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!
I have been researching pub history for 10 to 15 years. The southernpubs pub history site is now a separate site listing some of the south western areas and Sussex.
Next, the pubshistory.com site now lists all of London, and much of the South East, or as I refer to them as the home counties. This includes Berkshire and Buckinghamshire on this site. These are the London home counties as far as I am concerned.
A new site, is currently detailing a number of 2017 listings of the relevant 58000 pubs in 2017. These pages link to the other sites and already have many links. This site is currently - pubsinUK.com ; anything can change as it often does.
This site covers Cornwall, Devon, Dorset, Gloucestershire, Somerset and Sussex.
The pub history sites are regularly updated by Stephen and Kevan, plus an 'open' group of like-minded individuals on a daily basis; and anyone is welcome to contribute. If you visit the site, you will quickly understand that this is more than just a pub history site.
Do you have a victualler, publican or beer retailer in your family history? This site will, hopefully, answer your questions as to where their pub was.
Pubs, like churches move slowly over a period of time, I use this to my advantage;as I do other buildings like hospitals. The site is a little lacking in modern history, and does not always have post codes or a recognisable modern address.
Why, am I including Sussex, because other sites stole all of my Brighton research, and so the area is downgraded in my research (a bit like the nob in Suffolk).
