His third marriage was to 13-year-old Myra Gale Brown, his first cousin once removed, on December 12, 1957. His divorce from Jane Mitchum was not finalized before the ceremony took place, so he remarried Brown on June 4, 1958. In 1970, Brown filed for divorce on the grounds of adultery and abuse, charging that she had been "subject to every type of physical and mental abuse imaginable."
