SENECA COUNTY- Seneca County officially began on April 1, 1824. Its story starts earlier, with forts built during the War of 1812. This short history draws on Seneca County in 1824, a history published by Destination Seneca County, and the county’s Ohio historical markers.

Forts on the army road

During the War of 1812, Gen. William Henry Harrison’s army cleared a road north through the area in 1813, known as Harrison’s Trail or the Old Army Road. Fort Ball was built along the Sandusky River in the summer of 1813 and named for Col. James Ball. Fort Seneca, to the north, served as Harrison’s command post during the Battle of Fort Stephenson at what is now Fremont.

The 1824 history says President James Monroe passed through the area in August 1817.

Settlers and the Seneca

Erastus Bowe arrived in November 1817 and ran a tavern. The state’s Camp Ball marker says Bowe’s settlement marks the beginning of both Seneca County and Tiffin.

The 1824 history says most Native people living here at the time were Wyandots, Senecas and Delawares, and that an 1817 treaty set aside a 40,000-acre reservation for the Senecas, home to about 500 people in 1824. Most were removed from the area beginning in 1831.

The county is created

The Ohio General Assembly passed the act creating Seneca County on Jan. 22, 1824, effective April 1, 1824. The county started with four townships: Thompson, Seneca, Eden and Clinton. The first court case was heard on April 12, 1824. The county’s first jury trial, the “Brush Dam Case,” was filed in September 1824 and decided in April 1825.

Tiffin and Fort Ball

The village of Oakley was platted in 1819 and renamed Fort Ball in 1823. Across the river, Josiah Hedges acquired land in 1821 and named his village Tiffin, after his friend Edward Tiffin, Ohio’s first governor. The Founding of Tiffin marker tells that story. Tiffin became the county seat, the first bridge between the two towns was built in 1833, and Tiffin and Fort Ball merged in 1850.

Firsts and landmarks

• The 1824 history says the county’s first grist mill was built near Melmore in 1821.
• The Mad River and Lake Erie Railroad, described on its state marker as the first rail line built entirely in Ohio, reached Tiffin by 1841.
• Tiffin’s Edison electric company, organized in late 1883, was the first central power station in Ohio, according to the “Early Electric Illumination” marker.
• Sisters Nettie and Florence Cronise of Tiffin became the first women admitted to the Ohio bar. Nettie applied in April 1873, according to the state marker at the courthouse square.
