Niece to John and Josephine Duffy, and Rosemary and Bill Granger, Diane was surrounded by many cousins and enjoyed family get togethers as a young child growing up in the Bronx, NY. She was a sentimental girl who dreamed big and had an even bigger heart. She attended Cathedral High School where she met best friend, Wilma Gregg and her high school sweetheart Peter, whom she later married.

Diane and Peter, welcomed their first born daughter, Melissa whom she loved very much. Diane was a beautiful, caring, attentive, loving dedicated mother and wife who was also hard-working, generous, supportive, nurturing, and kind-hearted.
