Hogwart's Descendant

What if Voldemort isn't the only descendant of Salazar Slytherin? What if a girl named Jazmin was the descendant of all the fonders? You may be wondering why i didn't say her last name. I didn't forget, there is a reason. Nobody knows her last name. When she was one her parents got killed the same way Harry Potter's parent did. In fact Voldemort visit her house first. The only problem was Voldemort couldn't find Jazmin. She was under her own invisibility cloak. That's all you need to know for now.
