This one, propped against the east wall of the north transept in Fethard's abbey graveyard, repays closer inspection. Measuring just over two metres in length and nearly a metre wide, it is carved with a seven-armed segmental-headed cross in relief, its terminals finishing in fleur-de-lis. The cross-head carries floral motifs in each of its four central sections, and a three-barred knop, a decorative boss or swelling, appears both at the base of the cross-head and again at the base of the shaft, which itself rests on a carved pillar-base. To one side of the shaft, the letters IHS are raised in Black Letter script, the Gothic lettering typical of late medieval stonework. To the other side sits a heraldic shield in an ogee-based rectangle.

That shield is where the slab becomes genuinely interesting. The arms depicted show a chief indented debruised by a bendlet, which in heraldic terms means a horizontal band across the top of the shield, cut with a zigzag lower edge and overlaid by a diagonal stripe. Researcher Crotty, writing in 2012, suggested this device belongs to the Dunboyne branch of the Butler family, one of the most powerful Anglo-Norman dynasties in medieval Munster, though the Power family of County Waterford bore a similar charge and cannot be entirely ruled out. The faded inscription running along the top, sinister, and base borders of the slab settles the matter of who commissioned it, if not which family they were allied to. As translated by Knowles in 1903, it reads: here lie Thaddeus Owns Meagher and Honora Keeghan, his wife, who erected this monument before their death, A.D. 1540. The couple had their tomb made while still alive, a common enough practice among people of means in late medieval Ireland, intended to secure prayers for their souls and to leave a visible mark on the community around them. The lower corner of the slab has since broken away, and some chipping is evident, but enough survives to read the craft and the intention clearly.
