The original Hans Christian Anderson version of "The Little Mermaid" ends with the mermaid losing her prince and turning into sea foam. In the draft written up for the animated film, Ariel was given a name and she also married the dashing prince.
However, the prince's original full name was Prince Eric La. His last name was shortened from "La Sireneta", which was a wink to Ariel being a mermaid.
Finding the last name "too Hispanic" Disney decided to drop the use of last names altogether.
