Whats in a name?

just wondering if anyone actually knows the meaning of their own names. My names is Natasha, and have no idea where this originated. My twins names are Manawa, which means "my heart" in Maori and the other is Pania, which was a mythical sea goddess in Maori legend. If anyone has any interesting names or stories to go with them, would love to hear all about it, have fun searching!
