St. Louise De Marillac (1591-1660) was born in Paris, France to a noble family and received her education at a Dominican convent. Her mother died shortly after her birth, and her father when she was sixteen years of age. It was then necessary for her to decide her vocation, and being dissuaded from entering religious life by her spiritual director, as was her desire, she married and bore a son. Later she worried that she had rejected a divine call to the religious life, and vowed that should her husband die, she would not remarry. Two years later her husband died after a long illness. During this time she met a holy priest, St. Vincent de Paul, and placed herself under his spiritual direction. Through his influence she worked among the poor and disadvantaged in Paris, and co-founded the Sisters of Charity with him in 1642. After writing their rule of life she traveled around France establishing her new religious order to work in hospitals, orphanages, and other institutions that aided the poor. She was especially gifted at spiritual guidance and served as the superior of the Sisters of Charity in Paris until her death. St. Louise De Marillac is the patron saint of social workers, the sick, widows, and against the loss of parents. Her feast day is March 15th.
