Mr. Glover (made gloves)
Mr. Tinker (sold pots and pans and other household items)

Mr. Carter (sold use of his carts to carry things around)

Mr. Miller (milled grain into flour)
Mr. Sawyer (cut timber)
Mr. Brewer( brewed beer)
Mr. Fuller (worked with cloth)
Mr. Hooper (worked with barrels)
Mr. Porter (door keeper)
