The county history of 1880 has no passage naming this settlement, which was common for the smaller places. Its township is covered in full.

The federal wildfire occurrence database lists 9 fires within 5 miles of Rokeby Lock between 2012 and 2014, burning about 24 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:

• Eagleport
• Durant
• Joetown
• Halls Valley (historical)
• Triadelphia
• Airington (historical)

Every fire recorded in Morgan County

Museums hold 284 specimens collected within 10 miles of Rokeby Lock between 1887 and 1974: 255 Animalia, 20 Plantae, 8 Fungi, 1 Unrecorded. 12 distinct Species records are shown. Collected by A. D. Huryn, Adler, K. K., Albaugh, D. W. (Douglas W.) 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.
