History
The city was named after James Jennings, a farmer and merchant who moved to the area from Virginia with his family and retinue of slaves in 1839.<!-- citation covers paragraph as of 18 Feb 2023 --> In 1855, a railway was constructed which bisected the original Jennings property. Apparently the first commercial concern originating in the area was the Seed Dry Plate Company in 1883, which left for Rochester, New York around 1911 after its purchase by Eastman Kodak. The city benefited from the economic boom following World War II and was incorporated (with state and county administrations) in 1946.
