Quentin

You don't have to give birth to four other boys before you choose this name, traditionally reserved for the fifth son. Director Quentin Tarantino ushered it into the mainstream a decade ago, and it comes with the splashy nickname Q. Old-fashioned but also offbeat, Quentin could grow up to be a comic-book illustrator or a senator.
