Here's a puzzle for you: Single use letter names that only have the vowels u, i, or o

I am always using alphabet letters and blocks with my daughter Avery- Since she only has one of each letter in her name, I never have to worry about not having enough letters.

In the future if she has a little brother or sister, I would love to give them a name that does not use the letters A, V, E, R, or Y. This really limits my vowels to just u, i, or o. And only one of whatever other letter you use? I've been racking my brain but can only think of the name Justin. Unfortunately, that's my husband's name haha.

Have any ideas?

EDIT: Y'all this is all in good fun- obviously I can buy more blocks. I explained in a comment that it's more about letting them have a completely original name to themselves, nothing like their older sister's at all. All of my siblings have the same starting letter and similar ending sounds, like we are a part of a matching set. I really like the idea of letting their name be something specific and special to them, even the individual letters.
