Help with boy name!

DuckySnyder

We have a girl name all picked out but we are having so much trouble finding a boy name we both agree on... We can come up with first names but never a middle name to go with it.
What names, that are not too common but not INSANE, would you suggest for these names?:

Callen
Parker
Coltyn

We want something that isn't too extreme but something that when they go to school there won't be 5 other kids in their class with the same name. O.o

I've been bouncing back and forth between Colton and Coltyn,  some people like it, some don't, I'm still trying to decide if I like the original spelling or with a 'y'.

Thank you for your suggestions

We have a Callen Francis. Also thought about Callen Matthew.

Parker Harrison
Parker Jude
Callan Joshua
Colton Josiah

I agree w/ pp, please spell it Colton!

I couldn't use the name Matthew, it goes pretty well with Colton but my brothers name is Matthew and he gave his son that as a MN.
Jude is very cute, idk about it with Parker though...
