The final list:
Diana
Grace
Dd is expected to arrive the 16 of July and we have no clue which name to choose. We have no problems with either name. DH prefers Grace and is constantly referring to dd as Gracie already. I love the name as well, but I can't let Diana go, it's underused and beautiful, and I've always liked it. However, I do think Grace sounds better with ds(s) names, Ezra and Sasha. Surname is one syllable and begins with an F. When asked, E preferred Grace but S preferred Diana.
Middle names are family names and she will either be Grace Aurelia or Diana Mirielle.
