There was no “farm country” back in the day.

which is why my hunch is this structure dates from the late 1700’s (post Rev) or very early 1800’s, when settlers were moving into Ohio and were still vulnerable to attacks into the 1790’s (or later into the 1800’s? Ohio historians?)

someone was settled on this land enough to build a stone structure -

just wonder if they have investigated whether the stone is encasing or replaced an older log structure, as has been suggested occurred with some of the original log blockhouses in pre-Rev war PA that are contained within later built homes

That is where they found my ancestor Lochry’s 1774 blockhouse- within a farmhouse built over it

The earlier farming was by Indians. There's an area there to the West with dozens of Indian villages. They'd been surrounded by miles of corn. Earlier Europeans (my take is they were Spanish) introduced wheat, barley and rye so you'd have the same Indians growing that to trade with passing Europeans.

Widespread European farming didn't get going until just some time after the French and Indian War ~ in this area.
