Born in Brighton, Jane was the cherished daughter of the late Henry F. McCarthy, Jr. and Mary E. (Ford) McCarthy. Raised in Watertown, she graduated from Rosary Academy and in 1964, answering a call to faith and service, Jane entered the Dominican Sisters of Saint Catherine of Kentucky, where she served for six years.

Jane devoted her professional life to Catholic and public education. She taught at the Coolidge, Hosmer, and Cunniff Elementary Schools in Watertown, earning a reputation for compassion, discipline, and an unwavering belief in every child’s potential. She later served as principal of the Cunniff Elementary School and Watertown Middle School. After her years in Watertown, she became Head of School at Mother Caroline Academy in Dorchester, where she championed faith-based education and opportunity for young women. Across decades of leadership, she mentored faculty, supported families, and shaped generations of students.

In her retirement, Jane continued her mission internationally, helping to establish the Maranyundo Girls School in Rwanda, traveling there more than 25 times, where she worked to ensure a strong and sustainable educational foundation. She built lasting relationships within the community and considered this work among the most meaningful of her life.

Over the years, Jane opened her home and heart to foster children, providing them with love, stability, and a lifelong family.

For three decades, through the Paulist Center in Boston, Jane prepared and served meals to people experiencing homelessness as part of the Wednesday Night Supper Club.

Jane’s lifelong commitment to service was honored with the Isaac Hecker Award for Social Justice, recognizing her unwavering dedication to advancing dignity, expanding opportunity, and living her faith through compassionate action.

Above all, Jane’s greatest joy was her family. She was the beloved mother of James O’Connor, Jr., Chief of the Stoneham Police Department, and his wife Danielle of Watertown; Elizabeth O’Connor and her husband Andrew Boroff of Ipswich; and Erin Macomber and her husband Gregg of Watertown. She was a devoted and adoring “Mimi” to James and Katelyn O’Connor; Sarah and Luke Boroff; and Emma, Morgan, and Julia Macomber. They were the light of her life, and she cherished every moment spent loving, guiding, and celebrating them.

Jane was the former wife and lifelong friend of James O’Connor, Sr. She was the dear sister of Kathleen Duffy, Pauline McCarthy, Henry McCarthy III, Richard McCarthy, and Daniel McCarthy. She is also survived by many loving nieces, nephews, cousins, in-laws, and friends.

For the past five years, Jane courageously battled ALS, meeting its challenges with grace, resilience, and a spirit that inspired everyone around her.

She will be remembered for her deep faith, tireless dedication to education, and boundless love for her family. Her legacy lives on in the countless lives she touched as a teacher, mother, grandmother, sister, and friend.
