Mattie Delaney was an obscure blues woman of the 1930s who accompanied herself on guitar, although only two recordings are known (Down the Big Road Blues and Tallahatchie River Blues) she was known to have sang topical songs, rare attributes for a woman performer at that time. Researchers are divided on her birth year (circa 1904-05) and location, with the prevalent identities being either Mattie Doyle, born south of Tchula, Mississippi, or Mattie B. Delaney, born near Goodman, Mississippi.

Researchers are divided on her birth year (circa 1904-05) and location, with the prevalent identities being either Mattie Doyle, born south of Tchula, Mississippi, or Mattie B. Delaney, born near Goodman, Mississippi. Mattie Delaney may have been born Mattie Doyle south of Tchula, Mississippi, but as is often the case with these early now obscure artists, so much has been lost over time and remains little more than number of vague anecdotes. 

Researchers suggest she was Mattie B. Delaney, born near Goodman, Mississippi. Her recording Down the Big Road Blues was a variant of Tommy Johnson's Big Road Blues. On her recording of 'Tallahatchie River Blues music journalists have noted, Mattie was effectively issuing what amounted to a matterof-fact report on 'Tallahatchie River Blues. After recording her two songs she literally disappeared, nothing that can be verified is known of her life beyond 1930.
