hmmmm...you have my curiosity peaked now. I have a distant older cousin who was married to a Frantz (I think that's the spelling, not absolutely sure). They divorced, he has since died, but she is in her 80's and lives nearby in Dufur, Oregon. I will contact her soon with your question, and see if she can be any help. It may not be any relation at all, but you never know!
