John A. Shemwell, a longtime public servant and community member from Trenton, Michigan, passed away on Wednesday, November 4, 2026, at the age of 60. Born on April 9, 1966, he built a life defined by steady dedication to his career, deep-rooted local ties, and a tight-knit family circle that remained central to his everyday routines.
During his working life, Shemwell dedicated 25 years of service to the City of Trenton prior to his retirement. Beyond his municipal career, he established strong community connections through local organizations. He was an auxiliary member of VFW Post 4230 in Gibraltar, Michigan, and a member of the Loyal Order of Moose 966 in Woodhaven, Michigan, finding lasting fellowship through both groups.
At the center of his personal life was his family. He is survived by his children, Angela Lillian Shemwell and Jesse (Caitlin) Shemwell, as well as his grandchildren, Sofia Francesca Ellis and Jake Shemwell. He also leaves behind his siblings—sisters Diane (John) Bennett, Robbin (Brian) Eritano, and Renel (Brad) Gerwig, alongside brother Robert (Holly) Shemwell—and his faithful dog, Charlie, who shared in the rhythms of his daily life. He was preceded in death by his sister, Denise, and her husband, George Perhase.
