Middle name help.

We’ve chosen a first name for baby, Léonide (pronounced “LAY-AW-NEED), husband is French hence the French name and now we’re trying to come up with a middle name. The difficulty is that we plan to raise our child gender neutral/not share their sex with anyone until they want to (if you have rude/mean/hurtful comments about our parenting choice, I respectfully ask that you please keep them to yourself), so the middle name needs to be a gender neutral/unisex like Léonide. Open to any suggestions, thank you!
