I do not. His life was not well documented which give rise to legends filling in tne gaps. Most individuals like to point at the titles of his songs as proof. However, one has to keep in mind that he was known for developing a relationship with anyone he played for as his time as a musician. So, it makes sense that he would add references to things people he played for could relate to. For example, his song “Hellhound on my trial” has a reference to hot foot powder, something that would’ve been common knowledge to people living by the Mississippi delta were he played. It also emphasized the feeling of unrest that would have been relatable at a time when lynching was a very real fear to many people.
While the story goes that he magically mastered the guitar, the story of him taking a couple years break from publicly playing to learn from other blues players and developed his talent. When one steps out of the scene as a mediocre artist and comes back in as very popular local one with lyrics and tunes that can really draw someone in, it makes sense to think there is something else involved. He is not the first musician rumored to make the Faustian deal. But I believe the truth of it is that this is a case of a man taking the time to really mastered what he loved, even at the cost of stepping back from the spot light to give it justice, and becoming a local legend from all his hard work. As for his death, it is believed syphilis had a rule to play in it as he did get around in more ways than just playing his guitar. His songs certainly have sexual references within them and there are records of the women he was involved with, so he had his pleasures in a time where protection was not like it is today.
Ironically the first reference of him selling his soul to the devil was when his first wife’s relatives who viewed her death as his punishment from God when he decided he wanted to play more secular music over gospel
