Jean was predeceased by her parents, her infant son Victor William Baird, and a very special aunt, Irene Smolder, who was like a second mother to her in many ways. She is survived by sister Audrey Maycheck and many nieces and nephews. Good-natured and vivacious, Jean made the most of life. She treasured many dear friends with whom she delighted in sharing travel experiences and other adventures. A gifted singer, she loved participating in choirs and ensembles throughout her life. She was a devoted aunt, and her family knew she would bring fun and laughter to any occasion. Jean retired from Pittsburgh Port Authority Transit, following a long career in customer service and logistics. Prior to that she served as an administrative assistant for a number of Pittsburgh companies. There will be no viewing due to the pandemic.
