Former slave and businessman. Born in Senegal, (his birth year is approximate). At the age of about six, he was bought and taken to England, where he was presented as a servant to Sir John Phillipps of Norbiton though it seems they treated him more as a member of the family. He took his surname from Picton Castle, Phillips' country estate.
When Lady Philipps died, Picton received a legacy of £100 and set up business as a coal merchant in nearby Kingston. As Surrey Council report "In 1816 he bought a large cottage in Thames Ditton for the astonishing sum of £400, far above his inheritance, showing he had become a wealthy businessman." He was probably the richest of the thousands of black people in Britain at the time. Surrey also report "Cesar was never active in the abolitionist movement".
