An American Wizard at Hogwarts

Nick Negron was a regular guy, until he died and woke up almost fifty years in his past, halfway across the globe from where he had always lived. Oh, and he's a Wizard during the rise of Voldemort, as well as Lord to an otherwise extinct House. Then there's Bellatrix Black, trying to figure out why Nick is so different. Hopefully, Nick can stop the War before it truly begins.
