Starting in the mid 1980s, Mrs. DiStefano taught Spanish at schools including St. Monica School in Berwyn.
In the late 1990s, she organized a Spanish program for parents at New Eagle Elementary School in Tredyffrin. She ran that class until 2005.
Born in Havana, Mrs. DiStefano arrived with her immigrant family in New York in 1940. She graduated in 1951 from St. Walburga's Academy there.
She earned a bachelor's degree in Spanish from the Fordham University School of Education in 1955. She did graduate work in Columbia University's department of philosophy.
Mrs. DiStefano could trace her ancestry to Spanish and English settlers in the New World. She was a devoted Catholic and a registered Republican who voted for John F. Kennedy and against Ronald Reagan, her son said. She was a member of the Daughters of the American Revolution.
In addition to her son Joseph, she is survived by her husband of 52 years, Renato T. Jr.; sons Andrew and Richard R.P; a daughter, Victoria Mahalsky; a brother; and 13 grandchildren.
