Petronille was born in 1958, and was married in 1979. Petronille became a widow in 1997 when she lost her husband to the civil war that ensued after the genocide. After his death she worked in the gardens. However, there was not consistent work and could not provide for her family at all times. Other work was very difficult to come by.

Petronille was hired by True Vineyard Ministries in April 2012. Since she has been employed with True Vineyard, Petronille is very grateful to God for her life now. She is a professed Christian and attends the Catholic Church.
