What are some names that surprised you when you looked at their popularity charts. Some of my examples:
Wren -I had no idea why this was never in the top 1000
Abigail -This didn't appear in the top 1000 until the 50's. I thought for sure it would have been there long before that
Hayden and
Kyler -I had no idea that people were actually using this name semi-commonly in the 80's
