I was going to suggest you name her Symphony but then she might get a nickname Phony. That wouldn't be good. How about Harmony?
My wife named our first boy Shanachie because she heard it on the radio and liked the sound. As you may know, it is the name of a record label. On further investigation (after naming him) we learned that it means "Tribal Historian" or storyteller in Gaelic.
So good names are all around. Listen for one and you will know it when you hear it. Keep in mind that it needs to work well with your last name. If its Hoar, don't name her IMA.
