Sister Wilhelmina Lancaster was the founder of the Benedictine Sisters of Mary, Queen of the Apostles, a convent in Gower, Missouri, about an hour outside of Kansas City. She died on May 29, 2019 at the age of 95.

Four years after her death and burial in a simple wooden coffin, her body shows no signs of decay. In Catholicism, bodies that defy the process of decay are described as "incorruptible" and are seen as signs.
