Sorry, I don't have any information on Elizabeth Treadway in Illinois. I only have information on Charles Treadway and his wife. I know there is an old book on the Treadway in my family. I saw it when I was younger. I believe my Treadway line started in or around Tenn., thought am not for sure. All info I have is sketchy. Will keep in touch if I get good informtion, or documentation.
