The house of Charles Chubb (d.1804), blacksmith at Breamore, Hants, was licensed for Methodist meetings in 1768. His son Charles Chubb junior (1772-1846) was born on 16 January 1772, started a hardware business in Winchester, moved to Portsea in 1804 and to London in 1824. He remained staunchly loyal to WM and was known for his charitable giving. He died in Islington on 16 May 1846. In 1818 he and his brother Jeremiah Chubb (b. 1790) patented the detector lock which was virtually unpickable. With his son John Chubb (1815-1872) he developed a successful lock and safe business, with factories in Wolverhampton and London. In 1851 Chubbs made the cage in which the Koh-i-noor diamond was displayed at the Great Exhibition and John Chubb was awarded the Telford Silver Medal for his paper on locks presented to the Institute of Civil Engineers. He served on the WM Education and Missionary Committees, the management committee for Richmond College and the Committee of Privileges. He died at Brixton Rise, London on 30 October 1872.
By his first marriage (to Priscilla Withers) John Chubb had three sons, who became managing directors of the family firm when it became a private limited company in 1882: John Charles Chubb (1846-99), George Hayter Chubb (1848-1946) and Henry Withers Chubb (1857-1905). George Hayter Chubb married Sarah Vanner Early in 1870. He was created a knight in 1885, a baronet in 1890 and first Baron Hayter of Chiselhurst in 1927. He served on several connexional committees, was a governor, chairman of governors and treasurer of The Leys School and played a leading part in establishing Farringtons School. He helped the enterprising Herbert Jenkins found his publishing firm and became its chairman. It was largely through him that during World War I the WM Soldiers Homes were established. His son Charles Archibald Chubb, 2nd Baron Hayter (1871-1967) and his grandson George Charles Hayter Chubb, 3rd Baron, CBE, KCVO (1911-2003) were both educated at The Leys School. The latter was the last family member to serve as chairman of the company and oversaw a great expansion of its scope. The three brothers had a sister, Priscilla Jane Chubb, whose daughter Priscilla married William Guy Mewburn, son of William Mewburn junior.
