The Baroness, nee Ploetz, divorced Endell and lived with Felix Paul Greve (later Frederick Philip Grove) in Palermo, Italy, Wollerau, Switzerland, Paris-Plage/Étaples, France, and Berlin from 1903 to late July 1909 when Greve disappeared from Germany with a faked suicide to start a new life in North America. She followed him to Pittsburgh in 1910 and the couple farmed near Sparta, Kentucky, until Greve left her there a year later. She became a model and artist in Greenwich Village, New York where she had married Leopold von Freytag-Loringhoven in November 1913. This marriage made her a bigamist, since she and Greve were never divorced. She was involved in avant-garde ventures with New York Dada artists like Man Ray and Marcel Duchamp, until she returned to Berlin in 1923. In 1925, she moved to Paris where she died in December 1927.
