HistoryA character grade: shown, never part of Carrier Mills’ 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 Carrier Mills’ 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 (±6.5 points). Two sources give 1872.

The first settler in the village now known as Carrier Mills was Hampton Pankey. He was also one of the earliest settlers in Saline County. Pankey was living in the area in 1804 or 1805 and he registered his land deed in 1814, the earliest date that was available to register them. In about 1811 the settlers began building blockhouses for protection from American Indians. A blockhouse was built on his land around this time. One of his sons was John Pankey, who was one of the founding fathers of Harrisburg.
