Absolutely loving this story. Already finished your Sorcerer's Stone one! I would like to point out, though, that Harry is distantly related to Salazar Slytherin through the Peverell bloodline (funnily enough Voldemort is also a distant cousin of his through that same bloodline) but he isn't related to any of the other founders, contrary to popular belief. Other than that you are amazing with sticking to cannon.
