The county history of 1882 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

Museums hold 463 specimens collected within 10 miles of Airhill between 1877 and 1974: 443 Animalia, 9 Plantae, 7 Fungi, 3 Protozoa, 1 Unrecorded. 12 distinct Species records are shown. Collected by Allen, John, Arden R. Gaufin, BOYER AND DUELLMAN 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.
