The inscription uses the phrase "Eques Albus", meaning the White Knight, a hereditary title held by a sept of the Fitzgibbon Geraldines, and records that a Johannes, his son Edmundus, and a Mauritius son of the said Edmundus, along with many others of the same family, were buried at this spot. The slab opens with the Christogram IHS, standard on Catholic funerary monuments of the period, and the rest of the text follows in neo-classical Roman capitals rendered in the manner typical of seventeenth-century Irish memorial carving.

The White Knights were a cadet branch of the Geraldines, the great Anglo-Norman family whose various lines dominated Munster for centuries. The title itself was one of three hereditary knighthoods associated with the Earls of Desmond, alongside the Black Knight and the Knight of the Valley. The memorial slab at Kilmallock is recorded in the Urban Survey of County Limerick (Bradley et al., 1989), which describes it as a commemorative slab dating to the seventeenth century. It was also noted in the publication Memorials of the Dead, volume one, which appeared between 1888 and 1891. The inscription, though partially legible in the surviving record, makes clear that the monument was erected in memory of the Geraldine lineage known commonly as the White Knights, and that multiple generations of the family were interred at the same location.

Kilmallock itself is a medieval walled town in south County Limerick, and it retains a considerable number of surviving medieval and early modern structures, including a Dominican friary and stretches of town wall. Anyone seeking the memorial slab should consult local heritage resources before visiting, as the precise current location and condition of the stone are not specified in the available survey notes. The Latin text, where legible, rewards close reading, since the formula used to describe the family, "qui vulgo vocantur Eques Albus", meaning those commonly called the White Knight, reflects a self-conscious effort to fix the identity of an old Gaelicised Norman family in stone at a time when such identities were under considerable political pressure.
