OK, your father must be Don SHELDAHL, yes?
If you will let me have your e-mail address I will send you what info I have. I can take your line back to Simon KLUCKHOHN, who came over from Germany probably before the Civil War. You are different Kluckhohns than mine, at least as far as we know right now, but we come from the same little area in Germany, not far from Hamelin of the Pied Piper (they call it "Hameln.")
My e-mail address is
rhkluckhohn@home.comRegards,
Bob
