Marcia L. (Jones) McCarthy, of Melrose, MA, formerly of Jamison, PA, passed away peacefully on April 3, 2026, at the age of 88, following a beautiful stay at the Care Dimensions Hospice House in Lincoln, MA.

Marcia was born to Edward and Florence Jones on May 11, 1937. She was the fourth and youngest daughter in the family, and twin sister to Robert. Raised in West Roxbury, MA, Marcia attended the Richard Olney Elementary School and Christian High School in Cambridge, MA. In 1958 she married Dennis R. (“Bob”) McCarthy, and their three children, Robbie, Liane, and Doug, were born in North Chelmsford, where the family lived for 15 years. They moved to Indianapolis, IN, following Bob’s career, and then to Lancaster, PA, eventually settling in Jamison for 35 years.

From an early age, Marcia’s life was marked by her spirit of leadership and service. As her classmates at Christian High School declared in their yearbook, The Lantern: “Nothing we write about Marcia could do her justice. She’s just about the backbone of our class.” In high school her activities ranged from Science Club Secretary to Basketball Scorekeeper to Class Vice President to yearbook editor.

She moved from her parents’ home at 19 Ruskin Street to marriage and to motherhood, which she considered her most important and successful role. But she embraced all of her titles— sister, daughter, aunt, cousin, mother-in-law, grandmother, and friend—with equal dedication. Throughout her life, she maintained close contact with all her siblings and their families. Weekend visits from Helen and the Von Schmidts, pool days in Chelmsford, trips to Disney and Barbara’s house in Deltona, summers on Cape Cod. Marcia hosted and cooked for whoever made the trip for Christmas or Thanksgiving, always making it special. The record one year in Pennsylvania was 21 people for Thanksgiving. Nieces and nephews could count on her signature treats: unlimited Fruit Loops for breakfast and her legendary “company potatoes” for dinner. Nothing made her happier than making chocolate chip cookies for her grandchildren in college.

Always a peacemaker in her family, she practiced kindness and generosity in the wider world. She was an early social activist in her own way, supporting bussing in South Boston in the 1970s through her church and participating in a program to bring inner-city children from Lowell to the suburbs of Chelmsford. (Robbie, Liane, and Doug learned how to say, “Hot bread an buttah, come an’ get your suppah!”) While living in Indiana, she sponsored foreign officers from nearby Ft Benjamin Harrison. They came to her home for gatherings and holidays to get to know the real American life. Officers from Brazil, Philippines, Rwanda, South Yemen, Turkey, and Egypt all became regular guests. She had a gift for making everyone feel welcome and at home.

Marcia personified the saying about enjoying the little things in life, and she made sure the people around her enjoyed them too. She was excellent company—a warm, quiet presence who could surprise you with her quick wit, infectious laugh, and keen competitive edge when it came to Scrabble. An early riser, she loved spending mornings with her sister Helen on the deck in Cape Cod. She read widely—books, magazines, the novels of Zane Grey, the local paper cover to cover every morning. She exercised her own creative talents as a prolific crafter, quilter, and gardener, and could frequently be found weeding one of her many gardens or trying out a new container arrangement. She was unparalleled in the arena of holiday decorating: half a dozen Christmas trees, each with a theme—garden, angels, birds, Santas, vintage. Her Easter bunnies seemed to multiply each year. Luckily, her organizational skills were epic. Whether it was in her role as president of the Warrington Garden Club or PTA, administrator of the neighborhood Santa visit schedules, or family archivist maintaining her files and labeling her vast quantity of bins in the basement, she knew exactly where everything was and what needed to be done. She never missed sending a birthday card.

She was diagnosed with cancer in 2012, and it came back in 2017, when she lost her ability to drive and to walk without a walker. Similar to her brother, who fought Guillain-Barre Syndrome for more than a decade, she persevered. She often said she didn’t worry about the cancer. She rarely complained, to the amazement of all those around her, and still made dinner for her husband every night until they both moved to Melrose in 2024. Many a doctor predicted her demise, only to be surprised by her strength and resilience. No doubt she was helped by her faith. After she became housebound, she continued to come up with ways to help others—sewing crafts for the church fair, helping to make cards for special occasions and writing little poems to include inside them.

Marcia was predeceased by her siblings: Barbara Willey, Eleanor Weston, Helen von Schmidt, and Robert Jones. She is survived by her husband of 68 years, Dennis R. McCarthy, her children Robert McCarthy (partner Deborah Holmes), Liane McCarthy, Douglas McCarthy (wife Laurie Coville) and grandsons Jacob and Willem McCarthy, and grandchildren Frank and Katie Holmes, as well as many, many nieces and nephews.

Relatives and friends will gather to honor Marcia’s life at a funeral service at the Melrose Highlands Congregational Church, 355 Franklin Street, Melrose, MA on April 11, 2026 at 11:00am. Interment will be private and held at a later date.
