Jon was born on Jul 25, 1947, in St. Joseph, Missouri, the son of George Maurice Branaum and Ida Lucille (Aeschliman) Branaum, who preceded him in death. He was married on Mar 9, 1985, in Seoul, South Korea, to Yonmi Lee. 

Jon served our nation for over 40 years as a U.S. Air Force servicemember and civilian national intelligence officer. He was a graduate of the University of Maryland and Defense Intelligence College. He proudly supported our country during the Vietnam War and on countless other occasions. Most of all, he was a dedicated family man whose passion for God and country was only surpassed by his love for family and laughter.

Survivors include his wife of 36 years, Yonmi Branaum of the home; three children, Christine Branaum-Brosius (David) of Los Angeles, CA, Isaac Branaum of the home, and Paul Branaum of the home; one sister, Debbie Clark of Katy, TX; one sister-in-law, Beverly Branaum of Columbia, MO, and many nieces, nephews, and cousins. He was preceded in death by one sister, Pamela Lent, and his twin brother, Don Branaum.
