History of Norfolk County, Massachusetts, with Biographical Sketches of Many of Its Pioneers and Prominent Men, published 1884 names this settlement in its chapter on Dedham Town. These are the passages that mention it, exactly as the scans read.

Regional context, not property-specific evidence. The federal wildfire occurrence database lists 151 fires within 5 miles of Dedham Island between 2003 and 2020, burning about 412 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:

• East Dedham
• Riverdale
• Ashcroft
• Birds Hill
• Dedham
• Ellis

Every fire recorded in Norfolk County

Regional context, not property-specific evidence. Museums hold 15,325 specimens collected within 10 miles of Dedham Island between 1810 and 1975: 5,877 Plantae, 4,775 Fungi, 4,092 Animalia, 289 Protozoa, 191 Chromista, 65 Unrecorded, 36 Bacteria. 12 distinct Species records are shown. Collected by (MARSDEN, H W), ?, ? ex Herb. W.G. Farlow 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.

Regional context, not property-specific evidence. The federal mineral resources record lists 4 workings within 5 miles of Dedham Island: 3 past producers, 1 unknown. None of them still produces. What was taken out: Sand and Gravel, Construction, Stone, 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.
