Hiller/Von Huller
My dad was John Horton Sloss, and his father was Alexander Coffee Sloss II and his mother was Anna Maria Hiller. I don't know much about her family other than her parents Karl and Marie Hiller farmed in Wisconson after immegrating from Austria. I think it is possible that their original name was von Huller, and family tradition said that Karl left Austria to avoid the military service expected of him.
