Charles Upfold served his apprenticeship as a soap maker with John Knight & Co. at their Wapping soapworks in London, just across the river from the parishes where Charles's father resided and worked.
Charles appears on the UK 1851 Census Return, with his parents and married sister Eliza at 11 Brandon Street, parish of St.Mary Newington, London, (then in Surrey), where he is described as a "soap maker".
