A first name to go with "Rex"????????????????

So, im not having a baby any time soon (im 16) but i was just wondering what first name would go with Rex. Its wasn't my first choice, but my grandma said that her brothers middle name was Rex, and she has always loved that name, but never had the opportunity to name one of her sons that. Its beginning to grow on me, I just dont know what to pair it with. And im my Grandmas only granddaughter, (she only has two grandkids to begin with). lol im such a good granddaughter! hehe THANKS
