Mary Rose was born March 18, 1915, the daughter of John and Betty Husk Lindauer, a German family who lived in Newman, Ky. Her formal education began at St. Peter of Alcantara School in Stanley. She continued there through her graduation from high school. Mary Rose spent several years in the business world of Owensboro. Her life was happy but she was not satisfied with what the business world offered. At the age of 23, she entered the novitiate at Mount Saint Joseph. After her postulancy, Mary Rose received the Ursuline habit on August 14, 1939, and was given the name Sister Charles Mary.
After profession of temporary vows in 1941, Sister Charles Mary was assigned to Howardstown, Ky., where she taught the first four grades at St. Ann School and served as organist for the school and parish. After 11 years there, she taught in other public and parochial schools in Kentucky teaching junior high or high school students: Lebanon (St. Charles High School), St. Alphonsus, Browns Valley, Buechel, Radcliff, Whitesville (Trinity High School), Mount Saint Joseph Academy, and Paducah (St. Mary High School). In 1973, she was assigned to Florissant, Mo., to open St. Angela Merici Elementary School. She served there as principal and added a grade each year until the school included all eight grades. She was missioned to Seven Holy Founders School in Affton, Mo., where she served until 1989 as principal. (In 1980, while at Seven Holy Founders, she returned to her baptismal name, Mary Rose).
Sister Mary Rose moved back to Kentucky the summer of 1989 to serve as pastoral minister at St. Anthony, Browns Valley. She was diagnosed with cancer of the brain in October and returned to the Motherhouse infirmary. During her confinement of less than four months, she edified everyone by her patient and contented living following a schedule of rest, prayer, and exercise. Death came to Sister Mary Rose on February 24, 1990. With Fathers Paul Keragieter, OSM, Donald Kentley, OSM, and John Vaughan as concelebrants, Father Jack Topper, OSM, celebrated the funeral Mass on February 27. With her nephews and former pupils serving as pallbearers, her remains were carried to the convent cemetery for burial.
