Mary Theodosia Mug (1860-1943) was an author, poet, composer, and the biographer of Saint Mother Théodore Guérin. After almost 90 years of controversy, Sister Mug's miraculous healing from cancer was finally accepted in 2006 by the Holy See as Guérin's first miracle for sainthood. Sister Mug published books and also composed music under the pseudonym H. Maery or Helen Maery, although she did occasionally use her religious name. Source: Wikipedia (en)
