Princess Hilda married in Berg Castle on 29 October 1930 Adolf 10te Fürst zu Schwarzenberg (Frauenberg, 18 August 1890 - Bordighera, 27 February 1950). The couple shared a passion for agriculture, wildlife and botany and spent much of their time at their Stará Obora hunting lodge near Hluboká. They acquired Mpala Farm in Laikipia, Kenya in 1933. Apart from bringing modern farming methods to the estate, Princess Hilda's husband built a hydroelectric powerstation there (some of the machinery was imported from his native Hluboká) and made exceptional improvements to his workers' living conditions. He inherited the family estates after his father's death in 1938. They did not have children.
