Columbkille, also known as Columba, is one of the great figures of early Irish Christianity, a sixth-century monk from Donegal who founded the celebrated monastery on the Scottish island of Iona and left an enormous imprint on the religious culture of northern Ireland and Scotland. His name turning up attached to a church in Kilkenny, well to the south of his usual sphere of influence, is the kind of small geographical anomaly that tends to reward curiosity.

Dedications to Columbkille do appear across Ireland in places far removed from his primary associations, often reflecting the reach of his cult during the early medieval period, when local communities attached their sacred sites to widely venerated saints. A church bearing his name in this part of Leinster may point to an early foundation, possibly pre-Norman, though without more detailed records it is difficult to say more about the specific history of this particular site. The townland name itself preserves the dedication, which is often how these connections survive long after the physical fabric of an early church has disappeared or been rebuilt beyond recognition.
