That combination, an officially recognised site with almost no surviving detail in circulation, is itself a small curiosity. Many such graveyards in rural Ireland mark the sites of early medieval parishes or ecclesiastical enclosures that have long since vanished above ground, leaving only the burial ground as evidence that something older once stood nearby.

The place-name Killaspy likely derives from the Irish, with the element "kill" or "cill" indicating an early church or cell, a common prefix across Leinster that points to Christian settlement in the period roughly between the fifth and twelfth centuries. Graveyards of this type often continued in use long after the founding church crumbled or was abandoned, with local communities maintaining burial rights across generations. In some cases, traces of enclosure banks, carved stonework, or even the outline of a building foundation survive within or beside the burial ground, though without detailed fieldwork records it is impossible to say what, if anything, remains visible at Killaspy.
