Jack met his sweetheart, Jean Terry of Moore, Idaho, at a church dance and never had eyes for anyone else. Jack and Jean introduced Jean's brother Cecil to Jack's sister, Donna and the four of them began a unique relationship that lasted for the rest of their lives.

In 1951, Jack served his country in the Korean War. He spent time in Japan and Korea before being honorably released in January 1953. After writing every day while he was away, Jack married Jean and Cecil married Donna in a double wedding in the Idaho Falls LDS temple, 13 January 1953. They were married for 64 years.
