Hi, I came across your transcriptions for this cemetery last night. I noticed one error for Joel Graves Scidmore. He died in 1884. You have the death date as: Joel (Graves) Scidmore Nov 13th 1838-Aug 2nd 1934[NYSHS26]
I have a photo of the headstone for reference if you'd like to confirm.
Thanks for all the work you've done posting all this data. Regards, Dyane McIndoe
