In 1882, an organization by the name of "John Otis & Company" built a large charcoal furnace just south of Mancelona. The company also platted a town around the furnace, naming it "Furnaceville". Soon after, the Grand Rapids and Indiana Railroad built a station here. The furnace flourished, and in 1886 a group of businessmen from Grand Rapids bought out the company, and renamed the company Antrim Iron Works and the town Antrim. Today, Antrim is still a small subdivision on the south side of Mancelona, and one of the street names is Otis.
