County of jersey

History & Founding

Located in southwestern Illinois, this county holds a rich history and a distinctive character shaped by its geography and the people who have called it home. Established in 1821 from a portion of Greene County, its name derives from the island of Jersey, one of the Channel Islands, a nod to a group of settlers from New Jersey who initially settled in the area. Early inhabitants included Native American tribes, primarily the Sauk and Fox, before European settlement. The county played a role in the Underground Railroad, with several homes and barns serving as safe houses for escaping slaves traveling north towards freedom. A fascinating anecdote tells of a local farmer, William Henry, who, during the Civil War, cleverly concealed runaway slaves in a specially constructed underground room beneath his barn, successfully evading detection by Confederate sympathizers. This county's development mirrored Illinois’s broader growth, transitioning from an agricultural frontier to a more diversified economy.

Geography & Landscape

The county’s geography is defined by the rolling hills and fertile river valleys of the Illinois Uplands. It sits along the Mississippi River, its western border a significant natural feature. The county encompasses approximately 369 square miles, a mix of farmland, woodlands, and small towns. Several creeks and streams, including the Fox Creek and the Indian Creek, contribute to the area's beauty and provide valuable resources. The climate is typically humid continental, characterized by warm, humid summers and cold winters. While not mountainous, the gently undulating terrain provides scenic vistas, particularly during the autumn foliage season. The land's rich soil has historically made it ideal for agriculture, and the river access facilitated early transportation and trade.

Economy & Communities

The county is comprised of four incorporated towns: Jerseyville, Grafton, Elsah, and Brighton. Jerseyville, as the county seat, is the largest population center. The local economy historically relied heavily on agriculture, particularly corn and soybean production. While agriculture remains important, the economy has diversified over time. Tourism plays a growing role, especially in Grafton, which attracts visitors with its scenic riverfront and proximity to the sprawling Pere Marquette State Park. Manufacturing, particularly in the automotive supply chain, also contributes to the local economy. Notable employers include companies involved in agriculture, manufacturing, and tourism. The overall character of the area is predominantly rural, with a strong sense of community and a slower pace of life, though Grafton’s tourism industry brings a vibrant energy to that specific location.
