The children's burial ground at Letter More, in County Galway, is one such place. These sites were typically chosen with care by local communities, often near ancient earthworks, boundary ditches, or the ruins of early Christian enclosures, locations that carried their own quiet sanctity outside the formal parish system. The grief encoded in them is private and communal at once, passed down through families rather than recorded in any official register.

The practice of using cillíní persisted in Ireland from the medieval period well into the twentieth century, a reflection of how canonical restrictions on burial intersected with rural custom and the practical realities of loss. Unbaptised infants occupied an ambiguous theological position, excluded from heaven under the doctrine of limbo, and so their burial required places that were neither fully secular nor formally sacred. Letter More, a townland in Connemara, sits within a landscape where such sites are not uncommon, the west of Ireland having preserved an unusually dense record of early ecclesiastical remains and associated folk burial traditions. The specific history of this particular ground, its age, the community that maintained it, and the local customs attached to it, remain to be fully documented.
