The graveyard that had served the parish for centuries had been levelled by the landowner, a Mr. Gubbins, within whose demesne it lay. The Ordnance Survey Letters noted that year that the burial ground was "not much in use", which reads now as something of an understatement, given that the ground itself had been cleared away. What survives today is largely a name on a map and a scatter of references in antiquarian records.

The place name has a long documentary trail. Thomas Westropp, recording early in the twentieth century, traced it back to 1287, when it appeared as "Kilfroys" in an inquisition connected to Thomas de Clare. By 1302 it was listed as "Kilfrussce" in the Grene Deanery, and in 1318 a certain Jacob Stak was recorded in the Plea Rolls as having robbed the church, an incident that at least confirms the building was substantial enough to be worth targeting. Later spellings drift through "Kylfrushe" in 1586 and "Killfruishe" by 1615, at which point a marginal note indicates the site was already considered ruinous. Associated with the church was a holy well, Tobercolman, a type of sacred spring commonly dedicated to an early Christian saint and frequently found beside ecclesiastical sites of early medieval origin.

There is little left to find on the ground. The site falls within what was once the Gubbins demesne, and the levelling of the graveyard in the nineteenth century will have erased much of whatever remained. The well, Tobercolman, is recorded separately in the archaeological inventory and may be traceable, though its current condition is not documented in the available sources. Anyone with a particular interest in vanished ecclesiastical landscapes of County Limerick might treat Kilfrush as one point in a broader study of the area, cross-referencing the Ordnance Survey Letters and Westropp's surveys rather than expecting much from a visit to the field itself.
