I have had a response to my other source. I belong to a Guffey Family website and another member of that site is a descendant of Andrews brother, Hardy Smith Guffee. He is going to do some digging at home this weekend and will post something Monday.
His name is Eddie Guffee. You can e-mail him directly at firstname.lastname@example.org. Tell him you are the lady that Verlyn was talking about. That way he can e-mail you directly and I won't be in the middle of it. Apparently, Eddie does not have internet service at home.
By the way, would you be interested in joining the Guffey Family website? There is no charge to you as Joe Guffey and another member started the site and pay for it. If you can contact Joe, ask him about joining.
