Margaret C. Sullivan
February 14, 2021


Margaret C. (Connors) Sullivan, age 88, a longtime resident of Winchester, passed away on February 14, 2021. She was the beloved wife for 57 years of the late William G. Sullivan, until his death in 2008.

Born and raised in Cambridge, MA, Peg was the daughter of the late John J. and Helene W. (Mund) Connors. She graduated from St. Mary’s High School in Cambridge, and married the love of her life, Bill Sullivan in 1951. They moved to Winchester in 1971, where they raised their family and spent many happy years.

Peg was employed as an Office Manager at Arts & Crafts in Woburn for a time, but her main priority was always her family. Her children remembered her as kind and generous, and how she always unselfishly put everyone else first. Their family Christmas parties created some of the best family memories, including all types of food, music and laughter. Peg was known as a great listener who preferred being in the background, yet she freely shared her big, loving spirit and was a fundamental figure in the lives of her family and friends.

In her spare time, Peg spent time at the Jenks Center in Winchester, where she made many friends and enjoyed yoga classes and many programs there. She also loved swimming, aerobics classes and visiting museums. An avid reader, Peg was also connected to the Winchester Public Library and volunteered her time by delivering books to the homebound.

Peg was the devoted mother of William G. Sullivan and his wife Jeanne of Reading, Helene T. Sullivan of Billerica, Brian L. Sullivan and his wife Joanie of Chester, NH and the late Michael Sullivan and his surviving wife Kathleen, of Andover. She was the cherished grandmother of Christopher and Michael Sullivan, Connor and Luke Sullivan, Jeff, Laura and Andy Beckford, Brian “Chip” and Spencer Sullivan, and great-grandmother of Jack and Claire Sullivan; the dear sister of Joan Calley of GA, Alice Gaudette and husband Henri of ME, MaryAnn Donahue of Stow, MA and the late Ruth Mahoney, Helene Jamieson and Judith Staples. She is further lovingly survived by many nieces and nephews.

In adherence with the Covid-19 restrictions, Funeral Services are private. In lieu of flowers, donations in Peg’s memory may be made to the Greater Boston Food Bank, 70 South Bay Ave., Boston, MA 02118., or to the Rockingham Visiting Nurses Association
