I don't recall seeing a single Facundus in Grant or Winn Parish. But looking at the cemetery records from that area, there is a SARAH A. WEBB (born 1867, wife of Hile Dake) buried in the Winnfield Cemetery. You can see the tombstone on Findagrave....http://www.findagrave.com/cgi-bin/fg.cgi?page=gr&GSln=da...
Perhaps this is the Sarah that you saw, definately not your Sarah.
Have you checked to see if the Live Oak Methodist Church has records of the burials in that cemetery. First burials there were prior to Sarah's death. Perhaps she is in the unmarked grave on row 13 next to her husband J.D. Walton Facundus.http://files.usgwarchives.net/la/livingston/cemeteries/liveo...
