There's a Testament CD featuring several of those mentioned above - Johnny Young, Yank Rachell, Carl Martin and Willie Hatcher: 'Mandolin Blues' Testament TCD 6004 1997.

Not mentioned above are Matthew Prater of Nap Hayes and Matthew Prater and Joe Evans & Arthur McClain (The Two Poor Boys) either or both of whom played mandolin on many tracks. As Greg Stephens mentioned above, Coley Jones played mandolin on some Dallas String Band sides. There was a mandolin player with King David's Jug Band and Vol Stevens recorded a great banjo-mandolin piece called 'Vol Stevens Blues' and also played bj-md with the Memphis String Band.

An excellent album that is worth seeking out is Various Artists 'Early Mandolin Classics Vol I' Rounder CD 1050 (1989) put together by Terry Zwigoff, one of Robert Crumb's Cheap Suit Serenaders. Unfortunately, subsequent volumes failed to appear.
