The story

How Duncan came to be

From Wikipedia’s history of Duncan.

Read it all →

The transcontinental railroad reached the site of Duncan in 1866. Among the first settlers in the area were Polish and Swiss immigrants.

In June 1869, the post office of Cherry Hill was established on the site.

In October 1871, the townsite of Jackson was laid out by officials of the Union Pacific Railroad. Jackson was chosen in 1879 as the southern terminus of the Omaha, Niobrara, and Black Hills Railroad, a Union Pacific subsidiary, purportedly because railroad magnate Jay Gould was angry at the town of Columbus for promoting a rival railroad in the region.

The new name honored General Wood B. Duncan, a prominent onetime local resident.
