DEATHS: Wednesday evening, at eight o'clock, at the house of her husband, on the Quay, in her 28th year, Mrs Alicia Meagher, wife of Thomas Meagher jun. Esq., and daughter of the late Thomas Quan, Esq.. This amiable and excellent lady (who was lately delivered of twin daughters, one of whom has since died) was an object of the warmest regard to all who knew her, being as much and as justly admired for her numerous and sterling virtues, as she was universally loved for her kind, benevolent and truly charitable disposition. To her respected relatives and connections, who had the best opportunity of appreciating her worth and goodness, and particularly to her tenderly attached partner, her premature dissolution is a source of the most poignant affliction - an affliction in which all classes of the Public sincerely sympathise. By the poor, to whom she was a constant and generous, though unostentatious benefactor, her loss will be most sincerely felt and deplored.
