Iron ore was discovered in eastern Armstrong County in the 1850's. The Phoenix Furnace existed somewhere near Milton and the McCrea Furnace was in what is now McCrea, which these days is nothing more than an intersection. There were other little towns like Eddyville that had a saw mill, a grist mill, a distillery, a store, a boatyard, a black smith shop and a dozen houses. McWilliams, once known as Charleston, was about the same. The industries were going well in 1873, but one hundred years later there is little there. There were towns of Presque Isle, Independence, and Mudlick that have no indications on any of our modern maps, having disappeared completely. Some like North Freedom are still the site of commerce. A sawmill was built in North Freedom in 1833, and the town was named by Jonathan Yount in 1871.
