I'm not saying she doesn't have Ackerman blood flowing through her, or that she's not an Ackerman at all. But if it did say clan instead of family,  then it's likely she's not as closely related to Levi and Kenny as everyone thinks. Not to mention, Kenny's own wording in the flashback made it seem like they weren't that closely related. He certainly didn't seem to put that much effort into finding them as he did for Kuchel.
