Born in Marlborough, she was the daughter of the late Phillip P. and Marion P. (Domingue) Russell.
She had been employed, until her illness, as a Certified Nursing Assistant working for local nursing facilities and Visiting Nurse Association, and also caring for private patients, which she truly enjoyed.
Mary loved animals, sewing and cooking, the Beatles and Michael Jackson. She was funny and had a keen sense of humor.
She is survived by her daughter, Shannon Russell of Marlborough; her sister, Sandy Nichols of Marlborough; and her nephew, Michael Hook DiMarino of N. Attleboro.
