Giulia Valle was born in
Aosta on 26 June 1847 to Anselmo Valle and Cristina Dalbar; she was the oldest sibling of Vincenzo however her parents had lost two sons before her birth. Valle was
baptized hours after her birth in the Church of Saint Orso in the names of Maddalena Teresa Giulia. She worked in her parents' milliner shop during her childhood. Her mother died when she was four in 1851 and she was sent to live with paternal relatives in Aosta (her grandfather and an unmarried aunt) and then with maternal relations in
Donnas. She assumed the religious name of "Nemesia" upon her solemn profession on 15 October 1873. After her profession, she was sent to the Institute of Saint Vincent in 1866 at
Tortona and taught general studies to children and the French language at the high school level. She aided
Luigi Orione and also provided shelter to
Teresa Grillo Michel and was later assigned as the Mistress of Novices at
Borgaro Torinese and spent the remainder of her life there where she led 500 new sisters into religious life. In the autumn of 1916 her health took a sharp pitfall and declined to the point where on 11 December she contracted severe
pneumonia. She died a week later on 18 December 1916 at 9:10 pm; the room filled with a sweet perfume of roses and violets when she died. She was buried in the church of the institute in Borgario Torinese. ==Beatification==
