I received a number of suggestions on my blog post and I want to share them, since all of them are rational and helpful, including:
* Nanakat offered: "Have you contacted Judy Mayfield, the person credited with creating the Find a Grave information? There's a link on her name, so it might be possible to contact her and find out what she knows. She may even have seen the headstone."
* Rita A. said: "I would go to Chronicaling American Newspapers or other newspaper sources and try both years to get an obituary. I would go with the card over find-a-grave but everybody makes mistakes."
* Susan Park commented: "Even though the probate records aren't on micro film you could still call--on the telephone--the county court and ask them to help you. In some of the less populated Kansas counties you can get great help this way. I once listened to a clerk climb a step ladder to retrieve the box that held the probate file I wanted. She came back and said, "Got it!" just like that."
* Sharon helped: "Pleasant Hill is the city cemetery for Concordia. Here is their website.
"You can search their info using Cemetery P-Z. Both Vaux are listed, but only Mary Ann has a death date. The plot was owned by D J. Smith. You could call the office there and see if there is additional info in their records.'
There are pictures of the Samuel Vaux side of the stone, of Mary A.'s side of the stone (shown on her memorial) and of the front of the stone that says "Father and Mother."
The photo of Samuel's side of the stone has this inscription for his birth and death date:
