That much is certain. The details beyond that, the name it goes by, the saint to whom it may be dedicated, whether offerings or rags are still tied to a nearby bush in the old custom, remain unrecorded in any publicly available source. Holy wells are among the most widespread yet least uniformly documented features of the Irish landscape, numbering in the thousands, and a great many persist quietly in fields and hedgerows with no signage and no ceremony beyond the occasional local who still knows they are there.

The tradition of venerating such wells predates Christianity in Ireland, rooted in a much older sense that certain springs and water sources held curative or protective power. When Christianity arrived, many wells were absorbed into the new faith, rededicated to saints and worked into the calendar of pattern days, local festivals tied to a particular saint's feast on which people would walk a prescribed circuit, pray, and sometimes drink or bathe in the water. Clare is particularly well supplied with such sites, given the county's deep seam of folk religious practice and the relative resilience of rural devotion there into the modern period. Whether the well at Ballycroum ever drew pattern-day crowds, or was always a quieter, more private kind of place, is simply not known from what survives.
