Catherine McAuley was born in Dublin, Ireland, in 1778. After the death of her mother and father, she served as household manager and companion to the Callaghans, an elderly, wealthy Protestant and Quaker couple. During those years, she became increasingly called to devote her life to the service of the poor, sick, and uneducated, particularly after she had bitter experiences trying to find shelter for abused servant women and homeless girls.
After long illness, and aided by McAuley’s presence and prayer, Mrs. Callaghan passed in 1819, and just three years later, Mr. Callaghan died in 1822, naming Catherine McAuley the sole residuary legatee of his estate and life’s savings.
In 1824 Catherine used her inheritance to build a large house for poor servant girls and homeless women on Baggot Street, in a fashionable section of southeast Dublin. The House of Mercy opened on September 24, 1827, on the feast day of Our Lady of Mercy.
Catherine desired for her works to remain unaffiliated with any religious congregation to avoid aspects of convent life and restrictions she thought religious life would impose on the works of mercy to which she felt called. In 1829-1830, however, she realized the long-term future of the works of mercy she had begun were dependent on her willingness to found a new religious congregation, and so, in 1830 the first Sisters of Mercy took their vows.
The Sisters of Mercy, unlike those religious orders before them, were not cloistered, as McAuley fervently believed in the need for action and an active presence in the community.
Over the next ten years, the works of the Sisters of Mercy spread throughout Ireland and England, eventually making its way to the United States and beyond.
