Makingdo, re alias: it is NOT a name, it is a word that means a pseudonym or assume name.
The link you provided just means there are some very daft people in the US who don't understand words. Hardly a big surprise. (There are plenty here, too!)
You just confused the name Elias with the word alias. Glad you've decided against it. Because you would have condemned your son to a life of people going 'er, what?' and thinking 'blimey, his parents must have been a bit odd'.
