The slab once bore a name, Wennhane O'Hullichan, carved in Lombardic characters, a rounded, decorative script common to medieval monumental work, asking that God have mercy on his soul. It is a small, quiet survival, or rather a quiet dispersal, of a personal memorial that was already seven centuries old when someone last made a proper record of it.

The scholar and priest William Carrigan first noted the slab in 1888, describing it as coffin-shaped and then almost perfect: roughly six feet long, tapering from just over two feet wide at the head to around a foot at the foot. When he returned in 1896, he found it broken into several pieces lying scattered about the chancel. He gathered the fragments and pieced together enough of the Latin inscription to reconstruct its meaning. The text, in the formulaic style common to medieval memorial slabs, reads in full as "Here lies Wennhane O'Hullichan, on whose soul may God have mercy." When a field visit was made in 1987, the slab was not recorded, though it is considered likely that the pieces remain somewhere within the church and its surrounding graveyard, dispersed and perhaps partially buried or overgrown, waiting for someone with enough patience to look.
