All that can presently (September 2022) be gleaned about
Marie Elsie from sheet music covers and by Internet searching is that she was presumably an English music hall performer who has been featured on just one work namely
Do As the Romans Do (1899) music by
Bennett Scott, words by C G Cotes and published by
Francis, Day & Hunter, London W.C.2, England
From a theatre programme, she is known to have appeared at the Royal Trocadero Music Hall, London, Piccadilly, on November 28th, 1891 along with Miss Sophie May and Mr. T. H. Russell.
