The county history of 1883 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

Museums hold 321 specimens collected within 10 miles of Markley (historical) between 1889 and 1973: 308 Animalia, 9 Fungi, 4 Plantae. 12 distinct Species records are shown. Collected by B. Fink, B. Montgomery, L. Alward & P. Alward, Beattie R. K. 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.
