All that can presently (June 2022) be gleaned about Caleb-Wilson O'Connor
from sheet music covers and by Internet searching is that he published 3 works between 1905 and 1906.
Here, I would like to express my thanks to a descendent of the forenamed for drawing my attention to the composer himself as well as to George Atwater
and Stanleigh P. Friedman
with whom he was associated.
Surfers are welcome to contribute any further information about this composer.
