Sister Stella Marko, a member of the School Sisters of Notre Dame who taught in parochial schools and worked in an orphanage, died of congestive heart failure June 18 at her order's motherhouse in the Woodbrook section of Baltimore County. She was 87.
She was born Patricia Stella Marko in Philadelphia. In an autobiographical sketch, she wrote that she was enamored of the nuns whose convent was next door to her family's home. After attending public schools, she became a secretary and stenographer. In 1943, she entered the School Sisters of Notre Dame and received the religious name Sister Mary Trudberta. She later used her baptismal name.
She earned a degree in education at the College of Notre Dame of Maryland and began teaching in 1954 at St. Peter School in Libertytown in Frederick County.
Sister Stella went on to assignments at the Blessed Sacrament School on Old York Road, St. Michael's Commercial School in East Baltimore and St. Joseph Monastery Parish School in Irvington.
