Some interesting entries from Bromley directories:-
1871 George Whiffin at 7 Walter's Yard, Bromley High St
1876 ditto
1887 Wm Larkin at 2 Mooreland Rd, Farwig
Several William Johnsons, but not at Walter's Yard
1889 Mrs Larkin at 3 Morum's Cottages, Farwig
William Johnson at 10 Sharpe's Cottages, Walter's Yard
1891 Mrs Larkin at 31 Mooreland Rd
William Johnson at 10 Sharpe's Cottages, Walter's Yard
1892 ditto
1896 Mrs Larkin not found (left Bromley, or this world?)
F Johnson at 10 Sharpe's Cottages, Walter's Yard
1900 ditto
1903 Frederick Johnson at 12 Sharpe's Cottages, Walter's Yard
1905 Frederick James Johnson at 12 Sharpe's Cottages, Walter's Yard
Charles Edwards, bootmaker, 19 Bromley High St. Other Charles Edwardses elsewhere.
1909 No longer at Walter's Yard
Thereafter, the commonness of Johnson and Edwards surnames make it hard to be sure of the right person, and Whiffen was also a common name in NW Kent at one time. Bromley Local Studies has more directories for intermediate years *, which I will look at next time I'm there. But Dee should really visit if possible. If not, they will answer quick questions free by email. I will try to help if possible, but they're about to cut opening hours, which may reduce my future helpfulness.

* The above, and other, directories were online at one time, but the link I have no longer works and I can't find them elsewhere on the Council website. I'm glad I grabbed them when I did
