Crack Theory Alert: Could the Kurosaki family be one of the unnamed noble houses that has fallen out of that league like the Shiba clan? They could have once been powerful but could have been affected a couple of centuries ago so maybe Aizen is trying to unravel some mystery involving the Kurosaki family. That would be cool. That way, Byakuya wouldn't look down on Ichigo that much for one.
