One general suggestion, oe specific one. In general, we shy away from airing dirty laundry in public IF it is about living people. Your post told the whole world about a murder and an elderly fellow in a nursing home who isn't right inth ehead. He deserves his privacy.
A KEY descendant in Tennessee has a PRF entry for Walton. The PRF is the LDS equivalent of the WFT CD's.
I hope this helps. Your next step might be to write for the marriage record; with luck it will mention John's parents.
Another step would be to write or e-mail the people who have John and Ruth. (Send a SASE to the PRF contributors). Ask them what their sources are. Offer to swap what you have - omitting dates on living individuals.
