All that can presently (December 2022) be gleaned about Nellie Walker
from sheet music covers and by Internet searching is that she was presumably an American actress/singer who has been featured on just one work namely That Little Sunny Southern Girl of Mine
(1907) music by Chas. L. Johnson
, words by J.E. Jeter and published by The Tolbert R. Ingram Music Co.
, Denver, Colorado, USA
Her portrait on the left is taken from that same work.
