All that can presently (November 2023) be gleaned about Carl Kellard
from sheet music covers and by Internet searching is that he was presumably an American pianist/composer, married to Edith Clifford
, who has been credited as pianist on 2 works recorded in 1927.
He is also the one-off composer of Love Lies
(1928) published by Lawrence Wright Music Co.
, London W.C., England which features his wife.
Surfers are welcome to contribute information about this pianist/composer.
