No one wants to give it a shot?
Well, it looks to me like Karoline wants to pair trendy first names with more conservative middles, so here are a few combinations I would suggest:
Aiden David
Cole William
Gavin Daniel
Hunter Nathaniel
Jace Charles
Landon James
Parker Vincent
Tristan Joseph
Wyatt Andrew
Xander Anthony
More than 4, I know... we gotta give her choices, though, right?
