Monk Estill's Words Preserved between 1936-1938

Two things strike me about this account. One, that the capture and preservation of this account was the result of the nation's investment in the Federal Writers' Project of the Works Progress Administration, a 'make-work' project in times like our own ... of dire financial outlook among workers. Secondly, this is purported to be a slave's account (Monk himself was long dead, I assume): I was skeptical about any of the Estills taking care of Monk's financial needs. Other accounts report this was the doing of James Estill's brother Samuel, who subsequently moved to Tennessee. James Estill's oldest heir (Wallace Estill, 1771-1860) was only ten years old. How likely is it that he cared for Monk "in comfort for the rest of his life?"
