Hello, From what Ft Parker has on Elder John Parker, Nathaniel Parker and Ann Clayton are his parents. Also from other historical sources that are well documented this is the case.
I am updating Elder John Parker's descendants for Fort Parker and so if you are related, I would very much like to talk with you about your history. It seems that the Fort's descendant chart has not been updated in several years. I believe way over 15 years. So if you are related to Elder John Parker PLEASE contact me directly at firstname.lastname@example.org
