Michael Daniel Byrne

Michael Daniel Byrne, age 76, of Elkton, passed away peacefully on January 13, 2026 at his home surrounded by his family. He was affectionately known to many as "Big Mike," "Rich Mike," or simply "Mike". He lived life to the fullest and spent his final years in Elkton, Florida, surrounded by love, debate and laughter.

Mike was born to Harold and Pearl Byrne on May 11, 1949, in Milwaukee, Wisconsin. He was a graduate of Dominican Jesuit High School with the Class of 1967, Mike pursued further education in engineering at the University of Wisconsin at Milwaukee, but his passion for adventure cut his college life short. He built and rafted down the Mississippi River, built his first of three sailboats and traveled via the Mississippi across the gulf down the coast of Mexico. In-between building boats and traveling he honed his skills as a carpenter and construction that truly defined his career. An accomplished building contractor, Mike, had an unstoppable energy for his craft, specializing in creating custom homes and encouraged owners to participate in the project.

Mike's eccentric personality was as untamed as his wanderlust. A skilled carpenter and sailor, he constructed his third and final sailboat Fishhead, and sailed south to explore the waterways and warmer areas of the country. Landing in St. Augustine, he met the love of his life, Cindy Wilson, and they united in marriage on November 3, 2001. Together, they built a loving home in Elkton, where they enjoyed life, laughter, and countless cherished memories.

Mike leaves behind his beloved wife, Cynthia Wilson and her two adult children, Anna Scott, husband Chris of Ponte Vedra; and Jeffrey Wilson, wife Mercy of Jacksonville; a sister, Patty Byrne of Wisconsin; his grandchildren Morgan, Jack & Eli and many nieces and nephews. He was preceded in death by: Harold Byrne, Pearl Byrne, and his sisters Judy Wolf, Marianne Baldus, Jeannie Doxtator.

He will be remembered for his spirited love of life, his unstoppable energy, and the amazing ability to figure anything out he set his mind to. Mike was always ready to engage in friendly banter infused with his signature Irish wit. He will be deeply missed.

A celebration of Mike held at his home, the date yet to be determined.

St. Johns Family Funeral Home is in charge of arrangements.
