LEWISTON – Sr. Aurelie (Marguerite) Tetreau, 90, passed away at the Marguerite d’Youville Pavilion in Lewiston on Thursday, March 8.

Marguerite was born in Sanford on Dec. 22, 1916, the daughter of Alfred and Aurelie (Langlois) Tetreau. She received her elementary and secondary education certificates from St. Ignatius Ursuline School in Sanford.

In 1936, Marguerite entered the Ursuline Sisters’ Novitiate in Waterville, where she made her religious profession in 1938, under the name of Sr. Aurelie.

As a young professed Ursuline, she pursued college courses at Saint Joseph’s College in Maine and later at Saint Michael’s College in Vermont, where she obtained a bachelor’s degree. Her teaching career spanned almost a half century in Catholic parochial elementary schools in Maine: Lewiston, Chisholm, Skowhegan, Sanford, Waterville and Brunswick, where she taught for more than 30 years at St. John’s Catholic Elementary.

Her former students remember her as a dedicated, nurturing teacher. Throughout most of her religious life, Sister also served her Ursuline community as local treasurer.

Sister is survived by her sisters, Laurette Bald and her husband, Armand, of Somersworth, N.H., Claire Brandt of Sonoma, Calif., Adrienne LeBlanc and her husband, Rene, of Sanford and Louise Pepin and her husband, Albert, of Biddeford.

She was predeceased by three brothers, Emile, Paul and Henry; and five sisters, Antoinette Chambers, Rose DesRosiers, Delia White, Victorine Allaire and Bertha Laflamme.
