That fact alone makes it worth attention. The tapering graveslab, likely medieval in origin, was first carved with an incised cross rising from a calvary of three steps, flanked by the tools of a ploughman's trade: a plough sock on the right side of the cross stem and a coulter on the left. These occupational symbols were a recognisable medieval convention, a way of marking a person's craft or status in stone rather than words. Someone who came after, however, had little use for the original imagery. The head of the cross was chiselled away, and the upper portion of the slab was repurposed as a memorial inscription.

The scholar R.A.S. Macalister recorded the stone in 1913 and was the first to note its dual life. The later inscription reads: 'Lord have mercy on the Soul of Mary Kennamore wife to Iohn Hanly who died Nov 1792 Aged 49 years.' Mary Kennamore's memorial, cut into a stone that had already served someone else entirely, was positioned in front of the westernmost wall monument along the south wall of the nave. The recycling of older funerary stonework was not unheard of in post-medieval Ireland, particularly where good-quality worked stone was scarce or where the original occupant had been long forgotten. What survives here is an accidental palimpsest, two lives and two eras compressed into one object.

When inspected in October 2018, the slab could no longer be located in the position where it had previously been recorded. Whether it was moved, removed for safekeeping, or simply obscured is unclear. Its current whereabouts, if it still exists, remain unknown.
