According to Lippincott’s Gazetteer of the World: A Complete Pronouncing Gazetteer or Geographical Dictionary of the World, Somerset is defined as a post village located in Reading Twp., Perry County, Ohio on the Straitsville division of the Baltimore and Ohio Railroad, 24 miles S. by E. of Newark, and about 20 miles S.W. of Zanesville. It has a bank, four churches, a newspaper office, a carriage factory, and a woolen mill. Coal is found near this place. Population in 1900 is 1127.
The term, “post village,” a term not so common today was once very important to the establishment of rural communities. Once established as a postal village, the hamlet receives official recognition simply because a post office exists within the village.
One of the earliest known Postmasters of Somerset was Roswell Mills, who hailed from Connecticut. Mr. Mills was Postmaster in 1816.
