Do Ты have any ideas for last names for the characters who don't have one?

I'm Письмо a fic where characters need last names, and I'm really bad at coming up with them. It would be super helpful if anyone has ideas, especially for the following:

- Maleficent
- Aladdin
- Jafar & жасмин
- Ursula
- Hansel & Gretal
- Jefferson & Grace
- Tamara
- Aurora
- Mulan
- Glinda
- Lancelot
- Guinevere

Any help is appreciated! Thanks :)
