Name and getting acception

So I talked to my husband about our daughters name. And it's been decided. We are going with my name choice. So officially her name is......Nani Rianah Jada Johnson. Yes she is named after Lilo's older sister from the cartoon. I thought it'd be cute. Also how do I get my family to accept it? My grandmother keeps calling my baby Ezra and I don't wanna keep telling her that I refuse to name her Ezra. Not that I don't wanna use a Bible name but why do I have to? It's not fair when I just don't want to.
