I have searched all the names of Koy and have no result in finding any relation to me. My great great grandparents came from, I think, Germany in the late 1800s. Their names were August and Anna Koy. They settled in Jefferson County, Illinois. I know some of my relatives moved to Chicago but from there I am lost. They had something like 12 children but only brought 6 or 8 of them to the US. My great grandfather was Joesph Frances Koy and I know he had a brother named Tony. Any help would be appreciated. Thanks
