All that can presently (July 2022) be gleaned about Cecelia Weston
from sheet music covers and by Internet searching is that she was presumably an American actress/singer who has been featured on 2 works published in 1907.
Her portrait on the left is taken from Bye Bye Dearie
(1907) music by Harry von Tilzer
, words by Andrew B. Sterling and published by Harry von Tilzer Music Pub. Co.
, New York, USA.
