Where was Alice Cullen origanally from?

she can't remember anything, because she was sent to an insan insalium, because of her visions. James (The one who tracked Bella) thought she smelled good. So he was going to kill her (she was still human at the time.) But an old vampire in the insulium made her a vampire to keep her form getting killed. James couldn't kill Alice now. . .so he destroyed the old vampire in vengence. hope it helps!
