No record of apprenticeship or freedom. Heal records William Burwash, watchcasemaker, at 45 Red Lion Street, Clerkenwell, from 1782-1804, for whom two incuse marks are entered in 1802 and 1803 at 3 Red Lion Street (Section V). It would seem very likely that he is the William Burwash of St.Stephen's, Wallbrook, married at that church, 7 November 1781, to Elizabeth Salt of St. John's, Clerkenwell, and that they may be the parents of William Burwash of this entry. First mark entered in partnership with Richard Sibley, 7 October 1705. Address: 14 Bartholomew Close. Second mark, alone, incuse, 6 July 1812. Third mark, (two sizes), 10 August 1812. Fourth mark, 23 April 1813, all at the same address. His son George apprenticed to Richard Sibley 1 January 1806, and another son William to William Chawner 6 November 1816, who had married Mary Burwashearlier that year.
