All that can presently (July 2023) be gleaned about The La-Cey Sisters
from sheet music covers and by Internet searching is that they were presumably American actress/singers who have been featured on just one work namely When the Maple Leaves Were Falling
(1912) music by Tell Taylor
, and published by Tell Taylor
, Chicago, Illinois, USA
Their portrait on the left is taken from that same work.
Surfers are welcome to contribute any further information about these performers.
