Helen R. Dahill, 99, passed away Aug. 17, quietly at her home in Harbor Beach, Mattapoisett after a long and full life. Born in Dorchester, she was the eldest child of Edward and Margaret (Shortell) Dahill. One of five children, Helen grew up in Taunton and graduated from Taunton High School and Framingham State College. She then embarked on a career as an educator at Taunton High School, where she taught home economics for 30 years. For many of those years, she also supervised the cafeteria and developed a school lunch program that was widely copied throughout the state.

She is survived by her sisters Marybeth Dahill, of Mattapoisett; Patricia DuBois, of West Wareham; and Sister Margaret Imelda Dahill, of Puebla, Mexico; along with numerous nieces, nephews, and their children. She was preceded in death by her brothers Edward Dahill, of Provincetown, and Arthur Dahill, of South Yarmouth.

Helen loved to laugh, travel, cook, and spoil her 11 nieces and nephews and their offspring, which she did at every opportunity. Helen was a woman of strong opinions, which she was not loathe to share with those within earshot. She made the world a better place by being in it. She will be fondly remembered, and missed.

Her Funeral Mass will be celebrated at 10 a.m. at St. Anthony’s Church in Mattapoisett, on Aug. 20. Internment will be at a private service in Taunton.
