Many accurate 1921 census transcriptions have already been added to the pub history site, including London, and parts of Middlesex. If you can contribute to the site, send me some details to Kevan, along with some description of the specific property.
The South side of Rochester Row would match with New Rochester Row in 1851, when no licensed premises or beer retailers are listed. In 1856, there were two beer retailers at 45 Rochester Row - the Lord Clyde and also at 28, or 29 Rochester Row, on the north side. That at number 45 is on the south side.
