Thank you. There is a photo on findagrave.com of Elisha and Phoebe's joint stone. Are you a member of findagrave? If not, sign up (costs nothing) and do a search for Elisha Stone in the US, Maine, Somerset County and a link should come up.
You say your Hiltons were in Moose River. I assume you mean up near Jackman. There is a little cemetery north of Jackman close to the Canadian border that is a Hilton cemetery. I don't know if these are offspring of William Hilton, son of Ebenezer or grandson of Ebenezer. He lived in Solon. I suppose some of them could have moved further north. Are these names familiar in your search?
HIltons anyone? Which line are you following? I see you are researching the Dresden area, so maybe you are after one of Ebenezer and mary Lord Hilton's children? Please let me know. We may be able to help each other out.
