All that can presently (July 2023) be gleaned about The Lovenberg Sisters
from sheet music covers and by Internet searching is that they were presumably American actress/singers who have been featured on the just one work given below.
Their portrait on the left, together with The Neary Bros
., is taken from When the Parson Hands the Wedding Band From Me to Mandy Lee
(1917) music by Arthur Lange
, words by Bernie Grossman and published by Joe Morris Music Company
, New York, USA.
Surfers are welcome to contribute any further information about these performers.
