All that can presently (September 2022) be gleaned about The Elinore Sisters
and May, from sheet music covers and by Internet searching is that they were an American vaudeville duo who have been featured on 2 works published between 1903 and 1907.
Their portrait on the left is taken from When My Girl From Tipp'rary Tips Me
(1907) music by Stephen R. Henry
, words by William Cahill and published by Jos. W. Stern & Co.
, New York, USA.
Surfers are welcome to contribute any further information about these performers.
