Fransom calls 30.9.1803 (at Norwich) / 4.7.1831 Fransom at John Martin's
John Fransham DNB 1730-1810. The name was very rarely spelt Fransom in Norfolk, e.g Daniel Fransom farmer of Hindringham 1864. In 1831 there were Fransoms in Kent, e.g. at Ospringe but the nearest I have found in London was Francis Fransham silversmith of St Luke Old St born 1789 Brook, Norfolk and buried 26.4.1849 Old St. All the other guests at Martin's that day were regulars there and all but one (Wheatsen) are identified in GD website and have entries in DNB
