Name opinions..??

Ashley • Mommy of an angel, step mommy to two monsters. Baby #2 due March 2016. 😍 All four have my whole heart.
We are having a lot of trouble finding a girl name we like. We had a boy name set in stone but we found out we are having another princess! 👑 anyway.. Our first princess was born at 20 weeks, last December  we named her Emma Anne. I want this baby to share some part of her name with her big sister in Heaven. We are very open about our first daughter being born extremely premature and passing away, so I don't want to hear that this daughter might grow up to feel weirded out or whatever, I've heard that too many times before(not trying to sound rude there). So anyway, I just thought what if we name her Emma Grace, and she will go by Grace/Gracie, but I'm not sure if that is too much? 
Also any other name suggestions would be much appreciated! :)
