This memorial at Find-A-Grave was "Created by: Douglas King Sr"...
Presumably, he would be associated with the same KING family... Perhaps if we can get Rose Mary Lankford to respond with her research on this matter... There seems to be some discrepancy as to where she is actually buried, or perhaps was re-interred. It seems that documentation has not been found (yet) as to proof of her marriage to Quantrill. There are suggestions that support that Sarah could very well be a wife of Quantrill, yet there doesn't seem to be actual PROOF. Genealogy is a hard row to hoe, but if it is done right with supportive documentation, it cannot be refuted, except through stubborn bull-headedness. ~Don
