Search the historical London street directory, and London pub history site including early street addresses in London through the Victorian pub history of London. This search engine is not brilliant, try address searches in the main google search to get better results. Searches on people names do appear to work, I think. Let me know!
This excludes the Publicans listed at named Pubs in the Directory. The Directory does not include Public House names, just an address. This is fine for double checking names and places; but lacks the modern naming convention of a Public House and its named sign.
Many of these Beer Retailers (usually better known as Publicans) are very important in the fact that many formed the modern Public House as we now know it; whilst others were the modern equivalent of the Off Licence.
I will add links from these pages as I am able; but please help me out here. It is often difficult through the documentation that exists to match an address to a Pub name as much of this is through word of mouth, i.e. a Public House is often known by it's name to the locals, rather than through any record system.
