These carved fragments, almost certainly salvaged from an earlier church that once stood on the same low rise, are now flush with the ground, serving the dead in a function their makers never intended. It is a quiet kind of recycling, and it gestures at a much longer history of worship on this site than the current rubble limestone walls might suggest.

The parish name offers its own layered record. In Irish it is Cill Dha Chomóg, meaning the church of St Da-Chomóg, though a 1411 papal appointment refers to it instead as the vicarage of St Frigius's Killdacanog, a discrepancy that reflects how place-names and their associated dedications could shift across centuries and languages. That 1411 document names one Bernard Macmurkerchaid as vicar; by 1542 the rectory had been leased to a Walter Tirrell of Dublin, and in 1623 a Nathaniel Hollington was appointed to the vicarage. The church also appears on an early seventeenth-century map of Rathcline barony, confirming it was a recognised landmark well before the current structure took shape. The building itself is probably of late seventeenth-century date, though it was substantially remodelled in the mid-eighteenth century, when five large round-headed windows were inserted and a structure added to the west end, either an entrance porch or the lower stage of a tower, a form common in Church of Ireland buildings of the period. A blocked doorway at first-floor level in the west gable points to a gallery that no longer exists. Interior features from the same remodelling phase include moulded cornices along the north and south walls, a memorial plaque dated 1749, and a wall-tomb near the east end of the north wall that retains a quiet sense of occasion even now.
