HELP! Boy Name Help Needed

Ive had the most difficult time trying to pick out a boy name that I honestly like and can stick to...

I like uncommon names but nothing compleatly uncommon. My eldests name is Grayson.

And this little boy will be

SOMETHING Clarence...

Or

Something Tatum Clarence...

Really need help. Id like it if it would kind of sound good with Grayson but its not required. Nothing with a C, Z, X, S, Y, J, D, U, or I (I know thats weird) (C names are ok if I can use a K instead)

(OCD Family) 🤷

Any help is so appreciated

I'm due next month
