No adults were ever laid here. The ground was reserved for unbaptised infants, children who died too soon to receive the sacrament and who, under older Catholic doctrine, could not be interred in consecrated parish cemeteries. These places, known in Irish tradition as cillíní, are found across Ireland, often unmarked and easy to miss, their locations preserved less in stone than in local memory.

The burial ground near Glenderry is mentioned in several pieces of folklore gathered from local schoolchildren in the late 1930s as part of a nationwide collection scheme. Accounts from both Glenderry School and Booleenshare School place the site to the north of St Macadaw's holy well. One account names it within the wider landscape of the Parish of Ballyheigue, which the children described as having three distinct graveyards: the main parish cemetery at Ballyheigue, a ground at Keelmacada reserved for the Corridon family and infants, and a separate place called Glendahalan where, the account notes plainly, "no adults buried but infants who die immediately after birth." The Corridon family appear repeatedly in these accounts; their association with the burial ground at Kerryhead is accompanied by the detail that a light is said to appear there whenever one of the family is about to die, and that a tomb-shaped stone covering a bishop's grave cannot be permanently removed, returning of its own accord before morning. Whether the children's burial ground is the same ground as this Corridon family site, or an adjacent one to the north of it near the holy well, the accounts leave slightly ambiguous, though the connection to St Macadaw's well is consistent across more than one telling.

The site lies close to St Macadaw's holy well, which is itself a named landmark in the area. Visitors looking for the burial ground should expect no formal signage or monument; cillíní were typically unmarked, or marked only with small uninscribed stones, and their boundaries can be difficult to read on the ground. The proximity to the holy well provides the most reliable point of orientation the folklore accounts offer.
