That much is certain. The details beyond that, the patron saint associated with it, the pattern days once observed there, the local cures attributed to its waters, remain unrecorded in any publicly available form.

Holy wells are among the most persistent features of the Irish landscape, pre-Christian water sources that were absorbed into Catholic devotional practice over centuries and often dedicated to local saints whose cults survive in place names long after the wells themselves fall into disuse or obscurity. Clare alone contains dozens of them, each with its own accumulated folklore, its own traditions of rounds or patterns, sometimes marked by a rag tree hung with offerings of cloth, or a small shrine tucked into a drystone recess. Kilcarroll, a quiet townland whose name derives from the Irish for the church or enclosure of Carroll, sits within this broader tradition. Whether the well here retains any active devotion, or has simply reverted to a spring in a field, is not known from any source currently in the public domain.
