Rotherhithe index
The address is 309 Rotherhithe Street in 1871 and earlier, prior to street renumbering. The only place a name appears is in a 1789 Sun Fire Office insurance record at this address, but there's no indication in any of the Post Office directories until 1869 that this address was a beer retailer or a pub, so it may have had a different name by this point. *
