TOWNS
In 1824, with the establishment of Seneca County [†] by the Ohio Legislature, Tiffin became a county seat. The county took its name from the Seneca Indians, who originally were native to this territory.
Oakley and Tiffin, split by the Sandusky River, were great rivals. But, in 1850, seeing that later their interests lay together, the two villages merged to form greater Tiffin, with Fort Ball becoming a part of Tiffin in March of that year.
Seneca County was known principally for its agricultural products, and consistently rated in the upper 12% of the 88 counties in Ohio in gross farm income until the year 1888 when oil was discovered in the area. Oil attracted industry and by 1900 numerous manufacturing concerns had moved to Tiffin and Seneca County. Industrial growth has continued to the present day, adding greatly to the economic progress of Seneca County.
