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.

Along with Harold Woodall he formed a company, Woodall-Duckham, which developed the continuous vertical retort for manufacturing gas from coal.
He married Maud Peppercorn, daughter of Arthur Douglas Peppercorn, and they had three children.
