An account from the chapter on Muskingum township, in the words of 1902.

The county history of 1902 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 3 fires within 5 miles of Unionville between 2015 and 2016, burning about 6 acres in total. 1 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:

• Rainbow
• Stanleyville
• Whipple
• Alden
• Bonn
• Buells (historical)

Every fire recorded in Washington County

Museums hold 1,287 specimens collected within 10 miles of Unionville between 1853 and 1975: 1,200 Animalia, 54 Fungi, 31 Plantae, 1 Unrecorded, 1 Chromista. 12 distinct Species records are shown. Collected by A. D. Selby, A. Drew, A. L. McElhose 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.

Every working recorded in Washington County

The eight closest, with where each one stands in the county. Distances are straight-line, computed from the Geographic Names Information System coordinates.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 1077104. The sheet list is computed by point-in-boundary test against the United States Geological Survey's historical topographic inventory.
