Sharon Marie St. Onge

Sharon Marie St.Onge,74, of Nashua, passed away peacefully on November 3, 2025, surrounded by her loving family. She was born on December 1, 1950, in Lowell, Massachusetts, to Frederick and Florette (Bellemore) Swiderski of Chelmsford.

Sharon was a woman of quiet strength and unwavering integrity—the kind of person who always did the right thing, even when no one was watching. She lived her life guided by compassion and kindness, touching the hearts of everyone who knew her.

A devoted animal lover, Sharon found joy in the simple things: birdwatching, gardening, and attending church fairs. She shared 56 years of marriage with her beloved husband, Edward St.Onge, and was a proud and loving mother to Scott and his wife, Jennifer St.Onge, and Tracey (St.Onge) Pelletier.

Sharon’s legacy lives on in her cherished grandchildren, Dylan St.Onge and his wife, Carolyn, and Jillian St.Onge. She will also be dearly missed by her sisters-in-law Linda St.Onge and her partner Wally, Nancy Monkiewicz and her husband, Ray, Eleanor Hedlund, Norma Lucontoni and her husband, Jimmy, Susan Dulac and her partner, Bob, and by her brother-in-law Steven St.Onge and his wife, Christina. Her loyal dog Delilah will also deeply miss her comforting presence.

She was preceded in death by her parents Frederick and Florette Swiderski, in-laws Norman and Ruth St.Onge,  brother-in-law Richard St.Onge, her beloved pets Kelsey and Ozzi.

A private celebration of life will be held at a later date.  In lieu of flowers, the family kindly asks that donations be made in Sharon’s name to Granite State Dog Recovery NH https://www.granitestatedogrecovery.com/ or Wings of Rescue https://www.wingsofrescue.org/
