I really like
Moses. I associate it with the Jewish / Biblical character that led his people out of bondage and with the abolitionist movement in the USA. Apart from the freedom from slavery tie,
Moses also handed down the laws from God that many Jewish people observe, so it has a founding father and religious leader element to it as well.
It is a very powerful name and might be hard to live up to rather like
Solomon or Mandela or any other name that has a strong association or is almost put on a pedestal.
The song "Let My People Go" gives off the feeling of seriousness that I associate with
Moses -
