Note for future editors. A biography of Marie Hall can be found in the book:

Modern Musicians by J. Cuthbert Hadden (First published by T.N.Foulis in 1913) - (my copy is the September 1918 Foulis reprint)

I'm using my copy but four public domain copies are available at the Internet Archive. Here's two of those:

I have a different image in my book and looking at the quality of the image in this article I'd better scan my book and replace the one here.
