Proctor, William Grosvenor, London, cm and u (1820–26). Initially probably the manager for Robert & Henry Chipchase but by 1809 had become a partner in the business which traded as Chipchase & Proctor from an address at 27 Albemarle St. The Chipchases had withdrawn from the business by 1818 when it was trading as Proctor & Chadley. William Proctor did not maintain this business connection for long, however, and by 9 October 1820 had broken away and was trading on his own behalf from an address at 29 Argyle St, Oxford St. The Albemarle St premises continued to be occupied by Robert & George Chadley. The move to Argyle St probably resulted in a scaling down in the size of the enterprise, for although Proctor took out insurance cover of £4,500 on the new premises only £1,000 was for utensils and stock. In October 1822 the corresponding figures were £5,900 and again £1,000. [D; GL, Sun MS vol. 483, ref. 970952; vol. 493, ref. 997314]
