Thank you for your reply with such great info! I just want to make sure that I understand: Jacob and Elizabeth Ricketts Duvall had two separate sons, John Miles Duvall and Jonathan Duvall??? I have been erroneously combining these 2 into only one son!
The reason for my query is to identify the parents of William Manson Duvall. We think he is the "Manson Duvall" in the William Ricketts household that you wrote about in your reply. Did you include his name in your message because you believe him to be a son of this John Miles Duvall? If so, do you have any info on him or his siblings? And their move to IL about 1851 - 1860?
