Haverhill, Massachusetts | Age 63


HAVERHILL - Mary Jo (Dewhurst) Heffernan, 63, lifelong Haverhill resident, passed away peacefully on Saturday, February 24, 2018, surrounded by her loving family. She was the wife and best friend of Jack Heffernan, with whom she shared forty-five years of marriage.

Born in Haverhill on September 21, 1954, she was the daughter of the late Benjamin and Eileen (Halloran) Dewhurst. She attended Haverhill Public Schools, and graduated from Haverhill High School in 1972. Mary Jo recently retired from Holy Family Hospital, where she was a physical therapy aide.

Mary Jo was beautiful, kind and caring. She touched the hearts of many with her warm, genuine bright smile that could light up the room. Mary Jo cherished her four grandchildren, who lovingly referred to her as "Mimmy".

Some of Mary Jo's favorite pastimes were kayaking, bike riding, dancing, campfires, laughing at her husband and especially riding her bright red ATV on the trails surrounding Big Rock Campground in North Stratford, NH with her many friends. Mary Jo greatly enjoyed being with her sisters and brothers playing music and singing along. She loved being with people and just having fun.

In addition to her devoted husband Jack, Mary Jo is survived by her daughters, Keri Greely and husband Jay of Seabrook, NH and Judy Devine and husband Mike of Sandown, NH; four grandchildren Ryan and Trevor Greely, Nora and Molly Devine.

Mary Jo also leaves behind her siblings Benjamin Dewhurst and his wife Karen, Pattie Noonan and her husband Mark, Teresa McCormick and her husband Grady, Judy Lalumiere and her husband Norm, Dan Dewhurst and his partner, Sue Kneeland. She will also be deeply missed by her many nieces, nephews, aunts, uncles, very large extended family as well as all who had the pleasure of knowing her.
