Yes, the stone is very old, dating probably from 1835 when he was buried.The stone reads "Godfrey Shreve, one of the heroes of the Revolution.Born 1758.Died 1835 in his 77th year."
The cemetery is near South Cambridge in NY, at the side of the road.It is surrounded by a wrought iron fence, now rusted, of course.The cemetery itself looks to be well cared for.
The cemetery inscriptions were published in the New York Genealogical and Biographical Record in October of 1917, p. 409.They are also to be found on LDS film #0017632.
I have a photo of the stone and could try to send a scanned copy of it to you, if you would like.Send me a private e-mail.
What is your interest in this gentleman?His sister Elizabeth Shrieve Cornell was my direct ancestress.There were many Shrieve/Shreve families in the Cambridge area at one time.The Cornells are still heavily represented there.
I have thought that Godfrey went to New York after the death of his wife Ruth, because he had no children in Ohio to care for him.However, that is a hunch.Do you know of any children?
