All that can presently (December 2022) be gleaned about Rose Beaumont
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 between 1904 and 1912.
Her portrait on the left is taken from My Girlie Girl
(1904) music by Ted S. Barron
, words by Felix F. Feist and published by Leo Feist
, New York, USA.
