Resonant and unusual.

Pleasant sound, but too tied to the racetrack.

A Julian derivative, via Spanish conquistadors, that could be a more unusual yet still reasonable substitute for that current favorite.

A Miwok tribe name with a pleasant meaning.

Hurricane is a storm, but it's also an American name, thanks to rising tennis star Hurricane Black -- whose sister's name is Tornado. There's no reason this tempestuous choice can't work for boys too, inasfar as the name can work for any child. As a name, Hurricane is definitely original and attention-getting, but is it a name you'd want to carry around for life?
