William Clapham of London was a Citizen and Grocer (d 1688), who owned Cox Key, Fresh Wharf and Gaunt's Key as well as warehouses in Thames Street. The properties were left in tail to his son William Clapham (d 1730). By 1764 William Skrine had gained the reversionary interest. Skrine may have been distantly related to the younger William Clapham through Clapham's wife, Mary Lem.
