    Sister Mary Trinita was my seventh grade teacher at St. Francis de Sales School in 1952-53. In perusing the internet, I found her obituary. Sister Trinita was a wonderful woman who was always able to make her students feel as though they were very special. If I am not mistaken, Sister Trinita, in her pre-sisterhood days as Mary McIsaac, worked at the old Charlestown Navy Yard as a co-worker with my dad. It has been nearly seventy years now since I was one of her many students, but her memory lives with me. She had to be special to still be part of me. RIP Sister.

    Sr Trinita was the Principal at Sacred Heart High School in East Boston. I was Class of 1967. She was my chemistry teacher. She was our Guidance Counselor. She was our senior year home room teacher.

    I always liked and respected Sr Trinita. She was incredibly smart and a no-nonsense person, traits I still admire. There was a tad of healthy fear thrown in for good measure. I learned a lot from her. Thanks very much, Sister. May you Rest In Peace.
