Michael's father was of English and Irish heritage, while his mother was English.
Michael Caine was born Maurice Joseph Micklewhite Jr. on 14 March 1933, in London, United Kingdom; the son of Maurice Joseph Micklewhite Sr., a fish market porter, and Ellen Frances Marie Burchell, a cook and charwoman. Caine had an elder maternal half-brother named David William Burchell, and a younger full brother, Stanley Micklewhite.
Michael grew up in Southwark, London, and during the Second World War, he was evacuated to North Runcton near King's Lynn in Norfolk. After the war, his father was demobilised, and the family were rehoused by the council in Marshall Gardens at the Elephant and Castle in a prefabricated house made in Canada, as much of London's housing stock had been damaged during the Blitz in 1940–1941.
