Rosebush began in 1844 when Cornelius Bogan started a general store. He called the town Halfway because it was approximately halfway between Clare and Mount Pleasant. In 1868, the Ann Arbor Railroad came through the area and resident James Bush, while officially platting the land, bartered with the railroad some of his property for the right to have the station named after his wife, Rose. An addition to the community was later platted in 1873 by Elias B. Calkins and named Calkinsville – this was the name of the original post office on July 9, 1873. The post office name was changed to Rosebush in 1889, back to Calkinsville in 1890 and once again Rosebush on February 19, 1903. The name has remained unchanged since.
