A little bit, but nothing that would be considered a game changer. I've been researching Parsons and his brigade/division for over 25 years. I recently came across quite a few primary resources that are in private hands. I have a two-part mini biography on Parsons that is published in Confederate Generals in the Trans-Mississippi Vols. 1 & 2 (Univ. Tennessee Press.) Those are a prelude to a book-length treatment of Parsons and his men that I am working on.
