History

McHenry County was formed in 1836 out of Cook and LaSalle counties. The county was named for Major William McHenry, a member of the Illinois Militia during Tecumseh’s War, a major during the Blackhawk War in 1832, and a member of the Illinois House of Representatives and Senate. He died in Vandalia in 1835.

McHenry County originally stretched all the way east to Lake Michigan, with the county seat centrally in McHenry, but in 1839, the eastern townships of the county were carved out to form Lake County.
