As you can see this gravestone is tucked away in a corner of the graveyard, in a corner next to the grave memorial for another Reverend, built into the wall separating the graveyard from the Main Street. It has deteriorated to the extend that it can no longer be read although I could just about descern the name of the deceased. Here is the text according to Peeblesshire Monumental Inscriptions - pre 1855, compiled by Sheila A. Scott.
In memory of
writer to the Signet
third son of Reverend William Keyden
minister of Penpoint, Dumfriesshire
born 15th September 1768
died 5th January 1826
Quite sad to see it in such a decrepit state, with all that wood piled in front of it!
