Jove

Jove is the English name of Jupiter, Roman "King of the Gods," the god of sky and thunder, equivalent to the Greek god Zeus. He was an incredibly important figure for the Romans during the Republican and Imperial eras before Christianity. Romans would swear "by Jove" as some modern day people swear "to God." His symbol was the eagle, featured on many Roman military emblems. (Side note: Aquilina means "eagle.") The Roman government looked to him as a witness of oaths which they would be held accountable for. Those who protected the emperor, his personal guard, were known as Jovians. He has been important in many aspects, even being a recurring part of C.S. Lewis's work, and Lewis loved to use the word jovial, a word that means joyful, of which the name Jove is strongly connected.

I like that this name feels familiar, fitting right in with one syllable popular names like Jack, Jace, James, John or Joel. It is also connected to Jovan and Jovani in sound, though those three names are forms of John. In 2011 there were only 9 baby boys named Jove. If you're looking for a rare mythological gem, I say claim this one.
