Think I've found the confectioners at 177 :
1862 it was not a confectioners
1868-73 Vale James, confectioner (listed as no 117 as numbering changed between 1873-76)
1876 Arthars Benjamin, confectioner
1878 Whately, George , confectioner
1879 Whateley George & Miss Ellen confectioners
1889 Avery Samuel Charles, confectioner. Not listed 1883 or after, though that doesn't necessarily mean he wasn't there as there was no-one at all listed at 177 (as opposed to 177A) in 1883-1888.
