Charecter names. Can you help?

I am writing a book and don't know what to name one of my characters. I would really appreciate some help. Any way hear is some info about the character:

Sex: Male
Eye Color: Green
Hair Color: Dirty Blond
Skin Tone: Lightly Tanned
Age:19
Other: He is the brother of my main character Kathrine Wolf. Kathrine is two years younger (17) and looks a lot like him. She also has brown hair, blue eyes and a slight tan even though she hardly ever goes out side. Katherine spends most of her spare time taking care of there sick mother (she has schizophrenia). Kathrine's brother (the guy I need a name for) ran away when he was 17 and no one has seen him since. But he is going to contact Katherine to find out where she is because he wants to come back. He does not know where they are because the family moved. They moved because the mothers doctors said they should get her out of the city (they lived in new york) because they think that the city is starting to make the mother feel crowded and overwhelmed. They also think she has become severely depressed from the brother running away and that moving will help her greatly.

Some other characters:
Aden Wolf: Father
Kalista Wolf: Mother
Katherine Wolf: Main Character
? Wolf: Katherine's Brother
James Smith: Katherine's ex-boyfriend
Ray ?: Katherine's friend
Charles ?: Ray's father and owner of a french cafe/ garbage man
Paul: Garbage man
Milly ?: Katherine's friend

Please post some suggestions for a name. Also if you could think of last names for Ray, Charles, and Milly I would really appreciate it but it is not as important as finding a name for Katherine's brother. I really need to name him and the sooner the better. Thanks:)
