The county history of 1903 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

The federal wildfire occurrence database lists 58 fires within 5 miles of Twin Valley between 1997 and 2020, burning about 875 acres in total. None started naturally. 8 were recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.

Settlements close enough to share some of these fires:

• Rubyville
• Rushtown
• Sciotoville
• Coles Park
• Happy Hours Addition
• Highland Bend

Museums hold 1,021 specimens collected within 10 miles of Twin Valley between 1884 and 1975: 944 Animalia, 42 Plantae, 29 Fungi, 3 Protozoa, 2 Unrecorded, 1 Chromista. 12 distinct Species records are shown. Collected by ?, A.P. Morgan, A.P. Morgan; L.V. Morgan 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.
