Retired Master Sergeant Fred Harding Libby III passed away unexpectedly at his home in Porter, Maine on March 23, 2024. Fred was born May 30, 1951 in Portland, Maine to Fred H. Libby Jr and Mildred (Harmon) Libby. He enlisted in the US Air Force after graduating from Bonny Eagle High School in 1969 and served over 20 years as an Air Traffic Controller and Aircraft Jet Engine Mechanic, with military tours to Seymour Johnson AFB NC, Thailand, Keesler AFB MS, Pease AFB NH, Zweibrucken AB Germany, and Cannon AFB NM. A few years following retirement from the service, he relocated back to his home state of Maine where he worked as a mechanic and truck driver for a number of years. Although sometimes referred to as a grumpy old…man, he truly loved all his family and friends. He was known for his sense of humor and passion for muscle cars, to include an occasional burnout (or two). Fred was a wonderful husband and proud father. He is survived by his wife of 49 years, Sheryl (Sherry Stackhouse), Porter, ME; three sons, Fred H. Libby IV and wife Chantel, and David M. Libby, both of Niceville, FL, and Matthew J. Libby and wife Andrea, of Porter, ME; grandchildren, Aleigha Yarbrough of Houston TX, Shayla Libby and Fred Libby V of Niceville FL, Paige Guptill of Cornish ME, Elyse Guptill of Parsonsfield ME, Brooklyn Libby of Porter ME; and great-granddaughter, Magnolia Mae Ducharme. Also surviving are sisters Sharon Jackson and husband Billy of Buxton ME and Carol Abbott, brother Robert Libby and wife Charlotte of Standish ME. As well as many nieces, nephews, in-laws and friends who also loved him dearly. He was preceded in death by his parents, Mildred and Fred Libby Jr; grandparents Ida and John Harmon, Mable and Fred Libby Sr; in-laws David Stackhouse, Eileen (Bunny Horne), and James Ackroyd. Services will be held Monday, April 1, 2024 at Dolby, Blais and Segee Funeral Home, 434 River Road, Windham, ME. There will be an hour of visitation at 1:00pm, with service following at 2:00pm.
