This gravestone was found just below the surface and is partially covered by another gravestone.
All that is visible is the number 6.
From the position of the 6 we believe this is stone no 109.
The following information is taken from “Monumental Inscriptions (Pre 1855) in Renfrewshire” :-
I.I. I. S. 1706
These could be the initials of John Jamphra (a tailor) and his wife Jean Smith
