Measuring roughly fifteen metres east to west and ten metres north to south, it is easy to overlook entirely, yet the name attached to it carries considerable weight. The word "killins" derives from the Irish "cillín", referring to an unconsecrated burial ground used for those excluded from formal Christian burial, most often unbaptised infants. These sites are scattered across Ireland, typically located at the margins of settled land, and they represent one of the more quietly sorrowful features of the rural Irish countryside.

The enclosure appears on the 1835 edition of the Ordnance Survey six-inch map, marked in bold italic lettering as "Killins", a cartographic convention that typically signals a feature of local significance. Alongside the mapped enclosure, local tradition holds that a children's burial ground once occupied the interior of a nearby cashel, a cashel being a stone-ringed enclosure of early medieval origin, usually associated with a farmstead or ecclesiastical settlement. The connection between the cillín and the cashel suggests a landscape with layered use over many centuries, each generation quietly placing its losses within boundaries already considered old. No physical trace of the burial ground is visible today, though local knowledge places it within the southern part of the cashel's perimeter.
