The county history of 1912 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

Museums hold 94 specimens collected within 10 miles of Dekalb between 1842 and 1973: 62 Animalia, 28 Plantae, 4 Fungi. 12 distinct Species records are shown. Collected by Beal, L. E., Benjamin, J. R., Chase, H. (Hazel) and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.
