Name for our little miracle baby girl?

My husband and I just began looking for the perfect name for our little girl. We had thrown around names we liked in the beginning of the pregnancy. A few months ago we went to a class in preparation for our wedding and a couple there had a baby named Westervelt, a little boy, who was named after the mother, her maiden name. So my husband decided he would call the baby Day because that's my maiden name. We actually call her Day all the time now, or even like little D or Deedee. LOL. I think it's actually cute now. But so, we are really having trouble finding any names we both really love. We both like Eryn, but it's not like really striking us. We were actually thinking of using Day as her middle name. So her name would be ______ Day Jolie. My husband wants us to name her Angelina as well, lol. I don't think so!! Our naming taste is similar and we both agree on names fairly easy. Our late sons are Killian Alexandru & Israel Jensen. We thought about naming our little girl after them, but we don't want to burden her to have her own personality and not have to carry their names. I mean it's a nice way to remember them, but we won't ever forget them, we don't need to name their little sister after them. Our taste kind of changed when we got pregnant with her and although we still love the names we gave our sons, we are into more feminine names for girls than before. So ultimately, we want a soft, feminine name that goes with "Day Jolie" at the end. We are also open to having two middle names and having a more feminine name as the first middle name and using Day as a second middle name. Thanks so much! ~Ray & Cillian
