History of Gallia County
Gallia County was formed on March 25, 1803, from portions of Adams and Washington counties. Gallia County had originally been settled by French immigrants, who named the county “Gallia”, the Latin name for Gaul, the ancient region of Western Europe which included present day France.
In the 19th century, the county was settled by numerous migrants from the Upper South, who traveled to the territory by the Ohio River. In the antebellum years, some of its towns became centers of settlement by African Americans, both free blacks (some also from the South) and refugee slaves who had escaped their owners and come across the river to a free state. There were some whites and Native Americans in the Blackfork settlement as well.
In 1818, a group from Wales settled in Gallia County, with Welsh remaining Gallia County’s most common second language until 1970.
