HistoryA character grade: shown, never part of Addison Township’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 Addison Township’s 0.2 sits near the middle of its state (58% of Illinois towns have fewer) while its 2 historic buildings outnumber those of 60% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from C+ to B+. The pre-1940 share (±1.0 points) is firm at this size. Two sources give 1839.

Timeline
Addison Township, 1839 to 1900
Woven from the archive, old maps, post office records, the National Register and the people born here.
The village was incorporated in 1884, at which time it had a population of 400. The community itself was originally named Dunkley's Grove after the settler Hezekiah Dunklee, and was renamed after a town in England or Addison, New York. In 1832, Winfield Scott built Army Trail Road on top of a Potawatomi trail in Addison, in order to allow 50 broad-tired wagons to fight Black Hawk and his warriors. In 1864, the Lutheran Church–Missouri Synod moved its teacher training to the village from Fort Wayne, Indiana, and established the Addison Teachers Seminary; it remained in Addison until 1913, when it was relocated to River Forest, Illinois, as Concordia Teachers College (now Concordia University Chicago). The town was also home to the Kinderheim home for children, which made up more than half its population prior to suburbanization.
