Well, I mean, if we go with your idea of "presumed dead," then while telling the story, Yang could've off-hand mentioned that she and Ruby almost ended up like their cousin.

I dunno. Either way, I think if she had a cousin or a secret half-sister, they would've searched for a way to insert at least one mention/hint, like they did with Winter.
