Lea

The form Lea (without h) if someone has it is derivated from Latin word Leo which means lion so the word Lea is feminine which means "lioness" in Latin. So if someone has name like Lea or Léa it's actually Latin and not Hebrew while Leah with h is Hebrew.

Other than being a variant of Leah, Lea also means "lioness" in Latin.

This name actually means "wild cow" or "someone who tries hard without having success".
