Suggestions: Other Characters last names

the idea is for those of you who want to suggest a last name for any of this characters, you can do it here! 

I pretty much care that it sounds cool more than anything ... :p
but i don't know all the last names so I'm asking in case I see one i like c: 

Raanea (Raan) : her last name should be from easter-Europe
              (from her dad side)

Vanessa (Ness(y)): American name, could be anything i guess...

Arthur (Rory/Robin in Femme) (the one with the bright blue & pink hair):
I imagine him being from West Europe, maybe he came came to america at a young age (England most likely?) 

PS1: About the previous post... I'm kinda leaning for Sam Summers...
but its true it sounds like a marvel comic character :p ... not really sure if i dislike that--- :p

PS2: I might continue this discussion on discord if I'm still unsure about some names
