name ideas

i need a name for one of my characters. Here's a brief description,

-white male
-comes from a wealthy family.
-goes to a catholic school
-lowkey mean
-has green hair
-really messy

I would prefer a name that seems really prim and proper but can be shortened to a nickname. Some names I'm considering are Edmund and Nicholas. Thanks for any suggestions.

Thanks for these suggestions! I'll take them for consideration.

Casper
Benjamin
John
Steven/Stephen
Cedric
