Nancy Carol Willis: Hello, my name is Nancy Carol Willis. You can remember my name by picturing fancy Nancy singing a Christmas carol. Actually, I'm not at all fancy. Instead, I live in a wildlife marsh in Delaware where I love to watch and study many of the animals I write about and illustrate. I did not change my last name, Willis, when I married, but my first names were changed when I was about nine months old. My birth name was Carol Ruth and my adopted name is Nancy Carol. Nancy Carol Willis.
