The names "Jessica" and "Lorraine" don't appear in the anagram section because any anagrammed names taken from those would have to be either pretty fanciful spellings of known names, or merely made-up names.
"Jassice" is one anagram of "Jessica" but, as you can see, it's not exactly a "known" name. :)
Why don't you try your hand at coming up with some anagram names for Jessica and Lorraine?
