Gallatin is one of the five towns of the Roe Jan region and is an important hamlet in the History of the Roe Jan Region. Because of its location on the Roeliff Jansen Kill , Gallatinville was the largest settlement in the early Roe Jan towns, with a railroad station, a hotel, stores, a grist mill, a plaster mill, two blacksmith shops, a post office and about a dozen houses by the 19th century.
