Good ideas, but a greatbwall. There are at least four 'red herring' answers which make up pairs of answers which can be directly swapped, meaning there are at least four valid solutions. Ariel and Beatrice can be swapped (Ariel is definitely a princess and Beatrice is a redhead). Change Beatrice to Eugenie eliminate that problem. Also, in the old Disney cartoon , Tweedledum & Tweedledee are redheads, which means Tweedledee could swap from the twins group, with Fred Weasley in the redheads group - in the book Lewis Carroll doesn't mention their hair colour, or them being twins.
