Las Vegas, Nevada - John Doyle Ryan, age 88, of Las Vegas, Nevada, passed away on January 15, 2026, at Las Ventanas, the senior living community where he lived. Doyle was born on August 1, 1937, in Grinnell, Iowa, and was the youngest of four children born to Terese Elizabeth (Kilcoin) Ryan and Thomas Philip Ryan.

After graduating from Brooklyn High School in 1955, Doyle attended Iowa State College in Ames. He graduated with a B.S. in Farm Operation in 1959.

Doyle and Martha Jean Horan met at a freshman mixer at St. Thomas Aquinas Catholic Church in Ames. They dated all through college and were married on June 27, 1959, at St. Patrick Catholic Church in Ottumwa, Iowa. Doyle ran a cow-calf operation and raised corn and soybeans on his farm north of Brooklyn for 40 years, before retiring to Las Vegas.

Doyle was well liked and personable, and blessed with a singularly dry sense of humor. He will be greatly missed by all who knew him.

Doyle was preceded in death by his parents, his wife Martha, his brother Thomas W. (Niki) Ryan, and his sister Acquin Ryan.
