My Aunty Flo told me her mother my grandmother worked for a jam factory in nottingham she said it was Thackerays it was rather a disgusting story that my grandmothers sister Liz was being greedy and opened a jar of jam to eat it and found a hair ball in it. I too have tried to find a factory called Thackerays but couldnt find anything. I have only every found my grandmother working in the lace industry until 1905 when she married and moved to Shirebrook. Thank yo for all your posts.
