A native of Curdsville, she was the daughter of the late Matthew and Elizabeth Sauer Byrne Greenwell.
An educator for over 50 years, Sister Mary Clement believed that even the most unlikely learner could become a good student. She taught until 1978, when she began a ministry of outreach and tutoring in Louisville, where she served until retiring to the Motherhouse in 1989. She loved playing cards, and has likely already started a game in heaven.
Sister Mary Clement taught in Owensboro at St. Joseph High School (1929-30), Blessed Mother School (1973-74), and Immaculate School (1974-76). She also taught at St. Anthony, Peonia (1956-58), in the Archdiocese of Louisville, in Missouri and New Mexico.
Survivors include nieces and nephews, and the members of her religious community.
