Thanks so much for your reply! Location has been an issue for me up to this point. I have found a 1900 Missouri census were Zachariah and his children are listed. This also lists his birthplace as Missouri. However, I also have found the death certificate for his son Alfred that lists Zachariah's birthplace as Kentucky and other possible death certificate of his son James that lists Arkansas. I feel pretty positive that I'm following the correct line but I cant say for sure as the trials ends at Zachariah.
Also, thanks for the web link!
