All that can presently (May 2025) be gleaned about Ede Mae from sheet music covers and by Internet searching is that she was a Californian soprano who has been featured on just 2 works published between 1918 and 1919.
The Music Trade Review (Issue: 1919 Vol. 69 N. 11) describes her as the prima donna of the Million Dollar Dolls Co., and billed as "The Sunkist Prima Donna" or "The California Nightingale."
She studied under Louis Croxon, of the Metropolitan Opera House.
Her portrait on the left is taken from I Cannot Believe I Lost You (1919.) words & music by Max Prival and published by Jos. W. Stern & Co., New York, USA.
