History of Worcester County, Massachusetts : with Biographical Sketches of Many of Its Pioneers and Prominent Men., published 1889 has no passage naming this settlement, which was common for smaller places. Its township is covered in full.

Regional context, not property-specific evidence. The federal wildfire occurrence database lists 127 fires within 5 miles of Rocky Hill between 2003 and 2020, burning about 216 acres in total. None started naturally. 37 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:

• Hopedale
• Milford
• North Milford
• Spindleville

Regional context, not property-specific evidence. Museums hold 346 specimens collected within 10 miles of Rocky Hill between 1844 and 1975: 141 Plantae, 119 Animalia, 83 Fungi, 3 Unrecorded. 12 distinct Species records are shown. Collected by A. B. Seymour, A. P. D. Piguet, A. R. Hodgdon; F. L. Steele 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.
