History
Livingston County was founded on February 27, 1837. It was named after Edward Livingston, a prominent politician. He was the mayor of New York City, represented New York in the United States House of Representatives, then represented Louisiana in both houses of Congress. He was Andrew Jackson's Secretary of State, and the United States Minister to France. Although he had no connections to Illinois, the General Assembly found him accomplished enough to name a county after him.
