[1] By turns a nun, reporter, novelist, author of poetry and youth fiction, Saint-Pierre was a global voyager and hunter travelling across North and South America and Australia who wrote enthusiastically about her adventures.
She joined a convent associated with the Oblates of Saint Francis de Sales in Brittany, located in northwestern France, and remained a nun for 15 years.
To feed her need to travel, she left Brittany alone for North America - United States and Canada - where she renewed her passion for hunting (reportedly, she had received her first shotgun for her tenth birthday).
[2][3] In 1910, at 38 years of age, she married Joseph-Marie Potiron de Boisfleury, but the marriage failed, lasting only three months.
[5] In 1930, she was admitted to the community in Brittany known as Goursez Vreizh as a bard under a new name Brug ar Menez Du (Heather of the Black Mountains).
