found: Oxford DNB WWW site, Oct. 30, 2007(Hall, Sidney (1788/9?-1831), map maker and engraver; first appears in 1814 in partnership with Michael Thomson; by 1816 Hall had taken over Thomson's premises in Bury St., Bloomsbury, London, where he was to remain throughout his career; after Sidney Hall died in 1831, his wife, Selina Hall (1781/2-1853), continued the business; many maps signed S. Hall [after 1831] are undoubtedly her work or work done under her direction, although it was her husband's name that continued to appear on the t.p.'s of atlases as well as in contemporary directories; Sidney Hall's usual form was "Sidy. Hall"; d. 18 Feb. 1831, his age being given as 42)
