Azélie-Marie Guérin Martin was a 19th-century French laywoman and businessperson who lived in Saint-Denis-sur-Sarthon and Alençon. She is primarily remembered as the mother of several religious women, most notably Saint Thérèse of Lisieux. After being unable to enter a convent due to health issues, she became a successful lacemaker. She married Louis Martin, and together they raised a family characterized by deep religious devotion. In 2015, she and her husband became the first married couple in the history of the Catholic Church to be canonized together.
