Duckham was born in Blackheath, London, the second son of a Falmouth-born mechanical and civil engineer, Frederic Eliot Duckham (1841 - died 13 January 1918 in Blackheath), who had patented improvements in governors for marine engines and invented a 'Hydrostatic Weighing Machine'. His mother was Maud Mary McDougall (1849-1921), sister of John McDougall of the flour-making family, which had a mill at Millwall Dock. His older brother was Alexander Duckham, notable for the development of machine lubricants.
