"I got it from my dad."  He admitted with an amused shake of his head.  "I thought his name was Jack and when I went to Hogwarts I just... made it my name too."  He'd be the first to admit it was a funny thing to suddenly decide to do as a kid... if he ever talked about it. 

"Sure, the professors the professors had me down as something different at first but I had 'em all convinced by the end of my first year."  That part he was proud of and the grin that followed showed it.
