What is the most common name you've heard of?

The most common for me is Sara/Sarah. There are 4 Sarah's and 1 Sara in my first hour. There is also another Sarah in my fourth hour, and I'm friends with her and the one Sara from my first hour. Also, there is a seventh grader on my bus named Sara and there's at least one other girl in my school that I know of named Sera, though it's a different spelling. I am sure that there are a lot más Sarah's in my school. Oh, and did I mention my name was Sarah?
