In a corner of a roadside field in County Kildare, on level pasture just to the north-west of Ardscull graveyard, lies a patch of ground that holds no headstones, no kerbing, and no visible sign that anyone is buried there at all. It is a cillín, or children's burial ground, one of many such sites scattered across Ireland where unbaptised infants were interred separately from the main consecrated graveyard. Because Catholic doctrine once held that the unbaptised could not enter heaven, these children were denied burial in holy ground, and their families found quiet, unmarked places at field edges, riverbanks, and old earthwork boundaries to lay them to rest.

The site at Ardscull was recorded by a researcher identified as O'Murethi, who, writing between 1891 and 1895, annotated an Ordnance Survey six-inch map to indicate a small square area in the corner of a field. He named it "The Dullagh", glossing the term as "burial place of unbaptised children". The field lies just outside the boundary of a very large ecclesiastical enclosure that surrounds Ardscull graveyard itself, a proximity that feels deliberate, placing the children as close to consecrated ground as unofficial burial allowed. The Ardscull area is also known for its motte, a type of earthen mound raised as the base of a Norman timber castle, suggesting a landscape layered with centuries of use and significance.

Today there is nothing on the surface to mark the graves. The absence of any physical trace is itself characteristic of these sites; cilliní were rarely monumentalised, and many survive only because local memory or an annotated map preserved the name.
