What drives Deerfield’s History grade
On its age, its old homes and the National Register, Deerfield is more historic than 32% of U.S. towns, #538 of 768 in Illinois. Its National Register listings hold the grade up; its share of homes from before 1940 pulls it down.
C
HistoryA character grade: shown, never part of Deerfield’s overall grade.
Few Illinois towns list much on the Register (a typical Illinois town has 0.5 per 10,000 residents, the U.S. 2.4), so Deerfield’s 0.5 sits near the middle of its state (60% of Illinois towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C− to C+. The pre-1940 share (±1.1 points) is firm at this size. The founding year is the first post office, not a stated founding date; Wikidata gives 1903.

What stands out about Deerfield’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Originally populated by the Bodéwadmiakiwen (Potawatomi), Myaamia (Miami), Kiikaapoi (Kickapoo), and Peoria Native Americans, the area was settled by Horace Lamb and Jacob B. Cadwell in 1835 and named Cadwell's Corner. A shopping center located on the site of Cadwell's farm at Waukegan Road and Lake Cook Road still bears that name. The area grew because of the navigable rivers in the area, notably the Des Plaines River and the Chicago River.

Highwood is a village in the township of Deerfield, on the railroad, adjoin¬ ing the town plat of Highland Park on the north, but the depot or station house at this place is about a mile from that at Highland Park. The town plat of this place was laid out in April, 1871. It is about three miles south of Lake Forest. It is connected with Highland Park by broad avenues, on some of which the buildings are scattered along, so that the dividing point between the two places is not discernible. The streets and avenues were first laid out by Rev. Dr. Evarts. Directly east of the railroad depot he secured a handsome
