We still have no proof whether relatives have or doesn't have similar Zanpakuto. Muramasa is not-canon therefore you cannot compare it with Senbonzakura. If we are to receive a proof, we must wait if Ginrei's or Sojun's Zanpakuto wiLL be revealed.

and if you're referring to my "Ichigo stealing Isshin's bankai" it's sarcasm for the guy who thinks Yhwach is Ichigo's father.
