"My son was born outside in Hawaii in the middle of a thunder and lightning storm that was so insane that we had an island-wide power outage... We were woken out of our sleep by the thunder, it was so intense, and in Hawaii they call that mana, which is like your essence or your spirit... so we had to name him after his mana." Actress Evangeline Lilly on the genesis of her son Kahekili's name. Kahekili is Hawaiian for thunder.
