Another thought......
In 1851 I found people living at 4, 5 and 8 Percy Passage.
At #4 we had Samuel (cheesemonger) and Thomas Knight (Tailor) with possibly their younger brother, Charles and in another room, Samuel ?, a shoemaker.
#5 Margaret Discomb, a servant
#8 Stephen Bland, a cutler
The next "street" enumerated is Bedford Passage. Prior to PP is Pitt Street... I can't spot either on maps.
I am wondering if the shops were downstairs and people roomed upstairs as I find Stephen Bland still in PP in 1841 along with other families. Unfortunately there are no house numbers.
