Ogle County was formed in 1836 out of Jo Daviess and LaSalle counties, and named in honor of Captain Joseph Ogle, a veteran of the Revolutionary War who settled in Illinois in 1785. Ogle County government was organized in 1837; before that time it remained assigned to Jo Daviess County for purposes of legislative, taxation, and judicial matters.  In 1839, a portion of Ogle County was partitioned off to form Lee County.
Ogle County was a New England settlement. The founders of Oregon and Rochelle arrived from New England; they were " Yankees", descendants of English Puritans who had settled New England in the 1600s. They were part of a wave of farmers who migrated into the Northwest Territory in the early 1800s, their trek eased by completion of the Erie Canal in 1825. They found virgin forest and wild prairie, and quickly laid out farms, constructed roads, erected government buildings and established post routes. They brought a passion for education and strong abolitionism. They were members of the Congregationalist or Episcopalian Church. Culturally Ogle County, like much of northern Illinois would maintain values similar to those of New England.
