[2] According to Marguerite Sylva's entry in the 1935 edition of American Women, it was W. S. Gilbert who gave the sisters their stage names.

[6] The young couple had planned to pursue musical theatre careers together in the United States, but in the end, the engagement was broken off.

Sylva remained in the United States where she carved out an increasingly successful career in musical comedy, operetta and vaudeville.

She appeared in the world premiere of The Fortune Teller by Victor Herbert and toured several U.S. cities playing the leading roles in The Princess Chic, Miss Bob White, and The Strollers.

On 1 September 1909, Marguerite Sylva made her American operatic debut as Carmen at the Manhattan Opera House.

She also sang in Europe, including an acclaimed 1912 performance in Carmen at the Berlin Royal Opera with Enrico Caruso as Don José.

On July 8, 1922, three days before the first season of "Symphonies Under the Stars," the Los Angeles Philharmonic, itself only 3 years old, mounted a lavish production of Bizet's opera.

[16] In her later years, Sylva lived in North Hollywood, where she played a series of small character roles in films and taught singing.

She was severely injured in the accident and died the following day at the age of 81 in Behrens Memorial Hospital in Glendale, California.

This list is restricted to her known Broadway performances only: Sylva's early venture into cinema was probably the title role in a 1913 silent film of Carmen shot in Nîmes, France with M. Habay (an actor with the Théâtre Sarah Bernhardt) as Don José.

[20] Her first major role in a Hollywood film came in 1920 when she played Hilda Wilson in The Honey Bee directed by Rupert Julian.
