I do not insist on the surname Ornstein or Ohrenstein. In the documentation of the graves of Třebíč, Ornstein is mentioned, but I do not exclude that the surname Ohrenstein could have been mentioned somewhere. It doesn't make sense to constantly change something. I suggest the Ornstein version, if anyone has a document that mentions Ohrenstein, it may be the Ohrnstein(Ohrenstein) version
