Obituary of Marybeth Chubb

Marybeth “Mb” Chubb (née Costello), 58, of Plymouth, passed away in her home surrounded by loved ones on July 29, 2024.

Marybeth was born in Melrose and grew up in Saugus and Duxbury before settling in Plymouth. A graduate of Middlebury College, she worked at the Massachusetts Department of Environmental Protection for over 30 years.

She loved to learn, have fun, and explore, whether abroad or in her own backyard—summiting Kilimanjaro, sailing the British Virgin and Greek Islands, diving in the Caribbean, Central America, and the Sea of Cortez, touring the National Parks of the Southwest, looking for whales on Stellwagen Bank, and especially spending time on Clark’s Island with the many friends she had there.

Mb was someone who never shied away from a chance to wear a funny hat, care for or comfort someone in need, make you groan with a “good” pun, or deal with a tough physical or mental challenge. Her goodness radiated out—everyone instantly liked her.

Marybeth had a gift for making everyone feel welcome. She hosted countless occasions, making birthdays, family dinners, holidays, backyard parties, and significant events all the more memorable. If you were lucky, she might even write you one of her famous poems.

More than anything, she cherished every moment spent with her husband and partner of 37 years, Lewis “Chip” Chubb, and their daughter, Madigan “Maddi”, whom she loves as high as the sky, and as deep as the ocean.

A wide-ranging crew of people will keep Marybeth present as we try to learn to carry on without her, including her parents, Paul and Joan Costello of Dorchester and Duxbury, who raised her to be the intelligent, strong, independent woman she was. Her siblings, brother Tim Costello and his wife Kate of Marshfield, brother Brian Costello and his wife Karen of Agawam, sister Christine Costello and her husband Tim Sirois of Ipswich, will hold special memories, inside jokes, and nicknames in all of their hearts. Mothers-in-law Carol Chubb and her late husband Timothy Coffey of Plymouth, and Rose Chubb and her late husband Lewis “Bill” Chubb of Duxbury. Sisters-in-law Jeanne Coffey of Bridgewater, Kimberly Murray and her husband Rich of North Andover. Nieces and nephews Brian Lee and his fiancée Reanna, Jackie and her husband Tee, Brennan, Nevan, Amanda, Tabitha, Erin, and Priscilla. Great nephew and great nieces Lennox, Clementine, and Penelope. The Fab Five who shared lifelong love and friendship, the Ladies’ Auxiliary, and many other close friends, dear colleagues, and wonderful neighbors.

Mb found great joy in every aspect of life and frequently created opportunities for others to experience it, too. Her family asks that you do the same. Go out, do something that brings you absolute joy, and share it with those around you.

A wake will be held from 12 p.m. to 4 p.m. on Sunday, August 11th, at Shepherd Funeral Home in Kingston, MA. Friends and family are invited to a celebration of her life (please wear something blue!) from 1 p.m. to 4 p.m. on Saturday, August 17th, at Plymouth Yacht Club, Plymouth, MA.

In lieu of flowers, please consider donations to The Ocean Conservancy or Cranberry Hospice.
