However, if Meghan Markle and Prince Harry have a baby girl, Her Majesty will most likely change the law so that little Baby Sussex can have a dukedom.
As it stands, only a male can hold the title.
Dukedoms are the highest ranking title which can be given.
For now, dukedoms can be given only to a son and male-line grandsons of the British monarch.
Dukedoms can also be inherited, but only by a male descendant.
This could mean that if the Duke and Duchess of Sussex have a girl, their title could die out.
Finger's corssed Her Majesty makes an exception!
