Their names were Cora, Dawson and Callan Clancy and they lived on Summer Street in Duxbury.

On Saturday the community joined together to build a playground in their memory: the new Clancy Family Playground at 495 Tremont St.

“This playground will be more than just a place to play — it will be a lasting tribute, filled with love, laughter and light. A space where families come together, children play freely, and the spirit of these three cherished souls live on in every joyful sound,” an invitation to help build the playground stated. “Together, let’s create a place where their memory continues to inspire and uplift our community.”

The children’s father Patrick Clancy got to do the ribbon-cutting honors. He had moved away from Duxbury following the Jan. 24, 2023 tragedy that shattered his world.

That evening, prosecutors say, their mother Lindsay Clancy, who was a labor and delivery nurse at Massachusetts General Hospital, strangled each of them with exercise bands in the basement.

Lindsay Clancy is charged with murder for the deaths of each of them. Five-year-old Cora and three-year-old Dawson were pronounced dead that night while their younger brother died at 8 months old three days later.

Much of the coverage has been focused on the mother, who attempted suicide that same night, and her defense attorney’s claims that she was suffering from post-partum psychosis, was misdiagnosed and over-medicated and remains “extremely emotional” and “suicidal.” She has participated in the relatively few court hearings from hospital beds as her case slowly moves through the court system. Her next pretrial conference is scheduled for Dec. 1 with a trial date set for Jan. 5, 2026.

But as the legal system slowly churns along in her case, whole generations of Duxbury children will know the names of Cora, Dawson and Callan from now on.
