All that can presently (July 2023) be gleaned about
The Jewell Sisters from sheet music covers and by Internet searching is that they were presumably American actress/singers who have been featured on 2 works published between 1912 and 1915.
Their portrait on the left is taken from
Take a Little Tip From Father (1912) music by
Irving Berlin, co-author
Ted Snyder, and published by
Ted Snyder Music Co., New York, USA.
Surfers are welcome to contribute any further information about these performers.
