One branch of my family contains a lot of people who worked for the Chivers jam trade in Cambridgeshire, England, either as factory workers, or as farmers/market gardeners. I thought I might create a freespace page for Chivers jam and its workers, to help me see connections. But I didn't see a pre-existing category that seemed a perfect fit. I suppose I could add 'Jam makers' under 'Food processing and transport occupations', but I was really hoping to focus on this particular business, and the other categories seem to contain only individuals. What would the categorization project recommend?
