A "long shot" for a brick wall may be the Denmar TB Sanitarium in West Virginia. Folks came there from all over and many folks died there.

See Deaths at the West Virginia Colored Tuberculosis Sanitarium at Denmar from West Virginia History, pp 76-87 which can be found at

Many of the d.c.'s that I have recently been posting are folks from elsewhere who died at Denmar.
