History of Clinton County

Clinton County was formed on December 21, 1837. It was named for DeWitt Clinton, a Governor of New York and most ardent advocate for the construction of the Erie Canal. The cities of DeWitt and Clinton were also named after him. In 1835, Elijah Buell built a log cabin for himself and his family and was thus the first settler of the region. In 1854, the first newspaper was issued. In 1858, the Lyons Female College for girls opened its doors; the tuition was set at US$175 per student. The county has used three courthouses in its history. The structure currently in use was constructed in Romanesque style and opened in 1897.
