The county history of 1881 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

Museums hold 256 specimens collected within 10 miles of Park Layne Manor between 1870 and 1975: 188 Animalia, 35 Fungi, 25 Plantae, 7 Protozoa, 1 Unrecorded. 12 distinct Species records are shown. Collected by A JOHN, A. N. Leeds, A. R. Gaufin 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.
