This topic has piqued my interest having just discovered a Tin Plate worker in my tree (who was also a journeyman). However, my ancestor appears to have a serious personality crisis because he also lists himself, at various times, as a Brazier, Ironmonger, Tin Plate Worker and Tin Man. Can all these occupations be interchangeable? He clearly served as an apprentice given that he calls himself a Journeyman in the 1851 census. Oh, and he's also very obviously a rural worker as he comes and lives in Ely. Perhaps he was a 'jack of all trades' for metal work in the city?
