Many religious communities have the term Sisters of Charity as part of their name. While some Sisters of Charity communities refer to the Vincentian tradition, and in America to the tradition of Saint Elizabeth Ann Seton those links are by no means universal. It is important to recognize that there may be no "family" or historical relationship between groups having the phrase Sisters of Charity as part of their name. The rule of Vincent de Paul for the Daughters of Charity has been adopted and adapted by at least sixty founders of religious institutes around the world in the subsequent centuries.
In 1633 Vincent de Paul, a French priest and Louise de Marillac, a widow, established the Company of the Daughters of Charity as a group of women dedicated to serving the "poorest of the poor". They set up soup kitchens, organized community hospitals, established schools and homes for orphaned children, offered job training, taught the young to read and write, and improved prison conditions. Louise de Marillac and Vincent de Paul both died in 1660, and by this time there were more than forty houses of the Daughters of Charity in France, and the sick poor were cared for in their own dwellings in twenty-six parishes in Paris. The French Revolution shut down all convents, but the society was restored in 1801 and eventually spread to Austria, Australia, Hungary, Ireland, Israel, Portugal, Turkey, Britain and the Americas.
In 1809 American Elizabeth Ann Seton, founded the Sisters of Charity of St. Joseph's, adapting the rule of the French Daughters of Charity for her Emmitsburg, Maryland community.
In 1817, Mother Seton sent three Sisters were sent to New York City to establish an orphanage. In 1829, four Sisters of Charity from Emmitsburg, Maryland traveled to Cincinnati, to open St. Peter’s Girl’s Orphan Asylum and School. In 1850, the Sulpician priests of Baltimore successfully negotiated that the Emmitsburg community be united with the international community based in Paris. The foundations in New York and Cincinnati decided to become independent diocesan congregations. Six separate religious congregations trace their roots to the beginnings of the Sisters of Charity in Emmitsburg. In addition to the original community of Sisters at Emmitsburg (now part of the Vincentian order), they are based in New York City; Cincinnati, Ohio; Halifax, Nova Scotia; Convent Station, New Jersey; and Greensburg, Pennsylvania.
