No 1 Congreve St is listed as being occupied by Samuel William Suffield, chemist, tea merchant etc in the 1829 directory. In the 1823 version it was another chemist. In 1829 there is also listed a William Suffield, bookseller,in Anne St, though no number is given. Possibly it was the same building. In the 1833, 1839, 1841 and 1845 directories Samuel is also at 1 Congreve St, though in 1841 he is listed as Samuel Wilson Suffield, and in 1845 address is given as 1 Congreve St ,Ann St, so in 1845 he definitely occupied both sides of the building. In 1849 no 1 Congreve st is coffee rooms and there is no Suffield nearby. There is uncertainty as to how accurate the dates of these early directories were, the survey possibly being several years earlier than publication date in some instances.
