Oh, this is rich. Our favorite family tale, told frequently over Sunday dinners, was that we were secretly descended from the Stuarts. In which case, I'm willing to share title to Balmoral Castle, though the upkeep and taxes should continue to be paid by its present occupants, the Queen and her family.
Personally, I prefer the family tale that we are descended from Hansel and Gretel. Though a trifle more speculative, establishing that "fact" through DNA would be one for the books. Grimm, truly grimm.
I jest. But you knew that.
