Street Directories - Chelsea 1864/5/6

[Evelina]

Hi does anyone have access to Street Directories for Chelsea 1864/5/6 or even know if they exist?  I am looking for my Great grandfather James Fergus's employers.  He was a Butler in 1865 and 1866 (when he died) and living at 7 Earl Street and although he was married his death was registered by W. Brown.  I do not know if this is the employer or another employee.   He does not appear on the 1861 census at this address so that does not help. By 1871 his widow and child have returned to Scotland so no help there either. Cheers Evelina
