In 1941, the family returned to Oklahoma for a visit with relatives; it was at a family picnic during that visit that he met Willadean Gloden, the sister of one of his cousin's husband. They were marrried March 7, 1942, and their son, Larry, was born in December of that year.  They were married for 74 years, until Willadean's passing away last year.

Following the war, they dry-land farmed in Oklahoma, where their second son, Stephen was born in 1949. In 1953, they relocated to Nampa, Idaho, where they continued farming for a while.  Devon subsequently entered the retail workforce , where he made a number of lasting friendships, until his retirement in 1970. Some of Devon's achievements included becoming a Deacon in the Church, becoming a private pilot, owning a champion cutting horse, and sinking a hole-in-one.
