Since Im sure someone will call me on this:
"New Hampshire: A female between the age of 13 and 17 years and a male between the age of 14 and 17 years can be married only with the permission of their parent (guardian) and a waiver"

And theres Mississippi where "Marriage licenses cannot be issued to males under 17, or females under 15 years of age. If the clerk receives a signed authorization from the parents, this minimum age requirement can be waived"
