History of Fairfield County, Ohio, and Representative Citizens, published 1912 names this settlement in its chapter on Bloom 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 1 fire within 5 miles of Jefferson between 2012 and 2012, burning about 25 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:

• Canal Winchester
• Carroll
• Chester Heights
• Greencastle
• Harley
• Havensport

Every fire recorded in Fairfield County

Regional context, not property-specific evidence. Museums hold 1,818 specimens collected within 10 miles of Jefferson between 1859 and 1975: 1,723 Animalia, 60 Fungi, 34 Plantae, 1 Protozoa. 12 distinct Species records are shown. Collected by Bales, B. R., Birch, W., Bitterly, K. (Kermit) 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 1 working within 5 miles of Jefferson: 1 producer. All of them still produce. What was taken out: Sand and Gravel, Construction. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.
