HistoryA character grade: shown, never part of Hinckley’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 Hinckley’s 0.0 sits below most of its state (28% of Illinois towns have fewer) while its 0 listings outnumber those of 23% 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 is a Census survey estimate (±8.7 points). The founding year is the first post office, not a stated founding date.

What stands out about Hinckley’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In the 1830s, a Mr. Hollenbeck, who lived near Ottawa, Illinois, was traveling the then-unsettled territory. He found a grove of trees west of the present-day Hinckley and named it Squaw Grove, after the Native American women who were tending camp.
In the spring of 1835, John Sebree built a log house. The following year, more families came to the area and a small town was started at the west edge of what is now Hinckley, which was named Squaw Grove.
Hinckley was conceived in the 1870s as the brainchild of Francis Hinckley, president of the Chicago and Iowa Railroad. The rail line was placed one-half mile east of the Village of Squaw Grove, which was then named Hinckley.
