On February 20, 1838, the Forrers established the first post office in Shenandoah under the name Shenandoah Iron Works with Henry Forrer being the postmaster. Development of the town ensued thereafter with houses, businesses, and industries developed astride of the Shenandoah River. The Shenandoah Iron Works, which was owned and operated by Daniel and Henry Forrer, was also located along the river banks. Ten houses were built facing the river in the Furnace Hollow section of town by a man named Mr. Pee Dee, hence, the name of this section of town today. Other historical structures were also built including Stephens Cottage, the South Fork House, Mt. Lebanon United Church at Comertown, and the Old Verbena Mill in Verbena, just south of town off Route 340.
