Girl name help!

My husband and I came up with a few girls names we really like, back when we first found out we were pregnant, around January. Charlotte was and is our top girls name. 
Now I'm just thinking it might be super popular and commonly used for baby girls this age because of the royal baby / people in Americas fascination with that family...grr lol.  But we still love the name and want to use it if baby's a girl (we are going to be suprised by the gender). 
What do you think? Would you let this sway your decision?
