Mario's last name has also been Mario, and in every game he's been in, including the Paper Mario series, his name has been Mario Mario.
Mario is a computerized character used in video games. He therefore wasn't actually "born." The first video game featuring Mario was either Donkey Kong (1981) or Mario Brothers (1983), depending on whether you require him to have been CALLED Mario or not (prior to Mario Brothers, he was known as either "Jumpman" or "Mr. Video.")
