Darmond married Randolph P. Jennings, who worked in the oil industry, on January 22, 1928. The marriage ceremony was performed in Hollywood by a minister named James H. Lash, and witnessed by Lillian Willat (legal married name of actress Billie Dove) and Robert Fairbanks (possibly Robert Payne Ullman, who was known professionally as Robert Fairbanks, brother of the actor Douglas Elton Thomas Ullman, aka Douglas Fairbanks). The probable venue of the wedding was 7065 Hollywood Boulevard, which was the site of the Hollywood Congregational Church in the 1920s.
