My brother was born on December 10th! He'll be 16 this year!
As for my opinion on the names, I really do like Audrey. But Marie is not a favorite name of mine simply because it is a bit overused sometimes. What about the name Audrey Claire? Two very pretty, not overly popular, solid names. The name Sophie reminds me of a snobby poodle or something, sorry! Good luck in the choosing!
