All that can presently (September 2022) be gleaned about Eily Hélène
from sheet music covers and by Internet searching is that she was presumably an American actress/singer who has been featured on just one work namely Walking Home With Angeline
(1902) music by John E. Rundbach
, words by G. Totten Smith and published by Francis, Day & Hunter
, London W.C.2, England
Her portrait on the left is taken from that same work.
