Hi Davie, thanks for your reply re sugar factories in Greenock. William and family definitely worked in one or the other. I was lucky enough to get the census info from another Rootschatter, which is great. They eventually left Greenock and moved to West Ham in London, where they worked at another sugar factory. It must have been big business in it's day and it would seem every dock had sugar processing going on. Cheers for your help.
