Guy Marshall Hayslett, a devoted husband, father, grandfather, brother, uncle, and friend, passed away peacefully on October 17, 2026, at the age of 83. Born on January 9, 1943, in Martinsburg, West Virginia, Guy was the cherished son of the late Guy Myrvin and Mildred Virginia Brown Hayslett. Guy shared a loving marriage with his wife, Sandra Kay Eaton Hayslett, for over 57 years. Their journey together began when they met at Vitro Corporation in Silver Spring, MD. They wed on February 22, 1969, and their union was a testament to enduring love and partnership. Guy was the proud father to Kevin Marshall (Caroline Osborne), and Laura Ann (Mike Davis). He was also a devoted grandfather to Ryan, Gracie, Nathan, Hayley, Sydney, Jordyn, Julianne, Michael and Grand Dogs Willie, Baxter, Adele, and Lucy. Before settling into his long and fulfilling career in Montgomery County, Guy served his country with honor in the United States Navy during the Vietnam War. He served on the CVA-43 USS Coral Sea Air Craft Carrier as a aviation electrician on the F3 and F4 Phantom Fighter Squadrons. Guy found his professional calling as an engineer for nuclear submarines, a role he maintained with the same company throughout his adult life. He served as principle safety analyst on nuclear weapons system such as the TRIDENT II strategic weapon system and other missile safety systems for the US Navy. His commitment and expertise were respected and admired by his colleagues and he was often called upon as a subject matter expert even after his retirement. He was a life-long active member of the Vietnam Veterans of America, the American Legion, and the Veterans of Foreign Wars. He served as treasurer of the VVA Chapter 641 for many years and was honored to be a part of the Wall Washing Team that went monthly to wash the Vietnam Veterans Memorial in Washington, DC. A man of deep faith, Guy was an integral part of the Viers Mill Baptist Church community, where he served as a member, teacher, usher, Sunday School director, finance committee member, deacon, and deacon emeritus. His presence was a guiding light, offering wisdom and support to those around him. Guy's love for the outdoors was evident in his passion for fishing. He never missed an opportunity to cast a line in a lake, river, stream, or local farm pond. His close friends referred to him as "Spanky", a nickname he acquired in the Navy. He was a lifelong fan of the Baltimore Orioles and the Washington Redskins/Commanders, an avid reader of the newspaper, a crossword puzzle expert, and loved to eat Maryland crabs in the summertime. He also enjoyed duckpin bowling and playing softball with his work friends, creating cherished memories and lifelong friendships. He is survived by his beloved wife Sandra, his children, grandchildren, and his sister Paula Jean Askey (Roger), and a large extended family of nieces, nephews, and cousins. He was preceded in death by his parents and his infant brother, Russell Brown Hayslett. The family will receive friends for a viewing at 10:30 AM followed by a celebration of Guy's life at 11:30 AM on Saturday, October 24, 2026, at Viers Mill Baptist Church, located at 12221 Veirs Mill Rd, Silver Spring, MD. In lieu of flowers, the family kindly requests that donations be made to Viers Mill Baptist Church in memory of his love for missions or the Vietnam Veterans of America, Chapter 641 in memory of Guy's dedication to his fellow servicemen and women.
