I don't know and I don't care. JS was slandered and libeled constantly throughout his life and after his death....and it never ends. And it won't end. That's scriptural.
To take supposed words of people from between 100 nearly 200 years ago and put JS on trial seems suspect in and of itself, let alone unprofessional as a means of investigation.
Besides, nothing anyone digs up is going to supplant the power and credibility of Scripture.
