What drives Washington’s History grade
On its age, its old homes and the National Register, Washington is more historic than 76% of U.S. towns, #217 of 768 in Illinois. All 3 inputs are above most U.S. towns; its age ranks highest and its share of homes from before 1940 lowest.
A−
HistoryA character grade: shown, never part of Washington’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 Washington’s 2.5 sits above most of its state (68% of Illinois towns have fewer) while its 4 historic buildings outnumber those of 68% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B+ to A−. The pre-1940 share (±2.9 points) is firm at this size. Two sources give 1825.

Washington was settled in 1825 by William Holland Sr., who came from North Carolina and was hired by the U.S. government to provide blacksmith services to the local Native Americans. During his long and eventful life, he was married three times, and was the father of twenty-one children: fourteen by his first wife and seven by his second wife. He had eighty-two grandchildren and fifty great-grandchildren. He died in Washington on November 27, 1871, at the age of ninety-one. The post office (and later the city) was originally named Holland's Grove on February 12, 1833 before being renamed in honor of the first U.S. president, George Washington, on September 13, 1837.
