Fleming was happy to leave show business, serving as Marx's "valet" and raising their four adopted children. In addition to his widespread interest in playing musical instruments, including his trademark harp, Fleming helped foster her husband's interest in painting; she would make elaborate frames for his paintings, as well as creating her own works of art. The two collected many artworks, which Fleming donated widely after her husband's death. In 1956, they moved to Rancho Mirage, California, with three out of the four other Marx Brothers; Gummo, Zeppo and Groucho building homes nearby.
