Hi, Cliff.
The first two links, listed under burial information, repeat below, under "Notes" - the first is to a photo of the Runk Family Plot name stone (it just says "Runk") and a list of those buried there. The second is to a photo of John Runk Jr.'s headstone - not as good a photo as appears on the free site, Find A Grave:

Derik Herron was the source for the Ancestry material as well as for the FindAGrave memorial and the original WT entry. You can contact him through the link on FindAGrave, since he isn't active on WT. He might give you permission to use his photos and the biography (a PDF file on Ancestry) he wrote.
You've managed to locate most of the sources elsewhere. The problem with leaving the Ancestry links (even though they're all active) is that they go to a Family Tree, not directly to the source in the Ancestry database. So, if the tree goes away (if the membership lapses, for example, or if an inheritor makes it private), the links will become useless. My suggestion, therefore, is that you go with the FamilySearch documents you found and, where the profile has a tree link to Ancestry, eliminate the link and add a note to the source reference, such as: "Also available online at Ancestry.com - subscription required."
Additional note: All the source and repository codings should be eliminated once the references have been manually matched to the sources, since they have no function on WT.
