What draws attention is the name itself: Kilmihil derives from the Irish Cill Mhichíl, meaning the church of Michael, pointing to an early ecclesiastical foundation dedicated to the Archangel Michael that once anchored this community long before the surrounding village took its present shape.

Parish graveyards of this type in County Clare frequently occupy ground that was sacred well before the medieval period, with early Christian foundations sometimes overlying sites of even older significance. The presence of a graveyard here suggests the former existence of a church or chapel, the physical structure of which may have long since disappeared, leaving only the burial ground as evidence of the settlement's religious past. In many such cases across the west of Ireland, fragments of carved stonework, early grave slabs, or the outline of a vanished nave can still be detected beneath the grass or in the field boundaries nearby.
