I am saying she could be a relative of him or know wear Kusina is. Because she does look a little bit like Kusina to me any ways and so does Karin also.
They might have the same color of hair, but, I don't think that they are related.
Why?
Kushina's eyes are green, right? And she has fair skin. She also looks like Sakura, but Karui doesn't, since she has golden () eyes.
I also know that Kush-chan came from the Land of Whirpool, or something. That explains the 'Uzumaki' part.
I think. I'm not entirely sure. But, you have a point there.
And, Karin, is an orphan, whose parents died in an attack or something.
Edit: Looking back at my post, I sound so unsure. But, this is my opinion anyway, to what you are saying.
