The Sisters use the postnominal initials of SSA The congregation was founded in Turin in 1834 by Carlo Tancredi Falletti di Barolo (1782–1838)[1] and the Servant of God Juliette (Giulia) Colbert, TOSF (1785–1864), the Marchese and Marchioness of Barolo.

The childless couple had opened their own palace to the children of the streets of the city, and were seeking to provide for their education.

The volunteers they had recruited to help with this mission agreed to embrace the consecrated life.

Other women joined the congregation and they began to serve in various towns and villages throughout the Piedmont region and then elsewhere in Italy.

They now serve in Albania, Argentina, Brazil, Cameroon, Mexico, Peru, the Philippines and the United Kingdom.
