Locally it is called the "keel field", and the word keel is thought to derive from "cillíneach", an Irish term for a children's burial ground. Nothing marks the surface of the ground. No mounds, no stones, no enclosures; just ordinary grassland on an ordinary slope.

Cillíní, as these sites are collectively known, were informal burial places used across Ireland for centuries, most commonly for unbaptised infants who, under Catholic teaching of the period, could not be interred in consecrated ground. They were often sited at liminal locations, old boundaries, the edges of townlands, or ground that already carried some sense of age or separateness. The practice was widespread but rarely documented, and the sites were typically unmarked by design, their locations passed on through local memory rather than any official record. In Brownstown, that memory survives only in the field name itself. There are no visible remains at ground level, meaning whatever physical traces may once have existed have been erased by centuries of agriculture, or were simply never made in the first place.

What survives here, then, is purely linguistic: a placeholder in the landscape, a name doing the work that a stone or an enclosure might otherwise do. The keel field is the kind of place that repays attention precisely because there is nothing obvious to see.
