It is with great sadness and heavy hearts that the family of Deron Jay Cowan announce his passing, peacefully into the loving arms of his Savior on June 21, 2026.

Deron (DJ) was born in Plattsburgh, New York on July 13, 1961, to James R. Cowan and Jeanne Ball Cowan. Deron spent his former years in Pomona, NY, graduating from Ramapo High School in 1980. Deron continued his education at Murray State University in Murray, Kentucky, receiving both undergraduate and graduate degrees.

Upon graduation, Deron was commissioned into The United States Army for two years and continued to serve in the National Guard both in New York State and Kentucky, attaining the rank of Captain. Deron’s career of thirty plus years was spent primarily with Zurich N.A., with whom he oversaw construction sites throughout the United States and the world as a risk engineer.

Deron was an avid reader of military history and history in general. He loved traveling throughout the world to visit historic sites, battlegrounds, and architectural marvels, especially bridges. Friends and family from far and near loved to join Deron, and his wife, Rosemary, in their home for one of Deron’s delightful culinary meals. From an early age, he loved to cook, create and to entertain.

Deron and Rosemary lived for several years in Newburgh, Indiana where they were active members of The St. Andrew’s Society, participating in many Highland Games; as well as hosting social events throughout the years.

He leaves behind his beloved wife of thirty-four years, Rosemary Hannan Cowan; two faithful pups; Jake and Beau; a sister, Teresa Lucas; an aunt, Patsy Greer, numerous beloved in-laws, cousins, nieces, and nephews who loved him dearly for his kindness, understanding and sincerity.

Deron leaves behind many dear friends from throughout his life, especially, the Sigma Phi Epsilon fraternity brothers from Murray State, loving friends and neighbors from Newburgh, Indiana and newly acquired friends from Fernandina Beach, Florida.
