What do Tilda Swinton, Christopher Plummer, and King Princess have in common? They're all celebrities with famous ancestors. All of the celebs on this list aren't distantly related to notable historical figures - these individuals can actually claim direct descent from at least one historically significant ancestor. Celebrity ancestors include royals, politicians, and artists - in other words, accomplished people who are known outside the context of their famous descendant. Whether they appeared on a genealogy show - like PBS's Finding Your Roots, African American Lives, or the BBC's Who Do You Think You Are? - or grew up hearing about their famous ancestors, these actors, musicians, and personalities are appreciative of their storied backgrounds.
