Good Morning Gary,
I checked findagrave for the cemetery, and while it is listed at: http://www.findagrave.com/cgi-bin/fg.cgi?page=gsr&GScid=...
John W. has not been memorialized there. I suggest, that you do so and request a photo. that might (?) give some clues. The only Sanders memorialized there is Talley, Kitty Nellie Mae Sanders. So you might make memorials to any Sanders you know of there also. There is another Sanders Cemetery in Skyline with two Procters listed, but no Sanders. I notied there are Procters at the Kyles location also.
Just for info, I have found some of our relatives at SANDERS (MILL CREEK) CEMETERY in Skyline (different from the other), and have requested the memorials be transfered to me, but the current owner is recalcitrant and I have a request to by pass him in to FAG. That takes months, so I wait.
