A small coal mining town, most of the homes in Marlin, PA, were built between 1900 and 1920s. Its residents were employed by a coal mining company. Because many of its residents are transient, living in the area for weeks or months at a time, several homes in the town are owned by the company. The streets are aptly named after ores and precious gems that can be found in the local mines: ruby, silver, coal, emerald, and others. It’s unclear how exactly the town of Marlin came by its name, but local lore says it’s an amalgamation of two now-defunct coal mine companies’ names.
