All that can presently (July 2023) be gleaned about
The Hess Sisters from sheet music covers and by Internet searching is that they were presumably American vaudeville singing comediennes and dancers who have been featured on 3 works published between 1911 and 1913.
Their portrait on the left is taken from
My Brown Eyed Baby Boy (1911) music by
Henry I. Marshall, words by Stanley Murphy and published by
Chas. K. Harris, New York, USA.
Surfers are welcome to contribute any further information about these performers.
