The inscription reads: ORA PRO CONSERVO PATRICIO NEILAN 1735, which translates roughly as "Pray for the fellow servant Patrick Neilan, 1735." The word conservus, meaning a fellow slave or fellow servant, is an unusual choice for a commemorative inscription, carrying an early Christian humility about it that sets this piece apart from the grander memorial tablets one might expect to find in an Irish parish church.

The plaque itself is modest in scale, measuring roughly half a metre in height and a metre across, cut from limestone and bearing its text in raised letters. It dates to 1735, placing it in a period when Catholic devotional practice in Ireland was operating under the constraints of the Penal Laws, and formal monuments of any kind were relatively rare in Catholic ecclesiastical settings. The name Patrick Neilan is otherwise unadorned here, with no title, no family genealogy, and no record of deeds or office. The appeal is simply to prayer, framed in the language of shared servitude before God.
