All that can presently (December 2022) be gleaned about Brownie Carroll
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 Come Josephine in My Flying Machine
(1910) music by Fred Fisher
, words by Alfred Bryan and published by Maurice Shapiro Music Publisher
, New York, USA
Her portrait on the left is taken from that same work.
