I know that your message was from a year ago, so I'm hoping your still interested. My family knows very little about our history on the Bortz side. My grandfather, Clayton Bortz, lived in Portage, wi and married Irma Mae Blystone. I don't know if he was born in wisconsin or not but I have also heard that one of his brothers live in wisconsin, but I don't know where. I don't even know if this is connected to your family but seeing how I don't have much information, I thought I'd give it a shot.
