Where were you when you realized Elizabeth Olsen was the younger sister of Mary-Kate and Ashley Olsen?
As noted OTCU (Olsen Twins Cinematic Universe) historians, we’ve known that fact for quite some time. But for some WandaVision fans, discovering that connection between the trio was mindblowing.

Did you know Kate Middleton is actually part of the same family tree as two of Hollywood’s most famous sister duos? Or that an iconic sitcom star is Jason Sudeikis‘ uncle? And how about that Lenny Kravitz gets a mini-family reunion every time he stops by Today?
Of course, we included some surprising sibling pairings too, which include Jonah Hill and a Game of Thrones star.
