John M. Rosko
September 23, 1946 - July 28, 2026
John M. Rosko, age 79, of Middletown, DE, passed away on Tuesday, July 28, 2026.
Born in the Bronx, NY on September 23, 1946, he was a son of the late Dewey “Joe” and Elizabeth “Betty” (Hornacek) Rosko. John proudly served in the United States Army where he worked on Hawk missiles, and spent a year in beautiful Germany. After the Army, he went into a long career as a computer programmer and systems analyst. John exceled in his career due to his outstanding logic and detailed performance.
From a young age, with the help of his dad, John loved and understood the mechanics of cars. He loved Fords, especially Mustangs, as well as attending all kinds of car shows throughout many states. John belonged to the First State Mustang and Ford Club in Delaware for many years. He also volunteered on their executive board in the role of newsletter editor and publisher for the last 10 years. John was very proud of his accomplishments and the club.
John loved being on a crew in sailing races on Greenwood Lake, located on the border of New York and New Jersey. He would be a part of the crew in a Lighting boat on the weekends and enjoyed many rides in a speed boat with his wife on the lake. John also loved to fly small planes and achieved his pilot’s license, working his way up to an instructor rating. He and his dad would fly to many airports together, and John and his wife enjoyed many airshows locally and out of state.
His life was about the love of family and friends. John enjoyed time with all his family as he danced the polka or just laughed for hours. He will always be remembered as a good man, and a loving father, grandfather and husband. John was a wonderful friend to many and will be missed terribly.
John is survived by his loving wife of 43 years, Debra J. “Debby” (Lewis) Rosko; daughters, Laura West (Bud) and Sharon Proia (Mark); stepdaughter, Stacy Jost (Bill); and grandchildren, Ryan, Jessica, Nicole, Ethan, Emma, Katherine, and Olivia.

John was a gem of a human being. Gracious and kind, always willing to crack a joke and smile. He loved his family and friends which was always evident and shown. I will personally miss our trivia battles and his voice calling me “shortie.” Or “shortstack.”
My condolences to his beautiful family, his amazing wife Debby and his children and grandchildren. All the people who met him were lucky enough to be in his presence.
The world was a better place with John Rosko in it, now heaven is even better.
Until the next ride 💛

Debby & Family. I am so sorry for John’s passing. I have lived in Florida, full time, since 2017. I have stayed a club member enjoying John’s club news letter. He was a fantastic organizer putting the letter together for all of us to read. Hopefully he will see all the kind thoughts people have left in his name. God bless.

John will be missed greatly but he will never be forgotten. Some people are a jack of all trades and master of none but not John he was skilled and diligent and mastered each task he undertook. His mechanical abilities were second to none. Not only could he maintain his beloved Mustang but he could take it all apart and rebuild it better than before. His programming skills were outstanding. John was a great friend and mentor. But what i enjoyed most was seeing him interact with his family. They celebrated so many milestones together. During each one they turned moments into memories with all the love they shared. A man who immersed himself into everything and everyone he cared about has left an amazing legacy for his children, grandchildren and wife Debby.
