History of Morgan County, Ohio, with Portraits and Biographical Sketches of Some of Its Pioneers and Prominent Men, published 1886 names this settlement in its chapter on Meigsville Township. These are the passages that mention it, exactly as the scans read.

Regional context, not property-specific evidence. The federal wildfire occurrence database lists 13 fires within 5 miles of Unionville between 2012 and 2018, burning about 32 acres in total. None started naturally. None was 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:

• Hooksburg
• Hackney
• Neelysville
• Stockport
• Lovell
• Mill Grove

Every fire recorded in Morgan County

Regional context, not property-specific evidence. Museums hold 574 specimens collected within 10 miles of Unionville between 1887 and 1974: 477 Animalia, 87 Plantae, 9 Fungi, 1 Unrecorded. 12 distinct Species records are shown. Collected by A. D. Huryn, Adler, K. K., Albaugh, D. W. (Douglas W.) 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.
