NEED Opinions Please

So I've had this name in my head for a little girl in my head since I was in eighth grade and I still love it just as much. Abigail Elizabeth, and calling her Ellie. I know going by the middle name isn't ideal, but I don't think Elizabeth Abigail has the same ring to it. My boyfriend's mother had a daughter she had that she lost with the name Elizabeth and I'm scared she won't approve it 😔 any other name suggestions that I'll fall in love with?
