Here is a link to her obit: http://dlg.galileo.usg.edu/gordonobits/pdfs/gco-lm-00004018.pdf
She is buried in the Nichols plot, which is why I included the picture of the Nichols headstone. There is not a Clara Jones Thomas nearby. Mary Ruth's daughter Betty is still living, as is her husband Bill. Don Gresh and I did a complete survey of Fain Cemetery this year. If you want additional pictures, it is easy for me to get them, because it's just two miles away.
RE: Swamp Creek Cemetery I don't think I replied to this yet but in the late 70's or early 80's when the cemetery book was compiled there was a listing for Lucy Jones 1896-1968. It lists beside her name that the info came from a metal marker such as the funeral homes use and indications are at that time she had no tombstone. There was no information for a William in the book. I am not sure who to contact at Swamp Creek but one of the local funeral homes may be able to tell you and give you a phone number.
RE: Swamp Creek Cemetery I am not sure how to get in touch with the correct persons for the cemetery but I would suggest calling one of the local funeral homes and see if they can give you the name and number of the caretaker for the cemetery. The caretaker should have a list of burials and their locations. I am sure the funeral home has to contact a caretaker whenever they have a new burial to make there. Sorry that I am not any more help.
