Middle name woes!! Help!

Christy

My hubby and I are expecting twin boys in December. We have decided on the names Will and Finn. We are pretty set on William Oliver. It just kinda goes together. Finn will be short for griffin. Any thoughts on a middle name? We are just kinda stuck! It's hard to come up with 2 names you just love. We wanted something sentimental, but just can't come up with anything at all. So I'm welcoming all name suggestions.

The name Griffin was a suggestion from another poster as a longer name for Finn so maybe I'll get some help with this too!

Thanks!!!
