HistoryA character grade: shown, never part of Derby’s overall grade.
Kansas towns list more on the Register than most of the country (a typical Kansas town has 5.1 per 10,000 residents, the U.S. 2.4), so Derby’s 0.4 sits near the middle of its state (38% of Kansas towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D to C. The pre-1940 share (±0.5 points) is firm at this size. Two sources give 1871.

What stands out about Derby’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
In 1870, settlers John Haufbauer and J.H. Minich built the first houses, smithies, and general stores on the site that would become Derby. In 1871, the community was named El Paso, after El Paso, Illinois, and was laid out and platted. In 1880, the Atchison, Topeka and Santa Fe Railway changed the name of its rail station to Derby, after railroad official C.F. Derby, to avoid confusion with El Paso, Texas.
In 1903, the city incorporated with the name El Paso, but the city remained largely a rural community until after World War II.
In 1871, according to Wikidata. Derby’s post office opened in 1870, and the census of 1890 counted 236 people here.
