Prance was born in Bideford in Devon in 1889, one of five children of Deera Lock née Hollway (1861–1952) and Captain Fredrick William Prance (1859–1939) who was the owner and skipper of the fishing trawler 'Deera' (named after his wife), which operated out of the quayside in Bideford.
[3] Between the wars his works were published in such periodicals as The Humorist, London Opinion, Punch and Tatler.
After the War Prance illustrated the Lone Pine series of books for children by Malcolm Saville.
After briefly living in Hampstead in 1952 he bought West Campfield Place on Leith Hill in Surrey and here he established a new family home.
In 1998 the Gallery held a retrospective exhibition of Prance's work arranged by his son Christopher, who was living in the town.
