Dear Carrie, I don't know if you will get this, it's been so long since your post. I think your grandmother was my aunt Ermie, She was the oldest of nine children, my dad was the fourth child, and first son. His name was Donald Hamilton. Their father's name was Donald William, and their mother's name was Mary Louise. I have some information if you would like to contact me. My dad also had the genetic disease, called Huntington's Disease.
