Were Confectioners formerly what we think of today, sweet makers? Or did they, in the past, besides cakes, pies,and sweet treats, make and sell savoury treats as well? There is a book printed in 1800 "The Complete Confectioner" and the table of contents alone is 34 pages long and includes items that we can only wonder at what they may be. Flummery sounds rather nice though.
If your ancestor was a confectioner add them to this project.
