Is Amelia a popular name?

So I really like the name Amelia for our baby girl (after Amelia Earhart). My husband and I are big nerds, we both work at NASA, so this name has a solid meaning for us. But we are afraid the name has become too popular lately, ranking as #15 in the US last year...does anyone know if this name is very popular for kids right now? We don't want her to go to school with a bunch of kids with the same name! 
Another name we kinda like is Sally, after Sally Ride the first female American astronaut, but we think that might be too plain and simple...
