The community was founded in 1881 when the Wabash Railroad constructed a line through the area. It was originally named Butler after Butler Holloway, who was a real estate agent who first sold the lots of land. When a post office was established on July 19, 1881, there was already a Butler post office in the state, so the name Holloway was used instead. The post office operated until May 25, 1962.
• Raisin is a former settlement that contained its own post office from September 9, 1835, until March 22, 1855. Like the township and many other locations, it was named after the French word for grape, which were abundant in the area along the River Raisin.

When immigrants moved to the area in 1831, it became a prominent Quaker region. A post office opened here on June 9, 1868, and operated until November 29, 1902. The community once contained a station named Chase's when the Lake Shore and Michigan Southern Railroad built a line through the area in 1878.
