The name Killofin itself carries an echo of early Christian Ireland: the prefix "kill" derives from the Irish "cill", meaning a church or monastic cell, a pattern found in place names scattered across the country wherever early ecclesiastical foundations took root.

Beyond the evidence written into the landscape and the name itself, detailed records for this particular site remain sparse. What can be said is that ruined churches of this kind in County Clare frequently have roots stretching back to the medieval period, sometimes built on or near much earlier monastic sites. They served as parish churches through the centuries, gathering generations of local families, before falling out of use and into disrepair. The surrounding ground often functioned as a burial place, and in many such sites the graves continued in use long after the building itself was abandoned to the elements.
