Holy wells occupy a curious place in the Irish landscape, neither fully pagan nor fully Christian in character, having absorbed centuries of both traditions. They were, and in many cases still are, places of pattern days, votive offerings, and quiet, persistent local devotion that outlasted official religious attention by generations.

Saint Dominick is an unusual dedicatee for a rural Mayo well. The name points most likely to Saint Dominic de Guzmán, the thirteenth-century founder of the Dominican Order, whose friars established a significant presence in Connacht during the medieval period. The Dominicans were particularly active in the west of Ireland, and their influence on local religious naming, from churches to wells to townlands, was considerable. Kiltarnaght itself is a placename with ecclesiastical roots, the element "kil" deriving from the Irish "cill", meaning a church or monastic cell, suggesting this area had some form of early Christian significance long before any Dominican association.

Beyond the name and location, the documentary record for this particular well remains thin, and the details of its history, whether it was a site of regular pattern day gatherings, what offerings or rituals were associated with it, and when those practices may have lapsed, are not currently available in the public record. What can be said is that wells of this type across Mayo were rarely invented from nothing; they tend to mark genuinely old places of gathering, where the combination of fresh water, a saint's name, and local memory kept a site meaningful across many centuries.
