Hello Don, I found your message last night and was so startled I'm still absorbing it all. What a treasure you found! I do appreciate you so much and I hope you don't mind me reposting the information at Franklin Co., IN. As you probably noticed there was nothing other than birthdate of the son Ziba (from the Cozad Genealogy) so this is really enlightenment for us.
Did you happen to notice that the sister Anne Hathaway died only about three years later than Ziba and she was ten years older than the physican? Interesting!
I'm sure both the CASTERLINE and COZAD families thank you! Now, wonder where Ithiel CASTERLINE b. 21 Jul 1806 went?
