Fulton County, Ohio: History
The first seat of justice in Fulton County was Ottokee, located there because of its central location in the county. A wooden courthouse was built in 1851.
However, a railroad was built further south. Wauseon sprung up in 1854 when the railroad was extended to that point, and incorporated in 1859. With the commercial success that the railroad brought to Wauseon, the citizens of the county voted to move the county seat to Wauseon in 1871. The Fulton County Courthouse was built in 1872.
