Name for Addi's twin brother

I’m writing a story about a set of twins, a boy, and a girl.
I already know I want to name the girl [name_f]Addi[/name_f], but I’m having trouble with the boy.
I don’t want anything too matchy, and not anything longer than two syllables. I’m open to more syllables only if it can be shortened by a nickname.
I’ve been considering names like Toph ([name_m]Christopher[/name_m]) and [name_m]Quade[/name_m]. Something different without sounding too strange. The story is set in a pseudo medieval world. Any suggestions are welcome!
