## History

[edit | edit source]

The land that became Stephenson County was first settled by William Waddams in 1832, who founded Waddams Grove.[3] By 1837, population was sufficient to form Stephenson County, taking land from Jo Daviess and Winnebago counties. The county was named for Colonel Benjamin Stephenson, an official of the Illinois Territory.[4]
