Claude is super cute and classy. It would be adorable on a kid and very handsome on an adult. Would you be saying it "klode" or like "clawed"?
I'd use one of my family's French names for the middle:
Claude EtienneClaude CharlesClaude PierreClaude Antoine
I could also see some thing like:
Claude VictorClaude HugoClaude JuliusClaude Albert Claude Yves (this strikes me as very haute couture)
Claude LaurentClaude AlainClaude EloiClaude EustacheClaude GaspardClaude HerveClaude LazareClaude Philippe /
Claude Philip
I think
Claude and
Peter are very dashing together.
