His name is Carlisle.
Although some believe his human name was Stregoni Benifici, that alias is merely a myth he created. The Stregoni Benefici, is, by definition, a vampire that does not kill humans, and has a pure soul and does good in society. Carlisle's human name was never mentioned, nor was his last name.
When Carlisle became a vampire he discovered that it was better to be vegetarian vampires. When Carlisle was changed and he found out what he was he hid in an abandoned hay silo and then while he was wandering in the woods he saw a herd of deer and lost control but Carlisle then realised he could live on animal blood. so the Cullens have been vegetarians since Carlisle was changed.
Carlisle's middle name is never mentioned. The kind of vampire he is is called Stregoni Benefico, which is a good kind of Vampire that fights against "evil" Vampires.
