The Sisters of the Holy Family are an apostolic, international congregation, located on four continents and in thirteen countries. There are five provinces in the United States. A Sister of this congregation is identified by the initials CSFN (Latin for "Congregatio Sororum Sacrae Familiae de Nazareth"; English: "Congregation of the Sisters of the Holy Family of Nazareth") placed after her name.
The Congregation of the Holy Family of Nazareth was founded in Rome, Italy in 1875 by Frances Siedliska, a Polish noblewoman. From Rome, the Congregation spread quickly.
In 1885, Mother Mary of Jesus the Good Shepherd and eleven sisters journeyed to Chicago, Illinois, where they had been invited to minister to the needs of Polish immigrant children and families. There they staffed two schools and an orphanage. The Congregation soon expanded its services in the Midwest. They continue to serve throughout Illinois, Indiana, Pennsylvania, New York, Connecticut, Texas, Michigan and Ohio.
The sisters opened their first hospital in Poland in Wadowice in 1897.
The sisters have served in schools, and in child care services, care of the elderly, retreat work, and in parish, prison and youth ministry.
Sisters continue to be engaged in various areas of healthcare and presently minister as hospital chaplains, nurses, therapists, and lab technicians, attending to the sick, the elderly and the infirm.
As of 2015, there are over 1,300 members in Australia, Belarus, England, France, Israel, Italy, Lithuania, the Philippines, Poland, Puerto Rico, Russia, Spain, Ukraine, and the United States of America.
