No names, no dates, no inscriptions of any kind. What fills this small sacred enclosure is the accumulated weight of grief kept quietly outside the bounds of formal Catholic burial, generation after generation.

The church is known locally as Teampull na Dithreabhaigh, and within it lies a cillíneach, a term used across Ireland for unconsecrated burial grounds set aside for unbaptised children. Catholic doctrine, as it operated for centuries in Ireland, held that infants who died before baptism could not be interred in consecrated ground. Families responded by burying these children in liminal places, old ecclesiastical sites, boundary ditches, or the margins of fields, places that carried a kind of inherited holiness outside the official church. A cillíneach (sometimes anglicised as "killeen") occupies exactly this in-between territory: neither fully sacred nor entirely secular, but freighted with a particular, unspoken sorrow. At Reentrusk, the grave-markers are so numerous they occupy the entire interior of the church, their low profiles and bare surfaces recording nothing individually, but collectively marking the site as one of sustained, repeated use over a long period. The site is noted by O'Shea and Crowley, writing in 1972, confirming that local memory of its purpose had been maintained well into the twentieth century.
