Marguerite d'Youville died in 1771 at the General Hospital. In the next century, her status continued to increase, as people cited prayers for her intervention in aiding them. After her spiritual writings were approved by theologians on February 1, 1888, her beatfication process was formally opened on April 28, 1890, and she was granted the title
Servant of God. She was declared
Venerable by
Pope Pius XI on June 16, 1931. The review process for canonization included review of a medically inexplicable cure of
acute myeloid leukemia in a patient after relapse, after prayers to Sister Marguerite. The woman in the case is the only known long-term survivor of this disease in the world, having lived more than 40 years from a condition that typically kills people in 18 months. Numerous Catholic churches, schools, women's shelters, charity shops, and other institutions in Canada and worldwide are named after St. Marguerite d'Youville. Most notably, the Catholic institution of higher learning,
D'Youville University in
Buffalo, New York, is named after her. The
D'Youville Academy at
Plattsburgh, New York was founded in 1860. It was listed on the US National Register of Historic Places in 1978. Lady Jetté, wife of Sir
Louis-Amable Jetté, at one time Lieutenant Governor of Quebec, wrote a biography of Marie-Marguerite d'Youville. ==Final resting place==
