Chapel, Ellen, the widow of Col. Robert Lancashire of London. He had no issue by his second wife, who died on 25 March 1732.
He died on 26 October 1735, and was buried on 6 November 1735 at St Mildred, Poultry. He was succeeded by his only son, Orlando, who married Ellen Lancashire, his stepmother's daughter by her first husband. Orlando died without surviving male issue on 14 June 1737, his only son (Robert) having died a few months before on 17 January; the baronetcy thus became extinct. His widow died on 3 April 1745.[1] In the complicated family circumstances Hever Castle was sold in 1749 to Timothy Waldo.[4]
