Please note Caldwell Street was called Holland Street in 1881 – see here.
Kelly’s Directory 1881 tells us that at 30 Holland street lived George Richard Worcester, a collar dresser (this was someone that attached collars to shirts)
Expanding on the info taken from Kelly’s Directory and looking at the Census we find out a little more…
Well actually we don’t. The census records I have for this part of the street in 1881 are badly damaged and so I am unable to delve any further with Mr Worcester. I have looked at the 1871 and 1891 Census, both of which show a different set of people living at number 30. Mr Worcester will remain a mystery.
