David Theodore Cousineau

On November 15, 2025, David Theodore Cousineau passed away after a long battle with dementia. David was born on May 23, 1936, in Holyoke, Massachusetts, to Blanche and Theodore Cousineau. He graduated from Holyoke High School and the General Electric Apprenticeship program. David married Bonnie Rouleau in 1957 and settled in Richmond, Massachusetts where they raised their three children before moving to York, Maine and later Naples, Florida.

Always one to take care of others, David took early retirement from GE at 56 so that the staff he had so diligently trained would remain employed longer at the Somersworth, NH plant before their jobs were transitioned to the Carolinas. Not one to stay idle, David continued to keep busy giving historical carriage tours in Portsmouth NH and enjoyed following his passions of music, history, skeet shooting and spending time with his grandchildren.

David, Dad, Grandpa, Bompa or Grandpa Maine, will be forever remembered for his attention to detail and his sharp sense of humor. Always the prankster he loved to tell elaborate stories about his childhood that usually included a trick he played on one his siblings or school buddies. His shirt pocket was always prepped with 3x5 index cards, his "junior woodchuck" planner and a Swiss army knife. He was very much the engineer in his attention to detail, yet embraced the principled traditions as his Gin & Tonics were always served on a silver tray.

Forever a learner, he taught himself to play the 5-string banjo, standup bass, make his own root beer, took dance lessons, read everything he could about the civil war and could recite the Gettysburg address from memory. He loved sharing this wealth of knowledge with the next generation, whether it be giving demonstrations at the schools at which his wife Bonnie taught or at the historical societies at which he volunteered.

David was predeceased by his wife Bonnie early this year and his brother Carl. He is survived by his brother Theodore Cousineau (Cosette), Sister Nancy Jolivet (Arnie), Brother-in-law John Rouleau, sister-in-law Sharon Babb (Joe), Children Terrill Ploss (Kevin), Stephen Cousineu (Cheryl) and Geoffrey Cousinea (Shannon), Grandchildren Jared Ploss (Sharon), Ashlin Ploss (Christine), Gabrielle Rancourt (Dana), Danielle Hartung ( Joe), Mandy Dinan (Jesse), Andrew Cousineau (Claire), Elizabeth St Hilaire ( Jarrett) and 10 great-grandchildren. David was truly adored by his family and will be greatly missed.

A Celebration of Life will be held for both Bonnie and David in March. The family urges donations to be made to Avow Hospice in Naples Florida. Katie Jarvis has been David's nurse for the past year; she is an amazing caregiver who cared deeply for him and our family. https://avowcares.org/
