Camden, Carter, Sawyer, and Cooper!
Garret, Lennox, Maddox, and Monroe. I like Wesley and Wilder, but they are both pretty similar to Kenton's middle name, Wiley.
Holden, August, Elliot, and Porter! Thanks for helping.
Declan and Sawyer. Well, I like a lot of them, but they aren't six letters. That's okay though, I love the inspiration!
