According to the Goodspeed History, the last name was Kunz (Swiss-German Ashkenazi, with a 14th Century COA). Please, where did you find the name Kuntzy? Would really like to know the origin and any documentation Mr. Dunn might have.
Thanks Kevin. I clearly have Kunz and Kuntz, Swiss.
it is a BAD idea posting email addresses in PUBLIC discussions, because it will be picked up by SPAMMERS. So you might want to delete your comment.
