Benedictine Sister Mariella (Carol) Hathorn, 81, died unexpectedly Feb. 7 at St. Joseph Court-St. Scholastica Monastery.

Sister Mariella was born in Pennsylvania and entered the Benedictine community at St. Joseph Monastery, St. Marys, Pennsylvania, in 1957. She made her first profession in 1959 and her final vows in 1962. Sister Mariella had a 28-year career in education in Pennsylvania, serving mostly middle grades as well as in administration as principal. In 1987, she was elected prioress of St. Joseph Monastery and served two terms there.

She then spent a sabbatical time at St. Scholastica Monastery in Chicago. During the years at St. Scholastica, Sister Mariella discerned a call to transfer her stability to St. Scholastica Monastery in Chicago and requested permission to do so in 1998.

Her first assignment in Chicago was as director of the St. Joseph Court infirmary.

She is survived by her sisters, Jean Klaiber and Sally Lanzel.
