All that can presently (September 2022) be gleaned about Maude Galbraith from sheet music covers and by Internet searching is that she was presumably an English music hall performer who has been featured on just one work namely Let Me Call You Sweetheart (1910) music by Leo Friedman, words by Beth Slater Whitson and published by Harold Rossiter Music Co., Chicago, Illinois, USA.
Surfers are welcome to contribute any further information about this performer.

The loss of this valuable resource is very sad and a mystery.
