The county-history sources names this settlement in its chapter on Bethlehem 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 10 fires within 5 miles of Rockville between 2005 and 2020, burning about 11 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:

• Navarre
• Bixler (historical)
• Knights Crossing
• Richville
• Smoketown
• Tarrymore

Every fire recorded in Stark County

Regional context, not property-specific evidence. Museums hold 139 specimens collected within 10 miles of Rockville between 1875 and 1975: 123 Animalia, 11 Plantae, 2 Fungi, 1 Unrecorded, 1 Protozoa, 1 Chromista. 12 distinct Species records are shown. Collected by A.M. Rogers, Armbruster, D. C. (Daniel C.), Borror, D.J. 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: Sand and Gravel, Construction, Clay, 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.
