Search the London street directory and pub history site by surname, address or pub name
This could be useful in tracking the Publicans in the 1871 census.
Remember, Trade Directories are often out of date, so the information for 1869 may refer to 1867, for example.
My early ancestors were in Suffolk around this time, but I can find no Public Houses for Kettlebaston - perhaps they drank in the Beer Houses, or travelled some distance [a few miles] to visit the Pub, or brewed their own beer.
Plus a few Town & Village Directories
I thank the site Historical Directories for this information
