The original Goshen Mills consisted of a three-story brick merchant mill and a smaller frame grist mill, constructed after 1737 by Ignatius Pigman to serve a small farming community. The facility relied on water supplied by the Goshen branch, which flows into the Great Seneca Creek, and water-powered wheels turned four flour mill stones that converted local wheat and corn crops into finished products such as flour and meal for consumption. By 1800, when Edward Crow managed the property, there were 44 mills in Montgomery County, seven of them on Seneca Creek and its tributaries. To distinguish his mills from competing operations, Crow advertised that the facility had materials on hand to construct a saw mill and identified a rich copper mine on the surrounding acreage. Crow sold the mills in 1803 to Samuel Robertson, who resided at Fertile Meadows. Operations continued under the Riggs family until 1890, when fire destroyed the outdated milling complex.
