Who is Morton koopa Jr named after

Most likely he is named after Bowser's father, or Mortons's Grandfather. But it could be almost anyone. Bowser does not like his father, because his father faked his own death and came back pretending to be the fifth spirit of the great spirit guardians. And since the Nintendo magazine "Nintendo Power" said that when they asked who Morton was named after, he pelted them with bob-ombs, it is probably because he doesn't like to talk about his father.
