Caldwell's Illustrated Historical Atlas of Adams County, Ohio. 1797-1880, published 1880 names this settlement in its chapter on Wayne 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 28 fires within 5 miles of Youngsville between 2004 and 2020, burning about 73 acres in total. None started naturally. 3 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:

• Irvington (historical)
• Mount Zion (historical)
• Harshasville
• Seaman
• Tranquility
• Buck Run (historical)

Regional context, not property-specific evidence. Museums hold 616 specimens collected within 10 miles of Youngsville between 1866 and 1975: 376 Animalia, 151 Fungi, 71 Plantae, 18 Protozoa. 12 distinct Species records are shown. Collected by A. B. Seymour, A. Cronquist, A. J. Sharp 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.
