Little is known of Blake's life. Promotional materials from Paramount Records indicate he was born blind and give his birthplace as Jacksonville, Florida, and it seems that he lived there during various periods. He seems to have had relatives in Patterson, Georgia. Some authors have written that in one recording he slipped into a Geechee or Gullah dialect, suggesting a connection with the Sea Islands. Blind Willie McTell indicated that Blake's real name was Arthur Phelps, but later research has shown this is unlikely to be correct.
