I have a family of Calico Printers, Copperplate Printers and Block Printers all living in Merton Surrey between 1841 and 1881 (might be later but I haven't checked). One is a table cover printer. My family lived in Nelson's Fields, Double Row for many years and nearby was a daughter with son in law, and another brother in law. On scrolling through the 1851 census for example, there are lots of printers and copper workers so there must have been some local industry supporting them. One occupation for the girls seemed to be 'tierer' (from the french word tirer - to pull I think) and I seem to recall a conversation with @PeterG some years back in another place that this was something to do with cloth. Can anyone suggest how I might find out what industry was there at this time? It is absolutely fascinating and seemed to have supported my family for many years with there being very few deaths of children.
