History[]

McHenry County was formed in 1836 out of Cook and LaSalle Counties. The County was named for Major William McHenry, an Indian fighter who 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.

President Gerald Ford's mother Dorothy Ayer Gardner Ford and maternal grandfather Levi Addison Gardner and possibly his maternal grandmother Adele Augusta Ayer Gardner were born in the county (near Harvard, Illinois).
