John Peppercorn (1844-3 November 1915) was a businessman and local politician active in south east London. Born in Deptford, he was one of several sons of Joseph Peppercorn, a Bedfordshire born grocer and cheese monger and his wife Ann Howard née Down from Devon. After serving an apprenticeship, John set up in business as a grocer by 1870, when he married Florence L Poulton from Torquay. His business became a limited company, Peppercorn Brothers Limited of Greenwich and Deptford, and he retired to Lee, where he died aged 70.
