History

Kendall County was formed in 1841 out of LaSalle and Kane counties.

The county is named after Amos Kendall. Kendall was the editor of the Frankfort, Kentucky newspaper, and went on to be an important advisor to President Andrew Jackson. Kendall became the U.S. Postmaster General in 1835.

Geography

According to the U.S. Census Bureau, the county has a total area of 322 square miles (830 km2), of which 320 square miles (830 km2) is land and 2.0 square miles (5.2 km2) (0.6%) is water.

Kendall County is a small, but rapidly growing county that has the majority of its population in the northeast, and along the Fox River (the only river in the county) which runs through the northwestern section of the county. Many new subdivisions have been constructed in this county, which has produced considerable population growth. Southern Kendall still remains largely agricultural. Kendall County has two primary ranges of low-lying hills formed by what is known as an end moraine. Ransom, the more predominant of the two moraines, runs through the west and north-central part of the county. This moraine has created elevations of over 800 feet (240 m), in contrast to elevations in southern Kendall County that drop to the lower 500 feet (150 m) range. Minooka, the other major end moraine ridge in Kendall County, runs along its entire eastern border with Will County. The two moraines intersect at almost a right angle in the township of Oswego. The only designated state park in the county is Silver Springs State Fish and Wildlife Area.

Townships

The county is an 18-mile (29 km) square which is divided up into 9 townships. Each township is divided into 36 1 mile square sections, except that the Fox River is used as a Township border, resulting in Bristol being the smallest township with the extra area being assigned to Oswego and Kendall Townships. There are also two exceptions to the section grid to reflect Indian land grants under the Treaty of Prairie du Chien[disambiguation needed] in 1829: the Mo-Ah-Way Reservation in Oswego Township and the Waish-Kee-shaw Reservation in Na-Au-Say Township. These areas were eventually sold to European settlers.
