Diane F. (Cocco) Flanagan

Of Walpole, passed away unexpectedly Saturday March 20th, 2021 at Boston Medical Center at the age of 74.

Born on October 20, 1946 in Waltham; daughter of the late Dominic F. Cocco and Lucy M. (Sullo) Cocco.

Diane was raised in Waltham and had lived in Nashua, New Hampshire for 15 years prior to moving back to Massachusetts, residing in Norwood and Walpole for the past 3 years. Diane spent the last 20 years worth of winters at her home in Boynton Beach, Florida.

A graduate of Waltham High School; Diane had been employed with the Federal Government Defense Department as a Management Analyst for the majority of her career.

Diane enjoyed going to both the Norwood and Walpole Senior Centers; spending time with family, listening to music, shopping and taking scenic rides with her close and dear friend Ralph.

Diane joins her beloved husband, the late James F. Flanagan, her brother-in-law, the late Dominic Quintiliani of Norwood, her dearly departed sisters, Donna (Cocco) Sutton of Nashua, NH and Lucille (Cocco) Fortin of Waltham.

Diane is survived by her devoted & loving family, especially her sister Carol Quintiliani of Norwood; her dear aunt Linda (Sullo) Rodriguez of Watertown; and several generations of beloved nieces and nephews. She cherished the grandmotherly role she held with her great nieces & nephew, Audrey Quagliozzi of Lowell, Eleanor Fortin-Stokes of Quincy, and Charles Fortin of Nashua, NH. She will be greatly missed as well by her dearest friend Ralph Guange Jr. of Saugus.
Dear sister of the late Donna Sutton and Lucille Fortin; and her brother-in-law the late Domenic Quintiliani.

Dear Diane, may you rest in Heavenly peace. You have been the most dear and cherished friend to us three sisters for 46 years. You were a truly genuine person with a heart of gold, between bad times and good times always keeping the laughter. You gave me the best advice ever and I have endless wonderful memories of you. My heartfelt thoughts and prayers go out to your family, whom I know you loved to no end, and hope they may find peace now that you are with Lucy, Lucille, Donna, and Jimmy. Carol Chapman
