Baby girls name... HELP!?

My husband and I are expecting, we know what we will name it if it is a boy. For a girl he likes Molly, I am notw so fond of it. I like Emma (too popular), Anna and Lily. I have also though of using a family name. My mom's name is Donna his mom's name is Susan. If I could combine the two, I don't know. The middle name will be Colleen. I 'm really like clic names. I had thought of Susanna (combo of Susan and Donna).
