I was googling my grandpa's name and I saw you had posted a message a while back. My name is Karly Coatta and I live in the Madison, WI area. I am 16 and a junior in high school. It's kind've cool to see someone with basically the same name as mine. Were our ancestors spelled Coatta or was it changed somewhere along the line? My dad's family came from Michigan and that's all I know.
