Trade City:
Trade City was formerly known as Davidsville, named after David Mutersbaugh who laid out the town in the fall of 1852. After he did that, he moved to Virginia. Peter Dilts built the Davidsville Hotel that same year, as a dwelling, a storehouse, and a store. The hotel opened for business in 1853. The second building, a dwelling and a wagon shop, was out up by Frederick Sprankle who went on the start the village of Sprankle Mills. This building was later a carriage and wagon factory.
The history book I got this information out of does not record when the name Trade City was adopted, or why. One story I heard was that this intersection was a good central location for farmers of the area to trade their goods, hence the name. Presently, Trade City is nothing more than a rural intersection, looking nothing like a city... or harboring much trade for that matter!
