As Normalhuman did state, it's more likely the people who work on the show have made spelling errors, due to time pressure or other causes. These minor things could be overlooked and surrounded with speculation, an instance being thus. Yes, tributes could have alternate spellings, but it is rare that such spellings are deliberate. The Watterson family is not deliberately altered.

If they did have an intention, it wouldn't be deliberate for Nicole to have her name misspelled on her credit card, as some people have their names misspelled on theirs (including my mom). Furthermore, there are some instances where the Watterson family has had several debts, as shown in "The End."

As for the speculation that Richard misspelled his yearbook name, there is no such thing as applications to enter your name in your school yearbook.

Finally, a "Waterson" article tracking all the errors the people caused would not really be necessary. All of the errors made are shown and explained in the Animation Errors/Gallery.

Hope this clears up at least some stuff.
