'To the memory of Mary Morgan, who young and beautiful, endowed with a good understanding and disposition, but unenlightened by the sacred truths of Christianity become the victim of sin and shame and was condemned to an ignominious death on the 11th April 1805, for the murder of her bastard child. Rous'd to a first sense of guilt and remorse by the eloquent and humane exertions of her benevolent judge, Mr. Justice Hardinge, she underwent the sentence of the Law on the following Thursday with infeigned repentance and a furvent hope of forgiveness through the merits of a redeeming intercessor. This stone is erected not merely to perpetuate the remembrance of a departed penitent, but to remind the living of the frailty of human nature when unsupported by Religion. Thomas Bruce Brudenell Bruce, Earl of Ailesbury.'
