Peacefully, passed away on Thursday, February 18, 2021. Jean was born on November 16, 1926 in Lawrenceville. She married her loving husband, Joseph on August 23, 1947. She was the mother of Richard (Marylou) Heiser, Janine (Dennis) Kopko and the late Christine (surviving husband Ray) Pilarski and Donald J. (surviving wife Debbie) Heiser; grandmother of Angela (Dave) Sciullo, Adrienne (Brent) Biagi, Denise Heiser, Jeffrey Pilarski, Kristan Heiser and Jeannie (Bob) Byrnes; great-grandmother of Julianna, Nicholas, Christine, Ava, Joseph and Finnegan. She was preceded in death by her brothers and sisters. She was the aunt of Barbara Starr and also survived by additional nieces and nephews. Jean was a homemaker and life-long member of St. Jude Parish (formerly St. Raphael Parish) in Morningside. Jean loved cats, and there was always one in her home, most recently her beloved Casey. All she met, recall her sweetness and her love for and pride in her children, grandchildren and great-grandchildren. Jean loved her family above all else. She was never more happy then when everyone was all together for Sunday dinners, holidays, birthdays and visits. Jean was admired for her strength and grace. Her family was able to spend time with her during her final days on earth. Her life has come full circle as she joins God, Jesus and her family in heaven-her beloved husband Joseph, her daughter Chrissy and her son Donnie. Family and friends are welcomed at the WALTER J.
