A native of Browns Valley, she was born Mary Frances Hite, the daughter of the late Robert and Mary Margaret Knott Hite. Sister Theresa Margaret had a great love for small children, and was a very prayerful person, with a devotion to the apparitions of the Blessed Mother at Medjugorje. She was very artistic, making beautiful thank you scrolls for the sisters.
An educator for 47 years, she taught in Owensboro at Blessed Mother School in 1953. She also ministered in Mayfield, Paducah, and Leitchfield, in the Archdiocese of Louisville, and in Missouri and Nebraska. She retired to Mount Saint Joseph in 1994.
Survivors include nieces and nephews, and the members of her religious community.
