A question for the OP:
Who was your ancestor, what was his occupation, and what is the evidence that links him to 32 London Road?
I have just been trawling through newspaper references to 32 London Road in the 1870s, of which there are many. In accordance with an earlier find in a directory, it is clear that the premises were the home of John Lloyd and Company, trimmers. The company seems to have finally sold all of its stock in February 1880. There are so many newspaper mentions of Lloyd’s business that I may have missed something referring to some other business operating from that address, hence the request for more information.
