Castor

With the slightly unique meaning of “beaver,” Castor is a boy's name of Greek origin. In classical Greek myth, Castor, along with Pollux, was one of the heavenly twins immortalized in the constellation Gemini. They were considered the patron gods of seafarers, appearing to them in Saint Elmo's fire. In ancient times, many sailors would offer up their prayers in the hope of favorable winds. If you have a connection with the sea or like a name with a good story then Castor is an excellent choice for baby.
