mrs Cannon 15.3.1795 at King's / 22.3.1795 there / 14.11.1804 call on mrs Cannons / Cannon calls 24.1.1815
On 16.1.1791 Cannon contributed £50 (one of the largest donations) to the Socy of Const Info's subscription to relieve the French. Since Carbine also gave £50 these may have been joke names ( a rather dangerous political joke). A Mrs Cannon of Little Chelsea kept a seminary for young ladies (post-1800) (DNB J G H Jay 1770-1849). Edward Bacon Cannon attorney of Leicester Pl Soho voted Paull 1806 Burdett 1818. Cannons was a surname though far less frequent than Cannon, e.g. John Cannons was a victualler of Kent St Southwark Sun Fire 1785 and that was the closest I could find to 1804. Cannon in 1814 was very likely George Cannon DNB 1789-1854, who called on Shelley five days later (Mary Shelley's Journal).
Carbine also gave £50 in 1791.Louis Carbine launderer 6 New Broad St Golden Sq Sun F 1820
