Louis Guillet dit St Marc was married to Marie-Catherine Trottier, daughter of Jean-Baptiste and Geneviève Lafond. Two of Marie's sisters were nuns in the Congregation de Notre Dame. Catherine was four years older than her sister Marguerite. They both received their training under the guidance of Marguerite Bougeoys. They joined the order in 1694, Catherine at the age of 20 and Marguerite at 17. Marguerite enjoyed better health than her sister and in consequence was sent as a missionary to Chateau-Richer. A year later Catherine was sent to the mission of the Holy Family on the l'ile d'Orléans. Three years later they made their final vows; Catherine became Sister Saint Francois and Marguerite - Sister Saint Joseph.
In 1705, Marguerite who enjoyed her post as teacher was asked to fill the post of Depositary (trustee) for the Congregation. She would remain in this position till she became Mother Superior in 1722. In 1713, she was involved with the building of new schools and dormatories. She had occassion at this time to deal with Sister Le Ber whom she wrote was full of encouraging words etc. In 1715, she was asked to write about Marguerite Bougeoys, the founder of the congregation. In 1722 she was elected to take over the post of Mother Superior from Marguerite Lemoyne dite du Saint-Esprit, who in turn became mistress of Novices. On February 24, 1726 Father Pierre Remy died. Marguerite Bourgeoys had expressed her great confidance in this man. He had been superior and benefactor of the community and at the same time curé of Lachine. It was his flock at the time of the Lachine massacre in 1689. In 1694, the Saint Anges de Lachine registers dealt with the burial of several victims. One of the 3 witnesses on the documents is Guillaume Daoust, our paternal ancestor, who is designated as cantor and verger. The other witnesses were Jean Paré and André Rapin, the ancestor of Helene Lamarche.
One important event during sister Saint Joseph's years was the formation of a mission to Fort Louisbourg in 1727. When her term as Mother Superior was over, Marguerite and a Sister Saint-Arsène set off for Fort Louisbourg in the summer of 1732. Before their departure, land and a house had been procured for the sisters in Louisbourg. They were barely settled into their new home when they were overwelmed by the number of children seeking instruction. Since they also had to maintain the house, the work was too demanding. They wrote to Sister Saint Barbe ( this new Mother Superior was Marie-Elisabeth Guillet, daughter of Mathurin Guillet, son of Pierre Guillet dit Lajeunesse) requesting additional help. Two sisters were sent who arrived in 1734. A domestic, Mlle Paré came with them. Two years later, she joined the congregation. Sister Marguerite Trottier dit Saint Joseph worked at the mission of Louisbourg for eleven years. By that time she was exhausted and requested a return to Ville Marie which was granted. Unfortunately, she passed away, aboard ship near l'ile d'Orlean. She was 70 years old. She had been in the Congregation 54 years.
At the Ramesey museum one can see the bell that chimed at Fort Louisbourg during the years Marguerite was there.
