Hi DIAshurst
I see your temptation but in my census occupations search I did not find anywhere a word monger. I found several other types of mongers, and in Cumberland, there are
wood mongers in different Cumberland census ie
Casson, Drummond, Harrison, Hudson, Jameson Kirkby, Nicholson, Ostle Robinson Warwick, Wood
In nearby Dumfriesshire there are two families of Bryden who had iron mongers in the family but none found in Cumberland
that funny description iron ore miner and newsagent lead me to Thomas Dixon Whitehaven which led me to William Dixon b Caton Lancashire but now 1881 in Market st Bootle staying with his brother Jabez Dixon b 1843a General Ironmonger Master who has wife Mary b 1847 Caton Lancashire Any connection?
happy to look more but need some more info
