Another name for Jupiter, king of the Roman gods, this jovial name is eminently ready for modern use. Feminine variations include Jovita and Jovie.

Jovan, the name of the supreme Roman deity, seems more extraterrestrial now -- and it's also firmly attached to a perfume label. Some parents may see it as a variation of Giovanni, the Italian for John. It is in fact the Slavic variation of John and may be an original way to honor an ancestral John.

Avita sounds like a drug name. In fact, it is! (It's an acne medication.) While that may not be enough to stop you, you might want to consider Aviva, Vita, or Evita (which has issues of its own) instead.
