[1] Troncatti was from a farming family and entered that congregation in 1907; she worked as a nurse during World War I and became part of the missions in Ecuador from 1922 until her death in a plane crash in 1969.
[2][4] She attended catechism lessons in her local parish during her childhood and in obedience to her priest decided to wait until adulthood before requesting to be admitted into the Salesian Sisters.
[5] Troncatti joined the Salesian Sisters of Don Bosco on 15 October 1905 after having commenced her period of the novitiate and she later professed her vows on 17 1908 in Nizza Monferrato.
[4] In 1915 she passed a special course in nursing and used this education during World War I as she tended to ill and wounded soldiers - she also worked for the Red Cross while stationed in Varazze.
Before she turned 85 in 1968 she penned a letter to her relations back home in Brescia and said that - despite their wishes to reunite with her - her age made travel difficult and she could not leave due to her mission.
