[2] In the Nebraska license plate system, Nuckolls County is represented by the prefix 42 (it had the 42nd-largest number of vehicles registered in the county when the license plate system was established in 1922).

[5] Nuckolls was also a notorious slaveowner who was followed by national news in 1860 when he tracked down an enslaved person he owned, named Eliza Grayson.

With the help of a professional kidnapper they attempted to remove the woman from Chicago, where she was found, only to be arrested by local law enforcement.

Nuckolls and the enslaved woman were put in the Chicago jail, only for an abolitionist mob to free her and shuttle her away to Canada.

Nuckolls went on to prominence and admiration in Nebraska after sympathizing with the Confederate states during the civil war.

[6] In 1887, Atchison, Topeka and Santa Fe Railway built a branch line from Neva, Kansas (3 miles west of Strong City) to Superior, Nebraska.

The Nuckolls County terrain consists of vegetation-covered rolling hills, sloped to the east.

In only one national election since 1936 has the county selected the Democratic Party candidate.
