Stuck on a couple of names for my new book

My main characters are twins with the name [name]Cassidy[/name] and [name]Melody[/name]. They are Life and Death mages. I am trying to come up with a last name for them.

Also, I am stuck on the villain. She is a mage with the powers of kinetic energy. I found [name]Noah[/name] (meaning motion), but I’m not sure it is a good villain name.

Thank you for your help. I am so bad at names.

[name]Wilson[/name]
[name]Stone[/name]
[name]Harvey[/name]
[name]Bevan[/name]
[name]Richards[/name]

[name]Xavier[/name], [name]Sterling[/name], Winterose, [name]Hughes[/name] all sound like good last names. I likethe suggestions of [name]Adams[/name] and [name]Stone[/name].

I looked up “move” and found [name]Noa/name, Zarifa, and [name]Zaza[/name]. [name]Noa[/name] means ‘movement’ in Hebrew. I looked up “energy” and found some interesting names. [name]Chaka[/name], [name]Chakra[/name], Kineta, [name]Moxie[/name] and Urja all have something to do with energy. Kineta is a little cheesey but literally means " full of energy" in Greek.

Good luck!

For the girls, try [name]Moore[/name], and the villian, [name]Stone[/name].
