Which one sounds better?

OK so I'm starting a new story on Wattpad and I need to know which sounds better, some teacher names, and I need to know some last names for 2 names.

Which sounds better:

Chelsea Offerman
Jeanette Offerman or
Brittany Offerman

Also I need last names for the names Summer, Cameron, and Brady.

Also some names for teachers here are the type's of teachers:

Math
Science
Drama
Language Arts
Spanish
History
Art
Chemistry
Music
P.E.

Jeanette Offeman sounds best (in my option), and it could be Summer Chillcun, Cameron Willsenberg and Brady Jones???

Chelsea Offerman sounds best (in my opinion). For the other names...Summer Winston, Cameron Jones, and Brady Wilson?

Ehh...that's all I got. I'm not the best at names...
