History of Clermont County
Clermont’s name is borrowed from a prefecture in France notable as the home of Celtic leader Vercingetorix who led the unified Gallic resistance to Roman invasion. Clermont connotes “clear mountain,” which describes the hills when viewed through the thick Ohio River fog. During the Age of Discovery, the French became the first recorded Europeans to see this land from the Ohio River, though Clermont’s population dates to the Paleoindian, Adena, Hopewell, and Fort Ancient cultures. The Gatch Site and other sites provide glimpses into what life was like for these people. The Shawnee, Miami, Lenape, Mingo, Odawa, Cherokee, and Wyandot each have or had a presence in Clermont.
At its ordinance in 1800 by the Commonwealth of Virginia to reward Virginian military veterans with land bounties, Clermont encompassed twenty three current Ohio counties and over 4.2 million acres of dense old growth forest. The first deed was issued on February 20, 1796. George Washington owned three parcels of land in Clermont County, whose first capital was Williamsburg, founded by William Lytle, and like Milford, was founded in 1796. A stone dairy house, constructed in 1800, is thought to be the oldest standing building in Clermont. The edifice is located beside Harmony Hill on South Third Street in Williamsburg. Harmony Hill, one of the area’s first farms, was built by William Lytle. The last American Indian village was located two miles south of Marathon in Jackson Township, along the mouth of Grassy Run on the East Fork of the Little Miami River. The site saw the largest frontier battle in Clermont, the Battle of Grassy Run, during which pioneer Simon Kenton clashed with chief Tecumseh on April 10, 1792. The Wyandot lived at this site until 1811. The Bullskin Trail, once a major American Indian trail, runs north and south through Clermont along Ohio Route 133, and was used by frontiersmen Kenton and Daniel Boone on hunting and warfare expeditions. In 1823, New Richmond became the seat, and in 1824, the seat moved to Batavia, the county’s current seat. Clermont’s Moscow became the exiled home of French royalty during the early 1800s, including future King of France Louis Philippe in 1815 and the Marquis de Lafayette in 1825. Point Pleasant was birthplace and boyhood home of military hero, Union general, and President Ulysses S. Grant, born on April 27, 1822; although Grant spent little time in Clermont, and both his political and military careers were disconnected from it.
