Theresa Gallagher

Theresa “Terri” Gallagher, of Philadelphia, PA passed away on her 97th birthday, Saturday, June 6, 2026. 

She was born in Glenside, PA in 1929, the daughter of the late Francis Delzingaro and the late Mary (Buccini) Delzingaro. 

Terri spent her entire life in and around Philadelphia, from 29th & Allegheny in the city to Plymouth Meeting, Andalusia, State in Schuylkill, and later Bakers Bay in Northeast Philadelphia. No matter where she lived, she had a gift for making people smile and feel welcome. She made friends everywhere she went and was loved by many. 

Terri was a devoted parishioner of St. Katherine of Siena Roman Catholic Church and an active and cherished member of the St. Katherine’s Primrose Senior Club. She loved bowling, dancing and reading mystery novels. She challenged herself daily with Wordle and was a passionate Philadelphia sports fan. Above all else, she prioritized family and togetherness, and was fiercely devoted to those she loved. She never missed a family wedding, travelling to RI, FL and Canada in recent years and NC last month, dancing up a storm every time.

Her bright spirit, resilience, and loyalty will be fondly remembered by all who knew her. 

For 67 years, Terri was married to the late John J. Gallagher, a member of the First Troop Philadelphia City Cavalry. Along with her husband, she was preceded in death by two daughters, Diane Gallagher Solomon and Baby Teresa Gallagher; son, John J. Gallagher, Jr.; brother, Anthony Delzingaro; and grandson, Douglas Solomon. 

She is survived by her beloved son, Rick Gallagher and his wife Michelle Desrosiers; daughter-in-law, Marlene Gallagher; son-in-law, Charles Solomon; and sister, Al (Addie) Egan, from whom Terri was inseparable. She is also survived by six grandchildren whom she loved dearly, Justin, Joy, Rick, Sean, Grace and Leah; nine great-grandchildren, Ian, Zoe, Chloe, Harper, Jack, Ben, Wyatt, Sylvie and Avery; as well as numerous nieces and nephews. 

Her Funeral Mass will be held on Monday, June 15, 2026 at 11:00 AM in St. Katherine of Siena RC Church, 9700 Frankford Ave., Philadelphia, PA 19114. Relatives and friends are invited to the viewing on Monday morning from 9:30 AM to 10:45 AM in the Church prior to Mass.
