All that can presently (May 2022) be gleaned about Lottie Grady
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 Dat Lovin' Rag
(1907) music by Bernard Adler
, words by Victor H. Smalley
and published by F. B. Haviland Publishing Co. Inc.
, New York, USA. from which her portrait on the left is taken.
It was sung in Smalley
's Burletta, The Merry Widower
Surfers are welcome to contribute any further information about this performer.
