It's been a long time since you posted this but I hope this gets to you.
My GG Grandmother was Maria Shidler Richards wife of Joseph both in marked graves Beallsville Cemetery. I was researching there son Harry Hudson Richards my G Grandfather and in the last hour came across a web site that has 2 Rev War Vets buried on Harry's Old Farm. Harry passed in 1963 at 92 yrs.
I don't know if he farm is still in the family but one of the vets buried in a "Private Cemetery" is John Shidler.
Your John Shidler (sp) moved to West Bethleham Township near Marianna??? That is exactly where Harry Richards Farm is located. Is this Grave your John possibly. Here is the web site detailing what I have said. firstname.lastname@example.org
