[1][a] It is unknown where or how she had acquired her education,[b] vocal training or acting skills, but at the age of nineteen, Byron made her West End debut at the Globe Theatre (Newcastle Street) in the chorus of Les Mousquetaires in 1880.
[4] For the next 5 months, she honed her skills playing minor opéra bouffe roles at The Globe opposite Henry Bracy[c] with no billing, appearing in La Belle Normande in January 1881.
[d] She returned with the production to the Strand Theatre in August 1881, before starting rehearsals in a new English adaptation of Edmond Audran's opéra comique, La mascotte by Robert Reece and H. B. Farnie.
"[20][e] Life in the "manor house" was short lived, as it emerged that Adolphus Ferguson was experiencing financial difficulties,[22] and in February 1884, he was declared bankrupt.
[27] In January 1886, still in Glasgow, Byron performed duets with Emily Soldene,[28] but by April, she had returned to London preparing for a new opéra bouffe, creating the role of Jacquette in the Lily of Leoville opposite Henry Bracy and Violet Melnotte.
[21] At the end of the summer of 1886, Byron was offered the part of Zoe in Commodore and Sir Walter Raleigh in Kenilworth to tour in America alongside her friend Violet Cameron.
[44][i] By the end of the year, she was able to return to the stage with her old company at The Avenue, playing the part of Earl Darnley in Robert Brough's revival of the burlesque The Field of the Cloth of Gold, which ran until February 1890.
[53][54][55][56] In reality, Byron's professional days in the theatre had ceased a few years earlier in 1890 concluding a decade on stage, although she did make rare recital or guest appearances as Mrs Harold Winterbottom.
