The placename itself points the way: Kiltivna derives from the Irish, with "cill" denoting an early ecclesiastical enclosure or church site, the kind of foundation that in Ireland frequently predates the Norman arrival and often marks the location of a forgotten early medieval community. Graveyards attached to such sites have a habit of accumulating centuries of use, layering the early Christian period over whatever came before, and then continuing into the post-medieval era long after the original church fabric has vanished entirely.
