The History of Union County, Ohio, Containing a History of the County; Its Townships, Towns ... Military Record;, published 1883 names this settlement in its chapter on Dover Township. These are the passages that mention it, exactly as the scans read.

Regional context, not property-specific evidence. Museums hold 530 specimens collected within 10 miles of New Dover between 1880 and 1975: 515 Animalia, 10 Fungi, 4 Plantae, 1 Unrecorded. 12 distinct Species records are shown. Collected by A. Spreitzer, A. Spreitzer & K. Borror, A. Spreitzer & W. LeGrande 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.

What was taken out: Stone, Crushed/Broken. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.
