Born in Honolulu, Hawaii, Sister Mary Hugh Mauldin was part of a Navy family. A Sister of Mercy for 65 years, she ministered in education, from elementary school through college.
Sister Mary Hugh taught in several elementary schools staffed by the Sisters of Mercy and at Charlotte Catholic High School in North Carolina. In addition, she taught math and theology for 23 years at Limestone College in Gaffney, South Carolina. She was the first woman religious to hold a faculty position at the college—a 92-mile round trip from her residence at Sacred Heart Convent in Belmont, North Carolina. While at Limestone, she earned its Fullerton Teaching Award four times, had a yearbook dedicated to her and was a commencement speaker.
Once she retired from the classroom, Sister Mary Hugh ministered as an adult religious educator and gave talks in parishes in the Charlotte Diocese. In addition to teaching, she enjoyed playing tennis, working crossword puzzles, doing beautiful cross-stitch, reading and gardening. She was committed to music, especially liturgical music, and was director of liturgy at Sacred Heart Convent.
