London Robsons Street Directory in 1832 - King William street, Mansion house
Robsons 1832 directory index
This is the earliest street directory I have found so far which also includes pub history detail.
King William street, Mansion house is not listed in the Robsons 1832 street
directory
And in comparison from 1842, although with no links as it is an
image. It does include much more detail about trade details rather than
in 1832.
