Le Mari de l'Indienne
St. Cyr is best known for her feature role in "The Squaw Man" (1914) by producer/director Cecil B. DeMille and co-director Oscar Apfel, released in 1914. The movie starred Dustin Farnum and Monroe Salisbury. DeMille's first choice had actually been Mona Darkfeather, but she was under contract with the Kalem Company and had to turn down the offer. Her appearance in the film was actually preceded by Jesse Cornplanter's lead in the feature film "Hiawatha", released in 1913, a year before "The Squaw Man". After that last movie St. Cyr had a role with cowboy star Tom Mix in "In the Days of the Thundering Herd" (1914) and another one in "Fighting Bob" (1915). The 1916 version of "Ramona," about Native Americans and Spanish colonists in early California, featured St. Cyr in a small role as Ramona's mother.
