John Stanley Marshall III, 84, passed away on Thursday, July 24, 2025 at his home in Bradenton, Florida.  He was born on October 26, 1940, in Washington, D.C., to John Stanley Marshall Jr. and Lorna Mae (Broadwater) Marshall.  After attending Washington Lee High School in Arlington, Va. he enlisted in the U.S. Air Force.  Upon discharge he began a successful career in telecommunications, commencing in Virginia before transferring to Florida, where he retired.
