HistoryA character grade: shown, never part of South Holland’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 South Holland’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 (±1.5 points) is firm at this size. Two sources give 1847.

Timeline
South Holland, 1847 to 1977
Woven from the archive, old maps, post office records, the National Register and the people born here.
The area currently occupied by South Holland, Illinois, was first settled in 1846 by immigrants from South Holland, Netherlands. When the community formally incorporated as a village in 1894, its population was about 1,000. Originally a general farming community, it later specialized in vegetable growing, especially onion sets. By the 1940s South Holland was known as the "Onion Set Capital of the World". The town was built on low ground near the Calumet River and was originally called de Laage Prairie (Low Prairie) to differentiate it from another Dutch settlement further north on higher ground and called de Hooge Prairie (now the Roseland neighborhood of Chicago).
In 1847, according to Wikidata. South Holland’s post office opened in 1870, and the census of 1890 counted 1,005 people here.
