Welcome to the Butler County Chapter of the Ohio Genealogical Society.

General Richard Butler

Butler County formed on March 24, 1803, from Hamilton County. The county is named for General Richard Butler. Richard Butler was born in Ireland in 1743 and came to the United States by 1760. As one of the traders that operated in Fort Pitt, he covered Pennsylvania and Ohio. General Butler served as a soldier in the American Revolution and died November 4, 1791, in a battle known as St. Clair’s Defeat.

Butler County is home to Miami University. Founded in 1809, Miami University is the 10th oldest University in the United States. Butler County has many historic homes including the 1799 birthplace of Ohio’s 19th governor William Bebb. Elisha Morgan’s Mansion was first constructed in 1817 in Fairfield. John Augsupurger established his farm in 1846 near Trenton. Benninghofen’s house was built in 1892 in Hamilton. In addition, there are currently 85 other locations in the National Register of Historic Places that call Butler County home.

There are 13 townships, 6 complete cities (and part of Sharonville which is also in Hamilton County), and 5 villages in Butler County. In addition, there are 8 areas which are “Census Designated Areas”.
