OK, Autumn Kelly is Canadian, but that's in North America, so we're going to add it as our bonus American. Besides Meghan, who just got engaged, and Wallis, who was never really in the British royal family — because King Edward VIII abdicated the throne to marry her — Autumn is the only other North American person to become an official member of the British royal family and therefore linked to the Queen of England.
She married Queen Elizabeth II's grandson Peter Phillips, who is the son of Princess Anne and cousin to Prince William and Prince Harry, in 2008. By marrying him, Autumn gets to hang out with all of your favourite royals for every holiday and birthday, and we're so jealous.
