That uncertainty is not a gap in the record so much as it is the record. The site exists, officially, as a question mark pressed into the earth.

The story begins with a single observation made by Redington in 1911 or 1912, who recorded what he described as the foundations of a larger enclosure lying to the east of the doorway of the church at Kilcornan. An ecclesiastical enclosure, in early Irish Christian contexts, typically refers to a roughly circular or oval boundary, often a bank and ditch, that defined the sacred precinct around a church and its associated buildings. They are a familiar feature of early medieval religious sites across Ireland, though they vary considerably in scale and preservation. Redington offered no further detail beyond that brief note, and when the site was subsequently inspected, no visible surface trace could be found at all. The woodland has either swallowed what was there or, possibly, there was never quite enough to see in the first place.
