Col. John O’Fallon
Like the city, O’Fallon Township was named after Colonel John O’Fallon who settled in the St Louis area after the War of 1812. He eventually rose to the position of president of the Ohio & Mississippi Railroad. Being this powerful enabled John O’Fallon to run the railroad east through Lebanon and Caseyville. In 1854, O’Fallon Station (the beginnings of present-day O’Fallon) began to form. In 1883, O’Fallon Township was established by a vote of 2,863 to 2,411. Over the years, St Clair County has been divided into 22 separate townships including our neighbors of Mascoutah, Lebanon, Shiloh Valley, Belleville and Caseyville.
